Low Latency Global Carbon Budget Reveals Late 2024 Carbon Losses and Contrasting Early 2025 Land Sink Recovery Signals

Advanced Science, EarlyView.
Low latency carbon budget estimates for July 2024–June 2025 combine atmospheric CO2 growth rates, fossil emissions, ocean uptake, DGVM land fluxes, and OCO‐2 inversions. The budget shows that late‐2024 land carbon losses dominate the annual anomaly, while early‐2025 recovery differs between bottom‐up models and top‐down inversions, especially in ...

Nickel Intercalation in Epitaxial Graphene on SiC(0001): A Novel Platform for Engineering Two‐Dimensional Heterostructures

Advanced Science, EarlyView.
Ni‐intercalated graphene on SiC is achieved through a scalable colloidal nanoparticle deposition route. 2D heterostructures show preserved graphene band structure, stable under ambient conditions, and robust interfacial magnetism. Intercalated 2D Ni represents a promising candidate for next‐generation spintronic devices and is a scalable pathway to ...

A Very‐High Frequency Solution‐Processed Organic Field‐Effect Transistor With Improved Voltage‐Normalized Frequency of Transition

Advanced Science, EarlyView.
Increasing the frequency at which organic electronics operate while limiting the operation voltage is key to enabling future sustainable wireless applications. This work shows p‐type organic field‐effect transistors based on a molecularly doped, small molecule/polymer blend (C8‐BTBT:C16IDT‐BT), fabricated via direct‐writing and solution‐processing ...

Smaller Than Earth Habitability Model (STEHM): The Lower Size Limit for Atmosphere Retention in the Habitable Zone

The Planetary Science Journal
With recent advances in exoplanet observational techniques enabling the discovery of increasingly smaller planets, a crucial question emerges in the search for habitable planets: how small can a planet be and still maintain an atmosphere?

How leaky? A large parameter study of leaky dust traps to quantify the transport of pebbles and ice in protoplanetary discs

Astronomy & Astrophysics
In protoplanetary discs, the presence of dust traps can significantly alter the transport of solids from the outer to the inner regions, and hence they are often invoked as an explanation for the chemical diversity of inner discs observed with the James ...

Astronomers Find Planet with Similarities to Earth

Astronomers have found a new planet that is more like Earth than the other extrasolar planets found before, which were large and gaseous. This radio broadcast reports on this newly discovered planet, which appears to be small and rocky.

Dr. Art's Guide to Planet Earth

, 2000
This book explains the Earth system using three concepts: 1.The cycles of matter; 2.The flows of energy; and 3.The web of life. It then applies these concepts to real-life problems and issues that affect us and our planet.

Interfacial Tandem Catalysis Over a CuSn(OH)6/Co Heterostructure Enables Efficient Electroreduction of Nitrate to Ammonia

Advanced Science, EarlyView.
Interfacial tandem catalysis is developed for efficient electrochemical reduction of NO3− to NH3 over a CuSn(OH)6/Co heterostructure. CuSn(OH)6 accelerates the rate‐determining NO3−‐to‐*NO2 conversion, whereas Co promotes H2O dissociation to enhance *H supply for the rapid hydrogenation of *NO2 intermediate to NH3.
