Ultrafast Vertical Organic Electrochemical Transistors With Ion‐Permeable Conductive Polymer Top Electrodes

open access: yesAdvanced Materials, EarlyView.
Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a

Theoretical analysis of transcranial magneto-acoustical stimulation with Hodgkin–Huxley neuron model

open access: yesFrontiers in Computational Neuroscience, 2016
Transcranial magneto-acoustical stimulation (TMAS) is a novel stimulation technology in which an ultrasonic wave within a magnetostatic field generates an electric current in an area of interest in the brain to modulate neuronal activities. As a key part

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

open access: yesAdvanced 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 ...

Multiphysical model of CMUT array based on modal decomposition and the Rayleigh integral

open access: yesSensing and Bio-Sensing Research
There is a high number of modeling techniques for calculation of characteristics of capacitive micromachined ultrasound transducers. Very few of them are capable of calculation of the acoustic field, especially when the number of cells in the array is ...

Controlling Radiative Phonons in the van der Waals Ferroelectric NbOI2

open access: yesAdvanced Materials, EarlyView.
Using a simple mirror geometry, this work demonstrates local‐density‐of‐optical‐states control of THz phonon emission in van der Waals ferroelectric NbOI2. By engineering the photonic environment, the phonon Q‐factor, linewidth, peak frequency, and emission intensity are reversibly tuned by over an order of magnitude, revealing radiative phonons as ...

Bioinspired Adaptive Surfaces for Intelligent Liquid Manipulation: Progressing From Passive and Active to Hybrid Strategies

open access: yesAdvanced Materials, EarlyView.
This review examines passive, active, and hybrid liquid manipulation strategies, highlighting hybrid approaches as an emerging route to reconcile energy efficiency with adaptive control. By actively reconstructing passive surfaces to store programmable interfacial energy, hybrid systems enable flexible yet low‐power liquid transport, with perspectives ...

Parameters for Acoustic Design in Auditorium

open access: yesInternational Journal of Recent Technology and Engineering (IJRTE), 2019
The clarity of communication in any auditorium is closely associated to the quality of acoustic treatment of that space. This quality is characterized by various parameters in acoustic designing. This research paper aims to explain the acoustical phenomenon and defects that becomes the basis of acoustical designing and material selection.
