Over the past several years, it has become increasingly evident that materials for proposed advanced energy systems will be required to operate at high temperatures and in aggressive environments. These constraints make structural ceramics attractive materials for these systems. However it is well known that the condition of the specimen surface of ceramic materials is often critical in controlling properties such as fracture toughness, oxidation resistance, and wear resistance. Ion implantation techniques offer the potential of overcoming some of the surface related limitations.While the effects of implantation on surface sensitive properties may be measured indpendently, it is important to understand the microstructural evolution leading to these changes. Analytical electron microscopy provides a useful tool for characterizing the microstructures produced in terms of solute concentration profiles, second phase formation, lattice damage, crystallinity of the implanted layer, and annealing behavior. Such analyses allow correlations to be made with theoretical models, property measurements, and results of complimentary techniques.

Experimental and theoretical study Porphyrin-grafted ZnO nanowire arrays were investigated for organic/inorganic hybrid solar cell applications. Two types of porphyrin – Tetra (4-carboxyphenyle) TCPP and meso-Tetraphenylporphine (Zinc-TPP)were used to modify the nanowire surfaces. The vertically aligned nanowires with porphyrin modifications were embedded in graphene-enriched poly (3-hexylthiophene) [G-P3HT] for p-n junction nanowire solar cells. Surface grafting of ZnO nanowires was found to improve the solar cell efficiency. There are different effect for the two types of porphyrin as results of Zn existing. Annealing effects on the solar cell performance were investigated by heating the devices up to 225 °C in air. It was found that the cell performance was significantly degraded after annealing. The degradation was attributed to the polymer structural change at high temperature as evidenced by electrochemical impedance spectroscopy measurements.

Breast cancer left overs one of the greatest common metastasis disease in females. Advanced diagnostic devices and better understanding of tumour biology can extend the better therapeutic outcomes. Nanotechnology is a tool that helps in cancer diagnosis and treatment therapy. Many nanocarriers such as solid lipid nanoparticles, magnetic nanoparticles, nanocrystals, nanogels, nano-lipid nanocarriers, biodegradable nanoparticles, liposomes, and dendrimers are introduced to improve the therapeutic efficacy of antineoplastic agents. Surface modified target drug delivery system has the potential to increase the therapeutic effects and also reduce the cytotoxicity of breast cancer. Different approaches have been explored for treatment of breast cancer. This review describes the recent advances in the development of nanocarriers used for the targeted treatment of breast cancer. It also focuses on etiology, risk factor and conventional therapy of breast cancer. KEYWORDS: Breast Cancer; Nano-carriers; Tumor Targeting; Ligands; Receptor.
