Understanding the fundamental properties of electrochemical systems, especially at the microscopic level, requires advanced tools combining electrochemical microscopy and scanning probe techniques with mathematical modeling for the quantification of the physicochemical characteristics of these environments. Comparison…
The paper deals with the three-phase three-wire shunt active power filter. The analysis of capacitor voltage in such compensator is presented. It is shown that fast component of the capacitor voltage is unavoidable. The slow component should be stabilized on the desired level. The results of SIMULINK computation for c…
The kinetics of osmium(VIII) catalyzed oxidation of antibiotic drug chloramphenicol by hexacyanoferrate(III) in aqueous alkaline medium was studied spectrophotometrically at 25°C. The reaction between chloramphenicol and hexacyanoferrate(III) in alkaline medium exhibits 1:2 stoichiometry (CHP:HCF(III)). The reaction i…
Zusammenfassung Aufgrund der Entwicklungen der Servopressen-Technologie in den letzten Jahren wird deren Einsatz für Unternehmen im Bereich der Kaltmassivumformung immer interessanter. Die Nutzung flexibel gestaltbarer Hubverläufe ermöglicht es dabei, gezielt auf den Umformprozess durch eine Variation der Umformgeschw…
Critical materials represent mostly metals having a big importance for the future of the economy in the European countries. It is very difficult to replace these critical metals by other metals. Because of their wide application, the demand for these metals is increased, but the production cannot follow their growing…
Summary: Some features of the instantaneous active and reactive powers p and q , not reported earlier, are discussed in this paper. It is shown that oscillating components and of these powers may not depend on the order of the load current harmonic. It was shown, moreover, that a load supplied with a nonsinusoidal vol…
通过实验模拟了10组氮、磷负荷对菹草(Potamogeton crispus)生长期和衰亡期茎叶附着物的影响.结果显示:随着水体氮、磷浓度的升高,菹草附着物的叶绿素a(Chl.a)含量、附着有机物量、附着无机物量和附着物总量均增加,在氮、磷浓度最高的T10组(总氮12.0 mg/L,总磷1.0 mg/L),附着物的总量达到高峰,附着物的Chl.a含量为2.005~4.765mg/g(DW),附着有机物的量为29.027~94.886 mg/g(DW),附着无机物的量为176.881~397.750 mg/g(DW),附着物总量为205.909~492.636 mg/g(DW).在菹草的快速生长期、稳定期和衰亡期,附着物的Chl.a…
Hierarchical structures of Li1+xV3O8 nanorods growing on electrospun fibers have been successfully synthesized by electrospinning and calcinations.Field-emission scanning electron microscopy, transmission electron microscopy, X-ray diffraction and Raman spectra are applied to characterize the products.The formation me…
This report covers papers published in 2012 dealing with the application of computational techniques to inorganic solids. It deals mainly with continuous solids that are ionic in nature; work on metals is excluded. Special attention is given to solids used in solid oxide fuel cells and batteries, solids with useful or…
The dramatic development of oil, electric power and transportation industries deteriorated alternating current(AC) interference of the pipelines. As a consequence, not only the corrosion of pipelines would be enhanced, but also the cathodic protection(CP) systems be affected significantly. The traditional CP criterion…
Cobalt tetra(2,4-dichloro-1,3,5-triazine)aminophthalocyanine(CoPc) was immobilized covalently on activated carbon fiber(ACF) felt to obtain CoPc-modified ACF(CoPc-ACF) catalyst, and an electrocatalytic oxidation system using CoPc-ACF as the anode was constructed. The electrocatalytic oxidation of Acid Red 1(AR1) was i…
and{223}components tend to be stable in subsequent cold rolling process.During annealing,on one hand,the development of∥ND texture is suppressed because finer MoC particles prevent the grain boundary migration.On the other hand,unfavorable texture{001}significantly reduces with Mo increasing,which is attributed to tha…

Physical characteristic and the Displacement Value of neomycin sulfate in suppository with various composition of PEG 400-4000 as it carrier has been studied. Displacement Value has been determined to adjust the weight of suppositories that varies due to the density difference among drug substance and its carriers. Th…
Структурно-энергетические изменения происходящие в нановолокнах упорядоченного сплава CuAu I с ГЦТ решеткой под действием одноосной деформации растяжения в направлениях <001> и <100> (<010>) были исследованы методом молекулярной динамики. Путем исследования поведения графика зависимости «запасенная энергия – время деф…
In this study, a spraying method was employed to coat nano-TiO2 particles on the surface of concrete surface layers. For comparison reasons, an intermixing method was also used to embed 5% nano-TiO2 particles in the testing samples. Photocatalytic degradation of NO was evaluated to compare their airpurifying efficienc…
Sweat is produced by the body naturally during physical activity and this fluid can be analysed in real-time to reflect the body’s hydration and electrolyte status. This paper reports a new type of organic disposable sensor pump that integrates sweat collection and sodium (Na+) ion sensing into cotton threads. This in…
To explore theoretically the sensitivity criterion and the mechanical properties of PETN explosive crystal,molecular dy- namics(MD)simulation periodic at 195,245,295,345,395 K for(4×3×4)super cells and its cutting model along(100)crystal- line surface was conducted by COMPASS force field in the NPT ensemble.The result…
An attractive type of nanofiller-carbon nanofiber(CNF) was used to modify high-density polyethylene(HDPE),in which the nanocomposites with 1%-20% CNFs were prepared via a two-step process including melt mixing and hot press.The crystallization and dielectric properties of CNF/HDPE composites,as well as the dispersion…
