Mitochondria‐Targeting Iron–Carbon Nanozymes Combat Hepatic Ischemia–Reperfusion Injury via the Dual Mechanisms of Respiratory Chain Remodeling and Pyroptosis Inhibition With MRI Monitoring

Advanced Science, EarlyView.
A mitochondrial‐targeted FeCD‐SS31 nanoplatform integrates ROS‐responsive SS31 release with cascade antioxidant Fe3O4/CDs cores to suppress both de novo and existing ROS. By restoring mitochondrial complex integrity and blocking caspase‐1–GSDMD‐N pyroptosis, it reduces neutrophil infiltration and alleviates hepatic ischemia–reperfusion injury, while ...

CO, CO2 and H2 adsorption on ZnO, CeO2, and ZnO/CeO2 surfaces: DFT simulations

Journal of Molecular Modeling, 2014
The adsorption of the molecules CO, CO2, and H2 on several ceria and zinc oxide surfaces was studied by means of periodical DFT calculations and compared with infrared frequency data. The stable CeO2(111), CeO2(331), and ZnO(0001) perfect faces were the first substrates considered. Afterwards, the same surfaces with oxygen vacancies and a ZnO monolayer

Influence of CeO2 on NOx emission during iron ore sintering

, 2009
The evolution of NOx during coke combustion in the presence and absence of CeO2 was studied in a quartz fixed bed reactor. The distribution of CeO2 in the coke was examined by SEM.

Size effect of Au nanoparticles in Au/CeO2 catalysts

, 2009
Au/CeO2 catalysts are widely reported to be highly active for CO oxidation and water gas shift (WGS) reactions, but the intrinsic active site as well as reaction pathway is still controversial.

To Be or Not to Be Eutectic: Anomalous Glass Forming Ability Governed by Melt Structural Complexity

Advanced Science, EarlyView.
Challenging the eutectic rule, congruently melting Ti–Cu alloys show greater glass‐forming ability than their eutectic counterparts. This arises from the congruent melt's structural complexity: higher cluster diversity and stronger inter‐cluster correlations from entropy–enthalpy competition.
