Intensify manufacturing processes, so that compact chemical plants can make required amounts of product efficiently, safely, and with minimal environmental impact. 

A good understanding of the detailed chemistry of oxidant formation makes it possible to construct more compact chemical models. These generalized or lumped mechanism models reduce the number of individual chemical reactions by combining similar or sequential reactions and ig-... 

Group 2 includes 59 samples that cluster together. The group is not as compact chemically as Group 1, though still consistently compact. Eighteen elements vary under 10%, ten under 20% and only two over 20%. The Ca values are quite similar to Group 1 (5.88% with 41% spread), the A1 and Fe (as most... 

This short index to the tryptamines lists the fifty-five chemical entries by their code names followed by a compact chemical name. All numbers, letters and atom symbols are ignored in the alphabetization. The abbreviation T is for tryptamine, C is for f -carboline, L is for ly sergamide and NL is for 6-norly sergamide. The long index includes all synonyms and is to be found in Appendix F. 

Another way to stabilize the HTSC surface state is to passivate it by the formation of thin, compact, chemically inactive films. Chemical methods of passivation in solution [521] generally consist in the formation of poorly soluble salts (sulfides, iodides, oxalates, etc.) of the metal components. The oxidation of the thin surface layers accepted for the passivation of semiconductors [220,221] apparently cannot be directly applied for oxide materials, and requires further development. The insoluble compounds that form on HTSC surfaces do not display pronounced passivating properties. 

Compact chemical sensors can be broadly classified as being based on electronic or optical readout mechanisms [28]. The electronic sensor types would include resistive, capacitive, surface acoustic wave (SAW), electrochemical, and mass (e.g., quartz crystal microbalance (QCM) and microelectromechanical systems (MEMSs)). Chemical specificity of most sensors relies critically on the materials designed either as part of the sensor readout itself (e.g., semiconducting metal oxides, nanoparticle films, or polymers in resistive sensors) or on a chemically sensitive coating (e.g., polymers used in MEMS, QCM, and SAW sensors). This review will focus on the mechanism of sensing in conductivity based chemical sensors that contain a semiconducting thin film of a phthalocyanine or metal phthalocyanine sensing layer.

Table 7.1 shows a number of excellent binders developed to date. Binders properties include - besides the actual binding - flexibility when used for electrodes, insolubility in the electrolyte, compactness, chemical and electrochemical stability, and easy application to electrode paints. The binder should be able to satisfy all of these properties simultaneously. This is a difficult task, and only two binders that comply with all these requisites have been found polyvinylidene fluoride (PVDF) and styrene-butadiene copolymer (SBR). 

In the case of solids, segregation is advisable from the point of view of selecting suitable process for volume reduction e.g. incineration, compaction, chemical oxidation or direct disposal.
