We have developed electrochemical liquid cells for transmission electron microscopy (TEM), which allows imaging of electrochemical processes in liquid electrolytes with high spatial resolution in situ (Fig. 1). Using this set up, we study electrochemical deposition and dissolution of lead dendrites on gold electrodes immersed in an aqueous solution of lead nitrate. Observation reveals lead dend...

Magnetic layers and layered structures with defined physical properties are of high interest for magnetoelectronic and magnetoelectromechanical applications as well as for magnetic data storage. New deposition technologies become more important in industrial branches for magnetic applications. Electrochemical deposition methods are favoured due to their low costs compared to physical deposition...

Li-rich layer-structured cathode thin films are prepared by pulsed laser deposition. X-ray diffraction (XRD), field emission scanning electron microscope (FESEM), X-ray photoelectron spectroscopy (XPS) and electrochemical testing in half battery cells are used to characterize crystal structure, surface morphology, chemical valence states and electrochemical performance of these thin films, resp...

Bamboo-type TiO2 nanotube arrays prepared via anodic oxidation are modified with Ag nanoparticles by pulsed electrochemical deposition, for improved lithium-ion intercalation property as the anode material in lithium-ion batteries. Heat treatment converts as-formed nanotubes into anatase for Ag deposition. Bare and Ag-modified nanotubes are cycled at a current density of 800 μAcm between 1.0 an...

Electrode materials play a decisive role in almost all electrochemical energy storage devices, determining their overall performance. Proper selection, design and fabrication of electrode materials have thus been regarded as one of the most critical steps in achieving high electrochemical energy storage performance. As an advanced nanotechnology for thin films and surfaces with conformal interf...

A method for the preparation of smooth deposits of Pt on Au nanorods is described, involving sequential deposition steps with selective blocking of surface sites that reduces Pt-on-Pt deposition. The Au-Pt nanorods prepared by this method have higher long-term stability than those prepared by standard Pt deposition. Electrochemical data show that the resulting structure has more extended region...
