State Key Laboratory for Quality Ensurance and Sustainable Use of Dao-di Herbs, National Resource Center for Chinese Materia Medica, China Academy of Chinese Medical Sciences Beijing 100700, China.
This study aims to identify the main chemical compounds, investigate the effects of different drying methods on the quality, and determine the appropriate drying method of Callicarpae Nudiflorae Folium. UPLC-UV-Q-TOF-MS was employed to characterize and identify 35 main compounds, including phenylethanoid glycosides, flavonoids, and iridoids in Callicarpae Nudiflorae Folium. A method for the simultaneous determination of 8 compounds with strong UV absorption and high content was established to evaluate the quality of Callicarpae Nudiflorae Folium dried by different methods.

IRCCS San Raffaele Scientific Institute, Experimental Imaging Center, Milan, Italy. Electronic address:
Purpose: Minibeam radiotherapy (MBRT) uses small parallel beams of radiation to create a highly modulated dose pattern. The aim of this study is to develop an optical radioluminescence imaging (RLI) approach to perform real-time dose measurement for MBRT.
Methods: MBRT was delivered using an image-guided small animal irradiator equipped with a custom collimator.
Radiation Damage Mitigation in FeCrAl Alloy at Sub-Recrystallization Temperatures.

Department of Mechanical Engineering, The Pennsylvania State University, University Park, PA 16803, USA.
Traditional defect recovery methods rely on high-temperature annealing, often exceeding 750 °C for FeCrAl. In this study, we introduce electron wind force (EWF)-assisted annealing as an alternative approach to mitigate irradiation-induced defects at significantly lower temperatures. FeCrAl samples irradiated with 5 MeV Zr ions at a dose of 10 cm were annealed using EWF at 250 °C for 60 s.
