Time-of-Ñight secondary ion mass spectrometry (ToF-SIMS) and atomic force microscopy (AFM) were utilized to characterize polypropylenes of di †erent stereoregularity (atactic, syndiotactic and isotactic) deposited on gold-or silver-coated mica surfaces. The AFM images clearly revealed distinctive su

✦ Synopsis
The hydration of cement has been studied using the SIMS-Technique. It has been possible to trace the progress of the hydration reaction into the inner region of the cement particles, thus elucidating new aspects of the hydration reaction of cements. The results obtained are in excellent agreement with the data known for the early stages of cement hydration.
