The synthesis of aluminium hydroxide and oxyhydroxide
… synthesised directly from the various aluminium hydroxide ( Al(OH)₃ ) and aluminium oxyhydroxide (AIOOH) polymorphs. The particular oxygen sublattice of the starting material is critical in determining which phases of beta alumina are formed. Boehmite and bayerite are known to yield pure …

Crystal morphology and surface reactivity studies of calcium hydroxide
Calcium hydroxide samples, obtained as a precipitate from the mixing of solutions of sodium hydroxide with a variety of calcium salts in the optional presence of ethanol and a silylating agent, have been characterised by the techniques of nitrogen adsorption, water vapour adsorption , …

Thorium oxide dissolution kinetics for hydroxide and carbonate complexation
In order to better understand the behavior of thorium breeder reactor fuel in a repository environment, the behavior of thorium oxide was investigated. The kinetics of crystalline thorium oxide dissolution were studied under argon and argon/10% CO2 over a broad pH range in 0.1 M ionic strength …

Studies of the surface and bulk reactivity of calcium hydroxide
… available samples of calcium oxide and hydroxide were investigated. 'Fresh' and 'aged' (Le. exposed to the atmosphere) samples were characterised by Fourier Transform Infra-Red Spectroscopy, Thermo-Gravimetric Analysis, Nitrogen Adsorption, Water Adsorption, Scanning Electron Microscopy …

pH Stability of Calcium Hydroxide Preparations in a Simulated Acidic Environment
Background Calcium hydroxide (Ca(OH)₂) is a widely used intracanal medicament in endodontics, prized for its high pH, which provides antibacterial effects and promotes healing. However, its efficacy is challenged by the acidic pH of purulent exudates in infected root canals. This study aimed to …

Vibrational dynamics of aqueous hydroxide solutions studied using ultrafast infrared spectroscopy
… many of its interesting properties. Mobility of hydroxide ions in aqueous solutions is much higher compared to the ions of similar size and charge density. A proton can efficiently move from a neighboring water molecule to the hydroxide ion due to the presence of hydrogen bonds, resulting fast …

Stabilization of non-plastic soils with calcium hydroxide-calcium carbonate mixtures
… sand content and low mioa content. A calcium hydroxide-calcium carbonate weight ratio of 3 to 1 was most effective for the case where six percent additive was used. It is hypothesized that the presence of carbonate enhances pozzolanic activity in lime-stabilized non-plastic soils by increasing …

Sulfate and Hydroxide Supported on Zirconium Oxide Catalysts for Biodiesel Production
… Zirconium oxide was also impregnated with sodium hydroxide to produce basic catalysts. The best catalyst was produced when zirconium oxide was impregnated with 1.5 M NaOH and calcined at 600<sup>o</sup>C. Soybean oil was completely converted to biodiesel with 10 wt % catalyst and 1:6 oil to …

NICKEL HYDROXIDE NANORIBBONS FOR EFFICIENT WATER SPLITTING AND DIRECT METHANOL FUEL CELL
Oxygen evolution reaction (OER) and methanol oxidation reaction (MOR) are very important reactions in hydrogen harvesting system and direct methanol fuel cell (DMFC). However, these two reactions are sluggish processes, due to the multi-proton coupled reactions. In this work, we report the first …

Experimental electrochemical investigation of Si/A1 in tetra-methyl ammonium hydroxide (TMAH)
This thesis considers the micromachining of silicon for the fabrication of micro-sensors, microactuators, and microsystems. At present it is problematic to anisotropically etch silicon, in wet etchants such as TMAK while protecting deposited aluminum layers. This is especially a problem in …

Experimental investigation of anisotropic etching of silicon in tetra-methyl ammonium hydroxide
… the relatively non-toxic tetra-methyl-ammonium hydroxide (TMAH). Using a temperature-controlled etch apparatus, basic etch rate experiments on both Sid and Sin confirm and extend previous literature results. Extensive underetch experiments shows that the TMAH is qualitatively similar to other …
