  Workshop Overview

  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
  “Click Chemistry” 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.

  Participants

  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.

  Workshop Overview

  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 materials’ 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.

  Monograph Overview

  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-“living” conditions including nitroxide-mediated polymerization (NMP), atom transfer radical polymerization (ATRP) and reversible addition–fragmentation 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.
