Rubber/Carbon Nanotube Nanocomposite with Hyperelastic Matrix
An elastomer is a polymer with the property of viscoelasticity, generally having notably low Young's modulus and high yield strain compared with other materials. Elastomers, in particular rubbers, are used in a wide variety of products ranging from rubber hoses, isolation bearings, and shock absorbers to tires. Rubber has good properties and is thermal and electrical resistant. We used carbon ...
متن کاملProperties of baked starch foam with natural rubber latex
Petroleum-based synthetic plastics used for making consumer articles constitute the largest non-renewable source of municipal solid waste in the United States. Containers and packaging products represent the largest group within plastic waste in municipal landfills. Efforts are being made worldwide to search for renewable and biodegradable substitutes for non-biodegradable plastics. Starch from...
متن کاملTopological quiver matrix models and quantum foam
We study the matrix models that describe the BPS bound states of branes arising from the quiver picture of the derived category. These theories have a topological partition function that localizes to the Euler character of the anti-ghost bundle over the classical BPS moduli space. We examine the effective internal geometry of D6/D2 bound states in the local vertex geometry, using BPS 0-brane pr...
متن کاملMore about the letter-frequency effect.
Recently. this journal published a study by Appelman and Mayzner (1981) in which the authors examined previous letter-recognition studies to determine whether more frequent letters were easier to recognize than less frequent letters (the letter-frequency effect). They found a discrepancy between accuracy studies and reaction time (RT) studies, with only the latter providing evidence for a lette...
متن کاملBuilding a home from foam--túngara frog foam nest architecture and three-phase construction process.
Frogs that build foam nests floating on water face the problems of over-dispersion of the secretions used and eggs being dangerously exposed at the foam : air interface. Nest construction behaviour of túngara frogs, Engystomops pustulosus, has features that may circumvent these problems. Pairs build nests in periodic bursts of foam production and egg deposition, three discrete phases being disc...
