Prof. Greg had visited our Institute to attend Conference held during Sept 24-27, 2019. We had a discussion about the SPARC project before the Conference as well as after the Conference. We discussed the about the planning and execution of the project.
The PhD and Masters students.
He attended the International Conference (held Sept 24-27,2020) in our Institute and also joined the discussion before and during the Conference.
Research students working polymerization and polymer modification joined this discussion.
Prof. M. Ashokkumar visited in February, 2020 to deliver lectures in a short course on Sonochemistry & Sonoprocessing and to participate in the International Workshop, GSPFM 2020.
40 students in the Short-term Course and 100 delegates in the Workshop from different local colleges and University and also from our Institute.
100 delegates in the International Workshop
Professor M. Ashokkumar visited during the one day International Workshop titled SUSTAINABLE FUNCTIONAL MATERIALS & PROCESSES (SFMP-2023) at IIT Kharagpur organized by the Rubber Technology Centre under the aegis of SPARC.
Discussion was carried out about the finalization of the Manuscript and progress of the work.
Design of polymers using ultrasound assisted polymerization in aqueous system
The Workshop was organized under the SPARC program (MHRD, Govt.
of India). The objective of this workshop was to provide a platform
to the research community to discuss and exchange their ideas and
recent findings on Green & Sustainable Processes with special
reference to the Polymeric materials. The recent advances in the
Green polymerization techniques viz. Ultrasound polymerization
technique in aqueous media, different Sustainable products
developed in recent times was discussed by experts from various
fields. This symposium will also focus on the recent progress of
âClick Chemistryâ in developing new functional materials. The
symposium summarized the significance of fundamental
chemistry for the development of polymers. The event was scheduled with several plenary lectures, invited lectures, poster presentations
and penal discussion.
The participants were from Contai PK College, Vidyasagar University, Ramkrishna Vidyamandir, Belur and also from different departments and centers in our Institute. There distinguished speakers, delegates from UAE, Czech Republic, USA and also from different industries and academia of our country, like IISER-Pune, IISER-Kolkata, Vidyasagar University, IACS Kolkata, INST Mohali, Reliance Industries, CEAT Tyre etc.
The objective of this international webinar, FPMGS-2021 is to provide a platform to the research community to exchange their ideas and recent findings in functional polymers and polymeric materials like bio-mimetic materials, metallo-polymers, supramolecular material, fluorescent material, specialty elastomers. This webinar will focus on these functional materialsâ green and sustainability aspects in terms of their preparation from renewable resources, their preparation processes (like ultrasonic processes, light induced processes, use of ionic liquid as solvent) and their applications as additives or bulk material in different products.
This webinar includes one plenary lecture and ten invited lectures by distinguished scientists, faculty members and technologists from academia and industry. It also includes two oral presentations by research scholars involved in the SPARC project. One of the interesting aspects of this webinar is that the undergraduate and master students from different local colleges and universities will also participate in this international event. So far ~ 250 delegates have registered for the event.
We are grateful to all speakers and all other delegates for showing their keen interest in this international event. We are immensely thankful to MHRD, Govt. of India for their financial support under the SPARC program to organize this webinar. We also extend our wholehearted thanks to all the concerned sections in both the Institutes for their support for organizing this workshop. We thank TechnoBiz for publicity of this webinar through their YouTube channel. Last but not the least we must acknowledge in advance the active participation of all delegates of this webinar.

There distinguished speakers, delegates from IISER Kolkata, NCL-Pune, The University of Melbourne, Australia and also from different industries like Reliance Industries, Apollo Tyres etc.
Ultrasonic waves in a liquid media generate both chemical and mechanistic effects that are actively used to perform chemical reactions, polymer synthesis, nanoparticle synthesis, colloids, food processing and so on. The application of sonochemistry in polymer science has been an interesting topic of research in the recent years. Ultrasonication acts as an external stimulus to initiate free radical polymerization (FRP) by the homolysis of the solvent, thereby generating radicals. The recent utilization of high frequency ultrasound (>100 KHz) for polymer synthesis has evoked new interest in the use of sonochemistry in the field of polymer chemistry, especially in chain growth polymerization reactions including reversible-deactivation radical polymerization (RDRP) techniques and novel applications. This review presents the principles of sonochemisty and the fundamental aspects governing the cavitation process and the radical generation process. A historical overview of the development of ultrasound-assisted polymerization with a focus on chain-growth polymerizations operating under pseudo-âÂÂlivingâ conditions including nitroxide-mediated polymerization (NMP), atom transfer radical polymerization (ATRP) and reversible additionâÂÂfragmentation chain transfer (RAFT) polymerization is provided. The utilization of ultrasound in polymer applications such as hydrogels, biomedical nanostructures, drug delivery, nanocomposite synthesis is also discussed. Unlike conventional FRP, ultrasound-initiated polymerization does not involve any external toxic chemical initiators, adds temporal control to the polymerization process, offers excellent control over the molecular weight and the microstructure of the final polymers, etc. The ultrasound assisted polymerization is a novel, clean and green technology, which can be investigated further by coupling with thermo-, mechano- or photochemical stimuli or flow chemistry. It has the potential to be scaled up into an industrial process.
