Activating a Metallization Switch for Record Hydrogen Evolution in Single‐Atom Modified Polar MOF Piezocatalysts

Advanced Materials, EarlyView.
ABSTRACT Piezocatalytic hydrogen evolution enables the conversion of mechanical energy into chemical fuels, but its efficiency is constrained by a trade‐off between piezoelectric polarization and electronic conductivity. Strong piezoelectric polarization is essential for sufficient driving force, yet highly polar materials typically suffer from poor ...

Fabrication and properties evaluation of chitosan/BaTiO3 composite membranes for the periodontitis treatment

Scientific Reports
Periodontitis gradually damages the hard and soft tissues surrounding the tooth, leading to tooth loss. In recent years, the use of biomaterials in periodontitis treatment has expanded, including gels, nanoparticles, microparticles, fibers, and membranes.

Fabrication of BaTiO3/Ag composites using uniform Ag-deposited BaTiO3 particles

Journal of the Ceramic Society of Japan, 2009
Microstructure control of BaTiO3/Ag composite was examined from the preparation stage of Ag-deposited BaTiO3 particles. Uniform BaTiO3 particles were prepared by hydrothermal treatment of a hydroxide gel. Then Ag nanoparticles were deposited uniformly on the BaTiO3 particle surface by the reduction of diamminesilver (I) ions using glucose. Dense BaTiO3/

Spin‐Orbit Torque Induced by Switchable Crystal Inversion Symmetry Breaking

Advanced Materials, EarlyView.
An exotic crystal inversion symmetry breaking in SrRuO3/BiFeO3 heterostructure is revealed, and it can be reversibly manipulated by the ferroelectric polarization of BiFeO3. This crystal inversion symmetry breaking can dramatically enhance the spin‐orbit torque efficiency in the SrRuO3 layer by more than 60%, providing an alternative to design an ...
