CO2 is the most important greenhouse gas responsible for global warming. It is released to the atmosphere mainly due to the combustion of fossil fuels used for mobility and industrial processes. In recent years, electrochemical reduction of CO2 has raised as a promising route to convert CO2 in value added chemicals such as carbon monoxide, […]

Photocatalysis can be defined as the change in the rate of chemical transformation in the presence of light, assisted by a catalyst that is capable of absorbing light and turn it into a useful energy source. Heterogeneous photocatalysis employ semiconductor materials (mainly transition metal oxides), this technology has found important applications such as water splitting

Malaysia is one of the major producers and exporters of Crude Palm Oil, producing roughly 31% of world\’s production. Over 5 million hectares are being utilized and the Palm Oil industry contributes 8% of Malaysia\’s Gross National Income. As such, it is one of the critical industries for the livelihood of Malaysians. This industry also leaves behind to the tune of 100 million dry tons of Oil Palm Waste.

One of the key challenges facing any battery chemistry is energy density. How does one increase energy density without compromising on safety? While this is important for all batteries in general, this is even more important for micro batteries that are to power critical sensors and implanted device.

What if there is a blue print to help reverse global climate change? What can we do in our day to day life to help reduce carbon emissions? While these questions may prove to be at the scale of solving world hunger, Paul Hawken and team had taken a shot at answering these questions.

Be it an energy generating cell or an energy consuming cell, efficiency of an electrochemical cell has traditionally been looked at as a product of voltage efficiency and current efficiency. Voltage efficiency takes care of the impact of ohmic losses in electrode and electrolyte, polarization losses at the electrode due to charge transfer reaction and polarization losses due to mass transfer limitations. Current efficiency takes care of the impact of parasitic reactions and the effective utilization of reactants. Can there be additional energy loss leading to efficiency loss that is not captured in either via voltage or via current efficiency?

Electrochemical machining at one point was termed “Action at a distance”. Now there is truly an electrochemical action being designed, where in we can carry out an electrochemical process on a conductive substrate without ever connecting an electrical lead. Yes, recent research and investigations on bipolar electrochemistry makes this possible.

One of the key application areas of electrochemistry is in the field of Sensors. There have been several different gas sensors developed using electrochemical principles. The sensors can either be potentiometric, meaning measuring voltage as a response to varying gas concentration or be amperometric, meaning measuring current as a response to varying gas concentration.
