Triboelectric materials present great potential for harvesting huge amounts of dispersed energy, and converting them directly into useful electricity, a process that generates power more sustainably. Triboelectric nanogenerators (TENGs) have emerged as a technology to power electronics and sensors, and it is expected to solve the problem of energy harvesting and self‐powered sensing from extreme environments...
The limited ionic conductivity and unstable interface due to poor solid–solid interface pose significant challenges to the stable cycling of solid‐state batteries (SSBs). Herein, an interfacial plasticization strategy is proposed by introducing a succinonitrile (SN)‐based plastic curing agent into the polyacrylonitrile (PAN)‐based composite polymer electrolytes (CPE) interface. The SN at the interface...
2D non‐layered materials (2DNLMs) featuring massive undercoordinated surface atoms and obvious lattice distortion have shown great promise in catalytic/electrocatalytic applications, but their controllable synthesis remains challenging. Here, a new type of ultrathin carbon‐wrapped titanium nitride nanomesh (TiN NM@C) is prepared using a rationally designed nano‐confinement topochemical conversion...
To realize practical lithium–sulfur batteries (LSBs) with long cycling life, designing cathode hosts with a high specific surface area (SSA) is recognized as an efficient way to trap the soluble polysulfides. However, it is also blamed for diminishing the volumetric energy density and being susceptible to side reactions. Herein, polyethylenimine intercalated graphite oxide (PEI‐GO) with a low SSA...
Downstream studies of circulating tumor cells (CTCs), which may provide indicative evaluation information for therapeutic efficacy, cancer metastases, and cancer prognosis, are seriously hindered by the poor purity of enriched CTCs as large amounts of interfering leukocytes still nonspecifically bind to the isolation platform. In this work, biomimetic immunomagnetic nanoparticles (BIMNs) with the...
Pt‐Gd alloy polycrystalline thin film is deposited on 3D nickel foam by pulsed laser deposition method serving as a whole binder/carbon‐free air electrode, showing great catalytic activity enhancement as an efficient bifunctional catalyst for the oxygen reduction and evolution reactions in lithium oxygen batteries. The porous structure can facilitate rapid O2 and electrolyte diffusion, as well as...
