It was recently proposed to use small groups of trapped ions as qubit carriers in miniaturized electrode arrays that comprise a large number of individual trapping zones, between which ions could be moved [1, 2]. This approach might be scalable for quantum information processing with a large numbers of qubits. Processing of quantum information is achieved by transporting ions to and from separa...

We assessed the magnitude of the errors in ionized-calcium measurements resulting from changes in electrolyte composition for three different ion-selective electrodes: the Orion Model 93-20, the Radiometer F2112, and the Simon neutral carrier membrane electrode. We attempted to distinguish between errors arising from changes in calcium ion activity and those due to interferences in the electrod...

fluoride is recognized as an effective agent for dental caries prevention. generally, the main source of fluoride intake is drinking water. in this study, fluoride content in 18 commercial brands of bottled waters was investigated. six samples from each batch of 18 iranian commercial brands of bottled waters were supplied. the fluoride content of samples was analyzed by fluoride ion selective e...

2-amino-n-benzthioazolyl benzamide (abtb) was synthesized, characterized and used for thefabrication of a potentiometric sensor for cu2+ metal ions. the electrode exhibits linear response to cu(ii) over a wide concentration range (4.79×10 -8 – 1.85×10 -1 m) with nernstian slope of 30 ± 1.5 mvper decade. the electrode can be used in the ph range from 2 to 9. it has a fast response time of about1...

in this work, the results concerning to the mean activity coefficient measurements for nacl in the (glycerol + water) system using the potentiometric method are reported. the potentiometric measurements were performed on the galvanic cells without liquid junction of the type: ag|agcl|nacl (m), glycerol (wt%), h2o (1 - wt)%|na-ise, in various mixed solvent systems containing 0, 5, 10, 20 and 30 ...

a simple, precise, rapid and low-cost potentiometric method for diclofenac determination in pharmaceuticals is proposed. a new diclofenac-sensitive electrode was constructed by incorporating the diclofenac ion pair complex with butyl rhodamine b into graphite matrix. the electrode exhibited a linear response over the concentration range of 1 × 10-4 – 5 × 10-2 mol l-1, a detection limit of 3.9×1...

fabrication of a cysteamine (ca) self-assembled monolayer (sam) modified gold electrode insitufunctionalized with l-lysine (lys) is presented and described. the fabricated electrode was used forhighly selective and sensitive accumulation and the determination of copper ions (cu2+) in a nanomolarconcentration. techniques like cyclic voltammetry (cv) and electrochemical impedance spectroscopy (ei...

the electrochemical behavior of a modified carbon paste electrode (mcpe) with n,n′ethylenbis(salicylideneiminato)copper(ii) complex ([cu(ii)-salen]) was investigated as a newsensor for cystein. the britton-robinson buffer with ph 5, 10% modifier in electrode, potentialscanning rate of 20 mvs-1 and puls height of 50 mv were used as the optimum condition for thedetermination of cysteine using car...

In this paper, the effect of cationic and anionic ion sizes on the charge storage capability of graphene nanosheets is investigated. The electrochemical properties of the produced electrode are studied using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) techniques in 3M NaCl, NaOH, and KOH electrolytes. Scanning electron microscopy (SEM) is used to characterize the mi...
