Hot embossing and thermal bonding of poly(methyl methacrylate) microfluidic chips using positive Temperature Coefficient ceramic heater
Analytical and Bioanalytical Chemistry, 2011Co-Authors: Xia Wang, Luyan Zhang, Gang ChenAbstract:As a self-regulating heating device, positive Temperature Coefficient ceramic heater was employed for hot embossing and thermal bonding of poly(methyl methacrylate) microfluidic chip because it supplied constant-Temperature heating without electrical control circuits. To emboss a channel plate, a piece of poly(methyl methacrylate) plate was sandwiched between a template and a microscopic glass slide on a positive Temperature Coefficient ceramic heater. All the assembled components were pressed between two elastic press heads of a spring-driven press while a voltage was applied to the heater for 10 min. Subsequently, the embossed poly(methyl methacrylate) plate bearing negative relief of channel networks was bonded with a piece of poly(methyl methacrylate) cover sheet to obtain a complete microchip using a positive Temperature Coefficient ceramic heater and a spring-driven press. High quality microfluidic chips fabricated by using the novel embossing/bonding device were successfully applied in the electrophoretic separation of three cations. Positive Temperature Coefficient ceramic heater indicates great promise for the low-cost production of poly(methyl methacrylate) microchips and should find wide applications in the fabrication of other thermoplastic polymer microfluidic devices.

New negative Temperature Coefficient ceramics in Ca0.9Y0.1MoO4–CeNbO4 system
Materials Letters, 2020Co-Authors: Yafei Liu, Bo Zhang, Aimin ChangAbstract:Abstract The Ca0.9Y0.1CeNbMoO8 compounds are the solid solutions of Ca0.9Y0.1MoO4 and CeNbO4, and have a potential in the high Temperature thermistor application. A concept has been proposed to adjust the negative Temperature Coefficient (NTC) properties of these thermistors by increasing the content of CeNbO4. The structure of as-sintered Ca0.9Y0.1MoO4–xCeNbO4 ceramics is a single Ca0.9Y0.1MoO4 phase at x
