Combined surface acoustic wave and surface plasmon resonance measurement of collagen and fibrinogen layer physical properties

Sensing and Bio-Sensing Research, 2016
We use an instrument combining optical (surface plasmon resonance) and acoustic (Love mode surface acoustic wave device) real-time measurements on a same surface for the identification of water content in collagen and fibrinogen protein layers.

Surface acoustic wave propagation in monolayer graphene

, 2009
Surface acoustic wave (SAW) propagation is a powerful method to investigate 2D electron systems. We show how SAW observables are influenced by coupling to the 2D massless Dirac electrons of graphene and argue that Landau oscillations can be observed as ...

Local Thermal Conductivity Patterning in Rotating Lattice Crystals of Anisotropic Sb2S3

Advanced Functional Materials, EarlyView.
Microscale control of thermal conductivity in Sb2S3 is demonstrated via laser‐induced rotating lattice crystals. Thermal conductivity imaging reveals marked thermal transport anisotropy, with the c axis featuring amorphous‐like transport, whereas in‐plane directions (a, b) exhibit 3.5x and 1.7x larger thermal conductivity.

Preliminary Performance Assessment of the Wave Parameter Retrieval Algorithm from the Average Reflected Pulse

Remote Sensing
To obtain new information about surface waves, it is proposed to use an underwater acoustic wave gauge, and an assessment of its effectiveness can be performed using a numerical simulation and field experiment.

Surface acoustic wave coupling between micromechanical resonators

Communications Physics, 2022
As the size of mechanical resonators is decreased, their resonance frequencies increase and acoustic wave-like propagation in their substrate becomes important.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.
