This work proposes a calibration method to determine the complex permittivity of materials based on the cavity-perturbation method. The method can characterize a sample with relative large in volume or high in dielectric constant, which significantly broadens the scope of the conventional perturbation method. The theo…
Solution-processing of chalcogenide glass materials has attracted attention for the fabrication of photonic devices. We have carried out linear and nonlinear optical studies on Ga9Ge27Se64 nanocolloidal solutions with varying concentrations and witnessed the opportunity for engineering the optical properties of the ma…
Recoverin, a member of the neuronal calcium sensor (NCS) branch of the calmodulin superfamily, is expressed in retinal photoreceptor cells and serves as a calcium sensor in vision. Ca²⁺-induced conformational changes in recoverin cause extrusion of its covalently attached myristate (termed Ca²⁺-myristoyl switch) that…
This article reports the development of a systematic methodology for the evaluation of gas-phase filtration models. In this approach, two sets of experiments are performed. For the first, all of the required model input parameters are quantified either experimentally or empirically. The second set of experiments is ne…
Artemisinin form the most important class of antimalarial agents currently available, and is a unique sesquiterpene peroxide occurring as a constituent of Artemisia annua. Artemisinin is effectively used in the treatment of drug-resistant Plasmodium falciparum and because of its rapid clearance of cerebral malaria, ma…
This paper presents a review of harvesting green energy from road. There are three forms of green energy exist in road: light, thermal and mechanical energy. Photovoltaic technology, thermoelectric technology, directly heat transferring and piezoelectric technology are discussed in this paper, as well as the cases stu…
We report a facile strategy to synthesize the nanocomposite of Co3O4 nanoparticles anchored on conducting graphene as an advanced anode material for high-performance lithium-ion batteries. The nanocomposite was characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron spectros…
Large areas of Plinthosols with ferruginous materials such as plinthite and/or petroplinthite are fairly common in the Brazilian Amazon basin. This work was carried out to investigate the chemical behavior, mineralogical composition and weathering stage of four representative soil profiles with plinthite and petroplin…
With the popularization and development of science and technology, especially in the field of high speed machine tool, the compressor and the micro gas turbine system, the traditional motor can't fit these requirements. Because of its high speed,supreme power density and obvious efficiency advantages, high speed perma…
Article Spruce glucomannan: Preparation, structural characteristics and basic film forming ability was published on August 1, 2013 in the journal Nordic Pulp & Paper Research Journal (volume 28, issue 3).
A novel approach of photo-triggered redox frontal polymerization (FP) by integrating photocaged superbase (QA-DBU) with a peroxide initiator (dibenzoyl peroxide, BPO) is presented for the synthesis of thermally sensitive materials. Under photo-irradiation at a localized region, the regenerated superbase can diffuse in…
This article presents a model of the electrohydrodynamic fields that occur inside an axisymmetric electrostatic precipitator of the wire/cylinder type under laminar flow conditions. Five relevant dimensionless numbers were identified. Besides two geometrical parameters, these numbers include the electric Reynolds numb…
Finite element (FE) simulations of the welding of two high grade steel pipes are described. The first is a P91 steel pipe welded with a similar P91 weld consumable, and the second is a P92 steel pipe welded with dissimilar nickel–chromium based weld consumables. Both welds are multipass circumferential butt welds, hav…
Ferric vanadate (FeVO4) nanoparticles as visible-light photocatalysts were successfully prepared by microwave irradiation method. The structure and morphology of FeVO4 nanoparticles were charactered by X-ray diffraction (XRD) and scanning electron microscope (SEM). Absorption ranges, which are responsible for the obse…
The aim of this paper is to investigate the rheological properties of Multi-Walled Carbon NanoTube (MWCNT) enhanced bitumen. The rheological properties of bitumen samples with a range of MWCNT applications are evaluated. The shear complex modulus of the samples increased after ageing, and also increased as the percent…
The impact of high energy electrons in multi-layered shielding structures has been measured in terms of dose enhancement effects. New dosimetric data from a series of extensive experimental tests have been obtained and compared to the latest electromagnetic physics models included in the Geant4 Monte Carlo toolkit.
Evidence for high-Tc cuprate superconductivity is found in a region of the phase diagram where non-superconducting Fermi liquid metals are expected. Cu valences estimated independently from both x-ray absorption near-edge spectroscopy and bond valence sum measurements are >2.3, and are in close agreement with each oth…
Summary A range of crystalline copolymers of ethylene with α‐olefins (propene, hexene, octene and octadecene) were prepared using the complexes Et(Ind)2ZrCl2 and (nBuCp)2ZrCl2 activated with MAO. The average composition of the copolymers was measured using 1H‐ and 13C‐NMR. Then the samples were characterized by High T…
We report a single-crystal study on the Kondo semiconductor CeFe 2 Al 10 in which we measured the magnetic susceptibility, electrical resistivity, thermopower and thermal conductivity. The highly anisotropic behavior in all measurements indicates an anisotropic electronic structure that could originate from a c – f hy…
High-temperature oxygen permeability measurements had determined grain-boundary diffusivities (deltaD(sub gb)) in bulk polycrystalline alumina (Wada, Matsudaira, and Kitaoka). They predict that oxygen deltaD(sub gb,O) varies with oxygen pressure as P(O2)(sup -1/6) at low pressure whereas aluminum deltaD(sub gb),Al var…
