Lamotrigine is a substituted asymmetric triazine. It is a white to pale cream-coloured powder. It is slightly soluble in ethanol and chloroform, and very slightly soluble in water. The pKa of lamotrigine at 25°C is 5.7. Each Lamictal Dispersible/Chewable tablet also contains calcium carbonate, hydroxypropyl cellulose, aluminium magnesium silicate, sodium starch glycollate, povidone, saccharin s...

A natural biosorbent containing amine functional groups, chitosan, and a novel sorbent, chitosan-immobilized sodium silicate, were prepared and utilized for the selective sorption of As(V) from waters prior to its determination by atomic spectrometric techniques, namely, hydride generation atomic absorption spectrometry (HGAAS) and inductively coupled plasma mass spectrometry (ICP-MS). Chitosan...

We propose a new method using coarse-graining and molecular dynamics to calculate structural and mechanical properties for sodium silicate glasses at different scales. Using this method we were able to describe the mechanical behavior of the material, this way a new constitutive model was developed which could be used in continuum calculations.

In order to reduce the iron impurities in magnesite ore and improve purity of magnesium products, difference floatability between limonite has been studied by using mixtures with a collecting agent—KD (cationic amine collectors, containing soluble components). Sodium hexametaphosphate, pH, sodium silicate, carboxymethyl cellulose were used as regulators. Adsorption mechanisms reagents on minera...

Geopolymer concrete mixes were cast using fly ash, kaolin, sodium hydroxide, potassium hydroxide, sodium silicate and aggregates. Portland cement concrete (M30) was used as a reference sample. The effect of silica fume, temperature (40 °C, 60 °C, 80 °C, 100 °C and 120 °C), sodium and potassium hydroxides and different superplasticizers on the compressive strength are reported [1]. Maximum stren...

The urinary excretion of silicon in the rat was found to be enhanced beyond normal levels by the administration of various chemical forms of silicon. The excretion was enhanced to a much greater degree by the administration of ethyl silicate than by magnesium trisilicate, sodium metasilicate, or water glass. The tolerance level of rats to sustained daily doses of ethyl silicate fed via stomach ...
