Editorial: science and engineering, two aspects of materials

and air pollutants are very important. In one article screen printed electrodes (SPEs) for gas sensors which are based on polymer/carbon nanostructures (multi wall carbon nanotubes and grapheme) were modified by polymers such as conductive polymer Poly Vinylidene Fluoride and biocompatible Poly Ethylene Glycol. The modified sensor electrodes exhibited excellent electrical properties, characterized by high conductivity and great potential application in the field of gas pollutants detection. In another article, Graphite oxide (GO) was used to anchor [PdCl2(TDA)2] and [RhCl(TDA)3] (TDA =NH2(CH2)12CH3) with 2wt% of metal load. The test results showed that [RhCl(TDA)3]/ GO was the best catalyst due to electronic and steric effects as well as the influence of the support.
