Theory of Fast Electron Transport for Fast Ignition

open access: yes, 2013
Fast Ignition Inertial Confinement Fusion is a variant of inertial fusion in which DT fuel is first compressed to high density and then ignited by a relativistic electron beam generated by a fast (< 20 ps) ultra-intense laser pulse, which is usually ...

Multifunctional Properties of Wintergreen (Gaultheria procumbens) Essential Oil: Antimicrobial, Antibiofilm, and Insecticidal Effects

open access: yesFlavour and Fragrance Journal, EarlyView.
Unveiling the potential of Wintergreen (Gaultheria procumbens) essential oil. ABSTRACT This study investigated the antimicrobial, antibiofilm, and insecticidal properties of wintergreen (Gaultheria procumbens L.) essential oil (GPEO). The EO was chemically characterized by GC–MS, confirming methyl salicylate as the predominant compound (99.3%).

Nonlocal effects on the shock-augmented ignition scheme of laser inertial fusion

open access: yesPhysical Review Research
Shock-augmented ignition (SAI) has recently been proposed as a viable approach to optimize the shock ignition scheme of laser fusion, which may substantially reduce laser power and intensity requirements and, as a result, greatly inhibit the growth of ...

Studying solid fuel ignition by CO2-laser

open access: yesMATEC Web of Conferences, 2017
The ignition data on Siberian bituminous coal and lignite by a continuous CO2-laser were presented in current work. Measurements were carried out at the heat flux density range of 90–150 W/cm2 in air.

Hydrodynamic Implosion Simulation Including Relativistic Effects on Petawatt-Class Pulse Heating

open access: yes, 2003
A spherically symmetric fluid code that includes the relativistic effects of hot electrons has been newly developed. In the present simulations, I attempt to implode a target shell of laser fusion using a nanosecond pulse; then, an additional heating ...

Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces

open access: yesInfoMat, EarlyView.
A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

A Shock‐Tube Study of the HCl + M →$\to $ H + Cl + M (M = Ar) Rate Constant Using HCl Laser Absorption Near 3.3 µm

open access: yesInternational Journal of Chemical Kinetics, EarlyView.
ABSTRACT Hydrogen chlorine (HCl) is an important combustion intermediate during plastic (municipal waste) and composite propellant (aerospace) combustion, but the understanding of its high‐temperature chemistry is still evolving. In this study, the pyrolysis of 0.5% HCl in Ar was investigated behind reflected shock waves in a shock tube at temperatures
