The shape of a small drop of liquid can be considered spherical, neglecting the effect of gravity. This drop can further be considered as two equal hemispherical drops put together due to surface tension. The forces acting on the spherical drop are due to the pressure of the liquid inside the drop, the pressure due to air outside the drop, and the force due to the surface tension acting on the two hemispherical drops. where γ corresponds to the surface tension. Recalling that the force per...

Source: Kerry M. Dooley and Michael G. Benton, Department of Chemical Engineering, Louisiana State University, Baton Rouge, LA Liquid-liquid extraction (LLE) is a separation technique used instead of distillation when either: (a) the relative volatilities of the compounds to be separated are very similar; (b) one or more of the mixture components are temperature sensitive even near ambient conditions; (c) the distillation would require a very low pressure or a very high distillate/feed...

A fast and reliable technique is proposed to control the shape oscillations of a single, trapped acoustic bubble that is based on coalescence technique between two bubbles. The steady-state, symmetry-controlled bubble shape oscillations allow analysis of the fluid flow generated in the vicinity of the bubble interface.

This study presents a methodology to prepare 3D, biodegradable, foam-like cell scaffolds based on biocompatible side-chain liquid crystal elastomers (LCEs). Confocal microscopy experiments show that foam-like LCEs allow for cell attachment, proliferation, and the spontaneous alignment of C2C12s myoblasts.
FAQs
Pressure and flow rate determine whether liquid moves smoothly or experiences conditions that encourage gas pockets. Maintaining controlled pressure and a suitable flow rate supports a stable liquid column, while sudden pressure changes can promote bubble formation. This matters because bubbles may change the delivered volume or pressure in a precision physics experiment.
Continuous liquid contact reduces interruptions in the liquid column where gas can become trapped. Minimizing exposed or unfilled portions of the injection path helps prevent air from entering the delivery route or receiving system. This control is particularly important when the experiment depends on consistent liquid volume, pressure transmission, or fluid movement.
Careful alignment keeps the liquid path consistent as material moves from the injection device into the receiving system. Gradual delivery also limits turbulence and abrupt pressure changes, both of which can disturb the liquid column. Together, these practices produce more controlled fluid motion and reduce bubble-related variation during measurement or observation.
A practical sequence is to minimize trapped air, establish liquid contact with the injection device, align the delivery path, and apply pressure gradually. The flow rate should remain controlled throughout transfer rather than changing abruptly. These measures help preserve a continuous liquid column as the liquid enters the container or experimental system.
This technique is useful when gas inclusions could interfere with the behavior being measured or observed. Relevant settings include syringe-based experiments, microfluidic channels, vacuum systems, and precision instrumentation. In these applications, controlling bubble entry supports reliable fluid handling, clearer optical observations, and more consistent pressure or volume conditions.
Gas inclusions can alter the apparent delivered volume, disturb pressure conditions, reduce optical clarity, and change how interfaces behave. Their effects can therefore extend beyond the injection step into measurement and interpretation. Preventing them is valuable when an experiment requires stable fluid control or depends on accurate imaging, pressure, or volume measurements.
