Direct one-pot synthesis of L10–FePtAg nanoparticles with uniform and very small particle sizes

If tetragonal FePt nanoparticles (NPs) are to be used as magnetic recording media, a means of transforming the particles into the tetragonal phase while maintaining the small particle size must be found.

Sole Product

When a fine fraction of kaolinite (less than 2 μm) is mixed with titanyl sulphate (weight ratio approx. 1:7), hydrolysed, washed, dried and heated to temperatures between 750 and 900 ° C, it transforms into metakaolin, and titania crystallizes as anatase with a small particle size (approx. 20–30 nm). In parallel experiments with plain titania (without kaolinite), rutile is the sole product phase at 850 and 900 ° C and the dominant phase in a mixture with anatase at 750 ° C. The particle sizes are much larger (approx. 400–1100 nm). It appears that kaolinite is instrumental in preserving titania in the anatase form and with a small particle size even at fairly high temperatures and hindering its transformation to rutile. However, this anatase exhibits poor photocatalytic activity.

Modern Era

Rasashastra deals with the Rasa Aushadhis, the drugs of metallic and mineral origin. Mercury is used in most of the Rasaaushadhis. The toxicity of Mineral and metallic preparations are reduced to such an extent by various procedures of Shodhana, Marana etc. that Mercury converts its inherent property of toxicity into medicinal property. Rasa Aushadhis works quickly on the body because due to their small particle size, their absorption starts from the oral mucosa itself. The action of drugs depends largely upon the Anupana i.e. the vehicle for the drug. Rasacharayas have mentioned various Rasa preparations like Bhasmas, Parpati, Pottali, Manduras, Karpooras etc. along with their doses, dose schedule and Anupana / Sahapana etc. The principles of Rasaaushadhis when correlated in modern era are found to be scientifically accurate. We may say that Rasacharyas had already mastered the science of nanotechnology, purification, action of metabolic catalysts, biotransformation and preservation of medicines. The Ayurvedic drugs can be harmful for our body when not administered in proper dosage as per mentioned in classic literatures.
