Interaction of High Aspect-Ratio Micro-Pillars with Wall Turbulence
… hairy structures modeled as high-aspect ratio micro-pillars (HAMuP) and wall turbulence is presented. Micro-pillars are elastic, hair-like microstructures which have been inspired by naturally occurring examples like lateral line sensors in fish and air flow sensors in bats. The objective of …

Deposition and Characterization of Ceramic Thin Films and a New Experimental Approach to Evaluate the Mechanical Integrity of Film/Substrate Interfacial Layers
… focus ion beam (FIB) scanning electron microscope (FIB SEM), and transmission electron microscope (TEM). The effective interfacial shear strength between TiN and CrN thin films and their substrates was evaluated through a substrate- tension method and a newly introduced experimental …

Density Modulated Semi-Packed Micro Gas Chromatography Columns
… as a stable and versatile stationary phase for micro separation columns. It then describes a MEMS-based separation column design utilizing density modulation of embedded micro-pillars which attempts to optimize the balance between separation efficiency and pressure drop.

Effect of ion irradiation on the rate dependence of plastic deformation of extruded Zr-2.5%Nb
… Two methods of testing were performed: in-situ micro-pillar compressions and nanoindentation testing. Ion-implantation was observed to increase material strength and hardness. However, certain implanted micro-pillars displayed early localized failure that reduced strength. This finding warrants …

Experimental Investigation of Critical Heat Flux Enhancement on Engineered Surfaces with Infrared Thermometry
… boiling heat transfer. Surfaces engineered with microscale and nanoscale features have shown great potential to enhance CHF. However, while many hypotheses have been formulated, the mechanisms leading to such enhancement are still debated. This knowledge gap arises from the lack of measurements, …

Emergent behavior of cells on microfabricated soft polymeric substrates
… consisting of soft polymeric scaffolds at the micro and macro scales. This is owing to their unique ability to generate spontaneous, synchronous contractions either autonomously or under externally applied fields. Most of the biological machine designs reported in literature use single cells or …

Self-Replenishing, Wear-Resistant and Anti-Sticking Surfaces Based on Liquid Impregnation of Microstructured Mesoporous α-AI₂O₃ [Alpha Alumina] Matrices
… efficiency may be improved by providing surface microstructuring to MPA samples. Consequently, a fabrication process of large area surface microstructuring the bulk MPA samples was developed using replication and slip casting techniques. The microstructures are first replicated into …
