In this work, we investigated the blood platelet adhesion and activation of truly superhemophobic surfaces and compared them with that of hemophobic surfaces and hemophilic surfaces. Our analysis indicates that only those superhemophobic surfaces with a robust Cassie-Baxter state display significantly lower platelet adhesion and activation. The understanding gained through this work will lead to the fabrication of improved hemocompatible, superhemophobic medical implants.

The present invention relates to hollow nanocoils having a three-dimensional helical structure in the form of a hollow tube and a method of manufacturing the same.

Carbon nanostructures are synthesized from a feedstock that includes polyethylene terephthalate. In a first furnace, the feedstock that includes polyethylene terephthalate and calcium oxide (CaO) or calcium hydroxide (Ca(OH).sub.2) are pyrolyzed to obtain one or more gaseous decomposition products. The gaseous decomposition productions are optionally filtered to remove any solid particles. The one or more gaseous decomposition products are passed across a stainless steel substrate in a second furnace to form the carbon nanostructures.

The present invention comprises the steps of contacting a boron nitride nanotube and a stabilizer in a solvent, and removing a portion of the solvent to obtain a liquid crystal composition including a liquid crystal in which at least a portion of the stabilizer is adsorbed on the surface of the boron nitride nanotube.

The present disclosure describes embodiments of novel methods and processes for forming CNT dispersions in media using a basket milling process. In particular, the methods and processes disperse CNT without damaging individual particles or affecting the properties of the particles. Testing of such methods demonstrates that recirculatory milling processes can be used to disperse SWNCT effectively and efficiently in a media.

A carbon allotrope element includes a carbon allotrope layer formed from a carbon allotrope material impregnated with a dielectric resin and having a first surface. The carbon allotrope element further includes a first bus bar in communication with the first surface, and a second bus bar in communication with the first surface and non-adjacent to the first bus bar. The first surface includes a layer of the dielectric resin and a plurality of abraded regions, and each of the first and second bus bars is in communication with one of the plurality of abraded regions of the first surface.

Disclosed herein are processes for purifying as-synthesized boron nitride nanotube (BNNT) material to remove impurities of boron, amorphous boron nitride (a-BN), hexagonal boron nitride (h-BN) nanocages, h-BN nanosheets, and carbon-containing compounds. The processes include heating the BNNT materials at different temperatures in the presence of inert gas and a hydrogen feedstock or in the presence of oxygen.

Boron nitride nanotubes (BNNTs) having a second scintillating material, and in some embodiments an enhanced 10B content, may be used for efficient thermal neutron detection. The second scintillating material may be a crystal coating on the nanotubes, and/or crystal dispersed within the BNNT material. Crystal-coated BNNT materials enable detecting thermal neutrons by detecting light from the decay products of the thermal neutron’s absorption on the 10B atoms in the BNNT material, as the resultant decay products pass through the crystal-coating. Embodiments of thermal neutron detectors are described. Methods for preparing BNNTs with a second scintillating material are also described.

Described herein are apparatus, systems, and methods for the continuous production of BNNT fibers, BNNT strands and BNNT initial yarns having few defects and good alignment. BNNTs may be formed by thermally exciting a boron feedstock in a chamber in the presence of pressurized nitrogen. BNNTs are encouraged to self-assemble into aligned BNNT fibers in a growth zone, and form BNNT strands and BNNT initial yarns, through various combinations of nitrogen gas flow direction and velocities, heat source distribution, temperature gradients, and chamber geometries.
