Localization of air leaks by soap bubble

Journal of Thoracic Disease, 2019
Prolonged air leak (5 days or more) is the most frequent complication after major lung resection. The main reasons for prolonged air leak include lung tissue fragility due to emphysematous lung formation, impaired wound healing, and overlooked air leak points.

Large‐Scale and Cost‐Effective Fabrication of Ultra‐Thin, Biodegradable Microelectrode Arrays and Pressure Sensors Using Laser Micromachining

Advanced Materials Technologies, EarlyView.
A mask‐free and cost‐effective UV‐pico‐second laser‐based microfabrication method is proposed to fabricate large‐area biodegradable microelectrode arrays and pressure sensors. These devices demonstrate low impedance, good conformability, excellent biocompatibility, and rapid degradation, providing a new route for next‐generation transient electronics ...

Hierarchical Multi‐Material Architectures With Gradient Design for Dynamic‐Range Flexible Tactile Sensing

Advanced Materials Technologies, EarlyView.
Hierarchical multi‐material TPMS lattices are engineered as flexible tactile sensors by combining soft and stiff elastomeric layers with a conformal conductive coating. The bilayer architecture delivers sensitivity at low pressures while maintaining a broad detectable range under large loads, enabling reliable pressure and vibration monitoring for ...

High Throughput Aerosol Jet Printing to Operationalize High Aspect Ratio Patterning

Advanced Materials Technologies, EarlyView.
High‐throughput aerosol jet printing poses distinct limiting mechanisms to the printing process. These include rapidly changing ink chemistries, atomization instabilities, and liquid‐phase spreading. The combination of in‐line heating, process monitoring, and traditional optimization procedures enables rapid printing of high‐aspect‐ratio structures ...

Geometry and Motion Characteristics of Bubbles Released in Liquid Cross Flow

Journal of Applied Fluid Mechanics, 2019
To investigate the characteristics of the bubbles trapped in liquid cross flow, air was injected into flowing water circulated in a closed loop. High speed photography was used to record bubble images instantaneously.

Microfluidic Droplet Plate Preserving Single Human Induced Pluripotent Stem Cell‐Derived Cardiomyocytes Morphology and Function

Advanced Materials Technologies, EarlyView.
We introduce a novel method combining microfluidics, optogenetics, and human induced pluripotent stem cell (iPSC) technology to encapsulate single iPSC‐derived cardiomyocytes (iPSC‐CMs) in an optimal environment for functional characterization. This method enables direct genotype‐phenotype correlation for genetic studies and high‐throughput screening ...

Hybrid Additive Manufacturing of Highly Stretchable Bottlebrush Polymer Nanocomposites by Decoupled Extrusion and Photopatterning

Advanced Materials Technologies, EarlyView.
A Hybrid Direct Ink Writing–Digital Light Processing (HDD) strategy decouples material extrusion from shape definition, enabling high‐fidelity additive manufacturing of highly viscous, yield‐stress polymer nanocomposites. Excess ink acts as a removable, self‐supporting scaffold, allowing fabrication of unsupported and embedded complex architectures ...
