Auger electrons are emitted after nuclear decay and are used for medical purposes. The number of Auger electrons generated per nuclear decay is not known accurately, a fact that  hinders medical applications.  This project aims to obtain a experimental estimate of the number of Auger electrons emitted per nuclear decay.

 

This project aims to investigate how the mechnical properties of plant cells change with 'poking' from an external source. In nature the poking is by a pathogen. We mimic this effect with a diamond tip.

There is an imminent need to reduce our dependence on carbon-based fuels in order to minimize the
