摘要:
A method for manufacturing indium tin oxide nanowires by preparing a solution that includes an indium-containing species, a tin-containing species and a polymeric material, wherein the solution has a molar ratio of tin to indium in a range from about 5 to about 15 percent, electrospinning fibers using the solution, and heating the fibers to a calcination temperature and maintaining the fibers at the calcination temperature for a predetermined calcination time.
摘要:
A method of preparing a transparent conductor for application on a polymeric substrate is described. The method includes introducing a functional group onto a surface of the conductor to form a modified conductor, and mixing the modified conductor with a dispersant at slightly elevated temperatures to form a conductive material composition. The dispersant is at least bifunctional. The conductive material composition may then be applied to the polymeric substrate. The dispersant acts as a linker, bonding the transparent conductor and polymeric substrate such that they are fully integrated.

摘要:
The present invention provides methods for fabricating a fuel cell membrane structure that can dramatically reduce fuel crossover, thereby improving fuel cell efficiency and power output. Preferred composite membrane structures include an inorganic layer situated between the anode layer and the proton-exchange membrane. The inorganic layer can conduct protons in unhydrated form, rather than as hydronium ions, which reduces fuel crossover. Some methods of this invention include certain coating steps to effectively deposit an inorganic layer on an organic proton-exchange membrane.
摘要:
A monomeric formulation for creating self-propagating polymer optical waveguides and a system and a method of using the same. The monomeric formulation includes a plurality of unsaturated molecules, a molecule having a structure of R—X—H (e.g., X═O, S, N), and a photoinitiator. The monomeric formulation can further include a free radical inhibitor. The system includes a light source, a reservoir having a monomeric formulation and a patterning apparatus configured to guide a light beam from the light source into the monomeric formulation to form at least one self-propagating polymer waveguide.

摘要:
A combination of a substrate selected from silicon, silicon carbide or a metal and a graphene precursor having the following properties: (a) an aromatic structure that forms the basis of the graphene structure, said aromatic structure being selected from the group consisting of: benzene, naphthalene, pyrene, anthracene, chrysene, coronene, and phenanthrene, or a cyclic or acyclic structures which can be converted to aromatic structures and (b) functional groups that can react with each other to form additional aromatic structures.
摘要:
A three-dimensional biological scaffold. The scaffold includes at least three sets of polymer waveguides extending along at least three respective directions. The at least three sets of polymer waveguides interpenetrate each other at a plurality of nodes to form a self-supporting structure. In some embodiments, the polymer waveguides may be bio-degradable. In still some embodiments, the three-dimensional biological scaffold may include one or more coating layers for covering surfaces of the polymer waveguides.
摘要:
A method of coating a surface of a fuel cell plate is disclosed herein. The method involves forming a sol gel mixture including a metal oxide modified with at least one functional group, where the at least one functional group is configured to improve adhesion; and adding carbon modified with a hydrophilic functional group to the mixture, thereby forming a suspension. The suspension is applied to the surface of the fuel cell plate, and is activated to form a porous, hydrophilic, and conductive film on the surface of the fuel cell plate.
