The hybrid polymer-GaN nanocrystal heterojunction solar cell has been fabricated by blending of GaN and regioregular poly(3-hexylthiophene)(P3HT) through solution process and spin-coating on the glass substrate, in which the Gallium Nitride(GaN) nanocrystal was successfully synthesized by means of sol-gel process The cell shows the Voc and Isc of 0.71V and 3.5mA/cm2 Introduction There has been great interest in hybrid organic–inorganic solar cells due to their low materials cost and solution based processing techniques, creating the potential for large-scale,cost-effective solar cells.

Milling is the most practical machining operation for removing excess material.
Introduction With the development of fabrication of advanced materials, Carbon Fiber Reinforced Plastics (CFRP) has been used extensively in many industries due to its superior specific strength and high temperature resistance, high corrosion resistance and good thermal shock resistance [1-3].
However, due to the inhomogeneous and anisotropic material properties machining of CFRP comes along with certain difficulties like fiber pull-out, delamination and decomposition of matrix material which leads to a degradation of the surface quality and the material properties [4].

Before 1990s, the self-built house in the village used the masonry, wood as the building materials.
Meanwhile, both the roof and wallboard used the lightweight materials, so the earthquake resistant behaviour was very good.
The infilled frame structures was compose of all sorts of sintered concrete block, light wall materials etc.
Because the structural measure of wall materials and beam and column were imperfection, the earthquake damage was serious.

The friction heat caused at the grain-workpiece interface has attracted a lot of research in the field of grinding hard and brittle materials[2,3].
This might be attributed to the different material removal mechanisms for the two kinds of materials.
In grinding of brittle materials, material removal mechanisms are classified as brittle fracture (brittle mode grinding) and/or plastic flow (ductile mode grinding)[15].

Supercritical CO2 extraction is a new method of extracting materials and it is developed fast in chemical industry, but its application in coal was reported few.
But there are some basic questions remain to be answered which about coupling reaction mechanism between ScCO2 and minerals in coal, ScCO2 extraction of materials of coal petrography and their effects.
