| 520 | _ | _ | |a In this combined talk, first a comprehensive library of nanopatterns derived from a single block copolymer (BCP) exhibit wide range of structures from simple spheres to more intricate forms, including split micelles, flower-like clusters, toroids, disordered arrays, and other unique morphologies [1]. Using polystyrene-b-poly(2-vinylpyridine) (PS-b-P2VP) surface micelles deposited on SiOx surfaces, a distinctive transformation in morphology is triggered by direct immersion in various solvents. By varying the solvent type, BCP molecular weight, substrate interactions, and temperature, the thermodynamic and kinetic parameters are also affected by these driving morphological transitions. Furthermore, the work highlights the practical utility of BCP nanopatterns as templates for fabricating metal nanostructures via direct solvent immersion. This method provides a versatile and efficient strategy for producing diverse nanostructures, with potential applications in the fields of nanolithography, catalysis, electronics, membranes, plasmonics, and photonics. Secondly, the protein crystallization (kinetics) and liquid−liquid phase separation (LLPS) are to be presented, showing the effective protein (lysozyme)-salt (NaSCN) binding in the phase diagram, with distinct crystal morphologies, by single- and multi-arm crystals, flower-like crystal structures, whiskers, and sea-urchin crystals [2]. Crystal morphologies exhibit significant variations in changes in protein and salt concentrations. Moreover, the adsorption of SCN− ions to the surface of lysozyme is effectively enhanced by applying the weak AC electric field in protein crystallization processes.Reference:[1] Seokyoung Bae, Dong Hyup Kim*, and So Youn Kim*, Small, 20, 2311939 (2024)[2] D.
