Far-ultraviolet spectrophotometry of SPICA
The Astrophysical Journal, 1989 A spectrum of the star Spica (Alpha Virginis) from 960 to 1270 A was recorded by a rocket-borne spectrograph March 13, 1988. The spectrum, which has 3.4 A resolution, shows a much sharper drop-off in intensity near 1050 A than similar measurements made by the Voyager UVS, but is in good agreement with the spectrum obtained by Brune et al.

Screening of wheat grains enriched with wall-bound phenolic compounds
MethodsX, 2023 Phenolic compounds are dominant antioxidant factors in whole grains and are essential quality traits in future breeding programs. We proposed a robust set of methods for extraction, screening, and quantitative analysis of soluble and wall-bound (WB ...

Advanced Sensor Research, EarlyView.This study presents a novel strategy for the detection of polyphenols in wine. By combining Quartz Crystal Microbalance with Dissipation Monitoring and original functionalization strategies, Gelatin A from porcine skin and Mouse Proline‐Rich Protein 5, polyphenols are successfully detected directly in wine without any prior sample preparation ...

A Supramolecular Material for Controlling Kiwifruit Bacterial Canker
Advanced Science, EarlyView.The matrine‐5‐methylsalicylic acid salt (MOS) is reported for its excellent antibacterial activity against Pseudomonas syringae pv. actinidiae (Psa), with advanced cell membrane penetration ability and strong affinities for potential targets. Furthermore, a nanosupramolecular delivery system MOS@hydroxypropyl‐beta‐cyclodextrin (HPCD) with improved ...

Angewandte Chemie, EarlyView.Xanthopinacol (xpin) boronates are a conceptually new class of masked boronic acids designed to alleviate many of the disadvantages of pinacol esters and other popular adducts. They can be formed directly from xanthone and UV light, undergo orthogonal transformations, and are cleavable under photoredox catalysis or oxidative conditions that recycle ...
