Porous nickel oxide films were prepared by electrochemically precipitating nickel hydroxide and heating the hydroxide in air at 300°C. The resulting nickel oxide films behave as an electrochemical capacitor with a specific capacitance of 59 Flg electrode material. These nickel oxide films maintain high utilization at high rates of discharge (i.e., high power density) and have excellent cycle li...

Investigation of the redox properties of drugs and their determination are performed by electrochemical techniques. Data obtained from electrochemical techniques are often correlated with molecular structure and pharmacological activity of drugs. In this regard, different modified electrodes were applied as sensors for quantification of different drugs.A nanocomposite of reduced graphene oxide-...

Fischer-Tropsch synthesis (FTS) is normally carried out with either a cobalt or iron-based catalyst depending on the ratio of H2/CO in the feed. As a step in gas-to-liquids (GTL) technology, cobalt catalysts are often preferred [1,2] due to the low intrinsic water-gas shift (WGS) activity of cobalt. While in many typical supported-metal catalysts, a low metal loading is preferable for obtaining...

Encapsulating cobalt oxide particles in flexible “macroreactor” chitosan spheres prevents catalyst degradation during hydrogen generation.

Alkaline Water Splitting In article number 2301405, Ravichandar Babarao, Seunghyun Lee, and co-workers demonstrate excellent bifunctional activity for water-splitting from metal-organic framework derived boron-doped cobalt-oxide/Cobalt metal@N-doped carbon 3D mesoporous heterostructures grown vertically on Ni foam substrate. The synergistic effect between boron doping the modulated cobalt oxida...

Single-crystalline cobalt silicide/SiO(x) nanocables have been grown on Co thin films on an SiO(2) layer by a self-catalysis process via vapor-liquid-solid mechanism. The nanocables consist of a core of CoSi nanowires and a silicon oxide shell with a length of several tens of micrometers. In the confined space in the oxide shell, the CoSi phase is stable and free from agglomeration in samples a...

The paper reports correlation between processing, structural and magnetic properties of cobalt nanoparticles dispersed in an insulating oxide matrix. High-temperature, chemical decomposition approach was utilized to achieve highly-dispersed, ultra-fine cobalt nanoparticles in silica matrix. Synthesis parameters such as precursor to passivating agent ratio were designed to control the metal-to-o...
