We report the nanoscale loading and confinement of aquated Gd3+n-ion clusters within ultra-short single-walled carbon nanotubes (US-tubes); these Gd3+n@US-tube species are linear superparamagnetic molecular magnets with Magnetic Resonance Imaging (MRI) efficacies 40 to 90 times larger than any Gd3+-based contrast agent (CA) in current clinical use.
The hysteretic and reversible polarity-dependent resistive switch driven by electric pulses is studied in both Ag/Pr0.7Ca0.3MnO3/YBa2Cu3O7 sandwiches single-layer Pr0.7Ca0.3MnO3 strips. data demonstrate that the takes place at Ag–Pr0.7Ca0.3MnO3 interface. A model, which describes well, proposed. We further suggest electrochemical migration cause for switch.
We investigate the polarity-dependent field-induced resistive switching phenomenon driven by electric pulses in perovskite oxides. Our data show that is a common occurrence restricted to an interfacial layer between deposited metal electrode and oxide. determine through impedance spectroscopy no thicker than 10 nm switch accompanied small capacitance increase associated with charge accumulation. Based on I-V characterization measurement of temperature dependence resistance, we propose...
Fusion for Energy (F4E), the European Domestic Agency International Thermonuclear Experimental Reactor (ITER) is responsible manufacturing, test and delivery of 5 out 6 Poloidal Field Coils ITER. F4E has currently delivered 4 coils: PF2, PF4, PF5 PF6, last two are installed in Tokamak pit temporary positions while PF2 PF4 stored awaiting torus completion. At PF coils manufacturing production site Cadarache, France, few meters away from ITER assembly building, finalizing testing largest coil:...
The superconducting coils of the ITER magnet system have hundreds electrical lap joints interconnecting cables. operate in a magnetic field up to 4 T, derivatives 0.5 T/s, and currents 70 kA. acceptance tests for toroidal (TF), poloidal (PF), correction coil (CC) will be performed at 77 K, before they are assembled pit. Hence there no possibility measure resistance state whole is enclosed Tokamak cryostat. In addition, reliable nondestructive method has been found spot with failure room...
The hole concentration (p)(delta), the transition temperature Tc, intragrain penetration depth lambda, and Meissner effect were measured for annealed RuSr2(Gd,Ce)2Cu2O10+delta samples. superconducting Tc} varied from 17 to 40 K while p changed by only 0.03 holes/CuO2. superfluid-density 1/lambda^2 diamagnetic drop of field-cooled magnetization across Tc (the effect), however, increased more than 10 times. All these findings are in disagreement with both vs. correlations proposed homogeneous...
A fabrication process of iron-clad MgB2 superconducting tapes was developed by using a nano-sized precursor and highly deformed iron sheath. Quenching experiments demonstrate that the fully reacts forms under high pressure 600?MPa provided Very good grain connections as well core density 2.55?g?cm?3 were therefore obtained. High 20?K Jc 3.1 ? 105, 1.6 105 4.9 104?A?cm?2 at self-field, 1 2?T, respectively, acquired. The results suggest approach to fabricate tape is very promising process.
In the ITER machine, two sets of three pre-compression rings will be installed at top and bottom 18 toroidal field coil structures. The tightly hold coils with a radial force 4,800 t per against operating forces. Four other serve as spares. Weighing 3.4 each, an inner diameter 5 m, made pultruded S-fiberglass composite are possibly largest most highly stressed structures to designed for cryogenic environment. All 10 have been delivered tested ring facility double nominal stress level. is...
Fusion for Energy (F4E), the European Domestic Agency International Thermonuclear Experimental Reactor (ITER), is responsible supply of 5 out 6 Poloidal Field (PF) Coils: PF2-PF6. One coil, PF1, being manufactured by Russian Federation (RFDA). While 10 m diameter PF6 was Institute Plasma Physics Chinese Academy Sciences (ASIPP) and tested in cold test facility at Cadarache under a collaboration agreement with F4E; coils PF2-PF5 are currently on site, close to Tokamak building, their size...
The ITER Correction Coils (CC) system consists of 3 sets 6 coils each: Bottom (BCC), Side (SCC) and Top (TCC) Coils. CC are supplied in-kind by the Chinese Domestic Agencies (CNDA) construction is carried out Academy Science Institute ASIPP. BCC TCC have been delivered to Organization. Whereas planar coils, SCC wound on a cylinder require completely different line manufacturing. at stages last manufacturing processes, between assembly terminal service box (TSB) Final Acceptance Tests (FAT)....
In the International Tokamak Experimental Reactor (ITER), six Poloidal Field (PF) ring coils are employed to initiate, stabilize, and shape plasma.

The influence of (Y/sub 0.8/Ca/sub 0.2/)Ba/sub 2/Cu/sub 3/O/sub y/ (YCBCO) over-layers on YBCO film properties has been studied multi-layer YBCO/YCBCO films. films were deposited [001] MgO single-crystal substrates by pulsed-laser deposition. results unambiguously demonstrate that a YCBCO over-layer can greatly improve the overall crystallinity and thus their J/sub c/. An optimal layer-number (n) (n layers)/YCBCO (n-1 layers) identified to produce maximum c/ enhancement. observations suggest...
