A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

open access: yesAdvanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

Hierarchical Modeling of Solar System Planets with Isca

open access: yes, 2019
We describe the use of Isca for the hierarchical modeling of Solar System planets, with particular attention paid to Earth, Mars, and Jupiter. Isca is a modeling framework for the construction and use of models of planetary atmospheres at varying degrees

Revolutionising Agricultural Sustainability: New ‘Furrow Tillage’ can Mitigate Short‐Term Soil‐to‐Atmosphere CO2 Flux and Promote Soil‐Plant‐Microbe Health

open access: yesAdvanced Science, EarlyView.
Furrow tillage resolves the conventional‐vs.‐no‐tillage trade‐off by simultaneously cutting CO2 efflux to 2.0–3.0 g C m−2 d−1 and unlocking high nutrient availability for the rice rhizosphere. This scalable agronomic solution strengthens soil health, enhances plant physiology, reshapes microbial metabolism, and shifts paddy systems toward a net ...

A Sustainable Bio‐Based Epoxy Thermoset as a High‐Performance Alternative to BPA‐Based Resins

open access: yesAdvanced Science, EarlyView.
A rigid–flexible bio‐based epoxy network integrates soybean oil, lignin, and maleic anhydride to overcome the strength–toughness–sustainability trade‐off of conventional BPA epoxy. The thermoset delivers excellent performance as both a structural adhesive and a matrix for glass‐fabric composites, while enabling pH‐responsive degradation, environmental ...

An Evolving Cosmic Shoreline and Sandbar Bounding the Rocky Airless Valley

open access: yesThe Astrophysical Journal Letters
Recent JWST observations challenge the traditional “cosmic shoreline” from both sides, revealing thick volatile atmospheres on the hottest close-in “lava worlds,” where irradiation should drive the most extreme escape, and bare rocky surfaces on cooler ...

MgP4/CNT‐Graphene Embedded in Hard Carbon Matrix as a High‐Capacity Anode for Next‐Generation Sodium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
Phosphorus‐rich MgP4 is introduced as a high capacity anode for sodium‐ion batteries (SIBs) via hybrid carbon matrix engineering. A sequential CNT/G assembly forms a conductive and mechanically robust network, delivering a high reversible capacity of 1386 mAh g−1 while stabilizing alloying reactions.

Planetary atmospheres: Microwave spectroscopic and space physics [PDF]

open access: yes, 1990
Ground-based spectroscopic observations of isotopes of CO in the atmosphere of Mars, Venus, and Titan were collected over the 1982-1990 period. These observations were analyzed to obtain information on the photochemistry, dynamics, and thermal profiles ...

Covalently Integrated Selenoviologen–N‐Heterocyclic Carbene–Pt Nanoparticles for Visible‐Light‐Driven Hydrogen Evolution

open access: yesAdvanced Science, EarlyView.
A covalently integrated single‐component photocatalyst is constructed by anchoring selenoviologen to platinum nanoparticles via robust N‐heterocyclic carbene ligands. The resulting Pt─C covalent bonds function dually as protective structural scaffolds and direct channels for ultrafast intramolecular electron transfer This precise interfacial ...
