Opportunities for 2D‐Material‐Based Multifunctional Devices and Systems in Bioinspired Neural Networks

Small, EarlyView.
Bio‐inspired computing offers a route to highly energy‐efficient artificial intelligence. The unique physical properties of two‐dimensional (2D) materials can further enhance such computing approaches. This perspective highlights recent developments in 2D materials‐based neuromorphic devices and discusses future opportunities for integrating such novel

Biological knowledge-slanted random forest approach for the classification of calcified aortic valve stenosis

BioData Mining, 2021
Background Calcific aortic valve stenosis (CAVS) is a fatal disease and there is no pharmacological treatment to prevent the progression of CAVS. This study aims to identify genes potentially implicated with CAVS in patients with congenital bicuspid ...

MOF‐Derived Bi2WO6/MXene Ternary Heterojunction as a Highly Efficient Piezocatalyst for Ultrasound‐Driven Hydrogen Evolution and Oxygen Evolution Reaction

Small, EarlyView.
A Bi‐MOF‐derived Bi‐rich Bi2WO6/Bi3.84W0.16O6.24 ternary heterojunction with Ti2C MXene is developed as a highly efficient piezocatalyst. Ultrasound‐driven charge separation via a dual‐phase oxide and conductive MXene electron highway achieves an H2 evolution rate of 1450.1 µmol g−1h−1 through an unconventional •OH‐mediated pathway, with concurrent ...

Intima-media thickness of the descending aorta in patients with bicuspid aortic valve

International Journal of Cardiology: Heart & Vasculature, 2016
Objective: A bicuspid aortic valve (BAV) is associated with accelerated aortic valve disease (AVD) and abnormalities in aortic elasticity. We investigated the intima-media thickness of the descending aorta (AoIMT) in patients with AVD with or without an ...

Matrix Metalloproteinase-2 Isoforms Differ within the Aortic Wall of Ascending Aortic Aneurysms Associated with Bicuspid Aortic Valve

Cardiology Research and Practice, 2020
The pathogenesis of ascending thoracic aortic aneurysm (aTAA) is thought to differ between patients with bicuspid aortic valve (BAV) and tricuspid aortic valve (TAV), and one of the causes is different hemodynamics. Influenced by hemodynamics, the tissue

Addressing Reproducibility of MXene Synthesis Using Electrochemical and Chemical Treatment of Ti3AlC2 With Tetramethylammonium Hydroxide

Small Methods, EarlyView.
MXene synthesis by etching Ti3AlC2 with tetramethylammonium hydroxide (TMAOH) is shown to be reproducible if the passivation layer on the surface of crystallites is broken by rigorous grinding of the precursor powder. Widely cited as electrochemical, etching of Ti3AlC2 in aqueous NH4Cl/TMAOH (0.2 M) electrolyte is likely to yield MXene mostly due to ...
