nickel doped tio2 nano particles (1% w/w) were prepared and immobilized on nax zeolite and after characterization by x-ray diffraction (xrd) and scanning electron microscopy (sem) used as photo catalyts for degradation of orange g. the xrd patterns show that the supported tio2 are crystallized in anatase form and the intensity of the zeolite peaks decreases with the increase of tio2 loading. sc...

TiNi alloys are known as good biomaterials for medical applications since they exhibit compatibility with body tissue [1]. However, the possible release of Ni atoms to the body is a typical side effect where it can cause hazards to the operating system. The general interest here is thus to avoid the adverse effect by minimizing the existence of Ni atoms at the biomaterial surface layer. We have...

The oxidation rate of sputtered tungsten-based coatings, oxidised in air at temperatures of 6008C±8008C can be in ̄uenced signi®cantly by the addition of small amounts of nickel, titanium and carbon. The presence of carbon does not change the type of oxide phases formed during the oxidation of sputtered W coatings: there are two oxide layers, the inner being a compact sub-oxide of WOx type and t...

Biferrocene bearing planar metal dithiocarbamates, namely, [M(FcCH2dtc)2] (dtc = furan-2-ylmethyldithiocarbamate, M = Cu(II) 1, Ni(II) 4; dtc = benzo[d][1,3]dioxol-5-ylmethyl dithiocarbamate, M = Cu(II) 2, Ni(II) 5; dtc = pyridin-2-ylmethyldithiocarbamate, M = Cu(II) 3, Ni(II) 6; Fc = ferrocenyl; Fe(η(5)-C5H5)(η(5)-C5H4-)), have been synthesized and characterized by microanalysis, magnetic susc...

The photoexcited electron injection dynamics of free-base and metallo-derivatives of tris(pentafluorophenyl)porphyrins bound to TiO2 and SnO2 nanoparticle surfaces have been investigated using timeresolved terahertz spectroscopy (TRTS). The metallo-derivatives include Zn(II), Cu(II), Ni(II), and Pd(II). For the TiO2−porphyrin assemblies, electron injection from the photoexcited dye to the semic...

The energy density of current lithium-ion batteries (LIBs) based on layered LiMO2 cathodes (M = Ni, Mn, Co: NMC; M = Ni, Co, Al: NCA) needs to be improved significantly in order to compete with internal combustion engines and allow for widespread implementation of electric vehicles (EVs). In this report, we show that atomic layer deposition (ALD) of titania (TiO2) and alumina (Al2O3) on Ni-rich...
