Phase and structural behaviour in the NdAlO3-EuAlO3system has been studied in a whole concentration range. Depending on x two kinds of solid solutions Nd1−xEuxAlO3one with rhombohedral (x ≤ 0.15) and one with orthorhombic (x ≥ 0.25) symmetry exist at room temperature. A morphotropic phase transition occurs at x ≈ 0.20…
The poor thermo stability and electrical properties of insulation paper used in an oil-immersed transformer would limit the performance and size of the transformer. In order to substitute insulation paper, we chose polyphenylene sulfide (PPS) as the object of study to make research on its electro-thermal aging charact…
Nanostructured porous silicon templates (NPSiT) were prepared by photo-electrochemical anodization of p-type crystalline silicon in HF electrolyte at different current density. Five samples were prepared with current densities varied from 5 to 40 minutes at 30 minutes of etching time. The porosity and thickness were m…
The value of giant Raman scattering absolute cross-section for silver adatoms (σ ad = 3.1 × 10 −27 cm 2 /adatom) is determined by the measuring of the background intensity in the giant Raman scattering spectra at silver electrode surfaces in silver perchlorate solutions. With taking into consideration of the sulfate i…
Cover: The water dynamics near polystyrene thin films with different degrees of hydrophilicity are investigated. The orientational autocorrelation function of the vector associated with the water dipole is calculated in each layer of water of 0.125nm thickness from the interface into the bulk region. Further details c…
The bandwidth of the S-polarization and the P-polarization modes will separate while the narrowband thin-film filter is in oblique incidence, which will cause serious polarization dependent loss and limit its tunable range. The phenomenon of the polarization bandwidth separation and its relationship to the mirror laye…
Abstract. With the global environment worsening and the consciousness of protecting environment strengthening, the limitation of noxious gas from diesel engines is becoming more and more strictly. Selective catalytic reduction (SCR) aftertreatment system has been applied to reduce Nitrogen Oxides (NOx) as a key techno…
The electronic structures and magnetic properties of Pd-doped CdS have been studied by FLAPW method in the GGA. We find that the Pd-doped CdS becomes 100% spin polarized at fermi level when Pd substitutes for Cd atom both in 3×3×2 and 2×2×2 CdS supercells. The supercell magnetic moment reaches to 2.0μB. At the same ti…
Neural networks are applied to the long-term prediction of parameter variation. Regulation of the heat treatment of ferroconcrete is considered as an example. Experimental results are presented. An algorithm is proposed for planning the operation of the executive mechanism.
Effect of weak links destruction at the anisotropically shaped local surface regions of HTSC oxides on their remagnetization has been studied by angular dependences of the diamagnetic response.
Wes Nyborg was a pioneer in the field of biomedical ultrasound. In particular, Nyborg conducted extensive studies that provided insight into how bubbles oscillating in liquids generated forces that could alter the anatomy and/or physiology of cells. While these studies demonstrated that acoustic cavitation is instrume…
The results of investigations of pulse X-ray conductivity for metal-dielectric-metal and metal-dielectric-semiconductor-metal structures, where thin plates of Li2B4O7or Li6GdB3O9single crystals, and Li2B4O7glasses used as dielectrics, have been presented.
In this paper, a facile method was presented to fabricate CuS porous microspheres, which were formed by the intergrowth of CuS polycrystalline nanoslices. The obtained sample has been characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), selected area electronic diffraction (SAED), and scan…
The yellow luminescence (YL) band in unintentional doped n-GaN irradiated by 10 MeV electrons has been investigated by means of photoluminescence (PL) spectroscopy. The YL intensity increased after electron irradiation and thermal annealing, indicating that the deep level defects are created by electron irradiation an…
This paper reports on the Ag/HfO2/ZnO/TiAu Schottky structures, in which the semiconducting ZnO and HfO2layers are obtained using the low temperature Atomic Layer Deposition (ALD) method. Basing on the thermionic emission, differential and injection approaches an optimal thickness of HfO2capping layer for the ZnO-base…
Optical changes caused by60Co γ-irradiation are studied in glassy-like As2S3. The observed long-wave shift in the range of fundamental optical absorption edge accompanied by increase in transmittance is explained as a manifestation of complicated nature of radiation-induced structural transformations associated with c…
Colloidal semiconductor quantum dots (QDs) have been extensively explored for numerous applications ranging from optoelectronics to biotechnology. This strong demand for the colloidal QDs arises because of their favorable optical and electronic properties. From the application points of view, QDs typically need to be…
In this experiment, a new deposition technique was employed to deposit and to dope the amorphous carbon (a-C). Nitrogen doped amorphous carbon (a-C: N) thin films were prepared by Aerosol-assisted Chemical Vapor Deposition (AACVD) by varying the deposition time from 15 minutes to 60 minutes. The electrical and optical…
Simple doping process of Zinc (Zn) with Tin oxide (SnO2) was successfully prepared by the mechanochemical process, followed by a heat treatment and leaching. The raw materials are Tin Chloride (SnCl2) as a base element, Sodium Carbonate (Na2CO3) as an oxidizer and Sodium chloride (NaCl) as a diluent, while Zinc Chlori…
Hybrid photovoltaic concepts based on a nanoscale combination of organic and inorganic semiconductors are promising way to enhance the cost efficiency of solar cells through a better use of the solar spectrum, a higher ratio of interface-to-volume, and the flexible processability of polymers. In this work, two types o…
