Time-resolved ARPES makes it possible to directly visualize the band dispersion of photoexcited solids, as well study its time evolution on femtosecond scale. In this article, we show how technique can be used monitor ultrafast hot carrier dynamics and conduction in two typical monochalcogenide semiconductors: direct gap, n-type indium selenide indirect p-type germanium selenide. With approach,...
We present, for the first time, versatile solutions of concentrated selenium, within an array of amines, in a fast and low temperature manner without contaminants. These solutions allow the unprecedented opportunity to synthesize a variety of pure selenium and selenide nanoparticles as well as mixed chalcogen sulfoselenide compounds.
In the first, cadmium selenide nanoparticles loaded on activated carbon (CdSe-NP-AC) has been synthesized. Then, this new adsorbent successfully has been applied for the removal of fluoride from aqueous solution in batch studies, while the effect of various experimental parameters like initial pH, contact time and temperature on its removal percentage was examined by one at a time optimization ...
Syntheses of several diorganodiselenides and, in particular, a seven-membered cyclic seleninate ester derived from 2-phenoxyethanol are described. The seleninate ester was obtained from allyl (2-(2-hydroxyethoxy)phenyl) selenide through a series of oxidation and [2,3] sigmatropic rearrangement steps. The ester exhibits good GPx-like activity in the coupled reductase assay.
Metal selenide nanocrystals have attracted attention as promising materials in photovoltaics and thermoelectrics. However, the expensive labor-intensive synthesis methods utilized for produ...
