Antibacterial and cellular response of piezoelectric Na0.5K0.5NbO3modified 1393 bioactive glass

Verma, A.S.; Kumar, D.; Dubey, A.K. (Elsevier Ltd, 2020-11)

In the present study, the combined effect of addition of varying concentrations (10–30 vol%) of biocompatible piezoelectric Na0.5K0.5NbO3 (NKN) as well as electrostatic and dynamic pulsed electrical treatment on antibacterial ...
Multifunctional Response of Piezoelectric Sodium Potassium Niobate (NKN)-Toughened Hydroxyapatite-Based Biocomposites

Verma, A.S.; Sharma, A.; Kumar, A.; Mukhopadhyay, A.; Kumar, D.; Dubey, A.K. (American Chemical Society, 2020-09-17)

In this study, hydroxyapatite (HA)-sodium potassium niobate (NKN) composites with varying concentrations of NKN (10, 20, and 30 wt %) were optimally developed at 1075 °C for 2 h. Detailed microstructural analyses have been ...
Polarization induced dielectric and electrical response of electrovector hydroxyapatite and ferroelectric sodium potassium niobate ceramics

Saxena, A.; Kakimoto, K.-I.; Dubey, A.K. (Institute of Physics Publishing, 2020-09-23)

The ability of hydroxyapatite (HA) to convert readily into an electret under low polarizing fields (1 kV cm-1) makes it as an excellent substitute for electro-active prosthetic implants. In the present study, compacts of ...
