Purpose: Rice husk is burnt and discarded without effective use; however, it a reliable resource that can be used to extract silica from its ash (RHAS) incorporated in rubber blends as filler. The effect of Natural (NR) Acrylonitrile-butadiene (NBR) ratio NR/NBR filled with RHAS on physico-mechanical, swelling percentage specific oils (brake oil, hydraulic engine oil) toluene were studied since...
Many new biomarkers are being studied, in addition to classical biomarkers, such as chemical substances and their metabolites in blood and urine and modified enzymes. Among these new biomarkers, hemoglobin adducts are thought to be especially useful for the estimation of chemical exposures. We review here the use of biomarkers for monitoring exposures to nine substances, mainly focusing on PRTR...
In this work, black nanocarbon-loaded 0–100 parts-per-hundred (phr) PbO-filled acrylonitrile butadiene rubber (NBR)/styrene-butadiene (SBR) blend composites were prepared by using an ordinary standard mixer. Both mechanical and gamma attenuation properties of the samples investigated. Maximum tensile strength elongation at break obtained 40 phr PbO concentration. The values for mass coefficient...
