The review article discusses the current status and recent findings of our investigations on the synthesis and characterization of carbon-supported PtRuMo electrocatalysts for direct alcohol fuel cells. In particular, the effect of the carbon support and the composition on the structure, stability and the activity of the PtRuMo nanoparticles for the electrooxidation of CO, methanol and ethanol ...

Five-channel silicon-based microprobes were sputter-coated with carbon, coated with Nafion, and used for both in vivo electrochemical and single-unit electrophysiological recordings. High-speed electrochemical studies were performed in vitro and in vivo, which demonstrated that these multisite probes were capable of monitoring the evoked overflow of monoamines in selected brain regions of the r...

Nanostructured ultrathin films of pendant carbazole-modified polyelectrolytes were fabricated using the layer-by-layer deposition technique in order to correlate the importance of highly ordered structures and well-defined layer composition in electrochemical cross-linking and nanopatterning. Both UV-vis and surface plasmon resonance (SPR) spectroscopy studies indicated differences in the film ...

The complexes of Mn(OAc)3 and/or Mn(acac)3 with nucleic bases and nucleosides (adenine, guanine, xanthine, adenosine and guanosine) have been synthesized in nonaqueous solution. Polarographic and spectroscopic (IR and Visible) methods have been used to establish the active site(s) on the imidazole and pyrimidine rings in the nucleic bases and nucleosides for the intera...

Liposomes with chlorophyll a are model membranes providing a hydrophobic environment for chlorophyll a. Physical and chemical studies on these models could lead to relevant insights for in vivo primary reactions in photosynthetic membranes. The objective of our research was to prove that the spectral and electrochemical features of chlorophyll a allow it to be used as a fluorescence marker and ...

Cobalt oxide films were prepared by electrochemically precipitating the hydroxide and heating it in air to form Co3O4. The resulting oxide films behave as a capacitor. The materials were studied emphasizing their use as either positive or negative electrodes in devices. The capacitance of the material was estimated at different heating temperatures and insight was gained into the charge storage...

Yong-Hui Tian, T-1; George S. Goff, Wolfgang H. Runde, C-IIAC; Enrique R. Batista, T-1 Room-temperature ionic liquids (RTIL) are regarded as green solvents due to their low volatility, low flammability, and thermal stability. RTILs exhibit wide electrochemical windows, and they show potential as media for a variety of electroplating processes. Therefore, understanding the factors dominating the...

Cyclic voltammetry, UV-Vis spectroscopic and molecular docking methods have been used to predict the effect of biologically potent compounds on the DNA proliferation under physiological conditions (pH 7.4 and 4.7). The interaction of organogermanium compounds namely β-o-flourophenyl-γ-bis (8-quinolinoxy) germa-γ-lactone (GLf) and β-methyl-γ-bis (8-quinolinoxy) germa-γ-lactone (GLm) with DNA was...

The present study focuses on effects of operational parameters on electrochemical wastewater treatment for synthetic wastewater. Electro-oxidation has emerged as one of the advanced oxidation processes gaining more attention because it offers many distinctive advantages over other conventional methods such as versatility, high treatment efficiency, safety, amenability of automation and cost eff...
