Phase Engineering for Enhanced Piezoresponse in P(VDF‐TrFE) and Its Composites

Advanced Materials Interfaces, EarlyView.
As the temperature approaches the Curie point, the crystalline phase in P(VDF‐TrFE) decreases proportionally, while the amorphous phase increases. This shift leads to the formation of more interphase regions. Although spontaneous polarization from crystalline regions decreases, the interphase regions enable additional deformation, thereby enhancing the

Layer‐By‐Layer Deposition for 2D Nanoparticle Superlattices Stabilized by Schiff Base Reaction for a Recyclable SERS Application

Advanced Materials Interfaces, EarlyView.
2D gold nanoparticle superlattices (Au NPSLs) stabilized by Schiff base reaction are formed by a layer‐by‐layer deposition method. As‐synthesized 2D Au NPSLs show high structural stability in solvents of different polarity. Due to their high structural stability, the 2D Au NPSLs can be reused as surface enhanced Raman scattering substrates for 10 ...

Molecular Nanoarchitectonic Sensing Layer for Analysis of Volatile Fatty Acids in Bioreactor Headspaces Using a Nanomechanical Sensor

Advanced Materials Technologies, EarlyView.
A porous crystalline sensing layer has been developed in conjunction with a nanomechanical sensor for the sensitive detection of volatile fatty acids (VFAs) in admixture at high relative humidity. The sensitive, selective sensor based on supramolecular design improves the economic viability of anaerobic digesters toward a carbon neutral society ...

Mechanochemical difluoromethylations of ketones

Beilstein Journal of Organic Chemistry
We present a mechanochemical synthesis of difluoromethyl enol ethers. Utilizing an in situ generation of difluorocarbenes, ketones are efficiently converted to the target products under solvent-free conditions. The reactions proceed at room temperature and are complete within 90 minutes, demonstrating both efficiency and experimental simplicity.
