Numerical study of the effect of liquid compressibility on acoustic droplet vaporization

Ultrasonics Sonochemistry, 2021
In acoustic droplet vaporization (ADV), a cavitated bubble grows and collapses depending on the pressure amplitude of the acoustic pulse. During the bubble collapse, the surrounding liquid is compressed to high pressure, and liquid compressibility can ...

Bruxism and Stress: Ultrasonographic Masseter Muscle Assessment and Salivary Melatonin‐Cortisol Dynamics

Journal of Oral Rehabilitation, Volume 52, Issue 9, Page 1489-1495, September 2025.
ABSTRACT Background Bruxism is a parafunctional activity characterised by teeth grinding or clenching, often associated with stress and neurophysiological factors. Its aetiology is multifactorial, with recent studies emphasising neurotransmitters and hormonal imbalances, particularly melatonin and cortisol. This study assesses masseter muscle thickness

Decoupling Membrane Electrode Assembly Materials Complexity from Fuel Cell Performance through Image‐Based Multiphase and Multiphysics Modelling

Advanced Energy Materials, Volume 15, Issue 27, July 15, 2025.
A high‐resolution image‐based multiphase and multi‐physics modelling framework is developed to decouple structural changes in the membrane electrode assemblies of high‐temperature proton exchange membrane fuel cells. These changes are then digitally combined to show how morphological defects such as membrane pores, catalyst cracks, and phase migration ...

A coiled‐coil domain triggers oligomerization of MmpL10, the mycobacterial transporter of trehalose polyphleate precursor

FEBS Letters, Volume 599, Issue 12, Page 1682-1697, June 2025.
Most MmpLs transport lipids and glycolipids of the complex mycomembrane of mycobacteria. This study shows that MmpL10 from Mycobacterium smegmatis, the transporter of the trehalose polyphosphate precursor, harbors a coiled‐coil‐like extension. Biochemical and electron microscopy studies demonstrate that the coiled‐coil enables MmpL10 to trimerize.

Going from Inner‐Skinned to Outer‐Skinned Polyelectrolyte Multilayer Based Hollow Fiber Nanofiltration Membranes

Advanced Materials Technologies, Volume 10, Issue 8, April 17, 2025.
New negatively charged hollow fiber support membranes with an inverted porous structure are fabricated. These supports are coated with polyelectrolytes to form an outer‐skinned polyelectrolyte multilayer membrane. The membranes show a 3.8x increase in active membrane surface area compared to conventional inner‐skinned polyelectrolyte multilayer ...
