This paper proposes a novel three-phase nine-switch ac/ac converter topology. This converter
features sinusoidal inputs and outputs, unity input power factor, and more importantly, low …

A novel rectifier topology consisting of two three-phase diode bridges and three thyristors is
proposed in the paper for variable-speed high-power permanent-magnet synchronous …

… Jiacheng Wang Jiacheng Wang received his PhD in materials physics and chemistry from
Shanghai Institute of Ceramics, Chinese Academy of Sciences in 2007 under the supervision …

Nontrivial topological surface states (TSSs), which possess extraordinary carrier mobility and
are protected by the bulk symmetry, have emerged as an innovative platform to search for …

The replacement of platinum with non‐precious‐metal electrocatalysts with high efficiency
and superior stability for the hydrogen‐evolution reaction (HER) remains a great challenge. …

The sluggish kinetics of Oxygen Reduction Reaction (ORR) at the cathode in proton
exchange membrane fuel cells or metal-air batteries requires highly effective and stable …

Methanol manufacturing by CO 2 electrolysis is a potential near-zero-emission route to
carbon neutrality, but most of the previous studies in aqueous electrolytes have achieved poor …

Urea electrolysis can convert urea from urea‐rich wastewater to hydrogen for environmental
protection and sustainable energy production. However, the sluggish kinetics of urea …

The hydrogen spillover effect has garnered considerable attention as a promising avenue to
enhance the activity of the hydrogen evolution reaction (HER) in metal‐support compound …

Zinc (Zn) metal is considered the promising anode for “post‐lithium” energy storage due to
its high volumetric capacity, low redox potential, abundant reserve, and low cost. However, …
