MACAL – Material Analysis Centre at Arrhenius Laboratory
MACAL (Materials Analysis Centre at Arrhenius Laboratory) supervises the use of a large part of instruments at the Department of Materials and Environmental Chemistry (MMK), Stockholm University, with the exception of electron microscopes and related equipments, which are supervised by EMC (Electron Microscopy Centre). The department has a long tradition and strong scientific competence in structural characterization by X-ray and electron diffraction and has excellent experimental facilities for materials characterizations. MACAL was established to ensure that equipments of general interest are working and available to researchers at the department and to external users.
For each instrument there is a person who is responsible for its economy and that the instrument is available. For each instrument there is also an operator who is responsible for its maintenance, training of new users, approval of users as independent users and, for some equipments, serving external users.
The major aims of MACAL are:
- To coordinate the department's competence on materials characterization.
- To ensure that the instrumentation is fully functional and efficiently used.
- To allocate at least one instructor for each instrument and provide practical training.
- To advertise our expertise as consultants in the field of materials characterization.
- The main instruments that are currently under MACAL includes:
- Thermal analysis (TG,DSC,DTA)
- IR spectrometer and microscope
- Surface area measurements
- Quartz crystal balance
- X-ray powder diffraction
- X-ray single crystal diffraction
- Confocal microscope
- Scanning probe microscopes
- Physical property measuring system
- Solid state NMR
- Spark plasma sintering equipment
- Structural characterisation by X-ray powder diffraction (two Panalytical PRO MRD diffractometers + reaction chamber for measurements up to 900C) and single crystal diffraction (Oxford Excalibur diffractometer with CCD detector).
- Physical property measurements (Quantum Design, liquid He – 400 K, electronic and thermal conductivity, Hall measurements, magnetic susceptibility).
- AFM and confocal microscopy
- IR and solid state NMR spectroscopy
- Gas adsorption measurements
- Synthesis by spark plasma sintering
Note! The information on this site has to be revised, please contact us for more updated information. The charges for use of instruments within MACAL are set individually for each instrument by the person responsible for the instrument in agreement with the management of MACAL.
Different charges are set depending on whether the user/customer is internal or external and depending on whether operator help and/or data evaluation is required. By internal use is meant research work within non-commercial research projects with named persons, employed or equivalent, at the department and teaching. Commissions for others are considered as external work. Researchers that want to perform experiments themselves (mainly for long term users) have to participate in training and obtain a certificate showing that they have sufficient skills to run the instrument. Please contact us for more information.
We also provide full characterisation services, preferably on a long term collaboration basis. A special agreement needs then to be established. Please contact us for more information.
Priority is given to the research projects within the department and long term external users.
