A Study of Rocket Exhaust Particles [PDF]

open access: yes, 1996
The exhaust -plumes generated by rocket motors are of significant military importance for missile detection, recognition and communication due to their electromagnetic emission and propagation properties. The plume is a high temperature, high velocity

Individual aerosol particles from biomass burning in southern Africa: 1. Compositions and size distributions of carbonaceous particles [PDF]

open access: yes, 2003
Individual aerosol particles in smoke plumes from biomass fires and in regional hazes in southern Africa were studied using analytical transmission electron microscopy ( TEM), which allowed detailed characterization of carbonaceous particle types in ...

Complexity for charged thermofield double states

open access: yesJournal of High Energy Physics, 2020
We study Nielsen’s circuit complexity for a charged thermofield double state (cTFD) of free complex scalar quantum field theory in the presence of background electric field.

Particles and fragments in unused disposable face masks: A microscopic analysis

open access: yesInternational Journal of Occupational Safety and Health, 2022
Introduction: In the context of the COVID-19 pandemic, many governments mandated the wearing of face masks by law. New research shows that these masks contain and release microplastics. Methods: In the present work, five samples of surgical masks were

Acoustophoretic trapping of particles by bubbles in microfluidics

open access: yesFrontiers in Physics, 2023
We present in this paper a simple method to produce strategic acoustic particle capture sites in microfluidic channels in a controlled way. Air bubbles are intermittently injected into a micro-capillary with rectangular cross section during a flow motion

How Classical Particles Emerge from the Quantum World. [PDF]

open access: yes, 2010
The symmetrization postulates of quantum mechanics (symmetry for bosons, antisymmetry for fermions) are usually taken to entail that quantum particles of the same kind (e.g., electrons) are all in exactly the same state and therefore indistinguishable in

Pinning down the gauge boson couplings in WWγ production using forward proton tagging

open access: yesJournal of High Energy Physics, 2020
In this paper, we explore the potential of the LHC to measure the rate of pp → p WWγ p process, also to probe the new effective couplings contributing to the WWγ and WWγγ vertices.
