Magneto‐Ionic Devices With Polymer‐Based Electrolytes

Advanced Functional Materials, EarlyView.
Polymer electrolytes are introduced for magneto‐ionic devices based on hydroxide and hydrogen ions. The magneto‐ionic effect results in a pronounced voltage‐controlled variation of coercivity in both devices. The switching speed is in the range of 100 ms.

Heteroengineering‐Induced Electronic Reconstruction for Ammonium‐Ion Energy Storage

Advanced Functional Materials, EarlyView.
An integrated electronic reconstruction behavior is induced by local heteroengineering on VO2(B) electrode material surface of NH4+ supercapacitor, rationally modulating the electronic structure, enabling enhanced intrinsic conductivity and extra driving force for NH4+ intercalation reaction.

Adsorptive cathodic stripping voltammetry of amethopterin at a static mercury drop electrode and its application to serum drug determination.

, 1988
The adsorptive behavior of amethopterin (methotrexate) at a static Hg drop electrode in neutral and basic solns. (which is very different from the behavior in acidic media) is described. The anal. potential of cathodic stripping voltammetry coupled with

Phase Boundary Engineering of Co2P‐CoP Branched Nanoparticles Enhances Cobalt Oxidation for Oxygen Evolution Electrocatalysis

Advanced Materials, EarlyView.
Phase boundaries between Co2P and CoP are constructed through a controlled transformation of Co to Co2P‐CoP branched nanoparticles. The polycrystalline mixed‐phase Co2P‐CoP branches are enriched with phase boundaries that stabilize Co active sites for OER. This work highlights phase boundary engineering as a powerful approach to tailor active sites and

Phase‐Engineered MoS2 Quantum Monolayer Catalysts

Advanced Materials, EarlyView.
A new type of catalyst model—phase‐engineered MoS2 quantum‐monolayer catalyst (∼0.8 nm thick, < 6 nm in the lateral size; switchable freely among metallic 1T, semiconducting 2H, and a hybrid phase of metallic‐semiconducting 1T‐2H)—is reported. It can efficiently and stably drive photochemical H2, syngas and ammonia synthesis as a catalyst or co ...
