Mixing liquid adding

Another important interaction that needs to be considered is the hydrophobic interaction. This can be most easily thought of in terms of two immiscible liquids such as oil and water being induced to mix by adding surfactants, to form (micro) emulsions. The exact structure of the phase formed depends heavily on the relative compositions of the various phases and the structure of the surfactant (see Figure 6.4). 

Mnk assay (using S6peptide as substrate) Each reaction contains 20 1 of immunoprecipitated or purified recombinant Mnk, as described previously, and S6 peptide (KEAKEKRQEQIAKKRRLSSLRASTSKSESSQK, final concentration = 200 pM) in kinase buffer. To initiate the reaction, 6 p of the following mix is added 5 pi 5x kinase buffer, 0.25 pi 10 mM ATP, 1 pCi [7 32P]ATP, and H20. Reactions are carried out in an orbital shaker at 30° and 900 rpm, for example, for 20 min (Mnkl) or for 5 min (Mnk2) and stopped by spotting 20 pi of the reaction mixture onto P81 paper. The filters are washed in 1% orthophosphoric acid three times. The radioactivity is determined by using a liquid scintillation counter. 

To a solution of 2-(2-carboxy-4-chlorophenoxy)acetic acid in concentrated sulfuric acid is added dropwise a mixed liquid of fuming nitric acid and concentrated sulfuric acid under stirring with keeping at a temperature below 10°C. After the addition, the reaction mixture is stirred and poured into 10 L of ice-cold water. The precipitated crystals are collected by filtration, washed with 2 L of water four times and them dried to give 2-(2-carboxy-4-chloro-6-nitrophenoxy)acetic acid. 

L tomato juice, 1 dessertspoonful of brandy and the juice of half a small lemon are mixed with a teaspoonful of Worcester sauce and one of pepper sauce. This mixture is divided between 4 glasses and small cubes cut from a ripe pear (or small slices of banana) are added. Four teaspoonfuls of horseradish are stirred with a little sour cream and a teaspoonful of this liquid added to each glass. 

A tincture is made by immersing a fresh or dried plant in full-strength alcohol or an alcohol and water mixture. Alcohol is extractive it pulls all the water out of plants into itself The resulting tincture is a mix of both water and alcohol. With fresh plants, the liquid tincture is generally equal to the amount of liquid added at the beginning. With dried plant material, especially roots, the final volume is often much less than what you started with. 

In a stirred reactor, it takes time for liquid added at the surface or at any point in the tank to become blended with the bulk of the liquid. The mixing process can be followed by observing the color change after a basic solution with an indicator is neutralized by suddenly adding a slight excess of acid. If this test is done in a 2-liter vessel, most of the solution will appear free of base in less than a second, but wisps of color may persist for 2-3 seconds until the mixing is complete. If the same test is carried out in a 5000-liter... 

Calcium formate may also be supplied in powder form and in such cases should be added to the dry batch before mixing. Liquid admixtures are generally considered easier to dispense accurately and are more readily dispersable evenly through the mix. 

The two gases are mixed by adding liquid nitrogen to one of the cold fingers for about 15 min and then closing valve C. After the system has returned to the bath temperature, valves B and C are reopened and the pressure diflFerence is observed. The mixing process is repeated until a constant pressure difference is obtained. 

Diluent dil-yo-wont [L diluent-, diluens, pp of diluere] (ca. 1721) n. A substance that dilutes another substance. In an organosol, a diluent is a volatile liquid such as naphtha that has little or no solvating effect on the resin, but serves to lower the viscosity of the mix, and is evaporated during processing. In the paint industry, a diluent is any substance capable of thinning paints, varnishes, etc. The term is sometimes also used for a liquid added to a thermosetting resin to reduce its viscosity and for an inert powdered substance added to an elastomers or resin merely to increase the volume (compare filler). 

It is difficult to mix liquid crystals directly with polymers because polymers are usually in solid state at room temperature. A solvent can be added to mix hquid crystals with polymers. We now...
