Visible light photocatalytic H(2) production from water splitting is of great significance for its potential applications in converting solar energy into chemical energy. In this study, a series of Zn(1-x)Cd(x)S solid solutions with a nanoporous structure were successfully synthesized via a facile template-free method at room temperature. The obtained solid solutions were characterized by X-ray...

Isolated silkgland ribosomes were irradiated with X-rays, and their activities to synthesize fibroin in vitro were examined. A marked decrease in their activities was observed when ribosomes were incubated at 37•Ž following X-irradiation. Per cent decrease in the ribosomal activity leveled off at 37•Ž after 30 minutes incubation . The extent of decrease was dependent on X-ray dose. Treatment of...

In this work we used inelastic X-ray scattering to study the high-pressure behavior of H2O. At lower pressures and low temperatures, X-ray Raman spectroscopy (XRS) is used for investigating water, ice Ih, ices II and IX. At higher pressures we discovered new radiation chemistry in the H2O system. A new compound composed of molecular oxygen and hydrogen was formed after X-ray irradiation of the ...

In this study we present details of a portable system which contains an X-ray source and heater, designed to irradiate and heat samples within a quartz glass tube for electron spin resonance (ESR) dating. The spatial distribution of the X-ray beam was measured with a radiation sensitive film and the images were scanned and mapped using the Risoescan software. The reproducibility of irradiations...
