Electronic behavior of three oxygen non-stoichiometric Fe4+/Fe3+ oxoperovskites
For comparison with the Mn/Mn oxoperovskites at the crossover from localized to itinerant behavior of the s-bonding e electrons, the electronic properties of three oxygen non-stoichiometric, mixed-valent Fe/Fe oxoperovskites were explored by measuring their resistivity r(T), thermoelectric power a(T), and magnetic susceptibility w(T). Oxidation of Ca2Fe2O5 by annealing in ozone progresses by ox...
متن کاملAdsorption of alkanes on stoichiometric and oxygen-rich RuO2(110).
We investigated the molecular adsorption of methane, ethane, propane and n-butane on stoichiometric and oxygen-rich RuO2(110) surfaces using temperature-programmed desorption (TPD) and dispersion-corrected density functional theory (DFT-D3) calculations. We find that each alkane adsorbs strongly on the coordinatively-unsaturated Ru (Rucus) atoms of s-RuO2(110), with desorption from this state p...
متن کاملQuantitative and stoichiometric analysis of the microRNA content of exosomes.
Exosomes have been proposed as vehicles for microRNA (miRNA) -based intercellular communication and a source of miRNA biomarkers in bodily fluids. Although exosome preparations contain miRNAs, a quantitative analysis of their abundance and stoichiometry is lacking. In the course of studying cancer-associated extracellular miRNAs in patient blood samples, we found that exosome fractions containe...
متن کاملValidity of Peripheral Capillary Oxygen Saturation and Normal Mixed Venous Oxygen Tension in Measurement of O2 Content
Background The change in venous oxygen saturation occurs earlier, and even its reduction is faster than arterial oxygen saturation. The aim of this study was to validate SvO2 and PvO2 for O2 content measurement in children hospitalized w...
متن کاملPhotoluminescence and cathodoluminescence studies of stoichiometric and oxygen-deficient ZnO films
Photoluminescence and cathodoluminescence ~CL! spectra of stoichiometric and oxygen-deficient ZnO films grown on sapphire were examined. It was found that the intensities of the green and yellow emissions depend on the width of the free-carrier depletion region at the particle surface; the thinner the width, the larger the intensity. Experimental results and spectral analyses suggest that the m...
