Researchers develop new technique that charges EV battery in just 10minutes. The record-breaking combination of a shorter charge time and more energy acquired for longer travel range was announced today (Oct. 12) in the journal Nature.

“The need for smaller, faster-charging batteries is greater than ever,” said Chao-Yang Wang, the William E. Diefenderfer Professor of Mechanical Engineering at Penn State and lead author on the study. “There are simply not enough batteries and critical raw materials, especially those produced domestically, to meet anticipated demand.”

One of the leading causes of water pollution is heavy metal contamination which has profound adverse effects on human health and the environment. That’s why Clarkson University researchers have developed a cost-effective, 3D printing technology to create sustainable bio-based adsorbents that can effectively remove toxic heavy metal ions from contaminated environments. The 3D printing technique offers a cost-effective, scalable and simple approach to creating tunable adsorbents for environmental remediation that can be used broadly by the community for environmental remediation and sensing applications.

The work performed in the laboratory of Professor Silvana Andreescu, the Egon Matijevic Chair in Chemistry, was recently featured on the front ...

A research team succeeds in developing anode-free Li batteries with maximized energy density, improving energy density by 40%. The number of newly registered electric vehicles (EVs) in Korea surpassed 100,000 units last year alone. Norway is the only other country to match such numbers. The core materials that determine the battery life and charging speed of now commonly seen EVs are anode materials. Korea’s domestic battery industry has been committed to finding revolutionary ways to increase the battery capacity by introducing new technologies or other anode materials. But what if we get rid of anode materials altogether?

Progress has been made on the path to sunlight-driven production of hydrogen. Chemists present a new enzyme-like molecular catalyst for water oxidation. Humankind is facing a central challenge: it must manage the transition to a sustainable and carbon dioxide-neutral energy economy.

Hydrogen is considered a promising alternative to fossil fuels. It can be produced from water using electricity. If the electricity comes from renewable sources, it is called green hydrogen. But it would be even more sustainable if hydrogen could be produced directly with the energy of sunlight.

In nature, light-driven water splitting takes place during photosynthesis in plants...
