Frictional melting of gabbro under extreme experimental conditions of normal stress, acceleration and sliding velocity
Understanding the physics of earthquake slip helps to improve seismic hazard predictions. The occurrence of quenched frictional melts along exhumed fault zones (pseudotachylytes) provides unequivocal evidence of ancient seismic slip along these faults [Sibson, 1975]. In order to better understand the evolution of friction (the ratio of shear stress over normal stress) during meltgenerating slip...
متن کاملExperimental design study of RB 255 photocatalytic degradation under visible light using synthetic Ag/TiO2 nanoparticles: Optimization of experimental conditions
In the present study, silver-doped TiO2 (Ag/TiO2) nanoparticles were prepared by various Ag doping (wt%) and a combination of sol-gel and ultrasound irradiation. Ag/TiO2 nanoparticles were characterized by energy-dispersive X-ray analysis (EDX), scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques. Based on the Taguchi method, photocatalytic...

متن کاملFriction and wear behavior of human teeth under various wear conditions
Previous reports have described the differences in the friction and wear behavior between different zones of human teeth. The objective of this research was to study the friction and wear behavior of human teeth under different wear conditions to extend the understanding of the tooth wear process, as well as to provide a more rational explanation for wear mechanism of teeth. Two typical wear te...
متن کاملIndustrial Noise and Tooth Wear - Experimental Study
UNLABELLED Tooth wear is a complex multifactorial process that involves the loss of hard dental tissue. Parafunctional habits have been mentioned as a self-destructive process caused by stress, which results in hyperactivity of masticatory muscles. Stress manifests itself through teeth grinding, leading to progressive teeth wear. The effects of continuous exposure to industrial noise, a "stress...
