The structure of the title organic-inorganic hybrid compound, {(C(2)H(7)N(4)O)(2)[BiCl(5)]}(n), consists of corrugated chains parallel to [100] of corner-joined [BiCl(6)] octa-hedra, separated by layers of organic 1-carbamoylguanidinum cations. The crystal cohesion is achieved by N-H⋯O and N-H⋯Cl hydrogen bonds, which link the organic and inorganic parts of the structure.

The title compound, C8H13N2O + H2PO4, is an ionic salt. The organic species is protonated at the N atom of the dimethylaminomethyl group. The dihydrogenphosphate moieties are connected into in®nite chains by way of OÐH O links. The H2PO4 ÿ group also makes an OÐH N hydrogen bond to the pyridine N atom of the organic species. The organic cations crosslink the phosphate chains into a three-dimens...

-A chemical mass balance receptor model based on organic compounds has been developed that relates source contributions to airborne fine particle mass concentrations. Source contributions to the concentrations of specific organic compounds are revealed as well. The model is applied to four air quality monitoring sites in southern California using atmospheric organic compound concentration data ...

Investigations of cellular processes initiated by volatile organic compounds (VOCs) are limited when modelling realistic long-term exposure scenarios at low concentrations. Exposure to indoor VOCs is associated with a range of adverse effects, but data on molecular changes at regulatory threshold limits are lacking. Activity analysis of VOC in vitro can be a valuable complement to inhalation to...

The Organic Compound Analysis system, or OrCA, has been developed to integrate artificial intelligence techniques in an effort to elucidate chemical relationships. The first of its two major design goals is to study the interaction and supplementation of disparate techniques in artificial intelligence; the second is to examine the ability of a computer to learn and manipulate the complex relati...

Single-bubble sonoluminescence (SBSL) in water has been studied in the presence of low concentrations of simple organic compounds. For a given concentration of aliphatic alcohol, the degree of quenching follows the order, ethanol< I -propanol< 1-butanol, Preliminary experiments with simple we& acids and bases indicate that SBSL quenching only occurs when the pH is adjusted such that the solutes...

We report a high-performance chemiresistive sensor for detection of volatile organic compound (VOC) vapors based on core-shell hybridized nanostructures of Fe3O4 magnetic nanoparticles (MNPs) and poly(3,4-ethylenedioxythiophene) (PEDOT)-conducting polymers. The MNPs were prepared using microwave-assisted synthesis in the presence of polymerized ionic liquids (PILs), which were used as a linker ...

This paper evaluates the feasibility of using shredded tires for removal of organic compounds from landfill leachate. From the batch sorption isotherm experiments, tire chips were found to have 1.4% to 5.6% of the sorption capacity of granular activated carbon on a volume basis. The sorption equilibrium occurred within 2 days for 0.6-, 1.3-, and 2.5-cm size tire chips. The capacity of tire chip...

Plant leaves emit a broad spectrum of organic compounds that typically play multiple roles in plant protection. Furthermore, most of these compounds actively participate in tropospheric chemistry. There has been rapid progress in understanding how the emission of volatiles is regulated, mostly focusing on the biochemical controls over compound production. However, physicochemical characteristic...

Volatile organic compounds (VOCs) are small molecules that exhibit high vapor pressure under ambient conditions and have low boiling points. Although VOCs contribute only a small proportion of the total metabolites produced by living organisms, they play an important role in chemical ecology specifically in the biological interactions between organisms and ecosystems. VOCs are also important in...
