Elemental sulfur coarsening kinetics [PDF]

, 2014
BACKGROUND: Elemental sulfur exists is a variety of forms in natural systems, from dissolved forms (noted as S8(diss) or in water as S8(aq)) to bulk elemental sulfur (most stable as α-S8).

A Bifunctional Fibrous Scaffold Implanted with Amorphous Co2P as both Cathodic and Anodic Stabilizer for High‐Performance Li─S Batteries

Advanced Science, EarlyView.
An amorphous Co2P‐embedded porous carbon nanofiber membrane (A─Co2P/PCNF) via electrospinning/in situ phosphorization is developed to serve as the dual‐electrode stabilizer for Li─S batteries. The amorphization strategy enables more exposed undercoordinated Co sites with optimized d‐band centers, enhanced LiPSs adsorption/catalysis, and lithiophilicity‐

Balancing surface adsorption and diffusion of lithium-polysulfides on nonconductive oxides for lithium–sulfur battery design

Nature Communications, 2016
Metal oxides can suppress detrimental polysulfide shuttling in lithium-sulfur batteries, however selection criteria for oxide materials are still lacking.

Elucidating the electrochemical activity of electrolyte-insoluble polysulfide species in lithium-sulfur batteries [PDF]

, 2016
The direct synthesis of Li2 S2 , a proposed solid intermediate in the discharge of lithium-sulfur (Li-S) batteries, was accomplished by treating elemental lithium with sulfur in liquid ammonia at -41?? C.

Nanomedicine‐Driven Modulation of Reductive Stress for Cancer Therapy

Advanced Science, EarlyView.
This article introduces a novel therapeutic paradigm that deliberately induces reductive stress within tumor cells to exploit their unique biochemical vulnerabilities. It systematically reviews the underlying biological mechanisms, current detection and monitoring techniques, and emerging advanced nanotechnology platforms specifically designed to ...

Adaptive Catalytic Nanointerfaces for Controlled Hydrogen Evolution: an in Situ Electrochemical Approach

Advanced Science, EarlyView.
The ability to switch the HER activity of precious metals at will through a reconfigurable step‐edge/nanoparticle interface, using sulfur as an inorganic mediator, is demonstrated for the first time. This methodology addresses the durability issue of highly catalytic precious metals, which are typically single‐use, thereby extending their lifespan ...

TRPA1 Ion Channel Determines Beneficial and Detrimental Effects of GYY4137 in Murine Serum-Transfer Arthritis

Frontiers in Pharmacology, 2019
Modulation of nociception and inflammation by sulfide in rheumatoid arthritis and activation of transient receptor potential ankyrin 1 (TRPA1) ion channels by sulfide compounds are well documented.

In situ wrapping of the cathode material in lithium-sulfur batteries

Nature Communications, 2017
To suppress the polysulfide shuttling effect in Li-S batteries, here the authors report a carbon/sulfur composite cathode with a wrapping layer that overcomes the trade-off between limiting polysulfide diffusion and allowing electrolyte infiltration, and

Evaluation of a metering, mixing, and dispensing system for mixing polysulfide adhesive [PDF]

Tests were performed to evaluate whether a metered mixing system can mix PR-1221 polysulfide adhesive as well as or better than batch-mixed adhesive; also, to evaluate the quality of meter-mixed PR-1860 and PS-875 polysulfide adhesives.

Lithium Sulphur Batteries [PDF]

, 2015
S+C cathode material was prepared by simple solid-state reaction in ball mill. Content of sulphur was approximately 80 wt. % in final sample. Cyclic voltammetry and galvanostatic charge/discharge techniques were used for characterization of the samples ...
