In this paper, effects of dividing the air-gap in the iron-core of shunt reactors into several discrete gaps on inductance parameters of the equivalent circuit, core losses and gap losses are investigated. This is achieved by both analytical calculations and Finite Element Method based analyses. A new method called Mo…
Abstract In the past several years there has been increasing interest in dispersion methods using ultrasound power for minute particles, such as cosmetics, medicine, catalyst, pigments, toner and ink. However, for nano-sized particles, the conventional ultrasound homogenizer, which is using a Langev...
Antimicrobial PhotoDynamic Therapy (APDT) represents a very promising strategy, particularly for the treatment of localized infectious diseases.[1] PDT involves the use of a non-toxic photosensitizer (PS), f. i. porphyrins, phthalocyanines, in combination with harmless visible light of appropriate wavelength to excite…
The many requirements for a material to perform effectively as a protective coating for stone can only be met by polymers consisting of properly designed multifunctional macromolecules. Multicomponent fluorinated acrylic-based copolymers were produced by free radical polymerization\nof monomers bearing different funct…
Quantum dots (QDs)-based solar cells have received great attention as a cost-effective and highly efficient alternative to conventional solar cells. In addition, QDs are considered to have potential for opening a new way to utilize hot photogenerated carriers or for generating multiple charge carriers with a single ph…
Plasmons, which are collective excitations of charge carriers, have been extensively studied on account of their importance in condensed matter physics and their potential application in the fabrication of enhanced, highly efficient nanoscale devices. With the advance in technology, plasmons could eventually be confin…
We have measured two-dimensional (2D) rescattering photoelectron momentum spectra of randomly oriented N2 and O2 molecules generated by near-infrared ultra-short laser pulses and have extracted corresponding elastic differential cross sections (DCSs) of free electrons scattered by the target ions. The comparison of th…
As an immune-privileged site, the brain represents a particularly challenging area when it comes to controlling infection and inflammation. Toxoplasma gondii provides us with a model of a chronic infection in the CNS that represents an efficient and balanced response from the healthy immune system. The effector functi…
The monograph contains publications submitted to the 10th Joint International Scientific Conference CLOTECH 2012 on 'Innovative materials & technologies in made-up textile articles, protective clothing and footwear'
La consecuencia de patrones nanoscopicos funcionales regulares y el control de estructuras superficies a la escala manometrica son esenciales para el desarrollo de superficies con propiedades nuevas y utiles.
Ultrafast photoelectron imaging spectroscopy enables observation of three-dimensional k-vector distribution upon photoionization from non-stationary rovibronic states of a photoexcited molecule. The time-energy mapping of photoelectron angular distribution uncovers ultrafast non-adiabatic electronic transitions throug…
柜式气体绝缘开关设备（cubicle gas insulated switchgear，C-GIS）由其全可靠性能高、小型化等特点在电力系统中得到广泛的应用。但由于C—GIS开关柜的主要绝缘介质sF6气体具有较强的温室效应，且其成本较高，迫切需要减少或不用SF6气体。针对C—GIS开关柜较低的气压条件，探讨sR混合气体替代sR的可行性。采用圆形平板电极模拟均匀场，研究均匀场、较低气压（0．1～0．25MPa）下SR与N2、CO2两种气体的二元混合气体在不同配比、不同电压形式（工频和负极性雷电冲击）作用下的击穿特性。试验结果表明，气压在0．25MPa以下时，适当增大SF6混合气体的压强可以使其达到纯SF6相同的绝缘强度，为新型C—G…
The Monte Carlo (MC) method is a class of computational algorithms that rely on repeated random sampling to simulate complex statistical behaviors and compute their results. In physics and material science, the MC method is especially useful for simulating systems with many coupled degrees of freedom. In this article,…
Poly (vinyl alcohol)(PVA)/poly(acrylonitrile)(PAN) blend film was prepared and the properties of the blend film were characterized to study the possibility of property improvement of PVA for reinforcing materials. From the patterns of wide-angle X-ray diffraction of the blend films, diffraction peaks from each polymer…

根据热力学平衡原理，绘得Cu（OH）2-CuSO4-H2O体系在298．15K条件下的平衡pc-pH图。pc．pH图描述了不同铜离子的平衡浓度与pH值关系：pH值在3．49～4．76时，CuSO4的溶解度最小；pH值在7．32～10．68时，Cu（OH）2的溶解度最小。同时查明了Cu（OH）2和CuSO4在水中共同存在时对溶解度相互影响的规律。研究结果可为含铜废液的处理及铜的回收利用提供理论依据。
The article considers a method to reconstitute contact conditions and mechanical characteristics of loading a compound pillar without regard to regularization. The stepwise approximation algorithm has been constructed, and it is shown in the article that the discrepancy of an approximate solution and an exact solution…
Thermo-electricity offers an elegant solution to the problem of heat-to-electricity conversion. As a completely solid-state heat engine, thermoelectric materials confer many advantages in electricity generation and heat pumping. However, the efficiency of thermoelectric material, represented by the figure of merit, Z,…
The deconstruction and upgrading of lignocellulosic biomass dissolved in ionic liquids was studied as a potential alternative route to products traditionally synthesized from petroleum. While domestic biomass is a cheaper, lower carbon emission, alternative feedstock to petroleum, its utilization requires the selectiv…
The subject of this thesis is the metallurgical stability of an alloy selected for use in a ceramic oxide fuel cell. Fuel cells are a new and developing power generation technology with numerous designs and materials being considered for the construction of fuel cells.
