Abstract Lubrication is a procedure that involves the use of chemical called lubricant to reduce wear on surfaces are in relative motion with each other. It aids transmission pressure created between opposing surfaces. Lubricants serve as anti-friction agents. They allow for flat-level operations by retaining superior machine functionality and reducing likelihood recurring breakdowns. In today'...

introduction: the aim of this in vitro study was to evaluate the effect(s) of three canal lubricants i.e. sodium hypochlorite, rc-prep as the paste form of ethylenediaminetetraacetic acid (edta) and aqueous edta, on the occurrence/incidence of fracture, deformity and metal slivering of protaper rotary instruments. methods: a total of 120 mesial canals ( i.e. mesiobuccal and mesiolingual) of fir...

Abstract Lubricants are often contaminated by water in different ways. Water-polluted lubricants extremely accelerate wear corrosion, leading to the deterioration of lubricity performance. Recently, multiphase media superwettability has been developed endow one surface with compatible functions, such as on-demand separation oily wastewater. However, realizing robustness dual superlyophobic solv...
