Summary: In this study, replicas with resolution doubling were successfully fabricated using capillary force lithography. By studying masters of various characteristic sizes and utilizing thin films with thickness ranging from 50 nm to 100 nm for DVD masters, it was found that this method breaks the one-to-one replication rule and exhibits excellent reproducibility and stability.

Summary: The aligned nanostructure of perfluorinated polymer electrolytes, achieved through capillary force lithography, enables increased proton conductivity. A hierarchical structure is realized through soft lithography, allowing control over the structures of proton-transporting channels. The line-patterned membranes show enhanced proton conductivities, as confirmed by electrochemical impedance analysis. Moreover, an increased interfacial contact area improves the power generation efficiency of the membrane-electrode assembly in proton-exchange membrane fuel cells.

Summary: Patterning functional inorganic nanomaterials is an important process for advanced manufacturing of quantum dot electronic and optoelectronic devices. This paper introduces a new approach called heat-induced patterning of inorganic nanomaterials (HIPIN), which utilizes local heating to pattern colloidal nanomaterials with thermally unstable surface ligands. HIPIN extends the scope of direct optical lithography to longer wavelengths and enables patterning of light-absorbing nanomaterials, while retaining their photoluminescence quantum yield.

Summary: The study reveals a new kind of instability in drying films of emulsions, where cracks appear between droplets forming aggregates in a regular pattern. This pattern only occurs in adhesive emulsions where droplets stick together, and the characteristic length of the pattern depends on the adhesion strength and film thickness. This instability is attributed to the gel structure and elastic properties of adhesive emulsions, with implications for obtaining homogeneous films or controlling the structure of materials.

Summary: Local oxidation lithography shows potential for patterning proteins with nanometer accuracy on conductive substrates such as silicon, allowing for copatterning of multiple types of protein complexes with retained functions. Experimental conditions are established for efficient substrate surface modification and protein immobilization. This technique could be used for fabricating bioinspired nanoscale architectures for biosensors and solar cells.

Summary: We present a simple method for creating large-area, microscale resolution patterns of functional amines on self-assembled monolayers using a photoacid-enriched elastomeric stamp. The limited diffusion of the photoactivated acid enables confined deprotection of N-Boc amino groups to narrow line widths. The experimental setup is based on a conventional HD-DVD optical pickup, making it cost-efficient and maskless.

Summary: This study investigates the evolution of expansion force during thermal runaway process of large format lithium-ion battery under overcharge, revealing that the rupture of the battery shell is the trigger of thermal runaway event. The expansion force increases dramatically with the state of charge, reaching up to 3400 N. The early abnormal expansion of the battery is caused by lithium dendrite, lithium plating, and CO produced by incomplete electrolyte oxidation.

Summary: The research shows that the concentration of bacterial solution significantly affects the shape and stability of liquid films, with low concentrations leading to drainage and rupture processes, while high concentrations result in bacteria forming a single-layer array in the center and enhancing the stability of the film. The distinct dynamics in film evaporation are caused by differences in lateral capillary force of particles at different positions on the liquid film, which is not affected by particle's active motility.
