Liquid petroleum gas sensor based on SnO2/Pd composite films deposited on Si/SiO2 substrates
TL;DR: In this paper, the authors synthesized SnO 2 /Pd composite films by d.c. sputtering of a target followed by thermal evaporation of a thin layer of Pd on top of it.

Ni-doped vertically aligned zinc oxide nanorods prepared by hybrid wet chemical route
TL;DR: Ni-doped zinc oxide (Ni:ZnO) nanorods were synthesized by incorporating nickel in vertically aligned ZnO nanorod as discussed by the authors, and the optical band gap decreased with increasing amount of Ni incorporation and the origin of the photoluminescence peak at ∼400nm was related to the defect levels introduced due to substitution of Ni 2+ in the Zn 2+ site with annealing.
