Phonon transport in an initially twisted polyvinyl acetate nanofiber

Electrospinning of Continuous Nanofiber Bundles and Twisted Nanofiber Yarns

Spinning is a prehistoric technology in which endless filaments, shorter fibers or twisted fibers are put together to produce yarns that serve as key element to assemble multifarious structural designs for diverse functions. Electrospinning has been regarded as the most effective and versatile technology to produce nanofibers with controlled fiber morphology, dimension and functional components...

AN EXPLORATORY INVESTIGATION OF VISCOELASTIC NANOINDENTATION ON POLYVINYL ACETATE By

Phonon Transport in Graphene

Properties of phonons – quanta of the crystal lattice vibrations – in graphene have attracted strong attention of the physics and engineering communities. Acoustic phonons are the main heat carriers in graphene near room temperature while optical phonons are used for counting the number of atomic planes in Raman experiments with few-layer graphene. It was shown both theoretically and experiment...

Phonon Transport in Nanostructures

Recent experiments aiming to produce TiO2 nanostructures have been riddled with complications. It has been found that an undesired reaction occurs with the water used in the flaking process producing a sulphurous smell. This product suggests the production of TiOxS2−x in the layered crystal structure. This nanostructure has great potential benefits for the construction of semiconductor devices ...

Flow behaviour of polyvinyl alcohol (PVOH) modified blends of polyvinyl acetate (PVAc)/natural rubber (NR) latexes

During compounding processes, polymer latexes are mixed with various colloidal systems (in particular, PVOH) or surface-active agents to modify the flow behaviour in order to suit the manufacturing process. In this study, the flow behaviour of aqueous dispersed PVAc, NR and different mixed dispersions were investigated both in the absence and presence of PVOH as flow modifier, using an Ostwald ...
