The increasing demands on reliability, safety and economics of nuclear systems translate to challenges in realization of high-performance components for operation at steady state, transient and severe accident conditions. The authors, based on their four decades of research, development and deployment experiences, pre…
The single-crystal X-ray diffraction data, binding behavior, and epoxidation reactions of the cavitand resorcin[4]arene–porphyrin conjugate are presented.
A simultaneous <italic>in situ</italic> determination of phenanthrene and fluoranthene adsorbed onto root surfaces was established, and the transport of PAHs from root surface to tissues was investigated.
To analyze the controversial conclusions on the magnetism of C-doped SnO2 (SnO2:C) bulk materials between theoretical calculations and experimental observations, we propose the critical role of the charge states of defects in the geometric structures and magnetism, and carry out a series of first principle calculation…
Herein a novel strategy to tune the crystallite orientation and the ionic conductivity of solid electrolyte films through interfacial control has been reported. 10 mol% Sc2O3-doped ZrO2 (10ScSZ) thin films were prepared with an amorphous alumina (AO) interlayer (AO/10ScSZ) using magnetron sputtering. It has been found…
We use the tip of a scanning tunneling microscope (STM) to manipulate single weakly bound nanometer-sized sheets on a highly oriented pyrolytic graphite (HOPG) surface through artificially increasing the tip and sample interaction by pretreatment of the surface using a liquid thiol molecule. By this means it is possib…
Graphene oxide could be efficiently reduced to graphene on Cu electrode through a novel electrocatalytic solid-to-solid reaction.
Point defects and nanoscale interfaces effectively scatter short and mid-to-long wavelength phonons, respectively, thereby considerably reducing the thermal conductivity. In this paper, a classical physical model of phonon transport and scattering, the Callaway and von Bayer method, is recast with the introduction of…
Rare Earth- (RE-) doped BiFeO 3 (BFO) thin films were grown on LaAlO 3 substrates by using pulsed laser deposition technique. All of BFO films doped with 10% of RE show a single phase of rhombohedral structure. The saturated magnetization in the Ho- and Sm-doped films is much larger than those reported in literature a…
In this study, the thermal and electrical conductivity properties of carbon black coated cotton fabrics were investigated. To obtain coated cotton fabrics, first carbon black nanoparticles were dispersed in distilled water. To improve dispersion stability of water based carbon black coating solutions, anionic wetting…
The curing behavior of lignin-based phenol-formaldehyde (LPF) resin with different contents of nano-crystalline cellulose (NCC) was studied by differential scanning calorimetry (DSC) at different heating rates (5, 10 and 20°C/min) and the bonding property was evaluated by the wet shear strength and wood failure of…
Multiferroic 0.6BaTiO 3 ‐0.4NiFe 2 O 4 dense nanoceramic composites were synthesized via a powder‐in‐sol precursor hybrid chemical synthesis route and a ceramic sintering process. At the measured frequency range (1 kHz~1 MHz), the relative dielectric constant is 150~1670 and the dielectric loss is 0.05~0.70. The compo…
The catalytic activity in the soot combustion is reported for a series of potassium-promoter alumina supported catalysts prepared by the sol-gel method to be used in the catalytic combustion of soot. The studied systems correspond to CeO2-Al2O3 and La2O3-Al2O3 with charges of 3 and 5 wt% of CeO2 and La2O3. Potassium i…
The major differences between the physics models in Geant4-DNA and RITRACKS Monte Carlo packages are investigated. Proton and electron ionisation interactions and electron excitation interactions in water are investigated in the current work. While these packages use similar semiempirical physics models for inelastic…
We propose a broadband perfect polarization conversion metasurface composed of copper sheet-backed asymmetric double spilt ring resonator(DSRR).The broadband perfect polarization convertibility results from metallic ground and multiple plasmon resonances of the DSRR.Physics of plasmon resonances are governed by the el…
Toughened thermal blankets have been developed that greatly improve protection from hypervelocity micrometeoroid and orbital debris (MMOD) impacts. Three types of materials were added to the thermal blanket to enhance its MMOD performance: (1) disrupter layers, near the outside of the blanket to improve breakup of the…
Nanocrystalline ZnO:Al nanoparticles are suitable building blocks for transparent conductive layers. As the concentration of substitutional tetrahedral Al is an important factor for improving conductivity, here we aim to increase the fraction of substitutional Al. To this end, synthesis parameters of a solvothermal re…
Abstract Activated carbon monoliths with different surface characteristics were prepared by impregnating oil palm stone with diluted aqueous CaCl 2 solutions (with concentrations between 2 and 7% w/v) without binders. The solids were characterized by determination of nitrogen adsorption isotherms at 77 K and carbon di…
The calculation of eddy current losses in foil windings exposed to a 2-D fringing field is a complex task because of the current displacement along the height of the foil. For model-based optimization of magnetic components, loss calculation with 2-D finite element method simulation is not an option because of the hig…
Mesocrystal formation is one of the new paradigms of the nonclassical crystallization, where the assembly of crystal domains is observed. Also, it has been recently employed in studies on drug formulation to utilize controlled dissolution of the drug domains. In this report, ibuprofen was attempted to form hybrid meso…
