In this study, we report the effect of cooling from the peak temperature reached during partial melt processing on the critical current for a Bi2212/Ag wire. A single-stage cooling approach is compared to two-stage cooling. For two-stage cooling, the first stage cooling rate and the cooling rate transition temperature…
MOFs und MOPs: Die kooperative Anordnung von Indiumknoten mit vierfacher Konnektivität und zwei Liganden komplementärer Symmetrie ergibt Dreierring-basierte Metall-organische Zeolithgerüste vom NPO-Typ (NPO-Zeolith-MOFs) und Metall-organische Johnson-Polyeder (Johnson-MOPs; grau C, grün In, blau N, rot O). Die NPO-Zeo…
Abstract High temperature X‐ray diffraction (XRD) is used to characterize residual stress depth‐profiles and volume‐averaged residual stresses in blasted 9 µm thick TiN coatings on WC/Co substrates in the temperature range of 25–1100 °C using a dedicated high temperature attachment from Anton Paar GmbH. Room temperatu…
We have fabricated the TaN-[SiO2-LaAlO3]-HfON-[LaAlO3-SiO2]-Si charge-trapping Flash device. A large 6.4-V initial memory window, a 4.3-V 10-year extrapolated reten tion window at 125°C, and a 5.5-V endurance window at 106cycles were measured under very fast 100-μs and low ±16-V program/erase. These excellent results…
We have studied the thickness (t) dependence of the critical-current density (Jc) of epitaxial YBCO films grown by fluorine-free MOD to understand the origin of strong depletion ofJcby film thickening. We have grown more than thirty samples with t varied from 0.2 to 1.4 μm, and obtained a detailedJc-vs-t relation with…
An electrically waveform controllable optical chopper based on holographic polymer dispersed liquid crystal grating (H-PDLC) is presented in this paper. The theoretical analyses and experimental results show that the proposed optical chopper has following merits: (1) controllable waveform, (2) no mechanical motion ind…
In the superconducting applications, the wires are exposed to time-varying magnetic field when the current changes. This generates losses which can be minimized by reducing filament size, twisting the wire, and increasing the transverse resistivity. However, the high losses of magnesium diboride wires often arise from…
Mixtures of hard hyperspheres in odd-space dimensionalities are studied with an analytical approximation method. This technique is based on the so-called rational function approximation and provides a procedure for evaluating equations of state, structure factors, radial distribution functions, and direct correlation…
OBJECTIVE: The purpose of this article is to compare in vitro T1rho measurements in agarose phantoms and articular cartilage specimens using 2D multislice spiral and 3D magnetization prepared partitioned k-space spoiled gradient-echo snapshot MRI sequences. MATERIALS AND METHODS: Six phantoms (agarose concentration, 2…
Drinnen und draußen: Eine Herausforderung bei der Funktionalisierung von Nanopartikel-Oberflächen ist das Anbringen einer einzigen funktionellen Gruppe oder mehrerer spezifischer Moleküle in kontrollierter Orientierung und Entfernung voneinander. Nun gelang es, räumlich adressierbare selbstorganisierte DNA-Nanokäfige…
High frequency signal propagation in shielded power cable is important to many cable diagnostic techniques including time domain reflectometry, partial discharge location, etc. The signal propagation characteristics, including electromagnetic propagation velocity, cable characteristic impedance, and attenuation are we…
An integrated and compact model for probability of failure in carbon nanotube field-effect transistors (CNFETs) that includes 1) void CNFETs, 2) carbon nanotube (CNT) density variation, and 3) metallic CNTs is presented based on binomial probability distribution. Comparison with experimental data shows that the compac…
YtvA from Bacillus subtilis was found as the first prokaryotic phototropin-like blue-light-responsive photoreceptor. It is composed of two domains, the photoactive LOV (light, oxygen, voltage) domain, which binds a flavin mononucleotide (FMN) as a chromophore and a STAS (sulfate transporter/anti-sigma-factor antagonis…
The total solubility S T of (CH 2 ) 2 i −2 N i (CH 2 COOH) i +2 complexons ( i = 1, nitrilotriacetic acid (NTA); i = 3, diethylenetriaminepentaacetic acid (DTPA); i = 4, triethylene tetraaminehexaacetic acid (TTHA)) in aqueous NaCl solutions at different ionic strengths, (0 ≤ I ≤ 5) mol·L −1, and at 298.15 K are deter…
This study analyzes the loss peak frequency of an integrated ferromagnetic noise suppressor by evaluating the demagnetizing field. An integrated ferromagnetic noise suppressor is fabricated using a regular silicon process, and relation between the loss peak frequency and demagnetizing field is evaluated. The demagneti…
One of the prerequisites to the development of a simulated moving bed (SMB) or a temperature-gradient SMB process for separation of succinic acid and lactic acid is to obtain their adsorption equilibrium data on a properly selected adsorbent. It was first found that an Amberchrom CG300C resin could function well as a…
The integrity, chemical identity, packing density, and molecular orientation in SAMs formed by anthracene-substituted alkanethiols (Ant- n ) with a variable number of methylene groups ( n ) in the aliphatic linker on Au(111) and Ag(111) substrates were studied by a combination of several complementary experimental tec…
Abstract The alignment and the aggregation of particles in a viscoelastic fluid in simple shear flow are qualitatively analyzed using a two‐dimensional direct numerical simulation. Depending on the shear thinning, solvent viscosity, and Weissenburg number, a typical sequence in structural transitions from random parti…
In this study, four kinds of coupling agents (i.e., silane KH550, silane KH560, titanate NXT-102, titanate NXT-201), were used to modify the surfaces of aluminum (Al) particles. The effects of these coupling agents on the microstructures and dielectric properties of the Al/epoxy composites were investigated by the sca…
The decomposition of PET during thermal treatment of municipal waste results in the formation of sublimating substances such as terephthalic acid (TPA) and benzoic acid, causing blockage and corrosion of pipes in the treatment facilities. To prevent these effects, TPA can be decarboxylated in the presence of calcium o…
