Lead sulfide (PbS) magic cubes were prepared by a simple hydrothermal method without any organic solvent. The product was characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM) and absorption spectrum. A solar cell, with a structure of Al/P3HT:PbS/PEDOT:PSS/ITO/Glass, was made. By a spin coating…
In this paper, we compared the difference between oxygen and sulfur adsorption on the InSb (110) surface by using first-principle calculations. The theoretical calculation results have demonstrated the advantages of sulfur adsorption, which provides a reasonable way for explaining the reason of selecting sulfur passiv…
The 2012 Users' Meeting of the Cornell High Energy Synchrotron Source (CHESS) convened June 5–6 at Cornell University, Ithaca, NY. CHESS director Sol Gruner opened the meeting welcoming 144 participants with updates on funding, projects, and accomplishments in X-ray research as well as X-ray and accelerator physicist…
In the presence of water ammonia solution the calcium bicarbonate converts into insoluble calcium carbonate. Linearly independent chemical reactions of calcium carbonate formation with application of ammoniac solution were defined by the Gram matrix. As a result of the thermodynamic analysis the probability of calcium…
This paper will report on the synthesization of varieties of nanostructured carbon nanotubes such as bundles of vertically alligned CNTs (VACNTs), spaghetti-like CNTs and spiral-like structure of CNTs (SCNTs) which are potentially useful in various application. Multiwall carbon nanotubes (MWCNTs) were produced from pa…
A novel polarization splitting is proposed through plasmonic-dielectric coupling with ultrashort coupling length. Extinction ratios of 20.8 dB and 17.0 dB for TE and TM polarizations are achieved at a coupling length of 4.13 μm.
We design integrated holographic filters with any transfer function by weakly modulating the top cladding of SOI waveguides. Our calculations are confirmed by full-vectorial simulations. Grating are fabricated with focused ion beam.
It is possible to carry out PD location using the time difference of PD pulses received by a UHF antenna array. In practical applications, the electromagnetic interference within the substation will pollute these received signals and make it difficult to calculate the time difference of the PD pulses, which, thus, red…
Experiment with electrostatic discharge(ESD) generator was implemented in two situations of gap state. All discussion in previous literatures on approach speed effect in electrostatic discharge is really the combination of contact mode discharge and air mode discharge because of final collision of electrode with the t…
An increased level of harmonics due to the proliferation of single-phase non-linear loads is raising serious concerns among utilities. Historically, passive filters have been proposed to reduce harmonics in MV utility applications. However, due to their limitations utilities are turning their attention to alternative…
This paper reports some aspects of major practical interest now that GaN HEMTs are in the onset of commercialization for high voltage applications (VB>; 300 V). The device reproducibility of 900 V-class MIS-HEMTs with a thin in-situ grown Si3N4gate insulator is investigated by means of wafer mapping and high-T stress.…
The experimental results concerning the correlation between morphological and electrical characteristics of a MWCNT/epoxy based composites are presented. The impact of a nanoclay filler is investigated on the DC conductivity of a matrix loaded with different concentrations of MWCNT in order to evaluate the improvement…
This paper analyzed the effects of the temperature and plasma on the nucleation and growth of the zinc oxide (ZnO) nanowires. Uniformly distributed ZnO nanowires were successfully synthesized through plasma-enhanced chemical vapor deposition (PECVD) on silicon (100) substrate under different thickness of gold (Au) as…
Abstract Unterschiedliche Fristen zur Neueinstufung und Kennzeichnung für Stoffe und Gemische bedeuten für Unternehmen mit hoher Produktvielfalt und komplexen Kundenstrukturen viel Mehrarbeit. Dabei ist wichtig, die Umstellungen sowohl intern als auch extern frühzeitig zu kommunizieren. Dann wissen Mitarbeiter wie Kun…

The crystal structure and magnetic properties of a system of Pr0.5Sr0.5Co1 − x Mn x O3 solid solutions were studied by neutron diffraction and magnetization measurements. It is shown that, at a low manganese concentration, the structure can be described by the I/2a monoclinic space group; with increasing substitution…
A new electrode coating slag system CaO-CaF2-BaO-TiO2-SiO2has been designed on the base of existing basic slag system. In view of uniform design method and computer program, the experiments were arranged. Nine to eleven coating composition were taken as independent variables (X1~ X11) which were divided into five leve…
Abstract Es gibt eine berühmte Zahlenfolge, die Fibonacci‐Reihe, bei der jedes Glied der Reihe aus der Summe der beiden vorangehenden Glieder gebildet wird. Die Zahlenreihe ist aber auch deshalb bemerkenswert, weil die Division der jeweiligen Glieder erstaunlicherweise stets sehr eng um den Wert 1,62 streut, ja mit au…
The cover picture shows the synthesis of ultrathin tin-doped zinc oxide nanowires by employing an aminolysis approach. The molecular mechanism of the reactions was identified by Fourier transform infrared (FTIR) spectroscopy. This finding suggests that the introduction of group IV dopants may serve as an effective str…
The main electrical, thermal and morphological properties of polymeric nano-sized composites of polyvinylidene fluoride (PVDF) modified by nanoparticles of Ni have been studied. Properties of nanocomposites can be improved at the optimal filler content compared to those for pure PVDF. For example, the beginning meltin…
