Graphene-Metal Oxide based Nanocomposites for Supercapacitor Applications

Selvakumar D., Nagaraju P., Jayavel R., Anna University, IN

Two dimensional graphene-based nanocomposites have been synthesized through the modified Hummer’s method and chemical reduction process. Transition metal oxides were decorated on the graphene sheets by in-situ hydrothermal method. The composites were formed with graphene [...]

Experimental investigation on solidification behavior of water based CNT nanofluids for cool thermal storage system

Kumaresan V., Anna University, IN

Nano-enhanced phase change material (NEPCM) was prepared by two step method using distilled water as the base fluid, sodium dodecyl benzene sulphonate (SDBS) as a surfactant, pseudomonas as nucleating agent and multi-walled carbon nanotubes (MWCNT) [...]

Study of Well Barrier Hole Burning in Quantum Well Bistable Lasers

Ganesh Madhan M., Vaya P.R., Gunasekaran N., Anna University, IN

Quantum carrier capture and release effects on optical bistability in multiple quantum well (MQW) lasers are studied using the well barrier hole burning model. The ratio of carrier capture to release time (h) is varied [...]

Circuit Simulation of Quantum Well Bistable Laser Diodes

Madhan M.G., Vaya P.R., Gunasekaran N., Anna University, IN

A large signal electrical equivalent circuit for the multi quantum well bistable laser diode has been developed from the rate equations. The dc and transient analysis are carried out using PSPICE circuit simulator. It is [...]
