Ultra-sensitive ethanol detection using a chemiresistive SnO2 thin-film gas sensor functionalized with RuO2 nanosheets Open
This study presents the design and fabrication of a ruthenium dioxide (RuO2) nanosheets-functionalized tin dioxide (SnO2) thin-film gas sensor integrated with a microheater in a suspended membrane structure. The RuO2 nanosheets are synthes…

Fabrication of fine-pored polydimethylsiloxane using an isopropyl alcohol and water mixture for adjustable mechanical, optical, and thermal properties Open
A fabrication method for obtaining fine-pored PDMS is presented. Low-cost, volatile, and easily accessible IPA is used as a co-solvent in water and PDMS emulsions, allowing porous PDMS with adjustable mechanical, optical and thermal proper…
