Aptamers are recognized in biology and biotechnology for use in binding to specific target molecules such proteins, peptides, or small molecules, with high affinity and specificity. Traditional use has focused on antibodies and related cell chemistry. However, these short nucleic acid strands, typically DNA or RNA with other chemical base modifications, may be used for gathering and collection of various molecular substances. A method of biomining an earthborn substance binds and sequesters rare earth elements by identifying an earthborn, target substance sought for mining, and determining a binding aptamer having an affinity for the target substance. A nucleic acid strand is generated to include the binding aptamer, and is introduced into a cellular organism for binding with the target substance. Following binding of the nucleic acid strand with the target substance, separation of target substance occurs for collection of the target substance.

A reflectional ultrasound device and an acoustic medium for interference and artifact mitigation allows alternative orientation of ultrasound probes for aligning the probe with a sensing surface, a complementary cannula or needle or other position or angle offset from the intended imaging target. A gelatin or similar firm, non-fluid but sound-permeable material holds a shape for passing an ultrasound imaging signal from a transducer or emitter to an acoustic reflector for indirectly focusing onto an imaging target. Cumbersome or unreliable fluid containment is avoided, and the problematic movement of gel substances prone to air infiltration and inconsistent placement are averted. Ultrasound imagers may be oriented for emission parallel to a patient imaging surface, and reflected into internal anatomical structures without substantial interference or signal loss.
An electrode placement device allows placement and fixation of electrocardiogram (EKG) electrodes. Proper adherence of electrodes to predetermined positions on the epidermal surface is facilitated by a plurality of elongated placement members extending from a base that align with the electrodes. Each electrode is biased against the patient sensing region, typically the chest of an EKG patient, by prongs flanking the electrode at the distal end of each of the placement members. Flanking prongs engage an outer perimeter of a flexible, skin placed electrode, while a gap between the prongs allows for a signal wire to the electrically conductive center. Problems with weak adhesion from sweat, dirt or poor adhesive are avoided by a modest biasing force imposed equally on all electrodes from manual pressure applied to the base.

A submersible, aquatic robot employs a deformable, tubular tail operable as a wave spring for directing movement through impelled fluid and controlled vectors based on directional orientation of the deformable tail. A central impeller in a toroidal housing forms a continuous fluid channel through the housing and tubular tail, while a series of tethers draws on opposed sides of the deformable tail for directing movement to one side or the other. The directed, tubular tail channels water for propulsion based on a vector defined by the directional tail. Wireless control of a fleet of aquatic robots can perform widespread sensory or dissemination tasks.

Lithium recycling from expended Li-Ion batteries occurs thought selective recovery of lithium charge materials from a recycling stream including transition metals used for the charge material. Li recovery performed using an organic acid-based approach including terephthalic acid (TPA), benzenetetracarboxylic acid (BTCA), and other organic acids results in highly selective lithium extraction, achieving minimal transition metal contamination in the extracted solution. A recycling stream including cathode materials from spent/end-of-life Li-ion batteries provides a source for recycled Li, as well as other cathode material metals. Combining the organic acid in a hydrothermal reactor followed by filtration separates transition metal oxides from a lithium salt solution. The lithium salt may be recrystallized by acetone and dried to a powder consistency. Lithium carbonate is then recovered by sintering, and further filtered for recovering battery grade recycled Li.

An aptamer having an affinity for contaminants or pollutants such as toxic metals and industrial chemicals may be introduced by a biocompatible delivery mechanism such as a DNA or RNA strand to which the aptamer is attached. The delivery mechanism delivers the aptamer, either as a direct nucleic acid sequence or expressed in a cell as a probiotic. When delivered as a prophylactic to the gastrointestinal tract (orally) as an aptamer or expressed within a probiotic cell, this would prevent absorption of metals and would thus reduce or eliminate the need for chelation therapy and thereby reduce disease burden. When used therapeutically, it could be ingested, or injected intravenously. Once bound, the toxic metals are expelled through normal gastrointestinal or urinary processes.

METHOD AND APPARATUS FOR RECYCLING LITHIUM-ION BATTERIES
Cathode material from exhausted lithium ion batteries are dissolved in a solution for extracting the useful elements Co (cobalt), Ni (nickel), Al (Aluminum) and Mn (manganese) to produce active cathode materials for new batteries. The solution includes compounds of desirable materials such as cobalt, nickel, aluminum and manganese dissolved as compounds from the exhausted cathode material of spent cells. Depending on a desired proportion, or ratio, of the desired materials, raw materials are added to the solution to achieve the desired ratio of the commingled compounds for the recycled cathode material for new cells. The desired materials precipitate out of solution without extensive heating or separation of the desired materials into individual compounds or elements. The resulting active cathode material has the predetermined ratio for use in new cells, and avoids high heat typically required to separate the useful elements because the desired materials remain commingled in solution.
A laser drying apparatus efficiently directs laser energy at a target media in an industrial environment. Typical industries include food production, continuous paper and sheet goods, and other suitable porous articles where moisture content is abated. A laser passes through a lens or beam shaping element for directing the laser energy incident upon the target media for drying. A beam-shaped form is preferable for even energy distribution over an area of the target media. Focused, beam shaped laser energy provides more efficient energy transfer to the target media over conventional radiant and/or convection heating. Electrical sources may be selected from environmentally favorable generation sources. The laser energy penetrates the target media to a depth greater than conventional heating methods, and may be combined with complementary heating and drying sources, such as convective air streams or radiated heating for receiving an aggregate drying energy by the target media.

A flexible trace formed from a fluidic, conductive material deposited onto a flexible and stretchable substrate forms a stretchable and deformable circuit for implementations subject to bending and flexing such as soft robotics and textile application such as clothing. An encapsulation layer forms a convex vessel over the flexible trace, and additional circuit layers are accommodated on the encapsulation layer by forming an aperture in the encapsulation layer for defining a via, and depositing a trace on the encapsulation layer engaged with the aperture. Successive encapsulation layers may serve as successive substrate layers for additional traces deposition or printing, followed by a final encapsulation layer for fully enclosing the traces and any placed components. As the layers are deformable and stretchable, and the traces are a fluidic, conductive material, the entire structure is flexible and deformable without compromising the electrical continuity of the deposited traces and connected components.
An electrolyzer for gaseous production such as hydrogen gas includes an oscillating electrode driven at a natural frequency of the gaseous bubbles improves output by readily removing the gaseous bubble product from the electrode surface, thereby exposing greater electrode surface area for subsequent electrolysis reactions. A natural frequency of the gaseous product determines an oscillation frequency with which to drive the electrode accumulating the gaseous product, such as hydrogen bubbles, to agitate and release the bubbles which then rise to the surface of the liquid filled containment. Integrating oscillation logic for agitating the otherwise stationary electrode or cathode in a PEM water electrolyzer improves hydrogen production by readily evacuating the generated hydrogen to free up the electrode area for additional electrolysis reactions.

ROBOT-ASSISTED IMAGING AND SERVOING FOR INTRAOPERATIVE GUIDANCE
An intraoperative guidance approach for an image guided surgical robot performs intraoperative image registration and guidance based on a surgical target. A surgical imaging modality, such as US (ultrasound) or PA (photoacoustic), establishes a frame of reference based on a preoperative base imaging modality such as CT (computed tomography) or MRI (magnetic resonance imaging). A position reference of a surgical target, such as a tumor or neural structure, is established by the surgical imaging modality from the base imaging modality, computed based on a dense scan of the surgical region. Successive scans in the surgical image modality provide real-time guidance for a robotically actuated surgical instrument or probe based on the surgical target. An iteration of successive scans allows intramodal servoing concurrent with surgical instrument actuation towards a moving surgical target when a fixed surgical position in the frame of reference cannot be assured.

SYSTEM AND METHOD FOR UNDERACTUATED CONTROL OF INSERTION PATH FOR ASYMMETRIC TIP NEEDLES
A needle steering system and apparatus provides active, semi-autonomous control of needle insertion paths while still enabling a clinician ultimate control over needle insertion. A method and system controls the needle path as the needle is inserted by precisely controlling the rotation of the needle as it continuously rotates during insertion. This enables underactuated 2 degree-of-freedom (DOF) control of the direction and the curvature of the needle from a single rotary actuator. Control of the rotary motion is therefore decoupled from the needle insertion. The rotary motion controls steering effort and direction, while the insertion controls needle depth or insertion speed. In one implementation, the proposed method does not require constant velocity insertion, interleaved insertion and rotation, or known insertion position or speed. The insertion may be provided by a robot or other automated method, may be a manual insertion, or may be a teleoperated insertion.

A nonuniform sampling device and technique and an offset immune luminescent lifetime estimation provides for sensing a gaseous presence and magnitude such as O2 levels or concentration. The partial pressure of O2 closely correlates with the lifetime of the luminescence quenched by O2. Lifetime measurements are preferred over intensity measurements because of their robustness to factors such as variations in the optical path. The disclosed approach, implemented in 180 nm CMOS, features a specialized AFE (Analog Front End) that obtains the luminescent lifetime information with 1) low noise and 2) leverages time-gated excitation, removing the need for optical filters to extract the luminescent response from the excitation light. The lifetime (τ) is calculated using the time differences between equal voltage steps and 4) a measured mean error is as accurate as 0.3%.

Precise surface treatment and finishing of an enclosed, non-linear channel through a 3-dimensional printed, additively manufactured or machined part or workpiece results from insertion of a grinding wheel on a flexible shaft and controlling an orbital movement though rotational speed, grit selection and fluid viscosity of a liquid medium in the channel. Drive logic rotates the flexible shaft for controlled rotation as the orbital movement or pattern achieves controlled contact with the interior channel surface. Rotational contact by the grinding wheel removes material based on a grit size, while the orbit is controlled through the rotation, viscosity and grit size for achieving uniform coverage of the interior surface. An internal geometry, typically circular or elliptical, is preserved while attaining a smooth surface through precise material removal resulting from the controlled orbit.

SPLIT SOLE INDEPENDENTLY ADJUSTABLE LOAD-LIMITING FOOTWEAR
A force absorbing device for a footwear appliance includes a shoe upper and a shoe sole having a planar sole surface, such that forces between the shoe upper and planar sole surface in ground contact are absorbed by storage and controlled release of kinetic energy in an elastic or resilient field. A footwear article such as a shoe or boot includes a split-sole system that redefines a shoe sole as coplanar surfaces having a force mitigating interface for receiving sudden forces and effectively mitigating these forces by storing kinetic energy and releasing it over time. An elastic field in the force mitigation interface is defined by a resilient material adapted to deform in response to the received force. Frictional engagement between the upper and lower sole may also be augmented by surface characteristics such as dimples, voids and lubricants, in addition to interference engagement with an elastic field.

A carbon coating such as graphene formed on an article or component forms a reduced friction surface on the component. The graphene forms a superlubricity coating for mitigating friction against engaged, moving surfaces. A metallic component receives a graphene coating resulting from a high temperature biowaste treatment (HTBT) by surrounding the metallic component with a granular biowaste medium defining a carbon source, and heating the metallic component in the biowaste medium for diffusing carbon from the biowaste medium to aggregate on a surface of the component, thereby forming a graphene coating.

A recycling process for exhausted, end-of-life solar panels achieves substantial recovery of silicon and silver, as well as other materials, from a recycling stream of discarded solar panels. Agitation and shredding of the solar panels yield a granular mass, which can be separated by particle size to yield the silicon rich solar cell material. Leaching with a strong base such as sodium hydroxide draws the silicon into the leach solution. Filtration of the leach solution draws off the silicon-rich solution and allows filtration of other valuable materials such as silver. Addition of an acid such as hydrochloric acid to the leach solution then precipitates the silicon into a nano silica powder of in the form of high purity silicon dioxide. The high purity silicon dioxide provides raw materials for recycled solar panels, lithium-ion batteries and other uses depending on the purity.

A generalized approach and methodology for addressing surface traversal and coverage of a 3 Dimensional (3-D) object receives a 3-D wireframe or similar Cartesian based representation, converts the 3-D representation to a u,v system or mapping. Often employed for texture mapping, u.v grid systems define a two dimensional form of an object, often referred to as “unfolding” of an object. Configurations herein define a u.v grid system directly on the 3-D object for computing a coverage path, typically an aggregation of raster passes to traverse an entire 3-D surface. From a robotic manipulator, a 3D freeform surface, and task constraints, the approach determines whether there exists a feasible continuous motion plan to cover the surface, and if so, produces a uniform coverage path that best satisfies task constraints resulting from the physical object and robot kinematics.

Nanoimprint lithography forms a microfeature array on a substrate responsive to inkjet printing techniques for high resolution printing of circuit elements and other features with highly accurate fidelity to predetermined boundaries. The microfeature array is defined by micropillars formed between intersecting microchannels in the substrate. The micropillars are responsive to a sequence of ink droplets in a highly controlled and predictable manner based on the droplet volume, droplet spacing and temperature. The flow of liquid ink is restrained by the micropillars for pinning the ink for avoiding uncontrolled ink flow as occurs on a flat surface. Subsequent layers of deposited ink tend to follow pining of previous layers, allowing an iterative buildup of layers for forming a trace of sufficient thickness and a high aspect ratio allowing traces extending above the depth of the microchannels for aiding communication with surface mount components.

A modular building system includes a joint for interconnecting a network of struts in a tetrahedral arrangement for forming a structural component supporting a floor, ceiling or post. The interconnected struts have a uniform length and join together with other struts at a predetermined angle defined by the joint. Once connected, the struts and joints form a tensioned network of a load bearing surface or post, where the members are in a tensioned arrangement at an equilibrium. External forces, such as moving loads, winds, and rain tend to spread the loads across the network of tensioned members, temporarily resulting in compression along some of the rigid struts. Panels join the strut network or lattice by load caps secured to the joints for receiving triangular panels matching the joint spacing.

A recycling and waste management process receives municipal solid waste (MSW) with substantial organic content to form a self-sustaining Hydrothermal Mineralization (HTM) process based on Supercritical Water Oxidation (SCWO) to receive supercritical steam and carbon dioxide with potential for electrical generation before forming calcium carbonate suitable for concrete production. Hydrothermal mineralization (HTM) provides a rapid elimination of organic wastes while simultaneously producing a non-emissive and thermally stable cement additive to act as a carbon sink. Hydrothermal mineralization (HTM) provides a rapid disposal pathway for organic wastes, a green source of electricity and a final product that can be coupled with traditional and alternative cement productions to reduce carbon footprints of cement production.
Cathode material from exhausted lithium ion batteries are dissolved in a solution for extracting the useful elements Co (cobalt), Ni (nickel), Al (Aluminum) and Mn (manganese) to produce active cathode materials for new batteries. The solution includes compounds of desirable materials such as cobalt, nickel, aluminum and manganese dissolved as compounds from the exhausted cathode material of spent cells. Depending on a desired proportion, or ratio, of the desired materials, raw materials are added to the solution to achieve the desired ratio of the commingled compounds for the recycled cathode material for new cells. The desired materials precipitate out of solution without extensive heating or separation of the desired materials into individual compounds or elements. The resulting active cathode material has the predetermined ratio for use in new cells, and avoids high heat typically required to separate the useful elements because the desired materials remain commingled in solution.

An aptamer having an affinity for toxic metals such as lead is introduced by a biocompatible delivery mechanism such as a DNA or RNA strand to which the aptamer is attached. The delivery mechanism delivers the aptamer, either as a direct nucleic acid sequence or expressed in a cell as a probiotic. When delivered as a prophylactic to the gastrointestinal tract (orally) as an aptamer or expressed within a probiotic cell, this would prevent absorption of metals and would thus reduce or eliminate the need for chelation therapy and thereby reduce disease burden. When used therapeutically, it could be ingested, or injected intravenously. Once bound, the toxic metals are expelled through normal gastrointestinal or urinary processes.

The systems are capable of a continuous operation at normal mammalian temperature and pH, thereby removing a need to cool down the algae growth medium and/or heat up the algae growth medium for a treatment of algae or for a replenishment of algae.
A photoacoustic (PA) sensor device has a localization feature that defines a position of the sensor or scan information with a coordinate frame defining relative positions a scanned specimen and sensor information of other imaging planes of the scanned specimen. The coordinate frame is defined by positional information from localization markers at a known offset from the sensor, or from position signals from a robotic actuator driving the sensor. A processor coalesces the sensor information and positional information to reconstruct a 3-dimensional rendered structure by stitching together the sensor information to form a continuous rendering. Stitching may include adjacent imaging planes at an angular offset due to a varied pose of the sensor, and/or adjacent images over a lateral area too large for a single scan or imaging plane to capture.

A storage and monitoring device for red blood samples in storage for donation (blood bank) and research. Stored blood can be susceptible to degradation, most often from a phenomenon known as ice nucleation. Accurate detection and identification of relevant factors causing ice nucleation can determine healthy samples of stored blood, and identify storage factors that promote storage longevity. A photodetection approach directs an illumination source and photometer on opposed sides of a blood containing vessel for measuring an illuminance affected by hemoglobin released from ruptured cells. Hemoglobin released from ruptured cells reduces light passage though the sample to indicate unusable samples. An accelerometer and temperature sensor measure the physical and temperate factors correlating with the detected cell degradation to determine storage criteria for extending blood longevity.

A carbon-negative Engineering Structural Material (ESM) has a compressive strength approaching that of concrete and relies on a carbon-absorbing enzyme for crystalline formations formed cooperatively with a porous structure to achieve load-bearing properties. A tough scaffold forms through capillary suspension, a technique that utilizes capillary forces to concentrate particles in a liquid matrix. Carbonic anhydrase, a zinc-containing enzyme extracted from bovine erythrocytes, is harnessed to grow mineral materials, and the capillary suspension is used to create a construction material, including sand and a polymer. This combination enables the incorporation of precipitated calcium minerals into the structure, resulting in the development of water-resistant and load-bearing construction materials.
A packed bed photochemical reactor ensures a consistent and effective irradiation of light to a reactant volume passed through a reactor. The reactor arranges miniaturized illumination elements such as LEDs in a packed bed arrangement with predetermined gaps or passages between. Fluid in communication with the packed bed flows between these gaps, ensuring a minimum distance to an irradiation source defined by the LEDs. Each LED is wirelessly powered from an inductive field through the reactor from an adjacent coil or electrical source. The inductive field wirelessly powers each of the illumination elements to ensure that the reactant in the passing fluid flow receives a consistent quantity of irradiation energy at the wavelength prescribed by the LED. In this manner, beneficial treatment rates allowing large volumes of reactant can be ensured based on the flow rate through the reactor.

A carbon coating such as graphene formed on an article or component forms a reduced friction surface on the component. The graphene forms a superlubricity coating for mitigating friction against engaged, moving surfaces. A metallic component receives a graphene coating resulting from a high temperature biowaste treatment (HTBT) by surrounding the metallic component with a granular biowaste medium defining a carbon source, and heating the metallic component in the biowaste medium for diffusing carbon from the biowaste medium to aggregate on a surface of the component, thereby forming a graphene coating.
