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].

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.

The software materials of reuse not only include the module's code, also include other software material.
When to use the careful mode of building strategy, in order to reflect "flexibility", according to the available materials and experience, for every stage of the development process, people should imagine the changes that may occur.

The Ecological Crisis in Development of Chongqing Electronic Information Industry Meihua Zhang1, a, Xinyi Xiang1, b and Qiang Wu2, c 1School of Geographical Sciences, Southwest University, Chongqing, China 2 Chongqing Communist Youth League School, Chongqing, China aXyz007aoe@163.com, bruoqing@swu.edu.cn, c568838777@qq.com Keywords: Chongqing, the electronic information industry, ecological crisis, the development of the trap, the scientific development.
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%.

The filtration basin can make the water clarify mainly depending on the filtration materials, which we commonly used, including quartz sand and anthracite grain.
Then the water arrives in the reaction basin to grow gradually into the flocculent deposit material (flocculating constituent or vitriol flower).

Large amounts of solids from inadequately treated sewage containing organic material accumulate on the banks of the receiving waters, settle at the bottom to form sludge deposits, or float on the surface to form scum.
Materials and Methods Sewage effluent samples were aseptically collected weekly from three near shore house-boat and three offshore platform WWTP discharge point for physico-chemical and coliform characterization using 1litre plastic and 200ml sterile glass bottles respectively.

ALE is unique because it is making use of self-limiting reactions that only modify the thin top surface layer of the material.
DeSalvo et al. reported one of the first wet ALE approach for GaAs and other III–V semiconductor materials using oxidation in solution followed by selective dissolution of the oxidized layer [1].

The cushion materials are continuously added to the inter-pile soil,causing it bears more loads.
That because when there are same material and internal friction angle, the thicker the cushion is, piles can more easily prick into it, and the bearing capacity of the inter-pile soil is fully developed.
