Radiation Protection at Synchrotron Radiation Facilities [PDF]

Radiation Protection Dosimetry, 2001
A synchrotron radiation (SR) facility typically consists of an injector, a storage ring, and SR beamlines. The latter two features are unique to SR facilities, when compared to other types of accelerator facilities. The SR facilities have the characteristics of low injection beam power, but high stored beam power.

Engineering a local acid-like environment in alkaline medium for efficient hydrogen evolution reaction

Nature Communications, 2022
While catalysts have intrinsic activities toward reactions, such performances often require further optimization. Here, authors engineer an acid-like environment in alkaline media by fine-tuning the reaction environment of platinum nanoparticles on oxide

Relation between the Co-O bond lengths and the spin state of Co in layered Cobaltates: a high-pressure study

Scientific Reports, 2017
The pressure-response of the Co-O bond lengths and the spin state of Co ions in a hybrid 3d-5d solid-state oxide Sr2Co0.5Ir0.5O4 with a layered K2NiF4-type structure was studied by using hard X-ray absorption and emission spectroscopies. The Co-K and the
