Sometimes, seeing clearly requires complete black. For astronomy and precision optics, coating devices in black paint can cut down on stray light, enhancing images and boosting performance. For the most advanced telescopes ...
It might look like a roll of chicken wire, but this tiny cylinder of carbon atoms—too small to see with the naked eye—could one day be used for making electronic devices ranging from night vision goggles and motion detectors ...
Carbon nanotubes have shown promise for everything from microelectronics to aviation to energy storage. Researchers think this material might one day fulfill the science fiction dream of creating an elevator to space.
Current lithium-ion battery technology does not have the energy density necessary to meet the demands for renewable energy. In theory, lithium-sulfur batteries could be a viable alternative with a higher specific capacity ...
Polychlorinated dibenzo-p-dioxins and dibenzofurans are dangerous pollutants due to their carcinogenicity and persistence in the environment. Traditional catalytic oxidation methods for their removal face challenges like ...
Membranes of vertically aligned carbon nanotubes (VaCNT) can be used to clean or desalinate water at high flow rate and low pressure. Recently, researchers of Karlsruhe Institute of Technology (KIT) and partners carried out ...
Electrocatalysis plays a vital role in developing clean energy, greenhouse gas removal and energy storage technologies. A study co-led by City University of Hong Kong (CityU) researchers found that single-walled carbon nanotubes ...
Humanity's quest to explore—and, perhaps eventually, colonize—outer space has prompted a great many ideas about how precisely to go about it.
Oxidation can degrade the properties and functionality of metals. However, a research team co-led by scientists from City University of Hong Kong (CityU) recently discovered that severely oxidized metallic glass nanotubes ...
The past few decades have seen astonishing advances in imaging technology, from high-speed optical sensors that process over two million frames per second to tiny lensless cameras that record images using a single pixel.
