in this work, for the first time, the rheological properties of nanofluids of lanthania nanoparticles (nps) in ethylene glycol (eg) as functions of shear rate, volume fraction, and temperature were measured. the results showed that both eg and the nanofluids behave as non-newtonian fluids at lower shear rates and transform to newtonian fluids at higher shear rates. the values of viscosity for b...
Ordered binary oxide films of vanadium oxide have been prepared on an aluminum oxide film supported on Mo~110! under ultrahigh vacuum conditions and characterized by various surface analytical techniques. Auger electron spectroscopy, low energy electron diffraction, high-resolution electron loss spectroscopy, x-ray photoelectron spectroscopy and ion scattering spectroscopy indicate that the van...
Electron spectroscopy can now be applied to solids, liquids and gases. Some fields of research require ultrahigh vacuum conditions, in particular those directly concerned with surface phenomena on the monolayer level. Liquids have recently been subject to studies and several improvements and extensions of this technique can be done. Much advance has lately been achieved in the case of gases, wh...
Acetaldehyde has been studied by the technique of low-energy variable-angle electron energyloss spectroscopy. With this method the low-lying spin-forbidden transitions have been located via the behavior of the relative differential cross sections, providing the first identification by this technique of such states in acetaldehyde. High-lying states were also investigated and some assignments of...
The electronic structure of iron phthalocyanine (FePc) in the valence region was examined within a joint theoretical-experimental collaboration. Particular emphasis was placed on the determination of the energy position of the Fe 3d levels in proximity of the highest occupied molecular orbital (HOMO). Photoelectron spectroscopy measurements were performed on FePc in gas phase at several photon ...
