Illuminating the Origins of Ferroelectric‐Induced Photocurrent and Hole Lifetime Enhancement in BaTiO3 Photoanodes

Advanced Functional Materials, EarlyView.
The use of ferroelectric polarization to enhance photocatalytic and photoelectrocatalytic activity is an innovative, and increasingly studied route to improve the spatial separation of charge carriers and therefore enhance catalytic efficiency. These results demonstrate how the intrinsic properties of a ferroelectric film can extend charge carrier ...

The Dirt Deposited on the Medium-Voltage Insulators Used in the Plasma Reactor and the Cylinder-Type Electrostatic Precipitator

Applied Sciences
The plasma reactor and cylindrical-type electrostatic precipitator (PRESP), combined operation in one device, made in the metallic chimney of low-thermal power boilers (up to 50 kW) that burn wood, can be used in home applications.

Ultrasoft Iontronics: Stretchable Diodes Enabled by Ionically Conductive Bottlebrush Elastomers

Advanced Functional Materials, EarlyView.
This work introduces a solvent‐free, ultrasoft, and stretchable ionic diode based on oppositely charged bottlebrush elastomers (BBEs). The BBE diode exhibits an ultralow Young's modulus (<23 kPa), a high rectification ratio of 46, and stretchability over 400%.

Pentagonal 2D Altermagnets: Material Screening and Altermagnetic Tunneling Junction Device Application

Advanced Functional Materials, EarlyView.
From a database of 170 pentagonal 2D materials, 4 candidates exhibiting altermagnetic ordering are screened. Furthermore, the spin‐splitting and unconventional boundary states in the pentagonal 2D altermagnetic monolayer MnS2 are investigated. A MnS2‐based altermagnetic tunneling junction is designed and, through ab initio quantum transport simulations,

In situ synthesis of high dielectric constant GNPs/PBO nanocomposites with enhanced thermostability

IET Nanodielectrics, 2019
Graphite nanoparticles (GNPs) were introduced into poly(p-phenylene benzobisoxazole) (PBO) matrix to produce composites via in situ polymerisation. Films of various composites were fabricated through the solution casting method in methanesulfonic acid ...

Optical Whispering‐Gallery Mode as a Fingerprint of Magnetic Ordering in Van der Waals Layered CrSBr

Advanced Functional Materials, EarlyView.
A novel nanoscale optomagnetic sensing approach is developed using whispering‐gallery mode resonances in a self‐rolled‐up microcavity. This method enables ultra‐sensitive detection of weak magnetism by correlating resonance shifts with magnetic susceptibility.
