The development of chemistry into an independent branch of science

The world's first professorship for chemistry was established in Marburg in 1609. European students and professors were already astonishingly mobile. In the 19th century, chemistry became an important driving force in industry and science. In Germany, chemistry did not become an independent branch of science until the 20th century. The lecture will discuss the development of the subject of chemistry in Europe up to the 20th century.

Target group: teachers, students in advanced courses, chemical specialists in training, German Young Chemists Network - Duration: 60 min


The working situation of chemists in Europe

Employment conditions and career opportunities were the focus of the survey of European chemists. The results provide important information for many EU countries and for Europe as a whole. The requirements of the job market for chemists differ significantly between countries. This is important for career planning, and not just for students and graduates.

Sweeteners, the sweet side of chemistry

Sugar substitute. Instead of a chemical success story of sweeteners, a drama begins whose plot is determined by economic interest groups, tax legislation, the market, wild gangs of smugglers and the spirit of the times. But also a strong pinch of gripping chemistry. Let's take a closer look at the 10 sweeteners approved in the EU today and enjoy the agony of choice.

Crime Scene Berlin: Berlin Blue

its discoverers and traitors

Around 1700, Berlin was a hive of activity. Bright minds were recruited from all over Europe and flocked to the city. They were welcome, no one asked about their religion, they were allowed to try their luck. Although alchemy had already passed its zenith, it reached its peak in popularity. A colorful startup scene developed in the city, and in 1706, the discovery of the century was made in Prussian blue. From the very beginning, many legends and stories were associated with this. Let's reopen the case and finally close it, thanks to new research into the history of chemistry.

The chemical secret of a Stradivarius

When a violin virtuoso enchants us with the sound of his Stradivarius, we think he is very, very far removed from chemistry. This is deceptive, because chemistry played and continues to play an important role in Stradivarius' workshop, in the strings, the bow and the care of the instrument. So let's listen to the sound of a Stradivarius with a chemical ear.

Absinthe - The Kiss of the Green Fairy

Absinthe is in! After many decades of total prohibition, this drink has been allowed to be sold again in Germany for a few years. It was the favorite drink of the Parisian bohemians of the late 19th century. After a few glasses of absinthe, many gifted painters, musicians and poets hoped for the embrace and kiss of the Green Fairy, which would release unexpected bursts of creativity. What is behind it and can we still hope for the Green Fairy today? So let's get to the (chemical) reason behind it. À votre santé!

From the Isenheim Altar to the Beatles

On the Isenheim Altar, Mathias Grünewald disturbs us with his imaginative depiction of the "Temptation of Saint Anthony" with a host of terrible demons who harass and torture the desperate saint from all sides. We are particularly moved by a cripple covered in boils who suffers unspeakable pain, the result of the widespread epidemic "St. Anthony's fire". It took centuries for this epidemic disease to be recognized as poisoning from the ergot fungus that grows on rye. Let us examine the disastrous influence that ergot poisons have had on the history of mankind.

Target group: Students, teachers and the school community – Duration: 45-60 minutes

Chocolate – a chemical sensory rush

Chocolate is a feast for all the senses: the silky dark brown, the wonderful cracking sound when you break off a small piece, the scent that brings back memories of childhood and finally the gentle melting on the tongue. The secret of good chocolate lies in the ingredients of the cocoa bean, which are chemically refined during fermentation and roasting. Heavenly pleasures can only be achieved with a strong dose of chemistry.

From the first beer to the hangover

The condition of the sick is worrying: nausea, vomiting, trembling limbs, sweating, deathly pallor, headaches and poor circulation. Instead of compassion, the eyes of loved ones only flash with glee: "Was the 12th beer bad?", "Serves you right, you couldn't get enough." How can such a small molecule as ethanol cause so much human suffering? Let's explore the chemical consequences of a boozy evening.

Target group: Students, teachers and the school community – Duration: 45-60 minutes

Can chemistry be kosher?

Products from the chemical industry improve the quality of life of people all over the world. Consumers expect that the raw materials, manufacturing processes and end products meet the highest standards. But people of some religious communities expect even more: compliance with religious regulations throughout the entire manufacturing process. Let us study this unusual border area between chemistry and religion using Islamic and Jewish laws as an example.

Target group: Students, teachers and the school community – Duration: 45-60 minutes

H 2 O – tapped and originally corked

Water is extraordinary and amazes with so many oddities that it is no wonder that scientists have long been struggling to understand this small molecule. In addition to the remarkable successes in researching the properties of H2O in all states of matter, water offers a huge playground for scientific nonconformists, naive amateur researchers and cunning business people. Let us shed light on the colorful and sometimes shrill world of water on both sides of the borders of exact science with goodwill, critical distance and a large portion of gallows humor.

Tattoo – chemistry that gets under the skin

“There is no nation, from the polar regions in the north to New Zealand in the south, in which the inhabitants do not tattoo themselves,” Charles Darwin stated in his “Origin of Species.” The current renaissance of tattooing is thus simply taking up a tradition that has been cultivated in many cultures for many centuries. As early as 2009, one in four Germans aged 25 to 34 had a tattoo, and in Europe over 100 million people had one. But what happens to our skin during and after color pigments are introduced into the deeper layers of the skin? Let's look at a tattoo from a chemical point of view right from the start.

Target group: Students, teachers and the school community – Duration: 45-60 minutes

The chemical secret of the Christmas scent

Every year on the first Sunday of Advent, many kitchens are transformed into small bakeries where people make cookies and other baked goods together. Then the smell of freshly baked Christmas cookies, cinnamon stars, stollen and gingerbread wafts through the living rooms. No other festival is as closely linked to smells as Christmas, and this sensory impression remains a happy and longing memory for the rest of our lives. Let's follow the scent trail and try to find out its chemical basis. The effort will be rewarded, because with the new knowledge, the Christmas treats taste even better.

Of sailors, guinea pigs and citrus fruits

We humans are by no means biochemically perfect. On the contrary, we have to ingest many vital substances through food because our bodies cannot produce them themselves. If we lack these substances, we become ill. A lack of vitamin C hits us particularly hard, because then we get scurvy. It is not even 100 years since the molecular cause of this terrible disease was discovered and humanity was freed from it forever. A look back at the many trials and tribulations of the centuries-long fight against scurvy and in gratitude for the brave captains, Nobel Prize-winning chemists and physiologists and of course especially for the guinea pigs.

The chemistry of espresso

Espresso is harmless to health, stimulates the mind, does not make you fat and even has the papal blessing. Can you really ask for more? A cup of espresso is easy to prepare: 50 roasted and ground coffee beans are pressure extracted in an espresso machine. It's not that easy! There's a lot of chemistry behind it! Let's look at espresso from a chemical point of view and in the future we'll be able to sip the tempting crema with twice the pleasure.

Chili – some like it spicy (with samples)

People all over the world use plant species from the Capsicum genus to spice up dishes visually and in terms of taste. Hungarian, Mexican, Korean and Indian cuisine would be unthinkable without their characteristic spiciness. How does Capsicum manage to synthesize chemical compounds that irritate our tongue just enough for us to perceive it as a pleasant spiciness? Let's uncover the scientific background of the slowly diminishing burning sensation on the tongue and enjoy spicy dishes even more consciously in the future.

Excited states for exciting chemistry

Curricular innovation research in chemistry education

Chemistry plays a key role in the development of photoprocesses for other STEM subjects, too, because one of its characteristic features is the explanation of macroscopic phenomena using models at the (sub)microscopic particle level. In this sense, electronically excited states of molecules and other particle associations are common to all photoprocesses with and without chemical reactions. The fact that excited states can be used to teach chemistry, physics, biology, computer science and geography in a stimulating, efficient, sustainable and future-oriented way is discussed in the lecture and demonstrated using a number of experiments*. Experiments and other digital teaching/learning materials are available online on the Chemistry with Light internet platform.

Target group: Students, teachers and school community - Duration: 45-60 min

On the way to artificial photosynthesis

Lights on! Even in chemical education!

The lecture will explore the path to artificial photosynthesis using model experiments*, in which essential elementary processes and energy conversions in the natural photosynthesis-cellular respiration cycle are initially simulated. The direct, light-driven production of hydrogen without the detour via photovoltaics and electrolysis will then be demonstrated experimentally*. This will introduce one of the future scenarios for sustainable "green chemistry" based on climate-neutral, photocatalytically produced solar hydrogen. See also films on the University of Wuppertal's " Chemistry with Light " internet platform.

Target group: Students, teachers and school community - Duration: 45-60 min

Photosynthesis - a case for two

Interaction of chlorophyll and β-carotene in photosynthesis

Carotenoids are interesting substances from everyday life, especially their most important representative, β-carotene. Thanks to its interesting properties, β-carotene is a chemical, biological and didactic all-rounder that can add a "colorful touch" to chemistry and biology lessons from the beginning to the high school diploma and can be used to develop or apply technical terms, concepts and models of chemistry and biology. The lecture will present experiments and appropriate integration options for a modern curriculum. Videos and films of the experiments are available online on the University of Wuppertal's website under Photosynthesis - a case for two, part 2.

Target group: Students, teachers and school community - Duration: 45-60 min

Photo & Nano - a strong pair

Thin layers with key functions

Photoactive nanomachines in biological functional units initiate the process of vision in our eyes and photosynthesis in green leaves. But why are they "photo and nano"? Because their driving force, light, cannot penetrate deep into the materials, but is absorbed at the surface, and nanostructured materials are ideally suited for this.

Evolution has produced ingenious biomaterials of this kind. Light-absorbing species are usually combined with protein macromolecules. Inspired by nature, materials science researchers are researching analogous materials for technical applications. And here, too, light-absorbing molecules are combined with networks of organic polymers or inorganic ionic lattices to create so-called nanocomposites. This innovative type of material is crucial for photovoltaics and photocatalysis, for example.

The lecture will explore the underlying concepts of these two research areas under the motto photo & nano. Experimental approaches will be demonstrated and conceptually linked to curriculum-compliant content in order to apply, deepen and expand on these. Slides from the presentation and other materials are available online under Chemistry with Light.

Target group: Students, teachers and school community - Duration: 45-60 min

Luminescence - a paradigm shift for color

“The colors are acts of light”

Goethe was absolutely right with the quote from his "Theory of Colors" quoted in the subtitle. However, his view of the composition of white light was wrong. In the lecture , the question "What is light?" is embedded in a cultural and scientific historical excursion from ancient Egypt to Einstein's photoelectric effect and light quanta. Both the historical milestones and our everyday experiences today with the "normal" colors of fabrics in white light and the luminescent or glowing colors, e.g. textiles in disco lights or screens on electronic devices, confirm that "colors are acts of light."

Luminescence in its various forms, e.g. fluorescence, phosphorescence, electroluminescence, chemiluminescence and bioluminescence, are highlighted in the lecture and illustrated with suitable experiments. Its conceptual explanation represents the paradigm shift claimed in the title, because unlike "normal" colors, luminescent colors are not created by light absorption, but by light emission. This is a paradigm shift that must be implemented in many school books and curricula that are still in use today. Digital materials on the title topic are available on the Internet under Chemistry with Light.

Kleine Moleküle, große Wirkung

Spurengase in der Atmosphäre

Zu seinem Berufseinstieg 1977 kam der Autor erstmals mit den Produkten der menschlichen Aktivitäten in Gestalt des kleinen Moleküls  CF4 in Kontakt. Nach aufwendiger Aufarbeitung riesiger Mengen Luft in kryogenen Rektifikationsapparaten zu Krypton und Xenon fand sich eine Spurenverunreinigung im Krypton, die die industrielle Verwendung als Lampengas in Gefahr brachte. Ausgehend von dieser Begebenheit zu Anfang seiner Berufstätigkeit war er in seinem weiteren Berufsleben immer wieder mit den Hinterlassenschaften industrieller Tätigkeiten in der Atmosphäre konfrontiert, kulminierend mit dem in den achtziger Jahren entdeckten Ozonloch und den schädlichen Wirkungen des bodennahen Ozons. Schritt für Schritt werden an diesen experimentellen Befunden die Forschungen an der Atmosphäre und die modernen Bedrohungen des irdischen Lebens durch die Verbrennung von fossilen Stoffen zur Energiegewinnung aufgezeigt.

Water - an everyday miracle?!

The "elixir of life" water is an indispensable part of the earth: 70% of the earth's surface is covered with water, organisms such as jellyfish consist of up to 99% water and even humans carry 68% of their weight in this liquid. The moist "element" has many interesting properties. Using experiments that can usually be easily carried out at home and video sequences, Dr. Gerhard Heywang, who used to work at Bayer AG in Leverkusen, shows various phenomena. The answers to the following questions are among others: Can you glue panels together with a drop of water that isn't even drop-shaped (!)? Why does a thermometer in ground ice show a temperature of around +2°C? Why do windows and mirrors fog up when you shower?
Duration: 90 minutes
Target group: High school classes and school community

Splish Splash

Plastics are simply great!

Today, it is hard to imagine an area of ​​our lives in which plastics do not play an important or even decisive role. The nature of plastics means that interesting physical properties can be achieved. The lecture will present various experiments on the special properties and synthesis of plastics. The versatility of use will be demonstrated using many application examples. It can be seen that plastics are much more than "just plastic". For weight reasons, the intake manifolds in the engine compartment of cars, for example, are made of polyamides. The tear resistance of plastic fibers exceeds that of steel. The field of functional polymers has recently become increasingly important. Electrically conductive polymers and superabsorbents are presented as examples.

The chemistry between 6:30 and 7:30

In the hour after waking up, people are confronted with a multitude of chemicals and chemical products - usually in a very pleasant way! The experimental lecture sheds light on the many facets of where and how chemistry encounters us humans in the morning. In the first hour after getting up, we encounter plastics, which is OK, but also acetaldehyde, furfurylthiol and sotolon. Surfactants are allowed to act on the body and attempts are made to get rid of them again using the biosolvent water.

What makes us vibrate?

How do our vocal cords work? Why do standing waves occur in a pipe that is open at both ends when you hit it with the flat of your hand? Why do sounds come out of a flute when you blow into it but not out of a garden hose? Can you still make music with a garden hose? Does a piano really only produce 88 notes? These and other questions about music and acoustics are answered and explained in an entertaining way using numerous simple experiments.
Duration: 70 minutes
Target group: High school classes and school community

Do you have any sounds?

The question “Do you have any tones?” is ambiguous:
1) Can you produce sound? This is explained using vocal cords, pipes, horns and flutes and the physical principles behind them.
2) Do you have any words? I hope you won't be speechless, but the physics and chemistry experiments (plastics and water) are amazing.
Parts 1 and 2 are closely interwoven, and there is no denying that they are entertaining. Many of the experiments can be easily carried out at home. The experiments all have a connection to everyday life and are ideal for science lessons - with certain simplifications, they are mostly even suitable for primary school.

Sparkling wine – also scientifically sparkling

Sparkling wine embodies concepts such as luxury, festivity and enjoyment. Sparkling wine is a sparkling, fine wine that is a must for celebratory occasions and special moments in life. This tradition came to Germany towards the end of the 18th century, and with it the secret of the highly sensitive fermentation process. But how did sparkling wine actually come about, and which ingredients ultimately make it such a delicious drink? Who would think that the pressure in a bottle of sparkling wine is higher than that in a car tire? Experiments are presented on the ingredients water, carbon dioxide and ethanol.
Phenomena that can be observed in sparkling wine are also of importance in technology and nature. The Lake Nyos disaster (1,800 deaths and 30,000 animals killed) and cold geysers are also discussed. The role of the silver spoon in supposedly ensuring the quality of sparkling wine in an opened bottle in the refrigerator is also explained.

Electrically conductive polymers - history and current applications

The structural and chemical requirements for electrically conductive polymers are derived using polyacetylene as an example. Conductivities equivalent to those of iron have been achieved with polyacetylene, but the processing options are quite limited and the long-term and thermal stability are completely inadequate. Soon after the discovery of polyacetylene, polypyrrole, a much more stable material, was introduced, which also made technical applications possible. With polyethylenedioxythiophene, the processability and stability could be further developed to a great extent, resulting in a breakthrough for technical applications. There are now a number of different possible uses: antistatic coatings in photo films, borehole plating of circuit boards, counter electrodes in solid electrolytic capacitors, monitor coatings and organic light-emitting diodes (OLEDs). The applications are presented and the advantages of using electrically conductive polymers compared to conventional systems and problem solutions are explained. The breakthrough of polyethylenedioxythiophene in technical products has been made possible not least because the material can be applied as a dispersion and because the polymer can be produced specifically where its functional properties are needed.

The tongue - a jack of all trades

The tongue is a very versatile organ. It helps with speaking, swallowing, chewing and many other activities in the mouth. The tongue consists of 9 different muscles, each of which can only contract, but you can still stick your tongue out. How does that work? And how does it work when a chameleon can catapult its tongue out as long as its own body? In the lecture, test subjects will investigate how taste develops and which flavors can be perceived with the tongue. Does salt always taste salty and is hot chili healthy? Who can roll their tongue? And what happens when you roll an R? All in all, it's about the chemistry and physics in the mouth.

Something is dripping – (almost everything about drops)

A raindrop is round – no, almost round! It looks like a bread roll from the side. There are also round drops if they are small enough. There are also drops that are hemispheres, for example on a window pane. The shape referred to in German as a “drop shape” exists in art and advertising, but is very rare in practice. Examples are shown. Water drops with very unusual shapes play a very important role in building sandcastles, and this is why sandcastles remain standing for a considerable time after they have been built. Extremely unusual drops are demonstrated: water with corn starch forms a “paste” which enables particularly unusual drops. There are also coffee drops, wine drops, honey drops and very special “nervous” drops which a theologian understood and described for the first time.

Honey and sweets from nature

During photosynthesis, carbon dioxide reacts with water in plants under sunlight. This produces oxygen and carbohydrates. A small proportion of the carbohydrates are low-molecular sugars. A much larger proportion is starch, and the majority are cellulose chains, the structural substance of all plants. Sugar is found in varying proportions in flowers (nectar), branches and plant stems, and in roots. Aphids also secrete sugary solutions, and mammals produce galactose (milk sugar) in their mother's milk to feed their offspring. The experiments involve honey and household sugar.

Lithium: the white gold of the Andes

The largest deposits of lithium are found in the Andes of Latin America. The rare metal lithium has become increasingly important in recent decades due to mobile electronic devices such as smartphones, laptops and, above all, electric cars. Lithium occurs on earth in so-called salars as brine and in ore deposits in the form of pegmatite. The brines are processed by water evaporation and precipitation due to the different solubilities of the salts found in the lakes. The lithium carbonate obtained in technical quality can be filled into bags, shipped and easily processed further. The most important application of lithium is the lithium-ion battery. Lithium itself is produced from lithium chloride using molten salt electrolysis. Will lithium deposits be sufficient in the future? It is therefore important to develop technologies to recycle raw materials. There are now interesting developments, one from Evonik will be presented at the end.

Value chains in industrial organic chemistry

Industrial organic chemistry is a complex, flexible network that has developed over a period of more than 150 years and is still constantly evolving. A limited number of basic and intermediate products are produced from a few raw materials, each of which is the starting point of value chains leading to a large number of end products. Using propene as an example, the lecture shows how one gets from crude oil to superabsorbents or emulsion paints.

Homogeneous catalysis in the chemical industry

Catalysts are substances that lower the activation energy of a reaction system so that the desired reaction can proceed at high speed. Their high selectivity results in a low amount of by-products - which is not only an economic advantage, but also protects our environment. Homogeneous catalysts are soluble metal complexes whose activity and selectivity can be tailored to the desired product. The lecture gives examples of industrially used, highly selective processes both for large-volume products (e.g. acetic acid) and for specialties such as optically active compounds for pharmaceuticals (e.g. the Parkinson's drug L-DOPA).

Chemical products are omnipresent in our everyday lives. Examples include packaging, pharmaceuticals, cosmetics, pesticides, detergents, textiles and much more. The basis for this diversity is organic chemistry, whose products are omnipresent in our everyday lives. But inorganic materials also have a decisive influence on our lifestyle. They are the basis for high-tech products such as flat screens, solar cells, smartphones, computers and high-performance batteries. We need raw materials for all of these products, and they are finite. As the lecture shows, by improving our processes we can use new raw materials and also make better use of the raw materials we have used so far, including through new material cycles.

Chemical use of carbon dioxide – what is possible and what makes sense

Carbon dioxide is the carbon carrier of our planet. Photosynthesis/sunlight created all naturally occurring organic compounds, including fossil fuels. Even though carbon dioxide is an extremely low-energy molecule, it can still undergo chemical reactions. However, this requires high-energy reaction partners such as hydrogen, ethylene oxide or ammonia. The lecture will present established syntheses using carbon dioxide as well as new ones that are currently being developed. These include very large-volume syntheses of fuels (e-fuels). However, their need for (sustainable!) energy is enormous.

Energy, our elixir of life – where does it come from, where does it go?

Following the motto "Use numbers, not adjectives", the lecture places the political discussion about renewable energies and climate change in the context of the dimensions of our current energy system. Access to affordable energy sources has driven the development of human societies in the past. Standard of living and per capita consumption of primary energy correlate significantly, but the values ​​vary considerably.

The targets for reducing greenhouse gas emissions are most likely only realistic if the replacement of fossil primary energy with renewable (solar) Literature is combined with a much more efficient use of energy. The latter is not only a technical issue, but also a social and behavioral one.

Changes in the use of raw materials for the chemical industry

The chemical industry in Germany currently has a share of around 5% of the world market. Its carbon-containing products are mainly made from oil (72%) and gas (14%). At least 13% of the products are based on renewable raw materials. Coal plays practically no role at less than 2%. In total, the German chemical industry uses around 20 million tons of organic raw materials and the same amount of inorganic raw materials such as table salt.

The raw materials of the chemical industry have been and are constantly being adapted. At the beginning of the 19th century, wood was the raw material. Later, coal changed the entire industry and growth accelerated. After 1945, oil became the globally dominant raw material. Currently, however, coal is (again) gaining importance in China and especially in the USA.

The future of raw material supplies will therefore be more diverse than in the past; there will no longer be a single dominant global raw material. Instead, there will be a much greater regional diversification of raw materials. This will require globally active companies such as BASF to significantly broaden their technology portfolio.

Industrial catalysis - a crucial success factor for the chemical industry

Catalysts play a central role in the processes of the chemical industry. Both the raw materials and the energy requirements of processes depend crucially on the quality of the catalysts used.

The development of such products is an extraordinarily diverse and challenging task. To master it, one must master a large number of technical disciplines. A technical catalyst is much more than an "active center" and is often the result of a balanced compromise between several actually contradictory target variables.

The lecture highlights these aspects and uses a concrete example to show the unconventional results that such a development process can lead to.

Raw material change in the (petro)chemical industry

The chemical industry in Germany currently has a share of around 5% of the world market. Its carbon-containing products are mainly made from oil (72%) and gas (14%). At least 13% of the products are based on renewable raw materials. Coal plays practically no role at less than 2%. In total, the German chemical industry uses around 20 million tons of organic raw materials. The chemical industry is an energy-intensive sector, the most important energy sources are gas and electricity.

The raw materials of the chemical industry have been and are constantly being adapted. At the beginning of the 19th century, wood was the raw material. Later, coal changed the entire industry and growth accelerated. After 1945, oil became the globally dominant raw material. Currently, however, coal is (again) gaining importance in China and gas in particular in the USA. The lecture will explain the criteria used to select the raw material base at different locations. Technical processes for using all raw materials are known.

On a global scale, the chemical industry is the third largest industrial emitter of CO 2 after steel and cement, with a share of 8%. The key to reducing this share will be the availability of "green" electricity and hydrogen without an atmospheric CO 2 backpack. Increasing the amount of carbon used from renewable raw materials is reaching ecological limits.

Carbon - real gold

No other element allows for such a wide range of reaction possibilities as carbon. Beyond organic chemistry with its main protagonist carbon, carbon can even be found in space as diamond (unfortunately difficult to access) but also in the soil as a fossil fuel, coal. Technical progress in materials science is often linked to our record-breaking properties (e.g. electrical current density [109 A/cm²] ─ 100 times higher than copper). The example of carbon shows how scientific findings can stimulate technology and the economy: the basis of the chemical industry!

Carbon in the atmosphere also influences the temperature through CO 2 and soot particles. The magnitude of the effect is controversial, however. After the lecture , everyone knows: carbon is a more valuable material than gold!

Target group: Students from MINT schools, especially from MINT advanced courses; science teachers, school communities, support associations, adult education centers, chemistry teacher training centers, SEC (annual meeting, science forum, SEC lecturer) - Duration: 45-60 minutes

Efficient electric heating with carbon

Heating with carbon is nothing unusual. Any coal-fired stove provides a good example. But you can also use the carbon for heating without burning it if you put electricity into it. Imagine a carbon dispersion that you paint onto the wallpaper like wall paint with a lambskin roller, connect it to the right and left with a copper strip and apply a voltage. Why does this have a different effect on our bodies than normal radiators? What other interesting things can you do with a "paintable" heater?

Fiber composites – efficient materials based on nature

When nature needs stable structures, it does not create "bulwarks," but uses the combination of materials of varying density and strength, mostly with fibrous components. Wood is a typical example of this. But why is this combination of materials so important? Why does a pane of glass break when bent, but fiberglass does not? Also interesting: why are airplanes mostly made of fiber composite structures and cars almost not at all?

When does an investment pay off? Dealing with risk

Management theory insists that only with an investment calculation can a company successfully move into the future. Even the layman can see from various press reports that new plants or company acquisitions have not achieved the expected success despite an investment calculation. It is therefore interesting to find out what the calculation can do and where its limits are. Because there is always a risk that often pales behind grandiose promises.

How can one calculate the IR absorption of CO 2 using “on-board resources”?

After reading Wikipedia about "greenhouse gas" you think you understand how CO 2 works in the atmosphere. However, what is surprising is the statement that it contributes between 9% and 26% to the greenhouse effect, although the global concentration differences are very small in contrast to water vapor!

Using the relatively simple Lambert-Beer photometry equation and spectroscopy data from the Internet (e.g. from HITRAN.org), you can calculate in Excel that the greenhouse effect of CO 2 is at least 26% - however, the total greenhouse effect is much, much smaller than generally stated. (Is this effect really comparable to the greenhouse?)

You don't have to be a "climate expert" to understand the lecture . Knowledge of mathematics and physics from a high school level is sufficient.

Plastic waste: knowledge and speculation

The time for dealing with materials mindlessly is slowly coming to an end. This is very positive in many respects. But is the damage caused by plastic waste and microplastics, which has been shown to be a threat, a legitimate justification for this? What is the truth behind "plastic on the plate" and how do we find the huge islands of plastic waste in the Pacific?

Energy efficiency through material selection

The highest form of energy efficiency is usually not having to convert energy. But when we do convert energy, it is usually for movement or for heat Management (heating, cooling). In moving bodies, the energy "consumption" depends on their mass, which is why lighter materials are preferable; does this really always apply? The first choice for efficient heat utilization is foam-like materials. But not only that!
