PNIPAM brushes are considered promising surface modifiers to accurately tune cell-substrate interactions. The structure of such brushes in water has been the subject of several experimental studies. On the one hand, force measuring techniques (atomic force microscopy and surface forces apparatus) have been used to probe the repulsive forces resulting from brush compression (Ishida and Biggs 2007, Kidoaki et al. 2001, Kaholek et al. 2004, Plunkett... 

Experimental techniques based on the application of mechanical forces to single molecules in small assemblies have been applied to study the binding properties of biomolecules and their response to external mechanical manipulations. Among such techniques are atomic force microscopy (AFM), optical tweezers, biomembrane force probe, and surface force apparatus experiments (Binning et al., 1986 Block and Svoboda, 1994 Evans et ah, 1995 Israelachvili, 1992). These techniques have inspired us and others (see also the chapters by Eichinger et al. and by Hermans et al. in this volume) to adopt a similar approach for the study of biomolecules by means of computer simulations. 

The experimental techniques described above of charge—discharge and impedance are nondestructive. Tear-down analysis or disassembly of spent cells and an examination of the various components using experimental techniques such as Raman microscopy, atomic force microscopy, NMR spectroscopy, transmission electron microscopy, XAS, and the like can be carried out on materials-spent battery electrodes to better understand the phenomena that lead to degradation during use. These techniques provide diagnostic techniques that identify materials properties and materials interactions that limit lifetime, performance, and thermal stabiity. The accelerated rate calorimeter finds use in identifying safety-related situations that lead to thermal runaway and destruction of the battery. 

The modern availability of sensitive experimental techniques using synchrotron radiation and atomic force microscopy, and fast computers for molecular modeling, has spurred recent intense interest in following the mechanism of polymer crystallization. In spite of the heroic efforts by the... 

By now, the possibility of deposition of granulated Cu, Ni, Pd, Pt, and Au films by laser electrodispersion has been experimentally verified. The structural parameters of the films being formed were studied by various diagnostic techniques, with the most informative results obtained with TEM, atomic-force microscopy (AFM), and X-ray photoelectron spectroscopy (XPS). 

An experimental trial for finding foe freezing point elevation phenomena was conducted, employing foe so-called colloidal-probe Atomic Force Microscopy. A carbonaceous nanospace with slit geometry was successfully made up by this technique.
