Elimination of massive aggregation of nanoparticles in the sample of high ionic strength is a prerequisite for the sensitive analysis through a surface-enhanced Raman spectrometry (SERS).We present a system of silver colloid modification composed of two thiolated modifiers (3-mercaptopropionic acid and thiolated polyethylene glycol) both creating a
In this study, three varieties of sorghum (Hongyingzi, Lunuo 18, and Liangnuo 1), which vary in quality, were used to brew jiang-flavor base baijiu.The differences in the physicochemical factors of fermented grains here and the important flavor compounds of base liquor from different rounds of fermentation were compared among the varieties.The resu
This study explores the application of artificial intelligence, specifically ChatGPT-4o, in constructing and managing a portfolio of cybersecurity stocks over the period from Q1 2018 to Q1 2024.Leveraging advanced machine learning models, fundamental analysis, sentiment analysis, and optimization techniques, the AI-driven portfolio significantly ou
ABSTRACT In this study, an IncI1 plasmid encoding resistance to both cefotaxime and azithromycin was recovered from a clinical Klebsiella pneumoniae strain.The azithromycin resistance was confirmed to be mediated by the erm(B) gene.This plasmid could be readily conjugated to strains of Escherichia coli and Salmonella, promoting rapid dissemination
