Current Chemical Papers

The literature cited in this article covers references listed in chemical abstracts to the end of 1961 and in current chemical papers after that. A degree of selection has been exercised in omitting some references that are now of limited value. Although metal nitrosyls are included in the scope of this chapter, no kinetic data on their decomposition is available and they will not be considered further. The data on metal carbonyls is limited and will be dealt with in the first section. The decomposition of metal alkyls and aryls has been extensively investigated. These compounds will be discussed in groups based on the position of the central metal atom in the periodic table and, when warranted, a further subdivision will be made based on the attached organic radicals. 

As long as a year can elapse between the time a paper appears and the time an abstract is published. Three publications help fill the gap by providing much the same information a list of the titles, authors, and keywords that appear in titles of papers recently published—or, in some cases, papers about to be published. These publications are Chemical Titles, Current Chemical Papers, and Current Contents. 

One of the earliest of these was Current Chemical Papers (Fig. 10) published monthly since 1954, which is a classified...

The publications of the Society include the Proceedings, the Journal , Current Chemical Papers, the Quarterly Reviews , and the Armual Reports on the Progress of Chemistry. 

The literature coverage is as complete as possible up to the end of 1962. Publications such as Current Chemical Papers and Chemical Abstracts have been scanned for references up to the middle of 1963. One finds but few spectra of tt complexes in commercial spectra catalogs and practically no mention of them in reviews, such as those of Bellamy 20) or Lecomte 21). However, a short survey of the infrared spectra of cyclo-pentadienylmetal complexes appeared in 1960 22). 

Chemical Physics Preprint Database. This database [81] is a fully automated electronic archive and distribution server intended to provide a means for rapid and efficient preprint distribution within the international theoretical chemical physics community. A preprint is a copy of a paper that has been submitted for publication. This database has been designed to be a useful and freely available tool for education and research. It allows investigators to submit and retrieve electronic copies of preprints via the Internet. Access for retrieval and listing of papers in the database is possible through WWW servers, anonymous ftp, or e-mail. Currently research papers are submitted to the databases via e-mail. This project is a joint effort by the Department of Chemistry at Brown University and the Theoretical Chemistry and Molecular Physics Group at the Los Alamos National Laboratory. The homepage of Chemical Physics Preprint Database is http // www.chem.brown.edu/chem-ph.html. (For a more... 

Anderson, E. L. "Risk Assessment and Application to Carcinogen Policy Development and Current Approaches," paper presented to the 184th National Meeting of the American Chemical Society, Kansas City, MO, 1982. 

He has been the president of Slovak (from 2007, member 1984) and member of Czech (2001) Chemical Societies. He has been a member on the editorial board of electronic journal ARKIVOC (1999) and Molecules (1999), European Journal of Organic Chemistry (2001), Current Organic Chemistry (2004), Tetrahedron (2004), Journal of Heterocyclic Chemistry (2006), Israel Science Foundation (2006), Acta Chimica Slovenika (2007), Chemical Papers, Collection of Czechoslovak Chemical Communications, VEGA, and GACR. He has to his credit over 90 publications, 30 lectures, 15 patent applications, about 160 citations in foreign scientific sources, co-authorship of 1 scriptum, 12 reviews and monographs, and 3 audiovisual courses. 

Structural Complexity. - Several papers reporting studies on the complexity of Platonic solids, Archimedean solids, fullerenes and nanotubes have appeared in the last couple of years. These are attractive structures and are of current chemical interest. 

Pulp and paper industrial equipment design consists of proper material seleetion in conjunction with the process chemicals and prevention of stagnant fluids in the process equipment. In the absence of corrosion, low-alloy carbon steel would be the material of choice if corrosion were not a problem. However, for many processes, stainless steel and even nickel-base and titanium alloys are required for better performance in corrosive environments. At present, current US paper mills are constructed of about one-third carbon steel and two-thirds stainless steels. There are several grades in the group of stainless steels. The relative cost of the stainless steels is dependent on the concentration of the major alloying elements (Cr, Ni, Mo), the volume produced, and the form in which it is supplied such as tube, pipe, plate, or block. It is useful to note that stainless steels are 10-20% more expensive than low-alloy carbon steels. 

It has been reported that a novel method for retrieving reactions similar to a given query reaction is to use relationships created by literature citations. Later publications citing a new reaction are likely to contain pertinent information about related reactions. In this study of all citing papers to 50 new s3oithetic methods indexed in Current Chemical Reactions, approximately half of the papers found by cited reference searching would not have been retrieved with reaction or substructure search approaches. 

A random sample of 50 reactions was selected from the June/July 1986 issues of Current Chemical Reactions (CCR). These reactions were pubhshed in the primary literature during the first quarter of 1986. This group of 50 reactions served as the core group for identif3dng the citing papers. 

In the USA, CHP accounts for approximately 7% of the total generation capacity [12]. The industrial market (most importantly chemicals, paper, refining, food and metal) accounts for 90% of the current CHP installations, the commercial market for the other 10%. The CHP potential in the USA is large 88 GW for industrial cogeneration and 75 GW for commercial cogeneration. If only a 2-3% of this potential is realised per year, it means a yearly CHP potential of 3.3-4.8 GW. 

Short-chain alkylated biphenyls are the principal biphenyl derivatives in commercial use. They are generally produced by Hquid-phase Friedel-Crafts alkylation of biphenyl with ethylene, propylene, or mixed butenes. A series of mixed ethylated biphenyl heat-transfer fluids (trademarked Therm S-600, 700, 800) is marketed by Nippon Steel. A mixed diethylbenzene—ethylbiphenyl heat-transfer fluid is also available from Dow (63). Monoisopropylbiphenyl [25640-78-2] largely as a mixture of meta- and para-isomers is produced by Koch Chemical Co. Monoisopropylbiphenyl (MIPB) was selected by Westinghouse (64,65) as a PCB replacement in capacitors and this is its primary appHcation today. For a time MIPB was also employed as a PCB replacement in pressure sensitive copy paper, but this outlet has since given way to other dye solvents. A similar product consisting of a mixture of j -butylbiphenyl isomers [38784-93-9] (66) is currently the favored dye solvent for pressure sensitive copy paper (67) manufactured in the United States.
