Abstract: In this article, a fiber-optic hydrogen sensor based on a cascaded Fabry–Perot interferometer (FPI) structure and vernier effect is proposed and experimented. The sensor is mainly composed ...

Castle Wonderland had one of the first fully-dimmable LED-lit rooms anywhere, when, in 2011, I made up 11 luminaires, each with an early 3W Cree led, and wired them in series for one of the ceilings ...

And right now the best wireless gaming mouse is the Razer Deathadder V3 HyperSpeed, thanks to its impeccable sensor, fantastic battery life, and significantly cheaper cost compared to the Pro.

Say goodbye to embarrassing parking mishaps. Whether you’re after added peace of mind during close-quarters maneuvering of your car or truck or you share a vehicle with a younger or less ...

(Photo: Mikael Nyberg) Nanotubes are often used to make hybrid sensors by combining them with another surfactant, but in this study the sensor was made completely from nanotubes. In addition, the ...

(Nanowerk Spotlight) Each exhaled breath carries distinct signatures of human activity - quick and shallow during exercise, deep and regular in sleep, irregular while speaking. These breathing ...

One important change is a new laptop battery indicator that visualizes the charge level with new symbols. This change was actually supposed to be implemented last month, but the release was ...

Scientists at The University of Manchester have unveiled a hydrogen ... and reversible at room temperature up to 120°C, making it ideal for real-world applications. The sensor has already been ...

The sensor operates using a process called p-doping, where oxygen molecules increase the concentration of positive electrical charges in the active material. When hydrogen is present, it reacts with ...

Splitting water molecules takes more energy than calculations suggest, and is a key roadblock to cheap hydrogen fuel production. Now, scientists have discovered why.
