摘要： Flexible and stretchable electronics, including supercapacitors and pressure sensors, are made using carbon nanostructures produced by providing a first composite structure which includes a temporary substrate and an array of carbon nanotubes arranged in a stack on a surface of the temporary substrate such that the stack of carbon nanotubes is oriented generally perpendicular to the surface of the temporary substrate, which may include silicon dioxide. The stack of carbon nanotubes is transferred from the temporary substrate to another substrate, which includes a curable polymer, thereby forming another composite structure comprising the stack of carbon nanotubes and the cured polymer.

摘要： A method of high-throughput printing and selective transfer of graphene onto a substrate includes the steps of: providing a thermal release tape having graphene adhered thereto; placing a substrate onto the graphene; pressing the thermal tape and the graphene against the substrate at a uniformly-distributed pressure; heating localized portions of the thermal tape and graphene using a localized heat source, thereby diminishing the adhesive properties of the thermal release tape in the localized portions and transferring graphene from said localized portions to the substrate; and separating the thermal release tape from the substrate. The method may include the further step of moving the localized heat source to selected positions on the thermal release tape during the heating step, thereby forming a pattern of heated portions. The method may use a laser beam as the localized heat source, movement of the laser beam being performed by a computer-controlled deflectable mirror.

摘要： Smart membranes (14) are integrated into a small, unmanned surface vessel (20) to enable the efficient, automated cleanup of oil spills. Such a vessel (20) has the potential to provide a low-cost, modular solution for day-to-day oil-spill cleanup operations, especially in confined aquatic areas, such as under piers and in the small spaces between marine vessels and piers. The smart membranes (14) are provided on the surface of a conveyor belt (34) that circulates the membranes (14) through the surrounding body of water (10) for oil collection, as well as through an internal reduction chamber (22) of the vessel (20) for oil release. The smart membranes (14) are adapted to attract and repel oil (12) in response to low-voltage commands applied across the conveyor belt (34), using a process that is repeatable for a number of cycles, offering high efficiency and long durability (FIG. 5).

摘要： The exemplary embodiments describe techniques for a controlled chemical vapor deposition growth and transfer of arrayed TMD monolayers on predetermined locations, which enable the formation of single crystalline TMD monolayer arrays on specific locations. The unique growth process includes the patterning of transition metal oxide (e.g., MoO3) on the source substrate contacting the growth substrate face-to-face, where the growth of single crystalline TMD monolayers with controlled size and location, exclusively on predetermined locations on the growth substrates is accomplished. These TMD arrays can be align-transferred using a unique process that combines the wet and stamping transfer processes onto any target substrate with a pin-point accuracy, which dramatically enhances the integrity of transferred TMDs.
