109. Elastic Flexibility in Molecular Crystals

Molecular crystals are generally considered to be brittle and inelastic but they can in fact display remarkable elastic flexibility. For example, acicular crystals of bis(acetylacetonato)copper(II) can be tied, reversibly, in an overhand knot.

We have investigated the dynamic crystalline supramolecular chemistry that gives rise to this elasticity. In so doing we have determined the mechanism...

59. Strategies for morphological control in organic photovoltaic devices

Dr Valerie Mitchell (University of Melbourne)

Advanced Materials

While inorganic solar cells enjoy a level of success, high manufacturing costs and bulky modules limit their broad applicability. In contrast, organic photovoltaic (OPV) devices employ flexible thin-films of organic small molecules or polymers as the photoactive layer. OPV could provide a low-cost alternative to traditional PV, and a system of solution processing coupled with roll-to-roll...

56. Element-specific contributions to the electronic structures of inorganic cesium lead halide perovskites revealed by resonant X-ray photoelectron spectroscopy

Dr Xuechen Jiao (Australian Synchrotron)

Advanced Materials

Inorganic cesium lead halide perovskites (such as CsPbIBr2) constitute an emerging class of high performance semiconducting materials, delivering promising device performances in solar cells and light emitting devices. Despite the rapid development of device optimisation, many fundamental issues remain open. One of the questions attracting huge attention is: do the constitute elements...

36. Low energy electron inelastic mean free path of Zinc from XAFS using XERT techniques at room temperature.

Prof. C.T. Chantler (School of Physics, The University of Melbourne, Australia)

Advanced Materials

Oral

The electron inelastic mean free path (IMFP) is the average distance travelled between successive inelastic collision for an electron moving with a particular energy in a given material [1]. IMFP and Electron Loss Functions (ELF) are used in electron diffraction and LEED and EELS techniques where low energy inelastic scattering is dominant in electron transport. Measurements and theoretical...

129. Oxidant or Catalyst for Oxidation? A Study of How Structure and Disorder Changes Selectivity for Direct vs. Catalytic Oxidation Mediated by Manganese (III,IV) Oxides

Advanced Materials

Oral

Structural type and disorder have become important questions in catalyst design with the most active catalysts often noted to be “disordered” or “amorphous”. To quantify the effects of disorder and structural type systematically, a test set of manganese (III,IV) oxides was developed and their reactivity as oxidants and catalysts tested against three substrates; methylene blue, hydrogen...
