The Damhus Hoard: New Insights Into Some of the Earliest Viking Silver Coinage

Archaeometry, Volume 68, Issue S4, Page S71-S85, July 2026.
ABSTRACT In 2018, a hoard totalling 266 silver Viking Age coins was discovered near Damhus, south of Ribe (Denmark). The coins belong to the early ninth‐century ‘KG 4’ series, with the vast majority, 262 coins, identified as having Face/Forward Looking Deer on the obverse/reverse.

Commentary: Reframing Massive Carbon Input During the PETM and a Grand 66 Million Year Geoscience Puzzle

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Despite decades of research, hundreds of peer‐reviewed papers, and considerable relevance to Earth's future, the rapid global warming and tremendous CO2 input at the start of the Paleocene‐Eocene Thermal Maximum (PETM) remain highly debated.

Solar‐Driven Ammonia Synthesis From Nitrate Reduction Paired With CO2 Capture for Sustainable Agriculture via a Robust CuPd Heterojunction

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Laser‐assisted synthesis of CuPd amorphous/crystalline heterojunction demonstrates >80% Faradaic efficiency for nitrate‐to‐ammonia electroreduction across wide potential windows. The integrated solar‐powered electrolyzer achieves 6% solar‐to‐ammonia energy efficiency at 0.4 sun, 6–20 mg h−1 CO2 capture rate, and stability exceeding 100 h.

Thermal and Photocatalytic Conversion of CO2 to Ethanol: Advances in Catalyst Design, Challenges, and Opportunities

ChemSusChem, Volume 19, Issue 12, 26 June 2026.
This review examines thermo‐ and photocatalytic routes for converting CO2 to ethanol and analyzes how metal alloying, promoters, supports, surface structure, and semiconductor design govern catalyst activity, selectivity, and stability. It integrates mechanistic insights from experimental and theoretical studies and identifies the main challenges and ...

An Electron‐Poor Nickel Diphosphine Complex: Synthesis, Structure, and Reactivity of Ni(dFppe)2

Chemistry – A European Journal, Volume 32, Issue 24, 23 June 2026.
Fluorinated diphosphine ligands such as 1,2‐bis[bis(pentafluorophenyl)phosphino]ethane (dFppe) offer powerful electronic tunability and unusual reactivity. Despite known analogues of the heavier congeners Pd and Pt, Ni complexes of dFppe remain conspicuously absent.

Electroreductive Desulfurization of Thioacetals

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
A metal‐free electrochemical protocol enabled desulfurization of thioacetals under ambient conditions. Aryl substituents on sulfur act as internal electroauxiliaries to promote C(sp3)─S bond cleavage via a radical pathway, effectively serving as alternative to the Mozingo reduction.

Anthropogenic Carbon Isotope Signals in North Atlantic Water Masses at 48°N

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Deep‐water masses are formed in the North‐Atlantic, making studies of δ13C of dissolved CO2 in this region key to monitor and understand the spreading of anthropogenic carbon into the ocean interior. The objective of this study is to quantify the Suess effect (SE) in North Atlantic water masses using sulfur hexafluoride (SF6) as the ...
