Exploring the application of ferroelectret nanogenerators in medical engineering

FlexMat, Volume 2, Issue 2, Page 204-224, July 2025.
Abstract Flexible devices derived from piezoelectric materials have gained considerable attention due to their exceptional biocompatibility. Among these, ferroelectret nanogenerators (FENG) is a novel type of flexible piezoelectric device that integrates self‐powering, actuation, and sensing capabilities.

SYNTHESIS, PROPERTIES CaCu3Ti4O12 WITH COLOSSAL VALUE OF THE DIELECTRIC PERMITTIVITY

Ukrainian Chemistry Journal, 2019
Ceramic materials CaCu3Ti4O12 were synthesized by solid-phase reactions technique. The sequence of chemical reactions during the synthesis has been determined. Phase CaCu3Ti4O12 appears at 700 °C. At 800 – 900 °C, the intermediate phases CaTiO3, CuTiO3 and Ca3Ti2O7 are formed. Calcium and copper titanates, CaTiO3 and CuTiO3 interact to form CaCu3Ti4O12.

High breakdown electric field and ultralow loss in Sb+Ho co-doped TiO2 giant dielectric ceramics induced by strongly coupled defect clusters

Journal of Materiomics
Achieving a large dielectric constant and high breakdown electric field simultaneously has been a hot and difficult topic for co-doped TiO2 ceramics. In this study, (Sb0.5Ho0.5)xTi1–xO2 (SHTOx, x = 0, 0.01, 0.02, 0.04 and 0.06) ceramics with strongly ...

Point defect structure of La-doped SrTiO3 ceramics with colossal permittivity [PDF]

Acta Materialia, 2019
Abstract Sr1-xLaxTiO3 (SLTO) ceramics with colossal permittivity were fabricated by conventional solid-state reaction method. The point defects of pure STO and SLTO ceramics were analyzed by Positron Annihilation Lifetime Spectroscopy (PALS) and Coincidence Doppler Broadening (CDB).

Materials with Colossal Dielectric Constant: Do They Exist?

, 2002
Experimental evidence is provided that colossal dielectric constants, epsilon >= 1000, sometimes reported to exist in a broad temperature range, can often be explained by Maxwell-Wagner type contributions of depletion layers at the interface between ...

Characterization of multiple binding sites on microtubule associated protein 2c recognized by dimeric and monomeric 14‐3‐3ζ

The FEBS Journal, Volume 292, Issue 8, Page 1991-2016, April 2025.
Microtubule associated protein 2c (MAP2c) interacts with the regulatory protein 14‐3‐3ζ in a phosphorylation‐dependent manner. In its unphosphorylated state, MAP2c binds 14‐3‐3ζ via its microtubule binding domain and its central region. However, upon phosphorylation by cAMP‐dependent protein kinase (PKA), 14‐3‐3ζ preferentially binds to the ...
