Effect of Surface Modifications on the Meniscus Velocities of Dyed Water in PMMA Microchannels
Abstract: In this work, author has fabricated the polymethylmethacrylate (PMMA) microfluidic devices to study the effect of surface modification techniques on surface-driven capillary flow. Maskless lithography, hot embossing lithography and direct bonding technique are used to fabricate the PMMA microfluidic devices. The effect of static water contact angle on surface- driven capillary flow is studied in the fabricated devices. The effect of the arrays of square PMMA micropillars on surface-driven capillary …

Experimental Techniques to Fabricate the Microfluidic Devices
Abstract: The fluidic motion inside any microchannel is termed as the microfluidic flow. The subject of microfluidics is interdisciplinary in nature involving the principles of basic sciences and engineering. The microfluidic devices are fabricated by appropriate microfabrication techniques. Also, the inner surfaces of microfluidic devices are modified by choosing appropriate surface modification techniques depending on the device material. Also, the characterization techniques are required to determine the inner surface qualities of …

Development and Evaluation of Physical and Mechanical Properties on Talc Filled Sisal/Polyester Composites
Abstract: In recent years, research focusing on the use of natural fiber-reinforced composites has been increased and has opened up further industrial possibilities due to advantages of low density, low cost, biodegradability, abundance and renewability proffered by natural fibers. In this research, randomly oriented sisal fiber and talc filler were used to reinforce polyester matrix to produce composites of 3 mm thickness. The composites were fabricated by hand laying technique. Composite …

HYDROTROPES IN SOAP FLOTATION: A CRITICAL REVIEW
Abstract: In this study efficiency of soap flotation when the hydrotrope was used along with the flotation reagents especially collectors for different type of minerals is reviewed. It is known that for flotation of salt type minerals soaps are used as collectors. The soap collectors when used along with hydrotropes as promoters in flotation yielded better flotation efficiency along with the reduced usage of collectors (soaps). Hydrotropes the compounds that soulibilises …
