Title of Speech: Non-Metallic Composites for High Temperature Aerospace Applications 

Abstract: Currently, metal matrix composites (MMCs) are used in high temperature aero-engine applications. MMCs have been under development since 1960s. Noteworthy among the MMCs are long fiber titanium matrix composites (TMCs) that were developed during the 1990s as part of the Integrated High Performance Turbine Engine Technology (IHPTET) program and the Titanium Matrix Composite Turbine Engine Component Consortium (TMCTECC) to substantially increase the aero-propulsion capability. These programs intensified the hunt for high temperature aero-engine materials beyond titanium alloys leading to the development of intermetallic matrix composites (IMCs). The selection of appropriate matrix material for aero-engine applications is primarily driven by consideration of lowering the density and maximizing the operating temperature. Currently Aluminum matrix composite materials are used for the colder part of the engine and IMCs are used for the hotter part where temperatures in excess of 650oC are experienced. However in recent years, non-metallic ceramic matrix composites (CMCs) for high temperature aerospace applications are receiving a great deal of attention because of increased emphasis on ‘Environmentally Responsible Aviation (ERA)’ with the dual aims of improving the engine efficiency and reducing the mass. In addition to various aerodynamic and propulsion technologies that are being researched to achieve the goals of ERA, reduction of aircraft mass has become one of the major drivers in developing new aircraft design concepts, novel materials and manufacturing processes. Composite materials have increasingly been used in recent conventional wing/tube type aircraft e.g. in B787 and A350-1000 aircraft. This paper first reviews the current status of metal matrix composites for aero-engine applications and then describes the recent developments in two widely used composite materials, namely the Polymer Matrix Composites (PMCs) and the Ceramic Matrix Composites (CMCs) for airframe and aero-engine applications, and the challenges they pose in manufacturing. The recent work in improving the mechanical properties of PMCs and CMCs by inclusion of clay nanoparticles and carbon nanotubes and the potential of additive manufacturing for such nanocomposites with nanoscale fillers will also be presented.

Title of Speech: Insights on properties of morphologically complex functional materials using advanced methods at synchrotrons and free electron lasers  

Abstract: The trend of modern nano-technology to invent complex nano-structured and composite materials with improved structural, chemical, electric, magnetic and optical properties has pushed the development and implementation of appropriate characterization methods exploring their structure, dynamics and function at proper spatial, temporal and energy scales. In this respect the complementary capabilities in terms of imaging, spectroscopy, spatial and time resolution of the tools operated at synchrotron and free electron laser facilities have opened unique opportunities to explore the properties of complex functional materials as a function of their size, morphology, composition and operation conditions. Ongoing developments are pushing the lateral and temporal resolution and set-ups allowing for in-situ measurements under realistic operational conditions. The most recent achievements will be illustrated by using selected results from studies of the properties of technologically relevant multicomponent materials following the effects of the chemical ambient, temperature, electomagnetic fields and radiation. The talk will include (i) properties of free-standing nanostructures as a function of composition, dimensions and ambient; (ii) variations in morphology and chemical state of key functional constituents in electrochemical devices as a function of growth or operating conditions; (iii) tracking the ultrafast dynamics triggered by external stimuli with access to elemental and/or magnetic structure of the specimen.

Title of Speech: Atomic-scale tomography of semiconductors and superconductors  

Abstract: Atom Probe tomography have been applied to solve the critical questions in semiconductor and superconductor materials. We have demonstrated that, in the analysis of semiconductor nanowires epitaxially grown from a substrate, the presence of the flat substrate positioned only micrometers away from the analyzed tip apex alters the field distribution and ion trajectories, which provides extra image compression that allows for the analysis of the entire specimen. In InGaAs nanowires, we have revealed and explained: (1) Ga-rich core and In-rich shell structure was grown via different mechanisms; (2) the decomposition rate of the group III precursors determines the In/Ga ratio in the core; (3) The dimension of core increases from 45 to 65 nm and the shape of the core changes from a hexagon to a rounded triangle from the top to the base of the nanowire; (4) The In/Ga ratio and inhomogeneous distributions of group III atoms in the {112}. In order to unravel the magnetism of Co doped ZnO films, we have performed rigorous experiments on Co doped ZnO grown on α-Al2O3 and O-polar ZnO (0001) substrates. In both cases, atom probe tomography confirms a random distribution of Co ion even at the interface region. In the ZnO:Co on α-Al2O3 substrate, the interaction between high density of threading dislocation, dopants, native point defects holds the key to understand the hitherto puzzling ferromagnetism observed in wide variety of doped and undoped semiconductors. However, in the ZnO on the O-polar ZnO (0001) substrate, hydrogen plays a key role in mediating magnetic ordering. Local fluctuations in the distribution of dopant atoms are thought to cause the nanoscale electronic disorder or phase separation in pnictide superconductors. Atom probe tomography has enabled the first direct observations of dopant species clustering in a K-doped 122-phase pnictide. First-principles calculations suggest the coexistence of static magnetism and superconductivity on a lattice parameter length scale over a wide range of dopant concentrations. Our results provide evidence for a mixed scenario of phase coexistence and phase separation, depending on local dopant atom distributions.
