Summary: Colloidal lithography offers a rapid and low-cost approach to construct 2D periodic surface nanostructures, while a new technique using ultrasonic spray has been proposed for fabricating self-assembly monolayers of polystyrene spheres at the air/water interface. This technique is efficient for both single-sized and binary polystyrene spheres, overcoming the current challenges of preparing large-area self-assembly monolayers. This innovative method has been successfully applied to create a sensitive SERS substrate for selective detection of explosive compounds.

Summary: Plasma-assisted microcontact printing (PA-mu CP) is a novel lithography method that utilizes plasma-deposited fluorocarbon as ink material to transfer patterns from a stamp to substrates via thermal evaporation. The geometry of the patterns can be modified by adjusting stamp designs and contact time, and the transferred fluorocarbon patterns can be used as etch masks for creating microstructures in substrate materials.

Summary: In this study, the molecular self-assembly of biphenyl-3,3',5,5'- tetracarboxylic acid (BPTC) at the octanoic acid/graphite interface was investigated using scanning tunneling microscopy (STM). It was found that BPTC molecules formed stable bilayers and monolayers under high and low sample concentrations, respectively. The stability of the bilayers was attributed to molecular pi-stacking, while the monolayers relied on solvent co-adsorption. Mixing BPTC with coronene (COR) resulted in the formation of a thermodynamically stable Kagome structure, but kinetic trapping of COR in the co-crystal structure was observed when COR was subsequently deposited onto a preformed BPTC bilayer on the surface. Force field calculation was performed to compare the binding energies of different phases, which helped explain the structural stability formed through kinetic and thermodynamic pathways.

Summary: This research describes the strong coupling between a plasmonic nanoparticle lattice cavity and Soret excitons in a metal-organic framework film. By infiltrating MOF pores with solvents of different refractive index, the lower polariton mode can be spectroscopically tuned. Transient absorption spectroscopy can resolve both the lower and upper polariton modes, with an estimated Rabi splitting of about 300 meV, which is nearly twice the splitting of other plasmonic cavity-organic emitter systems. The polariton modes decay faster than the uncoupled exciton. This hybrid system highlights the advantages of open plasmonic cavities for tunable coupling, as well as the usefulness of transient absorption spectroscopy in identifying polariton modes.

Summary: This paper presents a method to generate hierarchical wrinkles in two-dimensional electronic materials, allowing for spatial control over adjacent wavelengths. A rigid fluoropolymer mold was used to pattern sacrificial polymer skin layers on various 2D materials, resulting in 2D material wrinkles with wavelengths proportional to the local skin thickness. The generation of second-generation wrinkles was also demonstrated by applying subsequent cycles of polymer skin coating, strain relief, and removal. This area-specific hierarchical wrinkling enables engineering of the local properties of 2D materials and their heterostructures.

Summary: An ultralong-range coupling was demonstrated between photonic lattices in bilayer and multilayer moire architectures, which is mediated by dark surface lattice resonances in the vertical direction. Two-dimensional plasmonic nanoparticle lattices enable twist-angle-controlled directional lasing emission, even when the lattices are spatially separated by distances exceeding three orders of magnitude of lattice periodicity. The discovery of far-field interlattice coupling opens the possibility of using the out-of-plane dimension for optical manipulation on the nanoscale and microscale.

Summary: By integrating two-dimensional lead halide perovskites with plasmonic nanoparticle arrays, we have established an open and versatile exciton-polariton platform, where excitons hybridize with surface lattice resonances in the strong coupling regime. We directly observed enhanced exciton transport and demonstrated an improvement of exciton migration by more than one order of magnitude. We proposed a polariton-mediated exciton transport model and obtained an average polariton velocity of approximately 1 x 10^6 m/s for states with a photonic fraction of about 40%.

Summary: This paper presents a nanofabrication procedure that can generate multiscale substrates with quasi-random microregions of nanoparticle arrays having different periodicities and metals. The approach combines large-area nanoparticle array fabrication with solvent-assisted wrinkle lithography to control the fill factors of the arrays. It has been demonstrated that multimetallic nanoparticle arrays can function as nanoscale cavities for lasing action at low fill factors, and can exhibit lasing responses over visible and near-infrared wavelengths when multiple arrays with different periodicities are combined.
