A method of recycling fiber reinforced polymers includes grinding used fiber reinforced polymers material to produce ground particles, functionalizing the ground particles to produce functionalized particles, dispersing the functionalized particles into a base resin, dispensing the resin with functionalized particles into one or more layers of continuous fiber mats, molding the resin with functionalized particles and the continuous fiber mats into a form of a desired part, and curing the form to produce the part. The used fiber reinforced polymer materials may be carbon fiber reinforced polymers or glass fiber reinforced polymer materials.

A 3D printing system and methods to selectively pattern dense feedstock based on selective inhibition sintering (SIS). A sintering selectivity agent (inhibitor or promoter) is selectively deposited on a build layer according to the pattern boundary. When the layers are built-up and the part is sintered, the inhibited region remains unbound, thus defining the edge of the part. The material contain powder embedded in cohesive binder that make the adjacent layer adhere together. The build process involves forming the sheets of dense feedstock embedded binder, followed by depositing ink to promote selective sintering onto the layer. Once the build is complete, the process continues with the binder removal, sintering and finishing processes.

System and method for high throughput additive manufacturing of sintered parts with low anisotropy

A stressed substrate for transient electronic systems (i.e., electronic systems that visually disappear when triggered to do so) that includes one or more stress-engineered layers that store potential energy in the form of a significant internal stress. An associated trigger mechanism is also provided that, when triggered, causes an initial fracture in the stressed substrate, whereby the fracture energy nearly instantaneously travels throughout the stressed substrate, causing the stressed substrate to shatter into multiple small (e.g., micron-sized) pieces that are difficult to detect. The internal stress is incorporated into the stressed substrate through strategies similar to glass tempering (for example through heat or chemical treatment), or by depositing thin-film layers with large amounts of stress. Patterned fracture features are optionally provided to control the final fractured particle size. Electronic systems built on the substrate are entirely destroyed and dispersed during the transience event.

Stressed substrates for transient electronic systems

A catalyst having a porous support having at least one of thermally or electrically conductive particles bonded by a polymer, and enzymes embedded into pores of the porous support. A process of manufacturing an enzyme-embedded porous support includes forming solution of monomers, enzymes, a solvent, and at least one of electrically and thermally conductive particles, polymerizing the monomers by adding initiators to the solution, and evaporating the solvent to produce an enzyme-embedded porous support. A process of manufacturing an enzyme embedded porous support, includes mixing enzymes, at least one of electrically conductive or thermally conductive particles, and a polymer in a solvent, and evaporating the solvent.

A composition of matter has a fiber structure impregnated with a polymer, the polymer having dispersed functionalized particles chemically bonded to the polymer, wherein the functionalized particles contain one of either groups same as a precursor of the polymer, or groups reactive with a precursor. A composition of matter has a fiber structure impregnated with cured epoxy resin having dispersed functionalized particles chemically bonded to the cured epoxy, wherein the functionalized particles contain one of either groups same as the epoxy resin, or groups reactive with the epoxy resin.

A transient electronic device includes electronic elements (e.g., an SOI- or chip-based IC) and a trigger mechanism disposed on a frangible glass substrate. The trigger mechanism includes a switch that initiates a large trigger current through a self-limiting resistive element in response to a received trigger signal. The self-limiting resistive element includes a resistor portion that generates heat in response to the trigger current, thereby rapidly increasing the temperature of a localized (small) region of the frangible glass substrate, and a current limiting portion (e.g., a fuse) that self-limits (terminates) the trigger current after a predetermined amount of time, causing the localized region to rapidly cool down. The frangible glass substrate is engineered such that a stress profile produced by the rapid heating/cooling of the localized region generates an initial fracture force that subsequently propagates throughout the glass substrate, whereby sufficient potential energy is released to powderize the electronic elements.

Systems and methods for controlling and operating a hybrid vehicle having a high degree of hybridization are disclosed. A power flow control system predicts vehicle power demand to drive the hybrid vehicle based on changing conditions during operation of the hybrid vehicle. The power flow control system controls the power flow so as to provide power to drive the hybrid vehicle based on the predicted vehicle power demand, wherein the predicted vehicle power demand is greater than a maximum.

Today, energy requiring equipment commonly relies on batteries for power. The excessive weight and size of batteries severely limits their performance. Described herein is a lightweight portable energy system which includes an ultra-high capacity hydrolysable hydride gel cartridge for use in supplying hydrogen gas to hydrogen based energy generators. Hydrolysable hydride reactivity is controlled by tuning the amounts of hydrophilic and hydrophobic content in a polymer gel encapsulant of the cartridge.

One embodiment of the present invention provides an energy-asset control system for utilizing an energy asset to provide one of more modes of operation services. The system includes an economic optimizer configured to identify at least one mode of operation opportunity based on current and/or future market conditions; a prognostics module configured to perform a prognostic analysis associated with the mode of operation opportunity for the energy asset using an existing model, and determine a confidence level associated with the prognostic analysis; and an operation controller. The economic optimizer is further to configured to, in response to the prognostics module determining the confidence level exceeding a predetermined threshold, determine an expected profit of the mode of operation opportunity based on outcomes of the prognostic analysis; and optimize, over a predetermined time period, a usage of the energy asset based on the expected profit of the mode of operation opportunity.
