MEMS-based batch fabrication compatible sol–gel synthesized mesoporous nanocrystalline SnO 2 gas sensor has been developed. The SnO 2 nanofilm is fabricated with the combination of polymeric sol–gel chemistry and block copolymers used as structure directing agents. The novel hydrogen sensor has a fast response time (2 s) and quick recovery time (10 s), as(More)
Composite made of multiwalled carbon nanotubes coated with silver was fabricated by an electroless deposition process. The thickness of silver layer is about 40 to 60 nm, characterized as nano-crystalline with (111) crystal orientation along the nanotube's axial direction. The characterization of silver/carbon nanotube [Ag/CNT] nanowire has shown the large(More)
