Characterisation

Pioneering analytical technologies

Understanding the composition and structure of a material is essential for the study of its properties and defining its us. In the Soft Matter Materials Laboratory, advanced modes to obtain information on the chemical structure of a sample as a function of its molar mass are being developed. Complex systems such as highly charged poly(ionic liquids) or Single Chain Nanoparticles (SNCPs) are precisely analysed via Size-Exclusion Chromatography hyphenated to Electrospray Ionization Mass Spectrometry (SEC ESI−MS). Pioneering SEC ESI-MS analytical technique has allowed our team to push the boundaries of analytical science to better understand how synthetic macromolecules form.

Employing SEC ESI-MS techniques allows for the generation of accurate maps of the polymer chain distributions with respect to composition and end group fidelity. Key areas of interest in our team include the development of protocols that allow the efficient ionization of variable polymer structures ranging from polar (such as polyacrylates) to non-polar (such as polystyrenes), the determination of end group chemistries via ion trapping experiments as well as the increase of both sensitivity and resolution of synthetic polymer MS.

Join us in a workshop organized by @NatureComms and @Materials_MRS on Advances in Materials and Manufacturing https://www.mrs.org/workshop-on-advances-in-materials-and-manufacturing where Christopher explores 'Wavelength Orthogonal, Synergistic and Antagonistic Photochemical Materials Design' @QUT @QUTmaterials @Cluster3DMM2O

We turned our attention once more to dynamic photochemistry with hydrogels, this time exploring wavelength orthogonal stiffening with visible light, just out in @angew_chem https://onlinelibrary.wiley.com/doi/abs/10.1002/anie.202113076 Brilliant work by @VinhXTruong and Julian @QUTmaterials @QUT @KITKarlsruhe

Australia's reputation on the international stage is once more at risk. No funding agency in a well-functioning democracy allows for ministerial interference on the expert selection of grant outcomes for political gain, personal belief or voter pleasing.
