Abstract: A system may include a circulation subsystem and a circuit coupled to the circulation subsystem. The circuit may provide one or more signals to control the circulation subsystem to circulate a treatment solution including one or more of microbubbles or nanobubbles in a selected ratio. In one aspect, the nanobubbles may include a first gas, and the microbubbles may include a second gas. In another aspect, the treatment solution may include a first percentage of nanobubbles and a second percentage of microbubbles. In another aspect, mechanical agitation can be applied to the solution on an object to assist in cleaning.

Abstract: A system may include a nanobubble generator that uses a shearing force applied by a fluid received through a fluid inlet and a negative pressure applied to an outlet by a pump to provide a vacuum-assisted shear flow nanobubble generator system. In some implementations, the system may include a nanobubble generator including a porous component including a chamber coupled to receive a gas and including a surface having a plurality of gas-permeable openings. The nanobubble generator may include an inlet and an outlet on opposing sides of the porous component to direct the fluid across the openings. The system may include a pump to apply a negative pressure to the outlet of the nanobubble generator. The negative fluid pressure and the fluid flow across the openings cooperate to form nanobubbles at low injected gas pressures, increasing the efficiency of production of nanobubble solutions with pressure sensitive gasses, such as ozone.

Abstract: A radiation sensor device may include at least one radiation sensor configured to capture radiation measurement data, a location circuit to determine physical location data, a clock to provide timestamp data, and one or more communication interfaces configured to communicate with a radiation mapping system through one or more of a communication network or a communications link. The device may include a processor configured to selectively control a frequency of operation of the one or more sensors to capture the radiation measurement data based on changes to the physical location data. The device may be configured to correlate the radiation measurement data to the physical location data and the timestamp and to determine an anomalous radiation measurement based on the radiation measurement data relative to background radiation data. The device may send an alert to the radiation mapping system in response to determining the anomalous radiation measurement.

Abstract: A multi-physics and multi-scale system and process to simulate imaging of hydrocarbon reservoirs using electromagnetic particles and electromagnetic tomography. Embodiments are applicable towards flood-front mapping and hydraulic fracture imaging. With respect to flood-front mapping, coated nanoparticles (or their software representation) may be injected. In case of fracture imaging, the contrast agents (or their software representation) may either be injected as proppants, fibers, or nanoparticles suspended in the solution.
