Heterogeneity in homogeneous nucleation from billion-atom molecular dynamics simulation of solidification of pure metal [PDF]

open access: yesNature Communications, 2017
Nucleation is a fundamental physical process, however it is a long-standing issue whether completely homogeneous nucleation can occur. Here the authors reveal, via a billion-atom molecular dynamics simulation, that local heterogeneity exists during ...

Direct calculation of ice homogeneous nucleation rate for a molecular model of water. [PDF]

open access: yesProc Natl Acad Sci U S A, 2015
Significance Despite the importance of ice nucleation in a wide range of natural and technological systems, it is not trivial to predict its kinetics or unravel its mechanism experimentally.

Homogeneous nucleation and microstructure evolution in million-atom molecular dynamics simulation. [PDF]

open access: yesSci Rep, 2015
Homogeneous nucleation from an undercooled iron melt is investigated by the statistical sampling of million-atom molecular dynamics (MD) simulations performed on a graphics processing unit (GPU).

Effect of cloud‐scale vertical velocity on the contribution of homogeneous nucleation to cirrus formation and radiative forcing

open access: yesGeophysical Research Letters, 2016
Ice nucleation is a critical process for the ice crystal formation in cirrus clouds. The relative contribution of homogeneous nucleation versus heterogeneous nucleation to cirrus formation differs between measurements and predictions from general ...

Effect of gravity wave temperature fluctuations on homogeneous ice nucleation in the tropical tropopause layer [PDF]

open access: yesAtmospheric Chemistry and Physics, 2016
The impact of high-frequency fluctuations of temperature on homogeneous nucleation of ice crystals in the vicinity of the tropical tropopause is investigated using a bin microphysics scheme for air parcels.

Anti‐Icing Organogel Enables Quasi‐Homogeneous Supercooling Preservation of Mouse Hearts [PDF]

open access: yesAdvanced Science
Supercooling preservation holds great promise for extending the storage limits of organs. However, supercooled systems are susceptible to stochastic ice nucleation, which can cause fatal damage to the organs.

Homogeneous ice nucleation in an ab initio machine-learning model of water [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2022
Significance Until recently, simulating ice nucleation with quantum accuracy was deemed impossible due to the prohibitive computational cost of quantum-mechanical calculations.

Experimental investigation of homogeneous nucleation of water in various gases using an expansion chamber [PDF]

open access: yesEPJ Web of Conferences, 2022
Nucleation is an integral part of phase transitions and plays an important role in technology. The control of nucleation in devices such as turbines, rocket and jet engines, wind tunnels, and combustion processes is key to achieving efficient ...

Studies on the Competition Between Homogeneous and Heterogeneous Ice Nucleation in Cirrus Formation

open access: yesJournal of Geophysical Research: Atmospheres, 2022
Cirrus ice crystals are produced heterogeneously on ice‐nucleating particles (INPs) and homogeneously in supercooled liquid solution droplets. They grow by uptake of water molecules from the ice‐supersaturated vapor.

The analysis of the nucleation process of the lithium germanium phosphate glass [PDF]

open access: yesScience of Sintering, 2022
The nucleation process of lithium germanium-phosphate glass was studied to determine the temperature range of nucleation and the temperature of the maximum nucleation rate.
