Exceptional Electro‐Optic Coefficient Unlocked via Polarization Swaying in KNbO3 Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
We present the largest reported electro‐optic response in any material to date, guided by a new design principle that exploits ultralow coercive field polarization swaying enabled by low‐symmetry ferroelectric phases in monoclinic KNbO3 thin films for energy‐efficient classical and quantum photonic integrated circuits. ABSTRACT The electro‐optic effect

Preliminary evaluation of vector flow and spectral velocity estimation.

open access: yes, 2010
Spectral estimation is considered as the golden standard in ultrasound velocity estimation. For spectral velocity estimation the blood flow angle is set by the ultrasound operator.

Programming Neuromorphic Plasticity Through Ionic and Electronic Coupling in Organic Electrochemical Transistors

open access: yesAdvanced Functional Materials, EarlyView.
Neuromorphic plasticity in OECTs is governed by the post‐stimulus evolution of coupled ionic and electronic states. Semiconductor chemistry and morphology, electrolyte composition and interfaces, and device architecture regulate ion injection, transport, confinement, and release, shifting responses from rapidly relaxing STP to metastable memory and ...

Vector blood velocity estimation in medical ultrasound

open access: yes, 2006
Two methods for making vector velocity estimation in medical ultrasound are presented. All of the techniques can find both the axial and transverse velocity in the image and can be used for displaying both the correct velocity magnitude and direction ...

ENERGETIC CHARACTERISTICS OF THE SURFACE ELECTROMAGNETIC WAVE AT PLASMA-PLASMA INTERFACE IN MAGNETIC FIELD

open access: yesEast European Journal of Physics, 2014
Energetic characteristics of a surface wave at a plane plasma-plasma interface in an external magnetic field are studied. The dependencies of energy flow density and energy density on wave vector for different magnitudes of external magnetic field are ...

GDNF‐Enriched Small Extracellular Vesicle‐Loaded ROS‐Scavenging Hydrogel Promotes Neural Regeneration After Spinal Cord Injury

open access: yesAdvanced Healthcare Materials, EarlyView.
A glial cell line‐derived neurotrophic factor (GDNF)‐enriched small extracellular vesicle‐loaded reactive oxygen species (ROS)‐scavenging hydrogel integrates sustained neurotrophic delivery with local modulation of oxidative and inflammatory stress after spinal cord injury. The composite hydrogel improves local vesicle retention, protects neural tissue,

Measuring Blood Plasma Glutamine Levels Using a Nanopore‐Based Sensor

open access: yesAdvanced Healthcare Materials, EarlyView.
Glutamine (GLN) is a biomarker useful for predicting toxic ammonia accumulation. Here, we used a biosensor based on the Cytolysin A (ClyA) nanopore coupled with the GLN‐specific protein substrate‐binding domain 2 (SBD2) to demonstrate real‐time measurement of GLN in blood plasma, highlighting the potential for future point‐of‐care applications ...
