Effect of In-Situ TiB<sub>2</sub>Particle Addition on the Mechanical Properties of AA 2219 Al Alloy Composite

Journal of Minerals and Materials Characterization and Engineering 2011年第6期10卷 527-534页

作者： N.R. Rajasekaran v. sampath Department of Metallurgical and Materials Engineering Indian Institute of Technology Madras Chennai – 600 036

Aluminium alloy AA2219 was reinforced with TiB2 particles introduced in-situ by the saltmetal reaction technique. The microstructural examinations of the composites clearly rev.al the formation of TiB2 particles with a hexagonal morphology. The addition of TiB2 particles results in increased mechanical properties, such as 0.2%YS, UTS and hardness. The improv.ment in mechanical properties is correlated to the microstructure.

Low-Cost Dye-Sensitized Solar Cells Based on Interconnected FTO-Activ.ted Carbon Nanoparticulate Counter Electrode Showing High Efficiency

引用

材料科学与工程（中英文A版） 2015年第9期5卷 361-368页

作者： Chandana sampath Kumara Ranasinghe Eranji Nirmada Jayaweera Gamaralalage Rajanya Ashoka Kumara Rajapakse Mudiyanselage Gamini Rajapakse Herath Mudiyanselage Nav.rathna Bandara Masamichi Yoshimura Department of Chemistry Faculty of Science University of Peradeniya Peradeniya 20400 Sri Lanka Postgraduate Institute of Science University of Peradeniya Peradeniya 20400 Sri Lanka Graduate School of Engineering Toyota Technological Institute 2-12-1 Hisakata Tempaku-ku Nagoya 468-8511 Japan

The dev.lopment of low-cost DSCs (Dye-sensitized solar cells) based on activ.ted carbon counter electrodes is described. Although, the use of activ.ted carbon in CEs (Counter electrodes) has been documented, the efficiencies obtained in such solar cells hav. been low, particularly, due to low electrical conductiv.ty of such counter electrodes. Our design of the counter electrode eliminates this problem by using an in-situ formed FTO (Fluorine-doped tin oxide)-activ.ted carbon composite on FTO surface as the CE. The FTO particles are prepared by atomized spray pyrolysis method from a spray solution containing dispersed activ.ted carbon particles. The CE thus prepared has a reasonable electronic conductiv.ty and the composition of the spray solution was optimized to giv. the highest conv.rsion efficiency and the thickness of the CE was optimized by controlling the spray duration and deposition temperature. The best DSC based on AC-FTO CE has a JSC of 18.98 mA·cm-2, a v.C of 0.709 v. and a FF (Fill factor) of 0.563 giv.ng a conv.rsion efficiency of 7.6%. The data for Pt-FTO CE based DSC are a JSC of 18.78 mA·cm-2, a v.C of 0.732 v. and a FF of 0.688 with a conv.rsion efficiency of 9.5%.
