HYPEREUTECTIC SILUMIN.NANOSTRUCTURAL PROCESSES OF MELTING AND MOULDING

Литьë и металлургия, 2017
It is shown that melting and molding of hypereutectic silumin are complicated physical and chemical nanostructural processes. The major part at these processes is played by the centers of crystallization of primary crystals of silicon, silicon ...

Ion beam processing of DNA origami nanostructures

Beilstein Journal of Nanotechnology
DNA origami nanostructures are emerging as a bottom-up nanopatterning approach. Direct combination of this approach with top-down nanotechnology, such as ion beams, has not been considered because of the soft nature of the DNA material. Here we demonstrate that the shape of 2D DNA origami nanostructures deposited on Si substrates is well preserved upon

LASER SYNTHESIS AND PROCESSING OF COMPOSITE NANOSTRUCTURES

Journal of Chemical Technology and Metallurgy
The present work reports the fabrication of porous composite ZnO/noble metal (Ag, Au) nanostructures using ps-pulsed laser deposition at atmospheric pressure. The PLD grown samples are ns-laser annealed, which led to a surface modification and formation of nanoparticles and NP’s aggregates.
