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 ...

Boosting Fast‐Charging Performance of Ni‐Rich NCM9055 Cathodes with Nb2O5 Dual Functional Modification

Advanced Science, EarlyView.
A dual‐functional Nb2O5 modulation strategy is reported to overcome kinetic limitations in Ni‐rich cathodes. The formation of LiNbO3 phase at the grain boundary of the polycrystalline NCM9055 cathode preserves a radially aligned microstructure and establishes fast lithium‐ion pathways.

Phototriggered Morphological and Compositional Change of UGGAA Repeat RNA Foci by Photoswitchable RNA‐Binding Ligand

Angewandte Chemie, EarlyView.
We here developed a molecular tool for the optical control of UGGAA repeat RNA foci, a pathological hallmark of spinocerebellar ataxia type 31 (SCA31). The photoswitchable RNA‐binding ligand enabled reversible control of the RNA foci. UV irradiation induced the growth of the RNA foci, while subsequent visible light irradiation dissolved the structure ...

Supercritical antisolvent coprecipitation mechanisms

The Journal of Supercritical Fluids, 2018
Abstract Supercritical antisolvent precipitation (SAS) has been successfully used to produce microparticles and nanoparticles of controlled size and distribution either as a single precipitates or by coprecipitation of two or more compounds. SAS coprecipitation process has produced different particles morphologies and, differently from the single ...
