Jan 04, 2023 (Nanowerk News) A device that can harvest water from the air and provide hydrogen fuel—entirely powered by solar energy—has been a dream for researchers for decades. Now, EPFL chemical engineer Kevin Sivula and his team have made a significant step towards bringing this vision closer to reality....

Jan 04, 2023 (Nanowerk News) The precise control of micro-mechanical oscillators is fundamental to many contemporary technologies, from sensing and timing to radiofrequency filters in smartphones. Over the past decade, quantum control of mechanical systems has been firmly established with atoms, molecules, and ions in the first wave of development...

Jan 04, 2023 (Nanowerk News) As semiconductor devices become ever smaller, researchers are exploring two-dimensional (2D) materials for potential applications in transistors and optoelectronics. Controlling the flow of electricity and heat through these materials is key to their functionality, but first we need to understand the details of those behaviors...

Jan 04, 2023 (Nanowerk News) More and more products contain nanoparticles: very small particles on the scale of 1-100 nanometres. Although they are impossible to see with the human eye, they can have a big effect. 'Nanomaterials are in many more products than you would expect,' Brinkmann says. 'To keep...

Jan 04, 2023 (Nanowerk News) Perovskite solar cells degrade when exposed to sunlight, which results in decreasing performance over time. A new research project will examine how such solar cells could recover and self-repair at night. "Electronic components, such as solar cells and LEDs, are made from semiconductor materials," says...

Jan 04, 2023 (Nanowerk News) Adding salt to a road before a winter storm changes when ice will form. Researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have applied this basic concept to develop a new method of heating and cooling. The technique, which they have...
