Herein, density functional theory was used to investigate Gas sensor the (12,0) boron nitride nanotube (BNNT) and Si–doped BNNT as possible candidates to sarin detection. The Si- Boron nitride nanotube atoms doped improve the electronic properties of nanotubes by altering the electrostatic potential, HOMO and DFT LUMO energies. Based in the adsorption energies and the conductivity increased to ~33 and 350%, respectively, for Si- and 2Si-BNNT imply that they can be used for sarin detection.

    Industry Compliance Programme

    Global Chemical Industry Compliance Programme GC-ICP Chemical Weapons Convention December 2006 Version 1.0 GLOBAL CHEMICAL INDUSTRY COMPLIANCE PROGRAMME FOR IMPLEMENTING THE CHEMICAL WEAPONS CONVENTION The purpose of the handbook is to provide guidance to chemical facilities, traders and trading companies in developing a Global Chemical Industry Compliance Programme (GC-ICP) to comply with the Chemical Weapons Convention (CWC). The GC-ICP focuses first on determining if there is a reporting requirement to your National Authority and second on collecting the relevant support data used to complete the required reports. The GC-ICP is designed to provide a methodology to comply with the CWC and establish systems that facilitate and demonstrate such compliance. Each facility/company should also ensure that it follows its country’s CWC specific laws, regulations and reporting requirements. • Sections 2, 3, and 4 guide you through the process of determining if chemicals at your facility/ company should be reported to your National Authority for compliance with the CWC. • Section 5 provides recommended guidance on information that you may use to determine your reporting requirements under the CWC and administrative tools that your facility/company may use to ensure compliance with the CWC. • Section 6 provides a glossary of terms and associated acronyms. • Section 7 provides a listing of all National Authorities by country.

    Spectrophotometric Determination of Thiocyanate In

    Investigative Forensic Sciences © All rights are reserved by Buddha D. Paul and Thomas Research Article Open Access Spectrophotometric Determination of Thiocyanate in Human Saliva by a Unique Iodine-Azide-Chromogenic Substrate Reaction and its Application in Distinguishing Tobacco Smokers from Non-Smokers† Buddha D. Paul and Thomas Bosy Division of Forensic Toxicology, Office of the Armed Forces Medical Examiner, Dover AFB, Delaware, USA. Abstract A method to detect thiocyanate (SCN) in human saliva is presented. Thiocyanate concentrations appear to be diagnostic when classifying smokers or non-smokers, and in determining some clinical conditions. The method involves the reaction of SCN with excess iodine and azide, and spectroscopic detection of unreacted iodine by a chromogenic substrate, ABTS. The calibration was linear over the range of 12.5-150 µmol/L (slope = 0.0086 delta-Abs/SCN µmol/L, intercept = -0.0160 delta-Abs, R2 0.9998). The method was applied to analyze 29 saliva specimens. The results were similar to those obtained from a gas chromatography-mass 2 spectrometry method (slope = 0.9595, R 0.9790). Based on Grubbs equation applied to specimens from non-smoking subjects, a threshold concentration of 1100 µmol/L for SCN was determined to distinguish smokers from the non-smokers. The SCN concentrations in 18 out of 20 saliva specimens collected from 2 smokers were above this threshold. The specimens from smokers were also examined for nicotine and cotinine by a GCMS method. While nicotine concentrations were found to vary, the cotinine concentrations remained stable, 134+29 ng/mL. Generally, the presence of nicotine/cotinine in specimens only indicates exposure to tobacco products, but the presence of any of these compounds with elevated SCN, is an indication of smoking.

    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.
