Abstract:
A pixel electrode is provided, comprising a nanostructure-film deposited over an active matrix substrate, such that the pixel electrode makes electrical contact with an underlying layer. Similarly, auxiliary data pads and auxiliary gate pads are provided, which also comprise nanostructure-films deposited over an active matrix substrate, such that they make electrical contact with underlying layers.
Abstract:
Disclosed are single atom dispersions and multi-atom dispersions, and systems and methods for synthesizing the atomic dispersions. An exemplary method of synthesizing atomic dispersions includes: positioning a loaded substrate which includes a substrate which is loaded with at least one of: a precursor of an element or a cluster of an element, applying one or more temperature pulses to the loaded substrate where a pulse of the temperature pulse(s) applies a target temperature for a duration, maintaining a cooling period after the pulse, and providing single atoms of the element dispersed on the substrate after the one or more temperature pulses. The target temperature applied by the pulse is between 500 K and 4000 K, inclusive, and the duration is between 1 millisecond and 1 minute, inclusive.
Abstract:
A water sterilization device includes: (1) a conduit including an inlet to provide entry of untreated water and an outlet to provide exit of treated water; (2) a porous electrode housed in the conduit and disposed between the inlet and the outlet, the porous electrode including a porous support and nanostructures coupled to the porous support; and (3) an electrical source coupled to the porous electrode.
Abstract:
Organic light-emitting diodes (OLEDs) comprising at least one nanostructure-film electrode, and fabrication methods thereof are discussed. The nanostructure-film is preferably transparent, and may be deposited on a preferably-transparent substrate using a variety of techniques. A different material may be used to planarize the nanostructure-film and/or otherwise improve OLED performance.
Abstract:
In some embodiments, a material comprises a contiguous block of chemically-modified wood infiltrated with an index-matching polymer. The contiguous block has a first section that is substantially transparent to light and a second section that is translucent or opaque. The first section can have a lower lignin content than the second section. Alternatively, the first section can have a chromophore state altered from that of the wood in its natural state, and the lignin in the second section can retain a chromophore state of the wood in its natural state. In some embodiments, a material comprises a section of wood chemically-modified such that chromophores of lignin within the wood in its natural state are altered or removed, and the section retains at least 70% of the lignin of the wood in its natural state. Methods for forming such materials are also disclosed.
Abstract:
One or more reactants are flowed into thermal contact with a heating element in a reactor for a first time period. During a first part of a heating cycle, the one or more reactants are provided with a first temperature by heating with the heating element, such that one or more thermochemical reactions is initiated. The one or more thermochemical reactions includes pyrolysis, thermolysis, synthesis, hydrogenation, dehydrogenation, hydrogenolysis, or any combination thereof. The first heating element operates by Joule heating and has a porous construction that allows gas to flow therethrough. During a second part of the heating cycle, the one or more reactants are provided with a second temperature less than the first temperature, for example, by de-energizing the heating element. A duration of the first time period is equal to or greater than a duration of the heating cycle, which is less than five seconds.

Abstract:
We disclose a method for making an optically transparent, electrically conductive nanostructure film, comprising coating a dispersion or a solution comprising a nanostructure selected from the group consisting of carbon nanotubes, fullerenes, graphene flakes/sheets, nanowires, and two or more thereof on a substrate. The film may also comprise a dopant in the dispersion or solution, as well as an encapsulant or topcoat.
Abstract:
Naturally-occurring cellulose-based material, such as wood, bamboo, grass, or reed, can be subjected to one or more chemical treatments to remove at least some lignin therefrom. The resulting partially-delignified material can be partially dried or fully dried and then rehydrated to yield a moldable cellulose-based material. The moldable material can be formed from a substantially flat planar configuration into a non-planar three-dimensional configuration. Once formed into a desired configuration, the moldable material can be fully dried to set its shape, thereby forming a rigid molded piece. In some embodiments, the molded piece can be used as a structural material, for example, to form a load-bearing structure or part of a composite load-bearing structure.
Abstract:
A piece of natural plant material is subjected to one or more chemical treatments to remove substantially all lignin therefrom, thereby allowing the extraction of delignified, cellulose-based fibers. For example, the natural plant material can be a grass, such as bamboo or gladiolus. Subsequent drying of the extracted fiber densifies the structure, yielding improved mechanical properties. In some embodiments, the extracted fibers can be used, either alone or in combination with other materials, as a structural material. For example, the extracted fibers can be embedded within, infiltrated with, coated by, or otherwise combined with a polymer or concrete to form a composite material.
