““Thermogalvanic Hydrogel for Synchronous Evaporative Cooling and Low-Grade Heat Energy Harvesting” Nano Letters Using electronic devices for too long can cause them to overheat, which might slow them down, damage their components or even make them explode or catch fire …
“Refreshable braille displays translate information from computer screens into raised characters, often along the bottom of a keyboard. But this technology can cost thousands of dollars and is limited, typically displaying a string of characters much shorter than most sentences …
“Flexible temporary electronic displays may one day make it possible to sport a glowing tattoo or check a reading, like that of a stopwatch, directly on the skin. In its current form, however, this technology generally depends on plastic. New …
““Detecting and Directing Single Molecule Binding Events on H-Si(100) with Application to Ultradense Data Storage” ACS Nano As computers continue to infiltrate almost every aspect of modern life, their negative impact on the environment grows. According to recent estimates …
“To seamlessly integrate electronics with the natural world, materials are needed that are both stretchable and degradable –– for example, flexible medical devices that conform to the surfaces of internal organs, but that dissolve and disappear when no longer needed. However …
“Imagine a runner who doesn’t need to carry a stopwatch or cell phone to check her time: She could just gaze at the glowing stopwatch display on the back of her hand. Such human-machine interfaces are no longer science …
“Batteries power most of our devices, and even some cars. But researchers now report in ACS Applied Materials & Interfaces a step toward running electronic devices in homes and offices on the light coming from lamps scattered around the room. The …
“In the quest to replace fossil fuels, scientists are always on the lookout for alternative, environmentally friendly sources of energy. But who could have imagined a bionic mushroom that produces electricity? It sounds like something straight out of Alice in …
“Electric vehicles and most electronic devices, such as cell phones and laptop computers, are powered by lithium-ion batteries. Until now, manufacturers have had to design their devices around the size and shape of commercially available batteries. But researchers have developed …
“Lithium-ion batteries commonly used in consumer electronics are notorious for bursting into flame when damaged or improperly packaged. These incidents occasionally have grave consequences, including burns, house fires and at least one plane crash. Inspired by the weird behavior of …
