Article
Full-text available
Kaolinite-rich Cretaceous clay sediment samples from Burgos (Spain) have been analyzed by elemental analylis, X-ray fluorescence, inductively coupled plasma mass spectrometry, X-ray diffraction and different spectroscopic techniques, as Fourier Transform Infrared, ultraviolet-visible and electron paramagnetic resonance. The clay sediment samples ma...

The Early Bronze Age ceramic collection found into the caves of La Llana and El Toral III in Asturias (Spain) presents common decoration like those found in the centre of Cantabrian Spain from the same period, which resemble others found in the Ebro valley and Atlantic Europe. Therefore, the main objective of this work it is to identify the raw mat...
Article
A novel methodology to prepare sensors based on carbon nanostructures electrodes modified by metal nanoparticles is proposed. As a proof of concept, a novel bismuth nanoparticle/carbon nanofiber (Bi-NPs/CNF) electrode and a carbon nanotube (CNT)/gold nanoparticle (Au-NPs) have been developed. Bi-NPs/CNF films were prepared by 1) filtering a dispers...

Spectroelectrochemistry (SEC) is a multi-response technique that allows the simultaneous observation of a physico-chemical phenomenon from different points of view. In electrochemistry, although most experiments are conducted under semi-infinite diffusion conditions, the performance of analysis under thin-layer conditions, for example a small volum...
Article
The purpose of this work is to develop simple and reproducible ways to fabricate carbon nanofibers (CNFs) electrodes. Disposable CNFs electrodes were fabricated after filtering CNFs through polytetrafluoroethylene filters (PTFE), using directly as electrodes these filters with the CNFs film. The electrochemical behaviour of CNFs/PTFE electrodes wer...

The use of single walled carbon nanotubes (SWCNTs) networks as material for electrodes is highly promising for electrochemical applications1. Meanwhile, spectroelectrochemistry is an in-situ auto-validated multi-response technique that studies the spectroscopic evolution of an electrochemical process. Taking as reference these two topics, the main...
Article
A really easy method to transfer commercial single-walled carbon nanotubes (SWCNTs) to different substrates is proposed. In this paper, a homogeneous transference of SWCNTs films to non-conductor and transparent supports such as polyethylene terephthalate, glass and quartz, and to conductor supports such as indium tin oxide, aluminium, highly order...

A new long-optical-pathway spectroelectrochemical cell for absorptometric measurements in the UV-Vis region was developed. This cell consists of two optical fibers brought face to face and fixed on the working electrode support. As a proof of concept, the spectroelectrochemical cell was applied to the determination of catechol using a press-transfe...
Article
A simple method for the fabrication of optically transparent electrodes (OTE) from commercial single-walled carbon nanotubes (SWCNT) is presented. We disperse SWCNT in organic solvents, avoiding surfactants. Films obtained by filtering are transferred to non-conductive polymer substrates only by pressure, avoiding the chemical removing of the filte...

A new composite material based on the electrochemical generation of a layer-by-layer structure of polyaniline (PANI) and Pt particles has been prepared. The number of layers and the nature of the external layer (PANI or Pt) determine the electrocatalytic performance of the composite for the oxidation of methanol. We demonstrate that the layer-by-la...

A new spectroelectrochemical flow cell is presented and its capability to provide a better understanding of reaction mechanisms is illustrated with the study of the electrosynthesis and characterization of a conducting polymer, polyaniline (PANI). A spectroelectrochemical study of electropolymerization of aniline under flow conditions has been perf...

A methodology for the determination of Zn(II), Cd(II) and Pb(II) directly in dissolved honey samples by potentiometric stripping analysis with a flow cell is proposed. Heavy metals in honey are of interest not only for quality control, but can be used also as an environmental indicator. In this work honey samples were collected in different places...

This paper provides a review that summarizes several examples of the literature from 1980 to 2003, to illustrate the applications of stripping potentiometry for the determination and speciation of arsenic in several samples. A discussion on the main advantages of stripping potentiometry in comparison with other electrochemical methods employed for...
