Scanning Electron Microscope and Atomic Force Microscope

Dr Jason Gascooke and Chris Gibson (Senior Research Fellow) from the School of Chemical and Physical Sciences showed the physics students both the scanning electron and atomic force microscopes today.

Students were shown in how both microscopes work and what each is used for, and they saw images of carbon nanotubes and very very small hairs on the leg and body of an insect.  They also learned how the x-ray signature from the SEM can be used to find the elemental composition of a sample.

John Edwards speaks to Chemistry Students

John Edwards, a professionally registered toxicologist, presented an extremely interesting talk about illegal drug laboratories and the risks for the public from the chemicals and methods use to produce them. He also discussed what was involved in community risk assessment of clandestine laboratories (in collaboration with Housing SA and the SA Police) and the assessment and remediation of properties contaminated with chemicals. Of particular interest was the impact these illegal laboratories can have on the health on people living in the house, as well as that of their neighbours, or accidentally come into contact where an illegal drug laboratory had been set up in public or private property. This is of particular relevance and concern for police and Emergency Services personnel.

Professor John Beynon speaks to Physics students

John Beynon is the Executive Dean of the Faculty of Science and Engineering and he gave a fascinating talk about research at the interface of materials and mechanical engineering, and its application to real world problems.

He  showed how research into metals at a sub-atomic level can help predict how they will behave in real world situations. He discussed how metals are made up of crystals and that these are very complex structures, full of defects. And it is these defects that dominates how the metal behaves.
He also talked about how scientists and engineers can see problems from different angles, and knowing what types of questions to ask, and which areas to focus on when running experiments is an important skill to have in research.

Joe Shapter speaks to the Chemistry students

Joe Shapter is the Head of Faculty in the School of Chemical and Physical Sciences, and he presented a special workshop to the SMAF Chemistry students this week. 

Joe has a passion for teaching and this was evident when he gave a very informative and highly engaging presentation about environmental chemistry.

He initially asked the students to list the top ten problems facing the world and then showed how these were inter-related. Joe discussed some of his research into solar cell development and carbon nanotubes and how these could be used as part of the solution to some of the major issues facing the world today. The students asked lots of very thoughtful and sophisticated questions.
