Orientational engineered (La, Mn) co-substituted BiFeO3 (LMBFO) thin films were epitaxially grown on CaRuO3 electroded (LaAlO3)0.3(Sr2AlTaO6)0.35 (LSAT) single crystal substrates by pulsed laser deposition. The experimental results demonstrate that the crystallographic orientation is the critical dominant of the struc…
A novel type of fast-neutron (energy E n >1 MeV) counter is presented. It is made of a fissionable natural-uranium foil faced to an intrinsic single-crystal diamond that detects the neutron-induced fission fragments escaping the uranium sheet. The fast response of the diamond is a key feature for its use at pulsed spa…
There is an increased study for considering the precise decisions on the design concept (DC) and material concurrently at the early stage of development of product. Inappropriate decisions on DC and material always lead to huge cost involvement and ultimately drive toward premature component or product failure. To ove…
In this article, the main principles of Forster resonance energy transfer (FRET) are described with special emphasis on luminescent lanthanide complexes (LLCs) in modern fluorescence spectroscopy and microscopy and their use in biomolecular analysis. The theoretical fundamentals of FRET are explained and the unique ph…
A guided-mode-resonance filter (GMRF) consisting of a thin film waveguide and a surface periodic relief has been widely studied for application to a laser mirror as well as to an optical wavelength filter, because of its great advantage in mass production in comparison to multilayer dielectric mirrors. However, GMRF n…
The properties of the cluster He(n)V, an iron vacancy with an increasing number of He atoms, is studied with molecular statics and molecular dynamics simulations. A study of the binding energy of the self-interstitial atom (SIA) and the He, shows that from n = 6 the He(n)V cluster is stable and cannot shrink anymore,…
Hydrogen plasma pretreatment is used to enforce the growth of vertically-aligned carbon nanotube forests on TiN substrates. The evolution of the substrate, catalyst, and nanotubes are studied by in situ and ex-situ photoemission and X-ray diffraction in order to understand the growth mechanism. We find that TiN retain…
Perceived moisture in shirt fabrics was determined using psychophysical methods and objectively measured moisture absorption behaviours. Four shirt fabrics were assessed: cotton; regular polyester; high-performance polyester; ahigh-performance polyester/polypropylene blend. After a screening test, six of 10 female sub…
We previously reported the construction of metagenomic libraries in the IncP cosmid vector pRK7813, enabling heterologous expression of these broad-host-range libraries in multiple bacterial hosts. Expressing these libraries in Sinorhizobium meliloti, we have successfully complemented associated phenotypes of polyhydr…
An approximate continuum theory is developed to effectively handle the problem of interaction between dislocations and inhomogeneity of any shape and properties. The inhomogeneity is, based on the Eshelby equivalent inclusion theory, equivalent to a homogenous one with a transformation strain. The interaction force be…
The properties of the majority trapped-hole centers in MgO, such as g -factors, positions of absorption and luminescence bands, and temperatures of thermal destruction, have been analyzed with the emphasis on the observed regular trends and interrelations between the properties of these centers. Particular emphasis ha…
Electrical conductivity of tetragonal β-phase (Bi2O3)1-x(Eu2O3)x (0.01 ≤ x ≤ 0.10 %mol) ceramic systems were investigated. The temperature and doping concentration dependences of the electrical conductivity were studied by four-point probe technique. The electrical conductivity increases with the increasing doping con…
In this Letter we propose a new phase diagram for the SmFeAs(O(1-x)F(x)) system, based on careful analysis of synchrotron powder diffraction data, SQUID, and muon spin rotation measurements. The tetragonal to orthorhombic structural transition is slightly affected by F content and is retained for the superconducting s…
Improvements in thermal interface materials (TIMs) can enhance heat transfer in electronics packages and reduce high temperatures. TIMs are generally composed of highly conductive particle fillers and a matrix that allows for good surface wetting and compliance of the material during application. Two types of TIMs are…
The ac conduction in ZnO nanorods has been investigated in the frequency range of 100 Hz−1 MHz and at various temperatures between 303 and 543 K. An agreement between experimental and theoretical results suggests that the ac conduction in ZnO nanorods can be successfully explained by Correlated Barrier Hopping model.…
ZnO nanowires doped with Mg have been successfully prepared on Au-coated Si (111) substrates using chemical vapor deposition method with a mixture of ZnO, Mg, and activated carbon powders as reactants at 850 C. The structural, compositional, morphological and optical properties of the samples were characterized by X-r…
PURPOSE: To determine the efficacy of sirolimus-eluting bioabsorbable magnesium alloy stents (SEBMAS) in restenosis prevention. METHODS: A balloon-expandable bioabsorbable magnesium alloy stent (BMAS) was created and coated with biodegradable poly(lactic acid-co-trimethylene carbonate) that contained the antiprolifera…
Abstract We have developed a technology for a new full‐color reflective electrochromic display ECD based on the subtractive color mixing model. This improves display brightness and color reproducibility. Additional advantage is simple production process. An active matrix driving of the full‐color reflective ECD has be…
A novel 3ω thermal conductivity measurement technique called metal-coated 3ω is introduced for use with liquids, gases, powders, and aerogels. This technique employs a micron-scale metal-coated glass fiber as a heater/thermometer that is suspended within the sample. Metal-coated 3ω exceeds alternate 3ω based fluid sen…
The intercalation of organic polymers molecules (i.e., PEGs and BRIJ) into a standard Ca-montmorillonite has been studied by XRD, TG, and IR spectroscopy. The polymer intercalation is confirmed by the increasing of the d(001) in XRD spectra as well as by the complex multisteps thermal decomposition behavior of the org…
