Effect of three different antioxidants on the shear bond strength of ...Materials and Methods: Ninety recently extracted human premolars were divided into six groups of 15 teeth each. Except Group I (negative control), the labial enamel surface of all specimens in the other groups were bleached with 37.5% hydrogen peroxide. After bleaching, Group II specimens were stored in artificial saliva for 3weeks before composite bonding. Immediately following bleaching; Groups III, IV, and V specimens were treated with antioxidants 10% sodium ascorbate, ...

Antibacterial, antioxidant and optical properties of edible starch ...In this study Thymus kotschyanus EO concentrations ranging from 0 to 2.0%, incorporated in starch-chitosan composite (S-CH) film were used. Antimicrobial and antioxidant properties significantly increased with the incorporation of EO (p < 0.05). Incorporating EO, increased total color differences (DE), yellowness index (YI) and whiteness index (WI) which were significantly higher than control and its transparency was reduced. Our results pointed out that the incorporation of Thymus&nbsp;...

Research on Technology of Wood-Plastic Composites - Scientific.netwood-plastic composites were produced by heating, blending and extruding with recycled plastics and wood fiber as chief materials and some thermoplastic resin as the additive. The compounding formula and producing craft were researched and optimized. The influence of the ratio of wood fiber and additives was examined. wood-plastics composites with excellent performance were produced.
