Covalent Organic Frameworks for Photocatalytic CO2 Reduction: Metal Integration Principles, Strategies and Functions

Advanced Functional Materials, EarlyView.
Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.

2-Oxoesters: A Novel Class of Potent and Selective Inhibitors of Cytosolic Group IVA Phospholipase A2. [PDF]

, 2017
Cytosolic phospholipase A2 (GIVA cPLA2) is the only PLA2 that exhibits a marked preference for hydrolysis of arachidonic acid containing phospholipid substrates releasing free arachidonic acid and lysophospholipids and giving rise to the generation of ...

3D‐Printed Porous Hydroxyapatite Formed via Enzymatic Mineralization

Advanced Functional Materials, EarlyView.
Bone combines lightness, strength, and the ability to heal, inspiring new materials design. This work introduces a room‐temperature, enzyme‐mediated 3D printing method to create porous hydroxyapatite scaffolds. The process avoids energy‐intensive sintering, preserves bioactivity, and allows control over porosity and mineralization.

A Novel Synthetic Method for β-keto Esters

Journal of Chemical Research, 2007
A novel synthetic method for the preparation of β-keto esters has been developed. α-Phenylseleno acetate was treated with LDA to produce a selenium-stabilised carbanion, which reacted with aldehydes, followed by selenoxide syn-elimination, to give β-keto esters.

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)

Advanced Functional Materials, EarlyView.
Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

Preparation of cholesterol esters of long-chain fatty acids and characterization of cholesteryl arachidonate*

Journal of Lipid Research, 1962
Cholesterol esters of long-chain saturated fatty acids (C12 to C22), as well as those of the C18 unsaturated fatty acids (oleic, linoleic, and linolenic), were prepared by the ester interchange method, starting with cholesteryl acetate and the methyl ...

Deciphering Small Molecule Diffusion Parameters Across Light Responsive Polymersome Membranes

Advanced Functional Materials, EarlyView.
Light‐responsive polymersomes bearing donor–acceptor Stenhouse adducts (DASAs) enable programmable control over small‐molecule transport across synthetic membranes. By systematically varying DASA density, an optimal functionalization regime is identified that maximizes light‐gated permeability.

Mydriatic Activity of Some New Synthetic Anticholinergic Esters.

Experimental Biology and Medicine, 1947
SummaryThe β-diethylaminoethyl esters of di-α-thienyl-, diphenyl-, phenyl-a-thienyl-and cyclohexyl-α-thienylglycolic acids are anticholinergic drugs with significant mydriatic action. Of these, the cyclohexyl-α-thienylglycolic acid ester (No. 623) is the most mydriatic substance.
