Prior heterogeneous ice nucleation events shape homogeneous freezing during the evolution of synoptic cirrus [PDF]

Atmospheric Chemistry and Physics
In situ observations are currently used to classify synoptic cirrus as formed by homogeneous or heterogeneous ice nucleation based on ice residual analysis.

Volume nucleation rates for homogeneous freezing in supercooled water microdroplets: results from a combined experimental and modelling approach [PDF]

Atmospheric Chemistry and Physics, 2010
Temperature-dependent volume nucleation rate coefficients for supercooled water droplets, <i>J_V(T</i>), are derived from infrared extinction measurements in a cryogenic laminar aerosol flow tube using a microphysical ...

Nonisothermal homogeneous nucleation [PDF]

The Journal of Chemical Physics, 1992
Classical homogeneous nucleation theory is extended to nonisothermal conditions through simultaneous cluster mass and energy balances. The transient nucleation of water vapor following a sudden increase in saturation ratio is studied by numerically solving the coupled mass and energy balance equations.

Homogeneous nucleation in associated vapors. II. Formic and propanoic acids [PDF]

, 1978
Homogeneous nucleation measurements have been made on formic and propanoic acids. The temperature dependence of the critical supersaturation was measured and found to agree well with that predicted by the Katz–Saltsburg–Reiss theory for nucleation in ...

Thermal Cycle–Microstructure–Property Relationships in Rail Steel Heat‐Affected Zone Simulated by Gleeble

Advanced Engineering Materials, EarlyView.
Microstructural evolution of premium rail steel during flash butt welding (FBW), comparing physically simulated heat‐affected zones with actual weld regions. Thermal cycles induce phase transformations and microstructural heterogeneity that influence weld quality and mechanical performance. These findings provide insights into optimizing FBW parameters

Microstructural, Mechanical, and Textural Evolution of Dissimilar Combination of Laser‐Welded Maraging Steel and 4340 Steel

Advanced Engineering Materials, EarlyView.
The present work reports the microstructural, mechanical, and texture evolution of a dissimilar combination laser‐welded maraging steel with 4340 steel. This is important for aerospace applications. The demand for dissimilar welding is growing rapidly with the requirement of efficient and durable joints.

Constraining a Radiative Transfer Model with Satellite Retrievals: Contrasts between cirrus formed via homogeneous and heterogeneous freezing and their implications for cirrus cloud thinning [PDF]

Atmospheric Chemistry and Physics
The efficacy of the climate intervention method known as cirrus cloud thinning (CCT) is difficult to evaluate in climate models, largely due to uncertainties governing the relative contributions of homogeneous and heterogeneous ice nucleation.

Propensity Rule in Homogeneous Nucleation Processes

, 1988
A linear relation is discovered between 1n J and 1/T (where J is the nucleation rate at temperature T in K) for homogeneous nucleation from the analysis of experimental data and is explained for water nucleation on the basis of classical nucleation ...

Spatially Regulated Lithium Plating via Li2O‐Rich Interphase Enables Durable Fast‐Charging Hybrid Lithium Batteries

Advanced Functional Materials, EarlyView.
A Li2O‐rich solid electrolyte interphase (SEI) is engineered on graphite through a propylene carbonate‐based electrolyte to spatially regulate Li plating. The homogeneous interphase lowers Li nucleation barriers, promotes conformal Li deposition around graphite particles, and suppresses dendritic accumulation, enabling durable hybrid Li‐ion/Li‐metal ...
