Boosting Photoelectrochemical Water Splitting by TENG-Charged Li-Ion Battery

The need for cost-effective and sustainable power supplies has spurred a growing interest in hybrid energy harvesting systems, and the most elementary energy production process relies on intermittent solar power. Here, it is shown how the ambient mechanical energy leads to water splitting…

Enhanced Electrocatalysis for Energy-Efficient Hydrogen Production over CoP Catalyst with Nonelectroactive Zn as a Promoter

As a non-toxic species, Zn fulfills a multitude of biological roles, but its promoting effect on electrocatalysis has been rarely explored. Herein, the theoretic predications and experimental investigations that nonelectroactive Zn behaves as an effective promoter for CoP-catalyzed hydrogen evolution reaction (HER) in…

A battery-inspired strategy for carbon fixation

Scientists working toward the elusive lithium-air battery discovered an unexpected approach to capturing and storing carbon dioxide away from the atmosphere. Using a design intended for a lithium-CO2 battery, researchers in Japan and China have developed a way to isolate solid carbon dust…

Lithium-Ion Batteries: One-to-One Comparison of Graphite-Blended Negative Electrodes Using Silicon Nanolayer-Embedded Graphite versus Commercial Benchmarking Materials for High-Energy Lithium-Ion Batteries (Adv. Energy Mater. 15/2017)

In article number 1700071, Jaephil Cho, Minseong Ko, and co-workers report a rational comparison of graphite-blended Si anodes with Si nanolayer-embedded graphite and industrially developed benchmarking materials. The Si nanolayer-embedded graphite exhibits superior compatibility with conventional graphite to the benchmarking materials, offering the…

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…
