Dissipation and detonation of shock waves in lipid monolayers

, 2018
Lipid interfaces not only compartmentalize but also connect different reaction centers within a cell architecture. These interfaces have well defined specific heats and compressibilities, hence energy can propagate along them analogous to sound waves ...

Real‐Time 3D Ultrasound Imaging with an Ultra‐Sparse, Low Power Architecture

Advanced Healthcare Materials, EarlyView.
This article presents a novel, ultra‐sparse ultrasound architecture that paves the way for wearable real‐time 3D imaging. By integrating a unique convolutional array with chirped data acquisition, the system achieves high‐resolution volumetric scans at a fraction of the power and hardware complexity.

Reduction of air flow rate for pulse-detonation-turbine-engine operation by water-droplet injection

Journal of Thermal Science and Technology, 2016
In this study, experiments on a pulse detonation turbine engine (PDTE) were conducted. The final goal of this work is the self-sustained operation of a PDTE system in which all of the air used for its operation is supplied by a turbine-compressor driven ...

Ultrasound‐Triggered Nanobubbles for Endothelial‐Targeted Drug Delivery in the Detection and Treatment of Doxorubicin‐Induced Cardiotoxicity

Advanced Healthcare Materials, EarlyView.
The DA/VTP‐NBs selectively recognized cardiac ECs damaged by DIC and achieved cell‐level targeted imaging. Then US‐triggered controlled release successfully enabled the release of DAPA within the DA/VTP‐NBs at the site of injury. This precise on‐demand drug release approach amplifies a series of localized therapeutic effects through the mtDNA‐mediated ...

Elastic-plastic coupled α→ω phase transformation of zirconium under shock loading: experiments and non-hydrostatic thermodynamic-based modeling

Journal of Materials Research and Technology
Modeling the martensitic transformation of solid materials under shock loading is still an unsolved problem. One of the key challenges is the effect of shear stress and elastoplastic coupling on the dynamic response.

Unveiling the Role of Curvature in Carbon for Improved Energy Release of Ammonium Perchlorate

Advanced Materials, EarlyView.
High‐curvature carbon materials identified via machine learning and simulation can enhance the heat release and combustion performance of ammonium perchlorate. ABSTRACT The catalytic role of carbon curvature in the thermal decomposition of ammonium perchlorate (AP) remains largely unexplored. To address this gap, this study employs machine learning and
