The production of drops by the bursting of a bubble at an air liquid interface [PDF]
, 1982 The fundamental mechanism arising during the bursting of a bubble at an air-liquid interface is described. A single bubble was followed from an arbitrary depth in the liquid, up to the creation and motion of the film and jet drops. Several phenomena were

Advanced Functional Materials, EarlyView.MAGTWIST: A compact magnetic rotary actuator, enabling smooth, stepless rotation, and on‐demand locking. Inspired by peristalsis, a soft polymer belt generates a traveling‐wave, enabling 270° rotation when heated. Cooling stiffens the belt, locking it in position and enabling it to withstand high loads.

Advanced Functional Materials, EarlyView.A dual‐layer living hydrogel, ProΦGel, integrates bacteriophages and probiotics for synergistic wound infection therapy. The outer gelatin‐based matrix releases phages on demand in response to P. aeruginosa infections, while inner alginate beads sustain probiotic delivery.

Rock Breaking by Conical Pick Assisted with High Pressure Water Jet
Advances in Mechanical Engineering, 2014 In the process of hard rock breaking, the conical pick bears great cutting force and wear, and the cutting efficiency is lower. Thus different combination ways of water jet and conical pick were proposed to solve this issue; for instance, water jet ...

New Tehniques of Pressure Relief and Permeability Enhancement by Abrasive Jet in Coal Mine Roadways
Shiyou jixie, 2023 Pure water jet penetration in hard coal seams is deficient for low rock-breaking efficiency and complex operation.This paper presents two new techniques of pressure relief and permeability enhancement by deep penetration with abrasive jet and by radial ...
