In Situ Structural Evolution and Activity Descriptor of Atomically Dispersed Catalysts During Nitrate Electroreduction

Advanced Science, EarlyView.
The in situ evolution of single‐atom catalysts to metallic nanoclusters during nitrate electroreduction is demonstrated. A direct correlation between the OH binding energy on the metallic clusters and ammonia production rate is established as a key activity descriptor, explaining the superior performance of Ni and Co catalysts.

Carbon isotopes in environmental and palaeoclimate investigation [PDF]

, 2013
Natural cosmic-ray produced radiocarbon 14C is a part of the CO2 cycle and through the atmosphere-biosphere-hydrosphere exchange process has been introduced to the environment. Anthropogenic disturbance of the natural 14C activity caused by nuclear tests, nuclear power plants and fossil fuel combustion has been recorded in the atmospheric CO2.

SLC6A14 Drives Mitochondrial Fusion and Oxidative Phosphorylation to Promote Cancer Stemness and Early‐Onset of Breast Cancer

Advanced Science, EarlyView.
Elevated levels of the plasticizer DEHP associate with earlier breast cancer diagnosis. DEHP enhances glutamine‐powered energy production via the transporter SLC6A14 and pushes mitochondria toward fusion, driving tumor initiation by boosting cancer stemness. Blocking SLC6A14 lowers stemness, slows tumors, and improves chemotherapy response.

Strong Internal Electric Field‐Driven S‐scheme CoAl‐LDH/ZrO2 Heterojunction for Enhanced Photocatalytic CO2 Reduction: Configuration, Performance, and Mechanism

Advanced Science, EarlyView.
This study constructed an S‐scheme heterojunction catalyst CoAl‐LDH/ZrO2 driven by an internal electric field. The S‐scheme heterojunction accelerated charge separation and strengthened redox capability synergistically contribute to the superior CO2 reduction performance.Under simulated solar irradiation, optimal catalyst exhibited a CO production rate
