Abstract: Composite materials with few or no void defects are described. The composites can include nanoporous network materials. Methods and systems for the fabrication of the composite materials are generally described. According to certain embodiments, composite materials are fabricated without the use of an autoclave or low pressure environments.

Abstract: A method and an apparatus for welding a first object to a second object, wherein the first object is produced from a thermoset and comprises a thermoplastic material outer layer, wherein the second object comprises at least one thermoplastic material outer layer. In addition, a layer of carbon nanotubes is applied to the thermoplastic material outer layer of the first object, and the second object is placed onto the first object. At least some of the thermoplastic material outer layer of the second object lies atop the applied layer of carbon nanotubes. In addition, a potential is applied to the layer of carbon nanotubes, such that an electrical current flows through the carbon nanotubes, wherein the thermoplastic material outer layer of the first object and the thermoplastic material outer layer of the second object are heated and are welded to one another.

Abstract: The devices and systems described herein include one or more fluid paths, e.g., channels, and one or more selectively permeable obstacles arranged in the fluid path(s), each including a plurality of aligned nanostructures, e.g., nanotubes or nanorods, defining an outer surface of the obstacle and an internal network of voids. The obstacle(s) can further include binding moieties applied to the outer surface and/or to the surfaces of the individual nanostructures within the obstacle(s). The devices can be manufactured by forming the dense groupings of nanostructures to extend outwards and upwards from a substrate; forming a fluidic channel, bonding the fluidic channel to the substrate; and optionally applying binding moieties to the obstacles. The devices can be used to manipulate cells within fluid samples.

Abstract: The present invention provides methods for uniform growth of nanostructures such as nanotubes (e.g., carbon nanotubes) on the surface of a substrate, wherein the long axes of the nanostructures may be substantially aligned. The nanostructures may be further processed for use in various applications, such as composite materials. For example, a set of aligned nanostructures may be formed and transferred, either in bulk or to another surface, to another material to enhance the properties of the material. In some cases, the nanostructures may enhance the mechanical properties of a material, for example, providing mechanical reinforcement at an interface between two materials or plies. In some cases, the nanostructures may enhance thermal and/or electronic properties of a material. The present invention also provides systems and methods for growth of nanostructures, including batch processes and continuous processes.
