A model is presented for a parallel plate electrochemical reactor which has electrodes that are the same size and are close together. That is, the distance between the electrodes (S) is much smaller than the length (L) or width (W) of the electrodes. Consideration of the material balance equations in light of this small aspect ratio (S/L) condit ion leads to predict ions of derived quanti t ies...

The presence of high levels of Cu in soil decreases the shoot and root dry weights of Eucalyptus globulus. However, higher plant tolerance of Cu has been observed in the presence of the arbuscular mycorrhizal (AM) fungus Glomus deserticola. The hyphal length of G. deserticola was sensitive to low Cu concentrations, and the percentage of AM root colonisation and the metabolic activity of the AM ...

Abstract The influence of CuO/ZrO 2 /ZnO (Cu/Zr/Zn) catalyst modification with Mn, Ni, Ga on the physicochemical properties and activity toward hydrogen production in steam reforming ethanol (SRE) reaction has been evaluated. increase yield lowest selectivity to acetaldehyde were observed upon Cu/Zr/Zn Mn Ga. characterisation spent catalysts revealed changes phase compositions reducibility. In ...

Um composto de fórmula [ttf] 2 [Cu(opba)]·H 2 O, com ttf = tetrathiafulvaleno e opba = orto-fenilenobis(oxamato), foi preparado e caracterizado. O complexo foi obtido por reação de metátese entre (ttf) 3 (BF 4 ) 2 e (Bu 4 N) 2 [Cu(opba)] em acetonitrila à temperatura ambiente. O espectro UV-Vis-NIR mostra a presença do radical cátion em duas formas, (ttf ) e dímero (ttf ) 2 . As propriedades de...

NW-tending faults in Central Iran are expected to represent dominant dextral components due to their orientation with respect to the northward motion of the Arabian Plate with respect to Eurasia. However, previously published works, as well as the focal mechanism solution of the area's earthquakes, indicate evidence of sinistral kinematic along the major faults in Central Iran. Here we present ...
