In the design of tubular bridges, engineers have found the fatigue performance of the joints to be a critical aspect that may have a significant impact on the economic viability of these structures. In looking for ways of improving this performance, the us ...
During this project, ultrasensitive cantilevers designed for nuclear magnetic resonance applications were fabricated and characterised. The cantilevers are 500, 340 or 200 μm long, 10 or 20 μm wide and 500 or 340 nm thick and integrate a thin film of cobal ...
Machining of various electrically non-conductive materials is possible with Spark Assisted Chemical Engraving (SACE). Even though this technology presents several interesting properties like simplicity, flexibility and the possibility to obtain very smooth ...
In this paper, several probabilistic models for evaluating the fatigue performance of post-weld treated tubular bridge structures are briefly described. The application of the models is then demonstrated on a full-scale example bridge. Under realistic traf ...
Two methods to fabricate artificial nanoscale mechanical devices are presented. One is based on the combination of local Ga+ doping of silicon by a focused ion beam and KOH etching. The second is based on the use of nanostencil as miniature shadow mask to ...
This thesis deals with the development of microfabrication technologies based on photoplastic structuring by lithographic and molding techniques. These technologies, combined with an original releasing method, allow for the simple fabrication of pseudo thr ...
A simple and efficient technique for the fabrication of buried microfluidic channels is presented. Microchannels made using a contribution of thick liquid and laminated photopolymers are used for the realization of smart microchips for culture, stimulation ...
In this paper, the necessity for a high pressure valve is discussed, and a design for such a valve that has been previously presented is described. This valve can be built using simple fabrication techniques available in microsystem foundries. Its fabricat ...
This paper suggests a new fabrication method for surface micromachining based on porous silicon formation followed by electropolishing. in contrast to its known use as a sacrificial layer, in this work, porous silicon will be employed as constitutive mater ...
First investigations of photoacoustic (PA) spectroscopy (PAS) of methane using an antimonide semiconductor laser are reported. The laser fabrication is made in two steps. The structure is firstly grown by molecular beam epitaxy, then a metallic distributed ...
