Composite materials based on a polymer mixture -low density polyethylene and polybutylene terephthalate -have been obtained investigated. To improve the compatibility of two thermodynamically incompatible polymers, compatibilizer was used, which is modified with maleic anhydride. It found that compatibilization low polyethylene/polybutylene terephthalate, leads to significant change in basic ph...

reactive oxygen species (ros)plays an important role in sperm motility. the physiological generation at low concentration induces beneficial effects on sperm functions and plays a significant role in sperm metabolism. meanwhile, the excessive generation of reactive oxygen species can overwhelm protective mechanism and triggers changes in lipid and protein layers of sperm plasma membrane, which ...
