Standard X-Ray Diffraction Powder Patterns
NBS MONOGRAPH 25 — SECTION 1 Standard X-ray Diffraction U.S. DEPARTMENT OF COMMERCE NATIONAL BUREAU OF STANDARDS THE NATIONAL BUREAU OF STANDARDS Functions and Activities The functions of the National Bureau of Standards are set forth in the Act of Congress, March 3, 1901, as amended by Congress in Public Law 619, 1950. These include the development and maintenance of the national standards of measurement and the provision of means and methods for making measurements consistent with these standards; the determination of physical constants and properties of materials; the development of methods and instruments for testing materials, devices, and structures; advisory services to government agencies on scien- tific and technical problems; invention and development of devices to serve special needs of the Government; and the development of standard practices, codes, and specifications. The work includes basic and applied research, development, engineering, instrumentation, testing, evaluation, calibration services, and various consultation and information services. Research projects are also performed for other government agencies when the work relates to and supplements the basic program of the Bureau or when the Bureau's unique competence is required. The scope of activities is suggested by the listing of divisions and sections on the inside of the back cover. Publications The results of the Bureau's research are published either in the Bureau's own series of publications or in the journals of professional and scientific societies. The Bureau itself publishes three periodicals available from the Government Printing Office: The Journal of Research, published in four separate sections, presents complete scientific and technical papers; the Technical News Bulletin presents summary and preliminary reports on work in progress; and Basic Radio Propagation Predictions provides data for determining the best frequencies to use for radio communications throughout the world. -

THE STRUCTURE OF THE COLLODION MEMBRANE AND ITS ELECTRICAL BEHAVIOR II, THE ACTIVATED COLLODION MEMBRANE BY KARL SOLLNER, IRVING ABRAMS, AND CHARLES W. CARR (From the Department of Physiology, University of Minnesota, Minneapolis) (Received for pubfication, March 31, 1941) I In preceding communicationst, 2 we were led to the conclusion that the elec- trochemical activity of collodion membranes, as manifested by concentration potentials, etc., is due principally to acidic impurities. Accordingly, different brands of collodion differ widely as to their activity, the purer brands being less active. The impure (but active) foreign brands of collodion, heretofore generally used by workers in the field of electrochemical membrane investiga- tion, are no longer obtainable. In order to continue our investigation, it became necessary to find methods to produce active collodion membranes at will. The idea of inducing changes in the electrochemical characteristics of mem- branes is not entirely new. Many investigators have activated membranes by the adsorption of proteins, e.g. the proteinized membranes of Loeb. 8 Other investigators use other organic compounds, usually dyestuffs. These may be adsorbed like proteins or they may be dissolved in the collodion solution* pre- vious to casting the membranes. Such membranes are interesting and useful in their own right, but are not altogether satisfactory substitutes for active collodion membranes. They very often show considerable asymmetry; more- over, the dyestuffs so far employed (according to the literature) are slowly re- leased into the solution in contact with the membrane, whereby the character of the membrane is considerably changed. Meyer and Sievers5 used an oxida- tion method to activate a cellophane membrane. -

NACE Bromine Chemistry Review Paper
25 YEARS OF BROMINE CHEMISTRY IN INDUSTRIAL WATER SYSTEMS: A REVIEW Christopher J. Nalepa Albemarle Corporation P.O. Box 14799 Baton Rouge, LA 70898 ABSTRACT Bromine chemistry is used to great advantage in nature for fouling control by a number of sessile marine organisms such as sponges, seaweeds, and bryozoans. Such organisms produce small quantities of brominated organic compounds that effectively help keep their surfaces clean of problem bacteria, fungi, and algae. For over two decades, bromine chemistry has been used to similar advantage in the treatment of industrial water systems. The past several years in particular has seen the development of several diverse bromine product forms – one-drum stabilized bromine liquids, all-bromine hydantoin solids, and pumpable gels. The purpose of this paper is to review the development of bromine chemistry in industrial water treatment, discuss characteristics of the new product forms, and speculate on future developments. Keywords: Oxidizing biocide, bleach, bromine, bromine chemistry, sodium hypobromite, activated sodium bromide, Bromochlorodimethylhydantoin, Bromochloromethyethylhydantoin, Dibromodi- methylhydantoin,, BCDMH, BCMEH, DBDMH, stabilized bromine chloride, stabilized hypobromite INTRODUCTION Sessile marine organisms generate metabolites to ward off predators and deter attachment of potential micro- and macrofoulants. Sponges, algae, and bryozoans for example, produce a rich variety of bromine-containing compounds that exhibit antifoulant properties (Fig. 1).1,2,3 Scientists are actively studying these organisms to understand how they maintain surfaces that are relatively clean and slime- free.4 Brominated furanones isolated from the red algae Delisea pulchra, for example, have been found to interfere with the chemical signals (acylated homoserine lactones) that bacteria use to communicate with one another to produce biofilms.5,6 This work may eventually lead to more effective control of microorganisms in a number of industries such as industrial water treatment, oil and gas production, health care, etc. -
Used at Rocky Flats
. TASK 1 REPORT (Rl) IDENTIFICATION OF CHEMICALS AND RADIONUCLIDES USED AT ROCKY FLATS I PROJECT BACKGROUND ChemRisk is conducting a Rocky Flats Toxicologic Review and Dose Reconstruction study for The Colorado Department of Health. The two year study will be completed by the fall of 1992. The ChemRisk study is composed of twelve tasks that represent the first phase of an independent investigation of off-site health risks associated with the operation of the Rocky Flats nuclear weapons plant northwest of Denver. The first eight tasks address the collection of historic information on operations and releases and a detailed dose reconstruction analysis. Tasks 9 through 12 address the compilation of information and communication of the results of the study. Task 1 will involve the creation of an inventory of chemicals and radionuclides that have been present at Rocky Flats. Using this inventory, chemicals and radionuclides of concern will be selected under Task 2, based on such factors as the relative toxicity of the materials, quantities used, how the materials might have been released into the environment, and the likelihood for transport of the materials off-site. An historical activities profile of the plant will be constructed under Task 3. Tasks 4, 5, and 6 will address the identification of where in the facility activities took place, how much of the materials of concern were released to the environment, and where these materials went after the releases. Task 7 addresses historic land-use in the vicinity of the plant and the location of off-site populations potentially affected by releases from Rocky Flats. -
