摘要： An electrode includes a network of compressed interconnected nanostructured carbon particles such as carbon nanotubes. Some nanostructured carbon particles of the network are in electrical contact with adjacent nanostructured carbon particles. Electrodes may be used in various devices, such as capacitors, electric arc furnaces, batteries, etc. A method of producing an electrode includes confining a mass of nanostructured carbon particles and densifying the confined mass of nanostructured carbon particles to form a cohesive body with sufficient contacts between adjacent nanostructured carbon particles to provide an electrical path between at least two remote points of the cohesive body. The electrodes may be sintered to induce covalent bonding between the nanostructured carbon particles at contact points to further enhance the mechanical and electrical properties of the electrodes.

摘要： Polyhydroxyfullerenes (PHFs) having enhanced electron scavenging capabilities have a ratio of non-hydroxyl functional groups to hydroxyl functional groups that is less than or equal to 0.3. When combined with a semiconductor photocatalyst, such as titanium dioxide nanoparticles, the PHFs provide a photocatalyst for degradation of chemical and biological contaminates with an efficiency of at least twice that of titanium dioxide nanoparticles free of PHFs. The PHFs are included in these catalysts at a weight ratio to titanium dioxide of about 0.001 to about 0.003, whereas significantly lower and higher ratios do not achieve the highly improved photodegradation capability. PHFs outside of the desired structure are shown to be of little value for photodegradation, and can be inhibiting to the photocatalytic activity of TiO2. The enhanced electron scavenging PHFs can be employed as a component of materials for solar cells, field effect transistors, and radical scavengers.

摘要： Provided is conductive carbon which gives an electric storage device having a high energy density. This conductive carbon is characterized in having a hydrophilic solid phase component, where a crystallite size La that does not include a twist in a graphene surface direction and a crystallite size Leq that includes a twist in a graphene surface direction, which are calculated from a Raman spectrum of the hydrophilic solid phase component, satisfy the following relationships: 1.3 nm≦La≦1.5 nm, and 1.5 nm≦Leq≦2.3 nm, and 1.0≦Leq/La≦1.55. When performing a rolling treatment on an active layer including an active particle and this conductive carbon formed on a current collector during manufacture of an electrode of an electric storage device, the pressure resulting from the rolling treatment causes this conductive carbon to spread in a paste-like form and increase in density while covering the surface of the active particles, the conductive carbon being pressed into gaps formed between adjacent active particles and filling the gaps. As a result, the amount of active material per unit volume in the electrode obtained after the rolling treatment increases, and the electrode density increases.

摘要： A method for making a variable-density carbon nanotube film is provided. A drawn carbon nanotube film, including a number of carbon nanotubes aligned along an aligned direction, is prepared. A number of thin regions are formed in the drawn carbon nanotube film along the aligned direction by reducing density of carbon nanotubes in each of the plurality of thin regions. A variable-density carbon nanotube film is provided and includes a number of thin regions and at least one normal region having a density of carbon nanotubes greater than that of the thin regions. The at least one normal region includes a number of carbon nanotubes substantially aligned along an aligned direction.

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.
