For pure metals aluminum and magnesium for chemical compounds Al3Mg, Al2Mg, AlMg AlMg3 with crystallographic orientations (100), (110) (111) the work function is calculated from first principles in framework of density functional theory. It shown that dependence on concentration aluminium nonlinear. The reasons differences depending orientation are analysed.

Novel nanostructured materials, such as aluminum oxide (AlOOH), silicon oxide (SiO2) or zirconium oxide (ZrO2) embedded into PVA, were investigated as potential matrices to incorporate organometallic compounds (OMCs) for the development of optical oxygen-sensitive sensors which make use of the principle of luminescence quenching.

Fire blight (FB), caused by Erwinia amylovora, is one of the most important pome fruit pathogens worldwide. To control this devastating disease, various chemical and biological treatments are commonly applied in Switzerland, but they fail to keep the infection at an acceptable level in years of heavy disease pressure. The Swiss authorities therefore currently allow the controlled use of the ant...

Some 2-hydroxy-4-methyl-6substituted quinoline derivatives have been synthesized in an environmentally benign method from easily available 4-substituted anilines and β-Ketoesters, under ordinary conditions. The reactions were catalyzed by aluminium chloride to afford excellent amount of the products. The usage of hazardous acids, bases and solvents have been avoided in different steps of the re...

Chloroaminocyclotriphosphazatrienes, N3P3Cl6-nRn [R = NHMe (n = 2), NHEt ( n = 1, 2), NHPr« (n = 4), NHPr* ( n = 1, 4), NHBu< (n = 2, 4), NHCH2Ph ( n = 1), NEt2 (n= 1, 2, 3), N(CH2Ph)2 (n = 1)] react with benzene in the presence of anhydrous aluminium chloride to give phenylated products: phosphazenes and/or hydrocarbons. The structures of the phenylphosphazenes are assigned from their NMR spec...

Multi-stage deposition of metals from a sulfate solution with high concentration iron, aluminum, copper, zinc, and nickel has been studied. The concentrations the components correspond to composition sub-basement waters Gaisky GOK. Granular magnesia-silicate reagent based on serpentinite (Khalilovsk magnesite deposit, Orenburg region, Russia) used as an alkaline agent. reagent's ability reduce ...
