The world's first professorship for chemistry was established in Marburg in 1609. European students and professors were already amazingly mobile. In the 19th century, chemistry became an important driving force in industry and science. In Germany, chemistry only became an independent branch of science in the 20th century. The lecture discusses the development of the subject chemistry in Europe up to the 20th century.
Target group: Teachers, students in advanced courses, chemical specialists in training, Young Chemists Forum ' forum - Duration: 60 min

Humanity grows and grows - but the area of fertile arable land not only remains constant; it even decreases due to erosion, urban sprawl and other influencing factors. Will the amount of greenhouse gases formed, or simply the "CO 2 footprint", set the standard for assessing what should and should be prohibited? Does the enjoyment of a good steak even become an "ecological sin"?
In order to find answers here, one has to think in an interdisciplinary manner and in larger contexts, based on facts. On the basis of the World Agriculture Report, questions of soil fertility and sustainable agriculture are dealt with, aspects of the anthropogenic influence on the climate are discussed and what really defines a sustainable lifestyle.
Target group: students from 11th grade - duration: 60-90 min
Cultural monuments, world heritage - these are well-known UNESCO themes. But why are engineers so interesting and important for the global community today? Engineering enables the creation of "technical creatures". We are surrounded by them all around us and they have changed our everyday life in unexpected ways. But can engineers still afford to be interested in technology alone today? In what contexts do technical developments have to be considered today?
More than ever, ethically sound action is required, because we are reaching the limits of the resilience and resources of our mother ship Earth. In 2011, UNESCO called for this in the ?Engineering Initiative?, and in 2013 UN Secretary General Ban Ki-Moon declared that ?Science, Technology and Innovation, STI? are indispensable for the further development of the global community. The development goals drawn up for the period after 2015 have already been defined as ?Sustainablemilleniumdevelopmentgoals, SDG?.
How important an interdisciplinary, even interdisciplinary approach to technical issues is, is explained using various examples. They make it clear that the best minds are required here in order to find sustainable, ie ecologically, socially and economically viable solutions.

The experience of "biodiversity" begins in everyday life - for example with food. 75,000 plant species are edible, but today we cover around 90% of the world's food with only 20 plant species.
But what does nature have to offer us and what teasing jokes does it play with us while hiding its true intentions in a playful way?
From the wonderful abundance of plant-based foods, schoolchildren (of all ages) get to know interesting examples of plant-based foods that are important for nutrition. Interesting "secondary plant substances" can also be dealt with in advanced school levels.
Target group: Every school level, also suitable for elementary school, useful: as vocational training for teachers - duration: 60-90 min
Note: For this event you have to plan around 25-30 ? for the purchase of plant-based foods. In order to achieve a broad impact, it is advisable to conduct a further training course for teachers - because the effort as a guest speaker is quite high and multiple "hires" for a school are only possible to a limited extent.
The global protection of our earth's natural resources, which has become necessary, can only be successful if it does not start with thinking about our own consumption. Every day, for example, the rainforests necessary to maintain biodiversity and a balanced climate are cut down on a large scale. In their place, the agricultural industry is expanding, often with genetically modified soy, corn and wheat. The whole world is supplied.
Numerous good ideas and realized examples of how one can be active in matters of healthy nutrition, short delivery routes, better food quality, i.e. simply environmental protection, exist all over the world and in the local region. They are intended to illustrate how the United Nations' 2030 Agenda with its 17 Sustainable Development Goals, which serve sustainable development, can be implemented.

Man can turn around at any moment - says Martin Buber, one of the great thinkers of the 20th century. It is possible to decide differently and to turn back when the voice of conscience stirs!
But we don't often find ourselves in situations in which we lack this "moral courage" or in which, while reading biographies, we wonder why he or she didn't say no - even when it seemed to be without danger to life and limb ?
We can learn a lot from the example of the profound conflict between Clara Immerwahr and her husband, Fritz Haber. What stopped Fritz Haber from hearing his wife's voice, her warnings about the consequences of the use of poisonous gases in World War I? And what does that mean for us today?
Perhaps dealing with this page of Nobel Prize winner Fritz Haber is a piece of the mosaic on the way to learning from history and not repeating the same mistakes over and over again in human history.

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

Around 1700 the bear was tapping in Berlin. Bright minds were recruited from all over Europe and poured into the city. They were welcome, you didn't ask about your religion, you let them try their luck. Although alchemy was past its zenith, it was at its height in popularity. A colorful start-up scene developed in the city, in which in 1706 a discovery of the century was made with the Berlin blue. That is why many legends and stories have grown up from the start. Let's roll up the case again and finally close it, thanks to new research in the history of chemistry.

When a violin liquor enchants us with the sound of its Stradivarius, we believe we are very far away from chemistry. This is deceptive, because chemistry played and still plays an important role in Stradivari's workshop as well as with the drawn strings, the bow and the care of the instrument. So let's listen to the sound of a Stradivarius with the chemical ear.

Absinthe is trendy! 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 or poets hoped for the green fairy's embrace and kiss, which unleashed unexpected bursts of creativity. What is behind it and can we still hope for the green fairy today? So let's get to the bottom of it (chemical). À votre santé!

On the Isenheim Altar, Mathias Grünewald disturbs us with the imaginative depiction of the "Temptation of St. Anthony" with a host of very terrible demons who harass and harass the desperate saint from all sides. We are particularly touched by a cripple covered with boils and suffering unspeakable pain, consequences of the popular epidemic ?Antoniusfeuer?. It took centuries for this epidemic disease to be recognized as a poisoning of the ergot fungus growing on rye. Let us shed some light on the fateful influence the poisons of ergot have played in human history.

Chocolate is a feast for all the senses: the silky matt dark brown, the wonderful cracking when a small piece is broken off, the scent that brings back memories of childhood and finally the gentle melting on the tongue. The secret of good chocolate is based on 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.

The condition of the sick is worrying: nausea, vomiting, trembling limbs, outbreaks of sweats, pale corpses, humming skulls and poor circulation. Instead of sympathy, the loved ones' eyes only gleam with glee: "Was the 12th beer bad?", "Serves you right, you couldn't get your throat full enough". How can a molecule as small as ethanol cause so much human suffering? Let's explore the chemical consequences of a wet and happy evening.

Chemical industry products improve people's quality of life all over the world. Consumers expect that the starting products, manufacturing processes and end products meet the highest standards. But people of some denominations expect even more: adherence to religious regulations throughout the manufacturing process. Let us study this unusual border area between chemistry and religion using the example of Islamic and Jewish laws.

Water is extraordinary and amazes with so many peculiarities that it is no wonder that natural scientists have long had their teeth on the small molecule. In addition to the considerable successes in researching the properties of H2O in all aggregate states, water opens up a huge playground for scientific nonconformists, naive amateur researchers and savvy businessmen. Let us shed light on the colorful and sometimes shrill world of water on this side and on the other side of the limit of exact natural sciences with benevolence, critical distance and a large portion of gallows humor.

"There is no nation, from the polar regions in the north to New Zealand in the south, in which the inhabitants do not have tattoos," said Charles Darwin in his "Origin of Species". The current renaissance of the tattoo therefore only takes up a tradition that has been cultivated in many cultures over many centuries. As early as 2009, every fourth German between the ages of 25 and 34 was tattooed and over 100 million people in Europe. But what happens to our skin during and after the introduction of color pigments into the deeper skin layers? Let's follow a tattoo from a chemical point of view from the beginning.

Every year on the 1st of Advent, many local kitchens are transformed into small bakeries, in which cookies and other baked goods are made together. Then the scent of freshly baked Christmas cookies, cinnamon stars, stollen and gingerbread wafts through the living room. No other festival is so closely connected to smells as Christmas and this sensory impression remains in a blissful and longing memory for a lifetime. Let's record the scent trail and try to find out its chemical basis. The effort is rewarded, because with the new knowledge, the Christmas treats taste twice as good.

We humans are by no means perfect biochemically. On the contrary, we have to ingest many essential substances with our food because our body cannot produce them itself. If we lack these substances, we get sick. A lack of vitamin C hits us particularly hard, because then we get sick with scurvy. It is not even 100 years ago that the molecular cause of this terrible disease was cleared up and humanity was set free from it forever. A look back into the many trials and tribulations of the centuries-old struggle against scurvy and in gratitude for the brave captains, Nobel Prize-winning chemists and physiologists and of course especially for the guinea pigs.

Chemistry also plays a key role in the development of photoprocesses for other STEM subjects, because one of its characteristic features is the explanation of macroscopic phenomena with the help of models at the (sub) microscopic particle level. In this sense, electronically excited states of molecules and other particle assemblies are common to all photoprocesses with and without a chemical reaction. That chemistry, physics, biology, computer science and geography can be conveyed in a stimulating, efficient, sustainable and future-oriented manner with stimulated states will be discussed in the lecture and demonstrated with a few experiments *. Experiments and other digital teaching / learning materials are available online on the Chemistry with Light Internet platform.

Photoactive nanomachines in biological functional units initiate the visual process in our eyes and photosynthesis in the green leaves. But why are they "photo and nano"? Because their drive, the light, cannot penetrate deep into the materials, but is already absorbed on the surface and nanostructured materials are ideally suited for this.
Evolution has produced ingenious biomaterials of this type. As a rule, light-absorbing species are combined with protein macromolecules. Inspired by nature, the materials science researches analog materials for technical applications. And here, too, light-absorbing molecules are combined with networks of organic polymers or inorganic ion lattices to form so-called nanocomposites. This innovative type of material is crucial for photovoltaics and photocatalysis, for example.
In the lecture , the underlying concepts of these two research areas will be developed under the motto photo & nano. Experimental approaches are shown and conceptually connected to curriculum-compliant content in order to apply, deepen and expand them. Slides of the presentation and other materials are available on the Internet under Chemistry with Light.
Target group: students, teachers and school community - Duration: 45-60 min
With the quote from his "Theory of Colors" quoted in the subtitle, Goethe was absolutely correct. However, his view of the composition of white light was wrong. In the lecture the question "What is light?" embedded in a cultural and scientific-historical excursion from Egyptian antiquity to Einstein's photoelectric effect and the light quanta. Both the historical milestones and our everyday experiences today with the "normal" colors of fabrics in white light and the luminescent or luminous colors, for example textiles in disco light or screens of electronic devices, confirm that "colors are deeds of light".
Luminescence in its various forms, eg fluorescence, phosphorescence, electroluminescence, chemiluminescence and bioluminescence will be highlighted in the lecture and illustrated with suitable experiments. Their conceptual explanation represents the paradigm shift claimed in the title, because unlike the ?normal? colors, luminous colors are not created through light absorption, but through light emission. This is a paradigm shift that has to be carried out in many school books and curricula that are still valid today. Digital materials on the cover topic are available on the Internet under Chemistry with Light.

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.

The "elixir of life" water is indispensable on 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 around 68% of their weight with this liquid. The wet "element" has many interesting properties. With experiments, which are usually easy to carry out at home, and video sequences, Dr. Gerhard Heywang, who used to work for Bayer AG in Leverkusen, noticed various phenomena. You get answers to the following questions, among others: Can you glue panels with a drop of water that is not drop-shaped at all (!)? Why does a thermometer in ground ice show a temperature of about +2°C? Why do the windows and mirrors fog up when you shower?

Today there is hardly an area of our life imaginable in which plastics do not play an important or even decisive role. The nature of plastics means that interesting physical properties can be realized. Various experiments on the special properties and synthesis of plastics will be presented in the lecture . The versatility of use is demonstrated by many application examples. Here you can see that plastics are much more than "just plastic". For reasons of weight, for example, the intake manifolds in the engine compartment of automobiles are made of polyamide. The tear strength of plastic fibers exceeds that of steel. The field of functional polymers has recently become increasingly important. Electrically conductive polymers and super absorbers are presented as examples.

In the hour after waking up, people are confronted with a plethora of chemicals and chemical products - usually in a downright pleasant way! The experimental lecture illuminates the diverse facets of where and how chemistry meets us in the morning. In the first hour after getting up we encounter plastics, that's still possible, but also acetaldehyde, furfurylthiol and sotolon. Surfactants are allowed to act on the body and you try to get rid of them with the bio-solvent water.

How do our vocal cords work? Why do standing waves occur in a tube that is open on both sides when you hit it with the flat of your hand? Why does a flute produce sounds when it is blown into it and a garden hose does not? Can you still make music with a garden hose? Does a piano really only have 88 tones? These and other questions about music and acoustics are answered and explained in an entertaining way using numerous simple experiments.
Duration: 70 minutes

The question "Do you have sounds?" is ambiguous:
1) Can you produce sounds? This is explained using vocal cords, pipes, horns and flutes and the underlying physical principles.
2) Do you (still) have words? I hope not to be speechless, but the physics and chemistry experiments (plastics and water) are always amazing.
Parts 1 and 2 are closely interwoven, with a certain entertainment value that cannot be denied. Many of the experiments can easily be carried out at home. The experiments are all related to everyday life and are ideally suited for science lessons - with certain simplifications, mostly even for primary school.

Sparkling wine embodies concepts such as luxury, festivity and enjoyment. Sparkling wine is a foaming noble drop that simply belongs on festive 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 the invention of sparkling wine come about, and which ingredients ultimately make it a delicious liquid? Who thinks that the pressure in a champagne bottle is higher than that in a car tire? Experiments are presented on the ingredients water, carbon dioxide and ethanol.
Phenomena that can be observed with sparkling wine are also of importance in technology and nature. Among other things, the catastrophe of Lake Nyos (1800 dead and 30 000 animals killed) and cold geysers are dealt with. The role of the silver spoon in supposedly ensuring the quality of the sparkling wine in an opened bottle in the refrigerator is also clarified.

Using the example of polyacetylene, the structural and chemical requirements for electrically conductive polymers are derived. With polyacetylene, conductivities were achieved that correspond to those of iron, but the processing options are quite modest and the long-term and thermal stability are completely inadequate. Soon after the discovery of polyacetylene, polypyrrole was presented as a significantly more stable material, which also made technical applications possible. With polyethylenedioxythiophene, the processability and stability could be further developed to a large extent, so that a breakthrough for technical applications was achieved. There are now a number of different possible uses: antistatic coatings in photo films, through-hole plating of printed 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 was not least possible because the material can be applied as a dispersion and because the polymer can be produced specifically where its functional properties are required.

A raindrop is round - no: almost round! He looks like a bun from the side. There are also round drops if they are small enough. There are also drops that represent a hemisphere; eg on the window pane. The structure, referred to in German as the "drop shape", exists in art and advertising, but only very rarely in practice. Examples are presented. Water droplets with highly peculiar shapes play a very important role in sandcastle building, and that is why sandcastles remain for a considerable amount of time after construction. Extremely unusual drops are presented: water with cornstarch forms a "pamp" that enables particularly idiosyncratic drops. There are still drops of coffee, drops of wine, drops of honey and very special “nervous” drops that a theologian understood and described for the first time.

During photosynthesis, carbon dioxide reacts with water in plants exposed to sunlight. Here, oxygen and carbohydrates are formed. A small proportion of the carbohydrates are in the form of low-molecular sugars. A significantly 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. Lice also secrete sugary solutions, and in mammals, galactose (milk sugar) is produced in breast milk to feed offspring. The experiments involve honey and household sugar.

The largest deposits of lithium are found in the Andes of Latin America. The rare metal, lithium, has become increasingly important in recent decades because of mobile electrical devices such as smartphones, laptops and especially because of e-cars. Lithium occurs on earth in so-called salars as brine and in ore deposits in the form of pegmatite. The brine is 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 in bags, shipped and processed further. The most significant key application of lithium is the lithium-ion battery. Lithium itself is produced from lithium chloride using fused-salt electrolysis. Will there be enough lithium deposits in the future? That is why it is important to develop technologies to recycle raw materials. There are now interesting developments, one from Evonik will be presented at the end.

Catalysts are substances that lower the activation energy of a reaction system so that the desired reaction can take place at high speed. Their high selectivities result in low levels 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 life. Examples are packaging, pharmaceuticals or cosmetics, pesticides, detergents, textiles and many more. The basis for this diversity is organic chemistry, the products of which are omnipresent in our everyday lives. But the inorganic materials also have a decisive influence on our lifestyle. Because 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 both use new raw materials and make better use of the raw materials we have used up to now, also through new material cycles.

Carbon dioxide is the carbon carrier of our planet. Photosynthesis / sunlight resulted in all naturally occurring organic compounds including fossil fuels. Even if carbon dioxide is an extremely low-energy molecule, it can still enter into chemical reactions. However, this requires high-energy reactants such as hydrogen, ethylene oxide or ammonia. Established as well as new syntheses in development with carbon dioxide will be presented in the lecture . This includes very large-volume syntheses of fuels, for example (e-fuels). However, their demand for (sustainable!) Energy is enormous.

According to the motto "Use numbers, not adjectives", the lecture puts 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 fueled the development of human societies in the past. Standard of living and per capita consumption of primary energy correlate significantly, but the values scatter remarkably.
The targets for reducing emissions of greenhouse gases 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 but also a social and behavioral issue.

The chemical industry in Germany currently has a share of about 5% in the world market. Their carbon-containing products are mainly made from the energy sources oil (72%) and gas (14%). After all, 13% of the products are based on renewable raw materials. At less than 2%, coal is practically irrelevant. Overall, the German chemical industry uses around 20 million tons of organic raw materials and the same amount of inorganic raw materials such as common 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 dominant global commodity. However, coal and especially gas in the USA are (again) gaining in importance in China.
The future of raw material supply will therefore be more diverse than in the past, there will no longer be a single dominant global raw material. Instead, there will be much greater regional diversification of commodities. This demands a significant broadening of their technology portfolio, particularly from globally active companies such as BASF.

Catalysts play a central role in chemical industry processes. Both the raw material and the energy requirements of processes depend crucially on the quality of the catalysts used.
The development of such products is an extraordinarily varied and challenging task. Mastering them requires mastering a large number of specialist 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 values.
The lecture examines these aspects and uses a concrete example to show what unconventional results such a development process can lead to.

The chemical industry in Germany currently has a share of about 5% in the world market. Their carbon-containing products are mainly made from the energy sources oil (72%) and gas (14%). After all, 13% of the products are based on renewable raw materials. At less than 2%, coal is practically irrelevant. In total, the German chemical industry uses around 20 million tons of organic raw materials. The chemical industry is an energy-intensive industry, the main sources of energy being 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 dominant global commodity. However, coal and especially gas in the USA are (again) gaining in importance in China. The lecture explains 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.

No element allows as diverse reaction possibilities as carbon. Beyond organic chemistry with its main protagonist carbon, carbon can even be found in space as a 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 property record master (eg electrical current flow density [109 A / cm²] ? 100 times higher than with copper). The example of carbon shows how scientific knowledge can inspire technology and economy: the basis of the chemical industry!
Carbon in the atmosphere also influences the temperature through CO 2 and soot particulate matter. The size of the effect is controversial. After the lecture everyone will know: Compared to gold, carbon is the more valuable material!
Target group: Pupils from MINT schools, especially from MINT advanced courses; Science teachers, school community, development associations, adult education centers, advanced training centers for chemistry teachers, SEC (annual meeting, science forum, SEC lecturer) - Duration: 45-60 minutes
Heating with carbon is nothing out of the ordinary. Every coal stove provides a vivid example. But you can also use the carbon for heating without burning it if you electrify it. This is how you imagine a carbon dispersion that you paint on the wallpaper with a lambskin roller like a wall paint, connect right and left with a copper tape and apply voltage. Why does it affect our body differently than the usual radiators? What other interesting things can be done with a ?paintable? heater?

When nature needs stable structures, it does not create "bulwarks", but uses a combination of differently dense and solid materials with mostly fiber-like 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 you bend it, but the glass fiber doesn't? Also interesting: why are airplanes mostly made of fiber composite structures and cars almost not at all?

The management theory insists that a company can only successfully move into the future with an investment calculation. Even the layperson recognizes from various press reports that new plants or company acquisitions failed to achieve the expected success despite the investment calculation. So it is interesting to find out what the calculation can do and where its limits are. Because there is always a risk that often fades behind full-bodied promises.

After reading Wikipedia about "greenhouse gas", you think you have understood how CO 2 works in the atmosphere. However, the statement that it contributes between 9% and 26% to the greenhouse effect makes us suspicious, although the global differences in concentration are very small in contrast to water vapor!
With the relatively simple photometric equation according to Lambert-Beer and spectroscopy data from the Internet (e.g. from HITRAN.org), after a calculation in Excel, one finds that the greenhouse effect of CO 2 is at least 26% - but the overall 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 the upper school level is sufficient.

The time to deal with materials without a head is slowly coming to an end. That is very positive in several ways. But is the damage caused by plastic waste and microplastic identified as a threat a legitimate justification for this? What is it about "plastic on your plate" and how do you find the huge plastic waste islands in the Pacific?

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