Just, by development of novel protocol for ultrasonicator assisted synthesis, or any kind of research work. Use ultra sonic wave as source of energy. DO some literature survey related to your research.
Use of ultra sonic wave as source of energy is a green method of synthesis of organic compds. However the reactions are slow , hence you need long time for the reaction.Using the higher temperature the yields can be increased.
Using ultrasound technique is one of the Green Chemistry in organic synthesis.It is a very active and safe source of energy, forming cavitation, in this period of time it reaches to the energy on the SUN. The reactions NOT need heating (reflex).
It increase the yield ( and purity) and decrease the reaction time. My group is working on this technique since 1986, We published many articles in this field. You can get it from my Google Scholar and Research Gate.
Please, don't hesitate contact me for more informations.
