Compared with self-assembly of molecular building blocks or template printing et al. methods, coaxial electrospinning can be used to prepare various organic or inorganic tubular nanostructures fast and facilely. With better controlling, coaxial electrospinning can realize diversification and encapsulation of nanofiber…
injection of iodinated radiographic contrast media is generally safe, however with increased use adverse events are more likely to occur. The most important adverse effects include hypersensitivity reactions, contrast-induced nephropathy and thyrotoxicosis. There is no protocol that will prevent non-ige-mediated anaph…
Partial discharge (PD) monitoring has been the subject of significant research in recent years, which has given rise to a range of well-established PD detection and measurement techniques, such as acoustic and RF, on which condition monitoring systems for highvoltage equipment have been based. This paper presents a no…
AIMS: Cationic liposomes have been shown to preferentially target the tumor vasculature, but not uniformly. Bevacizumab antibody selectively accumulates in tumors expressing VEGF. We thus developed bevacizumab-modified, pegylated cationic liposomes (PCLs) to improve the distribution of liposomes along tumor vessels, a…
Monolayer membranes of conjugated carbon represent a class of nanomaterial with demonstrated uses in various areas of electronics, ranging from transparent, flexible, and stretchable thin film conductors, to semiconducting materials in moderate and high-performance field-effect transistors. Although graphene represent…
Abstract Polysulfone (PSF) and sulfonated polysulfone (SPSF) were synthesized and characterized by IR spectrum. Sm 1.5 Sr 0.5 NiO 4 (SSN) and Ni‐Ce 0.8 Sm 0.2 O 2− δ (Ni‐SDC, Ni‐samarium doped ceria) were prepared and characterized by X‐ray diffraction (XRD) and scanning electron microscopy (SEM). Ammonia was synthesi…
In a rabbit model we investigated the efficacy of a silk fibroin/hydroxyapatite (SF/HA) composite on the repair of a segmental bone defect. Four types of porous SF/HA composites (SF/HA-1, SF/HA-2, SF/HA-3, SF/HA-4) with different material ratios, pore sizes, porosity and additives were implanted subcutaneously into Sp…
Magnetic fringe fields emanating from a multiferroic heterostructure composite of Terfenol-D and lead magnesium niobate-lead titanate were utilized to actively tune a meander line microstrip ferrite phase shifter operating above ferrimagnetic resonance at C-band. Differential phase shifts of 65° were measured when tun…
To understand the basic material properties required in selecting a metallic interlayer for enhanced adhesion of diamond coatings on the substrates, the interfaces between diamond and metals with different carbide formation enthalpies (Cu, Ti, and Al) are studied using density functional theory. It is found that the w…
Critical photonic, electronic, and magnetic applications of two-dimensional nanocrystal superlattices often require nanostructures in perfect single-crystal phases with long-range order and limited defects. Here we discovered a crystalline phase with quasi-long-range positional order for two-dimensional nanocrystal su…
The adsorption of atoms and molecules on single crystal surfaces allows one to produce well-characterized atomic, molecular, or dissociated adsorbates. Microcalorimetric measurement of the resulting adsorption energies, i.e., single crystal adsorption calorimetry, allows determination of the standard enthalpies of for…
Corrosion initiation on steel from predeposited NaCl particles was observed in situ using an optical microscope. Corrosion did not initiate from small droplets (D<&sim45 μm) formed by the deliquescence of predeposited NaCl particles upon exposing to high humidity (RH>80%). Corrosion occurred under larger NaCl droplets…
Flake-shaped FeCuNbSiB particles were fabricated by ball milling the annealed ribbons. The composites of flake particles/paraffin wax were prepared with and without rotational orientation in an applied magnetic field. The complex permeability of the composites was measured in the frequency range of 0.1–18 GHz. The ori…
FeSe 0.5 Te 0.5 thin films with a PbO-type structure are successfully grown on MgO(100) and LaSrAlO 4 (001) substrates from FeSe 0.5 Te 0.5 or FeSe 0.5 Te 0.75 polycrystalline targets by pulsed laser deposition. The film deposited on the MgO substrate (film thickness: ∼55 nm) shows superconductivity at 10.6 K (onset)…
Solid solutions among zircon (ZrSiO 4 , I4 1 /amd) and zircon-structured orthosilicates ASiO 4 (A = Hf, Th, U, Pu, or Ce) are important to a wide variety of applications: nuclear materials, geochronology, and even electronic materials. The thermodynamic mixing properties of the following seven binary solid solutions w…
The coordination of Mn in doped SrTiO3 ceramics having nominal compositions SrTi0.98Mn0.02O3 and Sr0.98Mn0.02TiO3 was analyzed using x-ray absorption fine structure (XAFS) measurements. As expected, Mn4+ substitution for Ti4+ leads to Mn occupancy of the octahedral B-sites of ABO3 perovskite lattice with a Mn–O bond d…
This work presents measurements of the partial discharge (PD) extinction voltage in three different types of test objects, using semi-square voltages with 2 ¿s and 100 ¿s rise time. A needle creating corona discharges, a twisted pair specimen commonly used for testing motor insulation and a paper/oil test object model…
Partial Discharge (PD) diagnosis is a recognized technique to detect defects within high voltage insulation in power system equipment. A variety of methods exist to capture the signals that are emitted during PD, and this paper focuses on the ultra high frequency (UHF) and IEC 60270 techniques. Phase-resolved patterns…
A high-temperature solid-state reaction technique was used to prepare the polycrystalline samples of cerium (Ce) modified lead zirconate titanate with Zr/Ti ratio 65:35 (i.e., Pb(Zr0.65-xCexTi0.35)O3(PZCT)). Preliminary X-ray structural analysis exhibits the formation of the new compositions of PZT. In order to study…
Epoxy-based nanocomposites (NCs) were prepared using clay modified by either primary amine or tertiary amine, and the effect of the difference in modifier on the thermal and dielectric properties of the NCs were discussed. The NC with clay fillers modified by the primary amine, 1C, shows a glass transition end tempera…
