Molecular simulations of heterogeneous ice nucleation. I. Controlling ice nucleation through surface hydrophilicity [PDF]
The Journal of Chemical Physics, 2015 Ice formation is one of the most common and important processes on earth and almost always occurs at the surface of a material. A basic understanding of how the physicochemical properties of a material’s surface affect its ability to form ice has remained elusive.

Ice nucleation properties of fine ash particles from the Eyjafjallajökull eruption in April 2010 [PDF]
Atmospheric Chemistry and Physics, 2011 During the eruption of the Eyjafjallajökull volcano in the south of Iceland in April/May 2010, about 40 Tg of ash mass were emitted into the atmosphere.

Biomolecules, 2022 The classical nucleation theory shows that bulk water freezing does not occur at temperatures above ≈ −30 °C, and that at higher temperatures ice nucleation requires the presence of some ice-binding surfaces.

Heterogeneous Ice Nucleation by Graphene Nanoparticles [PDF]
Scientific 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).

Packaging of Macroscopic Material Payloads: Needs, Challenges, Concepts, and Future Directions
Advanced Engineering Materials, EarlyView.This review introduces a unified framework that decomposes any macroscopic packaging system into the payload, packaging material, and packaging strategy and combines them into a conceptual packaging equation: packaging strategy = payload + packaging material.

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)
Advanced Functional Materials, EarlyView.Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

Effect of photochemical ageing on the ice nucleation properties of diesel and wood burning particles [PDF]
Atmospheric Chemistry and Physics, 2013 A measurement campaign (IMBALANCE) conducted in 2009 was aimed at characterizing the physical and chemical properties of freshly emitted and photochemically aged combustion particles emitted from a log wood burner and diesel vehicles: a EURO3 Opel Astra ...

Identification of a New Ice-nucleating Bacterium and Its Ice Nucleation Properties
Agricultural and Biological Chemistry, 1990 A new ice-nucleating bacterium, KUEN-3, was isolated from strawberry leaves. The ice-nucleating bacterium was found in the pale yellow colony group. Strain KUEN-3 was identified as Erwinia uredovora from its taxonomical characteristics. When strain KUIN-3 was cultured aerobically in a medium consisting of Simmons-citric acid broth (pH 6.1) for 24hr at ...
