Guangdong Academy of Social Sciences suggested that Guangdong now faced with a series of new challenges: First, resource-dependent development of epitaxial growth model, has been faced with resource and environmental challenges of tight constraints, likely to lead to unsustainable development crisis.
This mode of development, on the one hand achieved three decades of brilliant, on the other hand, Guangdong is entered into the dilemma of not sustainable: within the limits of ensuring sustainable development, land resources had become exhausted, extension development is approaching the limit, and the growth model of extension expansion can’t be sustainable; With the increase of economic development level, and the rapid increase in labor costs, labor-intensive industries will be difficult; the extensive processing and manufacturing system, which rely on a lot of consumption of material resources as the prerequisite, is facing the severe impact of a global shortage of resources and price increases; the fierce international competition is leading to the beginning of the policy of government intervention in the Western countries and protectionism in international trade, and export-oriented labor or resource-intensive processing and manufacturing industry caused great international pressure
For example, in personal computer, there is about 7% of copper, 14% aluminum, 20% iron , 2% zinc, plastic 23% and other environmentally friendly and high-value material about 66%; it also contains 6% lead, 0.002% mercury and 0.009% of cadmium and other substances harmful to the environment up to around 6%, glass and other material about 28%.

Cobalt
silicides attract much attention because of their possible application as interconnect material.
These studies suggest that linear interface shift may occur due to large difference in the diffusion coefficients of the materials in contact (diffusion asymmetry), even if there is no any extra potential barrier present, accounting for an interface reaction control.
Multilayered samples were used to increase the amount of material to be detected.

Sometimes, increasing the substitution concentration for same doping materials lead to the reduction of the TC values and induces the subsequent metal-insulator cross over.
A porous microstructure is a material which have specific properties that can improve the JC values [6].

That's why PCD is in heavy use as a cutting tool for
hard to machine materials and as wear parts.
Grain sizes of the diamond material used are d=2, 5, 10 and 25µm.
It was also thought that C-EDG could achieve material removal of diamond itself as well as cobalt as shown in Fig.2(b).

However, the adulterated materials used to dilute free CaO are subject to geographical constraints.
The raw materials collected are, on the one hand as the test samples, on the other hand, in order to understand CaCO3 content in purple sandy shales in regional area.
The sintering process is simulated as the field to crash (<2 mm) and mingle the raw materials by the rock/coal mass ration of 20:1 for making brick samples [5].
By simulating current sintering technique [5], the raw materials are ground (<2 mm) and mixed in term of rock/coal mass ration of 20:1.

Prevention of water-wall tubes corrosion can be achieved by changing in operation procedures
and replacement of tube materials.
The replacement of more corrosion resistant material on Cr rich steel or Cr-Ni steel is possible but other problems appear connected with high costs of installation and low heat transfer coefficients of such materials.

Introduction
Inventories of engineering materials from metals are decreasing, so it takes a lot of innovation to make new materials used in the engineering fields.
The process is doing by combining two or more materials in particular conditions to produce engineering materials with specific mechanical properties.
One of the example of the material used by many researchers is the polypropylene matrix which is combined with reinforcing materials from various materials.
These results are preliminary data that can be used to develop further composite materials both in terms of materials and processes, so that they can obtain better and stronger composite materials.
