plasma electrolytic oxidation (peo) was performed on a 1010 aluminum alloy. to achieve thenanocomposite structure, si3n4 nanoparticles were added into the electrolyte. in an alkaline aqueoussuspension (silicate-based), the effect of adding niso4 on the applied voltage, microstructure,composition, wear, and corrosion resistance of peo coatings was investigated using scanningelectron microscopy (...

Zeolites are a large family of crystalline microporous materials with, mainly, silicate and aluminosilicate composition. Each topology can only be synthesized in specific range aluminum content, Al/(Si + Al), within the interval [0–0.5], this cannot, general, predicted for each structure. Aluminum organic structure directing agents (OSDAs), among others, act together obtaining zeolite phase und...

[1] Brillouin scattering measurements on aluminous magnesium silicate perovskite, arguably the most abundant phase in Earth, have been performed to 45 GPa in a diamond anvil cell at room temperature, using methanol-ethanol-water and neon as pressure transmitting media. The experiments were performed on a polycrystalline sample of aluminous MgSiO3 perovskite containing 5.1 ± 0.2 wt.% Al2O3. The ...

Objective. The present study assessed the chemical elements in two novel calcium silicate-containing root canal sealers, BioRoot RCS and Well-Root ST, compared to a calcium silicate-containing root canal sealer that has been on the market for several years, MTA Fillapex, and epoxy resin-based sealer AHPlus. Material and Methods. The sealers were mixed and manipulated according to the manufactur...

During design and construction of the SLAC polarized LEED (PLEED) system, a search was made for a dependable gear, bearing, and lubrication sysLem for .the. computer-controlled Faraday cup used to measure diffracted beams. Components must be nonmagnetic, bakeable to 250” C, and at room temperature must operate at pressures in the 1O-9 to VYio Pa range. A test system was constructed which incorp...
