Dynamic Cu^(I)/Cu^(II) Redox Shuttle for Maltose and Lactose Isomerization under Pulsed Electric Field

ACS Sustainable Chemistry & Engineering, Journal Year: 2024, Volume and Issue: 12(16), P. 6232 - 6241

Published: April 9, 2024

Due to their prebiotic effects, lactulose and maltulose have garnered increasing interest from the food pharmaceutical industries. Pulsed electric field (PEF) technology can enhance energy use efficiency, particularly in electroactivation, offering a potential means convert reducing sugars. A specialized PEF-treated design has been developed facilitate alternative catalyst-driven production of by manipulating morphology oxidation states copper catalysts. Under optimal conditions (4 kV/cm, 50 Hz, 10 μs for 30 min), remarkable yields (55.75%) (43.27%) were achieved. Higher conversion rates observed with an increased PEF treatment strength pulse width. The selectivities not significantly influenced frequency. Intriguingly, structural monosaccharides, including glucose, galactose, xylose, arabinose, also detected isomerization reaction. These findings suggest that PEF, utilizing CuO plates, induces glycoside bond hydrolysis aldose pentose. Microscopic measurements (high-resolution transmission electron microscopy (HRTEM), high-energy X-ray diffraction (XRD), situ Raman, photoelectron spectroscopy (XPS)) revealed transient Lewis acid–base pairs formed Cu+/Cu2+ shuttle could serve as active sites sugar isomerization, DFT simulation further confirmed presence Cu species promote lactose maltose via lower barrier. process proves be economical method transforming low-value sugars into high-value carbon materials.

Effects of Pulsed Electric Fields on the Elimination of Fusarium oxysporum in Greenhouse Soil

Agriculture, Journal Year: 2024, Volume and Issue: 14(12), P. 2158 - 2158

Published: Nov. 27, 2024

In greenhouses, high humidity, low light, and inadequate ventilation conditions, along with continuous high-density planting, promote the proliferation of soilborne pathogens. Among these pathogens, Fusarium oxysporum Schltdl (F. oxysporum) is a notably challenging one, causing root rot tomato plants in greenhouse cultivation. To address this issue, study applied pulsed electric field (PEF) to target elimination F. suspension soil media. Initially, PEF parameters were systematically explored suspensions determine effective ranges for oxysporum. The results revealed that achieving desired microbial reduction an strength (EFS) between 5–15 kV·cm−1, pulse number within range 100–500, width 10–20 µs. Subsequently, impact moisture content, bulk density, type on dielectric breakdown was analyzed from previous results. Based findings, experiments conducted designed prevent breakdown. Specifically, sampling content 16.2% density 1.31 g·cm−3, maximum application 9.5 accompanied by 1000 pulses 20 Finally, building results, samples sterilized parameter spanned 5–9.5 Response surface methodology (RSM) analysis further identified optimal combination: 8.2 306 pulses, 15 µs, resulting average lethal rate 76.16% sterilization soil. These findings suggest potential use against other pathogens soils, provide theoretical foundations experiments, thereby contributing sustainable advancement agriculture.
