Core–Shell Structured Silicon Nanoparticles@TiO2–x/Carbon Mesoporous Microfiber Composite as a Safe and High-Performance Lithium-Ion Battery Anode

Abstract: A core–shell structured Si nanoparticles@TiO2–x/C mesoporous microfiber composite has been synthesized by an electrospinning method. The core–shell composite exhibits high reversible capacity, excellent rate capability, and improved cycle performance as an anode material for Li-ion batteries. Furthermore, it shows remarkable suppression of exothermic behavior, which can prevent possible thermal runaway and safety problems of the cells. The improved electrochemical and thermal properties are ascribed to the mechanically, electrically, and thermally robust shell structure of the TiO2–x/C nanocomposite encapsulating the Si nanoparticles, which is suggested as a promising material architecture for a safe and reliable Si-based Li-ion battery of high energy density.

One-Step Exfoliation Synthesis of Easily Soluble Graphite and Transparent Conducting Graphene Sheets

Abstract: Easily soluble expanded graphite is synthesized in a one-step exfoliation process that can be used for the lowcost mass production of graphene for various applications because of the simplicity and speed of the process. The graphene obtained is sufficiently expanded to be dispersed in aqueous solutions with an ordinary surfactant and in organic solvents.

Liquid crystal display device and method of driving the same

Abstract: A liquid crystal display device includes a timing controller, a data driver, a gate driver and a liquid crystal panel. The timing controller receives an image data signal to output a first control signal, a second control signal and a data signal corresponding to the image data signal. The data driver outputs first and second gray scale signals having different gray scale levels in response to the first control signal and the data signal. The gate driver outputs a gate signal in response to the second control signal. The liquid crystal panel includes a plurality of pixels aligned in a matrix and displays an image in response to the first gray scale signal, the second gray scale signal and the gate signal. Each of the pixels of the liquid crystal panel includes a first sub-pixel, to which the first and second gray scale signals are alternately applied in one frame unit, and a second sub-pixel, to which the first gray scale signal is applied.
