The transient charging/discharging of electrons in Ge-nanocrystal (NC) memories are measured by a pump-and-probe method that allows keeping track of the number of electrons per NC. The experiments are simulated with a quantum kinetic mechanical model based on the density-functional theory, which can describe the NCs'…
We review recent work in which a methodology has been developed for solving the Landau-Lifshitz equation in its most general form, along with Maxwell's equations. The method has been applied to the solution of problems of giant magnetoimpedance and ferromagnetic resonance. Conditions for chaotic behavior have been exp…
SUMMARY The Tokyo Electric Power Company, Inc (TEPCO) plans 1100 kV power network system in Japan in order to meet the steady increasing demand for electricity. Four‐hundred kilometer 1100‐kV‐designed double‐circuit transmission lines have already been constructed and are now operated at 550 kV. 1100‐kV substation equ…
Polyelectrolyte multilayer (PEM) transfer printing has been previously achieved by stamping under dry conditions. Here, we show for the first time, that PEM can be transferred from a stamp to the base substrate under aqueous conditions whereby the two surfaces are in a non-contact mode. Degradable multilayers of (PAA/…
Abstract The paper reviews the developments made for designing and fabricating a piezoelectric driven actuator and its integration into coplanar wave guide (CPW) microwave structures. In the first part of this work the electromechanical properties of different lead–zirconate–titanate (PZT) thin films are investigated.…
A novel transparent Al-doped ZnO (AZO)-gated Al0.2Ga0.8As/In0.2Ga0.8As pseudomorphic high-electron mobility transistor (pHEMT) has been comprehensively investigated. The proposed AZO-gated pHEMT has demonstrated superior temperature-dependent performance, including two-terminal gate-drain breakdown/turn-on voltages of…
In this paper, we assessed the characteristics of the rotational energy loss by drag force according to a size change of the new amorphous stator core used on PMSM/G. The accurate method for measuring rotational energy was presented through the spin down test using superconductor flywheel energy storage system (SFES).…
Two-Photon luminescence (TPL) from gold nanorods shows considerable potential in biological imaging for high resolution, low photo-damage, tunable near infra-red (NIR) longitudinal band, polarization dependence, ability to conjugate to bio-molecules and low toxicity. Here we demonstrate the application of gold nanorod…
In this study, we investigated the in vivo application of an integrated small-animal magnetic resonance (MR) and gamma-ray imaging system that consists of a semiconductor-based radiation detector, a parallel-hole collimator, and a specialized radiofrequency coil. Gadodiamide and (99m)Tc sestimibi agents were injected…
The quaternary hydride CeZnSnH 1.5 was synthesized from a CeZnSn precursor upon hydrogenation at 553 K and 4 MPa H 2 pressure. Single-crystal X-ray diffraction data reveal that the metal atoms adopt an YPtAs-type structure: P 6 3 / mmc, a = 449.34(9) and c = 1731.3(4) pm, w R 2 = 0.0493, 218 F 2 values, and 12 variabl…
Abstract A series of polythiophene derivatives bearing 3,4‐diaryl substituents were synthesized starting from commercially available 3,4‐dibromothiophene. The effects of two different aryl substituents, either a 5‐octyl‐2‐thienyl or a 4‐octylphenyl, were investigated in this study. To minimize steric effects on polyme…
This letter reports on a study of the emission properties of organic light-emitting diodes (OLEDs) controlled by an organic photo sensor (OPS) based on poly-3-hexylthiophene (P3HT) and [6, 6]-phenyl-C61butyric acid methyl ester for emotional lighting applications. The emission characteristics exhibit the changes in th…
We present results of a series of experiments performed on LiBr, 6H(2)0 from room temperature down to 172 K ≈ 1.2T(g). These ultrasound, Brillouin and depolarized light scattering, and transient grating experiments show that, above 215 K, this solution behaves like supercooled water: its zero frequency sound velocity…
Controlled release is a chemical activation method, which is provided to specific plant species at preset rates and times. Different polymers are largely used to control the delivery rates, mobilities, and the chemicals period of effectiveness. The main benefit of the controlled release method is that if fewer chemica…
Phylogenetic reconstructions using parsimony, maximum likelihood (ML), and Bayesian relaxed molecular clock analyses of ∼2850 nucleotides of nuclear-encoded small and large subunit ribosomal DNAs (SSU and LSU rDNAs) from 14 long-looped (terebratelloid) ingroup and four short-looped (terebratulidine) outgroup brachiopo…
The surface diffusion of In atoms from an In droplet and their subsequent reaction with As 4 molecules lead to the formation of InAs quantum dots elliptically distributed around the initially formed droplet. The size of this elliptic dot cluster depends sensitively on the growth conditions. For instance, as the substr…
Haloalkane dehalogenases make up an important class of hydrolytic enzymes which catalyse the cleavage of carbon-halogen bonds in halogenated aliphatic compounds. There is growing interest in these enzymes owing to their potential use in environmental and industrial applications. The haloalkane dehalogenase DhaA from R…
The encapsulation method is used in the textile detergents and softeners industry to provide a long-lasting fragrance. Capsules currently employed show low encapsulation capacity and stability. However, polysulfone (PSf) microcapsules were proposed, as they show promising results. To characterize PSf capsule morpholog…
Moisture content affects most of the important properties of wood, therefore it is important to control during drying and in use. The purpose of this study was to investigate moisture content changes in Taiwan red cypress during drying. Two types of nondestructive testing were used, ultrasonic and tap-tone. The result…
Buried pipelines can be subject to transitional environments due to changes in soil type or moisture content. Changes in the height of the water table, for example, will affect not only the availability of water but also the access of oxygen to the pipe surface. Transitions between different soil types will also resul…
