Combustion and Pyrolysis EA‐IRMS Techniques to Determine the δ2H of Diamonds

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.

Radon‐222 as an Effective Tracer to Distinguish Groundwater Circulation Patterns in the Deep Fault‐Controlled Geothermal System

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Groundwater flow regulated by deep faults remains challenging to trace due to structural complexity. This study applies the noble gas tracer 222Rn combined with hydrochemistry and stable isotopes (δ2H, δ18O) to distinguish circulation patterns of geothermal springs along a major fault in the Tibetan Plateau.

Unexpected Products Isolated From Neptunium Halide Syntheses

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 14, 14 May 2026.
Unanticipated products can crystallize when doing ligand substitution chemistry of NpCl4(DME)2 (DME = 1,2‐dimethoxyethane). Dissolution of NpCl4(DME)2 in CDCl3 can recrystallize the dimer [NpCl3(μ‐Cl)(DME)]2. The presence of hydroxylammonium from oxidation state adjustment can result in the isolation of (NH3OH)2[NpCl6]•3(1,4‐dioxane). The contamination

Inhibiting cGAS‐STING to Preserve Mitochondrial–Nuclear Communication and Stemness in Young Tendon Stem Cells: A Hydrogel Strategy against Age‐Related Tendinopathy

open access: yesAdvanced Science, Volume 13, Issue 26, 8 May 2026.
A dual‐targeting strategy to rejuvenate aged tendons. A reactive oxygen species (ROS)‐responsive hydrogel co‐delivers a selenium nanozyme (scavenges ROS) and a STING inhibitor to tendon stem cells. This combined action restores mitochondria–nucleus communication, alleviates cellular senescence, and rejuvenates tendon regeneration, offering a novel ...

MXenes: Bridging the Gap Between Advanced Materials and Sustainable Technologies in Energy and Environmental Applications

open access: yesAdvanced Electronic Materials, Volume 12, Issue 9, 11 May 2026.
MXenes, a family of two‐dimensional transition metal carbides and nitrides, exhibit exceptional physical and chemical properties tunable through surface functionalization. This review summarizes recent advances in MXene synthesis, property modulation, and composite fabrication.
