摘要： The invention discloses a simple, scalable and convenient solvothermal method of obtaining fluoralkylated carbon quantum dots—Fluocar® Nano materials, by solvothermal pyrolysis of an organic substance in the presence of fluoroorganic substance that contain fluoroalkyl groups. The obtained material is water- and organic solvents soluble, grafted fluorine is hydrolytically stable, and obtained dots having intense luminescence in a wide range of wavelengths, from blue to NIR. Photoluminescent (PL) spectral map of obtained carbon dots solution is highly sensitive to pH changes and rare earth metal ions concentration in this solution. Also PL-map of such material is sensitive to organic complex moiety (e.g. Acidum salicylicum, and penicillinum).
Synthesized materials can find use as the classic and fluorescent dye replacement, as the carrier of biologically active substances, for bio-imaging, theranostic, for cytological studies, (photo)catalysis, as electrode component, as well as a sensor or biosensor, or for other uses.

摘要： Particulate material comprising rough mesoporous hollow nanoparticles. The rough mesoporous hollow nanoparticles may comprise a mesoporous shell, the external surface of which has projections thereon, the projections having smaller sizes than the particle size. The particulate material may be used to deliver active agents, such as insecticides and pesticides. The active agents can enter into the hollow core of the particles and be protected from degradation by sunlight. The rough surface of the particles retains the particles on plant leaves or animal hair. Methods for forming the particles are also described. Carbon particles and methods for forming carbon particles are also described.

摘要： There is provided a method for producing a carbon material, including a carbon generation step of causing carbon dioxide to react with a reducing agent to generate carbon, in which, as the reducing agent, an oxygen-deficient iron oxide represented by Fe3O4-δ (where δ is 1 or more and less than 4), which is obtained by reducing magnetite while maintaining a crystal structure, or an oxygen-completely deficient iron (δ=4) which is obtained by completely reducing magnetite is used.

摘要： Oxygen-containing graphenic nanomaterial (OGN)-doped novolac polymers suitable for producing graphitized carbon may be synthesized based on a correlation between (a) the amount of OGN and/or the oxygen content of the OGN and (b) at least one property of a resultant graphitized carbon. For example, a method may comprise: synthesizing an OGN-doped novolac polymer, wherein an amount of OGN and/or an oxygen content of the OGN used in the synthesizing is based on a correlation between (a) the amount of OGN and/or the oxygen content of the OGN and (b) at least one property of a resultant graphitized carbon; and carbonizing and graphitizing the OGN-doped novolac polymer to yield a graphitized carbon.

摘要： Methods of producing functionalized carbon nanosheets capable of use as electrode materials in electrochemical energy storage cells, electrodes and electrode materials formed thereby, and electrochemical energy storage cells of sodium-ion batteries that utilize such electrodes and electrode materials. Such a method of producing functionalized carbon nanosheets includes preparing a solution containing dissolved glucose, mixing a quantity of NaCl crystals with the solution to form a mixture, drying the mixture to form a gel comprising NaCl crystals each having a layer of glucose thereon, heating the gel in an inert atmosphere to a processing temperature and for a duration sufficient to cause carbonization of the glucose and in situ functionalization with oxygen-containing functional groups, and removing the NaCl crystals to yield the functionalized carbon nanosheets.

A polymer template is provided, the polymer template includes a polymer compound, and the polymer template has a plurality of pores. A coating step is performed, wherein a metal compound is coated on the polymer template to form a transition intermediate. A heating step is performed, wherein the transition intermediate is heated to transform the polymer template to a carbon template and transform the metal compound to a coating layer, and a porous carbon composite material is formed. A removing step is performed, wherein the coating layer is removed from the porous carbon composite material, and a porous carbon material is obtained.

摘要： A system and process for producing doped carbon nanomaterials is disclosed. A carbonate electrolyte including a doping component is provided during the electrolysis between an anode and a cathode immersed in carbonate electrolyte contained in a cell. The carbonate electrolyte is heated to a molten state. An electrical current is applied to the anode, and cathode, to the molten carbonate electrolyte disposed between the anode and cathode. A morphology element maximizes carbon nanotubes, versus graphene versus carbon nano-onion versus hollow carbon nano-sphere nanomaterial product. The resulting carbon nanomaterial growth is collected from the cathode of the cell.

摘要： Nanoporous carbon-based scaffolds or structures, and specifically carbon aerogels and their manufacture and use thereof. Embodiments include a cathode material within a lithium-air battery, where the cathode is formed of a binder-free, monolithic, polyimide-derived carbon aerogel. The carbon aerogel includes pores that improve the oxygen transport properties of electrolyte solution and improve the formation of lithium peroxide along the surface and/or within the pores of the carbon aerogel. The cathode and underlying carbon aerogel provide optimal properties for use within the lithium-air battery.
