Acoustic wave propagation mechanism in the local stiffened structure of space station cabin using finite element method

open access: yesAIP Advances, 2022
Acoustic-based leakage detection and location in a spacecraft has attracted many researchers’ interest. Due to the fact that wave propagation through the stiffened structure is too complicated to be comprehensively understood, current leakage detection ...

Engineering a Sonotherapeutic RBC Membrane‐Derived Nanoparticle Platform for the Treatment of Liver Cancer

open access: yesAdvanced Functional Materials, EarlyView.
Herein, an RBC membrane‐derived nanoparticle (CMN‐ICG) is engineered to efficiently deliver a sonosensitizing agent, indocyanine green (ICG), for sonotherapy of hepatocellular carcinoma (HCC). CMN‐ICG exhibits excellent cytocompatibility, significantly enhances hepatocyte uptake, and produces excessive reactive oxygen species (ROS) upon ultrasound ...

Numerical Simulation Study on the Response of Dipole Acoustic Logging to Borehole Enlargement

open access: yesCejing jishu
Affected by factors such as the uneven distribution of in-situ stress and the development of fracture zones, borehole enlargement often occurs in Shunbei Ordovician carbonate formation, which leads to the multi-solution nature of interpretation and ...

Nonlinear acoustic–gravity waves

open access: yesJournal of Plasma Physics, 2009
AbstractPrevious results on nonlinear acoustic–gravity waves are reconsidered. It turns out that the mathematical techniques used are somewhat similar to those already adopted by the plasma physics community. Consequently, a future interaction between physicists in different fields, e.g. in meteorology and plasma physics, can be very fruitful.

Deterministic hBN Bubbles as a Versatile Platform for Studies on Single‐Photon Emitters

open access: yesAdvanced Functional Materials, EarlyView.
Single‐photon emitters (SPEs) in hBN are promising for quantum technologies; however, in exfoliated samples their activation is required, limiting reproducibility of previous studies. This work introduces a large‐area MOVPE‐grown hBN platform that hosts SPEs without prior activation.

Nanoscale diffractive probing of strain dynamics in ultrafast transmission electron microscopy [PDF]

open access: yes, 2017
The control of optically driven high-frequency strain waves in nanostructured systems is an essential ingredient for the further development of nanophononics. However, broadly applicable experimental means to quantitatively map such structural distortion

Fluorine‐Free Soft Nanocomposites for High‐Speed Liquid Impact Repellence

open access: yesAdvanced Functional Materials, EarlyView.
Fluorine‐free soft nanocomposite coatings are developed using silicone oil‐mediated mechanical‐stiffness control, enabling ‘dry’ liquid‐repellent surfaces that resist high‐speed water jet impacts up to ∼60 m/s. By tuning nanoparticle loading and oil content, the coatings also achieve >90% optical transparency, amphiphobicity with impact resistance to ...

Signatures of Emerging Subsurface Structures in Acoustic Power Maps

open access: yes, 2010
We show that under certain conditions, subsurface structures in the solar interior can alter the average acoustic power observed at the photosphere above them.

Conductive Bonding and System Architectures for High‐Performance Flexible Electronics

open access: yesAdvanced Functional Materials, EarlyView.
This review outlines bonding technologies and structural design strategies that support high‐performance flexible and stretchable electronics. Bonding approaches such as surface‐activated bonding and anisotropic conductive films, together with system‐level architectures including buffer layers and island‐bridge structures, possess distinct mechanical ...

Directional transmission of ultra-high frequency acoustic signals based on metamaterial structure

open access: yesAIP Advances, 2019
Cell photoacoustic detection of acoustic signals has serious problems of transmission loss and difficulty in acquisition. Based on the acoustic transmission characteristics of acoustic supermaterials, the acoustic wave directional transmission model is ...
