      abstract     = {We used spatially-resolved NEXAFS (near-edge x-ray
                      absorption fine structure) spectroscopy coupled with
                      microscopy to characterize the electronic, structural and
                      chemical properties of bipolar resistive switching devices.
                      Metal/TiO2/metal devices were electroformed with both bias
                      polarities and then physically opened to study the resulting
                      material changes within the device. Soft x-ray absorption
                      techniques allowed isolated study of the different materials
                      present in the device with 100 nm spatial resolution. The
                      resulting morphology and structural changes reveal a picture
                      of localized polarity-independent heating occurring within
                      these devices initiated by and subsequently accelerating
                      polarity-dependent electrochemical reduction/oxidation
                      processes.},
