Abstract Electrochemical nitrogen reduction reaction (eNRR) is recognized as a promising approach for ammonia synthesis, which is, however, impeded by the inert and unavoidable competing hydrogen evolution (HER). Here, Mo‐PTA@CNT electrocatalyst in Mo species are anchored on fourfold hollow sites of phosphotungstic acid (PTA) closely embedded multi‐walled carbon nanotubes (CNT) immobilization designed synthesized. Interestingly, catalyst presents high yield rate 51 ± 1 µg h −1 mg cat. an...

Abstract The unique morphology of 2D van der Waals materials enables them to withstand large deformations and significant nonuniform strain, potentially inducing a strong flexoelectric effect. Despite the size‐dependent effect showing potential for modulating optoelectronic performance materials, it is far from being fully exploited owing various challenges.

In flexoelectricity, a strain gradient can induce polarization and mechanical stress. this paper, in order to identify the contributions of each component, flexoelectric theory is reformulated by splitting tensor into mutually independent parts. Two sets orthogonal higher-order deformation metrics are inherited perfected reformulate internal energy density for isotropic materials. The deviatoric stretch symmetric part rotation proved disappear coupling and, moreover, constants associated...

The interplay between light and magnetism sparks groundbreaking concepts for the next-generation versatile spintronic nanoelectronic devices. However, direct measurements of light-magnetism coupling remain challenging due to intrinsic difficulties in characterizing these properties simultaneously.

Two-dimensional conductive metal-organic frameworks (2D c-MOFs) are a family of highly tunable and electrically conducting materials that can be utilized in optoelectronics. A major issue 2D c-MOFs for photodetection is their poor charge separation recombination dynamics upon illumination.
