Summary: In this study, a novel solvent vapor annealing soft lithography (SVA-SL) method was developed to overcome the technical difficulties in processing high molecular-mass PGNP blends. The SVA-SL method allows for easy imprint patterning and large-scale organization of PGNPs, even with highly entangled grafted chains, resulting in enhanced thermo-mechanical properties and a wider range of potential nanotech applications.

Summary: Lead-halide perovskite (LHP) nanocrystals are an interesting material platform due to their easy synthesis and compositional versatility, allowing for tunable band gap and high photoluminescence quantum yield. Patterning colloidal LHP nanocrystals with electron-beam lithography can lead to more intricate designs and improve efficiencies. Despite some reduction in luminescent properties, this research represents a step towards patterning LHP nanocrystals at the nanoscale for device fabrication.

Summary: Strategically using electron beam irradiation and solvent annealing on an ultrathin film of polystyrene-poly(methyl methacrylate) can lead to the formation of large-area hierarchical nanoscale patterns. The variation of e-beam dosage and the tone reversal behavior of the resist significantly affect the dewetted patterns, while selective removal of PMMA blocks using suitable solvent can further reduce the size of the features.

Summary: Dielectric polymers are crucial in modern electronic and electrical applications due to their easy processing, lightweight, and high breakdown strength. By combining different polymer advantages, the dielectric polymer blending method is a feasible option to address the issue of high ε(r) and breakdown strength in dielectric homopolymers. Experimental results showed the significant impact of n-type semiconductive polymer on the dielectric and energy storage properties of PPDI/PVTC blends.

Summary: This study demonstrates the use of focused electron beam-induced etching (FEBIE) as a direct-write technique for removing carbonaceous interconnecting material in high resolution dense lines. Secondary electron imaging and atomic force microscopy measurements were used to monitor the FEBIE process, confirming the successful fabrication of well-separated FEBID lines. The application of this technique for removing interconnecting material in dense lines was further validated using backscattered electron imaging.

Summary: A synthesis technique for highly homogeneous PVDF-CaFe2O4 polymer films was developed from solution. XRD, FTIR, and ESEM experiments were conducted for structural characterizations. The addition of CaFe2O4 nanoparticles led to decreased direct and indirect band gap energies, increased refractive index, and improved nonlinear refractive index, making PVDF-CaFe2O4 nanocomposites promising for optoelectronic applications.
