High Hardness of Conductive Micro Fastener Manufactured by Micromolding Method

Evaluation of Superficial and Dimensional Quality Features in Metallic Micro-Channels Manufactured by Micro-End-Milling

Miniaturization encourages the development of new manufacturing processes capable of fabricating features, like micro-channels, in order to use them for different applications, such as in fuel cells, heat exchangers, microfluidic devices and micro-electromechanical systems (MEMS). Many studies have been conducted on heat and fluid transfer in micro-channels, and they appeared significantly devi...

Verification of BOUT + + by the Method of Manufactured Solutions

The micro-hardness of enamel and dentin.

THE hardness of enamel and dentin has been determined by a variety of methods including abrasion," 2 pendulum,' scratch,4-7 and indentation" teehnics. Since the hardness of enamel and dentin has been shown to have considerable local variations, the methods using a microscratch or microindentation have been preferred. One of the more common types is the Knoop diamond indenter14 which has been us...

Large-Area Patterning by Vacuum-Assisted Micromolding

Mater. 1999, 11, No. 11 layers we achieved were very compact films, i.e. the grains were densely arranged with a large number of inter-grain contacts. Moreover, the electrical measurements showed that Nb addition only had a negligible influence on the intergrain barrier. For these two reasons, magnific...
