Academic year: 2010-2011 Course code module GSNAFY01K00022 Semester: 2nd semester Credits: 3 Study load (hours) 84 Theory (hours): 10,00 Practice/Exercises(hours): 20,00 Other (hours): Part-time program: 1/2 Instructor(s) Luc Van Vaeck Language of instruction: English Semester exam information: exam in the 2nd semester Contract restriction information: 1. Prerequisites *Algemene competenties basic chemistry *Sequentiality None 2. Objectives (expected learning outcomes) - insight in the methods for chemical analysis at the nano-scale - capability to apply this knowledge to a problem of qualitative and quantitative local analysis - knowledge of the specific requirements of chemical analysis at this scale - experience with the possibilities of advanced chemical nano-analysis methods - insight in the role of chemical nano-analysis for the development and preparation of nanomaterials 3. Course content A short introduction (10 h) deals with the use of primarily mass spectrometric methods for the local analysis of elements and molecules in solid samples with high lateral and/or depth resolution. The most important methods are static secondary ion mass spectrometry (S-SIMS) and laser microprobe mass spectrometry (LMMS).  In addition to the functional principles of method and instrumentation, ionisation and fragmentation mechanisms of organic and inorganic analytes are covered. This introductory tutorial prepares the student for the practical part (20 u) where experiments, involving all the steps of an analysis (making the nanofibres, preparation of standards for calibration and quantification, use of advanced instrumentation, data processing and interpretation). The test case involves the qualitative and quantitative analysis of polymeric nanofibres made by electrospinning and analysed with SEM and AFM (morfological) and with  S-SIMS (chemical).  The student operates the instruments but there is technical assistance available. 4.
