Forces on Dust Grains Exposed to Anisotropic Interstellar Radiation Fields [PDF]
, 2000 Grains exposed to anisotropic radiation fields are subjected to forces due to the asymmetric photon-stimulated ejection of particles. These forces act in addition to the ``radiation pressure'' due to absorption and scattering.

Experimental H2O formation on carbonaceous dust grains at temperatures up to 85 K
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT Water represents the main component of the icy mantles on dust grains, it is of extreme importance for the formation of new species and it represents the main component for life. Water is observed both in the gas-phase and frozen in the interstellar medium (ISM), where the solid-phase formation route has been proven essential to

Seepage and Dynamic Characteristics of Carbonaceous Mudstone Coarse‐Grained Soil Embankment with Different Gradations [PDF]
Advances in Civil Engineering, 2021 This study investigates the seepage and deformation characteristics of carbonaceous mudstone coarse‐grained soil embankment with different gradations under the action of dynamic load and rainfall. An indoor geotechnical test is conducted, and the mechanical parameters of carbonaceous mudstone coarse‐grained soil with different gradations are analyzed ...

Reduction of Lead Oxide by Fine-Grained Carbonaceous Materials
Archives of Metallurgy and Materials, 2019 As part of the presented work, tests were carried out to check the possibility of replacing of conventional reducers used in the lead pyrometallurgical processes by cheaper, but equally effective substitutes. For research of lead oxide reduction, the following fine-grained carbonaceous materials were used, ie anthracite dust and coal flotation ...
