Advanced Engineering Materials, EarlyView.Laboratory protocols for producing thin‐film pH electrodes for sterilized single‐use technologies have been successfully developed into a semiautomated workflow, with higher throughput and precision of membrane thickness. Accuracies are within 0.05 pH units versus ground truth, and uncertainty analysis reveals the largest sources of error to be derived

Separation of the natural retinoids by high-pressure liquid chromatography
Journal of Lipid Research, 1978 A reverse phase high-pressure liquid chromatography system for rapid separation of various retinoids (vitamin A and its analogs) with little or no degradation is described. This method permits detection of as little as 22 pmol of retinoic acid.

Advanced Functional Materials, EarlyView.Transarterial Chemoembolization (TACE) may aggravate liver fibrosis. In this study, a novel oral targeting nanoemulsion is fabricated to enhance the therapeutic effect of antifibrotic drug‐pirfenidone (PFD) on fibrosis after TACE. Studies have shown that PFD nanoemulsion can enhance the oral liver targeting effect of PFD, and effectively improve the ...

Advanced Functional Materials, EarlyView.In this work, a magnetic core‐shell catalyst (HOF‐on‐Fe3O4/ZIF‐67) is successfully synthesized, consisting of a metal–organic framework (ZIF‐67) with magnetic Fe3O4 as the core and a porous hydrogen‐bonded organic framework (HOF) as the shell. The catalyst efficiently activated peroxymonosulfate, resulting in rapid and effective removal of water ...
