Abstract: This disclosure provides a battery including a cathode an anode positioned opposite the cathode. The anode includes a hybrid artificial solid-electrolyte interphase (A-SEI) layer encapsulating the anode. The hybrid A-SEI layer includes a first active component, a second active component disposed on the first active component, and a plurality of carbon-containing aggregates interwoven throughout the first and second active components and configured to inhibit growth of Li dendritic structures from the anode towards the cathode. A separator is positioned between the anode and the cathode. The cathode includes a porous carbon-based structure configured to expand in a presence of polysulfide (PS) shuttle within one or more portions of the battery. An electrolyte is dispersed between the anode and the cathode and in contact with both the anode and the cathode. The plurality of carbon-containing aggregates can include a polymer, which includes a cross-linked polymeric network.

Abstract: Disclosed apparatuses, systems, and materials relate to the disassociation of feedstock species (such as those in gaseous form) into constituent components, and may include an energy generator configured to provide a microwave energy. A first chamber defines a first volume and is configured to guide the microwave energy along the first chamber as a sinusoidal wave having an energy maxima at a point along the first chamber. A second chamber contains a plasma plume and is positioned substantially proximal to the first chamber, and is configured to enable propagation of the microwave energy through the first chamber and the second chamber such that the microwave energy demonstrates, at a radial center of the second chamber, a coaxial energy maxima configured to ignite the plasma plume contained in the second chamber. Carbon-containing materials may be formed by controlling flow parameters of the feedstock species into the first or second chamber.

Abstract: Methods include producing tunable carbon structures and combining carbon structures with a polymer to form a composite material. Carbon structures include crinkled graphene. Methods also include functionalizing the carbon structures, either in-situ, within the plasma reactor, or in a liquid collection facility. The plasma reactor has a first control for tuning the specific surface area (SSA) of the resulting tuned carbon structures as well as a second, independent control for tuning the SSA of the tuned carbon structures. The composite materials that result from mixing the tuned carbon structures with a polymer results in composite materials that exhibit exceptional favorable mechanical and/or other properties. Mechanisms that operate between the carbon structures and the polymer yield composite materials that exhibit these exceptional mechanical properties are also examined.

Abstract: A microwave energy source that generates a microwave energy is disclosed. The microwave energy source has an on-state and an off-state. A control circuit is coupled to the microwave energy source and includes an output to generate a control signal that adjusts a pulse frequency of the microwave energy. A voltage generator applies a non-zero voltage to the microwave energy source during the off-state. A frequency and a duty cycle of the non-zero voltage is based on a frequency and a duty cycle of the control signal. A waveguide is coupled to the microwave energy source. The waveguide has a supply gas inlet that receives a supply gas, a reaction zone that generates a plasma, a process inlet that injects a raw material into the reaction zone, and an outlet that outputs a powder based on a mixture of the supply gas and the raw material within the plasma.

Abstract: Pulsed radiation is generated at a power level that depends on a voltage level, frequency and duty cycle of a pulsed high voltage. A pulsing switch generates the pulsed high voltage from a high voltage and a pulse control signal. The pulsing switch has first and second bi-polar active switches connected in series between a high voltage conductor and a ground conductor. The pulsed high voltage is produced at a connection between the first and second bi-polar active switches when the first and second bi-polar active switches are repeatedly pulsed on and off to alternatingly connect the high voltage conductor and the ground conductor to a pulsed voltage output.
