Experimental Methods

Chalmers and the Department of Biomaterials at the University of Gothenburg have a very long history of outstanding research in experimental materials science. Corrosion, new materials synthesis for catalysis, electronics, and materials for energy applications are new expanding areas. Advanced material synthesis and characterisation methods are crucial for a successful groundbreaking materials research.

The synthesis includes solid state chemistry, polymeric and biomacromolecular materials, novel composite materials, with new or improved functional properties. Chalmers hosts the state-of-the-art cleanroom facility for thin-film deposition, process and characterisation equipment providing a broad platform for micro- and nano-technology. There is a wide range of analysis methods in-house at Chalmers for studies of structure and dynamics in virtually any system with spatial resolution ranging from millimeters to Ångströms, and time resolution from seconds to femto-seconds.

There is a particular effort devoted to in-situ characterisation of materials. As a special initiative in the Materials Science Area of Advance is the establishment of the SOFT Microscopy Centre for dynamic microscopy, 3 dimensional imaging and microanalysis of biological and soft matter objects.

Chalmers is also involved in the design of a state-of-the-art neutron powder diffractometer for materials science at ISIS, Rutherford Appleton Laboratory and soft X-ray beamlines at MAX-lab techniques as well as in the planning and development of the new ESS and MAX IV facilities in Lund.

Examples of Excellence

Biosensing technology using Quartz Crystal Microbalance (QCM) for studying interactions between sample molecules and a surface. The QCM technique has been developed at the Department of Applied Physics and has resulted in a spin-off company, Q-Sense, founded in 1996.

An outstanding innovation is the combined scanning tunnelling microscope (STM)-transmission electron microscope (TEM) holder enabling in-situ simultaneous dynamical time resolved investigations and direct correlation between structure and properties in the TEM with high spatial resolution. A spin-off company, Nanofactory Instruments AB, has been founded and has continued to further develop the concept.

The molecular microscopy project focuses on molecular biology and genetic engineering experiments, e.g. transcriptomics, proteomics and metabolomics. Different non-linear optical processes,such as Multi-Photon Fluorescence, Second and Third Harmonic Generation (SHG, THG), and Coherent Anti-Stokes Raman Scattering (CARS) are employed.
