Breaking the loss barrier in CCTO: sol–gel tin enables high permittivity with capacitor-grade loss tangent

Results in Physics
Sn-doped CaCu3Ti4O12 (CCTO) ceramics were synthesized by a sol–gel polymerization route using tin (II) acetate and low-temperature sintering (1015–1020 °C) to overcome the long-standing trade-off between colossal permittivity and dielectric loss (tan δ).

Enhanced Dielectric Properties of In + Ta Co-Doped TiO₂ Ceramics Synthesized via a Green Egg White Route: Low-Temperature Sintering and Microstructural Insights

Sci
Giant dielectric oxides are attractive for next-generation capacitors and related applications, but their practical use is limited by high loss tangent (tanδ), strong temperature dependence of dielectric permittivity (ε′), and the need for energy ...

CD28-induced costimulation of T helper type 2 cells mediated by induction of responsiveness to interleukin 4. [PDF]

, 1993
Type 1 and type 2 cloned T helper (Th) cells are believed to require different antigen-presenting cell (APC)-derived costimuli for proliferation. In the case of Th1-cloned T cells, CD28 signaling costimulates production of autocrine interleukin 2 (IL-2).

Three-Dimensional Reconstruction Algorithm for a Reverse-Geometry Volumetric CT System With a Large-Array Scanned Source [PDF]

, 2003
We have proposed a CT system design to rapidly produce volumetric images with negligible cone beam artifacts. The investigated system uses a large array scanned source with a smaller array of fast detectors.
