Fentanyl-sniffing sensor outperforms dogs at border, detecting airborne drugs in seconds with pinpoint accuracy.

Avalanche photodiodes (APDs) for ultra-sensitive infrared detection at eye-safe wavelengths are built around compound ...

Wearable conducting polymer-based NH3 sensors are highly desirable in real-time environmental monitoring and human health protection but still a challenge for their relatively long response/recovery ...

The Meter Pro from SwitchBot is so easy to use, and will keep me updated on firework smoke, air hazards and more.

Ahh, summer, a time of vacations at the beach or mountains—and sky-high electricity bills as your air conditioner labors ...

Terahertz radiation (THz), electromagnetic radiation with frequencies ranging between 0.1 and 10 THz, could be leveraged to ...

A photonic crystal fiber (PCF)-model interferometer (MI)-based relative humidity (RH) sensor is proposed and experimentally demonstrated. The PCF-MI is formed by fusion splicing a short length of PCF ...
