When VIP visitors come to the Australian Synchrotron (Commonwealth Ministers & their minders, Directors of national and international laboratories & research institutes; VCs & DVCRs; my Mother-in-Law;…) we like to play a little game to try and impress them and to demonstrate the impact of our efforts. It goes a little like this:

Semiconducting nanoparticles (quantum dots) show a wide range of potential applications due to their unique size-dependent physical and chemical properties. A major issue today concerns the make of such particles with a sufficient control of the particle size, shape and polydispersity, which calls for a good understanding of the formation mechanisms involved. We have developed a free liquid...

Conducting polymers are a key component of modern technologies: they are used in batteries and in displays, and they have a promising future in solar conversion and emerging technologies like flexible electronics. The polymer formed from 3,4-ethylenedioxythiophene, known as poly-3,4-ethylenedioxythiophene or PEDOT, is used in a variety of applications, primarily because of its low bandgap,...

The challenge posed by charge accumulation at the interfaces of low dimensional electronic devices has resulted in a wide range of novel architectures as well as potential applications in organic electronics such as organic photovoltaics. These devices include, among others, organic light-emitting diodes and organic thin-film transistors. Within such devices, the use of lithium fluoride (LiF)...

Semiconducting polymers are of interest for a range of applications including organic light-emitting diodes (OLEDs), polymer solar cells and flexible electronics. When used as the active layer in solution-processed organic field-effect transistors (OFETs) one usually finds that charge carrier mobility increases with increasing molecular weight, due to the ability of longer chains to bridge...

Interfaces are the key to understand manifold chemical and physical processes, for instance catalytic reactions as well as nanoparticle nucleation and growth. Nanoparticle surfaces have a strong tendency to restructure to strained atomic arrangements in order to stabilize themselves at their finite size [1,2]. But also restructuring of the solvent molecules takes place. The presence of...

Magnesium-based thermoelectric materials (Mg$_2$X, X = Si, Sn, Ge) have received considerable attention due to their availability, low toxicity and reasonably good thermoelectric performance. However, the synthesis of these materials with high purity is challenging due to the volatility and high vapor pressure of magnesium. In the current study, single phase *n*-type Mg$_2$Ge has been...

By using X-Ray Photoelectron Spectroscopy and Scanning Tunneling Microscopy we have been able to follow the time evolution of graphene layers obtained by annealing 3C SiC(111)/Si(111) crystals at different temperatures. Analysis of the atomic resolution images and of the Carbon signal provides a clear picture of the graphene formation. We have been able to visualise by STM the first steps of...

Technology development and device-design based upon graphene materials require reliable techniques for mass production that are time-robust and reproducible. CVD-synthesis is expected to be the prime candidate for such up-scaling. Copper is a preferred substrate for CVD. Details of the graphene-copper substrate interactions in regard to mechanical stability and electronic band structure are...

With excellent characteristics such as high mechanical properties and electrical conductivity, graphene nanoplatelets (GNPs) can be used for reinforcing polymers and developing novel materials. In the current study, different concentrations of GNPs (0-15 wt%) were embedded into poly lactide and poly (butylene adipate-co-terephthalate) which are among the leading biodegradable polymers....

Under specific conditions incoming light can excite a wavelike oscillatory resonance in the free electrons of a conducting material. When this oscillation propagates along a surface it is usually termed a surface plasmon polariton; when confined to a discrete nanoparticle as a standing wave it is more correctly termed a localised surface plasmon resonance (LSPR). There is currently...

A hydrophilic thin-film-composite (TFC) nanofiltration (NF) membrane has been developed through the interfacial polymerization (IP) of amino-functional polyethylene glycol (PEG) and trimesoyl chloride. The selective layer is formed on a polyethersulfone (PES) support that is characterized using FTIR, XPS and SEM, and is dependent on monomer immersion duration, and the concentration of monomers...

Transition metal oxides (TMOs) represent a wide set of materials with a broad range of functionalities, including superconductivity, magnetism, and ferroelectricity, which can be tuned by careful choice of parameters such as strain, oxygen content, and applied electric and magnetic fields [1-4]. This tunability makes TMO’s ideal candidate materials for use in developing novel information and...

Hydrates are a rich and diverse class of materials that display a wide range of structures and properties – a feature that is only exaggerated when they are subjected to high-pressures. Consequently, these have implications on our understanding of many outer solar system bodies, where hydrates are amongst the dominant materials found there.
For Europa and Ganymede, two moons under...

One of the simplest models exhibiting one dimensional (1D) frustrated quantum interactions is the so called J1-J2 model. In this model competing ferromagnetic nearest-neighbour interactions (J1>0) and antiferromagnetic next-nearest-neighbours (J2<0) can give rise to novel phenomena such as multiferroicity for spiral spin states. Linarite, PbCuSO¬4(OH)2 is a natural mineral ideally suited to...

Rare earth orthoferrite RFeO3 is a family of perovskite with fantastic property, such as ultra-fast spin switching[1], photomagnetic excitation[2]and multiferrocity[3]. These properties usually determined by their magnetic structure and unique spin reorientation(SR) effect. The antisymmetric interaction(DM interaction)[4] induce a weak ferromagnetism at room temperature, while the...

The storage and recovery of electrical energy is widely recognized as one of the most important areas for energy research. Although renewable energy such as i.e. wind and solar generated electricity is becoming increasingly available in many countries including Australia, these sources provide only intermittent energy. Thus, energy storage systems are required for load levelling, allowing...

Chromism refers to a change in optical absorption of a material upon application of stimulus; e.g. photochromism – light; thermochromism – heat; electrochromism – electric charge; magnetochromism – magnetic field. This phenomenon has wide applications, in for example so-called ‘smart glass’ which can be switched from a transparent to opaque state through the application of voltage, heat, or...

Controlling material properties by strain is one of the main concepts of thin film growth technology. By altering the order parameter in ferroic materials with which the lattice is coupled, new properties can be achieved, e.g. in perovskite SrCoOx which was identified as a parent phase of strong spin-phonon coupling materials. Here, we present results on a strain-induced...
