Researchers at Kyushu University have developed a photocatalytic system that can selectively capture reacting molecules and hold them close to the active sites that absorb energy from light. This innovation addresses a long-standing challenge of having the photocatalyst maintain
Researchers at Kyushu University have developed a photocatalytic system that can selectively capture reacting molecules and hold them close to the active sites that absorb energy from light. This innovation addresses a long-standing challenge of having the photocatalyst maintain a high reaction rate even when the reacting molecules are present at very low concentrations.

Light-controlled brake makes random molecular motion 300,000 times slower
Molecules are never still. Driven by thermal energy, they are constantly moving through space, while their individual parts also rotate relative to one another. Scientists at IOCB Prague have now shown that random motion within a molecule can be dramatically suppressed. Using lig

A 'simple recipe' takes some of the guesswork out of mass spectrometry imaging
A small sample of human tissue can hold a remarkable amount of information. Researchers can use it to search for molecular clues associated with cancer, investigate the chemical landscape of the brain or determine where a drug travels after it enters the body. Mass spectrometry i

Open database tracks Earth's water cycle by standardizing decades of satellite data
All water comes from somewhere. Researchers who want to know where it comes from rely on water isotopes, variants of water molecules with slightly different masses, as location identifiers. In particular, the specific ratio of heavy to light water isotopes is unique to the water'
