Disentangling Partial Melting and Crustal Recycling Signatures in Ocean Island Basalts With Multivariate Statistics

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract Ocean island basalts (OIB) provide valuable constraints on mass exchange between the mantle and crust. When appropriate compositional data transformations are applied, multivariate analyses of OIB compositions can be used to infer mantle source heterogeneity and elucidate its driving processes.

Random walk on sphere packings and Delaunay triangulations in arbitrary dimension

open access: yesProceedings of the London Mathematical Society, Volume 131, Issue 3, September 2025.
Abstract We prove that random walks on a family of tilings of d$d$‐dimensional Euclidean space, with a canonical choice of conductances, converge to Brownian motion modulo time parameterization. This class of tilings includes Delaunay triangulations (the dual of Voronoi tessellations) and sphere packings.

Phosphazene Base Mediated (sp3)CH Functionalization with CO2 and CS2

open access: yesEuropean Journal of Inorganic Chemistry, Volume 28, Issue 24, August 29, 2025.
Selective deprotonation of HCF3, HC2F5, and CH3CN by the phosphazene base EtP4 in the presence of CO2 or CS2 affords the phosphazenium carboxylates [EtP4H]+[F3CCO2]− and [EtP4H]+[F5C2CO2]−, as well as the corresponding dithiocarboxylates [EtP4H]+[F3CCS2]− and [EtP4H]+[F5C2CS2]−.
