Precursors were activated using either sodium hydroxide solution or combinations of sodium hydroxide and sodium silicate solution with varying levels of sodium and silica content.
EFB fiber was treated with boiling water, 2% sodium hydroxide (NaOH) and combination both NaOH and boiling water.
The purpose of this in vitro study was to investigate antimicrobial activity of calcium hydroxide (CH) in combination with glycerin, chlorhexidine gluconate (CHX), cetrimide, or distilled water against Enterococcus faecalis and Candida albicans.
Numerous BS biomaterials have been successfully used, such as allografts (human), xenografts (porcine, equine, or bovine, and synthetic calcium-based materials (calcium phosphates [ β-tricalcium phosphate/ β-TCP, hydroxyapatite/HA], bioactive glasses), calcium sulfate, calcium hydroxide), and a combination of these with or without the use of membrane and screws [ 6– 23].
Here we demonstrate the facile method for preparation of hollow layered triple hydroxide material in a combination of Nickel, Aluminium and Manganese with high surface area and mesoporous nature.
The results of this experiment showed that in equivalent doses, the intensity of stain produced by the solution containing ferrous fumarate is significantly lower than the stain produced by ferric hydroxide polymaltose; however the combination of the two forms of iron produced significantly lower ΔE values than equivalent doses of either.
The development of monophosphoryl Lipid A and its use in combination with aluminum hydroxide to form the ASO4 adjuvant system is a vaccine success story that represents the effective use of combination-adjuvant formulations for minimizing reactogenicity and maximizing efficacy.
Hence, the non-reactive type fly ashes can be activated in an alkali environment, such as lime, sodium hydroxide, potassium hydroxide or a combination of sodium hydroxide and sodium silicate to further improve the reactivity to participate in the pozzolanic reactions.
Regarding compressive strength, the optimum binder combination and sodium hydroxide concentration were found to be interdependent of one another.
Use of citric or lactic acids in combination with ammonium hydroxide gave a protectant solution with high pH (resulting in effective crosslinking between trehalose and borate) but a dry product with reduced pH upon rehydration (conducive to cell survival).
