Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry

Advanced Functional Materials, EarlyView.
In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...

Monitoring device for early warning signs of operator fatigue in open cut mines

, 2005
An investigation into technologies to detect impaired performance due to driver fatigue was undertaken. From this, a new forced-choice stimulus-reaction device was developed specifically to detect driver impairment in operators of haul trucks in open cut

Ferroelectricity in Antiferromagnetic Wurtzite Nitrides

Advanced Functional Materials, EarlyView.
We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and

Role of Intrinsic Electron Trapping in Negative Charging of Amorphous Alumina

Advanced Functional Materials, EarlyView.
Intrinsic electron trapping in amorphous Al2O3 is examined using hybrid‐DFT models spanning a wide density range. Both spontaneous and thermally activated trapping are identified, with pronounced spontaneous localization in dense, partly crystallized structures.

Development of a Low-Cost Portable Iontophoresis Device

Cureus
Hyperhidrosis, particularly of the palms and soles, is a common condition characterized by excessive and uncontrollable sweating that can significantly affect daily activities and quality of life. Among the many various treatments, the iontophoresis has emerged as a safe, simple, and non-pharmacological solution.
