Gas-liquid chromatographic analyses of 1,2-ethanediol monoethers and monoesters

Journal of Lipid Research, 1968
Synthetic mixtures of saturated and unsaturated monoethers and monoesters of 1,2-ethanediol, ranging in chain length from 12 to 20, were analyzed as acetates, trifluoroacetates (TFA), and trimethylsilyl (TMS) ethers by gas chromatography on polar and ...

Diastereo-divergent synthesis of chiral hindered ethers via a synergistic calcium(II)/gold(I) catalyzed cascade hydration/1,4-addition reaction

Nature Communications
Hindered ethers are ubiquitous in natural products and bioactive molecules. However, developing an efficient method for the stereocontrolled synthesis of all stereoisomers of chiral hindered ethers is highly desirable but challenging.

Negotiating in a Foreign Land: Understanding the Curious Interactions Between Intracellular Mitochondria and Internalized Nanoparticles

Advanced Materials Interfaces, EarlyView.
Therapeutic nano‐drug delivery systems interact with cellular mitochondria in a multitude of ways. While the complexity of such interactions disrupts the mitochondrial electron transport chain and increases reactive oxygen species production, thereby contributing to nanoparticle toxicity, they also present unique theranostic opportunities in diseases ...

Al2O3 Ring Array by Infiltration Synthesis in Polystyrene Antidot Template

Advanced Materials Interfaces, EarlyView.
Different morphologies, such as full dots for genuine PS‐b‐PMMA, residual dots for the PS antidot array (resulting from an Acetic Acid (AA) last PS‐b‐PMMA), and rings for the modified PS antidot array (derived from an O2 plasma last PS‐b‐PMMA), originated from SIS process in PS‐b‐PMMA BCP array, due to the different reaction sites for the TMA precursor

Oxygen-doped carbon-supported palladium nanoparticles boost the tandem hydrogenation–acetalization–hydrogenolysis of phenols and diphenyl ethers to cyclohexyl ethers

Nature Communications
The one-pot hydrotreatment of phenols to cyclohexyl ethers is crucial but difficult to achieve for fine chemical synthesis owing to the easy overhydrogenation to cyclohexanols over traditional metal–acid bifunctional catalysts.

Surface‐Anchored Microgel‐Based Films as Anti‐Icing Coatings

Advanced Materials Interfaces, EarlyView.
The microgel‐based anti‐icing coatings presented in this work reduce ice adhesion by up to 90% on various substrates. This effect can be attributed to the incorporated functional cationic moieties binding a lubricating layer of quasi‐liquid interfacial water.
