    “…In this paper, a novel approach is developed for the prediction of PuO(2) SSA via the synthetic route of Pu(IV) oxalate precipitation followed by calcination. The proposed model utilizes multivariate regression methodology and leave one out formalism to link Savannah River Site (SRS) precipitation and calcination production data to the SSA of the final product. …”

    “…To overcome these shortcomings, we have prepared hierarchically porous nanostructured TiO(2) macrobeads via an exotemplating or nanocasting strategy by infiltrating the TiO(2) sol into the emulsion-templated porous polyacrylamide scaffold followed by its gelation, drying and calcination. The nanoscale TiO(2) building units tailor the shape of the porous polymeric network after calcination thereby retaining the macroscale morphology of polymer beads after template removal. …”

    “…Herein, nickel phosphides with different crystalline states were prepared through a facile calcination treatment. It was found that the calcination treatment had important effects on the phase compositions, morphologies, and crystallinity of nickel phosphides, which are closely related to their HER activity. …”

Bhasma refers to calcinated metals and minerals. During this study the Bhasma of Musa paradisiaca Linn, is prepared and evaluated for its antiulcer effect in albino wistar rats which could not be attempted by researchers earlier.…”
