In recent years, molecular materials exhibiting circularly polarized luminescence (CPL)—light with a specific rotational direction (right- or left-handed)—have attracted considerable attention for ...

Learn how to make your very own drone with our step-by-step guide to building a quadcopter! Whether you're a hobbyist or a ...

First person view (FPV) quadcopter drones have become increasingly more capable over the years, as well as much smaller. The ...

The build's extreme compactness limits its practical use – without landing gear or shielding, takeoff and recovery require precision and care – but its technical ingenuity ...

Perhaps the most surprising thing about shadowgraphs is how simple they are: you simply take a point source of light, pass the light through a the volume of air to be imaged, and record the pattern ...

Abstract: Aerial-aquatic locomotion would allow a broad array of tasks in robot-enabled environmental monitoring or disaster management. One of the most significant challenges of aerial-aquatic ...

Abstract: Accurate estimation of propellers rotation rate is crucial for effective radar classification of drones and provides valuable information into their capabilities. This paper presents two ...
