Transmission electron microscope (TEM) are capable of imaging at a significantly high resolution 0.5 Å [1].  It has profound impact on varieties of field, e.g. nanotechnology, biological and material research etc. However, understanding the dynamic properties of the samples are significant. Therefore, a microchip-based ‘electrochemical laboratory’ inside a TEM holder has been built. Remarkable research results have been demonstrated and discussed, for instance, nucleation process,[2] crystal growth,[3] intrinsic electrochemistry reactions in a micro/nano battery[4].

In this project, we will focus on designing and fabricating TEM holders with different capabilities for various applications, for example, liquid flow, open cell structure with multiple electrical contacts, heating/magnetic/optical elements could also be integrated to different systems. The fabricated TEM holders will be tested and approved by CEN department for further research projects.

Following figure illustrates the TEM holders with different components

Aims:

Based on an existing holder design, you will design and fabricate TEM holders – this involves 3D design, micromilling, mechanical workshop processing, and running tests of the assembled system.

Once approved by CEN we will use it for further research.

Prerequisite:

Interested in working in mechanical workshop

Familiar with AutoCAD, Solidworks
