The title compound, [Ho(2)(C(9)H(9)O(3))(6)(C(12)H(8)N(2))(2)], lies about a centre of symmetry and is comprised of six 2-phen-oxy-propionate (POPA) anions and two 1,10-phenanthroline (phen) ligands. The two Ho(III) ions are linked by four POPA groups utilizing both bi- and tridentate bridging modes to form an inversi…

Polymeric materials, such as polyurethanes (PUs) are traditionally derived from petrochemical polyols but as oil reserves are depleting and prices continue to rise, the development of alternatives is becoming necessary. Vegetable oil-based polymers are gaining popularity due to some attractive properties (e.g. viscosi…
We suggest a phenomenological theory of the polarization conversion effect, an excitonic analog of the birefringence phenomena, which is, however, observed in the photoluminescence rather than in the passing light. The optical polarization response of a model system of electrically neutral quantum dots subject to the…
Abstract The compounds LnPtZn (Ln: Y, Pr, Nd, Gd—Tm) are prepared from the elements by high‐frequency melting (Ta tubes, 1500 K) followed by annealing (1120 K, 4 h) and quenching.
Cu films were prepared by arc ion plating (AIP) at low temperature ( T s ) and investigated by X-ray diffraction, field emission scanning electron microscope atomic force microscopy, transmission electron microscope, etc. It is found that low T s (≤ 221 K) can refine the crystallite size of the Cu films and leads to c…
This article describes how eight different salts impact the rheological behavior of an aluminum titanate‐based ceramic paste. A capillary rheometer was used to measure the thermal phase transition temperature of a hydroxypropyl methylcellose binder in the paste. The transition of the binder causes the paste to increas…
A zone-resolved photoelectron spectroscopy (ZPS) has enabled us to gain the local and quantitative information and hence confirm our theoretical expectations on the bonding and electronic dynamics at graphite skin with and without atomic vacancy defects. The ZPS study has revealed: i) the 1s energy level of an isolate…
Standard test methods such as those published in American Society for Testing and Materials (ASTM)/Institute of Petroleum/Universal Oil Product are often used to characterize the fuel's properties. However, these chemical/physical characterization methods are not only expensive and protracted but also require a large…
Abstract The title perovskite oxide based cathode materials are prepared by a gel‐combustion method from aqueous solutions of stoichiometric amounts of the metal nitrates using glycine as a fuel (sintering at 1673 K for 10 h).
The structure of interfaces plays an important role in determining the electronic properties of semiconductor nanostructures. Here, such examples are shown and discussed using semiconductor nanostructures prepared by molecular beam epitaxy and colloidal synthesis.
Jürgen Hafner started in the early 1970s with pseudopotential calculations on the structures and properties of sp -bonded metals, improving on work done elsewhere [ 1 ]. This expanded in four directions: transition metals, molten metals, magnetism and alloys, and combinations of these. As well as electronic structure…
The performance of a H2S solid oxide fuel cell with proton conductor electrolyte, which is constructed by Co-Mo metal sulfide as an anode electro-catalyst, was tested at different Co/Mo ratios. The results indicate that the maximum power output, 6.0 mW · cm−2, was obtained at Co:Mo = 2:3, the next is 5.2 mW · cm−2 at…
The aim of this thesis is to contribute to a better understanding of the health effects of chronic extern allow doses of ionizing radiation. This work is based on the French cohort of CEA-AREVA NC nuclear workers. A review of epidemiological studies on nuclear workers was conducted during the first yearof the PhD thes…
Abstract An oxygen‐deficient BiMnO2.81 sample in bulk form is prepared by low‐temperature vacuum reduction of stoichiometric BiMnO3 (10‐4—10‐3 Pa, 570—600 K, 5 h).
Abstract Ba3Cu15.1S7.92Te3.08 (I), Ba3Cu15.7S7.051Te3.949 (II), Ba3Cu15.6S5.33Te6.17 (III), and Ba3Cu16.0S4.45Te7.05 (IV) are synthesized from stoichiometric mixtures of the elements at 1073 K (6 h, slow cooling to 873 K over 100 h).
The influence of an ellipsoid on the angular order of two-dimensional classical clusters is investigated through Brownian dynamics simulations. We found the following: (1) The presence of an ellipsoid does not influence the start of the angular melting, but reduces the rate at which the inner rings can rotate with res…
The theoretical magnetization hysteresis curve of Nd-Fe-B anisotropic bonded magnets is simulated using Jiles-Atherton model and random number generation technique. Gaussian statistics was used to assign magnetic particles to random values of magnetic field (H$_{ai}$) and effective interaction ($\alpha )$ parameters.…
The title complex, [(C(4)H(9))(4)N](2)[Mo(6)(C(7)H(6)ClN)O(18)], was prepared by the reaction of (Bu(4)N)(4)[α-Mo(8)O(26)] and 2-methyl-5-chloro-aniline hydro-chloride with N,N'-dicyclo-hexyl-carbodiimide as dehydrating agent in dry acetonitrile solution. The aryl-imido ligand is linked to an Mo atom of the Lindqvist-…
