Superparamagnetism in Graphene and Amaranthus
Superparamagnetism in Graphene and Amaranthus

Abstract:
Ms.T.Theivasanthi, a woman researcher of India has innovated superparamagnetic materials from graphene and a plant Amaranthus dubius. She has already made superparamagnetic materials from some mixed plants materials of Acalypha indica, Cynodon dactylon, Terminalia chebula, Eugenia jambolina and Cassia auriculata named as Santhi Particles. Apart from the above plants, she has innovated superparamagnetic materials from the plants of Cocos nucifera and Curcuma longa. They have been named as Santhi Particles-1 and Santhi Particles-2 respectively. Now, Santhi Particles-3 has been identified from the plant Amaranthus dubius.

Graphene and Amaranthus Superparamagnets: Breakthrough nanoparticles discovery of Indian researcher

Rajapalayam, India | Posted on September 23rd, 2014

It is essential to mention here that room temperature superparamagnetic behaviour has been observed in all the above materials. VSM analysis of the nanomaterials samples have been done at SAIF, IIT Madras (India). The preliminary research result / figure confirm their superparamagnetic behavior. Further research on this issue is undergoing. Also, an attempt has been made to find magnetic behaviour of Butter beans (Phaseolus lunatus) and Jackfruit seed nanopowder (Artocarpus heterophyllus). Samples of both these materials have shown diamagnetic behaviour.

Graphene is an amazing, man-made, super strong, super light material and has better electron mobility / better electricity conductor than other metals. It conducts / accepts electrons and injects electrons into other materials. It is used as filler to boost mechanical, thermal and electrical properties of composite materials. It is also used in Supercapacitors / ultracapcitors or electrochemical double-layer capacitors (EDLCs) which could store as much energy as an electrochemical battery and charge up in a matter of seconds.

Amaranthus has highly nutritious grains and leaves which are utilized as food material. It contains large amounts of protein, essential amino acids (lysine), vitamins, dietary fiber and dietary minerals (iron, magnesium, phosphorus, copper, manganese, calcium, potassium and zinc).

The scientist Ms.Theivasanthi explains, graphene superparamagnetic material has been made from mechanical grinding of graphite which is the fastest way to make large quantities of such material. She also states, superparamagnetism is the magnetic state of a material between highly ordered parallel spins (ferromagnetism) and randomly ordered spins (paramagnetism). It improves the accuracy of spintronic sensors because a small sensed field is sufficient to order the spins in a superparamagnetic material. Such improved and accurate sensors are useful in number of applications including biosensor.

Previous reports say that graphene is biologically inert material. Hence, the superparamagnetic materials prepared from plants materials as well as graphene will be bio-compatible in nature and will be very useful in various fields, industrial applications and biomedical applications particularly in biology / biotechnology fields.
