On the other hand, a fungusmediated synthesis technique has recently shown potential to synthesize perovskites such as BaTiO3 with sizes as small as 5 nm. Here we report, for the first time, the use of fungal biomass, at room temperature, to break down chemically synthesized BiMnO3 nanoplates ( size similar to 150 - 200 nm) into very small particles (, 10 nm) while maintaining their crystalline structure and the phase purity. This novel technique that we have named as `` bio- milling'' holds immense potential for synergically utilizing both chemical and biological synthesis techniques to synthesize complex oxide nanoparticles with particle sizes less than 10 nm with the proper crystalline phase.</p>1 aMazumder, Baishakhi1 aUddin, Imran1 aKhan, Shadab1 aRavi, Venkat1 aSelvraj, Kaliaperumal1 aPoddar, Pankaj1 aAhmad, Absar  uhttps://library.ncl.res.in/content/bio-milling-technique-size-reduction-chemically-synthesized-bimno3-nanoplates-001189nas a2200229   4500008004100000022001400041245010500055210006900160260007700229300001000306490000700316520034700323100001700670700002500687700002000712700001700732700001900749700001900768700001700787700002900804856012600833       2007                        eng d  a0935-964800aFungus-based synthesis of chemically difficult-to-synthesize multifunctional nanoparticles of CuAlO20 aFungusbased synthesis of chemically difficulttosynthesize multif  aPO BOX 10 11 61, D-69451 WEINHEIM, GERMANYbWILEY-V C H VERLAG GMBHcNOV  a3295+0 v193 a<p>Fungal nanosynthesis of ternary CuAlO2 phase is achieved at 50 degrees C.

This method is very advantageous because it circumvents the use of SrCO3 in the case of conventional ceramics as well in the coprecipitation methods, thereby lowering the formation of the product phase. Commercially purchased strontium hydroxide is mixed thoroughly with freshly precipitated bismuth and niobium hydroxides in a stoichiometric ratio and heated at different temperatures ranging from 100 degrees C to 750 degrees C for 12 h. The sequence of the reaction and evolution of the product phase was monitored by X-ray diffraction (XRD) studies by recording the XRD for samples calcined at different temperatures. The incipient SBN phase begins to form at temperatures as low as 400 degrees C, and phase formation was complete only at 650 degrees C as revealed by the XRD observations. The differential thermal/thermogravimetric analyses) also corroborate this result. The morphology and average particle size of these powders were investigated by transmission electron microscopy studies.</p>1 aGupta, Upendra, Nath1 aRao, Koteswara1 aPradhan, Sivaram1 aJha, Ratnesh, Kumar1 aMuthurajan, Harries1 aRavi, Venkat  uhttps://library.ncl.res.in/content/novel-synthesis-srbi2nb2o9-powders-hydroxide-precursors-0
