Microfabrication of ultra-thick SU-8 photoresist for microengines

A high quality UV-lithographic process for making high aspect ratio micro reciprocating engine parts on ultra-thick SU8 photoresist CO2 is described. The research work is part of an on-going microengine research project at the University of Birmingham. The project aims to develop a compact power plant for driving MEMS devices and replacing batteries. The novelty of engine design is that the eng...

Innovative SU-8 Lithography Techniques and Their Applications

SU-8 has been widely used in a variety of applications for creating structures in micro-scale as well as sub-micron scales for more than 15 years. One of the most common structures made of SU-8 is tall (up to millimeters) high-aspect-ratio (up to 100:1) 3D microstructure, which is far better than that made of any other photoresists. There has been a great deal of efforts in developing innovativ...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
