Transport of short-lived halocarbons to the stratosphere over the Pacific Ocean [PDF]

Atmospheric Chemistry and Physics, 2020
The effectiveness of transport of short-lived halocarbons to the upper troposphere and lower stratosphere remains an important uncertainty in quantifying the supply of ozone-depleting substances to the stratosphere.

Effects of matrix viscosity on morphological and rheological properties and the electrical percolation threshold in graphene/epoxy nanocomposites

eXPRESS Polymer Letters, 2021
Graphene nano-platelets (GNPs) can substantially improve the performance of epoxy resin, but improving effects are highly dependent on GNP dispersion uniformity in the matrix.

The Slope of the Black Hole Mass versus Velocity Dispersion Correlation [PDF]

, 2002
Observations of nearby galaxies reveal a strong correlation between the mass of the central dark object MBH and the velocity dispersion σ of the host galaxy, of the form log(MBH/M☉) = α + β log(σ/σ0); however, published estimates of the slope β span a ...
