Researchers from TU Delft combine spintronics and nanophotonics in 2D material

Researchers from the Kavli Institute of Nanoscience at TU Delft, working with the Netherlands Organisation for Scientific Research’s AMOLF institute, have now found a way to convert the spin information into a predictable light signal at room temperature. The discovery brings the worlds of spintronics and nanophotonics closer together and might lead to the development of an energy-efficient way of processing data, in data centres, for example.

Silicon nanoblock arrays create vivid colors with subwavelength resolution

Until now, the metamaterials used to create tunable color from structural geometry have been based on metals. Although effective in achieving high resolutions, metallic materials suffer from inherent energy losses at visible wavelengths, which makes optimizing color purity challenging. By comparison, the resonance of silicon materials enables high reflectance and purity.

Piecework at the nano assembly line

Scientists at the Technical University of Munich (TUM) have developed a novel electric propulsion technology for nanorobots. It allows molecular machines to move a hundred thousand times faster than with the biochemical processes used to date. This makes nanobots fast enough to do assembly line work in molecular factories. The new research results will appear as the cover story on 19th January in the renowned scientific journal Science.

Billions could be saved in shipping, aquaculture

Nano surfaces inspired by carnivorous plants delay degradation. Sydney scientists have developed nanowrinkled coatings that could avoid the build-up of damaging biological material and save some of the $320 million annually spent by the Australian shipping industry because of biofouling.

Building Molecular Wires, One Atom at a Time

Electronic devices are getting smaller and smaller. Early computers filled entire rooms. Today you can hold one in the palm of your hand. Now the field of molecular electronics is taking miniaturization to the next level. Researchers are creating electronic components so tiny they can’t be seen with the naked eye.

Macrophage Nanosponges Could Keep Sepsis In Check

A team of researchers at the University of California San Diego has developed macrophage “nanosponges” that can safely absorb and remove molecules from the bloodstream that are known to trigger sepsis. These macrophage nanosponges, which are nanoparticles cloaked in the cell membranes of macrophages, have so far improved survival rates in mice with sepsis.
