Organized silica microspheres carrying ferromagnetic cobalt nanoparticles as a basis for tip arrays in magnetic force microscopy
Article Abstract:
A study was conducted to characterize the synthesis of silica microspheres supporting ferromagnetic cobalt nanoparticles. The morphological, magnetic, thermal, and interfacial characteristics of the microspheres were also analyzed. Results indicated that As-prepared cobalt nanoclusters were superparamagnetic and had to be crystallized at 400 degrees C. In addition, the cobalt nanocrystals remained fixed to the silica core to support lateral force imaging without tip induced surface movements.

Time-difference impedance spectroscopy of growing films containing a single mobile charge carrier, with application to surface films on Li electrodes
Article Abstract:
A new approach to analyze the electrochemical impedance spectroscopy (EIS) data for electrodes covered by passivating surface films that grow in time is reported. The time-difference impedance spectra (DIS), which is the difference between two complex impedance curves, Z(omega, T1)-Z(omega, t2) measured after different period of storage, t1and t2 as a function of frequency provide an useful tool for characterizing the nature of the growing passivating films.

Micromorphological studies of lithium electrodes in alkyl carbonate solutions using in situ atomic force microscopy
Article Abstract:
Studies done on the morphology of lithium electrodes in a variety of alkyl carbonate solutions using in situ atomic force microscopy is presented. Workstation was used which was specially built for the study of highly reactive electrochemical systems by AFM and other scanning probe techniques, based on an evacuable, vibration protected glovebox.
