• protocol significantly, with the drawback of needing conventional heating at 100 °C for the composite material to activate the reacting carbonyl group by lowering its LUMO orbital, rendering it a more potent electrophile so that the nucleophilic indole can attack it (Scheme 16) [101][102]. Both aliphatic

Ray and Lalman deposited nanofiber TiO2 to a metal support via electrospinning a solution of titanium tetraisopropoxide and polyvinyl acetate (PVAc) to form a TiO2-PVAc composite material. TiO2-PVAc was subsequently
