Monatomic steps with a height of 0.25 nm on ultraflat Au(111) surfaces during electrochemical dissolution can be seen for the first time by a laser confocal microscope combined with a differential ...

In this article, a nine-level multilevel topology is proposed by stacking of low voltage basic inverter cells and then cascading with H-bridges. The dc-link is split into four equal halves by ...

Shardeum’s Approach: Autoscaling PayFi. Shardeum is being built to bring the vision of a decentralized payment system at scale to life. It aims to be the world’s first auto-scaling Layer-1 ...

Vertical and lateral heterogeneous structures of two-dimensional (2D) materials have paved the way for pioneering studies on the physics and applications of 2D materials. A hybridized hexagonal boron ...
