Experiments were conducted to investigate the decolorization of methyl orange simulated wastewater in order to assess the effectiveness and feasibility of ultrasound(US) enhanced high-purity chlorine dioxide(ClO2) oxidation process. The results showed that in ClO2/US system the decolorization rate of methyl orange was…
To prevent the silica scale formation in the geothermal water recycling process, the silicic acid perfectly removed from geothermal water as calcium silicate by calcium nitrate. Ordered mesoporous silica was synthesized at strong acidic condition by using low cost calcium silicate as silicon source, which was separate…
In this contribution, the simultaneous and switchable laser operation is reported at 523 nm and 640 nm. A dual wavelength laser operation at 607 nm and 640 nm of Pr:YLF was previously obtained by the use of intracavity prisms.
The dielectric properties of solid solutions based on sodium potassium and sodium lithium niobates have been studied in wide ranges of temperatures (25–750°C), frequencies (25 to 10 6 Hz), and electric fields (up to 30 kV/cm). We have identified solid-solution regions differing in the temperature and frequency depende…
The method of deposition from solutions was used to synthesize [RhL 4Cl2]HSO4 · nH2SO4 · mH2O complex salts (L = Py, γ-picoline), n ≈ 0.5−0.6, m ≈ 5−6. According to the data of X-ray phase analysis, the crystal structure of these salts is formed by layers of cations separated by layers consisting of anions molecules o…
According to the desulphurization reaction temperature and the content of calcium sulfite, FGD ash is simulated, that is the ordinary fly ash mixed with different weight percentage of CaSO3·1/2H2O is followed by drying at 100°C. And then by the experiment of workability, strength, sulfate resistance and rebar corrosio…
^{75}As and ^{139}La NMR and nuclear quadrupole resonance (NQR) studies on Zn-substituted LaFeAsO_{0.85} have been performed to microscopically investigate the Zn-impurity effects. Although superconductivity in LaFeAsO_{0.85} disappears by 3% Zn substitution, we found that NMR/NQR spectra and NMR physical quantities i…
Transversal magnetoresistance is calculated for numerous metal cases on the basis of simple electron theory. Any metal can be represented by a single band of states having a closed Fermi surface which is assumed to be similar in shape to a sphere. In an external electromagnetic field the electron transport seems to be…
The authors performed a detailed spectroscopic investigation varying both excitation energies and intensities to test these models. Graphene photoluminescence is found to be very broad ranging from 600 to 1200 nm. While the authors observe different photoluminescence spectra at different excitation energies no pronoun…
Eight bioactive drug compounds (abamectin, amoxicillin, dexamethasone, dexamethasone valerate, ketoprofen, melatonin, oestradiol 17β, and oestradiol benzoate) were combined via melt extrusion and disc pressing processes with a polycaprolactone (PCL) matrix and were then evaluated and compared via membrane diffusion an…
Magnetization and magnetic susceptibility measured in the zero-field-cooled mode were used to study the spin crossover transition in polycrystalline Cu x Co y Cr z Se 4 compounds.With increasing Co content a transition from ferromagnetic order via ferrimagnetic one to antiferromagnetic-like behaviour was observed.This…
We present a study of the neutral exciton and negative trion recombination spectra of an individual CdTe quantum dot with a single manganese ion, in magnetic field measured in the Voigt configuration. We describe experimental results and compare with a theoretical model. The quantitative agreement between the model an…
The as-cast microstructures of high carbon high speed steels (HC-HSS) made by sand casting, centrifugal casting and electromagnetic centrifugal casting, respectively, were studied by using of optical microscopy (OM) and D/max2200pc X-ray diffraction. The results show that the microstructure of as-cast HC-HSS is domina…
The work deals with evaluation of joint of stainless steel 304 SS (sheet) and commercially pure Ti both after welding explosion and followed-up annealing at 600°C/1.5h/air. The bonding line shows sinusoidal character with curls in crest unlike the trough of the sine curve. The heat treatment does not change the charac…
The solidified structure of the thin-walled and complicated Ti-6Al-4V castings produced by the vertical centrifugal casting process was studied in the present work. The results show that the wall thickness of the section is featured with homogeneously distributed fine equiaxial grains, compared with the microstructure…

Features of the porous ceramics polarization based on the previously developed theory are described. The numerical study of the field remanent polarization depending on the porosity percentage in ACELAN finite element package is presented. The research results are used to model the problem of determining the piezoelec…
We report on how to determine asymmetrical director distribution throughout a liquid crystal layer such as a bistable hybrid-twisted nematic (BHTN) liquid crystal device by means of renormalized transmission spectroscopic ellipsometry. The advantage of the plural oblique incidence spectroscopic ellipsometry (POISE) is…
Abstract Protoglobin from Methanosarcina acetivorans C2A (MaPgb), a strictly anaerobic methanogenic Archaea, displays peculiar structural and functional properties within members of the hemoglobin superfamily. In fact, MaPgb‐specific loops and a N‐terminal extension (20 amino acid residues) completely bury the heme wi…
