TL;DR: In this paper, the mechanistic steps responsible for the gas-induced conductance changes of polycrystalline metal-oxide sensors have been investigated and a suitable operating temperature, sensitivity, response and recovery time of the TiO2 thin film gas sensor was studied for sensing ammonia.

TL;DR: Structural investigations confirmed that the synthesized nanorods are single crystalline with the wurtzite hexagonal phase and preferentially grow along the c-axis direction and the clear observation of free excitons at low temperatures indicates that the as-grown ZnO nanorod are of high quality.

TL;DR: In this article, aluminum-doped zinc oxide (ZnO:Al), one of the promising TCOs, was prepared by radio frequency (RF) magnetron sputtering on glass (Corning 1737) substrates as a function of the deposition condition Argon gas pressure during deposition was kept in the range 004-133 Pa, and the temperature was maintained in between 300 and 673 K.

TL;DR: Alumina shell formation on TiO 2 core nanoparticles by atomic layer deposition (ALD) is studied to suppress the recombination of charge carriers generated in a dye-sensitized solar cell as mentioned in this paper.

TL;DR: A qualitative study on adhesion of the oral bacteria Porphyromonas gingivalis on titanium (Ti), titanium nitride (TiN), fluorine modified hydroxyapatite (FHA), and zinc modified FHA (Zn-FHA) thin films is investigated in this paper.
