Commercial materials of α-β phase brass include high-strength brass.
The results of EDS and XRD analyses of extruded alloys were almost same as that of cast materials.
In the second place, as shown in Fig.1, the microstructures of extruded materials were finer than cast materials.

Introduction
Nano sized metal particles have great interest as they are effectively a bridge between bulk materials and atomic or molecular structures.
Recently various inorganic anti bacterial materials containing silver have been developed and is available commercially use [1].
Materials and methods Silver films were deposited on glass and stainless steel (316L) substrates which is cleaned by usual procedure with metal silver wire (99.9%) by thermal evaporation method.

Classfly ash (FA) with the specific surface area of 620 m2/kg and ground blast furnace slag (GGBS) with the specific surface area of 450 m2/kg were used as supplementary cementitious materials.
This is probably attributed to the pozzolanic activity and filler effect of mineral admixtures, which promotes the hydration of cementitious materials and refines the pore system of concrete.
Meanwhile, replacement of Portland cement with mineral admixtures reduces C3A content in cementitious materials, which also reduces the content of aluminate hydrates to react with chloride ion, seen from the decreased amount of calcium chloroaluminate and ettringite in XRD analysis.

Introduction
Multi-material structures are of great interest due to their combination of the superior properties of both materials compared to the conventional single metal.
The challenge in integrating incompatible materials such as copper and steel is in the interface bonding since it is analogous to producing steel on a steel substrate when fabricating the upper layers.
Materials and Methods The SLM equipment and process parameters producing Cu-Cr substrate (100mm×60mm×6mm) were detailly described in our previous publication [4].

Fig. 1 China’s Coal Consumption & CO2 Emissions from 2005 to 2012
Direct coal combustion is the most important source of carbon emissions
The thermal power (including power plant-supplied heat), metallurgy (including coking plant), building materials, and the chemical industries are the main sources of coal consumption in China (see Fig. 2).
