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.

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.

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.

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 ...

Heterogeneous Nucleation of Ice on Carbon Surfaces

open access: yesJournal of the American Chemical Society, 2014
Atmospheric aerosols can promote the heterogeneous nucleation of ice, impacting the radiative properties of clouds and Earth's climate. The experimental investigation of heterogeneous freezing of water droplets by carbonaceous particles reveals widespread ice freezing temperatures.

Freezing nucleation apparatus puts new slant on study of biological ice nucleators in precipitation [PDF]

open access: yes, 2014
For decades, drop-freezing instruments have contributed to a better understanding of biological ice nucleation and its likely implications for cloud and precipitation development. Yet, current instruments have limitations.

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
