Aerosol and NO x emission factors and submicron particle number size distributions in two road tunnels with different traffic regimes
Measurements of aerosol particle number size distributions (18–700 nm), mass concentrations (PM2.5 and PM10) and NO x were performed in the Plabutsch tunnel, Austria, and in the Kingsway tunnel,Expand

Liquid nitrogen fueled, closed Brayton cycle cryogenic heat engine
Abstract The use of liquid nitrogen as a combustion free and non-polluting vehicle ‘fuel’ has recently been demonstrated with the CooLN2Car, a liquid nitrogen powered vehicle. The CooLN2Car’s primaryExpand

Charged particle reflection from an artificially structured boundary that produces a spatially periodic magnetostatic field
Charged particle reflection away from an artificially structured boundary is studied by computer simulation. The artificially structured boundary produces a spatially periodic static magnetic fieldExpand

Fully kinetic plasma‐sheath theory for a cold‐electron emitting surface
The fully kinetic, one‐dimensional, plasma‐sheath theory by Schwager and Birdsall [Phys. Fluids B 2, 1057 (1990)] is further developed. A cold‐electron emitting surface is included and aExpand

Cold Thermal Storage and Cryogenic Heat Engines for Energy Storage Applications
A theoretical analysis is presented of heat engines that use the atmosphere as a hot reservoir and a cryogenic medium as a cold reservoir. These “cryogenic” heat engines can be used as zero emissionExpand

Early spring near-surface ozone in Europe during the COVID-19 shutdown: Meteorological effects outweigh emission changes
Abstract This paper analyses the impact of the control measures during the COVID-19 lockdown in Europe (15 March–30 April 2020) on 1-h daily maximum nitrogen dioxide (NO2) and maximum daily 8-hExpand

Loss rate of an electrically trapped non-neutral plasma
A non-neutral plasma in a Malmberg–Penning trap can be allowed to escape confinement in a controllable way, because the depth of the applied electric potential well used to confine the plasma axiallyExpand

Space-charge-based electrostatic plasma confinement involving relaxed plasma species
A numerical study is reported on the equilibrium properties of a surface-emitted or edge-confined non-drifting plasma. A self-consistent finite-differences evaluation of the electrostatic potentialExpand

Two-species mixing in a nested Penning trap for antihydrogen trapping
There exists an international quest to trap neutral antimatter in the form of antihydrogen for scientific study. One method that is being developed for trapping antihydrogen employs a nested PenningExpand
