Persilylated and Related Silyl Anion‐Induced Synthesis of Group 3–10 Metal–Silyl Complexes

Chemistry – A European Journal, EarlyView.
Persilylated and related silyl anions serve as powerful tools for constructing metal–silyl complexes across group 3–10 elements. Their strong σ‐donating ability and steric bulk stabilize low‐coordinate, reactive species and enable unique bonding motifs.

Sm-Nd, Sr, C and O isotope systematics in hydrothermal calcite-fluorite veins: Implications for fluid-rock reaction and geochronology

, 2009
The 147Sm-143Nd isotope system may be used to determine the age of hydrothermal vein growth for single veins, or sets of veins, providing that the minerals in these veins formed from a hydrothermal fluid with initially homogeneous 143Nd/144Nd.

Carboxylate–Probase Catalyzed Favorskii Reaction

Chemistry – A European Journal, EarlyView.
Stronger together: A combination of a carboxylate catalyst and a silylating agent generates a stronger base catalyst for a metal‐free catalytic addition of alkynes to aldehydes and ketones under chemoselective, O‐silylative conditions. The reaction is proposed to proceed via quaternary ammonium (Q+) cation – acetylide anion ion pairs, with chiral ...

Peroxodisulfate‐Enhanced Leaching of Deep‐Sea Manganese Crusts and Sulfides

Chemie Ingenieur Technik, EarlyView.
Ammonium peroxodisulfate enables efficient leaching of deep‐sea manganese crusts and massive sulfides while offering electrolytic recycling. High leaching yields for V, Mn, Co, Mo, Sn, and W, along with complete leaching of As and Sb, highlight its potential as a powerful and sustainable oxidant for marine resource processing.

The Governance Gap: Democratizing Drug Development Through Decision Architecture

Clinical Pharmacology &Therapeutics, EarlyView.
Drug development is most exposed to governance failure where it can least afford it, in global health. The field has more predictive power than at any point in its history and roughly the same failure rate it had a decade ago. We argue that this paradox persists because the field has invested heavily in prediction science while neglecting decision ...
