While we are familiar with the concept of the conversion of thermal energy to mechanical work, there is a little known class of materials known as thermosalient or jumping crystals which can spectacularly turn a small temperature change...

189. Using Synchrotron Sourced Microscopy to Explore Fingermark Chemistry

The successful detection of latent fingermarks is crucial to forensic investigations, however detection methods can be hindered by variation in response or lack of robustness. Despite ongoing research into fingermark development, many remain undetected(1). A fundamental understanding of fingermark chemistry can provide explanations for the effectiveness or lack thereof for current detection...

Abstract
This presentation aims to provide a summary on the recent applications of our synchrotron macro ATR-FTIR microspectroscopy, unique to the Australian Synchrotron’s Infrared Microspectroscopy (IRM) beamline. The technique provides molecular information with sub-cellular resolution down to 1-2 μm beyond the resolution limit allowed for standard synchrotron-FTIR setups and...

Maintenance of appropriate levels of endocytic trafficking and subsequent sorting in endosomes is essential for every aspect of cellular life. The evolutionarily conserved Retromer complex (composed of VPS35-VPS26-VPS29) is a central hub responsible for this process in endosomal compartments in all eukaryotes. It is known that mutations in Retromer complex can cause late-onset Parkinson’s...

242. Full-field tomography with scattered X-rays

X-ray absorption imaging relies on transmitted photons being absorbed by the subject. As a natural consequence, X-rays are also scattered in significant quantities in all directions. This makes it potentially feasible to do tomography and obtain 3D volumetric information by capturing photons using detectors placed around the subject. Scatter tomography has previously been attempted with pencil...

222. Further insights into the effect of pH on the fluorescence and structure of green fluorescent protein (GFP)

The Enhanced Green Fluorescent Protein (EGFP) has intense and natural fluorescence, and is biocompatible with a diversity of biological systems, which makes it promising for use in the development of biosensors. However, this commercial application is limited, mainly due to the high cost and lack of knowledge about EGFP stability under stress conditions. Although studies have been done into...
