Effect of partial pressure on product selectivity in Cu-catalyzed electrochemical reduction of CO2

Honeycomb-like porous 3D nickel electrodeposition for stable Li and Na metal anodes

Li and Na metals have the highest theoretical anode capacity for Li/Na batteries, but the operational safety hazards stemming from uncontrolled growth of Li/Na dendrites and unstable electrode-electrolyte interfaces hinder their real-world applications. Recently, the emergence of 3D conductive scaffolds aimed at mitigating the dendritic growth...

Electrodeposition of bismuth telluride thermoelectric films from a nonaqueous electrolyte using ethylene glycol

Ethylene glycol was studied as an electrolyte for the electrodeposition of thermoelectric bismuth telluride films by cyclic voltammetry, rotating ring disk electrode and electrochemical quartz crystal microbalance (EQCM). The reduction of both Bi3+ and Te4+ ions proceeds in one step without the formation of intermediates at potentials more...

Patterned electrodeposition of interconnects using microcontact printing

Microcontact printing combined with electroless deposition is a potential low cost technique to make electrical interconnects for opto-electronic devices. Microcontact printed inhibitors locally prevent electroless deposition resulting in a pre-defined pattern of metal tracks. The inhibition of electroless Ni deposition on Pd-seeds and on indium...

Low resistive trasparent conductors with metallic grids: Modeling and experiments

At present, transparent conducting oxides (TCOs) are still superior in performance to most other transparent conductors. Results on opto-electronic modeling and design optimization of TCOs are presented using a monolithically integrated CIGS cell configuration as case. For various cell dimensions and TCO characteristics, the cell output was...

Measurement of Seebeck coefficient of electroplated thermoelectric films in presence of a seed layer

Effect of the seed layer on Seebeck coefficient measurement of electroplated thermoelectric films was quantitatively analyzed. It is found that sheet, rather than bulk resistance of the seed layer, or more precisely its relative comparison to sheet resistance of the film, determines the effects. The analysis reveals that the seed layer's effect...

Electrodeposition of contact grids on thin film solar cells

Electrodeposition and corrosion resistance of nanocrystalline white bronze (CuSn) coatings

For jewellery applications electroplated white bronze (CuSn) was investigated as undercoating for noble metal finishes as alternative to nickel. A strongly acidic plating bath was developed with an organic additive to suppress hydrogen evolution and obtain bright coatings. An electrochemical study of the bath shows that the additive strongly...

Bioaerosol detection by aerosol TOF-mass spectrometry: Application of matrix assisted laser desorption/ionisation

In previous publications the use of an aerosol time of flight mass spectrometer was reported for the on-line measurements of aerosols (Weiss 1997, Kievit 1995). The apparatus is capable of measuring the size as well as the chemical composition, by the use of Laser Desorption/Ionisation (LDI), of an aerosol particle. A drawback of LDI principle...
