Ultrasound micro-molding technology has proved useful in processing biodegradable polymers with minimum material loss. This makes this technology particularly suitable for the production of biomedical microdevices. The use of silica (SiO2) nanoparticles is also interesting because of advantages like low cost and enhancement of final properties. Evaluation of the capacity to create a homogeneous...

The structure of an oil/water emulsion is known to depend on its preparation method. Here, we test whether the preparation protocol can be used to control the morphology of ‘‘model’’ blends of immiscible polymers compatibilized by a diblock copolymer. Two preparation protocols were tested. In the ‘‘double blending’’ protocol, a droplet-matrix blend was blended with additional drop-phase fluid. ...

The use of waste materials to make eco-friendly wood-polymer composites has been explored by many researchers for academic and industrial purposes due the low cost, biodegradability, availability wood flour. Polypropylene (PP)/ground tyre rubber (GTR)/wood flour (WF) were prepared using an internal batch mixer at a temperature 165 °C 8 min, samples injection-moulded 190 with pressure 6 MPa. des...

The mechanical, viscoelastic and structural properties of starch/ poly (butylene adipate co-terephthalate) (PBAT) blown films produced by reactive extrusion were evaluated using citric acid (CA) and maleic anhydride (MA) as compatibilizers. Scanning electron microscopy images showed more homogeneous structure when CA and MA were included in the formulation. The tensile strength (MPa) was improv...

In this paper, a new structure for reactive power market is presented. Considering reactive power losses caused by active power flow in the reactive power market is the main purpose of this paper. Hence, this study tries to improve reactive power market and create fair competition in reactive power generation.

Non-catalytic hydrogenation of liquid natural rubber (LNR) via thermal decomposition 2,4,6-trimethylbenzenesulfonylhydrazide (MSH) is reported in this study. Parameter studies the reaction were performed by utilizing combination response surface methodology and central composite rotatable design (RSM/CCRD). The effects each variable interaction between two variables (i.e. MSH:LNR weight ratio t...

In this study, wood polymer composites (WPC) were produced by polypropylene (PP) as the matrix material and 30 wt% olive flour (OWF) filler material, for injection applications. Various treatments of OWF—including single treatment or co-modifications using silane treatment, heat maleic anhydride grafted (MAPP) compatibilizer—were used to improve PP/OWF compatibility mechanical properties. Struc...

reactive oxygen species (ros) are produced in many normal and abnormal processes in humans, including atheroma, asthma, joint diseases, cancer, and aging. basal levels of ros production  in  cells  could  be  related  to  several  physiological functions  including  cell proliferation, apoptosis and homeostasis. however, excessive ros production above basal levels would impair and oxidize dna, ...
