Nanowerk February 28, 2018 Researchers in Russia used magnet-driven nanoparticles consisting of two key components – thrombin, an enzyme responsible for blood clotting and magnetite. Thrombin interacts with the protein called fibrinogen and triggers clot formation to block the damaged vessel. The thrombin is wrapped into a special porous matrix made of magnetite that allows for precise control of the movement of particles inside the body using an external magnetic field. A drug based on these nanoparticles is nontoxic and can be injected intravenously and delivered straight to the site of a vascular injury. It can accelerate local clot formation […]

Scientists create high-speed coding system
Physorg January 23, 2018 Researchers in Russia have proposed and demonstrated a scheme for optical encoding of information based on the formation of wave fronts that works with spatially incoherent illumination. They used a liquid-crystal phase light modulator as the encoding element, where pre-synthesized diffraction optical elements are displayed. The camera’s image sensor detects the optical convolution of the image that is produced by the amplitude modulator with the pulse response of the diffractive element, derived on the phase modulator. They successfully encoded and decoded the images of QR codes with a size up to 129×129 elements. The percentage of […]
