Fish gills for low-cost electro-catalysts – BIO FUEL CELL
Part of: GS-III- S&T (PT-MAINS-PERSONALITY TEST)
Scientists at the Institute of Nano Science and Technology, Mohali, have recently come up with an efficient, low-cost electro-catalyst from fish gills that can help develop environmentally friendly energy conversion devices. This bio-inspired carbon nanostructure can help overcome the bottleneck in the realization of several renewable energy conversion and storage technologies such as fuel cell, biofuel cell, and metal−air battery. It could be utilized as next-generation nonprecious carbon-based electrocatalyst for energy conversion and storage applications.
A microbial fuel cell (MFC) is a bio-electrochemical systemthat drives an electric current by using bacteria and a high-energy oxidant such as O2, mimicking bacterial interactions found in nature. MFCs can be grouped into two general categories: mediated and unmediated. The first MFCs, demonstrated in the early 20th century, used a mediator: a chemical that transfers electrons from the bacteria in the cell to the anode. Unmediated MFCs emerged in the 1970s; in this type of MFC the bacteria typically have electrochemically active redox proteins such as cytochrome on their outer membrane that can transfer electrons directly to the anode. In the 21st century MFCs have started to find commercial use in wastewater treatment.
A biofuel cell uses living organisms to produce electricity. It may refer to:

India is now ranked 38th out of 139 nations in the Logistic Performance Index (LPI) 2023 of the World Bank. From its previous rankings of 44th in 2018 and 54th in 2014, this is a notable improvement. Earlier, the Logistics Ease Across Different States (LEADS) Report 2022 was published by the Ministry of Commerce and Industry. About Logi
Airports discovered more than 63% of this illegal gold. The Department of Revenue Intelligence recently conducted the Golden Dawn Operation across India, seizing 101.7 kg of illegal gold valued at Rs 51 crore. Despite the fact that India receives a legal import of about 800-1,000 tonnes of gold each year, the illicit market is thought to be
Both parties expressed satisfaction with the ongoing bilateral defence cooperation at the 8th India-Thailand Defence Dialogue, which was held in Bangkok, Thailand. Cultural ties and mutual cooperation that have been shaped by thousands of years of lasting historical and cultural ties characterise India and Thailand relations. Highlight
