A Rapid Electrochemical Impedance Spectroscopy and Sensor-Based Method for Monitoring Freeze-Damage in Tangerines

Albelda Aparisi, Pablo; Fortes Sánchez, Elena; Contat-Rodrigo, L; Masot Peris, Rafael; Laguarda-Miro, Nicolas (Institute of Electrical and Electronics Engineers, 2021-05-15)

[EN] This study focuses on the analysis and early detection of freeze-damage in tangerines using a specific double-needle sensor and Electrochemical Impedance Spectroscopy (EIS). Freeze damage may appear in citrus fruits ...
Application of a Montecarlo based quantitative Kramers-Kronig test for linearity assessment of EIS measurements

Giner-Sanz, Juan José; Ortega Navarro, Emma María; Pérez-Herranz, Valentín (Elsevier, 2016-08-10)

Electrochemical Impedance Spectroscopy (EIS) is a very powerful tool to study the behaviour of electrochemical systems. Three conditions must be fulfilled during EIS measurements: causality, linearity, and stability. If ...
Bimetallic electrocatalysts (Pt-M) supported on single-wall carbon nanotubes for hydrogen and methanol electrooxidation in fuel cells

Maya-Cornejo, J.; Garcia-Bernabe, Abel; Compañ Moreno, Vicente (Elsevier, 2018-01-11)

[EN] A series of Pt-Ru and Pt-Mo bimetallic catalysts were prepared via a chemical reduction method by bubbling CO to form carbonyl compounds as metal precursors. In both cases the Pt-Ru and Pt-Mo bimetallic electrocatalysts ...
Conducting fabrics of polyester coated with polypyrrole and doped with graphene oxide

Molina Puerto, Javier; Zille, A.; Fernández Sáez, Javier; Souto, A. P.; Bonastre Cano, José Antonio; Cases Iborra, Francisco Javier (Elsevier, 2015-06)

Polyester (PES) has been coated with polypyrrole (PPy) to produce conducting fabrics. Graphene oxide (GO) has been used in different concentrations (10, 20 and 30% weight) as counter ion to neutralize the positive charges ...
Electrochemical behavior of near-beta titanium biomedical alloys in phosphate buffer saline solution

Dalmau Borrás, Alba; Guiñón Pina, Virginia; Devesa Albeza, Francisco; Amigó Borrás, Vicente; Igual Muñoz, Anna Neus (Elsevier, 2015-03-01)

The electrochemical behavior of three different near-β titanium alloys (composed by Ti, Nb and Sn) obtained by powder metallurgy for biomedical applications has been investigated. Different electrochemical and microscopy ...
PLS multivariate analysis applied to corrosion studies on reinforced concrete

Monzón, Pablo; Ramón Zamora, José Enrique; Gandía-Romero, Jose M.; Valcuende Payá, Manuel Octavio; Soto Camino, Juan; Palací-López, Daniel (John Wiley & Sons, 2019-02)

[EN] There are few techniques available to calculate the corrosion rate (i(corr)) of reinforcing steel in concrete structures. This is due not only to a lack of instrumentation but also because it is necessary to take into ...
Synergistic effect between hydrodynamic conditions during Ti anodization and acidic treatment on the photoelectric properties of TiO2 nanotubes

Sánchez Tovar, Rita; Fernández Domene, Ramón Manuel; Martinez Sanchez, Alejandro; Blasco Tamarit, María Encarnación; García-Antón, José (Elsevier, 2015-10)

In the present work, the combined influence of controlled hydrodynamic conditions during Ti anodization and the acidic treatment with HClO4 on the photoelectric properties of mixed anatase/rutile TiO2 nanotubes has been ...
Tracking homogeneous reactions during electrodialysis of organic acids via EIS

Martí Calatayud, Manuel César; Evdochenko, E.; Bär, J.; García Gabaldón, Montserrat; Wessling, M.; Pérez-Herranz, Valentín (Elsevier, 2020-02-01)

[EN] Organic acids are highly valuable platform chemicals that can be obtained from bioresources and subsequently transformed into a wide spectrum of profitable consumer goods. After their synthesis, organic acids need to ...
