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 ...

New scale for electronegativity rewrites the chemistry textbook

Electronegativity is one of the most well-known models for explaining why chemical reactions occur. Now, Martin Rahm from Chalmers University of Technology, Sweden, has redefined the concept with a new, more comprehensive ...

Quantum chemistry on quantum computers

Quantum computing and quantum information processing technology have attracted attention in recently emerging fields. Among many important and fundamental issues in science, solving the Schroedinger equation (SE) of atoms ...

Chemical bond versus electromagnetic waves

Vibrating carbon monoxide molecules adsorbed at the surface of a salt crystal stop moving after a few milliseconds. Scientists now discovered this is dominantly due to the emission of electromagnetic waves. The role of the ...

Carbon dioxide as a raw material

Researchers at the Ruhr-Universität Bochum have found a way to turn climate-damaging CO2 into an alcohol that could serve as a raw material for the chemical industry without producing large amounts of salt waste. The reaction ...

Supercomputing more light than heat

Solar cells can't stand the heat. Photovoltaics lose some energy as heat in converting sunlight to electricity. The reverse holds true for lights made with light-emitting diodes (LED), which convert electricity into light. ...

A bacterial powder for quickly stabilizing gravel surfaces

EPFL's Laboratory of Soil Mechanics has developed an easily reproducible technique using bacteria and urea to reinforce sandy or gravelly terrain. A series of chemical reactions lead to the rapid formation of mineral crystals ...
