Porous Graded Materials Derived From Block Copolymer Self-Assembly For Water And Energy Applications
… unique approach combining BCP self-assembly and non-solvent induced phase separation (SNIPS) allows direct formation of graded porous superstructures that can be used in various applications. The graded superstructure is composed of a uniform mesoporous surface layer of ~ 100 nm thickness on top …

Bioresorbable Osmotic Pump for Long–term Contraception
… currently on the market are mostly limited to non-bioresorbable matrix-diffusion systems. These Fickian diffusion-based systems raise problems like inconstant release rates that compromise their long-term efficacy, the requirement of surgical removal, and a long pharmacokinetic tail that delays …

Potential Applications of Graphene-Based Membrane in Solution Purification Processes
… membranes have inherent limitations, such as low separation or rejection rate, fouling, limited water flux, and high energy consumption. Two-dimensional (2D) based layered materials with tunable chemical functionalities and surface charge properties have emerged for on-demand applications, …

Size and chemistry selective membranes from block polymer templates
… in biology, medicine, electronics, and separations. The ability of block polymers to self assemble into ordered states on the nanometer level makes these materials suitable for applications that mandate structural order on this scale. By tuning the chemistry of these block domains, we …

Structure Formation Mechanism of Isoporous Block copolymer Membranes
This thesis deals with the microphase separation of poly(styrene-b-vinylpyridine) block copolymers in highly concentrated solutions induced by evaporation of a binary solvent mixture of a high and low boiling solvent. During self-assembly and non-solvent induced phase separation by immersion in …
