Journal of The Electrochemical Society, Volume 164, …
With its high theoretical specific charge, silicon is a promising candidate as electrode additive to enhance specific charge of graphite electrodes for high-energy-density Li-ion batteries. We prepared Si/C composites by a two-step procedure: the ballmilling of silicon nanoparticles with a carbon precursor for homogenization, followed by a carbonization step.
In situ imaging of the conducting filament in a silicon …
Semi-metallic silicon nanocrystals with structural variations from the conventional diamond cubic form of silicon are observed, which likely accounts for the conduction in the filament. The growth and shrinkage of the silicon nanocrystals in response to different electrical stimuli show energetically viable transition processes in the silicon forms, offering evidence for the switching mechanism.

Pressure-dependent first-order phase transition, mechanical, elastic, and thermodynamical properties of cubic zinc blende to rock-salt structures in 3C silicon carbide (SiC) are presented. An effective interatomic interaction potential for SiC is formulated. The potential for SiC incorporates long-range Coulo, charge transfer interactions, covalency effect, Hafemeister and Flygare type short

The dependence of the activity on the concentration of DAU suggests that DAU forms a complex with Fe phthalocyanine. Based on this concentration-dependence and an HPLC (high performance liquid chromatography) analysis of DAU hydrolysis, it was shown that hydrolysis of DAU in an electrolyte solution does not significantly affect the electro-oxidation of DAU by a carbon-supported Fe …
