The physics of wind-blown sand and dust [PDF]

open access: yesReports on Progress in Physics, 2012
The transport of sand and dust by wind is a potent erosional force, creates sand dunes and ripples, and loads the atmosphere with suspended dust aerosols. This article presents an extensive review of the physics of wind-blown sand and dust on Earth and Mars. Specifically, we review the physics of aeolian saltation, the formation and development of sand

The Physics of Dust Coagulation and the Structure of Dust Aggregates in Space [PDF]

open access: yesAstrophysical Journal, 1997
Even though dust coagulation is a very important dust-processing mechanism in interstellar space and protoplanetary disks, there are still important parts of the physics involved that are poorly understood. This imposes a serious problem for model calculations of any kind.

A physics-guided machine learning framework for enhancing dust storm visibility prediction in arid and semi-arid regions [PDF]

open access: yesScientific Reports
Dust sharply degrades visibility in arid and semi-arid regions, yet operational forecasting remains challenged by near-surface process errors in numerical weather prediction (NWP) and the poor generalization of purely data-driven models.

The new physics of dust in plasmas

open access: yesJournal of Physics: Conference Series, 2021
Abstract The new physics of dust, which arises due to dust-plasma interaction in space environments and laboratory devices, is presented. The new research horizons (different new fields of physics involving many challenging research problems and open issues) introduced by this new physics of dust in plasmas are explained.

Charged Atmospheric Aerosols from Charged Saltating Dust Aggregates

open access: yesAtmosphere, 2023
Grain collisions in aeolian events, e.g., due to saltation, result in atmospheric aerosols. They may regularly be electrically charged, but individual charge balances in collisions including small grains are not easily obtained on the ground.

The outer dusty edge of accretion disks in active galactic nuclei

open access: yesFrontiers in Astronomy and Space Sciences, 2023
Recent models for the inner structure of active galactic nuclei (AGN) aim at connecting the outer region of the accretion disk with the broad-line region and dusty torus through a radiatively accelerated, dusty outflow.

Analysis of gamma-emitting radionuclides in soils around high energy accelerators

open access: yesRadiation Medicine and Protection, 2022
Objective: To investigate the specific activities of gamma radionuclides in the soils around high energy accelerators, and to analyze the influence of rays emitted by nuclides with characteristic peaks at similar energy points on nuclide measurement ...

Influence of multi-ion on the dust grain surface potential of complex plasmas using non-Maxwellian approach

open access: yesResults in Physics, 2021
Dust grain surface potential in multi-ion plasmas having two negative ions within the context of kappa-distributed dusty plasma is studied analytically and numerically.

Cometary dust analogues for physics experiments [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2022
ABSTRACT The CoPhyLab (Cometary Physics Laboratory) project is designed to study the physics of comets through a series of earth-based experiments. For these experiments, a dust analogue was created with physical properties comparable to those of the non-volatile dust found on comets.

Analyzing LDEX's Current Measurements in Lunar Orbit

open access: yesThe Planetary Science Journal, 2023
The Lunar Dust Experiment (LDEX) on board the Lunar Atmosphere and Dust Environment Explorer mission orbited the Moon from 2014 September to 2015 April and observed a dynamic, permanently present dust cloud produced by continual meteoroid bombardment. In
