Energy-storage devices in which the energy storage device has an electrode that includes graphitic carbon, carbon nanotubes, and a metallic-lithium layer between the carbon nanotubes and the energy-storage device further has an electrolyte that is in contact with the metallic lithium layer. The methods of manufacturing the energy-storage devices include that the energy storage device is made by providing electrodes that have a layer of carbon nanotubes adjacent additional carbon, applying a layer of lithium between the carbon nanotubes in the layer of carbon nanotubes of at least one of the electrodes, and providing an electrolyte between the electrodes.

Energy-storage devices having electrodes containing carbon nanotubes and methods of making same

Systems and methods that utilize a separator coated by particles for Li dendrite detection in an ordinary two-electrode battery system. The particles can be red phosphorus (RP) particles and/or other particles that are poor electronic conductors, are able to react with Li, and will form an insoluble product with Li, such as silicon, germanium, arsenic, metal oxides, metal halides, metal chalcogenides, chalcogenides, and LiMEO(M=metal, E=nonmetal, O=oxygen, x≥0, y≥0, z≥0). These other particles can be used by themselves or in combination with one another. No additional electrode is needed, and the presence of Li dendrites can be detected simply based on the voltage profile during the charging step.

Systems and methods of detecting Li dendrites

Modified hydrophilic carbon clusters (HCCs), poly(ethylene glycol)-hydrophilic carbon clusters (PEG-HCCs) and similarly structured materials like graphene quantum dots (GQDs), PEGylated GQDs, small molecule antioxidants, and PEGylated small molecule antioxidants. These materials have been modified with an iron chelating moiety, deferoxamine, or a similar chelating moiety. By exploiting common binding sites, the carbon nanostructure facilitates intracellular transport including in mitochondria, reduces oxidative breakdown of the chelator moiety prior to treatment, and reduces both the cause and consequences of metal induced oxidative stress within the body thus providing a novel form of therapy for a range of oxidative and metal-related toxicities. Graphenic materials can be used for the treatment of acute and chronic mitochondrial electron transport chain dysfunction.

Anodes, cathodes, and separators for batteries (electrochemical energy storage devices). The anodes are Li metal anodes having lithiated carbon films (Li-MWCNT) (as dendrite suppressors and protective coatings for the Li metal anodes). The cathodes are sulfurized carbon cathodes. The separators are GNR-coated (or modified) separators. The invention includes each of these separately (as well as in combination both with each other and with other anodes, cathodes, and separators) and the methods of making each of these separately (and in combination). The invention further includes a battery that uses at least one of (a) the anode having a lithiated carbon film, (b) the sulfurized carbon cathode, and (c) the GNR-modified separator in the anode/cathode/separator arrangement. For instance, a full battery can include the sulfurized carbon cathode in combination with the Li-MWCNT anode or a full battery can include the sulfurized carbon cathode in combination with other anodes (such as a GCNT-Li anode).

Methods that expand the properties of laser-induced graphene (LIG) and the resulting LIG having the expanded properties. Methods of fabricating laser-induced graphene from materials, which range from natural, renewable precursors (such as cloth or paper) to high performance polymers (like Kevlar). With multiple lasing, however, highly conductive PEI-based LIG could be obtained using both multiple pass and defocus methods. The resulting laser-induced graphene can be used, inter alia, in electronic devices, as antifouling surfaces, in water treatment technology, in membranes, and in electronics on paper and food Such methods include fabrication of LIG in controlled atmospheres, such that, for example, superhydrophobic and superhydrophilic LIG surfaces can be obtained. Such methods further include fabricating laser-induced graphene by multiple lasing of carbon precursors. Such methods further include direct 3D printing of graphene materials from carbon precurors. Application of such LIG include oil/water separation, liquid or gas separations using polymer membranes, anti-icing, microsupercapacitors, supercapacitors, water splitting catalysts, sensors, and flexible electronics.

An electrochemical cell with a lithium-metal anode that suppresses dendrite formation and can be fabricated using a simple, inexpensive, and solvent-free process. The anode is coated with a layer of disordered nanomaterial, saturated with lithium ions, that suppresses dendrite formation during charging. The dendrite-suppression coating can be applied simply using a dry, abrasive technique in which the lithium-metal anode is alternately abraded to roughen the surface and polished using a polishing powder of a material that alloys with the lithium.

Three-dimensional (3D) printing of graphene materials and methods and apparatuses for making same. In some embodiments, combined metal powder and carbon growth sources (such as powder Ni and sucrose) are utilized in the 3D printing process. In other embodiments, metal powders with binders (such as powder Ni and a polymer bases binder) are utilized in the 3D printing process. The metal in the resulting 3D printed composite material can then be etched or otherwise removed yielding the 3D printed graphene materials.

Virus and microbe-killing, self-sterilizing resistive heated air filters and methods of making and using same methods. The air filter is includes laser-induced graphene (LIG), a porous conductive graphene foam formed through photothermal conversion of a polyimide film (or another source or source of polymer or other LIG precursor material) by a laser source. The LIG in the air filter can capture particulates and bacteria. The bacteria cannot proliferate even when submerged in culture medium. Through a periodic Joule-heating mechanism, the filter easily reaches greater than 300° C. This destroys any microorganisms including bacteria, along with molecules that can cause adverse biological reactions and diseases such as viruses, pyrogens, allergens, exotoxins, endotoxins, teichoic acids, mycotoxins, nucleic acids, and prions.

Embodiments of the present disclosure pertain to methods of opening a lipid bilayer by associating the lipid bilayer with a molecule that includes a moving component capable of moving (e.g., rotating) in response to an external stimulus; and exposing the molecule to an external stimulus before, during or after associating the molecule with the lipid bilayer. The exposing causes the moving component of the molecule to move and thereby open the lipid bilayer (e.g., by pore formation). The external stimuli may include an energy source, such as ultraviolet light. The opened lipid bilayer may be a component of cell membranes in vitro or in vivo. The opening of the lipid bilayer may allow for the passage of various materials (e.g., active agents, such as peptide-based drugs) through the lipid bilayer and into cells. Additional embodiments of the present disclosure pertain to the aforementioned molecules for opening lipid bilayers.
