Sensitivity studies of dust ice nuclei effect on cirrus clouds with the Community Atmosphere Model CAM5 [PDF]

open access: yesAtmospheric Chemistry and Physics, 2012
In this study the effect of dust aerosol on upper tropospheric cirrus clouds through heterogeneous ice nucleation is investigated in the Community Atmospheric Model version 5 (CAM5) with two ice nucleation parameterizations.

Molecular simulations reveal that heterogeneous ice nucleation occurs at higher temperatures in water under capillary tension [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
Heterogeneous ice nucleation is thought to be the primary pathway for the formation of ice in mixed-phase clouds, with the number of active ice-nucleating particles (INPs) increasing rapidly with decreasing temperature.

On the ice nucleation spectrum [PDF]

open access: yesAtmospheric Chemistry and Physics, 2012
This work presents a novel formulation of the ice nucleation spectrum, i.e. the function relating the ice crystal concentration to cloud formation conditions and aerosol properties.

Formation of ice particles through nucleation in the mesosphere [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
Observations of polar mesospheric clouds have revealed the presence of solid ice particles in the upper mesosphere at high latitudes; however, their formation mechanism remains uncertain.

Heterogeneous formation of polar stratospheric clouds – Part 2: Nucleation of ice on synoptic scales [PDF]

open access: yesAtmospheric Chemistry and Physics, 2013
This paper provides compelling evidence for the importance of heterogeneous nucleation, likely on solid particles of meteoritic origin, and of small-scale temperature fluctuations, for the formation of ice particles in the Arctic stratosphere.

Manipulating Nucleation Potency of Substrates by Interfacial Segregation: An Overview

open access: yesMetals, 2022
During solidification of metallic materials, heterogeneous nucleation occurs on substrates, either endogenous or exogenous. The potency of the substrates for nucleation is mainly dependent upon the atomic arrangements on the substrate surface, which are ...

On the transition between heterogeneous and homogeneous freezing [PDF]

open access: yesAtmospheric Chemistry and Physics, 2003
Box model simulations of an uplifting and adiabatically cooling cloud of aerosol have been performed in order to study the transition between cirrus formation dominated by homogeneous nucleation of ice to that dominated by heterogeneous nucleation. The

Heterogeneous nucleation of protein crystals on fluorinated layered silicate. [PDF]

open access: yesPLoS ONE, 2011
Here, we describe an improved system for protein crystallization based on heterogeneous nucleation using fluorinated layered silicate. In addition, we also investigated the mechanism of nucleation on the silicate surface.

Study of the Immersion Freezing Theory Using the Classical Nucleation Framework

open access: yesAtmosphere, 2022
The classical nucleation theory for immersion freezing was used for the simulation of ice nuclei particle activation under atmospheric conditions. A modification of the surface diffusion energy was introduced that was based on the concept of a two ...
