General description

Cobalt(II,III) oxide, also knownas tricobalt tetraoxide is a black antiferrimagnetic solid. Our Co3O4 is a powder with a particle size of <10 μm and a cobalt concentration between 71-74%. A high melting point of 895 °C (dec.) indicates that Co3O4 can with stand elevated temperatures without decomposing, making it suitable for high-temperature applications such as heterogeneous catalysis in industrial processes. Co3O4 is also widely used in the battery industry as a precursor to fabricate cathode materials, such as lithium cobalt oxide and lithium nickel manganese cobalt oxide, for Li-ion batteries.

Application


  • Synthesis of diphenylalanine/cobalt oxide hybrid nanowires and their application to energy storage.: This study demonstrates the synthesis of hybrid nanowires using diphenylalanine and cobalt oxide, highlighting their potential for enhancing energy storage capacities (Ryu et al., 2010).

In soil metal ecotoxicology research, dosing is usually performed with metal salts, followed by leaching to remove excess salinity. This process also removes some metals, affecting metal mixture ratios as different metals are removed by leaching at different rates. Consequently

Magnetism and magnetic materials have been of scientific interest for over 1,000 years. More recently, fundamental investigations have focused on exploring the various types of magnetic materials and understanding the magnetic effects created by electric currents.

Magnetic materials permeate numerous daily activities in our lives. They are essential components of a diversity of products including hard drives that reliably store information on our computers, decorative magnets that keep the shopping list attached to the refrigerator door, electric bicycles that speed our commute to work, as well as wind turbines for conversion of wind energy to electrical power.

Nanomaterials are considered a route to the innovations required for large-scale implementation of renewable energy technologies in society to make our life sustainable.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
