Coated wire lithium ion selective electrode was fabricated using lithium ionophore-VI, 2-nitrophenyl octyl ether (NPOE) and potassium tetrakis(p-chlorophenyl)borate (KTpClPB) on platinum wire. Lithium ion selective electrode was giving Nernstian response from 10 -1 M to 10 -4 M with a detection limit of 3x10 -5 M. The calibration slope of this lithium ion selective electrode was found to be 58....

The currently high price of gold wire has led to the development of bonding wire made from palladium-coated-copper as a lower cost alternative. Increasing the uniformity of the Pd distribution in free-air balls, formed by melting the wire end with an electric spark, is of interest as it can influence the uniformity of process and reliability. To study this Pd distribution, free-air balls are ma...

The work described here comprises the determination of Fe(III) by ion selective potentiometry using a coated-wire ion-selective electrode (CWISE) based on iron–cyclam complex. Linear Nernstian response for this electrode was obtained over the total Fe(III) concentration range of 1× 10−2 to 1× 10−6 M in 0.05 M HNO3, H2SO4, HClO4, HCl, KNO3 and KCl media, with a slope of 60± 5 mV per decade chang...

A new pyrilamine coated graphite electrode (CGE) based on pyrilamine-tetraphenylborate ion-pair (Pyra-TPB) as electroactive material has been described. The sensor exhibited a linear response with a good Nernstian slope over a relatively wide range of concentration. The membrane film of the electrode made of 3% (w/w) ion-pair, 48.5% DBP (w/w) and 48.5% PVC (w/w). The sensor displays Nernstian r...

the microbial fuel cells (mfcs) are a kind of systems through which the anaerobic bacteriaalong with the oxidation of simple or complicated organic matter in the wastewater can generate the electricpower. this is a modern approach used in generation of the clean and renewable energy. in this research, two pilot laboratories of double-chamber microbial fuel cells were made. one of them contained...
