Abstract Eu2Mo2O7 (I) is synthesized from a stoichiometric mixture of Eu2O3, MoO2, and Mo (alumina boat, flowing Ar, 1450 °C, 14 h) and EuMoO4 (II) from a stoichiometric mixture of Eu2O3, MoO3, and Mo (quartz tube, 600 °C, 24 h, and 1050 °C, 36 h).
Abstract The title system is studied with focus on the NdPO4—K3PO4—KPO3 partial system and the phase diagram of this region is constructed.
Abstract Compounds (I) can serve as naked eye detector of fluoride anions.

In the present work, the formation of ultrafine grained ferrite has been studied by applying suitable thermomechanical treatment. A high amount of deformation (∼80%) at varying strain rates (0·01–10 s−1) was applied in the temperature range of Ar3 to Ac3 followed by water quenching. This treatment resulted in a two-ph…

Abstract A series of hydroxy‐ and nitro‐substituted diphenyl ethers are prepared as novel tyrosinase inhibitors.
The electro-optic characteristics of Liquid Crystal Displays (LCDs) are deeply affected by those parameters including the kinds of liquid crystals and alignment layer materials, the forming conditions of alignment layer, the substrates alignment mode and the processing conditions of rubbing alignment in the interface…

Back Cover: The picture presents stimuli-responsive polymers, which are able to show responses to various environmental changes. Among those stimuli, light has attracted much attention since it can be localized in time and space, and it can also be triggered from outside the system. In the related feature article, lig…
Abstract Single crystals of the title compound are prepared in molten Na from mixtures of NaN3, Na, Sr, Ge, Ga, and Li (Na:Sr:Ge:Ga:Li = 13:0.5:1:1:0.5; 760 °C, 48 h) Na5GaGe2 crystallizes in the monoclinic space group P21/m with Z = 2.

The composite containing 10 wt% of osteoconductive porcine cortical bone (PCB) and 90 wt% of bioabsorbable poly(L-lactide) (PLLA) was manufactured. The degradation behaviors of the PLLA/PCB composite in-vitro up to 20 weeks, including water uptake, weight loss, mechanical properties, molecular weight and morphology, w…
Abstract The title compound is characterized by neutron powder diffraction between 1.4 and 12.0 K and heat capacity measurements.
In addition to the well known ferromagnetism, double perovskites are also expected to exhibit antiferromagnetic (AF) order driven by electron delocalisation. This has been seen in model Hamiltonian studies and confirmed via ab initio calculations. The AF phases should occur, for example, on sufficient electron doping…
We have investigated dynamical heterogeneity in a highly supercooled liquid using molecular-dynamics simulations in three dimensions. Dynamical heterogeneity can be characterized by three quantities: correlation length $\xi_4$, intensity $\chi_4$, and lifetime $\tau_{\text{hetero}}$. We evaluated all three quantities…
Nos estudamos os efeitos da quebra de simetria e de desordem no espectro de energia de um eletron numa bicamada de grafeno. O problema foi abordado atraves de simulacoes numericas considerando um Hamiltoniano tight-binding para uma rede retangular topologicamente equivalente a rede hexagonal do grafeno que nos permite…
Les carbones nanostructurés sont très largement utilisés dans les systèmes de stockage et conversion d'énergie par voie électrochimique, par exemple en tant que matériau d'électrode de pile à combustible et de batterie ou encore de supercondensateur. La structure du carbone ainsi que sa chimie de surface sont des para…
Une série de films Ti1-xAlxN (0 ≤ x ≤ 1, teneur en Al) de différentes épaisseurs (300 – 500 et ≃ 2000 nm) a été déposée par pulvérisation magnétron en atmosphère réactive sur des substrats en Si(l 00) et en acier rapide. Des indentations Vickers ont été réalisées sur les films déposés sur acier à des charges de 0,5 et…
