Geophysical Monograph Series, Page 263-304., 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.

Angewandte Chemie, EarlyView.We report a dual chemical looping/catalytic process coupling alkane dehydrogenation with aromatic alkylation over Cu‐mordenite, yielding up to 25% alkylated aromatics with >95% selectivity per cycle. In situ NMR, FTIR spectroscopy, and DFT show alkylation proceeds via a π‐bound Cu(I)–olefin intermediate and Brønsted acid sites.

Angewandte Chemie International Edition, EarlyView.Cu3P nanoparticles anchored on MXene via Ti─O─P bonds exhibit enhanced stability and resist agglomeration during the electrochemical semi‐hydrogenation of C2H2 to C2H4. Ti3C2/Cu3P achieves a record energy efficiency of 23.0% at 0.2 A cm−2 and stable operation in a 4 cm2 MEA for over 100 h at 1.0 A.
