Multifunctional Chiral Three-Dimensional Phosphite Frameworks Showing Dielectric Anomaly and High Proton Conductivity

Frontiers in Chemistry, 2021
Chair 3D Co(II) phosphite frameworks have been prepared by the ionothermal method. It belongs to chiral space group P3221, and the whole framework can be topologically represented as a chiral 4-connected qtz net.

Ultrafast synthesis and sintering of materials in a single running experiment approach by using electric fields

Journal of Advanced Ceramics, 2019
Processing of materials in the form of ceramics normally involves several steps including calcination at a relatively low temperature for synthesis of the end-product powder and sintering at a high temperature for densification.

Development of a Moisture-in-Solid-Insulation Sensor for Power Transformers

Sensors, 2015
Moisture is an important variable that must be kept under control to guarantee a safe operation of power transformers. Because of the hydrophilic character of cellulose, water mainly remains in the solid insulation, while just a few parts per million are
