New Sulfur Amino Acids Findings Reported from Isfahan University of Technology [Novel chiral poly(amide-imide)/surface modified SiO2 nanocomposites based on N-trimellitylimido-L-methionine: Synthesis and a morphological study]

By a News Reporter-Staff News Editor at Life Science Weekly -- New research on Sulfur Amino Acids is the subject of a report. According to news reporting out of Esfahan, Iran, by NewsRx editors, research stated, "In the present investigation, novel poly(amide-imide) (PAI)/SiO2 nanocomposites (NCs) containing L-methionine moiety in the main chain were prepared via a simple and fast ultrasonic irradiation process. PAI was synthesized by direct poly condensation reaction of N-trimellitylimido-L-methionine with 4,4'-diamino diphenylether in molten tetra-n-butyl ammonium bromide/triphenyl phosphite as a green condensing agent."

Our news journalists obtained a quote from the research from the Isfahan University of Technology, "Due to the high surface energy and tendency for agglomeration, the surface of SiO2 NPs was modified with chiral diacid. The obtained NCs were characterized by Fourier transform-infrared (FTIR) spectroscopy, thermogravimetry analysis, X-ray powder diffraction, field emission-scanning electron microscopy (FE-SEM), and transmission electron microscopy (TEM). The FT-IR spectroscopy indicated that the chiral diacid as the coupling agent was attached on the surface of SiO2 NPs."

According to the news editors, the research concluded: "FE-SEM, and TEM images showed that SiO2 NPs were dispersed rather homogeneously in the PAI matrix."
