Cage with Caps: Selective confinement of rare-earth-metal hydrates in host molecules
24-Aug-2022
Rare-earth metals are indispensable for many technical products, from smartphones, laptops, batteries, electromotors, and wind turbines, to catalysts. In the journal Angewandte Chemie, a Japanese team has now introduced a molecular “cage” with “caps” that can be used to selectively “confine” ...

Ultrafast charge transfer in Prussian blue analogues
23-Aug-2021
Photoinduced charge transfers are an interesting electronic property of Prussian blue and some analogously structured compounds. A team of researchers has now been able to elucidate the ultrafast processes in the light-induced charge transfer between iron and manganese in a manganese-containing ...
Sustainable chemical synthesis with platinum
A new catalyst allows wood to replace petroleum in hydrocarbon synthesis
26-Apr-2021
Researchers used platinum and aluminum compounds to create a catalyst which enables certain chemical reactions to occur more efficiently than ever before. The catalyst could significantly reduce energy usage in various industrial and pharmaceutical processes. It also allows for a wider range of ...
'Butterfly-shaped' palladium subnano cluster built in 3-D
25-Feb-2019
Miniaturization is the watchword of progress. Nanoscience - building structures on the scale of a few atoms - has long been at the forefront of chemistry for some time now. Recently, researchers at The University of Tokyo developed the new strategy to construct the subnanosized metal aggregates, ...
Why gold-palladium alloys are better than palladium for hydrogen storage
11-Jul-2018
Materials that absorb hydrogen are used for hydrogen storage and purification, thus serving as clean energy carriers. The best-known hydrogen absorber, palladium (Pd), can be improved by alloying with gold (Au). New research led by The University of Tokyo Institute of Industrial Science explains ...
Polarized light: A simple route to highly chiral materials
11-May-2018
Chirality is at the heart of chemical research and much technology. For organic chemists, choosing between the left- and right-handed isomers of molecules is all part of a day's work. However, many solid materials also have enantiomeric forms, giving rise to a range of applications. Organic ...
3-D axon assemblies pave the way for drug discovery
30-Oct-2017
Axons are the structures through which neurons transmit information to other cells. In the body, they aggregate to form fascicles. Several technologies allow scientists to generate and study single axons in the lab, but none are effective at creating nerve fascicles. A collaboration between ...
Rabbits' detached retina 'glued' with new hydrogel
14-Mar-2017
A newly developed elastic gel administered in liquid form and shown to turn jellylike within minutes after injection into rabbits' eyes to replace the clear gelatinous fluid inside their eyeballs, may help pave the way for new eye surgery techniques, says an international team of researchers led ...
Researchers Watch Catalysts at Work
18-Aug-2016
Physicists at the University of Basel have succeeded in watching a silver catalyst at work for the first time with the aid of an atomic force microscope. The observations made during an Ullmann reaction have allowed the researchers to calculate the energy turnover and, potentially, to optimize ...
New synthetic technology for medicines and fine chemicals
17-Apr-2015
A University of Tokyo research group has succeeded in synthesizing (R)- and (S)-rolipram, the active component of a medicine, in high yield with high selectivity by a catalyzed flow fine synthesis instead of the traditional batch method used in the production of 99% of medicines.Professor Shu ...
