We present the influence high heat treatment temperature of a nitrogen austenitic stainless steel, deform by cold compression, in 10 different percentages. The steel contains high chromium (19.25 %), nickel (1.5 %) and nitrogen (0.2 %). The typical applications for this alloy are automobile parts and special valves fo…
Our objective is to establish models which allow one to predict the hygro-mechanical properties of paper sheets based on the properties of the underlying fibrous network. Asymptotic homogenisation is used to determine rigorous effective properties of random networks numerically. The trend predicted by these random net…
Для анизотропного монокристалла PbSb2Te4 исследовано влияние температуры и легирования медью на его спектр отражения R(nu) от плоскости скола, перпендикулярной тригональной оси C3. Установлено, что спектр имеет сложную структуру, характеризующуюся резким подъемом отражения в дальней инфракрасной (ИК) области и двумя м…
High-intensity focused ultrasound (HIFU) is effective in both thermal ablations and soft-tissue fragmentation. Mechanical and thermal effects depend on the operating parameters and vary with the progress of therapy. Different types of lesions could be produced with the pulse duration of 5-30 ms, much longer than histo…
This thesis examines the redox and acid-base chemistry of TCNQF and TCNQF² in acetonitrile in comparision with those of TCNQ and TCNQF₄. The results describe a linear relationship between the number of fluoro substituents and the redox potential as well as the stability of TCNQFn and their anions. The disproportionati…
Carbon nanostructures are a very promising option as new materials in field emission (FE) devices. In this thesis, a number of current challenges in the application of such materials in FE devices are addressed. A new microwave-based method was developed to improve the FE properties of commercial carbon nanotubes (CNT…
This work presents results from three different topics that stand independent from each other. If one wants to find a common denominator connecting all these topics it might be porosity. Whereas the work described in the first chapter aimed at devising new methodologies to allow nominally unprocessable polymers assume…
In an attempt to take advantage of industrial wastes, Iron slag was used to prepare some of glass samples in an attempt to re-use. The following chemical formula has considered in the preparation process. (25 + x) % slag + (75 - x) % (Na2B4O7.10H2O), where x has varied among different values. The rapid quenching metho…
La-doped MnO 2 nanoparticles were synthesized by a facile sol-gel method.
The periodontal ligament (PDL) connects the tooth to the alveolar bone. It functions as a shock absorber, forms a barrier against pathogens, and provides sensory information. These capacities are lost when the PDL is damaged, or when teeth are lost. Replacing missing teeth with dental implants is increasingly popular.…
Изучен вопрос эффективности контролируемого формирования массивов кремниевых наночастиц на основе детальных исследований электронного строения многослойных нанопериодических структур a-SiOx/SiO2, a-SiOx/Al2O3 и a-SiOx/ZrO2. С применением синхротронного метода спектроскопии ближней тонкой структуры края рентгеновского…
We present a new approach for real-time, specific and sensitive detection of insulin using a graphene aptameric nanosensor. The nanosensor is configured as a graphene field effect transistor, where the graphene conducting channel was functionalized with a guanine-rich aptamer IGA3 that would form an anti-parallel G-qu…
Asian Journal of Chemistry, a Multidisciplinary Chemistry Journal is an Peer Reviewed International Journal and publishes from India. The journal has been established since January 1989 on a firm foundation of International Quality Research. This Journal encompasses all branches of chemistry and its sub – disciplines…
El cancer es una de las principales causas de mortalidad en todo el mundo, lo que pone de manifiesto que las terapias disponibles hoy en dia, no son optimas, siendo en muchos casos los efectos secundarios el gran problema. La nanotecnologia esta adquiriendo gran interes en este campo, en concreto, la aplicacion de nan…
In order to accurately represent a rotational hysteresis loss of magnetic materials, this paper proposes a novel identification method for an isotropic vector play model. The slope of shape functions for an isotropic vector play model is assumed to be an exponential function. Numerical results of alternating and rotat…
This paper introduces a fast time-periodic eddy current analysis using model order reduction (MOR) and time-periodic explicit error correction (TP-EEC) method. In this method, the size of the original system is reduced by MOR and simultaneously, the convergence to steady states is accelerated by TP-EEC. It is shown th…
The paper reports the improvement of tensile strength of single-crystal silicon (SCS) microstructures fully coated with sub-micrometer thick diamond like carbon (DLC) film using plasma enhanced chemical vapor deposition (PECVD). To minimize the deformations or damages caused by non-uniform coating of DLC, which has hi…
Reactor physics and fuel burnup are discussed in order to obtain a simple global view of the effects of nuclear reactor characteristics to fuel cycle system performance. It may provide some idea of free thinking and overall vision, though it is still a small part of nuclear energy system. At the beginning of this lect…
The use of high quality non-oriented electrical steel and of an innovative design for the magnetic cores of the electrical machines are very important, in order to minimize the value of the total energy losses. The energy losses are strongly influenced by the cutting technologies, and the producers of the electrical m…
Nanostructured alumina supported copper oxide granular sorbents were prepared by the sol-gel method. The properties of the sol-gel derived sorbents were compared with a similar commercial sorbent which has been used in the pilot scale moving-bed copper oxide process for flue gas treatment. The crushing strength of the…
