Friction vs. Area Scaling of Superlubric NaCl-Particles on Graphite
Lubricants, 2019 Structural lubricity is an intriguing tribological concept, where extremely low friction is anticipated, if two surfaces in relative motion do not share the same lattice structure and consequently instabilities originating from interlocking surface ...

Tribological Behavior of Biomass Fast Pyrolysis Fuel and Diesel Blends
Applied Sciences, 2022 The original biomass fast pyrolysis fuel was modified by an emulsification method to obtain emulsified biomass fast pyrolysis fuel with different proportions (the content of biomass fast pyrolysis fuel in the emulsified biomass fuel was 5 wt.%, 10 wt ...

Joint Lubrication with Artificial Lubricants [PDF]
Arthritis & Rheumatism, 1971 AbstractThe joint lubricating properties, in vitro, in bovine metatarsal‐phalangeal joints, of silicone fluid, methyl cellulose and polyvinyl‐pyrrolidone were compared to buffer, serum and synovial fluid. As had been previously reported, synovial fluid was almost twice as good as serum and buffer, which are equivalent in their joint lubricating ...

Finite-temperature phase diagram and critical point of the Aubry pinned-sliding transition in a 2D monolayer [PDF]
, 2017 The Aubry unpinned--pinned transition in the sliding of two incommensurate lattices occurs for increasing mutual interaction strength in one dimension ($1D$) and is of second order at $T=0$, turning into a crossover at nonzero temperatures.

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine
Advanced Materials, EarlyView.A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...
