Non-viscous liquids

Usually, nuclear relaxation data for the study of reorientational motions of molecules and molecular segments are obtained for non-viscous liquids in the extreme narrowing region where the product of the resonance frequency and the reorientational correlation time is much less than unity [1, 3, 5]. The dipolar spin-lattice relaxation rate of nucleus i is then directly proportional to the reorientational correlation time p... 

This relation can be converted to solve for the required orifice area at 25% overpressure for non-viscous liquids discharging to atmosphere [24]...

Gum Arabic (GA) or Acacia gum is an edible biopolymer obtained as exudates of mature trees of Acacia Senegal and Acacia seyal which grow principally in the African region of Sahe in Sudan. The exudate is a non-viscous liquid, rich in soluble fibers, and its emanation from the stems and branches usually occurs under stress conditions such as drought, poor soil fertility, and injury (Williams Phillips, 2000). 

The intermediate storage between the reaction and separation system can also help dampen out variations in composition, temperature and flowrate between the two sections (for gases and non-viscous liquids, but not solids). Variations in the outlet properties from the storage are reduced compared with variations in the inlet properties. 

Apart from non-viscous liquids the importance of obtaining a representative sample can not be overstressed. As an example flour contains very wide range of particle sizes and several different substances. It is possible to air classify flour to extract the protein. If a sample is not representative the values obtained will not be reliable.

For non-viscous liquids, where the cibove condition will be expected to be fulfilled, narrow resonances are observed, when only this source of line broadening is involved. 

Thus the selected Lewis acid catalyst, TOT, has good catalytic activity, selectivity and stability. It is a non-viscous liquid which is compatible with TOP18 and is miscible with 2,5-DHF and non polar alkane solvents. It has a very low vapor pressure so it is not lost during product distillation and catalyst recovery operations. TOT is easily synthesized at low cost and it has low toxicity (Oral LD-50 (rat), >2000 mg/kg Dermal LD-50 (rat), >2000 mg/kg). 

TiCl has been extensively used for the deposition of TiN thin films as the top electrode for Ta O dielectric capacitors as well as for barriers layers in A1 or Cu metalization because it has sufficient vapor pressure and is non-viscous liquid at room temperature. However, thermal decomposition of this precursor and elimination of Cl contamination in the film usually requires high deposition temperatures (> 600°C). As discussed later, the BST CVD process requires a low deposition temperature, less than roughly 450°C, due to issues of process integration and conformal deposition which render the, TiCl useless for this case. We need a metal-organic precursor. 

The method was used by von Wartenberg and Albrecht to determine the vapour pressures of salts, which were boiled in a platinum-iridium tube under various pressures. They found that sodium chloride formed a clear non-viscous liquid, boiling freely when heated in a quartz tube by the oxy-hydrogen blowpipe. It has been mentioned ( 10.VIID) that the vapour density of salts was determined by Nernst. 

In high resolution NMR experiments in relatively non-viscous liquids the observed chemical shifts relate to differences between values of the scalar a, for different nuclei, as defined by equations (6) and (8). 

It should be pointed out that the Semenov Theory was developed for gases, is generally applied to non-viscous liquids, but does not hold for solids. Solids will not show a uniform temperature distribution because of their poor thermal conductivity. For solids, a more complex model must be used, such as the Frank-Kamenetskii Theory. (6) Discussions of this theory and others can be found in the literature. (7)...
