Embodiments of techniques and systems for parallel XML parsing are described. An event-level XML parser may include a lightweight events partitioning stage, parallel events parsing stages, and a post-processing stage. The events partition may pick out event boundaries using single-instruction, multiple-data instructions to find occurrences of the “

摘要:
A method of forming carbon nanotube-polymer composites includes the steps of forming a mixture solution including a plurality of carbon nanotubes dispersed in a co-solvent. The co-solvent includes an organic solvent and a second solvent being a short chain fluorinated carboxylic acid having a boiling point below 150° C. which is less oxidizing than nitric acid, and is soluble in both the organic solvent and water. The first polymer is mixed with the mixture solution to form a polymer including mixture. The co-solvent is removed from the polymer mixture to form a dispersed nanotube-polymer composite. The second solvent can be trifluoroacetic acid.

A superhydrophobic coating can have a water contact angle greater than 150°. The coating can remain superhydrophobic after being immersed in water for one week.
摘要:
A composition of matter includes at least one carbon nanotube (CNT) or a graphene type structure having an outer surface, and a plurality of crystalline polymer supramolecular structures that include a conjugated polymer that are non-covalently secured to the outer surface of the CNTs or the graphene type structure. The conjugated polymer can be a conjugated homopolymer or a block copolymer including at least one conjugated block. The supramolecular structures extend outward from the outer surface of the CNTs or graphene type structures.
摘要:
An aerogel includes a plurality of supramolecular structures bound to one another. Each supramolecular structure includes a carbon nanotube (CNT) or graphene type structure having an outer surface, and a plurality of polymers or aromatic molecules secured to the outer surface of the CNT or graphene type structure. The plurality of polymers or aromatic molecules have at least one crosslinkable structure. The supramolecular structures are crosslinked together by chemical bonding between the crosslinkable structures. The polymers can be block copolymers including at least one conjugated polymer block and at least one block of a crosslinkable non-conjugated polymer that provides the cross linkable structure, where the conjugated polymer block is non-covalently bonded to the outer surface of the CNT or graphene type structure.

A surface with superhydrophobic and hydrophilic or superhydrophilic regions can be made. The hydrophilic or superhydrophilic regions can selective collect water on the surface.
摘要:
A carbon nanotube-polymer composite includes a polymer continuous phase having at least a first polymer, and a plurality of carbon nanotubes dispersed in the polymer continuous phase. The carbon nanotubes are non-functionalized nanotubes. The carbon nanotubes are between 0.05 and 40 weight % of the composite. At least 98% of the carbon nanotubes are not involved in nanotube bundles.
