In this paper, the effects of silver nano-spheroid size and elongation on plasmon wavelength are investigated, and the plasmon eigenvalues are formulated as a function of the radius and aspect ratio of the nano-particles. These can be used in eigenmode plasmonic interaction method to study interaction of nano-particle…
The performance of the polyphenylene sulfide fiber (PPS) was investigated by low temperature glow discharge plasma . The experimental results show that under the treatment of different plasma conditions, the PPS fiber surfaces appear the varying degree physics and chemical etching. It’s found that the friction coeffic…
A non-reciprocal metamaterial structure composed of a 2D periodic array of slot ring resonators including each a semiconductor-based isolator is introduced and experimentally shown to produce Faraday rotation. In contrast to previously reported non-reciprocal metastructures, which were of microstrip type and were limi…
A modification of chlorinated natural rubber via the ozonation process has been considered. Optimal regimes of ozonation are determined. It is shown that this modification makes it possible to increase the adhesion strength of vulcanized rubber by 10–40%.
Extra High Voltage and Ultra High Voltage porcelain solid core post insulators for use in up to 1200kV AC systems are being manufactured by various insulator manufacturers in India. One application is to use as bus support insulator in 1200kV substations. The post insulators shall have superior corona free performance…
Methods of mechanochemical treatment applied to eliminate the disadvantages of BiFeO 3 that impede its practical use are described. It is shown that the use of certain techniques for the mechanical activation of precursors allows us to enhance the structural and thermal stability of bismuth ferrite, to reduce its elec…
We Report Herein Results of an Investigation of the Assembly of Silver Nanoparticles Mediated by Glutathione (GSH) and Cysteine (Cys) Interaction in the Presence of Metal Ions: Ag+, Cd2+, Co2+, Cu2+, Fe3+, Hg2+, Ni2+, Pb2+, Zn2+. The Silver Nanoparticles Produce Well-Ordered Structures upon Interaction with Glutathion…
A design is presented for a beam-scanning Transformation Electromagnetics (TE) lens that allows an arbitrary number of beams at controlled magnitudes to be dynamically synthesized from a single omnidirectional source. A cylindrical slab of zero-index magnetic metamaterial controls the radiation pattern by altering the…
This paper involves designing and applying electric field analysis on multiple long rod insulators. Quality HV insulators are an integral part of power systems because they separate the Transmission lines carrying high voltages from the grounded poles. They must have the ability to withstand both high electrical and m…
We report the synthesis of pure and Mn doped ZnO in the form of nanosheets using a simple and single step procedure involving a microwave assisted chemical method. As prepared Mn-doped ZnO nanosheets were characterized using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission ele…
The far-infrared optical reflectivity of an optimally doped Ba 1− x K x Fe 2 As 2 ( x = 0.4) single crystal is measured from room temperature down to 4 K. We study the temperature dependence of the in-plane infrared-active phonon at 251 cm −1 . This phonon exhibits a symmetric line shape in the optical conductivity, s…
A ceramic insulator has an excellent anti-pollution performance, but sometimes flashover occurs on it and then the outage of power network follows. This paper analyzes the formation mechanism of flashover and the result is that the RMS of leakage current(LC) and discharge pulses reflect the contamination severity appr…
Thin films from the monolayer range to the thickness of 40 nm of the perfluorinated copper phthalocyanine (F 16 PcCu) were prepared by physical vapor deposition on freshly cleaved (001) faces of the alkali halides NaCl , KCl and KBr . The different lattice constants of the substrates provided sufficient difference to…
Cr(VI) has a highly toxic effect on the organism and has caused serious harm to the environment. Due to quantum size effects and interface coupling effects, mesoporous materials have novel physical, chemical and many other excellent performances, especially for the promising application in the adsorption of heavy meta…
Application of polymer as thickener of precursor solution for preparing boron nitride ( BN ) nanofibers by electrospinning brings carbon impurity in the nitride products. The control and removal of the carbon impurity are a key step in the synthesis of the BN nanofibers. In this article, the control and removal of the…
Static and dynamic hot spots limit the performance and reliability of electronic devices and ICs. We show that transient thermoreflectance imaging using a CCD camera can measure temperature distribution in chips with 0.1°C temperature, 100 nanosecond time, and submicron spatial resolution. It is possible to measure th…
The dynamics of the vapor-liquid interface when a solid particle heated to a high temperature comes into contact with a cold liquid is analyzed. The generalized Rayleigh-Lamb equation taking into account temperature changes in the liquid and the vapor, the saturation vapor pressure change associated with it, and the e…
When an ultrasonic wave with sound pressure less than the threshold level of bubble destruction irradiates microbubbles, the microbubbles aggregate by an acoustic radiation force and form bubble clouds. The cavitation of bubble clouds produces a large number of microhollows (microdips) on the flow channel wall. In thi…

A new method of calculating the spectral function of system-bath interaction during elementary biochemical reaction is proposed. This method was applied to the primary electron transfer in the photosynthetic reaction center of purple bacteria Rh. Sphaeroides. The calculated spectral functions differ significantly from…
