Particle composites are materials reinforcement of which is formed by non fibrous particles. The particle size is in all directions equal. The properties of polymeric particle composites are defined by the synergic sum of the matrix properties and the filler properties. The polymeric particle composite, the filler of which was the waste in form of sawdust, chips and grit blasted material coming...

The intestinal submucosal layer has a special interest in view of its commercial use in sausage casings and also due to its importance in any study of normal and pathological changes in the human intestine. Although the submucosal layer has long been known to be a collageneous structure, no detailed report has been published for the isolation of highly pure submucosal collagen together with its...

Bioactive polymeric materials based on calcium phosphates have tremendous appeal for hard tissue repair because of their well-documented biocompatibility. Amorphous calcium phosphate (ACP)-based ones additionally protect against unwanted demineralization and actively support regeneration of hard tissue minerals. Our group has been investigating the structure/composition/property relationships o...

Dispersion of nanomaterials in polymeric matrices plays an important role in determining the final properties of the composites. Dispersion in nano scale, and especially in single layers, provides best opportunity for bonding. In this study, we propose that by proper functionalization and mixing strategy of graphene its dispersion, and bonding to the polymeric matrix can be improved. We then ap...

There has been growing interest in the subject of drug delivery and the design and evaluation of controlled-release systems. The simplest way to control the release of an active agent is to disperse it in an inert polymeric matrix. Controlled-release systems are of interest because they are technologically simple, relatively cheap, and practically unaffected by physiological changes. In this st...

In this study, the effect of hygrothermal conditioning on the moisture diffusion properties of the fabric composite (glass fiber/epoxy resin) was investigated. The water uptake of the specimens conditioned in humid environment at different relative humidities (0, 60 and 96 % r.h) at constant temperature (60°C) was evaluated by weight gain measurements. The moisture diffusion properties of the f...

Major advancements are needed in the thermochemical energy storage (TCES) field to bring technology commercial levels. The current research strategies focused on improving heat and mass transfer using different supporting materials achieve mechanical integrity during storage. However, these still under development, they have not overcome lab scale yet. This work explores novel matrices expand m...

Here we report a droplet microfluidic method to prepare a novel type of polymeric microbeads with monodispersity and macroporosity, and investigate their application as immunological biosensors for the detection of biological species. The matrix of such microbeads is based on macroporous monolithic textures configured with tailored pores ranging from hundreds of nanometers to a few microns with...

the main objective of this study was to produce ldpe active films containing metallic nanoparticles (ag, zno and cuo) and to investigate their physical, mechanical and anti-microbial characteristics. three types of metallic nanoparticles at concentrations of 1% (w/w) were added to low density polyethylene (ldpe) and the films were prepared using melt extrusion technique. sem results indicated r...

a bionanocomposite film was developed by nanoclay incorporation to chitosan films, using a solution casting method and the effects of nanoclay concentration (0.5, 1.0, and 3% w/w) on the physical and mechanical properties of the chitosan films were evaluated. moreover, x-ray diffraction (xrd), scanning electron microscopy, and fourier transform infrared spectra (ftir) were used for studying mic...
