Guiding of relativistic electron beams in dense matter by laser-driven magnetostatic fields

Nature Communications, 2018
Efficient energy transport by laser-driven relativistic electron beams is crucial in many applications including inertial confinement fusion, and particle acceleration.

Ekman-Inertial Instability

, 2020
We report on an instability, arising in sub-surface, laterally-sheared geostrophic flows. When the lateral shear of a horizontal flow in geostrophic balance is of opposite sign to the Coriolis parameter, and exceeds it in magnitude, embedded ...

Designing Vanadium‐Based Oxide Electrocatalysts for Water Splitting: Experimental and Mechanistic Insights with Machine Learning

Advanced Functional Materials, EarlyView.
This review establishes structure‐property‐mechanism relationships across six modification strategies for V‐based oxide water‐splitting electrocatalysts: lattice engineering, heteroatom doping, interface engineering, carbon‐based hybridization, morphology engineering, and surface reconstruction and pre‐catalyst design, where dissolution is reframed as ...

Dimensionality‐Driven Interfacial Electronic Coupling in Carbon‐Supported Gd‐CuO Catalysts for Selective CO2 Electroreduction to Ethylene

Advanced Functional Materials, EarlyView.
The 2D carbon‐supported Gd–CuO exhibits strong interfacial electronic coupling, abundant oxygen vacancies, and highly exposed active sites, enabling efficient CO enrichment and C─C coupling toward selective and durable CO2‐to‐C2H4 conversion. ABSTRACT Copper‐based catalysts are promising for electrochemical CO2 reduction toward value‐added chemicals ...

Rescattering of stimulated Raman side scattering in nonuniform plasmas

Matter and Radiation at Extremes
Rescattering of stimulated Raman side scattering (SRSS) is observed for the first time via two-dimensional (2D) particle-in-cell (PIC) simulations. We construct a theoretical model for the rescattering process, which can predict the region of occurrence ...

Monte Carlo-based simulation of x-ray phase-contrast imaging for diagnosing cold fuel layer in cryogenic implosions

AIP Advances, 2019
Diagnosing the layered cryogenic DT implosions with traditional absorption based x-ray backlight radiography in inertial confinement fusion is a challenge because of the low opacity of the cold fuel.

Fabrication of solid CH-CD multilayer microspheres for inertial confinement fusion

Matter and Radiation at Extremes, 2021
Deuterated polymer microspheres can be used as a neutron source in conjunction with lasers because thermonuclear fusion neutrons can be produced efficiently by collisions of the resulting energetic deuterium ions.

Reusability of functionality-based application confinement policy abstractions [PDF]

, 2008
Traditional access control models and mechanisms struggle to contain the threats posed by malware and software vulnerabilities as these cannot differentiate between processes acting on behalf of users and those posing threats to users’ security as every ...
