Effect of hydrophilized PTFE brush structure on seizure resistance in water
Nihon Kikai Gakkai ronbunshu, 2014 To prepare exhaustion of oil supplies, alternative lubricant which is good for environment will be required. Water is expected to be a suitable lubricant. However in water lubrication, high wear and seizure come to be problems because of water's low

Antiwear performance of ionic liquid+graphene dispersions with anomalous viscosity-temperature behavior [PDF]
, 2018 New dispersions of few-layers graphene (G) in 1-ethyl-3-methylimidazolium ([EMIM]) ionic liquids (ILs) with dicyanamide ([DCA]) or bis(trifluoromethylsulfonyl)imide ([TFSI]) anions have been obtained by mechanical mixing and sonication.

Removing Oxide Layers and Retaining Oxide‐Free Steel Surfaces by Polishing in Oxygen‐Free Atmosphere
Advanced Engineering Materials, EarlyView.In this study, the efficacy of wet mechanical polishing under an oxygen‐free atmosphere for deoxidation and the retention of an oxide‐free steel surface are elucidated using X‐ray photoelectron spectroscopy. The methodology proved successful; however, the results were highly dependent on the preparation of the solvents used to clean the samples after ...

Influence of asperities on fluid and thermal flow in a fracture: a coupled Lattice Boltzmann study
, 2013 The characteristics of the hydro-thermal flow which occurs when a cold fluid is injected into a hot fractured bedrock depend on the morphology of the fracture.

Weak solutions to lubrication equations in the presence of strong slippage [PDF]
, 2010 The existence of global weak solutions is proved for one-dimensional lubrication models that describe the dewetting process of nanoscopic thin polymer films on hydrophobyzed substrates and take account of large slippage at the polymer-substrate interface.

Biomimetic water-based lubrication: an exploration into vesicle lubrication
, 2023 The replacement of oil-based lubricants with water-based lubricants has been a desirable yet unrealised ambition in Tribology. The use of bio-lubricants has been previously explored; however limited advances have been achieved. Most work has focused on traditional mechanisms, with biomolecules being used to form friction reducing surface films. However,

Advanced Engineering Materials, EarlyView.This study develops sustainable MgO–C refractories using recycled materials and eco‐friendly fructose–tannin binders. The enhanced performance of citric acid as a cross‐linker and functional additives on mechanical and thermomechanical properties was examined. Characterization included strength tests, immersion trials, and microstructural and inclusion

Wet gum labelling of wine bottles [PDF]
, 1996 It is shown that bubbling on wine bottle labels is due to absorption of water from the glue, with subsequent hygroscopic expansion. Contrary to popular belief, most of the glue's water must be lost to the atmosphere rather than to the paper.

, 2010 Human hands sweat in different circumstances and the presence of sweat can alter the friction between the hand and contacting surface. It is, therefore, important to understand how hand moisture varies between people, during different activities and the ...
