Surface-enhanced Raman scattering ~SERS! spectroelectrochemical investigations have been carried out in real time on the electrodeposition of copper from sulfuric acid solutions. Sulfate spectra were observed during copper deposition, but not on a copper surface at the same potential in the absence of copper ions in solution. This indicated that sulfate adsorption is a transient process associa...

The structure of the preformed LC mesophase of water:transition metal salt ([M(H2O)6]X2):acid (HX):oligo(ethylene oxide) (or Pluronics):tetramethylorthosilicate (TMOS) mixture during hydrolysis and partial polymerization of the silica source is maintained upon further polymerization and condensation of the silica species in the solid state. The liquid mixture in early stage of the silica polyme...

Bacteriolyses of bacterial cell walls by zinc (II) ions on the basis of the results of halo antibacterial susceptibility tests were investigated for the nitrate and the sulfate solutions. From the results obtained by halo antibacterial tests of sulfate solutions against Staphylococcus epidermidis, the antibacterial order is Zn2+>Cu2+>Ag+>Al3+, in which Zn2+ ions indicate the highest antibacteri...

Minimal liquid discharge (MLD) in greenhouses minimizes the volume of discharged wastewater, thereby increasing effluent that may be reused. Sodium accumulation wastewater is often considered main bottleneck to achieving 100% reuse. Consequently, have begun adopting reverse osmosis (RO), most commonly used desalination technology for treatment. RO removes ions from indiscriminately, including m...

The title compound, [Tl(2)(C(3)H(10)NO(9)P(3))](n), a Tl(I) organic-inorganic hybrid complex, was synthesized by the reaction of nitrilo-tris(methyl-enephospho-nic acid) with thallium(I) nitrate. There are two types of Tl(+) ions in the complex, with coordination numbers of eight and seven and with stereochemically active and inactive lone-pair electrons, respectively. In the crystal, the doubl...

Introduction: Water is vital for life. Its inadequate quality causes significant effects on the health condition of the individuals and society. Groundwater is one of the sources of Nitrate that level over standard limits may lead to several health problems such as hemoglobin metabolism and the formation of nitro amino compounds. Therefore, the aim of this study is determining ...

It is challenging to integrate porous graphene foam (GF) and GF-based nanocomposites into microfluidic channels and even create microfluidic structures within these materials. This is because their irregular interior pore shape and geometry, rough exterior surface, and relatively large material thickness make it difficult to perform conventional photolithography and etching. This challenge has ...

In this work ternary CdZnS thin films were prepared by chemical bath deposition by doping CdS with different concentrations of Zn ions. The chemical bath comprised of cadmium nitrate [Cd(NO3)2], as a source of Cd 2+, zinc nitrate [ZnNO3)2]as source of Zn 2+ , thiourea [(NH2)2CS] as a source of sulphide ions [S 2]in the presence of ammonia [NH3] as a complexing agent. The competition mechanisms ...

In the title compound, Pb(2)(HPO(3))(NO(3))(2), the two distinct Pb(2+) ions (both with site symmetry m) adopt irregular PbO(10) coordination polyhedra. The structure is completed by two distinct nitrate groups (in which one O atom and the N atom have m site symmetry for both ions) and an HPO(3) (2-) anion (in which one O atom and the P and H atoms have m site symmetry). The connectivity of the...

Germfree and conventional-flora Sprague-Dawley rats were fed sodium nitrate or sodium nitrite in their drinking water (1,000 microgram/ml), and various organs, tissues, and sections of the intestinal tract were assayed for nitrate (NO3-) and nitrite (NO2-) by a spectrophotometric method. When fed NO3-, germfree rats had chemically detectable levels of NO3- (only) in the stomach, small intestine...
