Scientists discover that charcoal traps ammonia pollution

Cornell University scientists Rachel Hestrin and Johannes Lehmann, along with collaborators from Canada and Australia, have shown that charcoal can mop up large quantities of nitrogen from the air pollutant ammonia, resulting ...

Crystal clear solvent filtration

Covalent organic materials with well-ordered porous microstructures could provide the membranes needed for technology to meet increasingly stringent environmental controls and be cost effective to produce.

Scientists analyze the chemical bonds that shape proteins

An international group of scientists including visiting foreign professor from RUDN University Kamran Makhmudov has analyzed chemical bonds in proteins based on sulfur and other elements from the 16th group of the periodic ...

How selenium compounds might become catalysts

Chemists at Ruhr-Universit├Ąt Bochum have tested a new approach for activating chemical reactions based on the element selenium. They demonstrated that selenium can form bonds similar to those of hydrogen bonds, resulting ...

New class of 'soft' semiconductors could transform HD displays

A new type of semiconductor may be coming to a high-definition display near you. Scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that a class of semiconductor called ...
