Electrospray deposition (ESD) applies a high voltage to liquids flowing through narrow capillaries produce monodisperse generations of droplets down hundreds nanometers in diameter, each carrying small amount the delivered solute. This method has been combined with insulated stencil masks for fabricating micropatterns by spraying solutions containing nanoparticles, polymers, or biomaterials. To optimize fabrication process micro-coatings, self-limiting electrospray (SLED) recently developed....

ABSTRACT Poly(glycerol sebacate) (PGS) is a thermoset elastomer widely studied for biomedical applications due to its outstanding mechanical properties and biocompatibility. The standard preparation method PGS involves thermal crosslinking of prepolymer. To expand the potential this material, various strategies have been explored develop derivatives with double bonds, making them suitable mild radical under UV radiation. Typically, reactive bonds are introduced through acrylation or...

Focused laser spike (FLaSk) excitation has been demonstrated as a reliable technique for the patterning of micro-to-nanoscale features locally by thermocapillary shear thin films. Recent work on polymer films revealed that overlapping scans can leverage coupled thermal and fluid effects to create subwavelength patterns. Compared polymeric films, metallic possess both lower melt viscosity higher surface tension. Here, we investigate in dewetting ∼15 nm gold borosilicate quartz glass...

Dynamic spatial light modulators (SLMs) are capable of precisely modulating a beam by tuning the phase or intensity an array pixels in parallel. They can be utilized applications ranging from image projection to front aberration and microscopic particle manipulation with optical tweezers. However, conventional dynamic SLMs typically incompatible high-power sources, as they contain easily damaged optically absorbing components. To address this, we present SLM that utilizes viscous film local...

Macropore-Infused Nanocomposite Emulsion Thermosets In article number 2200145, Molla Hasan, Jonathan Singer, and colleagues describe the formulation processing of macropore-infused nanocomposite emulsion thermosets (MINETs) to create porous materials with tunable surface behavior pore size. It is shown that MINETs can be applied dense arrays ionic liquid emitters for space propulsion applications. The insets show experimental data fluorescent imaging inside an emitter tip a 3D CT scan...

Abstract Melting gels are a class of hybrid organic-inorganic, silica-based sol-gels which solid below their glass transition temperatures, near room temperature, but show thermoplastic behavior when heated. While this phase change can be repeated multiple times, heating the gel past its consolidation typically above 130 °C, initiates an irreversible reaction that produces highly crosslinked glassy organic/inorganic materials via hydrolysis and polycondensation. This ability makes melting...
