Young Scientist Award

Young Scientist Award from the GDCh Division of the Chemistry of Construction Materials

The Division of the Chemistry of Construction Materials of the German Chemical Society usually awards two prizes as part of its Division conference . One of the prizes is awarded to the best master's thesis and the other to the best dissertation in the field of the chemistry of construction materials . The Young Scientist Award is linked to an award certificate and is endowed with prize money of 1000 euros for the master's thesis and 3000 euros for the dissertation. A panel of experts decides on the selection with a simple majority of votes.

Young Scientist Award 2020

Dr. Elsa Qoku
M.Sc. Christopher Schiefer

The 2020 Young Scientist Award was presented to Dr. Elsa Qoku and M.Sc. Christopher Slate   awarded.

Dr. Elsa Qoku: In recognition of her dissertation entitled ?Characterization and quantification of crystalline and amporphous phase assemblage in ternary binders during hydration?. The central concern of the work is the deepening of the hydration mechanisms of ternary binders with special consideration of the role of X-ray amorphous phases. This work thus meets a current research topic in the chemistry of construction materials. It impresses with a strong methodological investigation, which follows the structure of the dissertation - chemical reaction - analysis - modeling - stringently. Ms. Qoku deals with very complex issues clearly, clearly and very easily. An excellent overview of the international literature as well as a very good reference to it during the evaluation characterize this work. A particular strength of the work is the methodological comparison between QXRD, NMR, TGA and stoichiometric calculations. The model concepts developed further by Ms. Qoku on the basis of her experimental results, flanked by thermodynamic modeling, are new for the hydration of binders rich in alumina cement. Overall, this dissertation significantly expands the knowledge about the temporal development of the hydrate phases in complex ternary systems. Therefore, the presented dissertation represents an outstanding scientific achievement.

Christopher Schiefer: In recognition of his master's thesis entitled ?Mg-Al-LDH-PCE nanocomposites as a hydration accelerator for cement?. The master thesis of Mr. Schiefer is dedicated to the synthesis, analysis and application of Layered Double Hydroxides (LDH) nanocomposites as hydration accelerators for cements such as Portland cement and calcium aluminate cement. With this topic, Mr. Schiefer encounters an important area of current chemical research in the chemistry of construction materials. Recognizing the fundamental relationships between the acceleration of cement hydration is a very important key to increasing the performance of cements and, as a result, reducing CO2 in cements, concrete, mortar and plasters. The comprehensive presentation of the literature is impressive, the derivation of the task is precise and logical. The synthesis experiments are very well thought out and skilfully carried out. The analytical methods are carefully selected and comprehensive, the application-oriented tests in the mortar round off the experimental work. The entire work is also very successful in its form and design as well as the representations. All in all, Mr. Schiefer is presenting an extremely productive and worthy master?s thesis.

Miss Dr. Ellina Bernhard, Empa, Dübendorf (Switzerland) received the Young Scientist Award 2018 in recognition of her dissertation on the topic:

"Magnesium silicate hydrate (MSH) characterization: temperature, calcium, aluminum and alkali"

The focus of the work is magnesium silicate hydrate, its formation and interaction with calcium, aluminum and alkali ions. Ms. Bernard is working on missing thermodynamic data for MSH structures in her dissertation. For the first time, these form a broad basis for modeling the MSH structures. The work is very well structured, the system is impressive. The extensive analysis, which is methodically coordinated and perfectly complements each other, is impressive. The detailed interpretation remains focused and is accompanied by very well structured summaries and very good "main findings". The chemistry of the magnesium silicate hydrate structures is rather limited to special applications and areas of use. However, this work is a scientifically excellent achievement and it can be expected that the knowledge gained here will also have an impact on the chemistry of construction materials . A great contribution to the understanding of the MSH system was made here.

Dr.-Ing. Henning-Felix von Daake, Technische Universität Berlin, received the Young Scientist Award 2018 in recognition of his dissertation on the topic:

"Possibilities for optimizing the mode of action of construction chemical additives through mechanisms of the controlled release of active ingredients"

The work takes up the problem of the development of drug concentrations over time. This is often not tailored to the prevailing conditions and the use is therefore not effective. Mr. von Daake addresses this problem through encapsulation and controlled release. Despite the extensive utilization of the results, the work is written as a monograph. The work is to be regarded as highly innovative because it was consistently designed and carried out in an interdisciplinary manner. It should be emphasized that Mr. von Daake had to use some methods (encapsulation, release) to solve the problem, for which he, as a trained civil engineer, lacked both the theoretical and the practical basics. However, he mastered this with flying colors. All in all, he succeeded in transferring an approach from other disciplines in an original way to solving a common practical building problem. An excellent performance with clear practical relevance.

The award ceremony took place as part of the chemistry of construction materials Conference on October 1, 2019 in Aachen.
