A Universal Approach to Anchoring Chromophores onto Magnetic Scaffold for Achieving Easily Recyclable Heterogeneous Photocatalytic Systems

open access: yesAdvanced Science, EarlyView.
The practical application of chromophores such as porphyrins, coumarins, anthraquinones, and pyrene derivatives in photocatalysis is severely limited by catalyst stability and reusability. In this work, a simple and universal strategy is presented for preparing highly efficient and recyclable heterogeneous photocatalysts for the oxidative coupling of ...

Mapping of the \u3cem\u3eSaccharomyces cerevisiae\u3c/em\u3e Oxa1-Mitochondrial Ribosome Interface and Identification of MrpL40, a Ribosomal Protein in Close Proximity to Oxa1 and Critical for Oxidative Phosphorylation Complex Assembly [PDF]

open access: yes, 2009
The Oxa1 protein plays a central role in facilitating the cotranslational insertion of the nascent polypeptide chains into the mitochondrial inner membrane. Mitochondrially encoded proteins are synthesized on matrix-localized ribosomes which are tethered

CXCL6 Reshapes Lipid Metabolism and Induces Neutrophil Extracellular Trap Formation in Cholangiocarcinoma Progression and Immunotherapy Resistance

open access: yesAdvanced Science, EarlyView.
CXCL6's function in cholangiocarcinoma is underexplored. Here it is discovered that CXCL6 is upregulated in cholangiocarcinoma tissues and promotes proliferation and metastasis of it. CXCL6 functions through the CXCR1/2‐JAK‐STAT/PI3K axis and reshaping tumor lipid metabolism.

Hydrolyzable Bio‐Based Bisphenols Enabled by the Tishchenko Reaction for Polyurethane Vitrimers with Closed‐Loop Recyclability

open access: yesAdvanced Science, EarlyView.
This study employs the Tishchenko coupling reaction to obtain bio‐based bisphenols containing degradable ester bonds with 100% atom utilization. Based on these bio‐based bisphenols, a fully bio‐based polyurethane Covalent Adaptable Networks are constructed, while simultaneously endowing the material with closed‐loop recyclability, degradability, and ...
