The RKKY interaction between two magnetic impurities absorbed on the surface layer of half-filled AB-stacked multilayer graphene (ABSMLG) is theoretically studied based on the lattice Green's function technique. In comparison with the case of monolayer graphene, the RKKY interaction in such multilayer graphene present…
The title compound crystallizes in the monoclinic P2(1)/c space group with a = 11.2470(3) Å, b = 5.9034(2) Å, c = 12.0886(3) Å, β = 115.143(1)°, and V = 726.58(4) Å(3) and consists of discrete monomeric NiCl(2)(o-phenylendiamine)(2) molecules. Each o-phen ligand coordinates in a bidentate mode with the chloride ions o…
In this paper, the polarity of binary solvents was studied by the sum law of cube roots of the dielectric constant. During the antisolvent crystallization process, the composition of the binary solvents and their dielectric constants changed simultaneously. These results demonstrated that variation of the solubility i…
A new design of a spherically molded liquid crystal cell intended for embedding in a contact lens is proposed. Wrinkle formation in these cells was investigated and a correlation was found between the total thickness of the cell and its smoothness. Smooth cells with minimal thickness were obtained by using an asymmetr…
Photochemical methods facilitate the generation, isolation, and study of metastable nanomaterials having unusual size, composition, and morphology. These harder-to-isolate and highly reactive phases, inaccessible using conventional high-temperature pyrolysis, are likely to possess enhanced and unprecedented chemical,…
Material science and catalysis play an important role in the chemical industry. Porous ceramics and metals are highly relevant in this field. There are plenty of applications for porous functional components, with engineered pores sizes ranging from micro to macro pores. A novel type of structured catalyst is introduc…
Abstract Lanthanide complexes with sulfonylamidophosphate‐type ligands: dibenzyl(phenylsulfonyl)amidophosphate (HSB) and di(4‐methylphenyl)‐phenylsulfonyl‐amidophosphate (HSK) have been synthesized and show promise as new sensitizers of visible and near‐infrared luminescence. They constitute a new part of coordination…
Recently, there has been a growing interest in protective textiles that are produced in order to reduce detrimental effects that arise from electric and magnetic fields on biological organisms and particularly on human health. The main goal of this investigation is to develop conductive metal-based yarns with desirabl…
An investigation into the effect of surface roughness on corona discharge for a 30-year operating conductor in the first 500-kV transmission line in China is presented. Many substances were found to adhere to the conductor surface. Corrosion and deposits had rendered the operated conductor surfaces much rougher than t…
Abstract Local vibrational modes (LVMs) and asymmetric phonon lineshapes are investigated in ZnO : Sb system. Two LVMs at 186 and 235 cm−1 originating due to the change in reduced mass and reduction of localized interatomic force constant have been identified. Upon Sb-doping, the E1(LO) mode of ZnO was found to shift…
A great deal of intensive research has been conducted to obtain high-quality transparent ultralow-refractive-index and ultralow-dielectric-constant thin films for microptics and microelectronics applications. Here, we report a simple procedure to prepare highly porous silica thin films with high optical quality and wa…
In this study, we calculate the interaction energy of intrinsic point defects vacancies and interstitials) with screw dislocations in body-centered cubic iron. First (we calculate the dipole tensor of a defect in the bulk crystal using molecular statics. Using a formulation based on linear elasticity theory, we calcul…
A capillary micro-reaction was established for the synthesis of Au-Ag alloy nanoparticles (NPs) with a flexible and controllable composition and grain size by tuning the synthesis temperature, the residence time, or the mole ratio of Au3+:Ag+. By extending the residence time from 5 to 900 s, enhancing the temperature…
Monodisperse palladium particles of six distinct and controlled sizes between 4–16 nm were synthesized in a one-pot polyol process by varying the molar ratios of the two palladium precursors used, which contained palladium in different oxidation states. This difference permitted size control by regulation of the nucle…
Foams generated via carbon dioxide (CO 2 ) processing typically exhibit a solid skin layer on the exterior surface and a closed-pore structure with limited interconnectivity in the core section thus limiting its application for biomedical intent. By controlling the properties of poly( l -lactic acid)/poly( d, l -lacti…
Under low electric fields, electrocaloric effects (ECEs) accompanied with the ferroelectric to paraelectric phase transition in ferroelectric [111]-oriented 0.955PbZn1/3Nb2/3O3–0.045PbTiO3 single crystals were simulated. The simulation predicted many interesting features of ECE, including the changes of entropy, heat…
Colloidal dispersions of silver bromide (AgBr) in aqueous surfactant medium have been prepared using a surfactant-assisted synthesis approach with hexadecyltrimethylammonium bromide (CTAB). The surfactant acts both as source of bromide ion as well as the stabilizing agent. Upon progressive addition of silver nitrate t…
Transparent conducting Al-doped ZnO (AZO)/nondoped ZnO/Cu2O heterojunction solar cells were fabricated by inserting a thin nondoped ZnO film as a buffer layer between an n+-AZO thin film and a p-Cu2O sheet prepared by thermally oxidizing a Cu sheet. The effect of inserting the buffer layer on the obtainable photovolta…
New molecules combining the functionalities of surface activity, polymerizability, and fluorescent properties within one molecule that could be seen as a fluorescent surfmer ( surf actant and mono mer ) were successfully synthesized. A long hydrocarbon tail capped with a methacrylamide unit was anchored to a mono- or…
