Important influence of Bi deficiency on the conducting property of Na sub(0.5)Bi sub(0.5) TiO sub(3) perovskite oxide

Santhoshkumar, B.; LokeswaraRao, P.; Ramanathan, K.V.; Bera, A.K.; Pahari, B. (AIP Conference Proceedings. 2115(1); 2019; ArticleID_030570.)

Recently it has been reported that low levels of Bi nonstoichiometry (only plus or minus 1 atomic percent) in the nominal starting composition of Na sub(0.5) Bi sub(0.5) TiO sub(3) (NBT) ceramics can lead to dramatic changes ...

LokeswaraRao, P.; Pahari, B.; Shivanand, M.; Shet, T.; Ramanathan, K.V. (Solid State Nuclear Magnetic Resonance. 84; 2017; 204-209.)

This paper reports results of sup(23)Na and sup(29)Si solid-state NMR investigations carried out on sodium strontium silicate ion conductor, Sr sub(0.55)Na sub(0.45)SiO sub(2.775) and presents the first experimental evidence ...
Structure and ionic conductivity of Na sub(3+x) Sc sub(2) Si sub(x) P sub(3-x) O sub(12) (x=0.0, 0.2, 0.4, 0.8) NASICON materials: A combined neutron diffraction, MAS NMR and impedance study

Santhoshkumar, B.; LokeswaraRao, P.; Ramanathan, K.V.; Bera, A.K.; Yusuf, S.M.; Hathwar, V.R.; Pahari, B. (Solid State Sciences. 111; 2021; ArticleID_106470.)

A knowledge of structural parameters that play a role in influencing ionic conduction is the key to the design of improved NASICON materials which have attracted significant attention in recent years as potential solid ...
sup(23)Na and sup(29)Si NMR investigation of Na-SrSiO sub(3) superior ion conductor

LokeswaraRao, P.; Pahari, B.; Ramanathan, K.V. (AIP Conference Proceedings. 1832; 2017; Article ID 070024.)

Present work reports the sup(23)Na, sup(29)Si NMR studies on the Sr sub(0.55) Na sub(0.45) SiO sub(2.775) along with PXRD and ionic conductivity studies. NMR results indicate that Sr sub(0.55) Na sub(0.45) SiO sub(2.775) ...
Supramolecular synthon identification in azelaic acid - Isonicotinamide cocrystal by solid-state NMR

Reddy, Y.J.; LokeswaraRao, P.; Pahari, B.; Tothadi, S.; Ramanathan, K.V. (Journal of Magnetic Resonance Open. 44845; 2022; ArticleID_100056.)

Supramolecular synthons are the smallest structural units that contain the information inherent in building large molecular assemblies. Here, we apply solid-state NMR methods for the identification of the synthon in a ...
Use of reverse cross-polarization for editing solid-state proton NMR spectra

LokeswaraRao, P.; Reddy, Y.J.; Pahari, B.; Ramanathan, K.V. (Journal of Molecular Structure. 1168; 2018; 49-55.)

We present here the use of the cross-polarization - reverse cross-polarization (CP-RCP) method for editing proton spectra by identifying protons attached exclusively to a nucleus such as carbon or nitrogen. Experiments ...
