Focus of This Report

Since the identification of hydroxamic acids as potent bidentate ZBGs, an enormous range of hydroxamic acid inhibitors based on this model has been developed and is described in numerous reviews and therefore will not be dealt with in depth here [17]. Instead, the focus of this report will be on efforts to improve on these "1st generation" inhibitors, specifically to improve biological and physicochemical characteristics, such as pharmacokinetics and bioavailability and to achieve isoform selectivity. 

In this contribution, we have made an attempt to summarize several aspects of radical ions. Although ESR studies are in the focus of this report, we have also included investigations with other spectroscopic methods and chemical characteristics to illustrate the scope of these reactive species. 

Even allowing for employees who work at multiple disposal sites over the duration of the CSDP, Table 1-1 shows that a substantial number of people will be involved in the destruction of the stockpile. The focus of this report is on workplace chemical monitoring and worker activity and health monitoring practices at CAMDS, JACADS, TOCDF, and, by extension, at the other seven disposal facilities planned or under construction. The preparation, maintenance, and accessibility of records are also evaluated. Findings on current practices and recommendations for extending and/or improving them are then presented. 

Biological strategies to remove C02 from the atmosphere, although not the focus of this report, deserve mention. These strategies remove carbon from the atmosphere by photosynthesis. On land, storage usually takes place at the same site as that of capture—for example, in a tree. Increases in atmospheric C02 enhance plant growth up to a point that is yet to be fully understood. In the ocean, capture is via various organisms at the surface that then sink into the deep ocean. 

Heterocyclic betaines and other unusual structures have been the subject of extensive investigation [88AHC(44)269 92AHC32]. The specific focus of this report is to survey recent progress in the chemistry of heterocyclic betaines and molecules with a betaine character of general type 1 (Scheme 1), and should serve to complement other reviews that deal with heterocyclic betaines of alternant hydrocarbons [80AHC(26)1] and heterocyclic mesomeric betaines (85T2239). 

Currently in our laboratories we are exploring the role of anion structure and packing as well as intrastructural metal ion composition of these potential components of fire retardant formulations, as well as investigating LDHs for this purpose. The focus of this report is on evaluation of the effects of a zinc/copper HDS on thermal stability and flammability of low density poly(ethylene). 

Details of the Pitzer equations and definitions of the notations utilized in this paper and in PHRQPITZ are given in the literature (3-lOL As the focus of this report is on the capabilities and limitations of PHRQPITZ in relation to its application to geochemical problems, only selected aspects of the implementation of the Pitzer equations in PHRQPITZ are presented. 

Although the focus of this report is the analysis of physiologically relevant lipid mixtures, some comments on typical patterns of MALDI-TOF mass spectra of lipids will be given on the hand of defined lipids. 

While the focus of this report is on the liquid waste streams from the EDS, the committee notes that it is not always possible to separate the regulatory approval and permitting (RAP) process for EDS liquid waste destruction technologies from the regulatory approval process for the EDS system as a whole. RAP issues for the oveaall EDS system are to be explored in greater detail in a subsequent report. 

The destruction of sarin (GB) in the EDS using aqueous MEA (45 percent) as the treatment chemical produces an organic-rich neutralent stream, as described in Chapter 2. The postireatment of this neutralent stream is the focus of this report, but there are also other liquid waste streams that must be dealt with. The other streams result from the riusing of the EDS chamber with water after each use to remove residual MEA and soUd residues and the cleaning to remove other solid and liquid residues. These waste streams must also be prepared for ultimate disposal unless their compositions meet the feed requirements for an on-site treatment works. The diverse nature of these waste streams is illustrated in Table C-1. 

The growing security threat of COCs thus presents a new challenge to working with chemicals in the laboratory, especially in small-scale industrial and academic settings. While large-scale industrial manufacturing and use of COCs is a dominant concern in national and international chemical security, use of chemicals at the laboratory scale poses a unique and significant security threat and is the main focus of this report.

The description of PDAs as wide bandwidth systems provides an efficacious perspective for our present itinerary through their optical and electronic properties, particularly by at least superficial analogy to well known inorganic solids. Not surprisingly, seminal reports of large carrier mobilities (5) and nonlinear optical coefficients (6) have appeared and have generated substantial interest in their verification and elaboration. Our collective efforts in these directions will be the major focus of this report. 

The focus of this report is to investigate and improve the synthesis of bis-(3-trimethoxysilylpropyl)fiimarate and develop a method to synthesize the bis-(3-trimethoxysilylpropyl)maleate isomer. This paper also outlines some of the analytical methods used to characterize and quantify the intermediates and isomers obtained during the synthesis. 

The work described here is part of a continuing project aimed at investigating the formation of non-volatile compounds, both colorless and colored, in Maillard model systems (P, 10). The focus of this report is the effect of time of heating and subsequent storage on the profile of reaction products formed from an aqueous xylose-lysine hydrochloride model system. 

The focus of this report concerns nanocomposites from poly(propylene carbonate) (PPG) and multiwall carbon nanotubes (MWNTs). A solvent route using THF, ethoxylated non- ionic surfactants combined with sonication was found to be successful in deagglomerating and dispersing the nanotubes. The morphology and molecular mobility of the prepared nanocomposites (0.5, 3.0 and 5.0 wt% of nanotubes) were characterized by rheology, microscopy, low-field SS NMR, and electrical conductivity. The networking of nanotubes was highest with a steatyl alcohol ethoxylate surfactant, and was found to improve with the sonication...
