Iron oxide nanoparticles supported on zirconia were prepared by precipitation-deposition method and characterized by XRD, SEM, FT-IR, TGA/DTA, surface area and particle size analysis. Catalytic activities of the catalysts were tested in the gas-phase conversion of cyclohexanol in a fixed-bed flow type, Pyrex glass rea…
Surface selective patch binding (SPB) interaction occurring between two protein molecules, bovine serum albumin (BSA) and gelatin B (GB), both having same isoelectric pH (pI ≈ 5) and identical pH-zeta potential profile, was systematically examined. BSA : GB mixing ratio r was varied in the range 0.16–2.00 and ionic st…
A series of polycrystalline M-type hexagonal ferrites with the formula BaFe12-2xZnx NbxO19 (x = 0.2, 0.4, 0.6, 0.8 mol%) have been synthesized by the sol-gel method. The composition and microstructure govern the magnetic properties of ferrites. The XRD analysis shows the formation of pure magneto plumbite phase withou…
Enhancing the charge transfer process in nanocrystal sensitized solar cells is vital for the improvement of their performance. In this work we show a means of increasing photo-induced ultrafast charge transfer in successive ionic layer adsorption and reaction (SILAR) CdS-TiO2 nanocrystal heterojunctions using pulsed l…
The basic property of anti-smog masks is to block PM2.5 with excellent air permeability. A multi-layer nanofiber woven fabric with hierarchical structure is the best candidate for this purpose.
In this paper, the microstructure and dielectric properties of ion-doped La0.7Sr0.3MnO3 are investigated in detail. The polycrystalline ceramics of La0.7Sr0.3Mn1−yMyO3 (M = Fe, Ni, Cu; y = 0.3 or 0.5) are prepared by the sol–gel/sintering method. The symmetry of the crystal structure is improved and the dielectric pro…
:Didymosphenia geminata is a freshwater diatom that can form extensive nuisance mats in rivers and streams. First detected in New Zealand in 2004, D. geminata has been found in over 150 rivers throughout the South Island. The diatom exhibited interesting distribution patterns in New Zealand, where it has remained abse…
. Our results establish that the biocompatible miktoarm star ligand provides a useful platform to synthetically articulate the introduction of multiple functions onto GNS, and enhance their scope by combining their inherent imaging capabilities with efficient delivery and accumulation of active therapeutic agents.
We have prepared Ba6Fe25S27, and studied its magnetic properties and electronic structure. Single crystal diffraction revealed a cubic phase (Pm3[combining macron]m) with a = 10.2057(9) Å and Z = 1. Within the large cubic cell, tetrahedrally coordinated Fe atoms arrange into octonuclear Fe8(μ4-S)6(S8) clusters, which…
First-principle calculations were performed to investigate the structural, elastic, and electronic properties of iridium diboride (IrB <sub>2</sub> ).
It has been reported that titanium dioxide nanoparticles (TiO2 NPs) show toxicity in organs such as liver, lung, and intestine. There is, however, only a limited number of reports regarding the effect of TiO2 NPs on the male reproductive system. We examined the effect of TiO2 NPs on testicular function using mouse mod…
The 3107 cm-1 peak is observed in the infrared absorption spectra of all types of Ia diamonds, but it has not been observed in the iron-based catalyst. A series of nitrogen and hydrogen-doped diamond crystals is successfully synthesized using P3N5 as the nitrogen source in a catalyst-carbon system at a lower pressure…
Metal silver in the nanoscale range is widely used in the fields, such as microelectronics, optoelectronics, catalysis etc., due to its unique electrical and thermal conductivity, especially in nano-electrodes and nano-devices. Tensile deformation behavior of polycrystalline silver nanowires, in various grain size, is…
In this paper, molecular dynamics simulation was performed to predict the thermal conductivities of ordered mesoporous α-Al2O3. A kind of porous structure was proposed to guarantee the electrical neutrality. Based on the Matsui potential, the nonequilibrium molecular dynamics method adapted by Mller-Plathe was used to…
Dissolution and regeneration of bacterial cellulose (BC) extracted from nata de coco using different ratio of sodium hydroxide (NaOH) and urea as a solvent was investigated. The dissolution and structural properties of regenerated BC were determined by Fourier transform infrared spectrometric analyzer and X-ray diffra…
The copper selenide (Cu2Se)/polyaniline (PANI) nanocomposite was synthesized successfully by in situ polymerization through a simple and harmless technique. The structural characterization was carried out using Brucker D2 phase XRD. The optical measurements were made from UV-Visible spectrometer at normal incidence li…
P-type Ce-filled skutterudites Ce z Fe4−x Co x Sb12 (z = 0.3–1, x = 1–3) were prepared, and their thermoelectric properties were examined at temperatures between 500 K and 800 K. Specimens were synthesized by encapsulated melting at 1323 K for 10 h and were hot pressed after annealing at 873 K for 24 h. Stable skutter…
We have examined the growth kinetics of Fe-Zn intermetallics layers formed on Fe-1.5Mn (α-Fe single phase) and Fe-3.5Mn-0.1C (γ-Fe+α-Fe two phase) steel sheets dipped in pure Zn melt at 460 ºC. In an early stage of dipping, FeZn13-ζ phase layer is initially formed and its thickness slightly increases with increasing d…
The hydrotalcite-like compound [Mg2Al(OH)6]NO3·nH2O (shorted as MgAl–NO3) was intercalated with the chelating agent ethylenediaminetetraacetic acid (EDTA) and N,N′-1,2-ethanediylbis-1-aspartic acid (EDDS) by anion exchange to uptake heavy metal ions (Cu2+, Pb2+) from aqueous solutions. These layered double hydroxides…
