  • Patent number: 11684922
    Abstract: A microfluidic-based device and system is disclosed for the high-throughput intracellular delivery of biomolecular cargo to cells (eukaryotic or prokaryotic) or enveloped viruses. Cargo integration occurs due to transient membrane permeabilization by exposure to bulk acoustic waves (BAWs) transduced from surface acoustic waves (SAWs) generated by a rapidly oscillating piezoelectric substrate. In this approach, temporary pores are established across the cellular membrane as cells are partially deformed and squeezed or subject to shearing forces as they travel through the vibrational modes created within the microfludic channel(s) of the device.

  • Patent number: 10907366
    Abstract: A concrete vibrator can automatically change the rotational speed of a motor depending on the state of a vibrating tube. Under control by a controller, the concrete vibrator is operated in a normal mode in which the motor is supplied with driving power having a frequency to make the motor rotate at a rotational speed suitable for air bubble removal, or in an idling mode in which the motor is supplied with driving power having a frequency to make the motor rotate at a lower rotational speed than in the normal mode. The controller measures, per unit of time, a value of a current that is input to the controller or motor, compares a latest current value to a reference value calculated based on a past measurement value, and compares an absolute value of the comparison value to a threshold to grasp the state of the vibrating tube.

  • Patent number: 10166323
    Abstract: Systems and methods for cleansing blood are disclosed herein. The methods include acoustically separating undesirable particles bound to capture particles from formed elements of whole blood. After introducing the capture particles to whole blood containing undesirable particles, the whole blood and capture particles are flowed through a microfluidic separation channel. At least one bulk acoustic transducer is attached to the microfluidic separation channel. A standing acoustic wave, imparted on the channel and its contents by the bulk acoustic transducer, drives the formed elements and undesirable particles bound to capture particles to specific aggregation axes. After aggregating the particles, the formed elements exit the separation channel through a first outlet and are returned to the patient. The undesirable particles, bound to the capture particles, exit through a second outlet and can be discarded to saved for later study.

This method and apparatus utilize the breakup of the dispersed phase in a controlled fashion by periodically varying the pressure that drives the fluids so as to successfully generate emulsions with a good control over the size. The method and apparatus can be used for the formation of simple emulsion or double emulsion where a larger droplet contains one or more smaller droplets.

  • Publication number: 20130244242
    Abstract: Methods and systems for acoustically treating material using a continuous process in which material may be caused to flow in a continuous or intermittent fashion into/out of an acoustic treatment chamber where the material is exposed to focused acoustic energy. The methods and systems may be arranged to permit continuous processing for extended periods while an acoustic energy source operates at a relatively high power output. Treatment chambers may include features such as an acoustic window, a heat exchanger, inlet/outlet flow arrangements, an inspection window, insert elements that define a treatment volume size or shape, etc. Treatment system configurations relating to arrangements of a treatment chamber relative to an acoustic source and coupling medium, material flow paths, and others are provided.

  • Publication number: 20130214210
    Abstract: Provided is a process for producing a dispersion liquid of carbon nanotube aggregates in which the carbon nanotube aggregates are dispersed in a dispersion medium, comprising the two steps: (A) a step of adsorbing a dispersant to carbon nanotube aggregates by physical dispersion treatment in a dispersion medium to prepare a carbon nanotube paste with a particle size of 100 nm to 20 ?m resulting from partial dissociation of a mass of the carbon nanotube aggregates; and (B) a step of dispersing the carbon nanotube paste by ultrasonic dispersion treatment. A process for producing a dispersion liquid of carbon nanotube aggregates with reduced destruction and breakage of graphite structure of a carbon nanotube aggregate can be provided.

  • Patent number: 8496884
    Abstract: A stirring container in which liquid is contained is used in an analyzer for measuring a property of the liquid. The stirring container includes a recessed portion in which the liquid is held so that a meniscus is formed; and a sound wave generating unit disposed outside of a wall portion forming the recessed portion, and generates surface sound waves for stirring the liquid. The wall portion is configured so that a rising of the meniscus is lower than a rising of the meniscus formed by the liquid held in an assumed container whose cross section in a direction orthogonal to a depth direction of the recessed portion is the same as that of a circumscribed rectangle. The circumscribed rectangle is circumscribed about a portion, made of a same material as a part of the wall portion where the meniscus is formed, where the meniscus is formed in the relevant direction.

  • Publication number: 20130155802
    Abstract: Focused ultrasonic acoustic processing is used to prepare formulations particles ranging between approximately 10 nm and approximately 50 microns (e.g., between 1 micron and 20 microns), or between approximately 10 nm approximately 400 nm (e.g., between 10 nm and 100 nm). Formulations (e.g., nanoformulations) may include a suspension (e.g., nanosuspension), an emulsion (e.g., nanoemulsion) or another small particle system. Formulations may be used as delivery systems for therapeutic agents, e.g., a formulation may include a bioactive agent and a carrier compound such as a surfactant that encapsulates the bioactive agent.

  • Patent number: 8333893
    Abstract: A filtration separation method for waste resin containing highly radioactive uranium powder and device thereof is mainly used for the waste resin after water treatment process in a nuclear facility. The uranium powder contained in the waste resin is highly radioactive. Thus, prior to the treatment of the waste resin, it is necessary to filter and separate the highly radioactive uranium powder to reduce the radioactivity. It is to put the uranium powder containing waste resin into an underwater holding tank and withdraw the waste resin by an underwater pump into a uranium powder filtration box. Then the uranium powder filtration box is lifted by a hoist to move to an underwater ultrasonic cleaner. High-pressure water flushing is applied and followed by underwater ultrasonic cleaning. Then the cleaning water (containing precipitated uranium powder) from the ultrasonic cleaner is drained to uranium powder collection device.
