We describe herein how to control the orientation of polymer nanowrinkles and nanofolds with large amplitudes. Nanowrinkles were created by chemically treating thermoplastic polystyrene sheets to form a thin skin layer and then heating the substrate to relieve strain. By manipulating the strain globally and locally in the skin layer, we could tune whether wrinkles or folds formed, as well as th...

The influence of laser surface structuring on the formation and internal strength electrodeposited ZnNi coatings steel sheets was investigated. Surface by extended direct interference patterning (xDLIP) used to modify cohesive in layer. An SEM analysis crystal structures shows perpendicular nucleation during layer areas crosslinked crystalline structures, which results an interlocking within in...

Graphene-based sheets show promise for a variety of potential applications, and researchers in many scientific disciplines are interested in these materials. Although researchers have developed many ways of generating single atomic layer carbon sheets, chemical exfoliation of graphite powders to graphene oxide (GO) sheets followed by deoxygenation to form chemically modified graphene (CMG) offe...

A novel method for transferring thin, large-area polymer layers from a mould and its subsequent bonding to a destination substrate is presented here. Buoyancy is used for transfer via floatation to allow the release of internal stress in the polymer and to avoid induced strain. Additionally, floatation leads to wrinkle-free contact between the polymer layer and its destination substrate, an imp...

In this present study the double layers structure model of extended Korteweg-de Vries(K-dV) equation will be obtained with the help of the reductive perturbation method, which admits a double layer structure in current plasma model. Then by using of new analytical method we obtain the new exact solitary wave solutions of this equation. Double layer is a structure in plasma and consists of two p...

Sections and freeze-fractured preparations showed an S layer on the surface of Pseudomonas-like strain EU2. Polyacrylamide gel electrophoresis of cell envelopes extracted with 1% sodium dodecyl sulfate (SDS) at room temperature showed three proteins (45K, 55K, and 110K). The 55K protein was identified as the S-layer protein. Incubation in 1.5 M guanidine hydrochloride removed the S layer from c...

Although there are many advantages to using rubber produce reinforced concrete substrates, still few applications for rubberized substrates like beams, where the mechanical properties of rubber-infused concrete, such as flexural strength, begin decline. On other hand, strengthening constitutes a sizeable portion structural uses externally carbon fiber polymer (CFRP) sheets when used strengthen ...
