High-Aspect-Ratio Micro-Mixers

High-aspect-ratio microstructures (HARMS) provide significant advantages for simple diffusion-based micro-scale mixing devices. When optimized for mixing performance and pressure drop they can outperform many more complex and expensive alternatives. These micro-mixers can be mass-produced in polymer materials using replication-based, micro-manufacturing technology. For further information contact Prof. Dimitris E. Nikitopoulos

Novel Prototype Seals

Novel high-durability seals cooled by integrated micro-manufactured heat transfer features are developed in the Center for Rotating Machinery (CeRoM). The advantages are dramatic reduction in seal interface temperature, elimination of the need to flush for cooling, improved reliability and performance along with reduced emissions, and more uniform heat removal from the seal interface resulting in improved long-term flatness. For further information contact Prof. Michael M. Khonsari.

Polymer Micro-Fluidic Chips

Complex micro-fluidic chips with integrated functional elements are designed and micro-manufactured for a variety of applications including biological assays, porous media surrogates, drug screening etc.. The micro-manufacturing methods used are based on replication, which is cost-effective as it enables continuous mass production. This is achieved through the design and use of micro-embossing with mold inserts made either through micro-milling or LiGA (Lithographie Galvanoformung Abformung) micro-fabrication. For further information contact Prof. Dimitris E. Nikitopoulos or Dr. Daniel S. Park.
