india has large resources of natural fibres such as banana, khus, sisal, korai grass,talipot, palm leaf, coconut, pineapple, screwpine, golden grass, jute and sabaiamong others. in the past, trade of the village folk depended on harvesting fibresgrown in their villages. natural fibers have recently gaining attraction of researchersdue to their low cost eco-friendly and biodegradability characte...

A new contactless ultrasonic sonotrode method was previously designed to provide cavitation conditions inside liquid metal. The oscillation of entrapped gas bubbles followed by their final collapse causes extreme pressure changes leading de-agglomeration and the dispersion oxide films. forced wetting particle surfaces degassing are other mechanisms that considered be involved. Previous publicat...

OBJECTIVE This study aimed to improve the functional properties of anatomically-shaped meniscus constructs through simultaneous tension and compression mechanical stimulation in conjunction with chemical stimulation. METHODS Scaffoldless meniscal constructs were subjected to simultaneous tension and compressive stimulation and chemical stimulation. The temporal aspect of mechanical loading wa...

epoxy – polysulfide copolymers without or with low amounts of epoxy in their structure have poor mechanical properties in oxidative curing system.to strengthen the mechanical properties of polysulfide elastomer inclusion of epoxy resin (epon828) as hard segment was studied. ft-ir spectroscopy and rheometry were used to verify the formation of epoxy-polysulfide copolymer.  results obtained from ...

adhesive bonding technology is being used in a variety of modern industries, including the automotive, aerospace, maritime, construction, defense and so on. on the other side, polymeric nano - composites attracted both academic and industrial interests in the past decades. the scope of this paper is experimental investigation on the effects of the addition of alpha-alumina nanoparticles to the ...
