Voltage controlled magnetic anisotropy (VCMA)-induced precessional magnetization dynamics of a cross-shaped ferromagnet (FM) is studied by micromagnetic simulation. A cross-shaped FM, which has four minima in its energy landscape, can be used to store two bits. We show that, by selecting appropriate dimensions and tak…
The crystallization process of Se77.5Te15Sb7.5 glass is studied by differential scanning calorimetry (DSC) technique under non-isothermal conditions at various heating rates. The crystallization parameters are deduced using different models. The validity of the Johnson–Mehl–Avrami (JMA) model to describe the crystalli…
The work reports a facile synthesis procedure for preparation of porous sulfonated carbons and its suitability for adsorption of phenol. The sulfonated carbon was synthesized utilizing a simplified, single-step, shorter duration process by sulfonation, dehydration and carbonization of sucrose in sulfuric acid and tetr…
ABSTRACT The features of norbornene (NE) cross‐linked polyimide (PI) were investigated as the ratio of the norbornene monomer was varied. The coefficient of thermal expansion and modulus are important parameters of materials used in the microelectronic industry. Therefore, in this study, 5‐norbornene‐2, 3‐dicarboxylic…
Abstract This work investigates a decrease in mechanical properties of a polyamide‐based polymer, previously subjected to low‐cycle fatigue tests in strain control. Variations in its tensile stress response under monotonic loading and instantaneous elastic modulus were studied in relation with three loading parameters…
Abstract Blue monoclinic single crystals of the novel one‐dimensional [H 3 N‐(CH 2 ) 6 ‐NH 3 ][Cu(H 2 O) 2 (urea)(μ 2 ‐C 6 (COO) 4 (COOH) 2 )] · H 2 O coordination polymer were prepared in aqueous solution at room temperature in the presence of 1,6‐diaminohexane and urea [space group P 2 1 / n (no. 14) with a = 958.48…
A high-index-contrast grating (HCG) reflector is implemented in the polysilicon gate of a standard bulk CMOS for the first time. A transverse-electric (TE) preferred CMOS HCG reflector allows a >90% peak reflectivity, a 100-nm reflection bandwidth, and a 1.64:1 TE/transverse-magnetic polarization ratio, which is limit…
Abstract A series of lanthanide complexes with general formula [Ln(NTA)3X] were prapared [Ln = Y (a), Er (b), Eu (c), NTA = naphthoyltrifluoroacetone, X = H2O (1), phen = phenanthroline (2), bpyO1 = 2, 2′‐bipyridine N‐oxide (3), and bpyO2 = 2, 2′‐bipyridine‐N,N′‐dioxide (4)]. The crystal structures of [Eu(NTA)3bpyO2]…
HmbB, a predominantly mitochondrial high-mobility group box (HMGB) protein, of Aspergillus nidulans affects diverse biological activities, such as sterigmatocystin production, the maintenance of mitochondrial DNA copy number, germination of asexual and sexual spores, and protection against oxidative stress agents. We…
Published in Journal of Computational Chemistry 2015, 36, 151–163; DOI: 10.1002/jcc.23778 The additional corrections were to delete the red cross for the excitation energy at the BH&HLYP and CAM-B3LYP levels in Figure 7. Low-lying excited states with different computational levels and experimental data. The blue, gree…
The isothermal oxidation behaviour of a Ni25Cr model alloy was studied employing the JuSie-methodology, i.e. using specimens of different thickness for each specific test gas composition at 1000°C in dry and wet N2-1%O2 as well as in Ar-7%H2O. The oxidation mechanisms were evaluated using thermo-gravimetry and SEM/EBS…
In order to reveal the electron-electron correlation (interaction) effect in a Mott insulator VO2, we measured the temperature dependence of the thermopower, Hall effect, and Raman spectra in VO2 films and extracted the diverging effective mass from the thermoelectric behavior in the metal-insulator transition (MIT) r…
Longitudinal and transverse transport coefficients of the $\mathrm{Ba}{(\mathrm{F}{\mathrm{e}}_{1\ensuremath{-}x}\mathrm{C}{\mathrm{o}}_{x})}_{2}\mathrm{A}{\mathrm{s}}_{2}$ single crystals with $x=0,\phantom{\rule{0.28em}{0ex}}0.045,\phantom{\rule{0.28em}{0ex}}0.06$, and $0.244$ were measured in the temperature range…
Hybrid nanocomposites based on magnetic nanoparticles dispersed in liquid crystalline elastomers are fascinating emerging materials. Their expected strong magneto-elastic coupling may open new applications as actuators, magnetic switches, and for reversible storage of magnetic information. We report here the synthesis…
Combined X-ray diffraction (XRD), helium ion microscopy (HeIM), and 43 Ca nuclear magnetic resonance (NMR) results provide novel insight into the nano- and microstructure of flocculated NOM; the molecular-scale interaction among natural organic matter (NOM), dissolved Ca 2+ ions, and water in NOM floccs; and the effec…

This paper investigates the geometrical, electronic, and optical properties of a Ga24N24H46 nanoparticle using Density Functional Theory (DFT). The results show that this nanoparticle maintains geometrical parameters very similar to those of the GaN crystal, although it was noticed that the bond length along the direc…
Abstract In order to explore the influences of (de‐)protonation of the imidazole ring on the structural diversity of the resulting complexes, the imidazole‐based ligands 4, 5‐diphenylimidazole (Hdpi) and 1H‐phenanthro[9, 10‐d]imidazole (Hpi) were utilized as bulky building blocks to construct four complexes by solvoth…
