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...

Chemists discover key to early Earth chemistry, which could unlock ways to speed up chemical synthesis for drug discovery. Purdue University chemists have uncovered a mechanism for peptide-forming reactions to occur in water — something that has puzzled scientists for decades.

“This is essentially the chemistry behind the origin of life,” said Graham Cooks, the Henry Bohn Hass Distinguished Professor of Analytical Chemistry in Purdue’s College of Science...

The technology, which has been tested in the lab, could ultimately be used for manufacturing and building in difficult-to-access or dangerous locations such as tall buildings or help with post-disaster relief construction, say the researchers.

3D printing is gaining momentum in the construction industry. Both on-site and in the factory, static and mobile robots print materials for use in construction projects, such as steel and concrete structures.

This new approach to 3D printing – led in its development by Imperial and Empa, the Swiss Federal Laboratories of Materials Science and Technology – uses flying robots, known as drones, that use collective building methods inspired by natural ...
