The alignment behavior of the liquid crystal layer of a liquid crystal display (LCD) determines most of its optical properties. The alignment direction and pretilt angles are determined by the alignment layers in contact with the liquid crystal layer itself and cannot be varied. Some traditional way.....

A new type of liquid crystal display (LCD) is invented. Common LCDs are transmissive with a front and a back polarizer. For viewing in reflection, a diffuser and a mirror are added to the back of the LCD. The new LCD is a true reflective LCD where there is no rear polarizer. The LCD is simple in.....

At present, graphite is a commonly used negative electrode material in the commercial graphite based second lithium ion batteries. The theoretical graphite carbon can have a specific capacity of 372 mAh/g, corresponding to an intercalation ratio of lithium to carbon 1:6 (LiC6.). However, such capaci.....

Most of the cytotoxic drugs used in cancer chemotherapy have narrow chemotherapeutic utility and effectiveness and serious side effects at high dosages. As a result, drug delivery systems have been developed to modify the biodistribution of cytotoxic drugs, improving their selectivity for tumors or .....
