Herein a novel inorganic-organic hybrid Keggin-type heteropolymolybdate [Ni2Na(C12H8N2)4(BMo12O40)(H2O)2] (1) has been synthesized under hydrothermal conditions in aqueous solution. The cyrstal structure was fully characterized by powder X-ray diffraction (XRD), elemental analysis, Fourier-tranform infrared spectrum (FT-IR), Thermogravimetric analysis (TGA) and Scanning Electron Microscopy (SEM...

the gas separation performance of commercial ceramic titania and hybrid silica (hybsi®) membranes was assessed using the gas permeation and permporometry methods. results indicated that the hybsi® membranes have a hybrid surface containing regions covered by a polymeric matrix and others with inorganic pores. these membranes have high h2 selectivity, which increases significantly with temperatu...

Three new inorganic-organic hybrid compounds based on Strandberg-type anions and Zn(ii)-H2biim/H2O subunits, namely {H4(H2biim)3}[Zn(H2biim)(H3biim)(H2O)(HP2Mo5O23)]2·3H2O (1), {H9(H2biim)7}[(μ-biim){(Zn(H2O)2)0.5(HP2Mo5O23)}2]·7H2O (2) and {H7(H2biim)7}[Zn(H2biim)(H2O)2(HP2Mo5O23)][H2P2Mo5O23]·8H2O (3) (H2biim = 2,2'-biimidazole), have been synthesized in aqueous solutions and characterized. T...

Knowledge of the physical state and morphology of internally mixed organic/inorganic aerosol particles is still largely uncertain. To obtain more detailed information on liquid-liquid phase separation (LLPS) and morphology of the particles, we investigated complex mixtures of atmospherically relevant dicarboxylic acids containing 5, 6, and 7 carbon atoms (C5, C6 and C7) having oxygen-to-carbon ...

the aim of this study was to investigate the comparison between some seminal plasma parameters and age of the bull. concentrations of various biochemical parameters like fructose, glucose, total proteins, albumin and inorganic ions including na, k and cl ions of seminal plasma of breeding sahiwal bulls of different ageswere assessed. methods: 40sahiwal bullsdivided into 4 age groups.semen (2ml ...

achillea tenuifolia lam. (asteraceae) afforded a dichloromethane fraction from which three known compounds β-sitosterol (compound1), 5-hydroxy, 4',6,7– trimethoxy flavone (salvigenin compound 2), and methyl-gallate (compound 3) were isolated for the first time. the structure of isolated compounds was elucidated by different spectroscopic methods. applying the molar-ratio method, the comple...

In this study, ion exchange nanocomposite membranes was prepared by addition of Mg(OH)2 nanoparticles to a blend containing sulfonated polyphenylene oxide and sulfonated polyvinylchloride via a simple casting method. Magnesium hydroxide nanoparticles were synthesized via a facile sono-chemical reaction and were selected as filler additive in fabrication of ion exchange nanocomposite membranes. ...

adsorption is a fundamental process in the physicochemical treatment of wastewaters which industries employ to reduce hazardous organic and inorganic wastes in effluents. in recent years the use of low-cost adsorbents has been widely investigated as a replacement for the currently costly methods of removing heavy metal ions from wastewater. it is well-known that cellulosic waste materials can b...

Three barrel-shaped artificial molecular capsules 1-3, based on normal cucurbit[5]uril (Q[5]) and decamethylcucurbit[5]uril (Me10Q[5]), were synthesized and structurally characterized by single-crystal X-ray diffraction. Encapsulation of a chlorine anion in the cavity of a Q[5] or Me10Q[5] to form closed a molecular capsule with the coordinated metal ions or coordinated metal ions and water mol...
