Self‐Poled Halide Perovskite Ruddlesden‐Popper Ferroelectric‐Photovoltaic Semiconductor Thin Films and Their Energy Harvesting Properties

Advanced Functional Materials, EarlyView.
Low‐dimensional halide perovskite thin films, (BA)2(MA)n‐1PbnBr3n+1 (n = 1, 2), exhibit both semiconducting and ferroelectric properties, enabling mechanical and light energy harvesting. Using Cr/Cr₂O₃ or PCBM as barrier layers ensures reproducible ferroelectricity.

Optical Control of Ferroelectric Imprint in BiFeO3

Advanced Functional Materials, EarlyView.
Above‐bandgap irradiation at room temperature enables on‐demand optical control of defect‐driven built‐in electric fields in BiFeO₃ thin films, fabricated via scalable, chemical spray pyrolysis. These fields, otherwise “frozen‐in,” can cause severe device degradation, including non‐switchable polarization, dead layers near interfaces, and polarization ...

Short Term Oxidation of a Ti-46Al-8Nb Alloy at 700°C in Air [PDF]

, 2010
Thermogravimetry was used to study the oxidation behaviour of a lamellar Ti46Al8Nb alloy during holding at 700°C in synthetic air. A parabolic plot of the oxidation kinetics shows three different regimes over the total duration (50 h) of the tests ...

Microstructural Control and Alloy Design of the Ti-Al-Nb-W-B Alloys [PDF]

, 2008
The TiAl alloys have been considered as promising candidates for structural-materials applications at around 8000C. The major concern for the structural use of the TiAl alloys is their low ductility and poor fracture resistance at ambient temperature ...

Harnessing Interfacial Cl− Ions for Concurrent Formate Production at Industrial Level via CO2 Reduction and Methanol Oxidation

Advanced Functional Materials, EarlyView.
The replacement of the anodic OER in CO2RR with energy‐saving methanol oxidation reaction and the creation of a favorable microenvironment through interfacial Cl− ions enable concurrent formate production at industrial‐level current densities. Abstract The efficient electrocatalytic conversion of CO2 to formate is often impeded by the high energy ...
