Since there is a causal link between the chemical structure and UV absorbance that is a prerequisite for photo-induced toxicity, the scientific rationale for a successful global model is obvious. An in silico tool, combined with UV spectra, has been developed with a high-quality database of approximately...

Thanks to their high polymerizability, low-shrinkage level, low-toxicity and low volatility, telechelic vinylether-based resins appear to be an attractive alternative to aerylate UV-cured systems suitable for various applications, and in particular as protective coatings. Moreover, a broad range of vinylether compounds are now commercially available. Indeed, in the past few years, thermal and photo-induced cationic crosslinking polymerization of simple eommercial divinylethers have been thoroughly studied in term of kineties and also from the viewpoint of materials properties. ... 

In the presence of O2 and H2O, the photo-formed e and h react with these molecules on the titanium oxide surfaces to produce 02/ and OH radicals, respectively. These 02/ and OH radicals have a very high oxidation potential, inducing the complete oxidation reaction of various organic compounds such as toxic halocarbons, as shown in... 

Such high photocatalytic reactivities of photo-formed e and h can be expected to induce various catalytic reactions to remove toxic compounds and can actually be applied for the reduction or elimination of polluted compounds in air such as NO cigarette smoke, as well as volatile compounds arising from various construction materials, oxidizing them into CO2. In water, such toxins as chloroalkenes, specifically trichloroethylene and tetrachloroethene, as well as dioxins can be completely degraded into CO2 and H2O. Such highly photocatalyti-...

The broad-spectrum biocidal action induced by phototoxic allelochemicals has been demonstrated toward a range of organisms including bacteria, fungi, nematodes, insects as well as non-photo-toxin-containing plants. Table III summarizes the organisms susceptible to photosensltlzatlon by alpha-terthienyl, a phototoxin characteristic of many Asteraceae species (4, 10-11). The toxicity of this thiophenic polyine toward plant pathogens (e.g.,...
