Heterogeneous formation of polar stratospheric clouds – Part 2: Nucleation of ice on synoptic scales [PDF]
Atmospheric 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
Metals, 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]
Atmospheric 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]
PLoS 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
Atmosphere, 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 ...

Efficiency of immersion mode ice nucleation on surrogates of mineral dust [PDF]
Atmospheric Chemistry and Physics, 2007 A differential scanning calorimeter (DSC) was used to explore heterogeneous ice nucleation of emulsified aqueous suspensions of two Arizona test dust (ATD) samples with particle diameters of nominally 0–3 and 0–7 μm, respectively ...

On the thermodynamic and kinetic aspects of immersion ice nucleation [PDF]
Atmospheric Chemistry and Physics, 2018 Heterogeneous ice nucleation initiated by particles immersed within droplets is likely the main pathway of ice formation in the atmosphere. Theoretical models commonly used to describe this process assume that it mimics ice formation from the vapor ...

Synergistic effects of Y and Nd on grain refinement of Mg-Y-Nd-Al alloy
Materials Research Express, 2022 In this study, the synergistic effects of Y and Nd on the grain refinement of the as-cast Mg-Y-Nd-Al alloy was investigated by varying Y and Nd contents while fixing their total content (Y + Nd) at 7%.

Molecular Oncology, EarlyView.This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.
