Ba 3 NbFe 3 Si 2 O 14 single crystals of promising multiferroic properties from the langasite family have been grown by floating zone melting. The accurate high-resolution X-ray diffraction studies of this crystal were performed on a diffractometer with a two-dimensional CCD detector at 293 and 90.5 K. To compensate s…
Hazelnut husk was considered as a potential filler for thermoplastic composites. Different amounts of hazelnut husk flour and the recycled high-density polyethylene (R-HDPE) were used as the filler and polymer matrix, respectively. The composite compounds were produced using single-screw extrusion compounding, and the…
PURPOSE: To quantify and explain the backscatter dose effects for clinically relevant high atomic number materials being irradiated in the presence of a 1.5 T transverse magnetic field. METHODS: Interface effects were investigated using Monte Carlo simulation techniques. We used gpumcd (v5.1) and geant4 (v10.1) for th…
We have investigated the charge transfer mechanism in single crystals of DTBDT-TCNQ and DTBDT-F4TCNQ (where DTBDT is dithieno[2,3-d;2',3'-d'] benzo[1,2-b;4,5-b']dithiophene) using a combination of near-edge X-ray absorption spectroscopy (NEXAFS) and density functional theory calculations (DFT) including final state ef…
The thermal fractionation kinetics of a linear low-density polyethylene (LLDPE) during Successive Self-Nucleation and Annealing (SSA) is investigated by fast scanning chip-calorimetry (FSC), by systematically varying the holding times (ts) at each fractionation temperature (Ts). The range of explored fractionation tim…
Responsiveness to environmental stimuli is a phenomenon that characterizes living cells and organisms and relates to fundamental principles of life. It is of great interest to understand this complicated and multifactorial mechanism, in order to build multifunctional biomaterials and devices, like drug nanocarriers. B…
The adsorption and corrosion inhibitive effect of the ethanol extract of Funtumia elastica (FE) leaves on mild steel corrosion in 0.5 M H 2 SO 4 was studied using gravimetric, potentiodynamic polarization and electrochemical impedance spectroscopic techniques. As well as Fourier transform infrared spectroscopy and com…
Two new ternary copper‐containing arsenides, Sr 2 Cu 3 As 3 and Eu 2 Cu 3 As 3 , were synthesized through Pb‐flux reactions. In combination with theoretical calculations, the crystal structures of these compounds were determined through single‐crystal X‐ray diffraction. Both compounds crystallize in the orthorhombic s…
The stresses in thin films are one of the main problems in the development of small dimensions or thin optical components. In order to produce low-tension anisotropic coatings, the characterization of serial bideposition is essential. Structural and optical performance have been tested for anisotropic TiO2 thin films…
Understanding the reactivity of H2 is of critical importance in controlling and optimizing many heterogeneous catalytic processes, particularly in cases where its adsorption on the catalyst surface is rate-limiting. In this work, we examine the temperature-dependent adsorption of H2/D2 on the clean RuO2(110) surface u…
Titanium-doped diamond-like carbon (DLC) films with electrical conductivity are prepared by plasma-enhanced chemical vapor deposition using high-density pulsed Ar/C2H2 plasmas. Those plasmas are produced by high-power pulsed magnetron sputtering (HPPMS) system, whereas the titanium dope into the DLC films is carried o…
Plasma polymerized a-C:H thin films have been deposited on Si (100) and aluminum coated glass substrates by a dielectric barrier discharge (DBD) operated at medium pressure using C2Hm/Ar (m = 2, 4, 6) gas mixtures. The deposited films were characterized by Fourier transform infrared reflection absorption spectroscopy…
Abstract We report a unique successive hydrothermal deposition method for the heteroepitaxial growth of well‐dispersed crystalline Co 3 O 4 nanoparticles on single‐crystalline porous ZnO nanoplates toward a Co 3 O 4 /ZnO nanocomposite catalyst. The specific heteroepitaxial crystal faces between Co 3 O 4 and ZnO limit…
It is recognized that “the bridge-building technique remains an art”, due to unclear microscopic nature of the bridging-spillover mechanism. In this paper, a theoretical model of a carbon bridge is designed to reveal the bridging-spillover mechanism in covalent organic frameworks (COFs) by the first-principles calcula…
High Resolution Image Download MS PowerPoint Slide A simple, one-pot method to fabricate ordered, monodispersed Pd–CeO 2 colloidal assembled spheres (CASs) was developed using the surfactant-mediated solvothermal approach, which involves a tunable self-assembled process by carefully controlling different chemical reac…
Conventional shape memory polymers suffer the drawbacks of low thermal stability, low strength, and low shape recovery speed. In this study, main-chain liquid crystalline polyurethane (LCPU) that contains polar groups was synthesized. Graphene oxide (GO)/LCPU composite was fabricated using the solution casting method.…
Octreotide had been exploited as a targeting ligand for nanoparticle tumor localization overexpressing somatostatin receptor. In addition to particle size and other physiochemical properties, ligand density had great influence on the delivery of active targeted nanoparticles. Herein, octreotide-targeted liposomal doxo…
A polarization-mediated color filter featuring a high angular tolerance is proposed incorporating a metal-dielectric-metal etalon based on a nanostructured cavity, where a one-dimensional subwavelength grating of a high refractive index is embedded in a base layer of a low refractive index. The aim of the nanostructur…
Accurate measurement of thermal conductivity is essential to determine the thermoelectric figure‐of‐merit, zT . Near the phase transition of Cu 2 Se at 410 K, the transport properties change rapidly with temperature, and there is a concurrent peak in measured heat capacity from differential scanning calorimetry (DSC).…
Bioinspired design concept has been recognized as one of the most promising strategies for discovering new biomaterials. However, smart biomaterials that are of growing interests in biomedical field need biological processability to meet their emergent applications in vivo. Herein, a new bio-orthogonally deciphered ap…
