A general boundary mapping method is proposed to enable the designing of various transformation devices with arbitrary shapes by reducing the traditional space-to-space mapping to boundary-to-boundary mapping. The method also makes the designing of complex-shaped transformation devices more feasible and flexible. Usin…
Anti-dermatophytic activity of foliar extract of Calotropis procera in different solvents (petroleum ether, chloroform, ethyl acetate and ethyl alcohol) was determined using paper disc diffusion method against three target fungi Microsporum canis (MTCC 3270),Microsporum fulvum (MTCC 7675) and Trichophyton mentagrophyt…
Aging-induced domain memory in acceptor-doped perovskite ferroelectrics associated with ferroelectric-ferroelectric transition cycle, Gao, Jing-Hui, Xue, Dezhen, Zhang, Lixue, Wang, Yu, Bao, Huixin, Zhou, Chao, Liu, Wenfeng, Chen, Wei, Ren, Xiaobing
Abstract A thermoplastic vulcanizate (TPV) substrate was coated with a thin conductive film of titanium nitride (TiN), by dc reactive sputtering, aiming to develop polymer‐based electrodes for bio‐signal acquisition, namely for electroencephalographic (EEG) and electrocardiographic (ECG) applications. After the prepar…
ABSTRACT Derivation of optimal operating policies and runaway boundaries for a semibatch reactor (SBR), when highly exothermic reactions are conducted and hazardous side reactions may occur, is a difficult task because of multiple sources of process uncertainty to be considered (variability in raw materials, catalyst,…
Fiber reinforced polymers (FRP) are increasingly used for repairing corrosion-damaged concrete structures. The performance of the repairs is critically dependent on the oxygen permeability of the FRP-concrete system. This paper presents the results of an experimental study in which the oxygen permeation of concrete an…
Phase-shifting effect of EUV masks with various absorber thicknesses has been studied both by simulations and experiments. In EUV lithography, masks with 180 phase shifting absorber work like embedded attenuated phase-shifting masks. At 66nm thickness of TaN/TaON absorber, 180 degree phase shifting can be achieved in…
The interaction of parallel conducting perylene and insulating spin-1/2 $[\text{Pt}{(mnt)}_{2}]$ molecular chains in ${(Per)}_{2}{[\text{Pt}(mnt)}_{2}$] is investigated through the magnetic field dependence of their coupled Peierls (charge density wave - CDW) and spin-Peierls (SP) ground states. Proton NMR is used to…
This study was performed to determine the effects of thermal aging on the film hardness of some wood varnishes. For this purpose, Scots pine (Pinus sylvestris L.), Eastern beech (Fagus orientalis L.), and oak (Quercus petraea L.) samples coated with synthetic (alkyd), two-part polyurethane (urethane-alkyd), and waterb…
Abstract Chemoselective polycondensation of 2-amino-4,6-dichloro-1,3,5-triazine (ADCT) was investigated with various aromatic diamines such as 4,4′-oxydianiline (ODA), 9,9-bis(4-aminophenyl)fluorene (BAFL), 4,4′-(hexafluoropropane-2,2-diyl)dianiline (BisAF), and bis(4-aminophenyl)sulfone (SODA) in the presence of pota…
We studied experimentally the effect of a stripelike domain structure in a ferromagnetic BaFe${}_{12}$O${}_{19}$ substrate on the magnetoresistance of a superconducting Pb microbridge. The system was designed in such a way that the bridge is oriented perpendicular to the domain walls. It is demonstrated that depending…
Abstract A series of anthracene derivatives, 9,10-bis(bipyridyl, pyridylphenyl, phenylpyridyl, and biphenyl)anthracenes, were synthesized. They exhibited properties of small electron injection barrier from cathode in electron-only devices, high electron mobility from time-of-flight measurement, and high efficiency and…
Abstract Cyclo(l-aspartyl-l-phenylalanyl)-containing poly(dimethylsiloxane) was synthesized through a simple procedure. This compound had a good organogelation or thickener ability in many organic solvents. X-ray diffraction showed that the gelator forms amorphous structure due to the presence of poly(dimethylsiloxane…
Amorphous chalcogenide semiconductors have commercial value and have many uses such as image formation, including x-rays, and high-definition TV pick up tubes. They have widespread application in the microelectronics industry and amorphous metallic alloys also have useful magnetic properties. This book focuses on thei…
In a biorefinery context it is an advantage to fractionate and extract different wood components in a relatively pure form. However, one major obstacle for efficient extraction of wood polymers (lignin, polysaccharides etc.) is the covalent lignin-polysaccharide networks present in lignified cell walls. Enzymatic cata…
Nanoscale potassium niobate (KNbO3) powders of orthorhombic structure were synthesized using the sol-gel method. The heat-treatment temperature of the gels had a pronounced effect on KNbO3 particle size and morphology. Field emission scanning electron microscopy and transmission electron microscopy were used to determ…
In this paper, a fast convolution method using scattering parameters is presented for the macromodeling of blackbox multiport networks. The method is compared to model-order reduction passive macromodeling techniques in terms of robustness and computational efficiency. When scattering parameters are used as the transf…
α-Actinins form antiparallel homodimers that are able to cross-link actin filaments. The protein contains three domains: an N-terminal actin-binding domain followed by a central rod domain and a calmodulin-like EF-hand domain at the C-terminus. Here, crystallization of the rod domain of Entamoeba histolytica α-actinin…
The purpose of this study was to evaluate the effective dose to family members of thyroid cancer and hyperthyroid patients treated with radioiodine-131, and also to compare the results with dose constraints proposed by the International Commission of Radiological Protection (ICRP) and the Basic Safety Standards (BSS)…
Influence of local loads on the stress state of the shell appears as the consequence of pressure, external forces, and moment influence. Loads which act directly upon the shell surface or the parts (nozzles) connected to the shell appear in their proximity, especially in the welded joint influence zones. The influence…
