Soft chemistry synthesis of the perovskite CaCu3Ti4O12 [PDF]

open access: yes, 2007
The perovskite CaCu3Ti4O12 (CCT) has been obtained after calcination of oxalate precursors at 900–1000 °C in air. Those precursors are prepared using a soft chemistry method, the coprecipitation.

MM-PBSA and the Importance of the Dielectric Constant for Kinase Drug Design

open access: yes, 2020
Predicting the interactions between a set of small molecules and its target plays a critical role in drug discovery and development. Especially in later stages of the drug design process, when a reduced set of molecules is in focus, reliable and accurate

A Comparative Study of Physicochemical, Dielectric and Thermal Properties of Pressboard Insulation Impregnated with Natural Ester and Mineral Oil [PDF]

open access: yes, 2011
Natural ester is considered to be a substitute of mineral oil in the future. To apply natural ester in large transformers safely, natural ester impregnated solid insulation should be proved to have comparable dielectric strength and thermal stability to ...

Dielectric constant of water in the interface [PDF]

open access: yesThe Journal of Chemical Physics, 2016
We define the dielectric constant (susceptibility) that should enter the Maxwell boundary value problem when applied to microscopic dielectric interfaces polarized by external fields. The dielectric constant (susceptibility) of the interface is defined by exact linear-response equations involving correlations of statistically fluctuating interface ...

Effect of magnetic spins flipping process on the dielectric properties of α-Fe1.6Ga0.4O3 system

open access: yesAIP Advances, 2015
The α-Fe1.6Ga0.4O3 (Ga doped α-Fe2O3) sample has been stabilized in rhombohedral structure. The sample is a canted ferromagnet at 300 K and above. The spins structure starts flipping from in-plane direction to out of plane direction of the rhombohedral ...
