In Situ/Operando Probing of Dynamic Phase Structures of Alumina‐Supported Ultrasmall Copper‐Gold Alloy Nanoparticles Under Reaction Conditions

open access: yesAngewandte Chemie, EarlyView.
Supported ultrasmall copper‐gold alloy nanoparticles are active heterogenous catalysts. In situ TEM tracking under oxygen at different temperatures reveals atomic‐scale dynamic phase structures, whereas combined operando synchrotron HE‐XRD and DRIFTS characterizations uncover ensemble‐averaged ordering/disordering phase structures and oscillatory ...

R‐APEX: A Knowledge Graph–Based Platform for the Elucidation of the Toxicological Mechanisms of Ambient Particulate Matter

open access: yesAdvanced Intelligent Systems, EarlyView.
R‐APEX is a knowledge graph platform developed to investigate how air pollutants such as particularly fine particulate matter (PM2.5) affect human health. By integrating large‐scale biomedical data and using machine learning, it reveals pollutant–gene–disease associations.

Selective Electrochemical Production of Ethylene from Bicarbonate Solution

open access: yesAngewandte Chemie, EarlyView.
We report direct electroreduction of bicarbonate to C2+ products using Cu mesh catalysts. The effect of mesh thickness, pore size, catholyte composition, and thermal treatment was systematically studied. Our finding shows that thinner Cu mesh showed enhanced C2+ selectivity due to improved mass transport, while heat‐treated meshes form oxide‐derived ...

A Retrospective Analysis of Circular Economy and Industrial Decarbonization Metrics in the United States, 1998–2022

open access: yesJournal of Advanced Manufacturing and Processing, EarlyView.
Over two decades of emissions data are analyzed alongside economic indicators for 18 U.S. manufacturing industries. A retrospective analysis highlights interconnectedness (and in some cases, competition) between industrial growth, decarbonization, and materials circularity.

Potential Application of a Water‐Soluble Fullerene C60 Decorated with Diethylene Glycol in Treatment of Osteoarthritis

open access: yesAdvanced NanoBiomed Research, EarlyView.
A new ethoxyethanol derivative of iminofullerene, F2, is synthesized and labeled with 99mTc to produce 99mTc‐F2. In vitro, compound F2 inhibits the activation of primary mouse bone marrow‐derived macrophages stimulated with lipopolysaccharide. Moreover, 99mTc‐F2 is selectively enriched in the injured joints of mice. Inflammatory macrophages play a role
