Screen-printed electrografted electrode for trace uranium analysis

Novel CeO2-based screen-printed potentiometric electrodes for pH monitoring

“…The screen-printing process was selected as the most appropriate technology for making reproducible electrodes [34,35] and rapidly generating data sets. It involves transferring a thin layer of a conductive ink onto a rigid substrate through the mesh of a screen pattern [41].…”

“…Moreover, these Ce-rich compositions preserved the cubic fluorite lattice of CeO 2 , which has beneficiary properties such as high Oxygen Storage Capacity (OSC) [33]. The screen-printing process was chosen as the most appropriate technology for assembling reproducible electrodes [34,35] and rapidly generating data sets. This technology has been used to develop electrodes based on PdO, TiO 2 , PtO 2 [14], RuO 2 [14,36] and CoO 2 [37].…”

Raman Characterization of Phenyl-Derivatives: From Primary Amine to Diazonium Salts

“…The rise in popularity of aryl-diazonium salts has further resulted from their efficiency in surface functionalization, where covalently attached coatings on (semi)-conducting materials bear a wide range of functional groups [5][6][7][8][9][10][11][12][13][14]. In addition, the grafting can be accomplished by either chemical (spontaneous grafting), electrochemical, or physical methods [5][6][7][8][9][10][11][12]15].…”

“…In addition, the grafting can be accomplished by either chemical (spontaneous grafting), electrochemical, or physical methods [5][6][7][8][9][10][11][12]15]. Surface functionalization using diazonium salts has thus become one of the most powerful methods for coatings [8,13,14] through linking (bio)molecules [16,17], polymers [18][19][20] or nanoparticles [21]. The resulting high-performance materials show improved chemical and physical properties and find widespread application [22].…”

Stripping Voltammetric Determination of Uranium in Water Samples Using Hg-Thin Film Modified Multiwall Carbon Nanotube Incorporated Carbon Paste Electrode

“…Use of mercury thin films reduces the use of toxic metallic mercury compared to the mercury drop. Modified electrodes by a number of ways of modifications of the solid-state electrodes have been investigated and a few among them are, propyl gallate [22], N-phenyl-cinnamohydroxamic acid [23], carbamoyl phosphonic acid [24], self-assembled monolayers of thiols [25,26], nafion [27], calixarenes [28,29], carbon nanotubes [30], and modified graphite electrodes [31]. Recently a relatively simpler method has been proposed based on 6-O-palmitoyl-l-ascorbic acid-modified graphite electrodes [32].…”
