MXene/PEDOT Functional Coatings on Flexible Microelectrode Arrays for Multianalyte In Vivo Neurochemical Sensing and Electrophysiology

Advanced Functional Materials, EarlyView.
A MXene/PEDOT coating enables multimodal functionality and dual‐analyte detection of dopamine and serotonin in flexible microelectrode arrays while enhancing electrophysiological recording quality. The anti‐fouling, low‐impedance interface overcomes key limitations of conventional coatings, providing a robust and versatile platform to investigate the ...

Impact of Screw and Edge Dislocation on the Thermal Conductivity of Nanowires and Bulk GaN

, 2017
We report on thermal transport properties of wurtzite GaN in the presence of dislocations, by using molecular dynamics simulations. A variety of isolated dislocations in a nanowire configuration were analyzed and found to reduce considerably the thermal ...

Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells

Advanced Materials, EarlyView.
This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...

Dynamics analysis of pilot's upper limb manipulation process

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2018
A 6-degree-of-freedom (DOF) model of a pilot's upper limb is established in this study. A kinematics analysis is performed by using the screw theory and the product of exponential formula.

First-principles data for solid-solution strengthening of magnesium: From geometry and chemistry to properties

, 2010
Solid-solution strengthening results from solutes impeding the glide of dislocations. Existing theories of strength rely on solute-dislocation interactions, but do not consider dislocation core structures, which need an accurate treatment of chemical ...

A Novel Family of Parallel Mechanisms With Synchronous Telescopic Parallelograms

IEEE Access, 2019
A novel synchronous telescopic parallelogram mechanism with movement realized by a belt drive is proposed, from which a compound kinematic limb is derived. According to the configuration derivation, a class of two-translation (2T), three-translation (3T)
