The tooth whitening process is intended to restore the original color of teeth. It consists of the application of oxidizing agents, including hydrogen peroxide. Although these products considerably improve the color of teeth, their effects on other properties of enamel are not fully understood. This work aimed to study the effects of hydrogen peroxide concentration on hydrophilicity, roughness, morphology,...
Commercialization of superhydrophobic surfaces remains rather limited due to the high costs of many fabrication processes and the poor understanding of the long term stability of their non-wetting properties. In this study, degradation of a recently developed superhydrophobic nanocrystalline Ni-PTFE composite made by electrodeposition was evaluated by a linear abrasion test on SiC abrasive media....
Aqueous suspensions containing different concentration of nano-TiO2 (50nm) are prepared, in which sodium polyacrylate (PAAS) as the dispersant is used. Their wettability and tribological properties are discussed with Dataphysics OCA50 contact angle measurement device and the MRS-10A four-ball tester, respectively. The rubbed surfaces after friction tests are also analyzed by scanning electron microscope...
Superhydrophobic surfaces that mimic surfaces found in nature, such as the lotus leaf, are an attractive research topic in various fields of study because of their numerous applications. More recent studies have focused on superhydrophobic surfaces that reduce or completely stop the accretion of ice and snow on power lines and aircraft that operate in cold regions. The superhydrophobic phenomena is...
The effects of snow temperature, wax molecular chain length and position along the ski on the wear of ski waxes due to friction on snow were analyzed in this work. Wear was induced on a linear snow tribometer positioned inside a cold chamber over a length of 9.35km. Every 850m, the waxed ski bases were analysed using FTIR-spectrometry and contact angle measurements. The deformation of the snow was...
