Materials Engineering

Dr. Tania Claudio Weber has worked extensively with functional nanopowders and nanostructured bulk materials. As a practical example, she has optimized the manufacturing process for a low-cost nanostructured silicon material so that the thermoelectric properties are improved by a factor of 30.

In order to achieve such superior properties in functional materials, it is vitally important to control phase, composition, purity and particle size of the product during the manufacturing process. Bond Consulting can help you to determine the crystal structure and phase composition of powder and bulk samples with X-ray diffraction (XRD), neutron scattering and transmission electron microscopy (TEM). Particle size in powders and bulk materials can be measured at the nanometer scale with TEM, XRD, pair distribution function (PDF) and small-angle X-ray scattering (SANS). Magnetic properties are accessible using neutron scattering. A wide array of methods to determine the elemental composition and purity of a sample are available, including X-ray fluorescence (XRF), energy-dispersive X-ray spectroscopy (EDX), prompt gamma ray activation analysis (PGAA), Rutherford backscattering spectroscopy (RBS), various plasma emission and absorption methods, X-ray photoelectron spectroscop (XPS), and many others. Bond Consulting helps you to find the optimal combination of methods to get straight to your goals with a minimum of headache and expenses.

Sometimes the bread-and-butter methods just won't cut it. Dr. Tania Claudio Weber is an expert for materials analysis using neutrons and synchrotron radiation and has excellent contacts within this scientific community. Parameters such as crystal structure, phase, particle size, magnetic properties and composition can be determined with unparalleled precision. Synchrotron radiation is particularly suitable when only minute sample quantities in the µg and mg range are available. These methods are provided by heavily overbooked major research facilities where proposals for experiments undergo a strict review and selection process. If such an analysis is required for your task at hand, Bond Consulting can select the best scientific cooperation partners, methods and facilities. We write a scientific proposal together with the partners and handle the entire submission and selection process for you. After acceptance, we can perform the experiments at the facilities and analyse the resulting data in order to draw conclusions relevant for your task.
