Ultrathin 2D In2O3 Nanosheets Confining Cu Single Atoms Synergized With Oxygen Vacancies for High Selectivity of Photocatalytic Reduction of CO2 to CO

Advanced Science, EarlyView.
In this work, we constructed an ultrathin two‐dimensional (2D) In2O3 nanosheet (In2O3‐Ns) structure based on oxygen vacancies (OV)‐rich defects and low crystallinity to anchor Cu single atoms (Cu SAs) and synthesized Cu/In2O3‐Ns photocatalysts. ABSTRACT In this work, we constructed an ultrathin two‐dimensional (2D) In2O3 nanosheet (In2O3‐Ns) structure ...

Methane emissions from canals draining tropical peatlands: Constraining temporal variability and emissions pathways

Limnology and Oceanography Letters
Drainage canals are potential hotspots of methane (CH4) emissions from degraded peatlands in Southeast Asia. Estimates of CH4 emissions from these canals remain scarce, and both the temporal variability and pathways of CH4 emissions are uncertain.

CO2 injection into submarine sediments: disturbing news for methane-rich hydrates [PDF]

, 2011
The production of natural gas via injection of fossil-fuel derived CO2 into submarine gas hydrate reservoirs can be an example of tapping a hydrocarbon energy source in a CO2-neutral manner.

Ablation‐Immune Thermal Armor Via Microstructural‐Compatibility Design for Extreme Thermal Conditions

Advanced Science, EarlyView.
This study unveils a microstructural‐compatibility design strategy that integrates reactive melt infiltration with plasma spraying to fabricate carbon fiber‐reinforced ZrC‐SiC composites. The deliberate incorporation of SiC into the ZrC coating releases heat accumulation, suppresses detrimental lamellar ZrO2 formation, and reduces residual stress. This

Temperature‐Modulated MEMS Gas Sensor Array Enabled by Physics‐Informed Deep Learning for Thermal‐Runaway Characteristic Gas Discrimination

Advanced Science, EarlyView.
This work presents a 2 × 2 integrated single‐chip MEMS gas sensor array with temperature modulation and deep learning for discriminating thermal‐runaway characteristic gases. The array generates distinct temperature‐modulated response patterns for four characteristic gases (H2, CO, CH4, and CO2), while a HK‐MoE model is developed to achieve robust ...

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

Advanced 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.
