Abstract:
Functionalized membranes for use in applications, such as electrodeionization, can be prepared simply and efficiently by contacting a conductive carbon nanotube and polymer membrane with a solution containing at least one electrochemically active and functional compound under conditions suitable for electrochemically depositing the electrochemically active and function compound on a surface of the membrane.
Abstract:
Examples of touch screen interfaces with pulse oximetry are generally described, along with examples of methods of determining pulse rate, blood oxygen level, or both, with a touch screen interface.
Abstract:
The present disclosure generally relates to methods and systems for forming phase change material composites and to the thus formed phase change material composites. In some examples, a method for forming a phase change material (PCM) composite may include dispersing nanowire material in a nonpolar solvent to form a nanowire-solvent dispersion, adding a PCM to the nanowire-solvent dispersion to form a nanowire-solvent-PCM dispersion, heating the nanowire-solvent-PCM dispersion, and removing the solvent.
Abstract:
Fluorophores or other indicators can be used to label and identify one or more defects in a graphene layer by localizing at the one or more defects and not at other areas of the graphene layer. A substrate having a surface at least partially covered by the graphene layer may be contacted with the fluorophore such that the fluorophore selectively binds with one or more areas of the surface of the underlying substrate exposed by the one or more defects. The one or more defects can be identified by exposing the substrate to radiation. A detected fluorescence response of the fluorophore to the radiation identifies the one or more defects.
Abstract:
A flame retardant additive includes red phosphorus adsorbed into a porous carrier. The carrier may be mixed with white phosphorus above its melting point (41° C.), so that liquid phosphorus is pulled into the pores of the carrier by capillary action. The phosphorus-loaded carrier may be heated above 250° C. to convert the white phosphorus to red phosphorus. The resulting red phosphorus-loaded carrier may retain flame retardant activity, and may also be protected from the environment for easier handling and formulation. By employing a carrier of a suitably small particle size, it is practical to incorporate the flame retardant red phosphorus-loaded carrier in thin films.
Abstract:
Technologies described herein are generally related to systems and processes for repairing a graphene membrane on a support. A chamber may receive a layer of graphene on a support. The layer of graphene may include a hole. A first container including an initiator may be effective to apply an initiator through the hole to the support to functionalize the support and produce an initiator layer on the support. A second container including an activator may be effective to apply an activator through the hole to the initiator layer to activate the initiator layer. The application of the activator may further be effective to grow a polymer from the initiator layer. The growth of the polymer may be effective to produce a polymer plug in the hole and effective to repair at least a portion of the layer of graphene.
Abstract:
Windows, or other types of transparent materials, may be constructed to passively allow light from alternate sources to pass therethrough, while also being able to actively produce artificial light for providing illumination from one side of the window by means of an incorporated optical waveguide that accepts light from an edge of the window and disperses it from only one side of the window.
Abstract:
Technologies are generally described for methods, systems, and structures that include patterns formed by optical lithography. In some example methods, a photoresist layer is applied to a substrate, and a graphene layer can be applied to the photoresist layer. Light can be applied through a mask to the graphene layer, where the mask includes a pattern. The light can form the pattern on the graphene layer such that the pattern forms on the photoresist layer.
Abstract:
Microparticles that encapsulate a fire extinguishing agent or combination of fire extinguishing agents, methods for preparing these microcapsules, methods for using such microcapsules, and articles of manufacture including at least one of such microparticles either in a coating or in a matrix that makes up a structural component of the article of manufacture are disclosed.
