LiMn0.6Fe0.4PO4/C cathode material is synthesized via a modified-solid state reaction method. The calcination temperature is adjusted in the range of 500-700 degrees C for 10 h. The crystal structure, morphology, and carbon coating layer of the synthesized LiMn0.6Fe0.4PO4/C are analyzed using...
Ultra-fine WS_2 powders were synthesized via an improved solid reaction method from mixed(tungsten) and sulfur powders with different excessive sulfur coefficients(ESC),followed by the reactions in N_2 or Ar atmosphere at different temperatures.Phase composition,morphology and particle size of the re...
The immobilization of one reactant on a solid support makes interfacing of reagents a critical challenge in solid-phase synthesis. Here, authors combine dielectrophoresis and droplet microfluidics to encapsulate and eject individual beads out of reagent droplets for improved reaction fidelity. ...
in the reacting system because of crystallographic matching. Solid-phase epitaxy, or the introduction of solid seed particles to a system undergoing a solid-state reaction as a means of controlling ceramic reactions, has been demonstrated to be an effective means to control solid-state kinetics, mi...
The solid state reaction between copper and silicon has been studied in the temperature range 350 to 650°C. The rate-limiting step is the diffusion of copper through the main product Cu 3Si. When pure copper is used, a bulk diffusion mechanism is operative above 470°C, and the activation...
