Effect of molecular weight on fibrous PVA produced by electrospinning

Variable neighbourhood search (VNS) is a metaheuristic, or a framework for building heuristics, based upon systematic changes of neighbourhoods both in descent phase, to find a local minimum, and in perturbation phase to emerge from the corresponding valley It was first proposed in 1997 and has since then rapidly developed both in its methods and its applications In the present paper, these two aspects are thoroughly reviewed and an extensive bibliography is provided Moreover, one section is devoted to newcomers It consists of steps for developing a heuristic for any particular problem Those steps are common to the implementation of other metaheuristics

Variable neighbourhood search: methods and applications

Structural details, viscoelastic and mechanical response in blends of a vinyl alcohol-ethylene copolymer and a metallocenic ethylene-1-octene copolymer

The tensile drawing behaviour and the viscoelastic relaxations of three different copolymers of ethylene, containing 1-butene, 1-hexene and 4-methyl-1-pentene as comonomer, have been studied. The composition of the copolymers is increasingly poorer in comonomer following the above order. However, they show similar mechanical properties, both large-strain and small-strain dynamic mechanical, because the minor differences which have been found can generally be explained by the thermal and mechanical histories of the samples. Thus, it seems that the higher disrupting effect produced in the copolymer structure by the comonomers of greater size and volume is counterbalanced by the corresponding smaller concentration, and that only thermal treatment produces appreciable differences in properties.

Mechanical properties and dynamic mechanical relaxations of ethylene/alpha-olefin copolymers

The influence of two thermal treatments on the structure, morphology, and ultimate properties exhibited by isotactic polypropylene (iPP), synthesized by conventional Ziegler–Natta iPP (Z-iPP) or me

Effect of thermal treatment on the mechanical and viscoelastic response of polypropylenes incorporating a β nucleating agent

Poly (lactic acid)/D-limonene/ZnO bio-nanocomposites with antimicrobial properties

The drawing of an amorphous copolyester based on poly(ethylene terephthalate) and poly(1,4 cyclohexylene-dimethylene terephthalate) has been studied at temperatures from 20° to 100°C and various strain rates. The tensile properties, densities, and stress whitening of the stretched samples depend on whether the drawing temperature is below or above the glass transition temperature.
