Exploring ultrasound-induced free radical formation: A comparative study in water and sour cherry juice using glutathione and terephthalic acid indicators.

This study aims to assess free radical (FR) generation potential of ultrasound in water and sour cherry juice (SCJ) model systems using an indirect method with specific indicators including glutathione (GSH), a well-known antioxidant, and terephthalic acid (TPA), which fluoresces upon oxidation. Initially, aqueous GSH solutions were subjected to ultrasound at varying amplitudes (60 % and 80 %) for up to 30 min using probes of different diameters (13 mm and 19 mm) to identify maximal oxidation conditions. FR formation was monitored using UPLC equipped with diode array detector and fluorescence spectrophotometer for GSH and TPA oxidation, respectively.

Physicochemical and Antioxidant Properties of Industrial Hemp Seed Protein Isolate Treated by High-Intensity Ultrasound.

Ultrasound is one of the non-thermal, green, and novel technologies used to functionalize plant proteins. We recently determined the optimum conditions of high-intensity ultrasound (HIUS) treatment for maximum solubility and investigated the functional properties of hemp seed protein isolate (HSPI) under the optimal conditions. In this study, we analyzed changes in primary, secondary, and tertiary structures, physical microstructures, thermal stability, and antioxidant capacity of ultrasound-applied hemp protein isolate (HSPI-HIUS).

Sulfur doped LiAlTi(PO) solid electrolytes with enhanced ionic conductivity and a reduced activation energy barrier.

Recently, tailored synthesis of solid electrolytes satisfy multiple challenges, i.e. high ionic conductivity and wide (electro)chemical stability window is of great interest.
