Laser‐Assisted Phase Engineering of 2D MoS2 for Efficient Solution‐Processed Electronics

Advanced Materials, EarlyView.
Here, local laser‐assisted phase transition from solution‐processed phase‐pure 1T′ to 2H MoS2 is shown to critically depend on the irradiation atmosphere. While processing in air leads to damaged insulating regions, inert conditions yield semiconducting 2H domains, enabling direct field‐effect transistor patterning with optimized lateral 1T′‐2H MoS2 ...

Acoustic Hypochlorite Activation in Simulated Curved Canals [PDF]

Journal of Endodontics, 2009
INTRODUCTION: It was the goal of this study to compare different NaOCl activation schemes regarding a desired and an untoward outcome. Ultrasonic tips and a currently marketed sonic system were used in conjunction with a 2.5% sodium hypochlorite solution.

Analysis of Measured and Simulated Supraglottal Acoustic Waves [PDF]

Journal of Voice, 2016
To date, although much attention has been paid to the estimation and modeling of the voice source (ie, the glottal airflow volume velocity), the measurement and characterization of the supraglottal pressure wave have been much less studied. Some previous results have unveiled that the supraglottal pressure wave has some spectral resonances similar to ...

Descriptors to Dynamics: A Materials and Device Perspective on in‐Materio Physical Reservoir Computing for Neuromorphic Edge Intelligence

Advanced Materials, EarlyView.
Intrinsic material dynamics are harnessed as computational resources for neuromorphic in‐materio physical reservoir computing. Defects, ionic motion, interfaces, percolation, geometry, and biasing shape transient states that provide fading memory, nonlinearity, and high‐dimensional projection for simple readout. A descriptor‐to‐dynamics framework links

Linear and nonlinear modeling of self-excited acoustic oscillations in a T-shaped thermoacoustic engine

AIP Advances, 2021
Branch tubes are often used in thermoacoustic engines (TAEs) for acoustic power extraction or acoustic field adjustment. Their roles, although critical for the performance of the thermoacoustic system, are not fully understood yet. To address this issue,

Directional Sources in Wave-Based Acoustic Simulation [PDF]

IEEE/ACM Transactions on Audio, Speech, and Language Processing, 2019
Volumetric wave-based acoustic simulation relies on the complete solution to the three-dimensional wave equation over a spatial grid. Detailed modeling of sources, however, requires interpolation over the grid, which is complicated by the directional character of the source itself.
