Extended Abstract Direct ink writing or printing techniques offer an attractive alternative for satisfying the demanding design rules and form factors required for metallic electrodes in printed electronic and optoelectronic devices. Traditionally, the micro-fabrication of conductive patterns by electroplating and etching processes accompanied by lithography is time-consuming and expensive proc...

Differing from the hot-pressing method in the manufacturing of traditional wood-rubber composites (WRCs), this study was aimed at fabricating WRCs using rubber processing to improve water resistance and mechanical properties. Three steps were used to make WRCs, namely, fiber-rubber mixing, tabletting, and the vulcanization molding process. Ninety-six WRC panels were made with wood fiber content...

Exposure to potentially alkylating in a rubber factory was measured by determining thioether concentrations in urine samples collected at the end of work on a Friday. The study population consisted of the total work force (113) in the production departments of a factory, and office clerks (111) in two factories of the same company. The highest excretion of thioethers was detected in female work...

Low-temperature reactive mixing of controlled electron beam modified Polytetrafluoroethylene (PTFE) nanopowder with Ethylene-Propylene-Diene-Monomer (EPDM) rubber produced PTFE coupled EPDM rubber compounds with desired physical properties. The radiation-induced chemical alterations in PTFE nanopowder, determined by electron spin resonance (ESR) and Fourier transform infrared (FTIR) spectroscop...

Asphalt crumb rubber is a type of pavement material formed by mixing asphalt cement with that derived from recycled tires. This eco-friendly approach aids in waste reduction and promotes environmental preservation incorporating materials into construction. The study aimed to examine the behavior mixtures modified rubber, made blending tire-derived cement. Adding improved performance mixtures, 8...

An economical bioreactor designed for evaluating the biogas potential of particulate biomass is described. The bioreactor uses a simple stirring apparatus, called the Bordeaux stirrer, to enable gas-tight mixing of fermentation cultures. The apparatus consists of a low-rpm motor connected to a bent steel stir rod, which is placed in a length of flexible plastic tubing inserted through a rubber ...
