The interactions of nitric oxide gas with thin layers of Fe(II)(TPP) and Ru(II)(TPP), obtained by sublimation onto low-temperature substrate (77 K), has been investigated by means of IR spectroscopy (TPP = meso-tetraphenylporphyrinate). Only simple addition of NO to form Fe(TPP)(NO) is observed for the iron-porphyrin…
We investigate theoretically charge ordered states on the anisotropic triangular lattice characteristic of the theta-(BEDT-TTF)_2 X materials. Using exact diagonalization studies, we establish that the charge order (CO) pattern corresponds to a ``horizontal'' stripe structure, with ...1100... CO along the two directio…

Comb-shaped supramolecules are constructed using flexible polymers and semi-rigid conjugated undoped or doped conjugated polymers upon complexing Zinc dodecyl benzene sulphonate, Zn(DBS)2. Selforganized nanostructures are formed in the bulk due to competing attractive interactions (coordination or water mediated hydro…
To improve the nuclear performance of fusion breeding blankets, the application of thermal type blankets with 6Li-enriched ceramics and low-activation ferritic steel is suggested. However, appropriate neutronics experiments to investigate the nuclear performance of such blankets have never been carried out. Therefore,…
Abstract Early‐stage interfacial reactions were studied in three different heat‐treated oxide/metal bilayers (the oxide is amorphous (a) TiO 2 and the metal is crystalline (c) Ti, c‐Ti 3 Al or amorphous a‐TiAl) by means of Auger electron spectroscopy (AES) depth profiling. The oxide/metal bilayers were sputter deposit…
Abstract The synthesis of polyetheramide, containing poly(tetramethylene ether) (PTMEG) as the soft segment phase and polylactams as the hard phase was carried out in a Leistritz modular intermeshing counter‐rotating twin‐screw extruder in a one‐step, solvent‐free process. No by‐product such as carbon dioxide or H 2 O…
Abstract Reactive blending of poly(ethylene terephthalate)/poly(ethylene naphthalene 2,6dicarboxylate) with addition of 2,2'‐bis(1,3‐oxazoline) (BOZ) has been studied under various mixing conditions for the different compositions. The transesterification level, the sequence length of both PET and PEN short blocks, and…
Abstract X‐ray photoelectron spectra of free‐electron metals such as magnesium and aluminium contain pronounced electron energy‐loss peaks due to plasmon excitations. Part of the intensity contained in these plasmon peaks is of an intrinsic nature. In this work a procedure is presented that allows the determination of…

The signal-to-noise ratio required to obtain 10-nm accuracy inthe measurement of lateral position is studied with an interference mi-croscope. Evaluations are performed using th…
The spin-spin interaction of Dy3+ ions in a KY(WO4)2 single crystal is investigated by electron paramagnetic resonance (EPR) spectroscopy at a temperature of 4.2 K and a frequency of 9.2 GHz. The EPR spectra of ion pairs located in different coordination shells are analyzed. It is revealed that the considerable contri…
Abstract The complete nickel-indium system was thermodynamically assessed at a total pressure of 1 bar from room temperature up to liquidus temperatures. The Gibbs energies of five condensed soluti...
Two routes currently exist for the commercial production of primary magnesium: thermal and electrolytic. The electrolytic process accounts for 75% of the Western world's production capacity and this level is expected to increase if known magnesium projects materialize in the near future. Commercial applications of the…
Ten hausmannite crystals (from Ilfeld and Friedrichrode, Harz, Germany), belonging to the (Mn 1-x Zn x )Mn 2 O 4 (0 ≤ x ≤ 0.26) system (I4 1 /amd hausmannite structure type), were characterized by chemical (electron microprobe) and structural (single-crystal X-ray diffractometer) analysis. The prevailing trivalent cat…
In this work, alternative heterojunction devices to be used for gamma-radiation detection are presented. The high quality silicon/polyaniline heterostructures use polyaniline thin films as an active part of the device structure. Polyaniline thin films 40 nm thick were deposited onto silicon substrates (n-type, <100>,…
X-ray diffraction experiments are used to obtain short-range order information of gallium phosphate glasses of meta- and pyrophosphate compositions. Parameters of the first-neighbor peaks, such as coordination numbers and distances, are obtained. A strong decrease of the Ga-O coordination number from 6.0±0.2 to 4.6±0.…
The crystal structure of a lutetium silicon oxynitride (Lu 4 Si 2 O 7 N 2 ) was analyzed by the Rietveld method using time‐of‐flight (TOF) neutron powder diffraction data. The compound crystallizes in a monoclinic cell, space group P 2 1 / c (No. 14‐1) with a = 7.4243(1), b = 10.2728(1), c = 10.6628(1) Å, and β= 109.7…
Janis (Java-based nuclear information software) is a display program designed to facilitate the visualisation and manipulation of nuclear data. Its objective is to allow the user of nuclear data to access numerical and graphical representations without prior knowledge of the storage format. It offers maximum flexibili…
La burnsite, dont la formule ideale est KCdCu 7 O 2 (SeO 3 ) 2 Cl 9 , a ete decouverte dans une fumerolle dans la breche du Nord de la grande eruption fissurale du volcan Tolbachik (1975-1976), dans la peninsule de Kamchatka, en Russie. Elle se presente en grains rouge fonce, xenomorphes, equidimensionnels. Lui sont a…
Abstract Adsorption of phenols (phenol and 2-naphthol) onto the 1,1′-dimethyl-4,4′-bipyridinium (methylviologen:MV2+)-smectite intercalation compounds, which were synthesized by ion exchange reactions, led to the change in the color and the basal spacing. The color change was ascribed to the formation of charge-transf…
