Highly Reactive .BETA.-Ca2SiO4: Preparation, Hydration and Gels.

Technical methods PREPARATION OF GELS

2 GEL SUPPORT These consist of rectangular pieces of sheet Perspex, and i inch thick, shaped to fit firmly but easily into a Perspex frame. They serve the purpose of raising the gel above the surface of the cutting platform so that it lies proud to the cutting blade (Fig. 1, E). The thickness of the gel support selected allows the precise thickness of the gel slice to be pre-determined. 3 A sha...

Hydrogen exchange and hydration dynamics in gelatin gels.

Gelatin, derived from the collagen triple helix, is the most widely used functional biopolymer and a prototype for studies of physical gels. Gelatin gels have also served as models for soft biological tissue in efforts to elucidate the molecular basis of the magnetic relaxation phenomena that govern magnetic resonance image contrast. Yet, the microstructure, hydration, and magnetic relaxation b...

Preparation of Colloidal Sols and Gels Objective

Colloidal suspensions are used to generate polymers or particles from which ceramic materials can be made by the sol-gel process. The precursors for preparation of a colloidal suspension consist of a metal element surrounded by various ligands (attached groups not including another metal). For example, common precursors for sol-gel synthesis of aluminum oxide include inorganic salts such as Al(...

Preparation of Biomolecule-Responsive Bioconjugate Gels

Preparation of highly selective solid-phase extractants for Cibacron reactive dyes using molecularly imprinted polymers.

Selective polymeric extractants were prepared for preconcentration of Cibacron reactive red dye, a dye that is often applied with Cibacron reactive blue and Cibacron reactive yellow for dyeing of fabrics. The best extractant was fabricated (in chloroform) using methacrylic acid (as monomer), ethylene glycol dimethacrylate (as crosslinker), AIBN (as initiator for polymerization), and red dye as ...
