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

Journal of Field Robotics, EarlyView.
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.

Direct evidence for electrostriction‐enhanced piezoelectricity in poly(vinylidene fluoride‐co‐trifluoroethylene) random copolymers

Responsive Materials, EarlyView.
Direct experimental evidence for electrostriction‐enhanced piezoelectricity is obtained for a quenched‐stretched‐annealed‐poled P(VDF‐TrFE) 52/48 mol.% random copolymer using time‐resolved small‐angle X‐ray scattering and wide‐angle X‐ray diffraction. Upon stretching up to 6% strain, the crystallinity (xc) increases 10% at the expense of the contents ...

Giant Bulk Photovoltaic Effect in Crystal Orientation Restructured Quasi‐Epitaxial BaTiO3 Films on Silicon Substrates

Small, EarlyView.
ABSTRACT The bulk photovoltaic (BPV) effect in ferroelectric (FE) materials enables the direct conversion and exchange of information between the optical and electrical domains in applications such as photonic computing and photodetection. Although the above‐bandgap open‐circuit voltage in the FE BPV effect permits a much higher photovoltage in ...

First-order phase transition and unexpected rigid rotation mode in hybrid improper ferroelectric (La, Al) co-substituted Ca3Ti2O7 ceramics

Journal of Materiomics, 2019
Ca3Ti2O7 with Ruddlesden-Popper structure exhibits the largest polarization among the known hybrid improper ferroelectrics. However, the high Curie temperature impedes the thorough study of phase transition through dielectric characterization.

High‐Power Performance of Textured Piezoelectric Ceramics Through Synergistic A‐Site Donor and B‐Site Acceptor Doping

Small Methods, EarlyView.
A/B‐site co‐doping combined with templated grain growth enables synergistic defect and domain engineering in textured PIN–PMN–PT ceramics. The approach simultaneously enhances piezoelectric response and mechanical quality factor, achieving a balanced soft–hard characteristic.

Plea for Defect Chemistry: The Fundamental Role of the Chemically Excited States in Solid‐State Chemistry and Beyond

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
In solids, the point defects take the role that in water is held by H3O+, OH−, and solutes. While the chemical ground structure (crystallographic structure) plays the role of the matrix, it is the chemically excited states (dissociation, disorder) that breathe life into the matter.

Grain size effects in BaTi0.90Hf0.10O3 ceramics with phase coexistence: the influence of nanostructuring and of the internal stress on the functional properties

Journal of Materials Research and Technology
The present study is focused on describing the influence of the sintering method (fast field-assisted Spark Plasma Sintering vs. conventional sintering) on the functional properties of BaTi0.90Hf0.10O3 ceramics with polymorph superposition around room ...

Glass ceramics containing ferroelectric phases

Bulletin of Materials Science, 1986
Glass ceramics prepared by controlled crystallization of glasses produce fine dispersion of crystallites in a glassy matrix. Glasses containing a mjor portion of constituents of a ferroelectric phase produce crystallites of ferroelectric phase in glass through a suitable heat treatment.
