The method is based on spraying the volatile solution containing the nano-particles onto the supporting film using a disposable and fairly simple homemade and disposable apparatus which was developed in our laboratory.
A few droplets from the volatile solution containing the nano-particles are dropped into the top needle and sprayed using the pure Ar gas flow from the horizontal needle producing a very fine slurry which lands on the thin film coated TEM grids.
Typical conditions for gas flow:
- Gas pressure – 0.5 atmospheres.
- Flow rate – 2 liters/minute.
The computer lab consists of one main computer equipped with dedicated microscopysoftware for offline analysis of data acquired on the different microscopes.
The computer is connected to the different support PCs of the microscopesthrough the local area network and can be reached by TD-MT users with the link: \\Mika-software\Users\.
