Colossal dielectric constants in transition-metal oxides [PDF]

, 2009
Many transition-metal oxides show very large ("colossal") magnitudes of the dielectric constant and thus have immense potential for applications in modern microelectronics and for the development of new capacitance-based energy-storage devices.

Grain Growth-Controlled Giant Permittivity in Soft Chemistry CaCu3Ti4O12 Ceramics [PDF]

, 2007
We report a dielectric constant of up to 5.4105 at room temperature and 1 kHz for CaCu3Ti4O12 (CCTO) ceramics, derived from multiphase powders (coprecipitation products), made by a ‘‘chimie douce’’ (coprecipitation) method, and then sintered in air ...

Trophoblast lineage specification in the mammalian preimplantation embryo

Reproductive Medicine and Biology, Volume 19, Issue 3, Page 209-221, July 2020., 2020
Early blastomere which starts differentiation toward the TE cell fate still have has plasticity and can change its fate to ICM lineages depending on their positional changes. Abstract Background The establishment of the trophectoderm (TE) and the inner cell mass (ICM) is the first cell lineage segregation that occurs in mammalian preimplantation ...

Effect of the Synthesis Route on the Microstructure and the Dielectric Behavior of CaCu3Ti4O12 Ceramics [PDF]

, 2012
CaCu3Ti4O12 (CCTO) was prepared by a conventional synthesis (CS) and through reaction sintering, in which synthesis and sintering of the material take place in one single step. The microstructure and the dielectric properties of CCTO have been studied by

Dielectric properties of colossal permittivity materials: An update [PDF]

, 2013
During the last 10 years, a lot of interests have been devoted to the so-called CDC (colossal dielectric constant) materials. The first materials exhibiting this behavior were the perovskite-based ceramics on the CCTO (CaCu3Ti4O12) composition.

Discovery of Strange Kinetics in Bulk Material: Correlated Dipoles in CaCu3Ti4O12

, 2012
Dielectric spectroscopy of CaCu3Ti4O12 was performed spanning broad ranges of temperature (10-300K) and frequency (0.5Hz-2MHz). We attribute the permittivity step-fall to the evolution of Kirkwood-Fr\"oehlich dipole-correlations; reducing the moment ...

Reliability improvement in BaTiO3‐based multilayer ceramic capacitors by incorporating alloying of nickel internal electrodes

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract The mechanism of the reliability improvement by alloying Ni internal electrodes of BaTiO3‐based multilayer ceramic capacitors (MLCCs) was studied from two perspectives: electric barrier formation at the electrode‐dielectric interface and diffusion of alloying elements into the bulk dielectric layer.
