Municipal solid waste incinerator fly ash (MSWIFA) is considered a hazardous material because of its high content and leachability of heavy metals and soluble salts. In this study, leaching and thermal mobility of four selected heavy metals (Pb, Zn, Cu, and Cd) found in two types of MSWIFA [cyclone ash (CA) and filter…
Cassettes harboring luciferase reporter driven by Bombyx mori cytoplasmic actin gene promoter (A3) (671 bp) and B. mori nuclear polyhedrosis virus immediate-early promoter (IE-1) (580 bp) were transferred to the bacmid AcDeltaEGT to generate the recombinant Autographa californica nuclear polyhedrosis viruses, AcNPVA3L…
Zr,Pr-codoped and Si,Pr-codoped single crystals were grown from the melt by the micro-pulling-down method. The effect of Zr/Si-codoping on YAIO3:Pr scintillation properties, such as radioluminescence, scintillation light yield and decay time, was investigated. Absorption spectra of as-grown and air-annealed samples re…
This work is devoted to the development of a new model (based on the molecular-statics method) for studying the diffusion properties of point defects in metals. In the model, a new algorithm is realized, which makes it possible in a self-consistent manner to calculate the atomic structure in the vicinity of a defect a…
A new polymorph of CuMoO4, ε-CuMoO4, has been synthesized and characterized. The material exhibits a three-dimensional structure with tetramers of edge-shared Cu2+O5 square pyramids that link to the Mo6+O4 tetrahedra. Magnetic susceptibility measurements indicate that the material orders magnetically, with a ferromagn…
Abstract A principal concern with alumina‐forming coatings for high‐temperature oxidation protection and bond coats (BCs) for ceramic thermal barrier coatings (TBCs) used in gas turbines is the spalling of the alumina scales during service. This paper describes the effects of BC surface preparation on the durability o…
A castable, low melting temperature glass-ceramic system (30% Bi2O3, 30% Nb2O5, 30% B2O3and 10% SiO2, in mol%) suitable for microwave applications is fabricated and characterized. Depending on heat treatment temperature, the glass ceramic exhibits permittivity, 15 ≤ εr≤ 41, temperature coefficient of resonant frequenc…
[(en)Pt(-OH)2Pt(en)]2+, a dinuclear -hydroxo bridged complex (with en = ethylenediamine) crystallizes with excess AgNO3 in high yield as the trinuclear complex [{(en)Pt(-OH)2Pt(en)}Ag](NO3)3 (Pt2Ag, 1) from water. The two halves of the complex are significantly bent (dihedral angle 42.2°) and the three metals form a t…
We report the results of an investigation of ion-beam-induced deposition (IBID) mechanisms in terms of secondary atoms, secondary electrons, and primary ions. Comparison of the volume of a deposited box with that of the material deposited onto a nearby sidewall shows the significant contribution of secondary particles…
This paper proposes and demonstrates a novel microcalorimetric sensor for detecting Neisseria meningitidis. To eliminate additional heating structures and calibration steps, a split-flow microchannel is integrated into the microcalorimeter. The split-flow microchannel constantly maintains the output of the microcalori…
Essential enhancement of light emission ability of europium molybdate - Eu2(MoO4)3(EMO) crystals has been achieved by combined application of high pressure (9 GPa) and heat treatment (a procedure was repeated from 3 to 25 times for different samples). Multifold increase in light emission of EMO single crystals can be…
To study the tribological performance of metal-on-metal hip joint resurfacings, the wear performance of three pairs of Co-Cr-Mo alloy samples (pins and plates) were tested in a multidirectional pin-on-plate wear machine. An 'as-cast', a single-heat-treated, and a double-heat-treated set of specimens were tested to 3 x…
During the last decades, limnological studies on Chilean systems have contributed to know the species composition and main environmental variables of many water bodies distributed over a wide latitudinal interval, from 18º to 53º S.However, we still lack of a comprehensive view about the structure and functioning of r…
Two cyanobacterial strains, Pseudanabaena sp. 0411 and Synechococcus sp. 0431, were isolated from a sample collected in the Kotel'nikovskii hot spring of the Baikal rift. According to the results of light and transmission electron microscopy, as well as of the phylogenetic analysis of the 16S rRNA gene, these cyanobac…
An extreme ultraviolet (EUV) interference lithography beamline using a single grating has been constructed at the BL3 beamline in the NewSUBARU synchrotron radiation facility. Using a single grating, a 400-nm line and space (L&S) resist pattern was replicated on a wafer by single grating interferometric lithography sy…
In this paper, the three-phase four-wire active power filter based on a three-level neutral-point-clamped inverter is presented. The proposed active power filter and controller eliminate harmonics in all three phases as well as the neutral current. The existing neutral-point-clamped inverter for a three-phase three-wi…
The earth faces environmental problems such as temperature increase and energy crisis. One of the solutions for the problems may be to put hydrogen energy to practical use. Superconducting devices for power applications are promising technologies for saving energy. By convergence of high temperature superconductors (H…
The fixed-bed adsorption process has been studied as one of the promising processes for the recovery of tritiated water in the field of nuclear fusion. The influence of the framework SiO2/Al2O3 ratio ranging from 2.0 to 10.0 on the tritiated water adsorption and desorption characteristics in the H2O-HTO binary systems…
A impregnação a vácuo (IV) tem sido estudada como uma alternativa para reduzir o tempo dos processos de salga aplicados a diversos alimentos. Neste trabalho, foi investigada a influência da aplicação de vácuo no processo de salga de cortes de peito de frango. Os cortes foram submersos em soluções com diferentes concen…
In this study, a new approach to a UV-blocking treatment for cotton fabrics was developed by dyeing and finishing in one bath and two steps. In this approach, nano-TiO 2 was used as inorganic anti-ultraviolet agent, adhesives poly (vinyl pyrrolidone) PVP was used to improve the wet fastness. Ultraviolet Spectrometer w…
