    Abstract: Systems, devices, and methods for printing on surfaces of three-dimensional objects are provided. The systems, devices, and methods allow for images, and three-dimensional structures, to be printed onto a surface of a three-dimensional object. The surface of the three-dimensional object can have many different shapes, including an arbitrary or non-uniform shape having multiple curves. In one exemplary embodiment, the method includes associating a pattern of polygons with a surface of a three-dimensional object and then scaling a pattern of polygons associated with an image to be printed onto the surface with the pattern of polygons associated with the surface. One or more polygons of the scaled pattern of polygons are then progressively projected onto the surface, and a photosensitive material associated with the surface is cured to set projected image portion on the surface. Systems, devices, and other methods for printing onto surfaces of three-dimensional objects are also provided.

    Abstract: The present disclosure is directed to the creation and/or manipulation of microfluidic systems and methods that can be formed in pre-existing modular blocks. Microfluidic paths can be formed in one or more blocks, and when multiple blocks are used, the blocks can be used together to form a path across the blocks. The paths can be sealed to prevent fluid leakage. The modular blocks can be readily available blocks which can then be individually customized to achieve various microfluidic design goals. The paths can be formed in outer surfaces of the blocks and/or disposed through a volume of the blocks. The modular blocks can have a uniform design across various block types, making it easy to reconfigure systems and/or remove and replace blocks and other components of the system. Methods for constructing such systems, and using such systems, are also provided.

    Abstract: Nanoliter pipette assembly. The assembly includes a housing containing a working fluid in a working fluid chamber therein and includes a moveable piston within the housing, the piston moveable by a linear actuation mechanism for contact with the working fluid. A tip portion is provided that includes a diaphragm deformable to engage an inner portion of the tip. It is preferred that the diaphragm have a projecting three-dimensional structure for direct contact with a liquid.

    Abstract: A nanoporous stamp for printing a variety of materials is disclosed. The nanoporous stamp may include a substrate and an array of carbon nanotubes disposed on and attached to the substrate. The array of carbon nanotubes can have an etched top surface and a wettable, nanoporous structure, and may include a coating thereon. The nanoporous stamp can be used in a variety of printing applications, and can print, among other things, colloidal and non-colloidal inks on a variety of substrates with a high degree of accuracy and fidelity.

    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.
