Culex quinquefasciatus cause severe biting nuisance and responsible for the spread of dreadful diseases among human beings. Biological researchers are trying to introduce eco-friendly products for the control of mosquitoes. The use of botanical pesticides has become very popular throughout the world as an alternative…
Styrene was obtained from Tianjin Damao Chemical Reagent Co. Ltd., was washed with 5 wt % NaOH solution and dried with Na2SO4 before use.
Pure and Y3+ substituted BiFeO3 (BFO) ceramics were synthesized by solid state reaction method. X-ray diffraction patterns of these samples have shown distorted rhombohedral structure with R3c space group symmetry. Photoluminescent spectra of pure BFO show blue emission corresponding to band-edge emission at 2.53 eV.…
This paper reports the X-Band (8-12GHz) and Ku-Band (13-18GHz) microwave transmittance and reflectance of polyanline thin films electropolymerised on stainless steel substrate. The waveguide reflectometer method has been used for the microwave studies. The polyanline thin film changes the transmission and reflection p…
While propagation of dislocations in body centered cubic metals at low temperature is understood in terms of elementary steps on {110} planes, slip traces correspond often with other crystallographic or non-crystallographic planes. In the past, characterization of slip was limited to post-mortem electron microscopy an…
Post processing of materials is necessary to suit them for the intended requirements. The properties of stainless steel of grade 316L cannot be influenced with further processing such as hot working [1]. Thus the current study aims at investigating the properties of stainless steel of grade 316L after being subjected…
Received August 27, 2012; Accepted December 19, 2012The main benefits of edible active coatings are to maintain the quality and extend shelf-life of fresh fruits and prevent microbial spoilage. Chitosan have a wide range of potential application in different fields of chemical sciences, biological systems, food scienc…
Functionalized and surface-modified gold nanorods (GNRs) have emerged as promising vehicles for the delivery of several therapeutic agents. Ease of functionalization, increased stability, biocompatibility, and size-dependent plasmonic properties make gold nanorods attractive in sensing, imaging, and delivery to differ…
The wedge cell of cholesteric liquid crystal device is designed and fabricated, and doping PM580 (exciton) in the cholesteric liquid crystal, the laser emission action is studied. There appear a series of parallel wedge edges of dislocation lines and different shapes of domain in the wedge cell. The planar state of al…
Photodynamic therapy(PDT) is a clinically approved procedure.Due to its minimal normal tissue toxicity,negligible side effects and high selectivity,it has emerged as an efficient treatment method for many kinds of cancers.Recently,significant effort has been devoted to enhance its selectivity and phototoxicity toward…
Drop weight setup was used to experimentally study the impact behavior of four tubular T-joints.The effects of impact energy(E),length-diameter ratio(α=L/D) and diameter of chord on the dynamic failure modes were obtained.The global and local buckling characteristics of tubular T-joints under impact loading were disco…
Scale samples generated by different cathodic current densities were characterized by scanning electron microscope and the X-ray diffraction method to analyze their surface morphology and polymorph composition.The results show that the electrochemical treatment would greatly change the scale morphologies and crystalli…
The reactivitys of toluene degradation were investigated at room temperature under atmospheric pressure by using a non- thermal plasma reactor loaded with SiO2,Al2O3 and NiO/Al2O3. The different reactivities on these catalysts may originate from their dielectric constant,toluene adsorption and ozone decomposition abil…
In order to study the combined damage of fragments and shock wave on helicopter rotor,we analyzed the rotor structure and equivalent,calculated the damage of helicopter rotor from the combination of fragments and shock wave using given fragments velocity and CONWEP explosion model.The result of rotor damage was compar…
As a kind of reactive power compensation equipment,magnetically controlled reactors(MCRs),based static var compensator,can be directly put into operation in 1 000 kV voltage level with control flexibility and high reliability.For this reason MCR is widely concerned and researched.However,low responding speed has alway…
Considering the varying capacities of polymer foam stabilizer under different environments,the well-performed AOS is selected as the foaming agent to study the effects of partially hydrolyzed polyacrylamide( HPAM),carboxymethyl cellulose( CMC), xanthan gum( XC) and other polymers on the stability of the foam surfactan…
The basic principles of zone melting technology are explained,its latest development and application are reviewed focusing on the progress of its critical process steps.Description is made of the current applications of zone melting in high-pure materials like semiconductors,refractory metals and rare earth elements.C…
The feasibility of preparing sodium borohydride by electrolyzing sodium metaborate has been demonstrated from the thermodynamic perspective and the cyclic voltammetry curves of different electrode materials were investigated. Furthermore, under the condition of copper as a working electrode, the changing relations bet…
SOFC (solid oxide fuel cell) is a very promising technology that achieves high power generation efficiency, while being very nearly usable. It is high time we considered enhancing commercialization and dissemination of SOFC by setting a standard for the evaluation method of SOFC cell/stack performance. In setting the…
