Summary: A highly linear temperature sensor based on a silicon carbide (SiC) p-n diode is introduced in this work. The diode shows excellent linearity in response to temperature from room temperature to 600℃ under a constant current biasing. The best linearity is achieved at a current density of 0.53 mA/cm(2), with a coefficient of determination R-2 of 99.98%. The sensor is compatible with Fraunhofer Institute (FHG) IISB's open SiC CMOS technology, allowing for monolithic integration with SiC readout circuits for high-temperature applications. This sensor is the first SiC diode temperature sensor that does not require a mesa etch or backside contacts.

Summary: This study presents a longitudinal flight dynamics study of a low mass moment of inertia vehicle. Aerodynamic and stability derivatives of a flying-wing microaerial vehicle (FWMAV) were obtained through wind tunnel tests, and a novel methodology for the estimation of dimensional derivatives is proposed. The results show that this methodology provides a more realistic representation of the longitudinal flight modes up to 89 degrees, whereas the conventional methodology is effective up to 57 degrees.

Summary: With the development of Lab on a chip technology, fluid management using dispersed droplets has become an important approach. Electrowetting on dielectric (EWOD) is one method for droplet actuation, but it requires prior definition of droplet positions. Optoelectrowetting (OEW) goes further by allowing changes in electrical parameters through impinging light spots, without the need for predefined droplet positions. This study re-evaluates the key parameters of OEW and explores their effects on droplet actuation using numerical optimization methods.

Summary: Recent studies have shown that two-dimensional Janus transition metal dichalcogenides (TMDs) have great potential for applications in gas sensors. By conducting first principles calculations, this study explores the potential application of Pd-doped monolayer HfSeS as gas sensor materials for detecting CO, CO2, NH3, and NO. The results demonstrate the good thermodynamical stability and reversible adsorption of these molecules on both pristine and Pd-doped HfSeS, with Pd-doped HfSeS showing higher sensitivity towards NO due to its metallic behavior upon NO adsorption.
