Engineers have shown how liquid crystals can be employed to create compound lenses similar to those found in nature. Taking advantage of the geometry in which these liquid crystals like to arrange themselves, the researchers are able to grow compound lenses with controllable sizes.
Scientists have developed a method using infrared spectroscopy and atomistic modeling that would allow to better understand the mechanism behind the extreme ion selectivity and transport properties in ion channels.
Scientists have been able to switch ferromagnetic domains on and off with low voltage in a structure made of two different ferroic materials. The switching works slightly above room temperature. Their results might inspire future applications in low-power spintronics, for instance for fast and efficient data storage.
Nanoengineers developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by MRSA (methicillin-resistant Staphylococcus aureus), an antibiotic-resistant bacteria. This nanosponge-hydrogel minimized the growth of skin lesions on mice infected with MRSA - without the use of antibiotics.
A team of leading computer scientists, roboticists and biologists have come together to develop a system that combines the capabilities of nanoscale robots with specially designed synthetic organisms. Together, they believe this hybrid 'bio-CPS' will be capable of performing heretofore impossible functions, from microscopic assembly to cell sensing within the body.
Researchers have identified for the first time that a performance gain in the electrical conductivity of random metal nanowire networks can be achieved by slightly restricting nanowire orientation. The most surprising result of the study is that heavily ordered configurations do not outperform configurations with some degree of randomness; randomness in the case of metal nanowire orientations acts to increase conductivity.
Rersearchers used used high-intensity X-rays to investigate color-producing nanostructures within hair-like structures that cover some species of butterflies, weevils and beetles, bees, and spiders and tarantulas. They found that the architecture of these nanostructures are identical to chemical polymers engineered by chemists and materials scientists.
Made from state-of-the-art silicon transistors, an ultra-low power sensor enables real-time scanning of the contents of liquids such as perspiration. Compatible with advanced electronics, this technology boasts exceptional accuracy - enough to manufacture mobile sensors that monitor health.
