Here is an example of one research abstract on the Promising Research Abstracts database. These films are very promising as new effective catalysts, magnetic and nonlinear optical films, elements of integrated chemical systems for electrochemical processes. Recently it was shown that on the base of such film's sensor, devices can be made for the detection of chemical compounds in the air. This application has substantial significance for environmental study and industrial use.
Sensoric effect depends on PbO content, structure of substrate, and other factors as well.
