The present study investigates the influence of hygrothermal ageing on the tribological behaviour of polytetrafluoroethylene (PTFE) polymer composites.Three PTFE composites along with unfilled PTFE were tested in sliding contact against Inconel 625 (a Ni-based alloy) plates in both dry and water-lubricated conditions, utilising a unidirectional pin
Abstract The utility of nanotechnology in medicine, specifically within the field of orthopedics, is a topic of extensive research.Our review provides a unique comprehensive overview of the current and Apparel potential future uses of nanotechnology with respect to orthopedic sub-specialties.Nanotechnology offers an immense assortment of novel appl
Academic global pulmonary/critical care medicine (PCCM) remains a relatively novel concept not fully embraced by all training programs, so PCCM early-career professionals may have little guidance in building successful careers in this field.To highlight various approaches used by current PCCM faculty to incorporate global health into their academic
Abstract The electrochemical and photochemical properties of graphene derivatives could be significantly improved by modifications in the chemical structure.Herein, reduced graphene oxide (RGO) was functionalized with l-arginine (l-Arg) Extracters by an amidation reaction between the support and amino acid.Deposition of a powerful ligand, l-Arg, on
Abstract Background Coverage and quality of cause-of-death (CoD) data varies across countries and time.Valid, reliable, and comparable assessments of trends in causes of death from even the best systems are limited by three problems: a) changes in the International Statistical Classification of Diseases and Related Health Problems (ICD) over time;
