. By comparing the two-state and a three-state unfolding processes of proteins, the order of the unfolding free energy was always inconsistent with the order of stability observed. This raises the question about the accuracy of the evaluated unfolding free energy values of three-state models. In this chapter, the line…
A noncontact transfer device using a combination of ultrasonic levitation with flexure traveling wave has some advantage in clean environment and simple device configuration. This paper deals with the concept of a two-dimensional transfer device using ultrasonic levitation, and fundamental experiments. A prototype of…
The process of mullitization of kyanite concentrate was studied at different conditions of heat treatment (1400 - 1600 °C and 0.5 - 3.5 hours) and particle size of raw materials (38-300 ?m). Kyanite concentrate was obtained from ore-dressing of kyanite deposits of Mishidowan-Bafgh region at 100 km northeastern part of…
Will-be-set-by-IN-TECH discovered materials, and yet very little is known on few-layer graphene
Abstract The single‐electron transfer living radical polymerization (SET‐LRP) method in the presence of chain transfer agent was used to synthesize poly( N ‐isopropylacrylamide) [poly(NIPAM)] with a low molecular weight and a low polydispersity index. This was achieved using Cu(I)/2,2′‐bipyridine as the catalyst, 2‐br…
The molecular mobility of cooperative segmental (α-process) and local (β-process) motions in semicrystalline fluorinated parylene (PA-F) films has been studied using broadband dielectric spectroscopy in a wide temperature range. Particularly, the α-relaxation is, for the first time in a semicrystalline polymer, probed…
Abstract Two epoxy‐amine networks were toughened by using a nanophase separating antiplasticizer at various contents ranging from 0 to 20 mol % with respect to the epoxide. These model networks were chosen to differ markedly by their glass transition temperature in the absence of additive, namely 180°C and 114°C. Net…
BaTiO3 nanowires were grown in an amorphous aluminum oxide membrane from a sol-gel via electrophoresis. These had a ferroelectric coercive field of 5 kV/mm after undergoing a thermal treatment. This value is 12–16 times larger than the bulk value. Such enhancements are in agreement with local PFM measurements by other…
Irradiating with pulsed laser light induces high-speed optical switching of surface magnetization-induced second harmonic generation (MSHG) in Fe0.52Rh0.48 thin films at room temperature. The second harmonic rotation angle (θSH) of 25.0° was recorded in the irradiated film at 2000 Oe. This θSH value is as much as 740…
Chemical mechanical planarization (CMP) has become the process of choice for surface global planarization for materials surfaces in the fabrication of advanced multilevel integrated circuits (ICs) in microelectronic industry. The surface planarization in the CMP is mainly realized by the tribology behavior of nanopart…
In this paper, a new methodology is proposed to mitigate unbalanced voltage sag with phase jumps by Unified Power Quality Conditioner (UPQC) with minimum real power injection. Particle Swarm Optimization (PSO) has been used to find the solution of the objective function derived for minimizing real power injection of U…
Flux Reversal Machines can be easy to manufacture, are reliable and well suited for direct-drive applications. They also have the advantage that they can be controlled as standard synchronous PM machines. As for most of doubly salient machines, the machine design is relatively complicated due to the highly non-linear…
We report the first low voltage organic P3HT transistor over glass substrates and titanium oxynitride (TiOxNy) deposited by reactive r.f. magnetron sputtering. The transistor operating voltage was -3V with a maximum current of 1.11 μA. Charger carrier mobility (μ) was 0.01 cm2/Vs, threshold voltage (Vt) -0.5 V, on-off…
Abstract Mittels der Isotopenaustauschmethode SSITKA (steady‐state isotopic‐transient kinetic analysis) ergaben sich Rückschlüsse zum Mechanismus der Partialoxidation von Acrolein zu Acrylsäure an Mo/V/W‐Mischoxidkatalysatoren. Der Isotopenaustausch erfolgte mit den beiden Sauerstoffisotopen 16O2 und 18O2. Dabei finde…
The combined study of electron-density features in three substituted hydropyrimidines of the Biginelli compound family has been fulfilled. Results of the low-temperature X-ray diffraction measurements and density functional theory (DFT) B3LYP/6-311++G** calculations of these compounds are described. The experimentally…
In the present study, the impacts of G198N and W128F mutations on the recognition between Aurora A and targeting protein of Xenopus kinesin-like protein 2 (TPX2) were investigated using molecular dynamics (MD) simulations, free energy calculations, and free energy decomposition analysis. The predicted binding free ene…
In this work, a phenomenological approach is proposed to analyze the electrical transport through an insulating barrier in insulating/metallic bilayer systems using conductive atomic force microscopy. The influence of the substrate in the electrical properties of ferroelectric/ferromagnetic bilayers was studied in the…
Eddy current losses generated in the rotor of permanent magnet machines may lead to an excessive magnet heating. This can cause the magnets to get fully demagnetized so it is very important to analyze the losses on them. In high power application usually it is necessary to design solutions to reduce eddy current losse…
Graphene which is single or few atomic layer carbon atoms in a hexagonal network is emerging as a leader among the 2D nanoscale materials [1]. Structurally, graphene is free of defects, with all the carbon atoms linked together by strong and flexible bonds. This has made graphene to have unusual electronic, optical, m…
Axial magnetostriction in giant magnetostrictive materials with specific crystal orientation is highly anisotropic when changing magnetization direction. Based on a single-{111}-twin crystal growth model, this paper presents a domain rotation simulation of anisotropic magnetostrictions in 〈110〉 oriented crystals Tb0.3…
