摘要： Various systems and methods relating to two-dimensional materials such as graphene. A membrane include a cross-linked graphene platelet polymer that includes a plurality of cross-linked graphene platelets. The cross-linked graphene platelets include a graphene portion and a cross-linking portion. The cross-linking portion contains a 4 to 10 atom link. The cross-linked graphene platelet polymer is produced by reaction of an epoxide functionalized graphene platelet and a (meth)acrylate or (meth)acrylamide functionalized cross-linker.

摘要： A method and system for detecting a target molecule. The method includes allowing a fluid containing the target molecule to pass by a complementary moiety attached to a paramagnetic ion so as to cause the complementary moiety and the paramagnetic ion to change a position. A magnetic effect change caused by the change in position of the paramagnetic ion is detected. The target molecule is identified based on the identity of the complementary moiety and the detected magnetic effect change.

摘要： A method for transferring a graphene sheet from a copper substrate to a functional substrate includes forming the graphene sheet on the copper substrate using chemical vapor deposition, and irradiating the graphene sheet disposed on the copper substrate with a plurality of xenon ions using broad beam irradiation to form a prepared graphene sheet. The prepared graphene sheet is resistant to forming unintentional defects induced during transfer of the prepared graphene sheet to the functional substrate. The method further includes removing the copper substrate from the prepared graphene sheet using an etchant bath, floating the prepared graphene sheet in a floating bath, submerging the functional substrate in the floating bath, and decreasing a fluid level of the floating bath to lower the prepared graphene sheet onto the functional substrate.

摘要： Two-dimensional materials can be formed into enclosures for various substances and a substrate layer can be provided on an outside and/or on an inside of the enclosure, wherein the enclosure is not cytotoxic. The enclosures can be exposed to an environment, such as a biological environment (in vivo or in vitro), where the fibrous layer can promote vascular ingrowth. One or more substances within the enclosure can be released into the environment, one or more selected substances from the environment can enter the enclosure, one or more selected substances from the environment can be prevented from entering the enclosure, one or more selected substances can be retained within the enclosure, or combinations thereof. The enclosure can, for example, allow a sense-response paradigm to be realized. The enclosure can, for example, provide immunoisolation for materials, such as living cells, retained therein.

摘要： It is often desirable to release graphene from its growth substrate. Present graphene release techniques can damage the graphene and produce significant quantities of hazardous waste. Electrowetting techniques can be used in alternative approaches for releasing graphene from its growth substrate. Methods for releasing graphene by electrowetting can include providing a metal substrate having graphene adhered thereto, applying a dielectric layer to the graphene to form a coated structure, placing the coated structure in a liquid medium, establishing an electrical potential between the metal substrate and a conductor disposed proximate to at least a portion of the dielectric layer such that the electrical potential induces infiltration of the liquid medium between at least a portion of the metal substrate and the graphene, and releasing the graphene from the metal substrate in the presence of the infiltrated liquid medium. The electrical potential can be maintained until the graphene is released.

摘要： Functional components of spacecraft structures can be subject to detrimental impacts by energetic particles produced from an electric propulsion system. A graphene coating applied to a functional component can maintain electrical conductivity upon a surface of the functional component, thereby allowing charge dissipation to take place, while also resisting sputtering erosion resulting from impacts of the energetic particles. Accordingly, spacecraft structures can include an electric propulsion system, a functional component that is at least partially impacted by an outflow of the electric propulsion system, and a graphene coating upon the functional component. Methods for operating such spacecraft structures can include generating an outflow of energetic particles from an electric propulsion system of a spacecraft structure, and at least partially impacting the outflow of energetic particles upon a functional component of the spacecraft structure, where the functional component has a graphene coating thereon.

摘要： Some embodiments comprise membranes comprising a first layer comprising a porous graphene-based material; a second layer comprising a porous graphene-based material; a channel positioned between the first layer and the second layer, wherein the channel has a tunable channel diameter; and at least one spacer substance positioned in the channel, wherein the spacer substance is responsive to the environmental stimulus. In some cases, the membranes have more than two layers of porous graphene-based material. Permeability of a membrane can be altered by exposing the membrane to an environmental stimulus. Membranes can be used in methods of water filtration, immune-isolation, timed drug release (e.g., sustained or delayed release), hemodialysis, or hemofiltration.

摘要： Production of perforated two-dimensional materials with holes of a desired size range, a narrow size distribution, and a high and uniform density remains a challenge, at least partially, due to physical and chemical inconsistencies from sheet-to-sheet of the two-dimensional material and surface contamination. This disclosure describes methods for monitoring and adjusting perforation or healing conditions in real-time to address inter- and intra-sheet variability. In situ or substantially simultaneous feedback on defect production or healing may be provided either locally or globally on a graphene or other two-dimensional sheet. The feedback data can be used to adjust perforation or healing parameters, such as the total dose or efficacy of the perforating radiation, to achieve the desired defect state.
