EFFECT OF POLYMERS DISPERSING LUBRICATING GREASES ON WEAR IN DUSTY ENVIRONMENT [PDF]
Journal of the Egyptian Society of Tribology, 2011 The operating environment in cement industry is particularly severe in terms of the high ambient dust concentrations. During the severe working conditions dust concentrations of the order of 100 to 500 times higher than the normal may be encountered. The

FRICTION AND WEAR OF MOVING SURFACES IN ABRASIVE CONTAMINATED ENVIRONMENT [PDF]
Journal of the Egyptian Society of Tribology, 2011 In the present work, graphite (C) and polymethyl methacrylate (PMMA) were used as solid lubricants dispersed in lithium grease. Their effect on friction and wear of moving surfaces contaminated by solid contaminants in the cement plant is discussed. The

Journal of Applied Polymer Science, EarlyView.This work explores the use of various fillers, including eggshell powder, feather meal, peanut hulls, and sawdust to reinforce a base binder GFS90 (comprised of 90 wt.% sulfur, 5 wt.% chicken fat, and 5 wt.% sunflower oil). The resulting composites showed impressive compressive strengths ranging from 15.3 to 36.2 MPa, making them a potential ...

Advanced Physics Research, EarlyView.A pure inverse spin Hall effect (ISHE) is demonstrated in ferromagnetic Ni₈₀Fe2₀/YIG heterostructures via the longitudinal spin Seebeck effect. By employing symmetry‐controlled geometries and reference samples, anomalous Nernst contributions are quantitatively eliminated, revealing intrinsic spin–charge conversion in Ni₈₀Fe2₀.
