Effect of Surface Free Energy on the Surface-Driven Capillary Flow in SU-8 based Glass Microfluidic Devices
Abstract: Surface-driven capillary flow of dyed water is recorded in the SU8 based glass microfluidic devices fabricated by the standard cleanroom processes. The effect of surface wettability on the surface-driven capillary flow is studied in the individual SU8 based microfluidic devices of glass bottom wall and polyimide bottom wall. The surface-driven capillary flow is faster on the glass bottom wall surface due to the higher polar component of solid surface free …

Application of Industrial Waste in Metal Matrix Composite
Abstract: AbstractKeeping the goals of protecting the environment and exploring low-cost options for the development of metal matrix composites (MMCs) using cheap reinforcing materials which obtained from recycling techniques of agro and industrial waste products become one of the new interest fields of the researchers. The industrial wastes reinforce materials in useful way not only save the manufacturing cost of products but also reduce the environmental pollution. This paper represents a …

Tensile and Impact Properties of Jute/Glass and Jute/Carbon Fiber Reinforced Polypropylene
Abstract: AbstractComposites have created a niche in the world market today as they provide a stiff, strong and lightweight material. Two types of composites polypropylene/jute/glass fiber and polypropylene/jute/carbon fibers were prepared by varying the percentages of jute, glass and carbon fibers, respectively. A proportion of 35:5, 30:10, 25:15 and 20:20 were maintained between jute and other reinforcing fiber (glass or carbon) in polypropylene matrix. Tensile and impact test specimens were prepared …

Characterization and Gamma Irradiated MA-EMA Copolymer by ESR and FTIR Techniques
Abstract: AbstractGamma irradiation effect of methacrylamide-ethyl methacrylate (MA-EMA) copolymer has been investigated by electron spin resonance (ESR) and Fourier Transform infrared (FTIR) spectroscopic techniques. The ESR spectrum observed for gamma irradiated MA-EMA copolymer has shown resolved hyperfine (hf) pattern at lower temperatures (77K) while at higher temperatures the spectrum is appeared to be broadened. Fourier Transform Infrared spectra of pure and gamma irradiated MA-EMA copolymer have been recorded for the copolymer …

Optical and Microstructural Changes in 5(6)-Carboxyfluorescein Doped PVA
Abstract: AbstractThe effect of 5(6) Carboxyfluorescein dye on microstructural and optical properties of a Poly(vinyl alcohol) (PVA) have been studied by using FTIR and UV-Visible absorption techniques. FTIR spectral result shows the possible interaction between the dye and PVA. The UV-Visible spectra shows three absorption bands (around 227nm, 310nm and 450nm) and from the observed optical band edges in the UV-Visible spectra, three optical band gaps and three activation energies for …
