How water meets a very hydrophobic surface
Sudeshna Chattopadhyay, Ahmet Uysal, Benjamin Stripe +4
Is there a low-density region ('gap') between water and a hydrophobic surface? Previous X-ray/neutron reflectivity results have been inconsistent because the effect (if any) is sub…
Confinement Induced Polarization effects in Valence and Inner-shell Spectra of Atactic Polystyrene
Sudeshna Chattopadhyay, A. Datta, A. Giglia +2
Vacuum ultraviolet (VUV) transmission spectra show a clear polarization effect in pi electronic transition in spin coated atactic polystyrene (aPS) films of thickness below 4Rg, wh…
Nanoconfined Polystyrene: A New Phase
Sudeshna Chattopadhyay, Alokmay Datta, Avijit Das +3
Transverse layering of molecular gyration spheres in spin-coated atactic polystyrene () films, for film thickness 4 ( = unperturbed gyration radius), causes…
Tunable Self-assembly of Au-nanoparticles with Near-Perfect Monodispersity
Sudeshna Chattopadhyay, Alokmay Datta
Au nanoparticles with near perfect monodispersity in shape and size self-assemble, very slowly and at room temperature, on polystyrene films for film thickness < 4R_{g}$, R_{g} bei…
Localization of Excitons by Molecular Layer Formation in a Polymer Film
Sudeshna Chattopadhyay, Alokmay Datta
Atactic polystyrene of two different molecular weights (560900 g.mol-1 and 212400 g.mol-1) have been studied as spin-coated films of thickness varying from ~30 nm to ~250 nm, i.e.,…
