Rapid increase in atmospheric iodine levels in the North Atlantic since the mid-20th century

open access: yesNature Communications, 2018
Despite its chemical importance, the evolution of atmospheric iodine concentrations over time is unknown. Here, the authors show that North Atlantic atmospheric iodine levels have tripled since 1950, and propose ozone pollution and enhanced biological ...

The chemistry of scrapie infection: implications of the ‘ice 9’ metaphor

open access: yesChemistry & Biology, 1995
The transmissible spongiform encephalopathies pose an increasing problem for animal, and perhaps human, health. The infectious agent seems to lack a nucleic acid component, posing the question of how it can reproduce. A model of reproduction by nucleated polymerization suggests a number of novel approaches to the problem.

Interfacial Ice Density Fluctuations Inform Surface Ice-philicity

open access: yes
The propensity of a surface to nucleate ice or bind to ice is governed by its ice-philicity — its relative preference for ice over liquid water. However, the relationship between the features of a surface and its ice-philicity is not well understood, and

Global Distribution and Seasonality of Martian Atmospheric HCl Explained Through Heterogeneous Chemistry

open access: yesGeophysical Research Letters
Recent observations from the ExoMars Trace Gas Orbiter (TGO) have revealed the presence of hydrogen chloride (HCl) in the martian atmosphere. HCl shows strong seasonality, primarily appearing during Mars' perihelion period before decreasing faster than ...

The End of Ice I

open access: yes, 2019
The appearance of ice I in the smallest possible clusters and the nature of its phase coexistence with liquid water could not thus far be unravelled.
