A phosphorus (P)-doped n-type heteroepitaxial diamond (001) sample was grown in a DC-plasma chemical-vapor-deposition chamber. The crystalline properties of incorporated phosphorus were examined by cathode luminescence. Hall-effect measurement of the sample was performed for the temperature range of 293–870 K. The res…
We have synthesized sintered skutterudite CoSb 3 composed of large and small crystal grains. The sintered materials with larger crystal grains tend to show lower electrical resistivity, while those with smaller grains possess lower thermal conductivity. The possibility of enhancing thermoelectric performance by produc…
Heat transfer in a thermally positioned doubly clamped bridge is simulated to obtain a universal scaling for the behavior of microscale and nanoscale bridge structures over a range of dimensions, materials, ambient heat transfer conditions, and heat loads. The simulations use both free molecular and continuum models t…
The availability of intense and collimated synchrotron sources and fast-reading detectors, with the increased likelihood of severe radiation damage, has enabled and forced the community of protein crystallographers to acquire large numbers of datasets of a same structures in a relatively short interval of time. A simi…
In this study porous cell stacks for electrochemical flue gas purification were fabricated using tape casting and lamination followed by sintering. Two different mixtures of pore formers were used; either a mixture of two types of graphite or a mixture of graphite with polymethyl methacrylate micro-particles. It was s…
The corrosion behaviors of AA6061 alloy in ethylene glycol (EG)–water solution were investigated by weight‐loss test and electrochemical measurement. The surface morphology observation and composition analysis were performed by scanning electron microscopy (SEM) and energy dispersive X‐ray (EDX) spectroscopy. After we…
We report on the temperature dependence of the polarized photoluminescence (PL) exhibited by crystalline organic rubrene sheets with a thickness of \ensuremath{\sim}60 nm. To probe the correlations between the electronic states and the molecular stacking of rubrene molecules, the polarized PL spectrum of a single rubr…
We report on the magnetic properties of a Ni(2+)-vermiculite intercalation compound from Santa Olalla, Huelva (Spain). This modified vermiculite was studied by means of DC and AC magnetic measurements. The existence of two maxima in magnetic susceptibility below 10 K was interpreted in terms of the Cole-Cole formalism…
We report the hexagonal wurtzite crystalline structure of ZnO nanorod growth by hydrothermal chemical wet synthesis at low temperature (90°C). We have used p-Si (100), n-Si (100), α-quartz (0001), MgO (0001) and ITO (polycrystalline) substrates to understand the growth mechanism of ZnO nanorods with a low pressure env…
Spin-wave excitations revealed in the dynamically equilibrated one-dimensional superlattices formed due to phase separation and charge carrier self-organization in doped single crystals of Eu(0.8)Ce(0.2)Mn(2)O(5) and Tb(0.95)Bi(0.05)MnO(3) multiferroics are discussed. Similar excitations, but having lower intensities,…
Inducing the adsorption of oxygen on gold surfaces transforms the inert metal into a surprisingly reactive material, which acts as a highly selective, low-temperature catalyst. The strong interaction of atomic oxygen with Au greatly affects the surface morphology by increasing the number of undercoordinated Au atoms a…
Structure-property relations of monoclinic petalite, LiAlSi(4)O(10), were determined by experiment and atomistic modeling based on density functional theory. The elastic stiffness coefficients were measured between room temperature and 570 K using a combination of the plate-resonance technique and resonant ultrasound…
P-type nanocrystalline Bi 0.4 Sb 1.6 Te 3 thick films were directly deposited on copper substrates by aerosol deposition (AD) involving shock compaction of the starting powder at room temperature. The film deposition rate was over 700 μm/min. The relative density of the films was above 95%. Films with a thickness of o…
Abstract Coal rank (vitrinite reflectance) and clay mineralogy from the North Range Group of the Southland Syncline, and illite crystallinity in pumpellyite- and lawsonite-bearing terranes in the textural zone I of the Caples and Torlesse terranes were studied. Vitrinite reflectances range from 0.60 to 1.33% Rm oil (h…
Three glutamic acid derivatives, two boron-containing and one imide-containing compound, were synthesized and tested for antimicrobial activity targeting glutamate-racemase. Antimicrobial effect was evaluated over Bacillus spp. Docking analysis shown that the test compounds bind near the active site of racemase isofor…
We have studied oxidized porous silicon (OPS) properties using Fourier transform infraRed (FTIR) spectroscopy and capacitance–voltage C – V measurements. We report the first experimental determination of the optimum porosity allowing the elaboration of high-density OPS insulators. This is an important contribution to…
We report a refined and expanded synthetic study of 4,4-difluoro-1,3,5,7-tetramethyl-8-(aryl)-4-bora-3a,4a-diaza-s-indacene under treatment with POCl3/DMSO. The 2-chloro-6-methylsulfide derivative (Kim TI, Park S, Choi Y and Kim Y. Chem. Asian J. 2011; 6: 1358-61.) was one of five co-eluants, including 2,6-disulfido a…
Dynamic birefringence and viscoelasticity of a diblock copolymer micellar solution were measured in order to clarify the molecular origin of viscoelastic response of the macrolattice structure formed by micelles. The complex strain-optical ratio changed its sign with angular frequency ω and exhibited very complicated…
Mixed metal nitride (CaAlSiN 3 :Eu 2+ ) phosphor was synthesized from an appropriate mixture of CaCN 2 , CaCO 3 , AlN, Si 3 N 4 , Eu 2 O 3 and C by the carbothermal nitriding method in a N 2 gas flow: 1/2 CaCN 2 + 1/2(1-2 x )CaCO 3 + AlN + 1/3Si 3 N 4 + x Eu 2 O 3 + C → (Ca 1-x Eu x )AlSiN 3 + CO 2 ↑. The resultant ph…
The dissociative interaction of oxygen with structurally well-defined monolayer Pd(x)Ag(1-x)/Pd(111) surface alloys of different compositions, with well-known distributions of the respective surface atoms (A. K. Engstfeld et al., Phys. Chem. Chem. Phys. 2012, 14, 10754-10761), and the coadsorption of/reaction with CO…
