Under the guidance of the Cockcroft–Latham damage theory, an integrated approach involving hot compression tests, numerical simulations and mathematic computations provides support to construct ductile fracture criteria diagram along with deformation conditions for Ti–10V–2Fe–3Al alloy. A series of compressions with a…
We have investigated the effect of nonmagnetic cap layers for Nd-Fe-B thin films with a small addition of rare-earth element. Remarkable enhancement of the coercivity was obtained for the Nd-Fe-B thin film on the epitaxially grown Mo buffer layer deposited at 500 °C followed by the postannealing at 550 °C. Especially,…
The objective of this study was to determine rheological behaviors of maple veneer plastic composite (MVPC) prepared by full cell preparation technology through the use of a rotational rheometer. The results showed that at 25 to 105 C, the storage modulus G' and loss modulus G'' of the MVPC were apparently higher than…
Abstract Molybdenum(VI) and tungsten(VI) dioxodiazide, MO2(N3)2 (M=Mo, W), were prepared through fluoride–azide exchange reactions between MO2F2 and Me3SiN3 in SO2 solution. In acetonitrile solution, the fluoride–azide exchange resulted in the isolation of the adducts MO2(N3)2⋅2 CH3CN. The subsequent reaction of MO2(N…
Herein the synthesis, spectroscopic characterization, two-photon absorption and electrochemical properties of 3,6-disubstituted carbazole tweezers is reported. A dimer resulting from a Glaser homocoupling was isolated during a Sonogashira coupling reaction between a diethynyl-carbazole spacer and a 5-bromo-triarylporp…
The conventional vibration welding process of polyamide 66 only has a continuous and steady melt flow during the quasi‐steady phase. The process and resulting welds have been thoroughly investigated. Radiation cross‐linking of polyamide 66 with electron beams alters the material's characteristics. Consequently, the re…
Abstract The crystal structures among M1–M2–(H)‐arsenites (M1 = Li+, Na+, K+, Rb+, Cs+, Ca2+, Sr2+, Ba2+, Cd2+, Pb2+; M2 = Mg2+, Mn2+,3+, Fe2+,3+, Co2+, Ni2+, Cu2+, Zn2+) are less investigated. Up to now, only the structure of Pb3Mn(AsO3)2(AsO2OH) was described. The crystal structure of hydrothermally synthesized Na4C…
Abstract The polymers [Cd(L)(H2O)] (1) and [Zn(L)(4, 4′‐bipy)(H2O)3] (2) (L = 2, 2‐dimethylsuccinated anion) were synthesized under hydrothermal conditions and characterized by IR spectrosopy, elemental analyses, and single‐crystal X‐ray diffraction analysis. The latter reveals that the polymer 1 exhibits a four‐conne…
Metal complexes derived from the reaction of Cu(II), Co(II), Ni(II) and Zn(II) acetates and (E)-4-(2-hydroxyphenylimino)pentan-2-one (H2L) have been synthesized and characterized by elemental analyses, MS, IR, UV-Vis., 1H NMR, thermal analyses (TGA and DTG) and magnetic measurements. In all complexes except for Zn(II)…
In this paper, we study a surface plasmon resonance (SPR) sensor with a microwell chip that is aimed at improving the sensitivity and reducing the noise. We present both theoretical simulations and experimental results obtained for the proposed structure. In comparison to most SPR sensors that use planar gold films, t…
Abstract Star‐shaped molecules consisting of regioregular poly(3‐hexylthiophene) (P3HT) chains as the arms, attached to either a propeller‐like triphenylamine or a planar triphenylbenzene core, have been synthesized via Suzuki coupling. The structures of the three‐arm star‐shaped poly(3‐hexylthiophene) (s‐P3HT) materi…
A systematic study of simulated atomic-resolution electronic energy-loss spectroscopy (EELS) for different graphene nanoribbons (GNRs) is presented. The results of ab initio studies of carbon [Formula: see text] core-loss EELS on GNRs with different ribbon edge structures and different hydrogen terminations show that…

Abstract The sulfide La4Cd4In2S13 in the quaternary RE/M/N/Q (RE = rare‐earth metal; M = Zn, Cd; N = Ga, In; Q = chalcogenides) system was prepared from stoichiometric mixtures of the elements by solid‐state reactions at 1223 K in an evacuated silica tube. The La4Cd4In2S13, crystallizing in the Pbam space group, is is…
We investigate the effect of topology on the equilibrium behavior of singly tethered ring polymers adsorbed on an attractive surface. We focus on the change of square radius of gyration Rg(2), the perpendicular component Rg⊥(2) and the parallel component Rg‖(2) to the adsorbing surface, the mean contacting number of m…
