83. New Packings and Properties for Supramolecular Nanoballs through Solvent and Counterion Variation

Oral

We have synthesised large (2.7 nm) spherical metallosupramolecules (‘nanoballs’) with interesting properties [1-3]. Metal ions can be varied with retention of overall structure and crystal packing. The molecular packing creates cavities within the solid state, and the crystals readily absorb solvents such as methanol, acetonitrile or acetone (which also changes the magnetic properties), and...

23. <i>In Situ</i> PXRD Studies of the Solvothermal Syntheses of WO₃-Ethylenediamine Hybrid Nanowires and Bi₂Se_xTe_3-x Nanoplatelets

Solvothermal syntheses are very versatile for fabricating nanostructured materials. While the majority of studies focus on materials syntheses, little attention has been paid to understanding the synthesis mechanisms, which are of vital importance to the rational design of synthesis for preparing optimized materials. In this context, in situ powder X-ray diffraction (PXRD) is ideal to...

92. Synchrotron Powder Diffraction Study of Cement Pastes

Advanced Materials

Oral

The degree of hydration of cement pastes is critical for determining properties such as the durability of concrete. As part of an integrated study on the prediction of chloride ingress in reinforced concrete, synchrotron X-ray powder diffraction was used to estimate the degree of hydration of cement pastes. While for the past 20 years the composition of Portland cement has been determined by...

118. IR spectroscopy of ferrocene and deuterated ferrocene: Experiment and theory

Prof. Feng Wang (Swinburne University of Technology)

Advanced Materials

Oral

The contemporary organometallic chemistry stems from the discovery of ferrocene Fe(C5H5)2, i.e., di-cyclopentadienyle iron (FeCp2 or Fc) half a century ago. Since its discovery, the heated debate whether the eclipsed or the staggered is the most stable structure of Fc continues. The fact that electronic structures and many properties of the Fc conformers are strikingly similar has been a key...
