Thermally stable films with ordered pores are fabricated from porphyrinated polyimides and they exhibit excellent property in HCl gas sensing.
Resistivity based sensing for the detection of 3 ppm SO2 gas by using LaFeO and LaCaFeO nanoparticle sensors.
Hierarchical ZnO hollow cubes constructed using Zn-based metal–organic frameworks enhance significantly chemical sensitivity towards low-concentration gaseous benzene.
A highly ordered 5,10,15,20-tetraphenylporphyrin doped poly(methyl methacrylate) nano-array was developed via a facile self-templating synthesis method, which improves the sensitivity of the HCl gas sensor to the ppm-level.
