Effects of Filler Functionalization on Filler-Embedded Natural Rubber/Ethylene-Propylene-Diene Monomer Composites.

Natural rubber (NR) presents a number of advantages over other types of rubber but has poor resistance to chemicals and aging. The incorporation of ethylene propylene diene monomer (EPDM) into the NR matrix may be able to address this issue. Mineral fillers, such as carbon black (CB) and silica are routinely incorporated into various elastomers owing to their low cost, enhanced processability, good functionality, and high resistance to chemicals and aging.

Phlogopite-Reinforced Natural Rubber (NR)/Ethylene-Propylene-Diene Monomer Rubber (EPDM) Composites with Aminosilane Compatibilizer.

Rubber compounding with two or more components has been extensively employed to improve various properties. In particular, natural rubber (NR)/ethylene-propylene-diene monomer rubber (EPDM) blends have found use in tire and automotive parts. Diverse fillers have been applied to NR/EPDM blends to enhance their mechanical properties.

Vertical distraction osteogenesis using a titanium nitride-coated distractor.

Objectives: The purpose of this study was to examine the effect of using a titanium nitride (TiN)-coated vertical distractor on osseointegration after implantation.

Study Design: Four adult mongrel dogs, weighing 9-10 kg, were used in this study. The lower premolars were extracted, and vertical distraction was performed after 10 weeks using 8 distraction devices (left, 4 titanium; right, 4 nitrified).

Cadmium bioaccumulation and detoxification in the gill and digestive gland of the Antarctic bivalve Laternula elliptica.

Exposure to a sublethal concentration of cadmium (Cd; 50 microg L(-1)) resulted in significantly increased Cd concentrations in the gill and digestive gland of the Antarctic bivalve Laternula elliptica. Continuous accumulation of Cd in the two organs during the 14-day exposure period was associated with sequestration of Cd to both the soluble cytosolic and insoluble particulate cell fractions. However, the contribution of each cell fraction to Cd sequestration differed between the two organs; in the gill, a larger portion of Cd was associated with the insoluble fraction, while in the digestive gland, both the soluble and insoluble fractions sequestered similar amounts of Cd.
