Binding substances

Pitch In manufacture of blocks of fuel consisting of coal, coal dust, coke or slurry with pitch as a binding substance... 

When there is a limitation of the phosphorus content in detergents of 1%, then addition of phosphonates can act as an alternative solution in combination with other polyvalent ion-binding substances. Especially when magnesium is a cause of water hardness the zeoliths can form precipitations. But phosphonates, like hydroxyethanephosphonic acid (HEDP) and ethylenediaminetetra-methylenephosphonic acid (EDTMP), are able to sequester magnesium ions as well. 

Most adhesive preparations consist of at least two main components an adhesive and a solvent. The adhesive is the binding substance that, when dry, attaches and joins together adjacent surfaces, or sizes (covers and seals) porous surfaces. Water was, for many millennia, practically the only solvent used in adhesive preparations. Adhesives soluble in water form solutions and, if insoluble, become suspended in the water, usually in such concentration as to render the preparation viscous and tacky. As well as the adhesive and the solvent, a variety of additives have often been added to adhesive preparations so as to improve their spreading properties or modify other qualities. Additives, which increase the viscosity of the preparations, are known as fillers, while those that increase their volume are referred to as diluents (Eagland 1988 Masschelein-Kleiner 1985). 

The electrodes for examination were produced by smearing of suspension of active materials in the solution of binding substance -po 1 yviny 1 idcncfluoride (PVDF) - on the metal substrate by means of applicator "Doctor Blade" by Hohsen Corp. N-methyl-2-pyrrolidone was used as the solvent for the binding substance. 

Presence of competitive binding substances (e.g., specific receptor sites in tissues bind drugs). 

In these experiments, synthetic zeolites of the faujasite-type without binding substance were used. Calcium and nickel-calcium samples in ionic form were obtained by ion exchange under conditions ensuring stability of the crystal structure (5). Platinum addition was carried out by ion exchange with Pt(NH3)6Cl4 (6). 

Some metal binding substances, including 8-hydroxyquinoline and sodium dimethyldithiocarbamate, damage the islets of Langerhans and cause diabetes in experimental animals181). 

When van Rij and co-workers (3) infused patients with various amino acid preparations, they found urinary zinc excretion to be higher with a sugar-containing preparation than when they used the same preparation without sugar. A unique zinc-binding substance was present in the sugar-containing solution and in the urine of patients infused with it. 

Although quantitative measures of browning in total diets have not, to our knowledge, been made, most conventional diets contain substantially more browned foods than the diet used in this study. Nevertheless, differences in 65Zn retention and in the molecular-weight distribution of urinary zinc-binding substances were seen. It is likely that these differences would be less subtle if the experimental diet were more highly browned. Future experiments in this laboratory will examine this question. 

The piezo-electric effect of deformations of quartz under alternating current (at a frequency in the order of 10 MHz) is used by coating the crystal with a selectively binding substance, e. g. an antibody. When exposed to the antigen, an antibody-antigen complex will be formed on the surface and shift the resonance frequency of the crystal proportionally to the mass increment which is, in turn, proportional to the antigen concentration. A similar approach is used with surface acoustic wave detectors [142] or with the surface plasmon resonance technology (BIAcore, Pharmacia). 

Another technique of solid foam preparation is based on gas formation in a melted polymerising bulk or in concentrated water suspension of binding materials (cement, gypsum, lime), occurring after physical or chemical processes. It is also possible to incorporate air in a polymerising or solidifying substance bulk. For example, cellular-concrete represents a material in which gas bubbles are uniformly distributed in the bulk. The material produced when suspensions of binding substances are mixed with a foam is called cellular (foam) concrete. If the gas is formed in the concrete bulk as a result of a chemical reaction, for instance, in the reaction of aluminium powder with the liquid phase of the concrete solution, a gas-concrete is produced. 

Formulations of lithium carbonate tablets with various binding substances have been discussed (518). 

There is no evidence for any toxic effects of chromium(III), which is an essential trace element in mammals (required daily intake 50-200 /tg) and participates in glucose and lipid metabolism. In the low-molecular-weight Cr binding substance (LMWCr), an oligopeptide, a tetranuclear Crm carboxylate complex may be present.44...
