Article 11 – Quantitative 3D Optical Birefringence in Peptide Bioelectrets

Abstract: Pharmaceutical contaminants in water represent a growing environmental concern due to their persistence and potential ecotoxicity. In this study, a hybrid Bi2WO6@WS2-PVDF-HFP (Poly(vinylidene fluoride-co-hexafluoropropylene) film was developed and evaluated as a sonophotocatalytic platform for the efficient degradation of trimethoprim (TMP) in both model and real water matrices. Comprehensive structural,

Abstract: The electromechanical properties of hafnium zirconium oxide fluorite (Hf0.5Zr0.5O2, HZO) remain largely unexplored despite its widespread use as a ferroelectric in CMOS-compatible devices. Here, we demonstrate that electrostriction-driven phase instability enables a giant pseudo-piezoelectric response in epitaxial HZO thin films. Above a critical field of 24 kilovolts per centimeter, field-induced

Abstract: The development of smart materials that can react to external stimuli and provide controlled and frequently reversible responses is facilitated by the coupling of physical effects. In this work, a photo-pyroelectric effect based on a piezoelectric polyvinylidene fluoride-trifluoroethylene (P(VDF-TrFE)) polymer composite with fullerene C60 incorporated at different concentrations (1, 3,

Abstract: Study of nanoscale hafnia-zirconia physical properties is the key topic in fundamental and applied science. However, charge transport mechanisms and magnetic properties of HfxZr1-xO2 nanoparticles are very poorly studied both theoretically and experimentally. In this work we observed a superparamagnetic-like and superparaelectric-like response of ultra-small HfxZr1-xO2-y nanoparticles prepared by the solid-state

Abstract: Ferroelectricity in Hf0.5Zr0.5O2 (HZO) originates from a polymorphic landscape where the metastable orthorhombic phase competes with monoclinic and tetragonal forms, making functional properties highly sensitive to structural instability. Recent strategies have exploited ionic-vacancy mechanisms, either through redox interactions with the environment or by employing ferroionic heterostructures, to enhance ferroelectric performance.

Abstract: The contribution of flexoelectric coupling to the long-range order parameter fluctuations in ferroics can be critically important to the ferron dispersion and related polar, pyroelectric, and electrocaloric (EC) properties. Here, we calculate analytically the dispersion relations of soft optic and acoustic flexocoupling-induced phonons and ferrons by incorporating the flexoelectric
