Researchers have developed a new method for 3D printing objects with very different properties, including levels of hardness and transparency, on a pixel-by-pixel basis while using commonly available materials and inexpensive 3D printers. The method, […]
Inspired by electric rays that generate high voltages through stacked electrocytes, researchers at UNIST have developed a novel energy harvesting technology that mimics this biological mechanism. Unlike electric rays, which require mechanical stimulation, this new […]
Power sources used in devices found in or around biological tissue must be flexible and nontoxic, while still powerful enough to support demanding technologies such as medical devices or soft robotics. To achieve this balance, […]
From subarctic to subtropical, Japan’s varied climates present a challenge for energy-saving housing design. Adding the projected effects of climate change, with temperatures estimated to rise from 1.5 to 3.5°C by the close of the […]
Perovskite solar cells (PSCs) are known for their impressive ability to convert sunlight into energy, their low production costs and their lightweight design. They may well be the rising stars of renewable energy, but they […]
Concrete structures like roads and bridges require nondestructive testing methods to identify interior defects without destroying their structure. Most methods send sound waves into the material and capture the waves that echo back to create […]
More than a century after the Titanic sank, engineers still have hopes of someday creating “unsinkable” ships. In a step toward reaching that lofty goal, researchers at the University of Rochester’s Institute of Optics have […]
Organic semiconductors are thin, flexible, and extremely versatile materials that have revolutionized the world of consumer electronics. They are the core technology behind organic light-emitting diode (OLED) displays, which deliver the vivid colors and contrast […]
A research team at The Hong Kong Polytechnic University (PolyU) has developed a simple and affordable hydrogel coating that not only enhances the heat dissipation in solar panels for cooling their “hot spots” effectively, but […]
Detecting concealed explosives and chemical threats constitutes a critical challenge in global security, yet current technologies often face significant operational limitations. While X-ray scanners and millimeter-wave imaging can efficiently identify suspicious shapes, they frequently lack […]
