Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

open access: yesAdvanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

On the relations between proton influx and D-region electron densities during the polar-cap absorption event of 28-29 October 2003 [PDF]

open access: yes, 2005
International audienceObservations by incoherent-scatter radar have been applied to explore relationships between the fluxes of incident protons and the resulting D-region electron densities during a polar-cap radio-absorption event.

High temporal resolution observations of auroral electron density using superthermal electron enhancement of Langmuir waves

open access: yesGeophysical Research Letters, 2016
We report high temporal resolution auroral electron precipitation observations using the Sondrestrom incoherent scatter radar. The observations make use of the superthermal electron enhancement of Langmuir waves, which is shown to give accurate ...

Multimodal Data‐Driven Microstructure Characterization

open access: yesAdvanced Engineering Materials, EarlyView.
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

The role of the tongue-of-ionization in the formation of the poleward wall of the main trough in the European post-midnight sector

open access: yes, 2008
A series of radio tomography reconstructions from the University of Wales Aberystwyth receiver chains in Scandinavia and the UK, imaging the midnight-dawn sector on 13 December 2001, reveal a persistent large-scale electron density enhancement, which ...

Precipitation-driven self-sintering for flexible electronics

open access: yesiScience
Flexible electronics (FE) require conductive materials that can be processed at low-temperature without compromising mechanical compliance. Here, we report a precipitation-driven self-sintering strategy that the highly conductive InGa3 film is formed on the flexible hydrogel under the ambient condition, and the solution-processable system is designed ...

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing

open access: yesAdvanced Engineering Materials, EarlyView.
The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...
