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

open access: yesAdvanced 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 ...

Microbial Respiration, the Engine of Ocean Deoxygenation [PDF]

open access: yesFrontiers in Marine Science, 2019
Microbial plankton respiration is the key determinant in the balance between the storage of organic carbon in the oceans or its conversion to carbon dioxide with accompanying consumption of dissolved oxygen. Over the past 50 years, dissolved oxygen concentrations have decreased in many parts of the world’s oceans, and this trend of ocean deoxygenation ...

Bridging Horizontal to Vertical Radiative Cooling

open access: yesAdvanced Science, EarlyView.
Radiative cooling materials are mature but only work facing the sky, confining them to rooftops. Instead of developing new ones, this system bridges existing horizontal coolers to vertical windows using blades outside the glass. On an occupied urban building, windows stay up to 1.4°C below air temperature while preserving daylight, outward views, and ...

Photoactivation‐Enabled Tunable Room‐Temperature Phosphorescence and Thermally Activated Delayed Fluorescence in Crystalline Materials

open access: yesAdvanced Science, EarlyView.
This work is the first to demonstrate the regulation of photoactivated room‐temperature phosphorescence (RTP) and thermally activated delayed fluorescence (TADF) in crystalline materials without any pretreatment. Furthermore, we reveal the underlying mechanisms by uncovering the role of host‐guest energy level alignment, exciton lifetime, crystallinity,

A New Neural Network Framework Integrating Symbolic Computation to Solve the (2+1)-Dimensional Boussinesq Equation

open access: yesMathematics
The (2+1)-dimensional Boussinesq equation is a fundamental model in nonlinear wave theory, governing shallow-water wave propagation, coastal dynamics in ocean engineering, and long waves in geophysical fluid systems such as atmospheric and oceanic ...

Asymmetric Fluorinated Spiro Hole‐Transport Materials Enabled by a Rapid Core‐Forming Strategy for Blade‐Coated Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
Facile synthesis of asymmetric fluorinated spiro‐type HTMs combined with blade‐coating fabrication and vacuum‐assisted crystallization enables high‐efficiency PSCs with PCEs of 24.49% (0.09 cm2) and 23.28% (1.00 cm2), along with excellent stability.

Ammonification Process Is Limited by Transformation of Medium Molecular Weight Nitrogenous Organics but Not Hydrolysis of Proteins

open access: yesAdvanced Science, EarlyView.
A multi‐level analytical framework, integrating protein‐level persistence analysis, nontargeted HRMS formula tracking, peptide‐level proteomics, and targeted monomer quantification under varying redox conditions, together with FMO calculations reveal that ammonification is limited by medium molecular weight nitrogenous multimers.
