How fine bubbles lead to more efficient catalysts

Newly discovered effect boosts productivity of green hydrogen transport processes

21-Nov-2022 - Catalysts are of utmost relevance for the production of chemicals and energy storage with hydrogen. Researchers at the Helmholtz Institute Erlangen-Nürnberg for Renewable Energy (HI ERN) and Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have now discovered that the formation of bubbles ...

In simulation of how water freezes, artificial intelligence breaks the ice

AI techniques enable Princeton researchers to simulate ice formation with quantum accuracy

11-Aug-2022 - A team based at Princeton University has accurately simulated the initial steps of ice formation by applying artificial intelligence (AI) to solving equations that govern the quantum behavior of individual atoms and molecules. The resulting simulation describes how water molecules transition into ...

Revolutionary images of the birth of crystals

A team from the UNIGE has succeeded in visualizing crystal nucleation - the stage that precedes crystallization - that was invisible until now

26-Apr-2022 - At the interface between chemistry and physics, the process of crystallization is omnipresent in nature and industry. It is the basis for the formation of snowflakes but also of certain active ingredients used in pharmacology. For the phenomenon to occur for a given substance, it must first go ...

It takes some heat to form ice

Findings turn previous understanding of ice formation upside down

31-May-2021 - Researchers from TU Graz in Austria and the Universities of Cambridge and Surrey succeeded to track down the first step in ice formation at a surface, revealing that additional energy is needed for water before ice can start to form. Water freezes and turns to ice when brought in contact with a ...
