Spit-powered microbial fuel cell developed to power biosensors in remote regions

The battery is designed to be used in extreme conditions where normal batteries don’t function and although it only generates a relatively small amount of electricity, it is enough to power devices such as biosensors. Professor Seokheun Choi, who developed the battery, has…

Engineers pioneer platinum shell formation process, achieve first-ever observation

UCI researchers have devised a new method of dynamically forming a platinum shell on a metallic alloy nanoparticle core, a development that may lead to better materials for oxygen reduction reactions in fuel cells that power some cars and electronic devices. In a…

New Mazda combustion engine could fill the gap before electric vehicle ubiquity

The compression ignition engine is 20 to 30 per cent more fuel efficient than the Japanese automaker’s current engines and uses a technology that has eluded the likes of Daimler and General Motors. Mazda, with a research and development (R&D) budget a fraction…

Stable and metallic two-dimensional TaC2 as an anode material for lithium-Ion battery

J. Mater. Chem. A, 2017, Accepted ManuscriptDOI: 10.1039/C7TA04390B, PaperTong Yu, Shoutao Zhang, Fei Li, Ziyuan Zhao, Lulu Liu, Haiyang Xu, Guochun YangRelative to advanced cathode materials, the anode materials become one of the key factors to hamper the performance improvement of lithium-ion batteries…

High Energy and High Power Lithium-Ion Capacitors Based on Boron and Nitrogen Dual-Doped 3D Carbon Nanofibers as Both Cathode and Anode

High energy density at high power density is still a challenge for the current Li-ion capacitors (LICs) due to the mismatch of charge-storage capacity and electrode kinetics between capacitor-type cathode and battery-type anode. In this work, B and N dual-doped 3D porous carbon…
