acrylonitrile butadiene rubber (nbr) composites are prepared from waste nylon 66 short fiber using a two-roll mill mixer. the effects of fiber content and bonding agent on the mechanical and morphological properties of the composites are studied. the curing characteristics of the composites have been studied by using cure rheometer. the cure and scorch time of the composites decrease while cure...

background: surface properties of a biomaterial could be critical in determining biomaterial’s biocompatibility due to the fact that the first interactions between the biological environment and artificial materials are most likely occurred at material’s surface. in this study, the surface properties of a new nanocomposite (nc) polymeric material were modified by combining plasma treatment and ...

The polysialylation of neural cell adhesion molecule (NCAM) evolved in vertebrates to carry out biological functions related to changes in cell position and morphology. Many of these effects involve the attenuation of cell interactions that are not mediated through NCAM's own adhesion properties. A proposed mechanism for this global effect on cell interaction is the steric inhibition of membran...

The aim of this study was to improve the adhesion performance of plasticized polyvinyl chloride (PVC) coatings on steel substrates by using nanoparticles. For this purpose, the PVC plastisol with different concentration of nano-silica was prepared and applied to bond steel joints. The adhesive strength of the joints was determined by single-lap shear test. Moreover, mechanical properties and mi...

introduction: batter coating is a new technology to reduce fat content of fried foods. the ingredients and flowproperties of batter are the most important parameters to determine the performance of batter coating and quality of the final product. among batter additives, proteins can be used as an important and effective component, because of their emulsifying properties, water absorption, and b...

Atomic Force Microscopy (AFM) indentation on living cells in physiological medium is a well established technique used for investigation of the cell mechanical properties at nanoscale. However, interpretation of the experimental data obtained in such experiments is rarely a trivial task. This is happening because living cells have a complex response to the applied mechanical stress, response th...

Abstract Hydrophilic polymer coatings on artificial implants generate excellent tribological properties. The friction properties of are affected by salt ion factors. Herein, the atomic force microscopy (AFM) was used to show that superlubricity achieved between poly(vinylphosphonic acid) (PVPA)-modified Ti6Al4V and polystyrene (PS) microsphere probe lubricated with monovalent solutions (LiCl, N...

Geckos owe their remarkable stickiness to millions of dry setae on their toes, and the mechanism of adhesion in gecko setae has been the topic of scientific scrutiny for over two centuries. Previously, we demonstrated that van der Waals forces are sufficient for strong adhesion and friction in gecko setae, and that water-based capillary adhesion is not required. However, recent studies demonstr...

Cell adhesion is essential in cell communication and regulation, and is of fundamental importance in the development and maintenance of tissues. The mechanical interactions between a cell and its extracellular matrix (ECM) can influence and control cell behavior and function. The essential function of cell adhesion has created tremendous interests in developing methods for measuring and studyin...
