  2. Nanobubble - Wikipedia

    en.wikipedia.org/wiki/Nanobubble

    In 1994, a study by Phil Attard, John L. Parker, and Per M. Claesson further theorized about the existence of nano-sized bubbles, proposing that stable nanobubbles can form on the surface of both hydrophilic and hydrophobic surfaces depending on factors such as the level of saturation and surface tension.

  3. Sonoluminescence - Wikipedia

    en.wikipedia.org/wiki/Sonoluminescence

    The animal snaps a specialized claw shut to create a cavitation bubble that generates acoustic pressures of up to 80 kPa at a distance of 4 cm from the claw. As it extends out from the claw, the bubble reaches speeds of 60 miles per hour (97 km/h) and releases a sound reaching 218 decibels. The pressure is strong enough to kill small fish.

  4. Antibubble - Wikipedia

    en.wikipedia.org/wiki/Antibubble

    Submerged antibubbles of air surrounded by soapy water Cluster of antibubbles on the surface of soapy water. An antibubble is a droplet of liquid surrounded by a thin film of gas, [1] as opposed to a gas bubble, which is a sphere of gas surrounded by a liquid.

  5. Bubble sensor - Wikipedia

    en.wikipedia.org/wiki/Bubble_sensor

    Bubble sensors are used to detect the presence of bubbles in fluid-filled tubes. They play a vital role in many fields, including medical technology, process control, pharmaceuticals, and the petroleum industry. The most common type of sensors used are ultrasonic or capacitor based. Bubble sensor for Extracorporeal Blood Circuits

  6. Microbubble - Wikipedia

    en.wikipedia.org/wiki/Microbubble

    This distinguishes the microbubbles from surrounding tissues. Because gas bubbles in liquid lack stability and would therefore quickly dissolve, microbubbles are typically encapsulated by shells. The shell is made from elastic, viscoelastic, or viscous material. Common shell materials are lipid, albumin, and protein. Materials having a ...

  7. Bubble (physics) - Wikipedia

    en.wikipedia.org/wiki/Bubble_(physics)

    Air bubbles rising from a scuba diver in water A soap bubble floating in the air. A bubble is a globule of a gas substance in a liquid. In the opposite case, a globule of a liquid in a gas, is called a drop. [1] Due to the Marangoni effect, bubbles may remain intact when they reach the surface of the immersive substance.

  8. Prairie-Masker - Wikipedia

    en.wikipedia.org/wiki/Prairie-Masker

    The vessel with bubbles in it will "thud". [citation needed] The noise quieting of the Prairie screw works on a different principle. The principal noise problem with a screw is cavitation. The pressure behind the moving blade may become so low that it is less than the vapor pressure of water at that depth. This results in a water vapor bubble ...

  9. Air embolism - Wikipedia

    en.wikipedia.org/wiki/Air_embolism

    Gas embolism is a diving disorder experienced by underwater divers who breathe gases at ambient pressure, and can happen in two distinct ways: . Pulmonary barotrauma: Air bubbles can enter the bloodstream as a result of gross trauma to the lining of the lung following a rapid ascent while holding the breath; the air held within the lung expands to the point where the tissues tear (pulmonary ...
