Direct assessment of the proton affinity of individual surface hydroxyls with non-contact atomic force microscopy [PDF]
Nature 592, 2021, 722-725, 2023 The state of protonation/deprotonation of surfaces has far-ranging implications in all areas of chemistry: from acid-base catalysis$^1$ and the electro- and photocatalytic splitting of water$^2$, to the behavior of minerals$^3$ and biochemistry$^4$. The acidity of a molecule or a surface site is described by its proton affinity (PA) and pK$_\mathrm{a}$

Does the size distribution of mineral dust aerosols depend on the wind speed at emission? [PDF]
Kok, J. F. (2011), Does the size distribution of mineral dust
aerosols depend on the wind speed at emission?, Atmospheric Chemistry and
Physics, 11, 10149-10156, 2011, 2011 The size distribution of mineral dust aerosols partially determines their interactions with clouds, radiation, ecosystems, and other components of the Earth system. Several theoretical models predict that the dust size distribution depends on the wind speed at emission, with larger wind speeds predicted to produce smaller aerosols.

Enumerating the climate impact of disequilibrium in critical mineral supply [PDF]
arXiv, 2023 Recently proposed tailpipe emissions standards aim to significant increases in electric vehicle (EV) sales in the United States. Our work examines whether this increase is achievable given potential constraints in EV mineral supply chains. We estimate a model that reflects international sourcing rules, heterogeneity in the mineral intensity of ...

Photoprocessing of formamide ice: route towards prebiotic chemistry in space [PDF]
A&A 636, A63 (2020), 2020 Aims. Formamide (HCONH2) is the simplest molecule containing the peptide bond first detected in the gas phase in Orion-KL and SgrB2. In recent years, it has been observed in high temperature regions such as hot corinos, where thermal desorption is responsible for the sublimation of frozen mantles into the gas phase.

Geochemical and reflectance spectroscopy data integration to characterize emerald deposits: the case of the Paraná deposit, Brazil [PDF]
Anais da Academia Brasileira de Ciências, 2021 The Paraná emerald deposit is one of the few occurrences of emerald, a rare beryl variety, in Borborema Province, northeastern Brazil. We characterized the Paraná deposit by combining field geology, petrography, whole-rock geochemistry, mineral chemistry,
