Pool-boiling heat-transfer experiments were carried out to observe the effects of hybrid wettable patterns on the heat-transfer coefficient (HTC). The parameters of investigation are the number of interlines and the pattern orientation of the modified wettable surface.

Classical multivariate pattern analysis predicts sensory stimuli a subject perceives from neural activity in the corresponding cortices (e.g. visual stimuli from activity in visual cortex). Here, we apply pattern analysis cross-modally and show that sound- and touch-implying visual stimuli can be predicted from activity in auditory and somatosensory cortices, respectively.

Aqueous two-phase systems were used to simultaneously pattern multiple populations of cells. This fast and easy method for cell patterning takes advantage of the phase separation of aqueous solutions of dextran and polyethylene glycol and the interfacial tension that exists between the two polymer solutions.
FAQs
Fidelity determines how closely the reproduced geometry matches the intended pattern, while resolution governs the smallest features that can be formed. Alignment controls how accurately the transferred pattern registers with existing structures on the substrate. Together, these factors influence dimensional control, device performance, and production reliability, especially in integrated circuits, microelectromechanical systems, and sensors.
A patterned resist layer separates regions that should respond differently during subsequent processing. After lithography defines the resist geometry, exposed and protected areas guide selective material removal or deposition on the target surface. This relationship allows the template or mask pattern to control which substrate regions develop features and helps preserve the intended layout during fabrication.
Etching transfers a pattern by selectively removing material, whereas deposition builds material in selected regions. Imprinting reproduces pattern geometry through a forming step rather than relying solely on removal or buildup. These methods provide different routes for creating structures on a substrate, so the appropriate choice depends on the required geometry, dimensions, alignment, and material-processing sequence.
A typical workflow begins with a template, mask, or resist layer that defines the desired geometry. Lithography establishes the patterned resist, after which selective etching or deposition creates different features in exposed and protected regions. Imprinting can provide another transfer route. Process control throughout these stages maintains the intended dimensions and alignment on the target surface.
Dimensional control ensures that transferred features retain the intended size and geometry rather than deviating during material removal, deposition, or imprinting. Such deviations can reduce pattern fidelity and affect how a fabricated structure functions. In engineering production, controlling dimensions also supports repeatable manufacturing and helps maintain reliability across integrated circuits, sensors, and nanostructured materials.
Engineering applications include integrated circuits, microelectromechanical systems, sensors, and nanostructured materials. In these areas, transferred geometries define functional structures whose behavior depends on accurate fabrication. The process is therefore relevant both to device manufacturing and to research on engineered surfaces and small-scale structures, where resolution, alignment, and reproducibility influence the usefulness of the final result.
