“…Similar study on magnetic measurement has been reported by the other research groups and their magnetic parameters values are suitable for electronics materials, high frequency applications, memory devices etc. [18][19][20]. More important is that, the present study opens a window to motivate this natural bhasma for high contrast MRI (Magnetic resonance imaging) techniques.…”

Abhrakh bhasma is an Ayurvedic medicine widely used for treating several diseases such as; pernicious, sickle cell anemia, Bell's palsy, hepatic dysfunction, leukemia, sex debility, cystic fibrosis, post encephalic dysfunction and cervical dysplasia etc. An Ayurveda bhasma is a medicine, which is used since ancient time and claimed to be very useful medicine at Nano metric scale. However there is a need of scientific evidence of such Ayurvedic products using modern scientific techniques of 21 st century. The physical behavior was measured by X-ray diffractometer (XRD), fourier transform spectroscopy (FTIR), vibrating sample magnetometer (VSM), scanning electron microscopy (SEM), and photoluminescence (PL) spectrometer. Abhrakh bhasma is prepared by using mica as a base materials. X-ray diffraction and SEM analysis revealed that this bhasma is in nanocrystalline form and, can be considered as nanomedicine. Magnetic hysteresis (M~H) loop study by using the VSM reveals the super paramagnetic nature. Luminescence in bhasma was observed in visible region upon excitation of 200 nm laser source. This investigation reveals that, the Abhrakh bhasma may not only used as nanomedicine but also can be employed a materials for various other technological applications due to both magnetic as well as luminescence properties. Preliminary testing of Abhrakh bhasma nanoparticles was examined on Staphylococcus aureus and Escherichia coli bacteria.

“…The bottom-up nanotechnology approach, including soft chemical method, allows to synthesize homogeneous materials with defined morphology. Among these methods, especially sol-gel autocombustion [1][2][3][4][5][6], coprecipitation [7,8], the hydrothermal and solvothermal [9][10][11], the reverse micelles [12] and the mechanochemical [13] methods have been extensively studied in the last years. Ferrite produced by chemical methods is often characterized by unique properties suitable for new advanced application, i.e., magnetic high-density information storage or drug delivery or contrast agent in biomedicine [14][15][16][17][18].…”

Mn-Zn ferrite was prepared from the solution after acid leaching of spent batteries by co-precipitation method using ammonia oxalate, sodium carbonate and sodium hydroxide as precipitating agents. The co-precipitation process was performed at temperature of over 50°C by continuous magnetic stirring. The precipitates were pre-sintered at 850°C in air. Dilatometric study has revealed that lowest shrinkage (only 5.6%) showed a material obtained from an oxalate precipitant. After pressing and high-temperature sintering at 1325°C, it showed both insufficient density and the presence of pores, which contribute to the deterioration in the magnetic properties of the ferrites: the low magnetic permeability value and high magnetic losses. Ferrite prepared from hydroxide and carbonate precipitant showed a much higher shrinkage, sintered density and much higher magnetic permeability compared with the ferrite prepared from oxalate precursor.
