Correlative microscopy and spectroscopy of perovskite mini-modules: degradation analysis
(2023)Perovskite materials have excellent prospects for semiconducting applications due to their desirable photoelectric properties. The morphology and the structure of the light absorption layer are crucially important for the ...

Detection of a photostable five-coordinate heme a3-Fe-Co species and functional implications of His384/α10 in CO-bound ba 3-cytochrome c oxidase from Thermus thermophilus
(2004)Resonance Raman (RR) spectra are reported for the fully reduced carbon monoxy derivative of ba3-cytochrome c oxidase from Thermus thermophilus. The RR spectra show the formation of a photolabile six-coordinate heme-CO and ...

Gamma radiation measurements and dose rates in commercially-used natural tiling rocks (granites)
(2003)The gamma radiation in samples of a variety of natural tiling rocks (granites) imported in Cyprus for use in the building industry was measured, employing high-resolution γ-ray spectroscopy. The rock samples were pulverised, ...

Magnetoexcitons in semiconductor quantum rings with complicated (Kane's) dispersion law
(2009)The influence of the nonparabolicity of charge carriers dispersion law (Kane's dispersion) on a magnetoexciton energy spectrum in InSb quantum rings is theoretically investigated. The analytical expression for the energy ...

Spectroscopic Study of the Hydrolysis of PuO22+ in Aqueous Solution
(1995)The hydrolysis of Pu(VI) is investigated under Ar atmosphere in the pH range between 4.5 and 9.0 at 22°C in 0.1 M NaC104 solution in contact with an initial solid phase, PuO2CO3(s). Under the given conditions, PuO2CO3(s) ...

Spin polarisation and anomalous Hall effect in NiMnSb films
(2004)NiMnSb has attracted a great deal of interest as a spin injector/detector in spintronic devices because it has a Curie temperature of 728 K and is predicted to be half-metallic (100% spin polarized). NiMnSb has been reported ...

A Study of Solid-Liquid Phase Equilibria of Pu(VI) and U(VI) in Aqueous Carbonate Systems
(1993)Solubility products of PuO2CO3(s) and UO2CO3(s) are determined in 0.1 M NaC1O4 at 22 1 C under 100%, 1 % and 0.03% CO2. The carbonate precipitates of Pu(VI) and U(VI), prepared under 100% CO2 at neutral pH, are characterized ...
