Magnesium lignosulfonate and kraft lignin were activated by different oxidizing agents for use in phenolic resin composites used for the production of abrasive components. The physicochemical properties of the oxidized materials were analyzed by Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), dynamic mechanical-thermal analysis (DMTA) and inverse gas chro...
Influence of topographical features on mechanical properties of 0.1 wt % Multi-Layer Graphene (MLG)/clay-epoxy nanocomposites has been studied. Three different compositions were made: (1) 0.1 wt % MLG-EP; (2) 0.1 wt % clay-EP and (3) 0.05 wt % MLG-0.05 wt % clay-EP. The objective of making hybrid nanocomposites was to determine whether synergistic effects are prominent at low weight fraction of...
Inhalation of silica dust is associated with pulmonary fibrosis. Therefore, substitute abrasive materials have been suggested for use in abrasive blasting operations. To date, toxicological evaluation of most substitute abrasives has been incomplete. Therefore, the objective of this study was to compare the pulmonary toxicity of a set of substitute abrasives (garnet, staurolite, coal slag, spec...
One of the causes of abrasive wear is the use of abrasive tooth pastes and tooth brushes. This may lead to dentin sensitivity if exposed.The aim of this study is to examine 1,526 upper anterior and premolar teeth for evidence of abrasive wear. The segment of teeth were selected because of their preeminence in the smile line.1,526 upper anterior and premolar teeth were examined using key-feature...
The dentifrices currently available in the marketplace contain many anticariogenic substances, fluoride and abrasives aimed to better clean the dental surface, remove dental plaque, improve salivary flow and its buffer capacity and reduce colonies of bacteria such as S. mutans, the causative agent of dental caries. The objective of this study was to evaluate the possibility of adequately removi...
Results from experiments on the removal of copper using chemical mechanical polishing ~CMP! by alumina abrasives suspended in deionized water are reported. The experiments were carried out in a benchtop polishing tool using IC1000 perforated pads and SUBA 500 pads. The removal rate was measured over a good range of values of the relative velocity and pressure, and for different values of the ab...
