Abstract: The present invention provides a method for preparation of sulfur functionalized graphene which contains the following steps: a) providing a dispersion of fluorinated graphite; b) subjecting the dispersion of fluorinated graphite to sonication and/or mechanical treatment and/or thermal treatment; c) preparing a metal polysulfide, starting from a metal sulfide and sulfur; d) contacting the product from step b) with the product of step c) at a temperature within the range of 10-110° C.; e) separating the solid product formed in step d) from the solution. Further provided are sulfur functionalized graphene with high sulfur loading obtained by this method, and its use in electrical cells.

Abstract: A particulate form of dithiocarbamate-metal complex and at least one blood protein. The particulate form is obtained by a process having a sequential or simultaneous addition of individual components, resulting in their self-assembling. The aqueous dispersion of the particulate form is suitable for parenteral, oral and topical administration and for therapy and visualization of cancer.

Abstract: A thermoplasmonic device includes a titanium film and a plurality of titanium nitride tube elements disposed on the titanium film. Each of the titanium nitride tube elements includes an open top and a titanium nitride bottom. Each of the titanium nitride tube elements has titanium nitride tubular middle portion that extends from the open top to the titanium nitride bottom.

Abstract: Titanium nitride (TiN) nanofurnaces are fabricated in a method that involves anodization of a titanium (Ti) foil to form TiO2 nanocavities. After anodization, the TiO2 nanocavities are converted to TiN at 600° C. under ammonia flow. The resulting structure is an array of refractory (high-temperature stable) subwavelength TiN cylindrical cavities that operate as plasmonic nanofurnaces capable of reaching temperatures above 600° C. under moderate concentrated solar irradiation. The nanofurnaces show near-unity solar absorption in the visible and near infrared spectral ranges and a maximum thermoplasmonic solar-to-heat conversion efficiency of 68 percent.

Abstract: The two-step immobilisation of silver nanoparticles on solid substrates using polyethylenimine as adhesive and reduction linker, where the primary coating of solid substrates by polyethylenimine occurs followed by production of silver nanoparticles covalently anchored on polymer surface thanks to reduction effect of its functional groups and therefore, no nanoparticles are released to environment. The method permits working under aqueous conditions, does not use any reducing agents, stabilisers or toxic solvents and can universally be applied for anti-microbial treatments of all types of solid substrates.
