The basics and uses of the micellar system extraction technique (MSE) for extracting and preconcentrating nanoparticles and bioactive compounds (medicines and vitamins) are covered in this review. Hence, the influential factors of the MSE and applications are offered. The MSE, like any separation process, extracts the analytes in a small phase from the solution to improve analysis quality and remove sample background interference. The MSE has several advantages over other preconcentration and separation methods, such as speed, cheapness, security, selectivity, and safety. The use of toxic organic solvents is reduced or ignored, and the process is economical and environmentally friendly. In the latest works of literature, three different procedures use to extract nanomaterials. So bioactive molecules were separated by two methods with MSE, and this review also provided newly-developed MSE.

Anthracene is the backbone of three suggested organic compounds in present work. Our calculations depending on DFT and TD-DFT take on B3LYP hybrid function using the basis sets 6-31g to carry out some properties at the ground state electronic and photovoltaic properties for the studied compounds. The relax structures show all the compounds have quasi planar conformation. The results showed that Homo and Lumo are little different, suggesting that be different structures play substantial characters to increase an electron acceptance. The result of( Lumo-Homo) gap and the voltage of open circuit are the factors operating to refining the quality for devices of solar cells. Furthermore, due to the high probability of the process for an electron injection of the organic structure in the TiO2 conduction band, where the energy of maximum absorption and the wavelength are occur in the range spectrum of the solar.

This article describes a new generation of low temperature Argon (Ar) sputtering Preclean. A ceramic electrostatic chuck (E-Chuck) was integrated to provide active wafer cooling. Wafer temperature, which is critical to gate oxide degradation in a plasma ion bombardment and charging environment, was reduced from 250°C to 75°C. This significantly improved the antenna yield due to reduced gate oxide damage and achieved the same etch performance.

In this work, a solar concentrator was constructed using liquid crystalline material of the isotropic type to increase the efficiency of the solar cell. Two different concentrations of this liquid crystal were prepared and mixed with epoxy resin to manufacture the plates with an equal area of solar cell space. having Considered this kind of mixture, it was found that a high concentration of this material has contributed to increase the efficiency of the solar cell from 8.51 to 10.85, were also calculated the absorption, fluorescence spectra, short circuit current (Isc), open circuit voltage (Voc) and fill factor(FF). The quantum efficiency of fluorescence in this concentration was (93%, 90%).
