Summary: In this study, a series of transparent hybrid materials composed of organically modified titanium oxo-oligomers were prepared. The refractive index of the materials decreased with increasing organic content. Thermomechanical analysis revealed a glass transition near room temperature, and the softening temperature decreased with increasing organic content. Water-resistance properties were also reduced with increasing organic content. Hardness and elastic modulus showed no clear dependence on organic content.

Summary: In this study, we optimized the waveguide sensor both theoretically and experimentally to achieve sensitive detection of volatile toxic pyridine vapor with a detection limit in the parts per billion (ppb) range. The miniature sensor utilized a CMOS-compatible silicon nitride Mach-Zehnder interferometer waveguide with a dipolar polycarbonate as the sensitive cladding material. The thickness of the sensitive layer was found to be crucial for sensing sensitivity and response time. The achieved sensitivity for pyridine sensing was 63 pm/ppm, with a detection limit as low as 476 ppb. This research provides a simple and efficient strategy for sensitive detection of hazardous chemical vapors and has potential applications in biochemical sensing.
