We describe a three-dimensional imaging and analysis study of eight industrial cellular foam morphologies. The foam morphologies were generated by differing industrial processing methods. Tomograms are acquired on an X-ray micro-computed tomography f

Thermal processes are important in areas ranging from biological to advanced materials processing. Here, we present a method for measuring temperature profiles in three dimensions using a combination of two-photon microscopy and calibrated temperatur

The composition of semi-interpenetrating polymer networks (semi-IPNs) based on responsive N-isopropylacrylamide (NIPAAm) hydrogels has been shown to affect the kinetics of the volume phase transition. Several N-alkyl-substituted acrylamides were used

Fluorescence recovery after two-photon photobleaching (TP-FRAP) was used to characterize the diffusion in polymer thin films. Using a two-photon/confocal microscope, a region was bleached inside a fluorophore-doped poly(vinyl alcohol) film. An ellips
