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

Cr1/4NbSe2‐Single Crystal Growth and Evolution of Antiferromagnetic Correlated States
Advanced Science, EarlyView.High‐quality single crystals Cr1/4NbSe2 were synthesized and comprehensively characterized for the first time. Advanced structural, electronic, and magnetic measurements uncover a correlated antiferromagnetic state, resolving longstanding inconsistencies regarding magnetic behavior derived from earlier polycrystal studies.

Advanced Science, EarlyView.A biomimetic multi‐layer hygroscopic membrane redistributes salt toward an air‐accessible nanofiber interface, enabling rapid interfacial deliquescence while a brush‐like hydrogel promotes efficient liquid transport and storage. By decoupling vapor capture from bulk water storage, the membrane achieves fast sorption kinetics and enables rapid‐cycling ...
