Implantable Ionic Memristors Based on Natural Polymer Heterojunctions

Advanced Functional Materials, EarlyView.
We report an implantable natural polymer‐based ionic memristor composed of hyaluronic acid, chitosan, and PDMS. The device achieved 98.94% accuracy in MNIST classification while reducing training time by 36.8% compared with a conventional artificial neural network (ANN).

A Comparison Between Two-Position Variable Compression Ratio and Continuously Variable Compression Ratio Engines Using Numerical Simulation

, 2009
Two types of variable compression ratio engine are considered: i) a continuously variable compression ratio (VCR) device that optimises engine efficiency at all loads, and ii) a VCR device that allows the engine to operate at one of two discrete ...

Conformational Switching of Proteins on Material Surfaces Enabled by Peptide‐Oriented Adsorption

Advanced Functional Materials, EarlyView.
Responsive biointerfaces could be achieved using conformationally responsive proteins; however, their interconversion can be lost upon surface adsorption. Herein, we demonstrate that the incorporation a Au binding peptide into calmodulin allows for binding control on Au wherein the protein retains conformational switching. This capability was confirmed

Disentangling Bulk and Surface Contributions to Charge and Discharge Fading in High‐Voltage LiCoO2

Advanced Functional Materials, EarlyView.
High‐voltage operation of LiCoO2 accelerates capacity fading through bulk and surface degradation. By introducing a LiTaO3 coating to selectively suppress surface degradation, bulk and surface contributions to charge and discharge fading are decoupled.

Nutrition Status May be Related to Discordance of the Resting Full‐Cycle Ratio and Fractional Flow Reserve

Catheterization and Cardiovascular Interventions
ABSTRACT Background Clinical guidelines recommend using both hyperemic (fractional flow reserve [FFR]) and non‐hyperemic (instantaneous wave‐free ratio or resting full‐cycle ratio [RFR]) methods to evaluate coronary artery stenoses in patients with coronary artery disease (CAD).
