Jul 06, 2022 (Nanowerk News) If you switch a bit in the memory of a computer and then switch it back again, you have restored the original state. There are only two states that can be called "0 and 1". However, an amazing effect has now been discovered at TU...

Physicists see electron whirlpools for the first time

Jul 06, 2022 (Nanowerk News) Though they are discrete particles, water molecules flow collectively as liquids, producing streams, waves, whirlpools, and other classic fluid phenomena. Not so with electricity. While an electric current is also a construct of distinct particles — in this case, electrons — the particles are so...

Printing a new chapter in solar energy

Jul 06, 2022 (Nanowerk News) A simple and versatile nanoparticle ink could help next-generation perovskite solar cells to be printed at scale and become the dominant force in commercial photovoltaics. Made from tin oxide, the ink is created with just one key step at relatively low temperature using microwave technology,...
