Quasi-linear transport analysis of impurity mode in tokamak plasmas

Nuclear Fusion
The quasilinear turbulent particle and heat transports induced by the impurity mode (IM), driven by the opposite gradients of the core hydrogen and outer $\mathrm{C}^{6+}$ , $\mathrm{O}^{6+}$ , $\mathrm{O}^{8+}$ and $\mathrm{Ne}^{8+}$ ions, are shown to ...

Global effects on neoclassical transport in the pedestal with impurities

, 2016
We present a numerical study of collisional transport in a tokamak pedestal in the presence of non-trace impurities, using the radially global $\delta f$ neoclassical solver PERFECT [M. Landreman et al. 2014 Plasma Phys. Control. Fusion 56 045005]. It is

Copper Nanocrystallization in Anodic Oxide Films of Ti–Cu‐Based Bulk Metallic Glass and Its Effect on the Corrosion Resistance and Cytocompatibility

Advanced Engineering Materials, EarlyView.
Viktoriia Shtefan, Thorgund Nemec, Ute Hempel, Annett Gebert and coworkers demonstrate that anodic treatment of Ti–Cu‐based metallic glass in a nontoxic pyrophosphate electrolyte forms a protective bilayered Ti/Zr‐oxide film enriched with Cu nanocrystals.

Dispersion considerations affecting phonon-mass impurity scattering rates

AIP Advances, 2011
This work presents a derivation of phonon-mass impurity scattering rates applicable to dispersive phonon systems. This form of mass impurity scattering is compared with the previously accepted form assuming a nondispersive crystal by calculating the ...

Evaluation of Plasticity and Creep Parameters From Tensile Stress–Strain Data for a Range of Strain Rates

Advanced Engineering Materials, EarlyView.
This plot compares experimental tensile stress–strain curves (with 4 different strain rates) and corresponding modelled curves (obtained using the optimised sets of Voce and Miller–Norton parameter values shown). The inferred M‐N values, characterizing the creep, are very similar to those obtained via conventional creep testing.

Computer simulations of an impurity in a granular gas under planar Couette flow

, 2011
We present in this work results from numerical solutions, obtained by means of the direct simulation Monte Carlo (DSMC) method, of the Boltzmann and Boltzmann--Lorentz equations for an impurity immersed in a granular gas under planar Couette flow.

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

Advanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Simulation study on global migration of locally generated impurity in JT-60U

Nuclear Materials and Energy
The transport of carbon and neon particles locally emitted from plasma facing components under the JT-60U L-mode plasma condition is investigated by the integrated divertor code SONIC. In this analysis, an impurity point source emitting a small amount of
