Listopad 2021. Članica projektnog tima TamilSelvi Selvam održala je javno predavanje "Optical microstructures based on surface-selective growth of Ag nanoparticles on thermally poled soda-lime glass“ na Institutu Ruđer Bošković. Na predavanju je predstavila dio rezultata svog dosadašnjeg rada, koji se odnose na promjenu afiniteta poled stakla žarenog u električnom polju) u odnosu na netretirano staklo za formiranje Ag nanočestica iz tekuće otopine srebrne soli i PVP-a u acetonitrilu. Pokazano je da nanočestice na površini poled stakla sadrže više srebra nego na netretiranom, da se afinitet ne mijenja s vremenom, te da efekt ostaje prisutan i nakon pokrivanja površine tankim dielektričnim ili Cr slojem.

TamilSelvi Selvam, member of the project team had a public presentation with a title "Optical microstructures based on surface-selective growth of Ag nanoparticles on thermally poled soda-lime glass“ at Ruđer Bošković Institute. She presented part of the results from her research, related to the change of the affinity of the poled glass (glass annealed in electric field) in comparison with untreated glass for the formation of Ag nanoparticles by wet chemistry method. It was shown that nanoparticles grown on the surface of poled glass contain more silver than grown on an untreated glass. Also, it was shown that the affinity is not changing with time and the effect remains present even after coating the surface with thin dielectric or Cr layer. This effect is used for production of a microstructure.
