Reactive hydride system of 2LiH + MgB2/2LiBH4 MgH2 is great potential as hydrogen storage material due to its high theoretical capacity. However, it suffers from sluggish dehydrogenation/hydrogenation kinetics and poor cyclic stability. In the present study, with incorporation a 2D MXene phase Ti3C2 MgB2 mixture by ball milling followed an initial hydrogenation, hydrogenated 2LiBH4 shows superior 9.0 wt % H2 released at 400 °C within 20 min. The dehydrogenation product can be highly 350...
To satisfy the needs of precision machining, ultrafine tungsten carbide (WC)-based cemented with fine grain size and excellent mechanical properties was prepared. Ultrafine prepared by spark plasma sintering (SPS) using WC, Co as raw materials metal elements V, Cr additives, effects on microstructure were investigated.

Chromium carbide nanopowders were synthesized by mechanical alloying-assisted microwave heating. The effect of gamma irradiation on phase composition and microstructure chromium the heating method was analyzed. samples characterized X-ray diffractometry (XRD), photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission (TEM), high-resolution (HRTEM) techniques. results showed that well-dispersed can be maintaining temperature at 1000 °C for 1 h. Gamma ray had an...
To achieve large-scale hydrogen storage for growing high energy density and long-life demands in end application, the 2LiBH4-MgH2 (LMBH) reactive hydride system attracts huge interest owing to its capacity thermodynamically favorable reversibility. The sluggish dehydrogenation kinetics unsatisfactory cycle life, however, remain two challenges. Herein, a bimetallic titanium-niobium oxide with two-dimensional nanoflake structure (2D TiNb2O7) is selected elaborately as an active precursor that...
Effective utilization of solar energy for the production thermal is regarded as one most sustainable ways to conquer growing global crisis. Photothermal conversion at water–air interface considered be a promising route steam generation, distillation, and desalination. However, interfacial photothermal evaporators often require optical concentrators complicated systems with multiple components, leading poor efficiency high cost. Herein, an extremely simple low‐cost heating film highly...
