A new type of cavitation damage has been observed on the turbines installed at the Three Gorges Power Station despite no cavitation detected during model tests. Metallurgical and fluid dynamic analysis suggests that this cavitation is triggered by boundary-layer turbulent production; the damaged (...
A new type of test facility for simulating accelerated cavitation damage is described. The facility consists of a rotor with a material specimen attached at the periphery in such a manner that there is repeated impact with a column of liquid droplets during high-speed rotation of the specimen. ...
A cavitation bubble is formed in the lubricant between the oil-attracting (yellow) and the oil-repellent surface (black). When used as a buffer, it might reduce wear. Credit: KIT Researchers have discovered a so far unknown formation mechanism of cavitation bubbles by means of a model calcula...
Our review aims to provide a current view of the use of focused ultrasound, and particularly SDT, in the management of GB, starting with their mechanism of action in vitro and in animal models and ending with current or future clinical trials, exploring the limitations and potential of such ...

pathogenic mycobacteria may also coopt the host autophagic machinery to break through the plasma membrane and depart from their host cells through an F-actin-based vacuolar compartment termed an “ejectosome”, which is proposed to be a nonlytic cell-to-cell bacterial transmission mechanism.87,88Fu...
remote magnetic steering can be employed to guide microbes configured as an imitation microrobot body toward the desired location. This biohybrid technique accelerates the arrival of drug delivery systems at the target location, reducing the threat of sanction by the reticuloendothelial mechanism [92]....
