Static and dry friction due to multiscale surface roughness.
It is shown on the basis of scaling arguments that a disordered interface between two elastic solids will quite generally exhibit static and dry friction (i.e., kinetic friction which does not vanish as the sliding velocity approaches zero) because of Tomlinson-model instabilities that occur for small-length-scale asperities. This provides a possible explanation for why static and dry friction ...
متن کاملDeath due to resistance to enterococci in the intensive care unit: case report
Background & Aim: Hospital infections are one of the major problems in intensive care units and in many cases increases the mortality rate. Case report: A 68-year-old man is being treated after cervical vertebra fracture and fracture and is treated with linezolid following antibiotic resistance. Following the non-observance of the isolated contact points, this resistance was transferred to the ...
متن کاملTitanium Dioxide Nanoparticles Increase Resistance of L. iberica to Drought Stress due to Increased Accumulation of Protective Antioxidants
This research was carried out to study the effect of TiO2 and nano-TiO2 on some chemical compounds in a medicinal plant Lallemantia iberica under water deficit conditions. The experiment was conducted as a factorial arrangement in a randomized complete block design with three replications. The first factor was the application of external materials as spraying with 3 levels of control, TiO2 and ...
متن کاملSurface roughness-induced speed increase for active Janus micromotors.
We demonstrate a simple physical fabrication method to control surface roughness of Janus micromotors and fabricate self-propelled active Janus microparticles with rough catalytic platinum surfaces that show a four-fold increase in their propulsion speed compared to conventional Janus particles coated with a smooth Pt layer.
متن کاملFrom Surface Roughness to Surface Displacements
This paper presents an extension to a measurement system to capture bidirectional refEectance distribution function (BRDF) values and texture maps out of images. The extension will enable the measurement of reflection effects due to surface roughness and additionally extracts a map representing local surface displacements. Different lighting conditions where used to discriminate between surface...
