Metal conductive ink for flexible electroncs has exhibited a promising future recently. Here, an innovative strategy was reported to synthesize silver nanocolloid (2.5±0.5 nm) and separate solid silver nanoparticles (<10 nm) effectively. Specifically, silver nitrate (AgNO3) was used as a silver precursor, sodium borohydride (NaBH4) as a reducing agent, fatty acid (CnH2n+1COOH) as a dispersant a...

This paper deals with the results of quantum chemical modeling monoacyl-sn-glycerol 2D cluster formation at air/water interface using a semi-empirical PM3 method. The impact 2 or 3 positions acyl substituent on thermodynamics monolayer is assessed for surfactants an CnH2n+1COO chain length n = 6–17 carbon atoms. calculation shows significant change in spontaneous clusterization threshold isomer...

OBJECTIVE In this study, a pilot-scale investigation was conducted to examine and compare the biotoxicity of the organic compounds in effluents from five treatment processes (P1-P5) where each process was combination of preoxidation (O3), coagulation, sedimentation, sand filtration, ozonation, granular activated carbon, biological activated carbon and chlorination (NaClO). METHODS Organic com...

Six new organic-inorganic hybrid compounds based on [XM12O40](4-) (X = heteroatom, M = metal atom), namely [Cu(pic)2][H2XM12O40]·2Hapy·2apy (X = Si, M = W for , X = Ge, M = W for and X = Si, M = Mo for ), [Cu(2,2'-bpy)2][Cu(2,2'-bpy)(H2O)][Cu(pic)2]0.5[XM12O40]·nH2O (X = Si, M = Mo, n = 0.5 for , X = Ge, M = W, n = 1 for ) and [Cu(phen)(H2O)]2[Cu(pic)2][GeW12O40]·2.5H2O () (pic = deprotonated p...

Adsorption using activated carbon and ion-exchange is used to remove a range of organic compounds and ammonia respectively from treated wastewaters. Such treatment may follow secondary biological treatment to reduce BOD. Organic nitrogen (e.g. proteins) is degraded to ammonia and residual organic compounds may also be present following secondary treatment. Residual organic compounds may be thos...

A dye-sensitized metal-organic framework, TMU-5S, was synthesized based on introducing the laser dye Rhodamine B into the porous framework TMU-5. TMU-5S was investigated as a ratiometric fluorescent sensor for the detection of explosive nitro aromatic compounds and showed four times greater selectivity to picric acid than any state-of-the-art luminescent-based sensor. Moreover, it can selective...
