In order to be exploitable for extraction and purification of proteins/enzymes, RMs should exhibit two characteristic features. First, they should be capable of solubilizing proteins selectively. This protein uptake is referred to as forward extraction. Second, they should be able to release these proteins into aqueous phase so that a quantitative recovery of the purified protein can be obtained, which is referred to as back extraction. A schematic representation of protein solubilization in RMs from aqueous phase is shown in Fig. 2. In a number of recent publications, extraction and purification of proteins (both forward and back extraction) has been demonstrated using various reverse micellar systems [44,46-48]. In Table 2, exclusively various enzymes/proteins that are extracted using RMs as well as the stability and conformational studies of various enzymes in RMs are summarized. The studies revealed that the extraction process is generally controlled by various factors such as concentration and type of surfactant, pH and ionic strength of the aqueous phase, concentration and type of CO-surfactants, salts, charge of the protein, temperature, water content, size and shape of reverse micelles, etc. By manipulating these parameters selective sepa-... [Pg.129]

Synthesis of CdS has been performed by using cyclohexane, isooctane or decane as the bulk solvent. The data are compared to those obtained with isooctane. Figure 3.4. shows the absorption onset and the CdS diameter obtained at various water contents, using Cd(N03) reactant (Fig. 3.4.4A and B) or functionalized surfactant Cd(AOT)2 (Fig. 3.4.4C and D). At low water content, w < 10, similar sizes are obtained, whatever bulk solvent is used. These indicate that for low water content, size control is not governed by exchange micellar rate but only by preparation mode and by the nature of ions in excess (Cd2+ or S2 ). [Pg.225]

It is clear from the above discussion that the rheological properties of FCOJ will depend on the °Brix, pulp content, size and shape of the pulp particles, and pectin content of FCOJ sample, and the temperature at which the data were obtained. Carter and Buslig (1977) studied particle size distribution in commercial frozen FCOJ samples. Mizrahi and coworkers conducted systematic studies on FCOJ that they described as a physicochemical approach (Mizrahi and Berk, 1970 Mizrahi and Firstenberg, 1975 Mizrahi, 1979). They used a modified Casson equation to describe the flow behavior of FCOJ. [Pg.233]

Taking into account that the volume content, size, distribution and properties of the reinforcing boride phase practically do not change with the alloying studied here, the strengthening of the ternary and quaternary eutectic alloys should be attributed practically in full to solid- solution strengthening of the titanium alloy matrix. [Pg.265]

The organics were extensive ) characterised, as described in Chapter 4. Differences such as functional group content, size, charge, and hydrophobicity will influence the fouling behaviour if these properties are responsible for flux decline. Figure 7.20 shows a comparison of the different organics filtered through a TFC-S membrane. [Pg.247]

The physical properties that influence rheolc ical behavior are internal phase content size, shape, and panicle size distribution viscosity and rheological behavior of the continuous phase and temperature. For the case of emulsions two additional parameters, droplet deformabilily and viscosity of the dispersed phase, should also be considered. [Pg.581]

The first step in selecting a feeding system is to classify the materials that will be handled according to its density, abrasiveness, flowability, and other characteristics such as toxicity, corrosiveness, tendency to pack, and so on. Recently, efficient techniques have been developed to predict, with reasonable accuracy, the handling characteristics of a solid as function of temperature, moisture content, size distribution, friability, and flowability. Some useful empirical tests for this purpose are described by Thomson [8], The important properties measured along with the vital information they give are listed in Table 52.1. Table 52.2 discusses the flow characteristics of several classes of materials. [Pg.1026]

The content, size, and surface characteristics of silica nanoparticles were considered as main factors affecting the ciystallization behavior of poly(vinyl alcohol). Very low concentrations of silica nanoparticles (less than 0.5 wt%) accelerate the crystallization process, whereas higher silica loadings reduce the degree of crystallization. The 22-run silica nanoparticles provided the most siritable interparticle space for nucleation and crystal growth. The hydrophilic silica nanoparticles are favorable to achieve higher crystallinity due to the increased chemical affinity in the nanocomposites. With 0.5 wt% of 22-run silica nanoparticles, the crystallinity of nanocomposites was 20% higher than that of pristine PVA. ... [Pg.175]

The properties of composites depend on many factors, such as, filler content, size, shape and aspect ratio, uniform dispersion of the filler in the matrix, filler/matrix interfacial bonding, and stress/transfer efficiency through the interface [59]. Through in-situ polymerization technique, a uniform filler dispersion and effective interfacial bonding can be achieved. [Pg.140]

The shape, content, size, and size distribution of dispersed rubber particles are important factors affecting the toughening effect of PP impact modified copolymer, which relate to the micromorphological structure of the material. A wide range of characterization methods has been applied to study these rTPOs. A number of these techniques are suited to providing information on the morphology of PP copolymers where the EPR domains typically extend form a few hundred nanometers to a few micrometers in size. [Pg.37]

A8, which leads to D, = 1/(2A8). The factor of two arises because a minimum of two data points per period are needed to sample a sinusoidal wavefonn. Naturally, the broadband light source will detennine the actual content of the spectrum, but it is important that the step size be small enough to acconunodate the highest frequency components of the source, otherwise they... [Pg.1167]

The Web-based graphical user interface permits a choice from numerous criteria and the performance of rapid searches. This service, based on the chemistry information toolkit CACTVS, provides complex Boolean searches. Flexible substructure searches have also been implemented. Users can conduct 3D pharmacophore queries in up to 25 conformations pre-calculated for each compound. Numerous output formats as well as 2D and 3D visuaHzation options are supplied. It is possible to export search results in various forms and with choices for data contents in the exported files, for structure sets ranging in size from a single compound to the entire database. Additional information and down-loadable files (in various formats) can be obtained from this service. [Pg.263]
