Pulsed laser deposition is a technique that is capable of producing high quality multicomponent films under a broad range of ambient conditions. This technique has been widely used to grow thin films of numerous compounds. In particular, it enables the growth of films in reactive environments such as oxygen and nitrogen. Pulsed laser deposition of novel oxides such as cerium oxide (CeO 2 ), Gd doped cerium oxide (GDC) and La-Sr-Ga-Mg-O (LSGM) on (111) Si, (100) MgO, (100) YSZ and (012) sapphire substrates is demonstrated. A systematic study on the influence of the substrate temperature and substrate orientation on the growth characteristics of these oxides is reported.
Most studies on the application of natural fibers as reinforcement in polymer composites are growing as a result of the changes in characteristics that fibers can provide for the product. This can be achieved by manufacturing of composites using Hand Layup process. The 2% NaOH fiber treatment was performed to improve fiber-matrix interfaces making spathefibre-reinforced composites better mechanical characteristics. Filler loadings as 5% by volume of coir fiber are selected as reinforcement in composites. The varying lengths of fiber chosen as 5mm, 10mm & 15mm and resin-hardner ratio are maintained as 10:0.8. A total 3 numbers of plates with volume as 300 х 300 х 4 mm3 were produced and specimens as per the various ASTM standard were tested to determine the ultimate various Mechanical properties for different configuration. The strength of epoxy resin / coir fiber composites was noticed at a maximum 15 mm (15.27 N / mm2 ) fiber length. The maximum impact strength of the charpy was also 15 mm fiber length (9.87 kJ / m2 ).The Experimental results were validated using a numerical method technique in FEA software. The obtained results by experimentation and Finite Element Analysis are very much closer to each other. The results show good mechanical properties and hint us as a replacement for conventional materials in industrial applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
