Changes of the light conditions in a deciduous forest

Principle

Why are there only a few different kinds of plants in a deciduous forest? Except for having trees that are all approximately of the same height, hardly any other plants grow in a deciduous forest, except for young plants of the same type of trees. This experiment shows how the ...

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 ...

Ionic permeability of the cell membrane with Cobra4

Principle

The cell membrane controls the transport of nutrients and water into the cell, and of waste products and water out of the cell. This can take place passively, e.g. on the basis of osmotic processes (differences in concentration), as well as actively.

Benefits

  • Compact, easily ...

Enzymatic activity of catalase with Cobra4

Principle

Catalase is an enzyme that - in humans - is found predominantly in the liver and erythrocytes. It decomposes hydrogen peroxide, which is a toxic byproduct of cellular respiration, into water and oxygen.

Benefits

  • Compact, easily transportable setup
  • For both demonstration ...

Magnetic Resonance Imaging (MRI) II



Principle

The aim of these experiments is to show how the spin echo technique can be used to generate 2D MR images of a slice of a well-defined thickness, orientation, and size (Localized Spin Echo 2D). These parameters determine the so-called "field of view" (FOV) of the MR image. ...
