The mucus clearance system is the dominant mechanical host defense system of the human
lung. Mucus is cleared from the lung by cilia and airflow, including both two-phase gas-liquid …

Coronavirus disease 2019 (COVID-19), due to infection by the severe acute respiratory
syndrome coronavirus 2 (SARS-CoV-2), is now causing a global pandemic. Aerosol …

Spray-drying is an inherently continuous and well-established industrial drying process. It
can accelerate manufacturing of biopharmaceuticals and vaccine products, resulting in both …

Surfactant-mediated wetting and spreading are ubiquitous. Understanding of these
phenomena in-depth allows precise tailoring of wetting performance which can contribute to …

The pulmonary surfactant (PS) is a complex mixture of lipids and proteins dispersed in the
aqueous lining layer of the alveolar surface. Such a layer plays a key role in maintaining the …

Marangoni spreading on thin films is widely observed in nature and applied in industry. It
has serious implications for airway drug delivery, especially in surfactant displacement …

Microswarms have shown great potential in biomedical applications at small scales due to
their features of wireless actuation and collective microrobotic behaviors. However …

Hypothesis The gradients in surfactant distribution at a fluid-fluid interface can induce fluid
flow known as the Marangoni flow. Fluid interfaces found in biological and environmental …

Spreading on the free surface of a complex fluid is ubiquitous in nature and industry, such as
drug delivery, oil spill, and surface treatment with patterns. Here, we report on a fingering …

The interfacial flow and mass transfer of multicomponent droplets remain an unsolved basic
problem, although multicomponent droplets are widely used in droplet microfluidics, fine …
