The speaker discussed two important applications of electrochemistry in Nanochemistry – Energy generation and Biosensors. He emphasized the need for cleaner energy to reduce dependence on fossil fuels. Fuel cells have become a subject of intense study in this respect. The hydrogen-oxygen fuel cell was considered as a case in point. Several challenges and solutions with respect to their use in t...

An efficient conversion of CO2 into valuable fuels and chemicals has been hotly pursued recently. Here, for the first time, we have explored a series of M12x12 nano-cages (M = B, Al, Be, Mg; X = N, P, O) for catalysis of CO2 to HCOOH. Two steps are identified in the hydrogenation process, namely, H2 activation to 2H*, and then 2H* transfer to CO2 forming HCOOH, where the barriers of two H* tran...

The catalytic hydrogenation of levulinic acid, a key platform molecule in many biorefinery schemes, into γ-valerolactone is considered as one of the pivotal reactions to convert lignocellulose-based biomass into renewable fuels and chemicals. Here we report on the development of highly active, selective and stable supported metal catalysts for this reaction and on the beneficial effects of meta...

We have studied the ignition of fuel sprays and simulated solid rocket fuels (SRF) by the photoignition of single wall carbon nanotubes (SWCNTs) with an ordinary camera flash. Our investigation includes the effect of solid additives such as aluminum nano-particles and solid oxidizers such as ammonium perchlorate (AP) on the photoignition characteristics. We have shown that by mixing CNT with ot...

We have studied the ignition of liquid fuel and certain solid fuels by the photoignition of single wall carbon nanotubes (SWCNTs). Our investigation includes the effect of solid additives such as aluminum nano-particles and solid oxidizers such as ammonium perchlorate (AP) on the photoignition characteristics. We have shown that by mixing CNT with other nanoparticles and powdered material, the ...

In the current scenario, biofuel production from microalgae is beneficial to sustainability. Recently, one of most pressing concerns has been finding cost-effective and environmentally friendly energy sources meet rising demands without jeopardizing environmental integrity. Microalgae provide a viable biomass feedstock for as global market biofuels rises. Biodiesel made usually regarded best na...
