Water world

21-Nov-2017

Researchers at Washington University in St. Louis have traced the paths of three water channels in an ancient photosynthetic organism to provide the first comprehensive, experimental study of how that organism uses and regulates water to create energy. Photosynthesis is the chemical conversion of ...

Artificial intelligence for obtaining chemical fingerprints

Neural networks carry out chemical simulations in record time

28-Sep-2017

Researchers at the Universities of Vienna and Göttingen have succeeded in developing a method for predicting molecular infrared spectra based on artificial intelligence. These chemical "fingerprints" could only be simulated by common prediction techniques for small molecules in high quality. With ...

A more complete picture of the nano world

28-Aug-2017

They may be tiny and invisible, says Xiaoji Xu , but the aerosol particles suspended in gases play a role in cloud formation and environmental pollution and can be detrimental to human health. Aerosol particles, which are found in haze, dust and vehicle exhaust, measure in the microns. One micron ...
