Dynamic site‐interconversion reduces the induction period of methanol‐to‐olefin conversion

open access: yesAIChE Journal, EarlyView.
Abstract Reaction–diffusion coupling across the catalyst pore, grain, pellet, and reactor bed has been studied using a particle‐resolved transient microkinetic model applied to temperature‐programmed desorption and step‐response studies of methanol and dimethyl ether conversion over ZSM‐5 catalysts, respectively.

Coupling of CuO@NiBiOx Catalyzed Glycerol Oxidation to Carbon Dioxide Reduction Reaction for Enhanced Energy Efficiency

open access: yesAngewandte Chemie, EarlyView.
A CuOx@NiBiOx core‐shell‐like catalyst is synthesized. Thanks to the Bi presence, the electronic structure of Ni is tuned, leading to better catalytic performance for glycerol oxidation compared to both CuOx and CuOx@NiOx catalysts. Additionally, coupling glycerol oxidation with CO2 reduction significantly reduces the operational voltage and the ...

Site‐Selective Carbonylation of Azetidines via Copper‐Catalyzed Difluorocarbene Insertion

open access: yesAngewandte Chemie, EarlyView.
We disclose a site‐selective Cu‐catalyzed carbonylation of azetidines promoted by difluorocarbene insertion at low temperature, enabling access to a variety of functionalized γ‐lactams and a therapeutic agent for diabetes (40 examples). This skeletal expansion strategy provides a distinct disconnection approach to synthesize medicinally relevant five ...

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.

Production Of 11C‐Labeled Amides Via “In‐Loop” 11C‐Carbonylation

open access: yesAsian Journal of Organic Chemistry, EarlyView.
The current work utilizes carbon‐11 labelled aroyl dimethylaminopyridinium salts in a two‐step in‐loop carbonylative cross‐coupling reaction of aryl halides with [¹¹C]CO yielding a diverse range of carbon‐11 labelled primary benzamides with good to excellent yields.

Astaxanthin ameliorates benzalkonium chloride–induced dry eye disease through suppressing inflammation and oxidative stress via Keap1‐Nrf2/HO‐1 signaling pathways

open access: yesAnimal Models and Experimental Medicine, EarlyView.
The flowchart of this research. Abstract Background Dry eye disease (DED) predominantly results from elevated tear film osmolarity, which can not only cause ocular inconvenience but may lead to visual impairments, severely compromising patient well‐being and exerting substantial economic burdens as well.

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
