Transition Metal Chalcogenides for the Electrocatalysis of Water

, 2020
Sustainable energy technology has received enormous attention in recent years. Specifically, electrochemical water splitting is considered to be the cleanest technique for the production of promising fuels, for example, hydrogen and oxygen, where transition metal (di)chalcogenides (TMCs) as electrocatalysts for hydrogen evolution reaction (HER) and ...

Parity‐Dependent THz Harmonic Generation in Electrically Pumped Micro‐Lasers Exploiting Topological Insulator–Metamaterial Gratings

Advanced Materials, EarlyView.
Topological insulator–metamaterials integrated with electrically driven terahertz quantum cascade lasers enable parity‐dependent harmonic generation. Bulk‐dominated Bi2Se3 favors third‐harmonic emission at 9.96 THz, whereas topological‐surface‐state‐dominated Bi2Se3, Bi2Te3, and (Bi,Sb)2Te3 generate strong second harmonics near 6.5 THz.

Atomically Dispersed Fe-Modified SnS for Sn-Centered Peroxymonosulfate Activation Toward Acetaminophen Degradation. [PDF]

Adv Sci (Weinh)
Atomically dispersed Fe regulates the local electronic environment and surface properties of SnS, while PMS preferentially coordinates to Sn through Sn–O interaction. Fe incorporation further enhances the Sn–OPMS interfacial interaction, facilitating Sn‐centered PMS activation and the generation of SO4•−/•OH for APAP degradation, thereby clarifying the
