By Computer finite element analysis, the impact of the interface thickness, the interface module and the short fiber orientation of Al2O3-SiO2(sf)/AZ91D composite on the maximum fiber axial stress and the steady creep rate is studied. Maximum axial stress of the short fiber is in the fiber center, and the axial stress…
Using numerical simulation techniques, the response characteristics of metamaterials split-ring resonators (SRRs) in terahertz region are analyzed. We examine the transmission and dispersion characteristics of several SRRs and show that there are two significant resonances corresponding to electric response and magnet…
The structure of perovskite-type La0.95Sr0.05Ga0.95Mn0.05O3−xcrystals has been investigated using high-resolution X-ray powder diffraction technique in the temperature range of 298–1173 K. A phase transition from orthorhombic (Pbnm) to rhombohedral (R 3 c) has been detected near 340 K. A chevron-like configuration of…
The quick and precise locating of partial discharge is important in eliminating the hidden faults promptly and ensuring the safety and stability of the power system. In this paper, the existing methods of PD (Partial Discharge) locating were analyzed at first, and then a PD locating method based on ultra high frequenc…
Bone tissue engineering is important for the treatment of bone defects arising from bone damage associated with diseases, trauma, inflammation, tumour surgery and non-union bone repair following fr...
Abstract One-pot treatment of commercially available 1,3,3-tributoxy-2-cyanopropene with 2 equivalents of primary aromatic amines readily afforded 1,5-diaryl-1,5-diaza-3-cyanopenta-1,3-dienes. UV properties varied as steric size of the ortho-substituent in the N-aryl units increased. X-ray crystallographic analyses in…
A film solar cell was made with a structure of Glass/ITO/CdS/PbS/Al. CdS film was obtained by thermal evaporation. PbS film was prepared by a simple solid-solid reaction. The solar cells are photosensitive in a large spectral range (extending from near infrared to high energy side regions). The cell with the area of 0…
SBA-15 (Santa Barbara Amoprhous 15) was functionalized by using three different organosilane comprised of different functional group, namely 3-aminopropyltriethoxysilane (APTES), 3-mercaptopropyltriethoxysilane (MPTS) and triethoxyvinylsilane (TEVS). Materials were characterized by using X-ray Diffractor (XRD), Fourie…
In this presentation, the author discusses two recent results recently obtained by optical spectroscopy on solid state dispersions of SiNCs in an SiO2-matrix.
We are presenting the development of a nonlinear diffusion model to aid the design and fabrication of annealed proton-exchanged (APE) channel waveguides in zirconium-doped lithium niobate (Zr:LiNbO3or Zr:LN). This work follows research at Stanford by Bortz [1, 8] and Roussev [2], who developed nonlinear diffusion mode…
Theoretical study of influence of electron-electron scattering on spin relaxation length in single layer graphene (SLG) and bilayer graphene (BLG) is done using ensemble semi classical Monte Carlo simulation. The comparison is made by including electron-electron interactions with electron-phonon interactions (acoustic…
Ordered microporous carbon materials with controlled chemical and physical properties were synthesized by one-step nanocasting process using different carbon precursors. Large amount of heteroatoms, particularly oxygen and nitrogen species were presented in the carbon matrix. The interactions between the electrolyte i…
The serotonin transporter (SERT) is exported from the ER by recruiting SEC24C to its C-terminus [ 1 ]. The same region also provides a docking site for proteinaceous chaperones (HSP isoforms) that assist in folding [ 2 ]. Based on these observations, we postulate sequential exchange of the chaperone(s) for the COPII c…
Unusual enhancement of mid-infrared light emission from CdTe/PbTe heterostructures is observed. It is discovered that the observed intense mid-infrared luminescence in the structures comes from the inherent polar interface character and coupling of surface plasmons localized at the metallic CdTe/PbTe interface to ligh…
P-type silicon wafer (; orientation; boron doping; 0.75 ~ 10 Ωcm-1) was used to prepare samples of porous silicon nanostructures. All the samples have been prepared by using photo-electrochemical anodization. A fixed etching time of 30 minutes and volume ratio of electrolyte, hydrofluoric acid 48% (HF48%) and absolute…
Ferroresonance over-voltage is one of the most important factors to impact the inner insulation of electrical appliances. The damage to appliance caused by ferroresonance over-voltage accounted for a great majority proportion in power system. A criterion in neutral-ungrounded power system was deducted in detail to est…

Overheat fault is the main type of the insulating faults in gas-insulated apparatus, which can produce various decomposition by-products. This paper presents the relationship between the decomposition by-products and the severity of overheat fault, by carrying out a series of overheat experiments. The various experime…
Ionic interpolymeric complexes of polyoctamethyleneacetamidine with polyethers terminally modifi ed with 4-[5-(4-hydroxyphenyl)-3-oxopenta-1,4-dienyl]benzoyl (chromophore) groups were prepared. The complexes exhibit third-order nonlinear optical properties. Factors affecting the third-harmonic generation effi ciency w…
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…
