“…Ni 2+ , etc. 39 Therefore, it is firstly assumed that the capacity increase in the present work shown in Fig. 6a is ascribed to the substitution of Na + by Li + during the lithium insertion and extraction, in other words, the Na cations in the tunnels were extracted during the charge process, and then more lithium ions were inserted into the host materials in the following discharge process, as a result, the discharge capacity was increased in the initial stage and stabilized at a relative high capacity.…”

“…TAA hydrolysis [18][19][20], the use of TAA as precipitant reagent, as well as the various methods of quantitative determination by precipitation [21,22], amperometric or coulometric titration [23][24][25], redox reactions [26,27], potentiometry [28], utilization in precipitation and determination of various elements [29][30][31][32], anodization of mercury [33], cathodic stripping voltammetry [34,35], and even determination of TAA and a series of other thioamides by anodic voltammetry at solid metal electrodes [36,37], and associated problems concerning sulfide and H 2 S electrochemical oxidation or detection [38,39] have been experimented or applied. The common solid electrodes have rarely been tested for anodic determination of thioamides, with the exception of the application of pulsed amperometric detection (PAD) method [36] and new direct applications, such as determination of organic sulfur-containing compounds [3,40,41] and sulfide oxidation [38] at BDD, determination of thiourea at a BDD electrode [3] or thiourea at a copper oxide-copper electrode [2].…”

TAA is a harmful, presumptive pollutant in tap waters and waste waters. Several alternatives have been tested as new possibilities for the anodic determination of TAA in aqueous solutions, simulated waste waters and tap water. The electrochemical behaviour of thioacetamide (TAA) was investigated at a boron-doped diamond (BDD) electrode both in unbuffered 0.1 M Na 2 SO 4 and buffered solutions as supporting electrolytes. The anodic oxidation of TAA showed well-defined limiting currents or current peaks and a good linearity of the amperometric signal vs. concentration plots. The analytical parameters of sensitivity, RSD and LOD, obtained under various experimental conditions, suggest the suitability of the BDD electrode for electroanalytical purposes. Low fouling effects, good reproducibility and stability, as well as the sharpness of the amperometric signals in both unbuffered/ buffered acidic or neutral media, highly superior to those obtained using a glassy carbon (GC) electrode, recommend the unmodified BDD electrode as a promising potential amperometric sensor for environmental applications, regarding the direct anodic determination of TAA in aqueous media.

“…The conductivities of these films were decreased by exposure to NH 3 vapors. The sensing mechanism is explained by the compensation effect [9][10][11]. it can be seen from the figures, the conductivities of polymers show marked changes when exposed to NH 3 gas.…”

MnO 2 -Doped Polyaniline/Poly (Vinyl alcohol) thin films were prepared chemical oxidative polymerization, using microwave oven technique on glass substrate. These thin films prepared by using Analytical Reagent grade solutions of Polyaniline, Poly (Vinyl alcohol), MnO 2, primary dopant hydrochloric acid are mixed in stoichiometric proportion. The solutions were kept in microwave for 10 sec then oxides with ammonium peroxydisulphate oxidant, then after kept in water bath to obtain the uniform thin films. Films were dries it in air medium for an hour. The electrical and gas sensing properties of these films were investigated. MnO 2, Doped Polyaniline/Poly(Vinyl alcohol) thin films showed better ammonia and trimethyl ammine vapour response as compared to undoped Polyaniline / Poly (Vinyl alcohol) thin films. The gas response was observed to be increased with their stoichiometric composition of films.
