Dust emission in powder handling: Free falling particle plume characterisation [PDF]

, 2009
Dust generation during solids handling, principally from the free falling of bulk materials and their impact on stockpiles, can be a health threat for operators and a cause of dust explosions.

Modelling soil dust aerosol in the Bodélé depression during the BoDEx campaign [PDF]

, 2006
We present regional model simulations of the dust emission events during the Bodélé Dust Experiment (BoDEx) that was carried out in February and March 2005 in Chad. A box model version of the dust emission model is used to test different input parameters

Dust emission by powder handling: Influence of the hopper outlet on the dust plume [PDF]

, 2011
Dust generation in solids handling involving free fall of bulk materials and impacts on a stockpile can cause many problems in industry and be a great danger for operators health. This paper describes an experimental set up to characterize the dust plume

The dynamism of salt crust patterns on playas [PDF]

, 2014
Playas are common in arid environments and can be major sources of mineral dust that can influence global climate. These landforms typically form crusts that limit evaporation and dust emission, modify surface erosivity and erodibility, and can lead to ...

Dust formation and evolution in the ejecta of core-collapse supernovae [PDF]

, 2015
Observations of local supernovae over the past couple of decades have reported the presence of dust in the ejecta. The dust masses inferred from observations in mid-infrared and submillimeter wavelengths differ by a factor of 10^2 to 10^4 The composition

Comparing Molecular Gas Tracers at z~2: Do CO and dust continuum emission trace the same regions of the ISM?

, 2020
We have compared resolved and unresolved observations of the CO and dust continuum emission from star-forming galaxies at z~2 (taken with ALMA). The molecular gas phase of the interstellar medium is a crucial component of star-forming galaxies, hosting ...

Millimeter dust continuum emission revealing the true mass of giant molecular clouds in the Small Magellanic Cloud [PDF]

Astronomy & Astrophysics, 2007
CO observations have been so far the best way to trace molecular gas in external galaxies, but at low metallicity the gas mass deduced could be largely underestimated. At present, the kinematic information of CO data cubes are used to estimate virial masses and trace the total mass of the molecular clouds. Millimeter dust emission can also be used as a

Spatially resolved thermal dust emission in the L1157 outflow reveals grain-driven molecular enrichment

Astronomy & Astrophysics
Context. Protostellar outflow shocks reshape local dust properties and molecular chemistry. The L1157 outflow is an archetypal chemically rich shocked region, but the thermal dust associated with its successive shocks has remained unresolved because ...
