This objective is to study the influence of pH on the electrochemical behavior of 00Cr15Ni7Mo2Cu2 supermartensitic stainless steel in 3.5% NaCl solutions using potentiondynamic polarization technique, open circuit potential tests and electrochemical impedance spectroscopy (EIS).The study reveals that the pitting poten…
Functional luminol derivative with cholesteryl substituted group has been designed and synthesized from the reaction of the corresponding precursor cholesteryl chloroformate with luminol. This compound can be spread on water surface to form stable monolayer. It has been found that UV and IR spectra confirmed the chara…
Metallic nanohole arrays and metallic nanodipole arrays are fabricated and experimentally characterized. A complementary response is observed in both transmission and reflection. For the metallic nanohole arrays, a peak (dip) in transmission (reflection) is observed at resonance whereas the metallic nanodipole arrays…
Bioresource utilization represents an important interdisciplinary research that integrates academic and industrial expertise across diverse scientific domains, including physics, chemistry, biology, and engineering. The present paper describes a cyber-infrastructure being created at the Brazilian Bioethanol Science an…
Compare to SAW (surface acoustic wave) device, APM (acoustic plate mode wave) device is more suitable for liquid sensing. In this paper, the theoretical model of APM device loaded with non-viscous liquid is built using the propagation characteristics of acoustic wave in laminated mediums. It's proved the influence of…
The main purpose of this paper is to underline the property of periodic structures consisting of layers with imaginary wavenumbers for ballistic electrons to allow charge carrier propagation in certain energy bands. Such periodic structures are analogous to composite optical metamaterials. In addition, we compare the…
In this article, Ni particles with different morphologies including spherical Ni and fibrous Ni particles had been synthesized by co-precipitation and e polyol methods, respectively‥ As such, a three-phase percolative composites containing Ni as the conductive phase with different morphologies, BaTiO3as the ceramic ph…
A thermal model developed in this paper provides a plausible explanation to the improved corona resistance performance of nanocomposites. The model calculates the localized temperatures for different filler concentrations. Lower localized temperatures are achieved even at low nanofiller concentrations due to well disp…
for the problem of the heterotopy particle during the Fe catalyst material manufacturing，the influence fact of hemorphology and size distribution of the catalyst is analyzed by cold numerical simulation and pilot test. It includes that the morphology of catalyst particle, the catalyst-synthesis recipe, solvent system…
In order to meet industrial safety standards in eccentric presses, the detent force caused by the reluctance change between permanent magnet (PM) and stator teeth of the acting high force tubular permanent magnet linear synchronous machines (PMLSM) should be reduced. The detent force is generated by two components: th…
Neutron total scattering measurements were performed at 300 K and 15 K to study local structural disorder in deuterium plasma treated and as-prepared Zn0.9Co0.1O nanocrystalline powder. We found that static disorder becomes a determining factor for atomic pair correlations on the length scale larger than r∼9Å. On the…
Natural Na-bentonites were modified with an organic chelating agent, sodium diethyldithiocarbamatre (DDTC), to prepare a new adsorbent (DDTC-bentonite) for mixed contaminant (Cu2+, Cd2+and phenol) removal. The optimal conditions for preparation the DDTC-bentonite were investigated. Moreover, the DDTC-bentonite showed…
A new unsymmetrical photochromic diarylethene, 1-(3,5-dimethyl-4-isoxazolyl)-2-[2-methyl-5-(4-formylphenyl)-3- thienyl]perfluorocyclopentene(1a) were synthesized, and its properties, such as photochromism and fluorescence properties, were investigated in detail. The results showed that this compound had good thermal s…
Conductive polymers presents a new and diverse range of chemical and electrochemical properties. These new properties have allowed their use in a wide range of applications such as electrical energy storage devices (e.g. supercapacitors). This paper presents a characterization of electrochemical behaviour of electro-a…
High Intensity Focused Ultrasound (HIFU) has gained considerable interest for clinical applications in recent decades due to its noninvasive characteristics. However current HIFU systems have limitations due to treatment times. Specifically it takes about two to three hours for the treatment of large tumors such as ut…
The authors investigated the mold electromagnetic stirring technology of horizontal continuous casting for CuCrZr alloys. Due to the oxidizability of the zirconium, the CuCrZr alloys are difficult to produce by continuous casting process. A short process for CuCrZr alloys material engineering is urgently needed. The m…
In this invited paper, we review some of our latest works on plasmonic antennas and their interactions with photonic angular momentum. As receiving antennas, both theoretical and experimental results reveal that spiral plasmonic antenna responds differently to photons with left-hand circular polarization and right-han…
High voltage properties of dielectric materials are of great interest for the insulator industrial field. Indeed, the application of alternative or continuous electrical field may modify the physical properties of polymers. Particularly, dipoles orientate themselves in the electrical field direction. So, macromolecula…
In the context of improving high voltage equipment recyclability, thermoplastic polymers like polyethylene terephtalate (PET) have become attractive candidates for replacing non-recyclable (thermosetting) insulators. In order to assess the suitability of PET for high voltage applications, its behavior under long term…
The weight loss measurements and potentiodynamic polarization techniques are used to assess the inhibitive and adsorption behaviour of 2-Benzothiazolethiol (BTT) for Q235 steel in hydrochloric acid solution. The inhibition efficiency is found to increase with increase in BTT concentration but decrease with rise in temp…
