Deuterium retention in tungsten and tungsten alloys exposed to pure and impurities seeding deuterium plasma

Nuclear Materials and Energy, 2020
Polycrystalline tungsten (W) and four kinds of tungsten alloys were exposed to pure and impurities seeding deuterium (D) plasma to investigate the deuterium retention behaviour. The results show that D retention in W increases with the increasing fluence

Graphene Layers as Functional Biomaterials. From Fabrication and Characterization to Biological Applications

Advanced Materials Interfaces, EarlyView.
Graphene layers are fabricated on Cu foil and transferred onto glass substrates to form double‐ and multi‐layer G‐glass. Raman spectroscopy confirms structural integrity, while SEM and fluorescence microscopy reveal favorable adhesion and spreading of L‐929 fibroblast cells.

Impurity-free seeded crystallization of amorphous silicon by nanoindentation

Journal of Applied Physics, 2011
We demonstrate that nanoindents formed in amorphous Si films, with dimensions as small as ∼20 nm, provide a means to seed solid phase crystallization. During post-indentation annealing at ∼600 °C, solid phase crystallization initiates from the indented sites, effectively removing the incubation time for random nucleation in the absence of seeds.

Nanoporous Silica Embedded in Nanoporous Platinum: A Versatile Composite Coating for Implant‐Associated Drug Delivery From Neuronal Electrodes

Advanced Materials Technologies, EarlyView.
Nanoporous silica nanoparticles incorporated in nanoporous platinum offer the possibility for implant‐associated drug delivery from neuronal electrodes. ABSTRACT Sensorineural hearing loss, resulting from damage to the hair cells of the inner ear, profoundly impairs quality of life.

Simulation study of mixed-impurity seeding with extension of integrated divertor code SONIC

, 2020
Aimed at obtaining key physics that determine the controllability of impurity transport in the scrape-off layer (SOL)/ divertor regions, the integrated divertor code SONIC has been further extended to handle three or more impurity species kinetically ...
