Isolation and determination methods for brain cerebrosides, hydroxy fatty acids, and unsaturated and saturated fatty acids

Journal of Lipid Research, 1959
A new method is described for the isolation of nearly pure total cerebrosides from fresh brain. Florisil columns are used to separate the cerebroside hydroxy and normal acids, in the form of their esters, and to separate the saturated and unsaturated ...

A Hierarchically Structured, Stretchable, Anti‐Biofouling Encapsulation for Biodegradable Electronics

Advanced Healthcare Materials, EarlyView.
A soft, stretchable, anti‐biofouling encapsulant is developed by integrating organosilicon nanowire networks with microstructured biodegradable elastomers. The hierarchical surface exhibits superhydrophobicity and enhances water barrier properties by 420% over pristine polymers, while preserving mechanical integrity.

Unravelling the Atomic Structure of a Metal‐Covalent Organic Framework Assembled from Ruthenium Metalloligands

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
Metal‐covalent organic frameworks (MCOFs) are novel porous materials that exhibit the advantages of covalent and metal‐organic frameworks. However, it is extremely difficult to resolve their atomic structure and better understand their structure‐properties relation. This work utilizes a synergistic combination of advanced microscopy, spectroscopic, and
