Lubrication in the cold rolling process plays a key role withstanding loads between strip and work rolls, as well ensuring high surface quality, tight geometric tolerances, large thickness reductions. Most of currently used lubricants have synthetic or semi-synthetic formulations, but research for greener alternatives, able to guarantee very low environmental impact during both preparation (use...

Both compounds have become more commonly used in dietary supplements. Stearic acid is commonly used as a binder in tablets, and it has lubricant properties. Magnesium stearate is a lubricant commonly used in tablet formulations. After achieving a homogenous blend of powdered ingredients, adding a small amount of magnesium stearate enables the powder blend particle surface to be sufficiently coa...

In this study, osteoarthritic and periprosthetic synovial fluid samples were rheologically and biochemically compared to develop a hyaluronic acid (HA) supplemented bovine serum (BS) lubricant that mimicked the properties of human joint synovial fluid. The effect of this BS + HA lubricant (50 per cent bovine calf serum + 1.5 g/l HA) on the wear rate of ultra-high molecular weight polyethylene (...

The cochlear implants consisting of electrode arrays for electrically stimulating the auditory nerve fibres have been developed to restore hearing for profoundly deaf people. The insertion of a straight electrode array into the spiral cochlear scala tympani has unfortunately been found to damage delicate structures within the inner ear such as the spiral ligament and the basilar membrane. Altho...

Water-based lubrication, due to the poor film-forming ability of water, faces challenges in achieving effective lubrication for titanium alloys. This study systematically investigates frictional performance phosphorus-based extreme pressure (EP) additives and self-emulsifying esters (SEE) on surface alloy (TB6) under different pressures temperatures. The core lubricant consists SEE with nonylph...

Triazine-based covalent organic frameworks (TriCFs) were synthesized using melamine, and cyanuric acid is a brand-new synthetic lubricant, which thermo-stable possesses lamellar structure. This article demonstrates how topological descriptors for the TriCF structure are precisely evaluated degree sum of end vertex neighbors also some molecular with multiplicative neighborhood sums evaluated. Fu...

Development and application of bio-based fluids in industrial and automotive sectors are rapidly increasing due to their non-toxic and biodegradable character unlike mineral oil-based products. Synthetic lubricant base fluid with improved high and low-temperature stability was prepared by chemical modification of epoxidized soybean oil (ESBO). The reaction was carried out in two-steps: (i) synt...
