Advanced Functional Materials, EarlyView.This study uncovers a new switching mechanism in HfO2 and ZrO2, where the absence of a non‐polar layer along the a‐direction induces interaction between polar layers. Consequently, the switching barriers for growth are lower than those for nucleation in this direction, leading to a size‐dependent coercive field that matches experimental observations ...

Controllable AC/DC Integration for Power Quality Improvement in Microgrids
Advances in Electrical and Computer Engineering, 2019 Renewable energy sources can be connected to utility grids by using AC and DC integration methods. The AC integration is a practical and cost-effective method thanks to its simple structure; however, its power quality protection is weak.

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

EMI modeling method of AC-AC power converters
IEICE Electronics Express, 2011 This paper presents a new model for simulation of Electromagnetic Interference (EMI) in power converters. Despite the fact that a Matrix Converter (MC) has been selected, such methodology can be applied to other converter topologies. The EMI model relies on a combination of time and frequency domain techniques in order to not only reduce the ...
