This paper proposes techniques to fabricate synthetic gecko foot-hairs as dry adhesives for future wallclimbing and surgical robots, and models for understanding the synthetic hair design issues. Two nanomolding fabrication techniques are proposed: the first method uses nanoprobe indented flat wax surface and the second one uses a nano-pore membrane as a template. These templates are molded wit...

BACKGROUND Artificial sports fields are increasingly being used for sports. Recycled rubber from automotive and truck scrap rubber tires are used as an infill material for football grounds. There are concerns that football players may be at risk due to exposure from released compounds from rubber infill. Compounds from crumb infill may be inhaled and dermal exposure may occur. A study was perfo...

2 Executive Summary The purpose of this paper is to familiarize the reader with the paving material asphalt-rubber (A-R) by providing historical perspective on its development and obstacles to its development. A-R has been a constant and stable market for crumb rubber producers in the United States most significantly within the vicinity of Arizona, California, and Florida. Agencies use A-R beca...

The enrichment and isolation of thermophilic bacteria capable of rubber [poly(cis-1,4-isoprene)] degradation revealed eight different strains exhibiting both currently known strategies used by rubber-degrading mesophilic bacteria. Taxonomic characterization of these isolates by 16S rRNA gene sequence analysis demonstrated closest relationships to Actinomadura nitritigenes, Nocardia farcinica, a...

To compare the Immediate skm test reactivity ofvanous latex (natural rubber) surgical and cleanmg gloves, pnck tests were performed on 40 latex-allergic persons, 26 of whom were sensitized by surgical and 14 by cleanmg latex gloves. 6/17 surgical gloves tested and 1/2 cleanmg gloves caused positive reactions m almost all (over 87%) of the allergic subjects. In contrast, the frequencies of posit...

Along with the developing technology in rubber industry, use of natural and synthetic rubbers as well liquid has increased significantly recent years. The formulation tread compound, which directly affects performance a tire, is generally produced from rubbers. Intensive scientific studies have been carried out on because they reduce consumption process oils used tire production phase increase ...
