Researchers from Chinese Academy of Sciences have prepared mesoporous hollow TiO₂ microspheres via a facile solvothermal method using glycine as a multifunctional smart template.

The glycine serves as a sacrificial template, complexing agent and water supplier in the TiO₂ microsphere synthesis and the cavity volume can be easily controlled by varying the mass of crude glycine used. Eu-doped TiO₂ hollow spheres have been made by this method and they exhibit stronger photoluminescence – due to their unique microstructures – compared to conventional, hydrothermal samples.

Researchers from University of Idaho have synthesized and characterized 4-(trifluoromethyl and pentafluorosulfanyl)-substituted mono- and poly-1,2,3-triazole compounds.

These triazoles can be obtained in moderate to good yield from Cu(I) catalyzed 1,3-dipolar cycloaddition reaction of various azides with trifluoromethyl- and pentafluorosulfanyl-substituted acetylenes. The fluorinated triazene-(1,2,3-triazole) compounds exhibit the best detonation properties – comparable to that of TNT – and all bar one of them have high thermal stability (>270 °C) and are insensitive to impact.
