Designing definite transition metal heterointerfaces is considered an effective strategy for the construction of efficient and robust oxygen evolution reaction (OER) electrocatalysts, but rather challenging. Herein, amorphous NiFe hydr(oxy)oxide nanosheet arrays (A‐NiFe HNSAs) are grown in situ on the surface of a self‐supporting Ni metal–organic frameworks (SNMs) electrode via a combination strategy...
The structural and morphological changes of the Lithium superionic conductor Li10GeP2S12, prepared via a widely used ball milling‐heating method over a comprehensive heat treatment range (50 – 700 °C), are investigated. Based on the phase composition, the formation process can be distinctly separated into four zones: Educt, Intermediary, Formation, and Decomposition zone. It is found that instead...
The majority of commercial polyolefins are produced by coordination polymerization using early or late transition metal catalysts. Molecular catalysts containing these transition metals (Ti, Zr, Cr, Ni, and Fe, etc.) are loaded on supports for controlled polymerization behavior and polymer morphology in slurry or gas phase processes. Within the last few years, metal–organic frameworks (MOFs), a class...
Two‐dimensional nanofluidic membranes offer great opportunities for developing efficient and robust devices for ionic/water‐nexus energy harvesting. However, low counterion concentration and long pathway through limited ionic flux restrict their output performance. Herein, it is demonstrated that rapid diffusion kinetics can be realized in two‐dimensional nanofluidic membranes by introducing in‐plane...
Though plasmonic effect is making some headway in the energy harvesting realm, its fundamental charge transfer mechanism to a large extent is attributed to the hot‐carrier generation at the contact interface. Herein this work attempts to elucidate the physical origin of light induced plasmo‐pyroelectric enhancement based on charge density manipulation on surface state in the vicinity of the metal–ferroelectric...
Surface plasmon‐based photonics offers exciting opportunities to enable fine control of the site, span, and extent of mechanical harvesting. However, the interaction between plasmonic photothermic and piezoresponse still remains underexplored. Here, spatially localized and controllable piezoresponse of a hybrid self‐polarized polymeric‐metallic system that correlates to plasmonic light‐to‐heat modulation...
The gate‐tunable phonon properties in bilayer MoS2 are shown to be dependent on excitation energy. Raman intensity, Raman shift, and linewidth are affected by resonant excitation, while a nonresonant laser does not influence the intensity significantly. The gate‐dependent Raman shift of A1g mode (either blue‐, red‐, or no‐shift) is a result of the combined effect of antibonding electron and resonant‐related...
Large‐area, 2D, anisotropic, direct growth of nanostructures is considered an effective and straightforward way to readily fulfill transparent, flexible technology requirements. In addition, formation of thin hybrid structures by combining with another 2D material brings about dimensional advantages, such as intimate heterostructure functionalities, large specific area, and optical transparency. Here,...
