Cr³⁺ Doping Effects on Structural, Optical, and Morphological Characteristics of BaTiO₃ Nanoparticles and Their Bioactive Behavior

Crystals
This study investigates the effects of chromium (Cr3+) doping on BaTiO3 nanoparticles synthesized via the sol–gel route. X-ray diffraction confirms a Cr-induced cubic-to-tetragonal phase transition, with lattice parameters and crystallite size varying ...

Reconfigurable Ferroelectric‐Like Two‐Dimensional Electron Gas at Room Temperature

Advanced Materials, Volume 38, Issue 52, 16 September 2026.
We demonstrate the realization of a novel ferroelectric‐like two‐dimensional electron gas (2DEG) based on the epitaxial interface between SrO‐terminate SrTiO3 and ferroeletric KNb0.5Na0.5O3${\rm KNb}_{0.5}{\rm Na}_{0.5}{\rm O}_3$ thin films. We show nonvolatile control of the transport properties enabling spatially reconfigurable devices in which ...

Design of low cost gas sensor based on SrTiO 3 and BaTiO 3 films [PDF]

, 2010
We have prepared SrTiO 3/BaTiO 3 multilayer film on alumina substrates by a sol-gel technique and investigated their response for sensing ethanol vapor. The surface morphology of the films were characterized by atomic force microscope (AFM) showing that ...

Shining Light on Quantum Materials: Interplay of Symmetry, Quantum Geometry, and Nonlinear Photocurrents

Advanced Quantum Technologies, Volume 9, Issue 9, September 2026.
Nonlinear photocurrents provide broadband spectroscopic access to quantum materials from terahertz to optical frequencies. Their sensitivity to spin, orbital, chiral, topological, and quantum‐geometric properties enables insights across ferroelectrics, magnetic and two‐dimensional materials, moiré heterostructures, topological flat bands, and light ...

Exploring the Use and Impact of Composite Materials in Robotics: A Systematic Review

Journal of Field Robotics, Volume 43, Issue 6, Page 4037-4060, September 2026.
ABSTRACT Lightweight and high‐strength materials are important in robotics, as structural design impacts efficiency, payload capacity, and energy consumption. Composite materials, with their superior stiffness‐to‐weight ratios and multifunctional properties, offer clear advantages over conventional metals and polymers.

One-Step Electrical Insulating Oil Regeneration on Electret PVDF/BaTiO(3) Composite Nanofibers

, 2022
Insulating oil is a pivotal component of power transformers, but it suffers from aging byproducts during service operation. The aging byproducts from the degradation of oil insulation tend to induce insulation failure, which poses a significant threat to

Spatially Resolved Strain Mapping In Flexible Oxide Membranes

Small, Volume 22, Issue 53, 21 September 2026.
High‐resolution synchrotron x‐ray diffraction reveals how strain transfers and distributes within crystalline oriented oxide membranes (10–100 nm thick) on flexible substrates that are subjected to stretching and bending. The study uncovers local strain heterogeneities that deviate from macroscopic averages, providing a crucial framework when ...
