Reconfigurable Ferroelectric‐Like Two‐Dimensional Electron Gas at Room Temperature

Advanced Materials, EarlyView.
We demonstrate the realization of a novel ferroelectric‐like two‐dimensional electron gas (2DEG) based on the epitaxial interface between SrO‐terminate SrTiO3 and ferroeletric KNb0.5Na0.5O3${\rm KNb}_{0.5}{\rm Na}_{0.5}{\rm O}_3$ thin films. We show nonvolatile control of the transport properties enabling spatially reconfigurable devices in which ...

1‐D Collocated Dual‐Gradient Sensory Fibers for Comprehensive Sensing and Decoding of Complex Human Motion and Physiology

Advanced Materials, EarlyView.
Coupled materials design enables a monolithic fiber that integrates complementary sensing regimes into a single wearable strand. By preserving informative signal features across subtle physiological deformation, large body motion, and mixed mechanical inputs, the dual‐gradient architecture generates synchronized, less redundant outputs that improve ...

The Effect of the Rotor Static Eccentricity on the Electro-Mechanical Coupled Characteristics of the Motorized Spindle

MATEC Web of Conferences, 2016
High-speed motorized spindle is a multi-variable, non-linear and strong coupling system. The rotor static eccentricity is inevitable because of machining or assembling error.

Establishing Atomic Coherence in Twisted Oxide Membranes Containing Volatile Elements

Advanced Materials, EarlyView.
Twisted oxide membranes containing volatile elements often suffer from amorphous interfacial dead layers that suppress coupling. An oxygen‐annealing strategy establishes atomically coherent and chemically bonded interfaces in twisted NaNbO3 membranes, enabling coherent oxide moiré architectures in volatile‐element‐containing systems.

Atrial electromechanical function [PDF]

Europace, 2011
longitudinal with the mitral annulus moving back towards the rear of the atrium after the P-wave and during the PR interval and returning to its resting position at the time of the first heart sound, marking end-diastole. It is worth mentioning that not only does this pattern of function mirror that of the left ventricle, although in the opposite ...
