Pilot Studies. Applications requiring the reduction of VOC emissions have increased dramatically. On-site pilot tests are beneficial in providing useful information regarding VOC emission reduction applications. Information that can be obtained includes optimum catalyst operating conditions, the presence of contaminants in the gas stream, and the effects of these contaminants (see Pilotplants and microplants). 

The concept of this process has been demonstrated for lowering or increasing the alcohol content of distilled spirits by using water vapor or ethanol vapor in the sweep stream, respectively. In either case, this vapor arbitration action combined with the inherent selectivity of the membrane resulted in virtually complete preservation of the subtle character of the beverage, but in a more concentrated form due to the lower net volume of the retentate product (Lee, 1993). Similar results may be anticipated in other volume reduction applications involving high-value volatile feedstocks. 

Microwave-absorbing materials are currently in high demand for many expanded EMI shielding and radar cross section reduction applications with both commercial and defense purposes. The nanostructured materials have attraction for microwave radiation absorbing and shielding materials in the high-frequency range due... 

A data matrix produced by compositional analysis commonly contains 10 or more metric variables (elemental concentrations) determined for an even greater number of observations. The bridge between this multidimensional data matrix and the desired archaeological interpretation is multivariate analysis. The purposes of multivariate analysis are data exploration, hypothesis generation, hypothesis testing, and data reduction. Application of multivariate techniques to data for these purposes entails an assumption that some form of structure exists within the data matrix. The notion of structure is therefore fundamental to compositional investigations. 

Electrochemical detectors can be used in the oxidative mode for a wide range of drugs, including cannabinoids, haloperidol, morphine, paracetamol, phenothiazines, salicylic acid, and tricyclic antidepressants. Operation in the reductive mode is more difficult as dissolved oxygen must be removed from the eluent (K. Bratin et al, J. liq. Chromat., 1981,, 1777-1795). Reductive applications include chloramphenicol and benzodiazepines. 

The dynamic mechanical properties are of direct relevance to a range of unique polymer applications concerned with the isolation of vibrations or dissipation of vibrational energy in engineering components (e.g. noise reduction). Applications concerned with creep and stress relaxation under static loading conditions in engineering components can be approximately estimated from the dynamic mechanical properties determined over wide ranges of frequency and temperature. 

Diborane is not stable at room temperature and is usually generated in situ. It is available from Alfa Inorganics but only in a very dilute solution in THF. Adams et al. report that dimethyl sulfide -borane provides a useful substitute for diborane. It is less reactive than diborane, but can be used for most hydroboration and reduction applications.

The most common chemicals used for chromium reduction and other chemical reduction applications are sulfur dioxide (SO2), sodium metabisulfite (Na2S205), sodium bisulfite (NaHSOg), and sulfuric acid (H2SO4).

The third entry in Table I is "The monotonic recovery , implying that the interest in supercritical fluid extraction is again increasing. Although the less than lustrous performance of supercritical fluids in energy reduction applications delayed or reduced other process development activity, currently there is increasing activity in supercritical fluid extraction. The resurgent interest resides in a n imber of factors, e.g.. 

Dynamic topologies. Polymer aggregates seem most promising for drag reduction applications because both the shear stability, and the performance are improved through supramolecular associations. However, many fundamental questions remain unanswered. How does the strength of the secondary bonds... 

Membrane Distillation (MD) is a hybrid thermal-membrane process that could be applied in produced water volume reduction applications while simultaneously augmenting sustainable water production in Qatar. A consortium of ConocoPhillips - Global Water Sustainability Center (GWSC), Qatar University (QU) and Qatar Electricity Water Company (QEWC), was formed to assess the suitability of MD to treat high salinity brines from thermal desalination plants similar salinity levels could be found in produced water. The pilot scale results showed that MD could operate at 50% recovery and achieve a stable flux of 5 L/(m. h) at when treating thermal brine at 70,000 mg/L TDS. The effluent produced contained < 10 mg/L TDS.
