Plasma-Assisted Fabrication of Molecularly Imprinted NiAl-LDH Layer on Ni Nanorod Arrays for Glyphosate Detection.

An inorganic-framework molecularly imprinted NiAl layered double hydroxide (MI-NiAl-LDH) with specific template molecule (glyphosate pesticide, Glyp) recognition ability was prepared on Ni nanorod arrays (Ni NRAs) through electrodeposition followed by a low-temperature O plasma treatment. The freestanding Ni/MI-NiAl-LDH NRA electrode had highly enhanced sensitivity and selectivity. The electrocatalytic oxidation of Glyp was proposed to occur at Ni centers in MI-NiAl-LDH, and the current response depended linearly on the Glyp concentration from 10.

On the electrodeposition of tantalum from three different ionic liquids with the bis(trifluoromethyl sulfonyl) amide anion.

The electrodeposition of Ta from TaF(5) was studied in three different ionic liquids, namely in 1-butyl-1-methylpyrrolidinium bis(trifluoromethyl sulfonyl) amide, 1-ethyl-3-methylimidazolium bis(trifluoromethyl sulfonyl) amide and 1-methyl-3-propyl imidazolium bis(trifluoromethyl sulfonyl) amide. The electrochemical quartz crystal microbalance (EQCM) was used together with electrochemical techniques for characterizing in situ the electrodeposition process. With the help of the EQCM we could identify the stoichiometry of the electrodeposited species.

Magnetic field effects on electrochemical metal depositions.

This paper discusses recent experimental and numerical results from the authors' labs on the effects of moderate magnetic (B) fields in electrochemical reactions. The probably best understood effect of B fields during electrochemical reactions is the magnetohydrodynamic (MHD) effect. In the majority of cases it manifests itself in increased mass transport rates which are a direct consequence of Lorentz forces in the bulk of the electrolyte.
