Surface modification of nanocrystalline LiCoO2 particles with rare earth oxides using polymeric resin process

Nageswara Raoa B., Venkateswarlub M., Satyanarayana N., Pondicherry University, IN

Among the available positive electrode materials, layer structured LiCoO2 is the most preferred one in commercial Li-ion batteries. However, LiCoO2 exhibits a capacity fading at high rates due to its structural instability and reactivity with [...]

CO, CO2 and CH4 Gas Adsorption (Pure and Binary) on Cu-BTC and MIL-101 Metal Organic Frameworks (MOFs)

Chowdhury P., National Institute of Technology Rourkela, IN

Here, we present a comparative study on gas adsorption of CO, CO2 and CH4 on two of the most versatile MOFs reported till date: Cu-BTC (or, HKUST-1) and MIL-101 (or, Cr-BDC). The high pressure (0-100 [...]
