Centrifuge-aided Micromolding and Sintering of Micron- and Submicron-sized Ceramic Features
… in realizing the miniaturization of devices. Micromolding and sintering play critical roles in fabricating micron- and submicron-sized ceramic features using nanoparticles. Developed from soft lithography, replica molding has been proven a good method to prepare micron- and submicron-sized …

Ceramic microforming process
… micron scale features has been developed. This micromolding process takes advantage of clean room compatible techniques to create silicon etchings, which are used to create a silicone transfer mold. The silicone molds are used to make numerous sacrificial mold into which ceramic slurry is cast. …

Polyelectrolyte multilayers (PEM) in micro / nanofluidics for novel BioMEMS platforms
… of bacteria is presented, based on the use of micromolding in capillaries (MIMIC) of poly(ethylene glycol)-poly(lactide) diblock copolymer (PEG-PLA) onto polyelectrolyte multilayers. Two different implementations showed excellent selective antibiofouling results for micropatterning of bacteria.

Development of electrode manipulated close-packed microplasma jet arrays in a transparent polymer
… transparent polymer in multiple dimensions. A micromolding-based assembly process enables microplasma jets to be generated in cylindrical microchannels with diameters ≤350 μm, and jet lengths up to ~4 mm when the He backing pressure is ~840 Torr. Driven by a 20 kHz sinusoidal ac voltage …

Development of a hybrid process for manufacturing surgical-grade knife blade cutting edges from bulk metallic glass
… process integrating thermally-assisted micromolding and micro-drawing has been developed for producing BMG surgical-grade knife blade cutting edges with edge radii <25 nm. A hybrid process testbed was designed and used to successfully run tests over a range of the key process variables. …

Investigating wetting characteristics on microstructured surfaces for superhydrophobicity and metal microcasting
… integrated microstructures. Unlike conventional micromolding tools, the aluminum mold was large and had complex curved surfaces. The aluminum was cast into curved microstructured ceramic molds which were themselves cast from curved microstructured rubber. Many structures were successfully cast …

Design and Optimization of Moldable Microstructures for Structural Color Generation
The use of structural color, common in nature, has been slow to catch on in manufacturing. Recent work has identified many of the structural features that lead to the advanced structural colors seen in nature, and some have even been successfully recreated. However most of these features are …
