This paper presents the design and development of a passive wireless sensor for the detection of bio-hazard materials and vapors using chemiresistive thin films. Composite polymer thin film with functionalized carbon nanotubes (f-CNT) and polymethylmethacrylate (PMMA) is employed as a sensing material. It is investigated that resistance change is determined with the concentration of dichloromet...
Thin-film electrodes for a low-power direct methanol fuel cell DMFC were prepared by incorporating carbon-supported Pt nanoparticles Pt/C into a silicon dioxide glass matrix. The SiO2 matrix was prepared via a sol-gel technique where tetraethyl orthosilicate TEOS was hydrolyzed by H2O in the presence of methanol. The Pt/C was stirred into the sol and the resulting mixture was applied to a glass...
