    Synthesis, growth and characterization of 1-(5-chlorothiophen-2-yl)-3-(2,4, 5-trimethoxyphenyl) prop-2-en-1-one single crystal: A potential NLO material
    (2011) Prabhu, A.N.; Upadhyaya, V.; Arasalike, A.; Maddasani, M.; Manjunatha, K.B.; Umesh, G.
    A potentially useful nonlinear optical (NLO) organic material, 1-(5-chlorothiophen-2-yl)-3-(24,5-trimethoxyphenyl)prop-2-en-1-one(CTTMP), has been synthesized and grown as a high-quality single crystal by the slow evaporation technique. The grown crystals were characterized by UV-visible spectroscopy. The material has thermal stability up to its melting point. Single beam Z-scan technique was employed to study the third order NLO properties of the material. © 2011 American Institute of Physics.

    A detailed study on hybrid plant fibers for packaging applications
    (2012) Saravana Bavan, D.; Mohan Kumar, G.C.
    Natural fibers are the most economic and usable fibers in upcoming generation of composite industries. They are valid in several applications of automotive sectors, structural field, and packaging industries. The present work is focussed on processing a hybrid plant fiber of vetiver and maize that can be used for packaging industries. The hybrid fiber is processed through Vacuum Assisted Resin Transfer Molding (VARTM) method. The obtained fiber is a biocomposite material of plant fiber and bio resin of epoxodized soya bean oil. The material is tested for mechanical, thermal and morphology properties and it can be summarized that these novel hybrid fibers are good looking and have appreciable properties that can be used for packaging applications. These materials are green and less harm to environment compared to synthetic fibers.

    Mechanical characterization of adhesive layer using Double strap joint specimens
    (Elsevier Ltd, 2022) Sahana, T.S.; Kaliveeran, V.; Kundapura, S.
    In practical applications, most of our mechanical and civil structures are subjected to either oscillatory or static load. To design those structures, stress analysis is needed to withstand the design loads. In experimental stress analysis, strain gauges are mounted on those structures to determine stress at a point. Usually, strain gauges are mounted on the substrate using proper adhesives. The quality of strain data is a function of proper mounting. The thickness of adhesives used for mounting techniques should be optimum and very thin to ensure quality results. The underlying adhesive layer acts as an interface between the substrate and the strain gauge. This adhesive layer receives the maximum shear stress when the member is loaded in tension. Therefore, in this research work, the main focus is on characterizing the Araldite adhesive material. A tension test was conducted on the prepared bulk specimen to characterize the adhesive. The Double Strap Joint (DSJ) tests were conducted to investigate the interfacial shear strength and failure modes according to ASTM D 3528 standards. Two sets of specimens, such as plain and knurled straps, were used in this research work. The failure mode in the plain strap joint shows cohesive failure, and the knurled strap joint shows adhesive failure. © 2022
