Zweidimensionale Polymere als modulare metallfreie Festkörperkatalysatoren für die effiziente sono‐piezo‐photokatalytische Wasserstoffperoxidherstellung

Angewandte Chemie, EarlyView.
Diese Studie demonstriert die hohe piezo‐photokatalytische Aktivität von festen molekulare Katalysatoren (Englisch: Solid Molecular Catalysts, SMCs) bei der Produktion von Wasserstoffperoxid aus Wasser und Sauerstoff. Durch den rationalen Entwurf der molekularen Motive (Diphenylpyridin oder Terpyridin) sowie der Rückgratfunktionalitäten (Methylgruppe ...

Multimodal Physical Fitness Monitoring (PFM) Framework Based on TimeMAE-PFM in Wearable Scenarios

2024 5th International Conference on Computer Engineering and Application (ICCEA)
Physical function monitoring (PFM) plays a crucial role in healthcare especially for the elderly. Traditional assessment methods such as the Short Physical Performance Battery (SPPB) have failed to capture the full dynamic characteristics of physical function. Wearable sensors such as smart wristbands offer a promising solution to this issue.

Materials Contrast in Piezoresponse Force Microscopy

, 2006
Piezoresponse Force Microscopy contrast in transversally isotropic material corresponding to the case of c+ - c- domains in tetragonal ferroelectrics is analyzed using Green's function theory by Felten et al. [J. Appl. Phys. 96, 563 (2004)]. A simplified

Two‐Dimensional Polymers as Modular Metal‐Free Solid‐State Catalysts for Efficient Sono‐Piezo‐Photocatalytic Hydrogen Peroxide Production

Angewandte Chemie International Edition, EarlyView.
This study demonstrates the high piezo‐photocatalytic activity of solid molecular catalysts (SMCs) in the production of hydrogen peroxide from water and oxygen. Through the rational design of molecular motifs (diphenylpyridine or terpyridine) and backbone functionalities (methyl group, aliphatic amine antenna, or aromatic pyrrole unit), as well as ...

Magnetron Sputtering Synthesis of La‐Doped BiFeO3 Thin Films and Enhanced Exchange Bias in CoFeB/Bi1‐xLaxFeO3 Heterostructures

Advanced Physics Research, EarlyView.
This study explores the epitaxial growth of high‐quality La‐doped BiFeO3 (BLFO) thin films at 550 °C using magnetron sputtering. The films exhibit good ferroelectric properties and low leakage current. A BLFO/CoFeB heterostructure is constructed, achieving an exchange bias field exceeding the coercive field at room temperature.
