Sectors such as housing, aerospace and automotive are rapidly growing in developing countries because of the increased demand due to the increasing population, which is one of the driving forces for the supply need and growth of light-weight high-strength materials like Al [2].
For the grain refiner master alloy to act as an effective dopant, the physical nature (shape, size morphology or number density) of the pre-existing phases in the master alloy play a key role in the microstructural development during casting [5].

On the other hand, nanoscale materials are expected to possess different electronic properties compared to their corresponding bulk crystals [1]; in particular, onedimensional nanostructures merit special attention, as they are expected to play a crucial function as building blocks of future molecular electronics applications.
During the last few years, experiments have exposed a variety of SiC-based nanoscale materials.
Due to a huge surface-to-volume ratio, the surface states have been recognized as playing a key role in determining the physical and chemical properties of semiconductor nanocrystals.
The numerical calculations are carried out at the fine precision level within the Materials Studio framework.
The results show that it could be possible to prepare SiC-NWs with a desired band gap by varying the thickness and morphology and performing band gap engineering.

Experimental study of breakthrough adsorption on activated carbon for CO2 capture Qigang Cen1,2,a, Mengxiang Fang1,b, Jiaping Xu1,c, and Zhongyang Luo1,d 1State Key Laboratory of Clean Energy Utilization, Zhejiang University, Hangzhou, China 2School of Energy and Power Engineering, Jiangsu University, Zhenjiang, China acenqigang@zju.edu.cn, bmxfang@zju.edu.cn, czjuxujp@zju.edu.cn, dzyluo@zju.edu.cn Keywords: CO2 capture; adsorption; activated carbon; breakthrough curve Abstract.
A wide variety of adsorbents for CO2 capture has been or is currently being investigated[5,6], including zeolites, carbon-based sorbents, supported amines, metal oxides and metal-organic frameworks (MOFs) materials.
Activated carbons can be produced from a variety of raw materials, which makes them much cheaper than other adsorbents.

Wind turbines are generally conceived as the key renewable energy sources, but more innovative solutions should augment the classical design and control of wind turbines in order to improve the energy conversion efficiency.
Identifying the stress distribution is very important for the design of the system including selection of blade material and blade cross section.
