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 ...

Near-infrared photoactivatable oxygenation catalysts of amyloid peptide

20-Mar-2018

A new, biocompatible photooxygenation catalyst that can selectively oxygenate and degrade the pathogenic aggregation of Alzheimer's disease (AD)-related amyloid-β peptide (Aβ) under near-infrared (NIR) light irradiation is developed. The catalyst was able to oxygenate Aβ embedded under the skin ...
