Low‐Bandgap Se‐Deficient Antimony Selenide as a Multifunctional Polysulfide Barrier toward High‐Performance Lithium–Sulfur Batteries

Advances in Materials, 2019
The shuttling behavior and sluggish conversion kinetics of the intermediate lithium polysulfides (LiPSs) represent the main obstructions to the practical application of lithium–sulfur (Li–S) batteries.

Mesoporous manganese-selenide microflowers with enhanced electrochemical performance as a flexible symmetric 1.8 V supercapacitor

, 2020
Single-phase hierarchical manganese selenide (α-MnSe) microflowers assembled by nanosheets were synthesized through a facile-solvothermal strategy and applied for symmetrical supercapacitor’s electrode material for the first time. The α-MnSe microflowers

Metabolism of Hydrogen Selenide and Methylated Selenides

1979
Inorganic forms of selenium are readily metabolized to a variety of or-ganoselenium compounds in microorganisms, plants, and animals. The metabolism of selenium may either enhance or reduce the biological activity of this element. Nutritionally active inorganic selenium compounds, such as sodium selenite or sodium selenate, can be converted to ...

Zinc Selenide Optical Fibers

Advanced Materials, 2011
Semiconductor waveguide fabrication for photonics applications is usually performed in a planar geometry. However, over the past decade a new field of semiconductor-based optical fiber devices has emerged. The drawing of soft chalcogenide semiconductor glasses together with low melting point metals allows for meters-long distributed photoconductive ...

Optical gain in gallium selenide and indium selenide

Physica B+C, 1981
Abstract The stimulated emission at 80 K from layered single crystals of GaSe and InSe has been studied at high excitation density by means of nitrogen and dye laser, respectively. On both the semiconductors we observe the stimulated emission associated with exciton-exciton scattering.

Acute Hydrogen Selenide Inhalation

Chest, 1980
Acute exposure to selenium hydrochloride resulted in severe dyspnea and a pneumomediastinum in a young healthy man. Pulmonary function tests revealed restrictive and obstructive airways disease. Although the patient's pulmonary function slowly improved, subsequent studies revealed persistent impairment.

Thallium selenide infrared detector

Applied Optics, 1977
The application of semiconducting thallium selenide for ir detection is described. A responsivity of 10(6) V/W and NEP of the order of 10(-15) W/ radicalHz with a response time of 3 msec can be obtained by operating the detector at 1.5 K.
