Separating carbon dioxide from its polluting source may soon be cleaner and more efficient, research at a California lab indicates. A Lawrence Livermore National Laboratory researcher developed a screening method that would use ionic liquids -- a type of molten salt that liquefies under the boiling point of water -- to separate carbon dioxide from its source, the Livermore, Calif., lab said Wednesday in a release. The method is cleaner, more viable and more stable than what is available now,...

COEUR D'ALENE, Idaho, June 23 /PRNewswire-FirstCall/ -- Metalline Mining Company (Amex: MMG) is pleased to announce very positive initial cyanide leach results from the silver mineralization at Sierra Mojada, Coahuila, Mexico. Twenty three composite samples representing one hundred twenty four sample intervals from drill core into the deposit area were selected for triplicate head grade analyses prior to cyanide leach analyses at a commercial laboratory. These samples were selected to test...

By Phillips, Vaughan T J DeMott, Paul J; Andronache, Constantin ABSTRACT A novel, flexible framework is proposed for parameterizing the heterogeneous nucleation of ice within clouds. It has empirically derived dependencies on the chemistry and surface area of multiple species of ice nucleus (IN) aerosols. Effects from variability in mean size, spectral width, and mass loading of aerosols are represented via their influences on surface area. The parameterization is intended for application...

Certain explosives may soon get a little greener and a little more precise. LLNL researchers added unique green solvents (ionic liquids) to an explosive called TATB (1,3,5-triamino-2,4,6-trinitrobenzene) and improved the crystal quality and chemical purity of the material. This work, supported under the Transformational Materials Initiative (TMI) Laboratory Research and Development project, appears on the cover of the Sept. 1 issue of the journal Physical Chemistry Chemical Physics....

U.S. government scientists say they've developed a "green" method that makes some explosives safer and more stable. The Lawrence Livermore National Laboratory researchers say they added unique green solvents -- ionic liquids -- to an explosive called TATB and improved its crystal quality and chemical purity. "Improving crystal quality and purity leads to explosive materials that are (less likely to react violently) when subjected to mechanical impact or heat," said Larry Fried, the...

By Knee, Kelly M Dixit, Surjit B; Aitken, Colin Echeverria; Ponomarev, Sergei; Beveridge, D L; Mukerji, Ishita ABSTRACT The A-to-B form transition has been examined in three DNA duplexes, d(CGCGAATTCGCG)^sub 2^, d(CGCGAATTGCGC), and d(CGCAAATTTCGC), using circular dichroism spectroscopy, ultraviolet resonance Raman (UVRR) spectroscopy, and molecular dynamics (MD) simulation. Circular dichroism spectra confirm that these molecules adopt the A form under conditions of reduced water activity....

By Smith, S Takacs, I; Murthy, S; Daigger, G T; Szabo, A ABSTRACT: A phosphate complexation model is developed, in an attempt to understand the mechanistic basis of chemically mediated phosphate removal. The model presented here is based on geochemical reaction modeling techniques and uses known surface reactions possible on hydrous ferric oxide (HFO). The types of surface reactions and their reaction stoichiometry and binding energies (logK values) are taken from literature models of...

By Fine, Philip M Sioutas, Constantinos; Solomon, Paul A ABSTRACT Secondary aerosols comprise a major fraction of fine particulate matter (PM^sub 2.5^) in all parts of the country, during all seasons, and times of day. The most abundant secondary species include sulfate, nitrate, ammonium, and secondary organic aerosols (SOAs). The relative abundance of each species varies in space and time as a function of meteorology, source emissions strength and type, thermodynamics, and atmospheric...

By Abdel-Wahab, Ahmed Batchelor, Bill ABSTRACT: Interactions among chloride, sulfate, and silica removals from recycled industrial wastewater using an ultra-high lime with aluminum process (UHLA) were studied. An equilibrium model that is able to accurately predict the chemical behavior and interactions between chloride and sulfate or silica with UHLA at various initial conditions and chemical reagents was developed. X- ray diffraction (XRD) analysis was conducted to identify the...
