Abstract: A sound absorbing panel includes a cavity section having a plurality of resonant cavities and a front panel having a plurality of sets of openings. Each set of openings is configured to provide fluid communication between one of the plurality of resonant cavities and the environment. Each of the plurality of resonant cavities has different dimensions from the remaining plurality of resonant cavities such that each of the resonant cavities is tuned for a different frequency range. Each of the sets of openings can differ from the remaining sets of openings in opening size, length, and distance between openings.

Abstract: Embodiments relate to a flow loop system for estimating wellbore circulation density. The flow loop system includes an eccentric annulus structure having an inner eccentric pipe and an outer pipe. The inner eccentric pipe can be representative of a drill string in a wellbore. The outer pipe can be representative of the wellbore. The flow loop system includes a pressure sensor configured to measure pressure loss gradients of annular flows between the inner eccentric pipe and the outer pipe. The flow loop system includes a wellbore circulation density processing module configured to estimate the wellbore's bottomhole pressure based on the measured loss gradients of annular flows of fluid and solid particles, rotation of the inner eccentric pipe, and eccentricity of the inner eccentric pipe.

Abstract: The invention includes methods of forming electronic circuitry on a target surface using intense pulsed light-induced mass transfer (IPLMT) of metal nanoparticles (NPs) by applying a pliable mask to a target surface, coating a carrier film with metal NPs, mounting the carrier film to the target surface and over the pliable mask so that the pliable mask is sandwiched between the target surface and the metal NPs. and exposing the metal NPs to light energy to cause atoms of the metal NPs to evaporate and transport through openings of the pliable mask and condense on the target surface, producing a conductive pattern of condensed metal on the target surface. Certain implementations may utilize a kirigami-patterned pliable mask to enhance conformity to a freeform 3D target surface. In certain implementations, zinc (Zn) may be formed by IPLMT of Zn NPs to the target surface.

Abstract: The present invention generally relates to the generation of tunable coloration and/or interference from, for example, surfaces, emulsion droplets and particles. Embodiments described herein may be useful for generation of tunable electromagnetic radiation such as coloration (e.g., iridescence, structural color) and/or interference patterns from, for example, surfaces (e.g., comprising a plurality of microdomes and/or microwells), emulsion droplets and/or particles. In some embodiments, the surfaces, interfaces, droplets, and/or particles produce visible color (e.g., structural color) without the need for dyes.

Abstract: Tuning fracture hydraulic conductivity can be provided so that high hydraulic conductivity in high temperature zones and low hydraulic conductivity in low temperature zones can be defined in enhanced geothermal systems (EGS). Uniform thermal gradient along flow paths can be provided or defined to help provide such conductivity zones. Experimentation performed to evaluate embodiments showed that embodiments could prevent appearance of dominant flow paths between the wells and maintain high heat extraction rates. Embodiments can greatly increase cumulative heat extraction. Embodiments can also be provided for application solely to the injection wells. Other embodiments can position tuning agents between the wells and still help provide control of the fluid flow in the reservoir and enhance heat extraction.

Abstract: Embodiments of the systems can be configured to receive electromagnetic emissions of a substrate (e.g., a build material of a part being made via additive manufacturing) by a detector (e.g., a multi-spectral sensor) and generate a ratio of the electromagnetic emissions to perform spectral analysis with a reduced dependence on location and orientation of a surface of the substrate relative to the multi-spectral sensor. The additive manufacturing process can involve use of a laser to generate a laser beam for fusion of the build material into the part. The system can be configured to set the multi-spectral sensor off-axis with respect to the laser (e.g., an optical path of the multi-spectral sensor is at an angle that is different than the angle of incidence of the laser beam). This can allow the multi-spectral sensor to collect spectral data simultaneously as the laser is used to build the part.
