The Department of Physics, J.J. College of Arts and Science (Autonomous), Pudukkottai

arranged a special lecture programme on Tuesday 27.06.2023. Dr. D. Anbuselvan, Assistant

Professor, PG and Research Department of Physics, Rajah Serfoji Government College

(Autonomous), Thanjavur – 613 005.

Dr. D. Anbuselvan gave a brief discussion on “ Nanomaterials preparation and it’s recent

developments”. Nanoparticles are minute materials and they can be characterized into various

classes dependent on their properties, shapes or sizes. The various types of nanoparticles are

metal nanoparticles, ceramic nanoparticles, and polymeric nanoparticles. Nanoparticles have

exceptional physical and compound properties because of their high surface region and nano

scale size. Their optical properties are accounted for to be reliant upon the size, which confers

various shadings because of retention in the apparent district. Their reactivity, durability and

different properties are additionally reliant upon their novel size, shape and construction, there is

appropriate possibility for different business and homegrown applications, which incorporate

catalysis, imaging, clinical applications, energy-based examination, and ecological applications.

Weighty metal nanoparticles of lead, mercury and tin are accounted to be extremely unbending

and stable that their debasement isn't effectively reachable, which can prompt numerous

ecological poison levels.

Dr. M.K. Murali, Head and Assistant Professor of Physics, presided over the meeting.

M Vinibala III B.Sc. Physics welcomed the gathering and K. Reshma Begam III B.Sc. Physics

proposed the vote of thanks.
