Oxygen vacancies in strained SrTiO$_{3}$ thin films: formation enthalpy and manipulation [PDF]

, 2017
We report the enthalpy of oxygen vacancy formation in thin films of electron-doped SrTiO$_{3}$, under different degrees of epitaxial stress. We demonstrate that both compressive and tensile strain decrease this energy at a very similar rate, and promote ...

Pt‐Decorated Bi4Ti3O12/CeO2 Heterojunction for Highly Selective CO2 Photoreduction to Methane

ChemCatChem, Volume 18, Issue 6, 27 March 2026.
ABSTRACT Solar‐light‐driven CO2 photoreduction offers a promising route for mitigating carbon emissions while enabling sustainable fuel generation. Aurivillius‐type bismuth titanate (Bi4Ti3O12) is an attractive photocatalyst owing to its structural stability and ferro‐/piezoelectric properties; however, its application in gas‐phase CO2 conversion is ...

Charge writing at the LaAlO3/SrTiO3 surface

, 2010
Biased conducting-tip atomic force microscopy (AFM) has been shown to write and erase nanoscale metallic lines at the LaAlO3/SrTiO3 interface. Using various AFM modes, we show the mechanism of conductivity switching is the writing of surface charge ...

Bioinspired Wet‐Laid Electrospun Short Fiber Hybrid Networks for Aerosol Filtration

Advanced Functional Materials, Volume 36, Issue 4, 12 January 2026.
A facile approach for fabricating flexible and mechanically robust wet‐laid hybrid fibrous networks (WHFNs) as long‐term stable air filters is reported. The resulting WHFNs exhibit high filtration efficiency (91.91% for PM1 and 100% for PM2.5), a low pressure drop (92.6 Pa), and excellent mechanical strength (7.5 MPa), making them highly promising for ...

Thermal Shielding and Vapor Transport Enhancement in MOF‐Enabled Membranes for Membrane Distillation

Advanced Science, Volume 13, Issue 6, 30 January 2026.
A metal–organic framework‐enabled membrane (MEM) with a hierarchical porous structure is developed for thermal‐efficient membrane distillation. By embedding ZIF‐8 onto PH nanofibers, the MEM achieves low thermal conductivity and significantly enhances vapor flux and thermal efficiency.
