A world record in detecting extremely low levels of gas impurities

Photoacoustic spectroscopy applied to background-free analyses was used to measure unprecedentedly small trace gas concentrations. Teemu Tomberg from the University of Helsinki developed detection methods that make it possible ...

Water splitting observed on the nanometer scale

It is a well-known school experiment: Applying a voltage between two electrodes inserted in water produces molecular hydrogen and oxygen. Researchers seek to make water splitting as energy-efficient as possible to advance ...

Scientists reveal infrared spectroscopy of neutral water dimer

A research team led by Profs. Jiang Ling, Yang Xueming and Zhang Donghui from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences, in collaboration with Prof. Li Jun from Tsinghua University, ...
