Researchers have developed a low-cost technique that holds promise for a range of scientific and technological applications. They have combined laser printing and capillary force to build complex, self-assembling microstructures using a technique called laser printing capillary-assisted self-assembly (LPCS).
An almost 4% absolute increase to the previous record is achieved by applying a thin passivating film on the nanostructures by Atomic Layer Deposition, and by integrating all metal contacts on the back side of the cell.
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.
