Abstract Hydroformylation, a reaction that adds carbon monoxide and dihydrogen across an unsaturated carbon–carbon multiple bond, has been widely employed in the chemical industry since its discovery in 1938. In contrast, the reverse reaction, retro‐hydroformylation, has seldom been studied. The retro‐hydroformylation…
A judicious material constitutive model used as input to the numerical codes to denote elastic, plastic, and thermomechanical behavior under elevated temperatures and strain rates is essential to analyze and design a process. This work describes the formulation of different constitutive models, such as Johnson–Cook, Z…
The β-diketiminato aluminum-monohydroxide and -dihydroxide were reacted with tetrameric (CuMes)4 (Mes = 2,4,6-Me3C6H2) to prepare Cu(I) complexes bearing the Al-O-Cu moiety. All complexes are characterized by elemental analysis, nuclear magnetic resonance, and single-crystal X-ray diffraction. The reaction of aluminum…
A novel semiorganic non-linear optical crystal, l-lysine hydrochlorobromide (LYHCBr) dimensions of 1 × 0.2 × 0.2 cm was grown by deionised water by the conventional method. l-lysine hydrochlorobromide crystallises in non-centrosymmetric orthorhombic crystal system with space group P212121.FTIR spectrum analysis was ex…
We develop a hierarchy of approximations to the master equation for systems that exhibit translational invariance and finite-range spatial correlation. Each approximation within the hierarchy is a set of ordinary differential equations that considers spatial correlations of varying lattice distance; the assumption is…
A new method to calculate the surface interaction energy of ceramic particles and epoxy resin network was investigated using the Material Studio software solution. Detailed simulations were performed with molecular dynamics (MD) method, using Amorphous Cell module, creating relatively simple surface models of polymer…
Abstract Development of highly active, low cost, ecologically friendly, and durable homogenous catalysts for hydrogen generation from hydrolysis of borohydride is one of the most desirable pathways for future hydrogen utilization. The unexpected catalytic activities of inorganic ammonium species and the corresponding…
Silver nanoparticles plating multiwalled carbon nanotubes were synthesized by electroless plating method. The electrically conductive acrylate pressure-sensitive adhesive filled with silver nanoparticles plating multiwalled carbon nanotubes was prepared using the solution blending method. Characterization of morpholog…
This work investigates the electromechanical response of poled barium titanate (BaTiO3) polycrystals with oxygen vacancies at room temperature. A phase field model is developed for ferroelectric polycrystals, coupled with the time-dependent Ginzburg-Landau theory and the oxygen vacancies diffusion, to demonstrate the…
We report the systematic structural manipulation of turbostratic electrospun carbon nanofibers (ECNFs) using a microwave-assisted oxidation process, which is extremely rapid and highly controllable and affords controlled variation of the capacitive energy storage capabilities of ECNFs. We find a nonmonotonic relations…
For a series of nanometric ZnO materials, the relationship between their morphological and surface functionalities and their catalytic properties in the selective decomposition of ethanol to yield acetaldehyde was explored. Six ZnO solids were prepared by a microemulsion-precipitation method and the thermal decomposit…
In wood products industry, the diversity of wood based panel products is increasing day by day, and composite (sandwich) materials in honeycomb and foam structure have an important place among these. The lightness, flexibility and resistance properties on the site of utilization are the major advantages of these produ…
Anatase TiO${}_{2}$ is of great interest for applications spanning photovoltaics, memristor electronics, and catalysis. Among its interesting properties is ${d}^{0}$ ferromagnetism: Undoped samples can be intrinsically, strongly magnetic at room temperature, despite a nominally diamagnetic electronic structure. The au…
N-doped and Al-N dual-doped ZnO thin films have been synthesized on glass substrate by low-cost spray pyrolysis technique. Introduction of N and Al in ZnO affects the surface morphology and electro-optical properties of ZnO. SEM micrographs clearly show the formation of nano-scale semi-spherical and hexagonal crystall…
ABSTRACT Two polyarylaminophosphazenes, poly[bis(phenylamino)phosphazene] (PBAP) and poly[bis( p ‐trifluoroethoxyphenylamino)phosphazene] (PBTAP), were successfully synthesized by ring‐opening polymerizations and nucleophilic substitution reactions. Their chemical structures, thermal properties, and surface properties…
In dilute magnetic semiconductors studies, sapphire was usually used as non-magnetic substrate for films. We observed weak ferromagnetic component in Al2O3 single crystal substrate, and excluded the possibility of ferromagnetic contaminations carefully by inductively coupled plasma mass spectrometry and X-ray photoele…
Abstract A new method to develop two‐dimensional PANI nanosheets using ice as a removable hard template is presented. Distinctly high current flows of 5.5 mA at 1 V and a high electrical conductivity of 35 S cm −1 were obtained for the polyaniline (PANI) nanosheets, which marked a significant improvement from previous…
The catalytic activity of oxide-supported vanadium oxide is improved by the presence of tungsten oxide for the selective catalytic reduction of nitric oxides. We propose a mechanism for V–W synergy through studies of the reduction–oxidation behavior of near-monolayer VO X and WO X species grown by atomic layer deposit…
Herein, we designed four peptides appended with different numbers of histidine (Hisn -peptide). We launched a systematic investigation on quantum dots (QDs) and Hisn -peptide self-assembly in solution using fluorescence coupled CE (CE-FL). The results indicated that CE-FL was a powerful method to probe how ligands int…
Correlation of structure and ion conduction of La2−xYxMo2O9 (0 ≤ x ≤ 0.2) has been investigated. The cubic symmetry with space group P213 and other structural parameters are obtained from Rietveld refinement of X-ray diffraction patterns of Y doped samples. The average lanthanum-oxygen and molybdenum-oxygen distances…
