Oil-in-water nanoemulsion adhesive system: Preparation by ultrasonic homogenization and its application in 3D direct writing composite energetic materials

Journal of Materials Research and Technology
Stable and low-particle size nanoemulsions were prepared using ultrasound homogenization. The conditions for preparing low-viscosity nanoemulsions were optimized using Response Surface Methodology (RSM) experimental design.

Proton Acceleration in Low-β Magnetic Reconnection with Energetic Particle Feedback

The Astrophysical Journal
Magnetic reconnection regions in space and astrophysics are known as active particle acceleration sites. There is ample evidence showing that energetic particles can take a substantial amount of converted energy during magnetic reconnection.

Energetic particle-mediated interplanetary shocks observed by Solar Orbiter

Astronomy & Astrophysics
Context. In collisionless shocks, energetic particles can carry enough pressure to modify the upstream plasma and the shock structure itself. This represents a regime that is often invoked in theories of cosmic-ray acceleration, but rarely observed in ...

Energetic Particle Observations at Synchronous Orbit : Multiple-Satellite Study for Flux Variation by GOES-2, GOES-3 and GMS and Nightside Flux Depression for Continuous Geomagnetic Activity by GMS (a. Precipitating Particles and Auroras) (Proceedings of the Second Symposium on Coordinated Observations of the Ionosphere and Magnetosphere in the Polar Regions : Part I)

Antarctic Record, 1980
This article reports the results of studying the behavior of the energetic particle flux obtained at synchronous orbit during substorms. The multi-satellite study has clearly showed that the evening particle flux decrease contrasts with the behavior in ...

Numerical investigation of particle acceleration at interplanetary shocks: Diffusive and superdiffusive scenarios

Astronomy & Astrophysics
Context. Energetic particles are ubiquitous in space and astrophysical plasmas, and interplanetary shocks are widely regarded as one of the main particle accelerators in the heliosphere. Indeed, in situ measurements typically show that energetic particle
