This article reviews the electrochemistry and electroanalytical applications of carbon paste-based electrodes, sensors, and detectors on the occasion of the half-of-century anniversary since the discovery of carbon paste. The review (with 333 references) has been prepared in the form of a retrospective compilation presenting the field by means of various facts, notes, data, surveys, and summaries, including numerous rarities or curiosities that illustrate the individual achievements and milestones. Carbon paste-based electrodes are discussed in their entirety by covering all important areas of the field, starting from basic characterization of carbon paste as the electrode material, via its typical physicochemical and electrochemical properties or specific features, up to a representative documentation of their applicability in electrochemical and electroanalytical measurements.

“…Considering that the modification of the diatomite by PAH occurred because PAH has an amine group, a peak indicating the presence of nitrogen could be expected. 30 The N1s peak at 399.55 eV can be deconvoluted into two nitrogen species: a species that looks like an unprotonated amine at 399.2 eV and the protonated amine (NH 3+ ) at 401.2 eV in Figure 4B. The N1s peaks in Figure 4B and C shifted slightly from 399.55 to 401.86 eV.…”

Abstract:To fabricate high-strength diatomite-based ceramics for dental applications, the layer-by-layer technique was used to coat diatomite particles with cationic [poly(allylamine hydrochloride)] and anionic [poly(sodium 4-styrenesulfonate)] polymers to improve the dispersion and adsorption of positively charged nano-ZrO 2 (zirconia) as a reinforcing agent. The modified diatomite particles had reduced particle size, narrower size distribution, and were well dispersed, with good adsorption of nano-ZrO 2 . To determine the optimum addition levels for nano-ZrO 2 , ceramics containing 0, 20, 25, 30, and 35 wt% nano-ZrO 2 were sintered and characterized by the three-point bending test and microhardness test. In addition to scanning electron microscopy, propagation phase-contrast synchrotron X-ray microtomography was used to examine the internal structure of the ceramics. The addition of 30 wt% nano-ZrO 2 resulted in the highest flexural strength and fracture toughness with reduced porosity. Shear bond strength between the core and veneer of our diatomite ceramics and the most widely used dental ceramics were compared; the shear bond strength value for the diatomite-based ceramics was found to be significantly higher than for other groups (P , 0.05). Our results show that diatomite-based nanocomposite ceramics are good potential candidates for ceramic-based dental materials.

Abstract:In this review (with 500 refs), both electrochemistry and electroanalysis with carbon paste-based electrodes, sensors, and detectors are of interest, when attention is focused on the research activities in the years of new millennium. Concerned are all important aspects of the field, from fundamental investigations with carbon paste as the electrode material, via laboratory examination of the first electrode prototypes, basic and advanced studies of various electrode processes and other phenomena, up to practical applications to the determination of inorganic ions, complexes, and molecules. The latter is presented in a series of extensive tables, offering a nearly complete survey of methods published within the period of [2001][2002][2003][2004][2005][2006][2007][2008]. Finally, the latest trends and outstanding achievements are also outlined and future prospects given.© Versita Warsaw and Springer-Verlag Berlin Heidelberg.
