CuCo2S4 nanoparticles demonstrating outstanding electrochemical performances were firstly synthesized through a simple solvothermal approach without using any templates. CuCo2S4 synthesized in glycerol (CuCo2S4-glycerol) fulfills an ultrahigh capacitance of 5030 F g(-1) at 20 A g(-1) in a polysulfide electrolyte.

Sulfonic acid-incorporated-MCM-41 mesoporous materials prepared using a silane containing tetrasulfide linkages showed exceptional yields of the acetylated product in the acetylation of anisole due to their high content of strong acid sites.

In this research work, the effect of three (3) pulping additives such as polysulfide, Anthraquinone and surfactant used in monoethanolamine (MEA) agro-biomass, their possible interactions synergy on pulp screened yield were investigated. The conditions digester adjusted so that experimental design considered following factors levels: 75% MEA charge, 150oC cooking temperature, 90minutes time, 4 ...

A light-weight, high specific surface current collector made of vertically-aligned carbon nanotubes grown on an aluminum substrate was fabricated and studied as a positive electrode in a semi-liquid lithium/polysulfide battery. This simple system delivered stable capacities over 1000 mA h gS(-1) and 2 mA h cm(-2) with almost no capacity loss over 50 cycles.

Herein, we report a cheap and simple approach to solve the polysulfide dissolution problem in lithium sulfur batteries. It was interestingly revealed that a simple insertion of acetylene black mesh enabled us to obtain the capacity of 1491 mA h g(-1) at initial discharge and 1062 mA h g(-1) after 50 cycles.

An enzyme system in rat liver catalyzes the decomposition of mercaptopyruvate to pyruvate and sulfur (1). At the optimal pH of this system, this reaction has been shown to be a transsulfuration (2). Acceptors of the sulfur include cyanide (2), sulfite and sulfinates (3). In the absence of an acceptor, the sulfur is fixed in a reactive form which decomposes to free sulfur at lower pH. This repor...
