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 ...
When accelerated neutrons or ions bombard a material, its surface layer undergoes dramatic physical and chemical transformations. The National Center for Nuclear Research in Swierk, Poland, has managed to learn in detail ...
Photonic thermometers—which measure temperature using light—have been around in optical fiber form for decades. These devices, called fiber Bragg gratings, are embedded in commercially available fibers thinner than a ...
To make sure our buildings and infrastructure are earthquake-safe, we must understand how seismic activity affects different structures. Miniature models and historical observations are helpful, but they only scratch the ...
In the American action movie "Pacific Rim," giant robots called "Jaegers" fight against unknown monsters to save mankind. These robots are equipped with artificial muscles that mimic real living bodies and defeat monsters ...
"Extraordinary claims require extraordinary evidence," said Carl Sagan. This phrase is the standard that astronomers will be applying to a curious signal captured with China's "Sky Eye" telescope that might be a transmission ...
It's been 50 years since humans first walked on the moon. Since then, astronauts have primarily explored low Earth orbit. Now that NASA is preparing to return to the moon, experts are reevaluating the practicality of the ...
Superconductors are materials that can enter a state of no electrical resistance, through which magnetic fields cannot penetrate. Due to their interesting properties, many material scientists and engineers have been exploring ...
Dielectric elastomer actuators (DEAs) can undergo large, reversible in-plane deformation. In a new report now published in Science Advances, Junhong Pu and a team of scientists in soft materials research and polymer science ...
For the first time, researchers have created a metasurface lens that uses a piezoelectric thin film to change focal length when a small voltage is applied. Because it is extremely compact and lightweight, the new lens could ...
