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.

Heterogeneous Ice Nucleation by Graphene Nanoparticles [PDF]

open access: yesScientific Reports, 2020
AbstractNanostructure, chemical composition and size distribution of aerosols have prime important effects on their efficiency in heterogeneous ice nucleation (HIN). The ice nucleation usually requires active sites in the aerosols in order to act as ice nuclei (IN).

Temperature-dependent kinetic pathways of heterogeneous ice nucleation competing between classical and non-classical nucleation

open access: yesNature Communications, 2021
Ice nucleation on the surface plays a vital role in diverse areas, ranging from physics and cryobiology to atmospheric science. Compared to ice nucleation in the bulk, the water-surface interactions present in heterogeneous ice nucleation complicate the ...

Investigating the effectiveness of condensation sink based on heterogeneous nucleation theory

open access: yes, 2020
New Particle Formation (NPF) is regularly observed to occur in heavily polluted Chinese megacities. However, in these NPF events, the survival probability of small clusters into larger aerosol particles is higher than theoretically predicted.

Harnessing heterogeneous nucleation to control tin orientations in electronic interconnections. [PDF]

open access: yesNat Commun, 2017
While many aspects of electronics manufacturing are controlled with great precision, the nucleation of tin in solder joints is currently left to chance.

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.

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

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 ...
