TL;DR: In this article, a novel chitosan/titanium dioxide (CS/TiO2) nanocomposite membranes were prepared using tetrabutyl titanate (TBT) as precursor and acetyl acetone as chelating agent by in situ sol-gel process, and characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and thermogravimetry (TG).

TL;DR: In this paper, the pH-induced conformational transitions which occur with poly( l -lysines) of varying molecular weight were performed in aqueous media under conditions believed from previous CD studies to induce the polypeptide to adopt a particular type of secondary structure.

TL;DR: In this paper, the photocatalytic activity of sol−gel-derived TiO2 thin films by a simple treatment with trifluoroacetic acid (TFA) was investigated.
Abstract: Enhancement of the photocatalytic activity of sol−gel-derived TiO2 thin films by a simple treatment with trifluoroacetic acid (TFA) was investigated. The thin films were characterized with N2 adsorption, Fourier transform infrared spectroscopy, UV−visible spectroscopy, X-ray photoelectron spectroscopy, photoluminescence spectroscopy, X-ray diffraction, atomic force microscopy, and differential thermal analysis/thermogravimetry analysis. The photocatalytic activity of the thin films was evaluated by the photocatalytic decomposition of acetone in air. The results show that TFA is chemisorbed on the surface of the TiO2 films as a trifluoroacetate complex. The photocatalytic activity of modified TiO2 thin films is higher than that of unmodified TiO2 thin films, and the modified film treated at 250 °C shows the highest activity. This is ascribed to the fact that the TFA complex bound on the surface of TiO2 acts as an electron scavenger and, thus, reduces the recombination of photogenerated electrons and holes....
