Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing

Advanced Materials, EarlyView.
Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.

Light‐Induced Entropy for Secure Vision

Advanced Materials, EarlyView.
This work realized a ternary true random number generator by exploiting stochastic traps emerging within multiple junction interfaces, and quantitatively validated the generation of high‐quality random numbers. Furthermore, it successfully demonstrated diverse applications, including AI‐resilient image security, thereby providing a valuable guide for ...

Soft Ionic and Electronic Triboelectric Nanogenerators: Toward Attachable and Implantable Biomedical Applications

Advanced Materials, EarlyView.
This review provides an overview of triboelectric nanogenerator (TENG)–based biomedical applications by classifying studies into electronic and ionic systems across attachable and implantable platforms. It summarizes key material choices, device structures, and working mechanisms that characterize current TENG‐based research, and outlines six future ...

Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

Advanced Materials, EarlyView.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

Non‐Invasive Brain Targeted Delivery of Cannabidiol for Alleviating Neuroinflammatory Disease

Advanced Materials, EarlyView.
The glucose‐functionalized nanoparticles (GNPs) are developed for the brain‐targeted delivery of cannabidiol (CBD). GNPs bypass the blood‐brain barrier (BBB) via glucose transporter‐1 (GLUT‐1) and release CBD in response to reactive oxygen species (ROS).

Standardized crush injury of the mouse median nerve

Journal of Neuroscience Methods, 2010
The employment of transgenic mouse models for peripheral nerve regeneration studies is continuously increasing. In this paper, we describe a standardized method for inducing a crush lesion in mouse median nerve using a non-serrated clamp exerting a crush compression force of 20.43 MPa for a duration of 30 s.

Endoneurial microenvironment and acute nerve crush injury in the rat sciatic nerve

Brain Research, 1990
In severe peripheral nerve ischemia in the rat, serial nerve blood flow (NBF) measurements have identified evidence of 'no reflow', a mechanism of continued fiber damage during reperfusion. It has been postulated that 'no reflow' also occurs in nerve compression due to direct mechanical or ischemic (if compression is prolonged) injury of microvessels ...

Laryngeal Nerve Crush for Spastic Dysphonia

Annals of Otology, Rhinology & Laryngology, 1979
Four patients with spastic dysphonia refractory to speech and phychiatric therapy were treated by crushing the recurrent laryngeal nerve. Vocal cord paralysis was produced in all patients. Vocal spasticity subsided in all patients. Vocal cord motion returned in four to six months.

THE DOUBLE CRUSH IN NERVE-ENTRAPMENT SYNDROMES

The Lancet, 1973
Abstract A comprehensive electromyographic study has been made of 115 patients with carpal-tunnel syndromes or lesions of the ulnar nerve at the elbow. In 81 cases there was electrophysiological evidence, often supported by clinical symptoms, of associated neural lesions in the neck.
