Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

Advanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

Analysis of dynamic levitation process of the particle chain in a nonlinear standing wave field

Scientific Reports
This research delves into the dynamic behavior of acoustic levitation of the particle chain in a nonlinear standing wave field. Experimental acoustic levitation control tests reveal bifurcation and jump phenomena during dynamic adjustments to resonant ...

Drift-compression waves propagating in the direction of energetic electron drift in the magnetosphere

Solar-Terrestrial Physics, 2017
As shown within the gyrokinetic framework, drift-compressional waves can propagate in the magnetosphere in the direction of energetic electron drift. The plasma is assumed to be composed of cold particles with an admixture of hot protons with a Maxwell ...

Nonlinear wave-particle interaction upstream from the Earth's bow shock [PDF]

Nonlinear Processes in Geophysics, 2000
Well-defined ring-like backstreaming ion distributions have been recently reported from observations made by the 3DP/PESA-High analyzer onboard the WIND spacecraft in the Earth's foreshock at large distances from the bow shock, which suggests a local ...

Uniform Amorphization of Crystalline Silicon Surfaces Enabled by Deep Ultraviolet Femtosecond Laser Pulses

Advanced Engineering Materials, EarlyView.
Deep‐UV (258 nm) femtosecond pulses enable uniform amorphous silicon writing on Si(100)/(111) with a six‐fold larger fluence amorphization window than NIR methods. Optimized fluence and overlap yield 20–45 nm uniform and continuous amorphous layers. Microscopy shows sharp interfaces, and real‐time reflectivity reveals nanosecond melt–resolidification ...

Nonlinear dynamic evolution of energetic particle mode due to nonadiabatic wave-particle interaction

Nuclear Fusion
Adopting dedicated phase-space diagnostics, we analyze the nonlinear dynamic evolution of an energetic particle mode (EPM) due to nonlinear wave–particle interactions, including nonlinear frequency chirping and secular particle motion due to trapping and

Planning for Observations of the Plasma Waves by Sounding Rockets in Antarctica

Antarctic Record, 1975
The plasma wave observations in the polar ionosphere consist of two categories; the first is for the emission due to the particle precipitation and the second is for the emissions that are thought to be generated in the magnetosphere as a result of the ...
