Abstract
The advances in liquid crystal lubrication and liquid crystals as lubrication additives were reviewed in this paper. Recent theoretical studies and application results were discussed for two different kinds of liquid crystals—lyotropic liquid crystals and thermotropic liquid crystals. Their antifriction and antiwear mechanisms under different experimental conditions were illustrated. The lubrication functions of adding liquid crystals as lubrication additives in to some regular greases and synthetic oils were commented.

Abstract
This paper presented the new results on catalysis reaction mechanism of methanemonooxy genase in recent years. Activation of the stable C—H bond of methane is thought to occur via either a radical rebound mechanism or a concerted in sertion of an oxygen atom. The studies using radical clock and quantum chemical calculations showed that there was not a consistent mechanism to clarify the reaction courses of methane monooxygenase. The type of mechanism may depend on source of methane monooxygenase or other factors. The spectro scopic analysis on the intermediates of methane monooxygenase accelerated the mechanism development of studies on methane monooxygenase.

Abstract
Combinatorial Chemistry is the hot point in the fields of materials science and chemistry, which is first used in synthesizing new medicines. Soon this method is used in other fields, including synthesizing functional materials due to the short synthesizing cycle, big quantity of products, saving expenses and so on. There are many kinds of methods in combinatorial chemistry, which can be categorized into combinatorial chemistry in liquid and combinatorial chemistry in solid state by the reaction states, and the combinatorial chemistry in solid state can also be recategorized into binary mask method, quaternary mask method and movable shutter mask, etc. This review reports the combinatorial chemistry used in synthesizing functional materials.
