Strontium titanate was once used as a diamond substitute in jewelry before less fragile alternatives emerged in the 1970s. Now, researchers have explored some of its more unusual properties, which might someday be useful ...
Researchers have developed an extremely thin, flexible imager that could be useful for noninvasively acquiring images from inside the body. The new technology could one day enable early and precise disease detection, providing ...
Microelectromechanical system (MEMS) optical modulators are crucial in next-generation technologies such as free-space optical communication and LiDAR, but existing designs struggle with balancing aperture size, efficiency, ...
Opaque materials can transmit light when excited by a high-intensity laser beam. This process, known as optical bleaching, induces a nonlinear effect that temporarily alters the properties of a material. Remarkably, when ...
Just a few years ago, researchers discovered that changing the angle between two layers of graphene, an atom-thick sheet of carbon, also changed the material's electronic and optical properties. They then learned that a "twist" ...
Classical theories of fatigue damage in bulk metals have been extensively studied, but little is known about the fundamental fatigue mechanisms at submicron and nanometer scales, where dislocation pattern formation is completely ...
The so-called Casimir force or Casimir effect is a quantum mechanical phenomenon resulting from fluctuations in the electromagnetic field between two conducting or dielectric surfaces that are a short distance apart. Studies ...
Research teams led by Prof. Zeng Changgan and Zhang Hui from the Hefei National Laboratory for Â鶹ÒùÔºical Sciences at the Microscale, the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences ...
Lighting a gas grill, getting an ultrasound, using an ultrasonic toothbrush—these actions involve the use of materials that can translate an electric voltage into a change in shape and vice versa.
The demand for microelectromechanical systems (MEMS) resilient to harsh environments is growing. Silicon-based MEMS struggle under extreme conditions, limited by their performance at elevated temperatures. Silicon carbide ...
