Novel mixed nickel/cobalt hexacyanoferrate microcubes with synergistic effects for aqueous hybrid supercapacitors.

Combining different metals in coordination compounds is an efficient strategy to improve their various properties. Herein, mixed nickel-cobalt hexacyanoferrate (NiCoHCF) microcubes of varying  :  molar ratios are synthesized a co-precipitation route and comprehensively characterized to study their material and electrochemical properties. NiCoHCF microcubes display the battery-type electrochemical energy storage mechanism in aqueous electrolytes.

Preparation of Gold Nanoparticles Deposited Silicon Thin Film Electrode by Self-Assembly Method for the Employment of an Anode Material for Lithium Secondary Batteries.

This work describes a self-assembly method of gold nanoparticles coating on the surface of silicon thin films for the anode material of lithium secondary batteries. The preparation of the silicon thin films was carried out by electron cyclotron resonance metal organic chemical vapor deposition (ECR-MOCVD) process. The obtained films were further coated with (3-aminopropyl)-trimethoxysilane (APTMS) which has a role to bind the oxygen functional groups on Si surface and the gold nanoparticles.
