Optimizing electric fields yields better catalysts

Industries rely on catalysts. These materials lessen the energy used in refining oil, manufacturing plastics, and much more. Catalysts can also mean less waste is produced. Better catalysts would benefit industries and the ...

Chemists solve persistent problem after four decades

After almost four decades, Leiden and Eindhoven chemists have resolved the discussion about the correct model regarding the simplest chemical reaction in heterogeneous catalysis, which is essential for fuel cells. Using a ...

Chemists disprove the universal nature of the mercury test

The mercury test of catalysts that has been used and considered universal for 100 years turns out to be ambiguous. This conclusion was reached by a group of scientists including a RUDN chemist. The group confirmed that the ...

On the expansion threshold of a species' range

What stops a species adapting to an ever-wider range of conditions, continuously expanding its geographic range? The biomathematician Jitka Polechová, an Elise Richter Fellow at the University of Vienna, has published a ...

Rolling dice for cell size specification in plant leaf epidermis

One of the central questions in biology is how a cell specifies its size. Because size distribution often shows a characteristically skewed pattern in a tissue, there may be some stochastic option for determining cell size. ...
