Basic methods in imaging of micro and nanostructures with AFM (Atomic Force Microscopy)



Principle

Approaching a sharp silicon tip mounted on a cantilever to a sample surface leads to an atomic scale interaction. The result is a bend of the cantilever which is detected by a laser. In static mode the resulting deflection is used to investigate the topography of the ...

Contrast medium experiment with a blood vessel model

Principle

When a blood vessel model is irradiated with X-rays, the blood vessels themselves are not visible at first. It is only after the injection of a contrast medium that the blood vessels become visible.

Tasks

  1. Inject a 50% potassium iodide solution into the blood ...

Steam distillation

Principle

An elegant and simple apparatus for carrying out water vapour distillations: the advantage of this arrangement is that it eliminates the need for a separate vapour generator, making it possible to operate with a single heat source (other set-ups require two). The vapour is ...

Changes in the blood flow during smoking with Cobra4

Principle

Cigarette consumption influences the diameter and therefore the circulation of the peripheral blood vessels. This experiment studies the change of the finger temperature during smoking.

Benefits

  • Simple and effective method to create hard data which shows the effect of ...

Human merging frequency and upper hearing threshold

Principle

The hearing range depends greatly on age. While tones above the upper acoustic threshold are not perceived at all, individual sounds under the lower hearing threshold are perceived as a continuous deep tone (merging).

Benefits

  • Exciting experiment for all age groups
  • Simple ...

The effect of gravity and centrifugal force on plants

Principle

The main shoot of a plant generally follows a perpendicular direction away from the centre of gravity of the earth (negative geotropism), whereas the main root grows towards the centre of gravity (positive geotropism). If however the plant is placed on a rotating horizontal disk, ...
