Apurba Das,Dobbidi Pamu +1 more
TL;DR: It is expected that the understanding the electrical properties would play a deciding role in developing HAp based biocompatible electronics, bio sensing and MEMS2..
Journal ArticleDOI
Mechano-tribological properties and in vitro bioactivity of biphasic calcium phosphate coating on Ti-6Al-4V.
TL;DR: Sputtering of BCP films improves wettability, mechanical properties as well as bioactivity of Ti-6Al-4V, which can be applied for orthopedic implants and in vitro bioactivity at a particular set of sputtering parameters are investigated.
Journal ArticleDOI
