Journal ArticleDOI
Cation distribution in nanosized Ni-Zn ferrites
TL;DR: In this article, a strong correlation between the particle size and the zinc concentration has been identified, and Mossbauer studies on these systems show that the cation distribution not only depends on particle size but also on the preparation route.
Journal ArticleDOI
Immunogenicity of bivalent types 1 and 3 oral poliovirus vaccine: a randomised, double-blind, controlled trial
Roland W. Sutter,T. Jacob John,Hemant Jain,Sharad Agarkhedkar,Padmasani Venkat Ramanan,Harish Verma,Jagadish M. Deshpande,Ajit P Singh,Meghana Sreevatsava,Pradeep Malankar,Anthony H. Burton,Arani Chatterjee,Hamid Jafari,R. Bruce Aylward +13 more
TL;DR: A randomised, double-blind, controlled trial to assess the immunogenicity of a novel bivalent types 1 and 3 oral poliovirus vaccine and the superiority of monovalent type 2 OPV over trivalent OPV, and the non-inferiority of bivalent vaccine compared with mopV1 and mOPV3.
Journal ArticleDOI
Effect of iron doping concentration on magnetic properties of ZnO nanoparticles
TL;DR: In this paper, the magnetic behavior of the nanoparticles of ZnO with varying Fe doping concentration was investigated using a vibrating sample magnetometer (VSM), initially these nanoparticles showed strong ferromagnetic behavior, however at higher doping percentage of Fe, the ferromagnetism was suppressed and paramagnetic nature was observed.
Journal ArticleDOI
Characteristic length scales of nanosize zinc ferrite
TL;DR: In this article, it was shown that there are at least two characteristic particle size length scales for nanosize ZnFe2O4 particles prepared by the nitrate route, which are related to inversion of the cation distribution, agglomeration of particles and annihilation at the surface and in the interior.
Journal ArticleDOI

TL;DR: Controversy over vaccine choice for polio eradication can be reconciled by effective combined use of IPV and Sabin together, and IPV in OPV-vaccinated individuals boosts intestinal mucosal immunity.
