Sometimes friction is good, such as the friction between a road and a car's tires to prevent the vehicle from skidding. But sometimes friction is bad—if you did not put oil in that very same car, there would be so much ...
Lasers find applications across several fields ranging from telecommunications and remote sensing to medicine. There are many ways in which one can generate laser emission, or lasing, from a device or material. Consequently, ...
Today, lasers are well-established in daily life, even if it is sometimes hard to tell what and where they are. As an example, we can find them in CD/DVD readers or medical applications like cancer and eye surgery, being ...
In recent years, global digitalization has seen unprecedented acceleration. Video streaming and video conferencing in home office and remote learning settings has resulted in a spike in residential broadband usage. Emerging ...
An international group of researchers has measured how much a laser beam tugs on the water it shines through.
In a new report now published in Science Advances, Andrey Jarmola and an international research team in physics and materials in the U.S. and Germany demonstrated the function of a rotation sensor based on the Nitrogen-14 ...
Optical metasurfaces can unprecedently regulate versatile wavefronts at the subwavelength scale. Most well-established optical metasurfaces are, however, static and feature well-defined optical responses that are determined ...
Accelerometers in mobile phones, microprocessors in laptops, and gyroscopes that balance drones each rely on microelectromechanical systems, or MEMS for short. Within these small systems are even smaller devices, called actuators ...
Hydrodynamic cavitation is a major phase change phenomena that can occur with a sudden decrease in the local static pressure within a fluid. The emergence of microelectromechanical systems (MEMS) and high-speed microfluidic ...
Researchers have developed new X-ray optics that can be used to harness extremely fast pulses in a package that is significantly smaller and lighter than conventional devices used to modulate X-rays. The new optics are based ...
