Subject:
Escherichia coli; Fourier transform infrared spectroscopy; Staphylococcus aureus; antimicrobial properties; aqueous solutions; cell membranes; chitosan; contact angle; crystal structure; electrostatic interactions; fluorescence; hydrogen bonding; hydrophilicity; melting point; nanofibers; physical properties; polyethylene glycol; thermal analysis
Abstract:
... In this study, chitosan/poly(ethylene oxide) (PEO)/lauric arginate (LAE) composite nanofibrous films were fabricated via electrospinning. The addition of LAE did not change the physical properties of chitosan/PEO in acetic aqueous solutions, but increased the fluorescent intensity of chitosan by electrostatic interactions, resulting in uniform and bead-free nanofibers with an average diameter of 1 ...

Abstract:
... Semisynthetic phenol derivatives were obtained from the natural phenols: thymol, carvacrol, eugenol, and guaiacol through catalytic oxychlorination, Williamson synthesis, and aromatic Claisen rearrangement. The compounds characterization was carried out by ¹H NMR, ¹³C NMR, and mass spectrometry. The natural phenols and their semisynthetic derivatives were tested for their antimicrobial activity ag ...
