Perovskite oxide SrSnO 3 has attracted considerable attentions recently due to its high carrier mobility and high transparency. Here, we experimentally and theoretically investigated the effects of La and Pb doping on the microstructure, band gaps, and electrical properties of SrSnO 3 epitaxial thin films. X-ray diffr…
A series of high solid content carboxylic acid/sulfonic acid waterborne polyurethanes was prepared by the emulsion dispersion method. The particle size and solid content were measured. By changing the particle size of the large particles to achieve different particle size ratios, high solid content waterborne polyuret…
The Electrochemical frequency modulation and Reactivation investigation results have shown that the anticorrosion inhibitors of 3a,6a- bistolylthioglycoluril, 4,5-dihydroxy-4,5-bistolylimidazolidine-2-thione and 5,5-bistolyl-2-thione-4-imidazolidone maximally reduced H + impacts on metal surface so these inhibitors ha…
The effect of assemblies bowing in PWR nuclear reactors onto core neutronics is an observed phenomenon still poorly understood which can lead to Power Ratio Tilt. Studies of the consequences of rod/assembly bowing involve many different fields addressed by nuclear power plant, such as neutronics, thermohydraulics, mec…
An electrochemical model was developed to predict the transient distribution of species generated during corrosion of a carbon steel/AA7075 aluminum alloy galvanic couple . Both metals were set under a confined electrolyte layer of thickness 50 μm containing ten interacting chemical species . The model was solved by t…
). The HMM-supported angularly selective system could find promising applications for high-efficiency light manipulation and lensless on-chip imaging.
Abstract Two-dimensional transition-metal dichalcolgenides (2D-TMDs) are among the most intriguing materials for next-generation electronic and optoelectronic devices. Albeit still at the embryonic stage, building thin films by manipulating and stacking preformed 2D nanosheets is now emerging as a practical and cost-e…
How ferroelectric (FE) and antiferroelectric (AFE) domains interact under an electric field is interesting, given the coexistence of FE and AFE phases in technologically important compositions. Work on AFE oxides has focused on the field-induced AFE-to-FE phase transition, though, as such a global event can be readily…
Six different rare-earth oxyapatites, including Ca 2 RE 8 (SiO 4 ) 6 O 2 ( RE = La, Nd, Sm, Eu, or Yb) and NaLa 9 (SiO 4 ) 6 O 2 , were synthesized using solution-based processes followed by cold pressing and sintering. The crystal structures of the synthesized oxyapatites were determined from powder X-ray diffraction…
An electrical double layer typically behaves as a constant phase element (CPE) rather than a pure capacitor. To separate the non-faradaic current contributed by the electrical double layer from the total current, which is obtained from cyclic voltammetry using modeling, the CPE parameters—the CPE parameter (Y0) and th…
We estimate the liquid-vapor surface tension from simulations of TIP4P/2005 water nanodroplets of size N = 100 to 2880 molecules over a temperature T range of 180 K–300 K. We compute the planar surface tension γp, the curvature-dependent surface tension γs, and the Tolman length δ, via two approaches, one based on the…
Influence of annealing on the microstructure and mechanical properties has been studied for Al–Zr (0.4 wt.%) alloy with the ultrafine-grained (UFG) structure formed by high-pressure torsion (HPT) at room temperature. A drastic hardening effect by short-term annealing in the temperature range of 90–280°С was observed f…
A family of compounds, A 3 BC 3 D 2 O 14 (A = Ba, Pb; B = Te, Sb; C = Al, Ga, Fe, Zn; D = Si, Ge, P, V), with the Dugganite structure was prepared employing traditional solid-state chemistry methods. PXRD and Rietveld refinement studies indicate that the compounds are stabilized in P 321 space group (no. 150). The com…
Abstract The architectures of biological hard materials reveal finely tailored complex assemblies of mineral crystals. Numerous recent studies associate the design of these local assemblies with impressive macroscopic response. Reproducing such exquisite control in technical ceramics conflicts with commonly used proce…
Multilayer thin films have the potential to act as high dielectric strength insulation for wire and microelectronics. In this study, films consisting of 2, 4 or 8 layers, composed of Al 2 O 3 with SiO 2 or Ta 2 O 5, were prepared via pulsed direct current and radio frequency magnetron sputtering to a thickness of betw…
Owing to its outstanding electro-thermal properties, such as the highest thermal conductivity (22 W/(cm∙K) at room temperature), high hole mobility (2000 cm2/(V∙s)), high critical electric field (10 MV/cm) and large band gap (5.5 eV), diamond represents the ultimate semiconductor for high power and high temperature po…
The interaction between nanohydroxyapatite (HAP) and smooth muscle cells is an important step in vascular calcification. However, the effect of the shape of HAP on adhesion and endocytosis to aortic smooth muscle cells has been rarely reported. Four different morphological HAP crystals (H-Rod, H-Needle, H-Sphere, and…
Quasi-two-dimensional (2D) CdSe nanoplatelets (NPLs) are distinguished by their unique optical properties in comparison to classical semiconductor nanocrystals, such as extremely narrow emission line widths, reduced Auger recombination, and relatively high absorption cross sections. Inherent to their anisotropic 2D st…
Abstract Graphene is a promising material for sensing magnetic fields via the Hall effect due to its atomic-scale thickness, ultra-high carrier mobilities and low cost compared to conventional semiconductor sensors. Because of its Dirac band structure, graphene sensors differ from semiconductor sensors in that both el…
The discovery of superconducting and insulating states in magic angle twisted bilayer graphene (MATBG) has ignited considerable interest in understanding the nature of electronic interactions in this chemically pristine material system. The phenomenological similarity of the MATBG transport properties as a function of…
