Group-specific component conventional

Group-specific component is a serum protein involved with Vitamin-D transport ( ). By conventional electrophoresis three common phenotypes -1, 2-1, and 2- can be observed. [Pg.151]

H2S). In contrast to pyridine, which cannot easily discriminate between OH groups with similar acid strength, C2H4 and H2S lead to a much more specific interaction. Whatever the dealumination procedures, the structural high-frequency OH is likely to be the most acidic and its acid strength smoothly increases with the framework dealumination level. Some of the extra-framework Al-OH groups present in conventional HY treated at low temperature indeed possess a pronounced acidic character since they can interact with C2H, or H2S. Finally two components at 3738 and 3743 cm-1 appear to contribute to the Si-OH at 3740 cm-1 they correspond... [Pg.117]

In most of the examples, the isotopic methods are used essentially for analytical purposes. In this connection, their great value lies in extreme sensitivity and specificity. Many of the problems are concerned with the accurate determination of low concentrations of particular groups in polymer molecules. Another type of problem involves the determination of small weights of substances of low molecular weight formed simultaneously with polymer, or formed from polymer by chemical reactions for this purpose, the technique of isotope dilution analysis is of great value. The substances are usually present as minor components in rather complex mixtures so that determination by conventional methods would be extremely difficult. The method of isotope dilution analysis involves the addition to the mixture of a substantial quantity of the substance to... [Pg.3]

The CVD system components will be described briefly to indicate the specific features for BST CVD compared to conventional dielectric CVD system. The CVD processes for BST thin films are then dealt with from the view point of mass production compatibility. As with other CVD processes, the deposition characteristics of the BST CVD are quite dependent on the kind of precursors used. In this article, experimental results on deposition using different precursors are described. Some reported results from other groups are also summarized in order to reach a general conclusion. [Pg.207]

Extra-framework Al-OH groups are present in conventional HY treated at low temperatures. Most of these OH groups are non- or weakly acidic. However, under some specific preparation conditions, some of these extra-framework Al-OH groups behave as strong acid sites. The Si-OH band appears to be more complex than expected since a framework and an extra-framework component are involved. [Pg.134]

Fimctional foods can be developed in many forms. Conventional foods with bioactive components can be presented claiming positive health outcomes. Some may be fortified or enhanced foods, specifically created to reduce disease risk associated with a certain group of people. Although most foods have its own fimction, in this chapter "fimctionality" is ascribed to a specific phenomenon widely accepted by the scientific community involved in this field which is defined as "fimctional foods are foods and food components thatprovideahealth benefit beyond basicnutrition for the... [Pg.3]

In works/ the formation of the supramolecular systems based on branched and hydrophobized (alkyl-substituted) PEIs is revealed in both the absence and presence of cationic surfactants including those with hydroxyalkylated head groups. The latter are capable of specific interactions with other components of the systems, in particular, polymer and reagents. Hydrophobization of PEIs is found to result in a sharp increase in their solubilizing and catalytic efficiency. Besides, a marked increase in the catalysis occurs on transfer from conventional cationic surfactants to hydroxyalkylated analogues. By means of the optimization of the catalytic composition and reaction conditions a substantial 7(X)-2(XX)-fold acceleration of the phosphonate 1 is reached at neutral pH. ... [Pg.412]

The mechanism of extraction and the complexes that are formed depend on the ionic liquid concerned and are quite different than the mechanisms involved with conventional solvents. Knowledge of the mechanisms involved and the species formed would be necessary for comprehensive characterisation and modelling of two-phase extractors. Task specific ionic liquids (TSILs) could also play an important role in extractions, wherein the functional groups in both cations and anions would enhance the extraction efficiency and selectivity. Since most studies deal with single component extraction it would be extremely useful to investigate the performance of ionic liquids in the selective separation of a certain component from mixtures that simulate the actual nuclear waste. Finally, the possibility to recycle the actinides that are immobilized in the ionic hquids should be the next research area of the near future. [Pg.145]
