The purpose of this study was to evaluate the histopathological effects of eugenol (EUG) and iso-eugenol (IsoEUG)--with or without visible light (VL) irradiation--on oral mucous membranes. Oral mucous membranes of mice were applied with three agents, EUG, IsoEUG, and aceton (as the control) in the absence or presence of VL irradiation. VL irradiation resulted in more tissue damage for EUG- or I...

Thermodynamical and optical properties of pure and electron beam irradiated (20, 80 and 100 kGy doses) liquid crystalline material cholesteryl pelargonate (nonanoate) have been investigated by differential scanning calorimeter, polarized light microscopy and ultraviolet-visible spectroscopy. Transition temperatures, enthalpies and entropies are found to be lowered due to the irradiation. A dono...

Nanostructured PbSnO(3) photocatalysts with particulate and tubular morphologies have been synthesized from a simple hydrothermal process. As-prepared samples were characterized by X-ray diffraction, Brunauer-Emmet-Teller surface area, transmission electron microscopy, and diffraction spectroscopy. The photoactivities of the PbSnO(3) nanostructures for isopropanol (IPA) degradation under visibl...

2,4,6-Triphenylpyrylium cation encapsulated within zeolite Y promotes highly selective transformation of olefins to ketones with molecular oxygen, under visible light (lambda > 400 nm) irradiation at room temperature.

Highly stable covalently attached multilayer films were constructed by visible-light irradiation of hydrogen-bonding directed multilayer films of poly(allylamine) and poly(4-vinylphenol).
