Coccidiosis is a very contagious disease that may result in economic losses, especially in intensive farms.
The development of multi-residue methods that are able to determine regulated compounds is still quite challenging, owing to their different physicochemical properties and the LODs that have to be reached. LC-MS/MS is currently the most used technique for their determination in feed and food. To the best of our knowledge, these analytes have only been determined in three cases by means of HRMS. The present work was carried out to obtain fit for purpose LODs and the highest possible selectivity of a method for the determination of coccidiostats in eggs and muscle with LC-Q-Orbitrap, performing parallel reaction monitoring (PRM) acquisition for the first time. Moreover, a full validation study was carried out according to CIR (EU) 2021/808. View this paper
The improper disposal of retired lithium batteries will cause environmental pollution and a waste of resources. In this study, a waste lithium iron phosphate battery was used as a raw material, and cathode and metal materials in the battery were sepa...
A novel ZIF-8 assisted polyacrylamide functionalized silica polar stationary phase was prepared by a facile method of adding ZIF-8 nanoparticles and silica into polyacrylamide (PAM) aqueous solution, and then stirring the mixture until the solution w...
(1) Background: Edible plant-derived nanoparticles contain large amounts of endogenous substances and can be used as carriers for disease treatment. However, the extraction rate and purity are not high. Raphani Semen, the dried seed of the Raphanus s...
The co-occurrence of mycotoxigenic fungi and mycotoxins in aquatic food commodities has recently become a source of severe worldwide food insecurity since these toxicants may damage human health. The consumption of aquatic food itself represents a re...
Long-lived fissiogenic technetium, 99Tc (half-life, 2.11 × 105 yrs), is a byproduct of the 235U and 239Pu fission in nuclear reactors and is a major component in nuclear waste. Hence, the monitoring of 99Tc activity in the environmental samples is es...
Natural products serve as a valuable source of antioxidants with potential health benefits for various conditions. Lygodium microphyllum (Cav.) R. Br., also known as Old World climbing fern, is an invasive climbing fern native to Southeast Asia, Afri...
In this paper, the mechanism of separation of volatile organic compounds (VOCs) from activated carbon adsorption beds during closed cycle temperature swing desorption was studied. Toluene gas at different concentrations was used as the gas for closed...
Alternate pumping chromatography is applied to obtain atomically precise glutathione-stabilized gold nanoclusters in high purity from synthesized mixtures. On the basis of anion exchange chromatography, the feasibility of isolating a single cluster,...
Functional groups on support membranes are important for the preparation of high-performance membrane adsorbers (MAs). In this work, the effects of different functional groups on support membranes on the adsorption performance of MAs were studied thr...
The present study deals with the adsorptive removal of Escherichia coli (E. coli) by making use of chitosan-silica/calcium carbonate (CS-SiO2/CaCO3) nanocomposites (NCs) where it was synthesized using the waste eggshells and rice husks occurred by na...
