The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Water‐Derived Radical Species Initiate Six‐Electron Oxidation of Cyclic Ketones in Microdroplets
Angewandte Chemie, EarlyView.Spontaneous six‐electron oxidation of cyclic ketones to yield dicarboxylic acids/keto acids is achieved in ethanol microdroplets containing about 2% water under ambient conditions without any metal salts, acids, or oxidants. Mechanistic studies show that trace amounts of water and molecular oxygen serve as active oxidants in this transformation ...

The Complex Structure of Molten NaCl-CrCl3 Salt: Cr-Cl Octahedra Network and Intermediate-Range Order [PDF]
, 2020 The resurgence of the Molten-Salt Nuclear Reactors (MSR) creates interesting problems in molten-salt chemistry. As MSRs operate, the composition and physical properties of salts change because of fission and corrosion. Since Cr is the principal corrosion

Angewandte Chemie, EarlyView.Protic molecules containing strong O─H or N─H bonds typically resist hydrogen‐atom abstraction because of the high reactivity of the resulting heteroatom‐centered radicals. However, association of the protic molecules with redox‐active Lewis acids can provide powerful hydrogen‐atom donors or proton‐coupled‐electron‐transfer reagents.

Beyond-mean-field calculations of collectivities of neutron-rich Fe and Cr isotopes
, 2014 The rotational symmetry is broken in mean-field models. The symmetry breaking may lead to significant effects even on the ground states of nuclei. The recent observations of enhanced collectivities in neutron-rich Fe and Cr isotopes are challenging the ...

Feature Selection Techniques for CR Isotope Identification with the AMS-02 Experiment in Space
ParticlesIsotopic composition measurements of singly charged cosmic rays (CR) provide essential insights into CR transport in the Galaxy. The Alpha Magnetic Spectrometer (AMS-02) can identify singly charged isotopes up to about 10 GeV/n.

Angewandte Chemie, Volume 138, Issue 39, 21 September 2026.State‐of‐the‐art synthesis of radiolabelled oligonucleotides involves multi‐step synthesis with high costs, extended timelines and significant radioactive waste generation. Herein, a dual‐methyltransferase platform enables late‐stage, site‐specific labelling, overcoming these limitations through reduced costs, faster turnaround and minimal radioactive ...
