Abstract: The disclosure provides rechargeable lithium ion batteries comprising at least one lithium salt-graphite composite electrode. In particular, the disclosure provides a rechargeable “water-in-bisalt” lithium ion battery with a high potential where at least a portion of the lithium salt is phase separated from the aqueous electrolyte, and where the anionic-redox reaction occurs within the graphitic lattice.
Abstract: The approach disclosed herein is a process for non-equilibrium chemical and materials processing using the combination of non-equilibrium plasma, non-equilibrium multi-functional catalysis, a precisely programed heating and quenching (PHQ), and supersonic reaction quenching to dynamically change the chemical equilibrium and increase the yield and selectivity of the products. An important feature of the disclosed approach is to realize an efficient and high selectivity synthesis method of chemicals and materials by using non-chemical equilibrium, non-equilibrium catalysts, and non-equilibrium of excited states via active control of molecule excitation by low temperature hybrid plasma, dynamics of chemical reactions by programed heating and supersonic quenching, and the design of non-equilibrium catalysts by thermal shocks and plasma coupling to enable distributed and electrified chemical synthesis of hydrogen, ammonia, valued carbon and other chemical products at atmospheric conditions.

Abstract: The present disclosure provides a one-pot chemoenzymatic method for site-specific modification and conjugation of antibodies at their Fc glycan site to produce structurally well-defined antibody conjugates carrying defined drugs and other entities. The method is enabled by the discovery that certain endoglycosidases have the ability to both deglycosylate an antibody and to recognize selectively modified small disaccharide oxazolines for transglycosylation on antibodies without hydrolysis of the resulting products.

Abstract: A method of producing a carbon nanotube may include heating a convergent flow nozzle and a flow chamber of a carbon nanotube reactor, flowing a vaporized reactant stream through the nozzle and collecting a carbon nanotube product from an outlet of a heated flow chamber disposed downstream of the heated convergent flow nozzle. The vaporized reactant stream may include a carbon nanotube nucleation carbon source, a carbon nanotube growth carbon source, and a carbon nanotube catalyst precursor. The nozzle may have a nozzle contraction ratio of from 3:1 to 300:1.
Abstract: A laser system for generating a narrow linewidth semiconductor light beam includes a substrate, a gain chip affixed on the substrate and configured to amplify light beam, and an optical feedback photonic chip affixed on the substrate, optically coupled to the gain chip, and configured to output light beam, which has a narrow linewidth around a resonant frequency of the optical feedback photonic chip, to the gain chip.
Abstract: The present disclosure provides an accelerated AD model system for use in the diagnosis and prognosis of Alzheimer's disease (AD). The AD accelerated model system may also be used in screening assays for identifying therapeutic agents that correct, or alleviate, one or more of the cell culture phenotypes associated with the development of AD. Such phenotypes include, for example, increased tau phosphorylation, amyloid plaque accumulation, elevated levels of A?42 to A?40 ratio, increased cell death and cell cycle re-entry. The methods and compositions provided herein are based on the discovery that exogenously expressed progerin in neural progenitor cells leads to a robust and accelerated AD phenotype in said cells as they differentiate and that the modified and differentiated cells surprisingly produce factors which generate an aged environment (“aging factors”) for all the cells in their vicinity.
Abstract: A solid-state device includes a substrate with a stack of constituent thin-film layers that define an arrangement of electrodes and intervening layers. The constituent layers can conform to or follow a non-planar surface of the substrate, thereby providing a 3-D non-planar geometry to the stack. Fabrication employs a common shadow mask moved between lateral positions offset from each other to sequentially form at least some of the layers in the stack, whereby layers with a similar function (e.g., anode, cathode, etc.) can be electrically connected together at respective edge regions. Wiring layers can be coupled to the edge regions for making electrical connection to the respective subset of layers, thereby simplifying the fabrication process. By appropriate selection and deposition of the constituent layers, the multi-layer device can be configured as an energy storage device, an electro-optic device, a sensing device, or any other solid-state device.

Abstract: Disclosed herein are systems and methods for synthesizing a diamond using a diamond synthesis machine. A processor receives a plurality of images of a diamond during synthesis within a diamond synthesis machine, each of the plurality of images captured within a time period. The processor executes a diamond state prediction machine learning model using the plurality of images to obtain a predicted data object, the predicted data object indicating a predicted state of the diamond within the diamond synthesis machine at a time subsequent to the time period. The processor detects a predicted defect, a number of defects, defect types, and/or sub-features of such defects and/or other characteristics (e.g., a predicted shape, size, and/or other properties of predicted contours for the diamond and/or pocket holder) of the predicted state of the diamond. The processor adjusts operation of the diamond synthesis machine.

Abstract: Cellulose nanofibers (CNF) act as a dispersing agent to directly exfoliate graphite in an aqueous solution using sonication. The resulting suspension has graphite flakes, each having 2-20 monolayers, a relatively large lateral dimension, and a plurality of CNF decorating its surfaces and edges. The dispersing effect of the CNF allows the graphite-CNF suspension to be stored without degradation until desired use. The graphite-CNF suspension can be used to form various composite structures, such as by spraying, coating, pouring, extruding, or printing the suspension, and then drying the suspension. The resulting composite structures have improved tensile strength and toughness due to hydrogen bond interactions between the CNF and graphite.
