Absorption in Hydro-Acoustic Networks

, 2013
Water covers over 70% of the globe, yet our ability to communicate in the underwater environment is limited. Radio and light communication through water suffer from such major issues that acoustic waves are the dominant form of cable-free underwater communication, but themselves suffer from low bandwidth and poor signal quality.

Conformational Switching of Proteins on Material Surfaces Enabled by Peptide‐Oriented Adsorption

Advanced Functional Materials, EarlyView.
Responsive biointerfaces could be achieved using conformationally responsive proteins; however, their interconversion can be lost upon surface adsorption. Herein, we demonstrate that the incorporation a Au binding peptide into calmodulin allows for binding control on Au wherein the protein retains conformational switching. This capability was confirmed

Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems

Advanced Functional Materials, EarlyView.
Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...

Ultrabroadband sound control with deep-subwavelength plasmacoustic metalayers

Nature Communications, 2023
Controlling audible sound requires inherently broadband and subwavelength acoustic solutions, which are to date, crucially missing. This includes current noise absorption methods, such as porous materials or acoustic resonators, which are typically ...

Sound absorption by acoustic microlattice with optimized pore configuration [PDF]

The Journal of the Acoustical Society of America, 2018
The great progress in material science and nano-micro fabrication enables the applications of metamaterials with well-defined and well-organized microstructures for noise reduction. However, what intrinsic morphology of the metamaterial would result in optimum sound absorbing efficiency remains uncertain. This work presents a microlattice metamaterial,

3D Hydrodynamic Flow Lithography

Advanced Functional Materials, EarlyView.
ABSTRACT Continuous‐ and stop‐flow lithography are widely used to fabricate multi‐dimensional microstructures whose cross‐sectional morphology is dictated by the flow profile of multiple co‐flowing streams. Here, we introduce three‐dimensional hydrodynamic flow lithography (3D HFL), a platform for programmable generation of multi‐layered flow profiles ...

A Novel Drug‐Loaded Porous Parylene Electrode for Targeted Anti‐Inflammatory Therapy and Hearing Preservation in Cochlear Implantation

Advanced Healthcare Materials, EarlyView.
A porous parylene‐coated electrode loaded with dexamethasone was developed to reduce inflammation after cochlear implantation. In guinea pigs, the device provided sustained drug release, maintained biocompatibility, improved auditory brainstem response thresholds, and reduced inflammatory cell infiltration and TNF‐α expression.

A time-harmonic/time-domain hybrid approach based on displacement-based formulations to compute the absorbing coefficient in alpha cabins

Journal of Mathematics in Industry
In the automotive industry, the absorption coefficient of a porous material layer is usually measured in an alpha cabin, a reverberant chamber of reduced dimensions where the operational frequency range is limited and the absorbent sample size is ...
