Researchers at the George W. Woodruff School of Mechanical Engineering have developed a new approach to nanoscale 3D printing that improves both speed and fidelity, overcoming a challenge that has limited the technology's ...
A research team in China has reported a significant piezoelectric effect in ultrathin and ultra-flexible polycrystalline diamond membranes. This pioneering discovery challenges a century-long scientific dogma that diamonds ...
Piezoelectric materials, which convert mechanical stress into electricity and vice versa, are essential components in sensors, actuators, and energy-harvesting devices. However, the best piezoelectric materials, such as lead ...
Using atomic-scale defects in diamond, researchers in China have gained unprecedented insights into the complex chemical processes that unfold at the interfaces between solid surfaces and their surroundings. Published in ...
Controlled manipulation of fibers that are as thin as or even thinner than human hair is a real challenge. Despite technological development, the precise and reversible change of the microfibers' orientation is not easy. ...
At the heart of every camera is a sensor, whether that sensor is a collection of light-detecting pixels or a strip of 35-millimeter film. But what happens when you want to take a picture of something so small that the sensor ...
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 ...
