Juan Ruiz et Juan Goytisolo : deux espagnols bilingues ?
No full textQuelle importance doit-on accorder à l'irruption de la langue arabe dans les textes de Juan Goytisolo ? Je pars nécessairement de ce que l'auteur pense lui-même de ce phénomène, ce qui me permettra de faire un détour par l'époque médiévale et de m'intéresser au cas de Juan Ruiz, témoin de la convivencia entre les cultures chrétienne, juive et musulmane qui cohabitent tint bien que mal sur le sol ibérique au temps de la Reconquête et d'Al-Andalus. Je m'attacherai à montrer que l'intérêt que porte Juan Goytisolo aux pérégrinismes et cette tendance qui est la sienne à manifester parfois un bilinguisme marqué sont autant de preuves de son attachement pour le castillan tel qu'il le conçoit, en tint qu'écrivain : c'est-à-dire comme un matériau vivant, source de création.Tachattahte Bahdad Samira.

Characterization of the Electron Transfer Reaction Mechanism of TiOSO4 and MnSO4 in Sulfuric Acid Solution
No full textAn electrochemical characteristic evaluation of the Ti-Mn electrolyte system in sulfuric acid aqueous solution is studied in different acid concentrations with and without the mixing of TiOSO4 and MnSO4 electrolyte system for a redox flow battery application. The reaction mechanism of Mn in sulfuric acid electrolyte is studied using the cyclic voltammetry and the anodic voltage hold techniques. The overall anodic behavior of the Mn system can be described by the oxidation reaction of Mn2+ to MnO2 where Mn3+ is an intermediate species. As the acid concentration increases, less MnO2 is formed on the working electrode and more Mn3+ is formed in the solution; however, due to the instability of Mn3+ in an aqueous solution, Mn3+ undergoes a significant hydrolysis reaction to precipitate as MnOOH in the electrolyte solution. The addition of 1M TiOSO4 to the Mn electrolyte is found to lower the H+ concentration which is believed to increase the amount of MnOOH in the solution and lower the concentration of aqueous Mn3+. The formed MnOOH by the Mn3+ hydrolysis reaction is proven to be electrochemically active if it is deposited on the working electrode. The reaction mechanism of Ti in sulfuric acid electrolyte is studied using the cyclic voltammetry technique. Two electro-active species are found to be electrochemically active within the studied voltage window which are Ti4+, and TiSO42+. In 1M H2SO4, Ti4+ is found to be the dominant electro-active species, and in 3M H2SO4, TiSO42+ is found to be the dominant electro-active species. The addition of 1M MnSO4 to the 1M TiOSO4+3M H2SO4 solution results in a high concentration of undissociated MnSO4, and it is found that the dissociation of MnSO4 to SO42− improve the activity of the redox reaction of the Ti(IV)/Ti(III) couple. With the increase of H2SO4 and the addition of MnSO4 in the Ti electrolyte, the electrochemical behavior of the Ti(IV)/Ti(III) redox couple tends toward the reversibility
Anodically Grown Pt(II) Oxide Microelectrode/Nanoelectrode pH Sensor
No full textThese are the slides from a presentation given at the 2024 AICHE Annual Meeting on 10/29/2024.Platinum electrode availability in electrochemical laboratories makes it attractive as a potentiometric solid-state pH sensor for aqueous solutions. However, challenges have been reported in fabricating anodic-grown platinum oxide potentiometric pH sensors. In this work, cyclic voltammetry in 0.5 M H2SO4 and 1 M NaOH was conducted to assess the effect of acidic and basic solutions on the anodic-grown platinum (II) oxide for designing Pt/Pt(II) oxide pH sensor. Chronoamperometry was also employed to grow a platinum (II) oxide layer on an ultramicroelectrode in both solutions, followed by measuring their potentiometric response in various pH solutions. The platinum (II) oxide manufactured in 1 M NaOH showed a close Nernstian response (~ -60 mV/pH), and was insensitive to dissolved oxygen, cation and anion identities, and molar ionic strength. When the platinum (II) oxide was grown on a platinum nanoelectrode, the response time was ~ 2 seconds for an approximately twelve-fold pH step change. These findings highlight the importance of the solution pH used during platinum oxidation on anodic platinum (II) oxide properties in sensing solution pH. The straightforward approach used in this work for fabricating Pt/PtO microelectrode/nanoelectrode pH sensors by direct oxidation can ease real-time pH measurement in complex aqueous environments

Estimation of Subsurface Structure Using Euler Deconvolution Method of Magnetic Data at the Geothermal Area of Sonai Village and its Surroundings, Konawe Regency
No full textIt has been carried out research with the aim of determining the subsurface structure at the geothermal area of Sonai Village and its surroundings, Konawe Regency. The data used are magnetic data obtained through field measurements at 126 points in the N180oS direction. After the data were subjected to diurnal and IGRF corrections, a residual (local) magnetic field anomaly of around -150 nT to 90 nT was obtained. On the residual magnetic anomaly map which has been reduced to the Pole (RTP), the Euler Deconvolution (ED) method is applied to the Index Structure N=0 to estimate the subsurface structure in the form of the presence of minor faults, and it is known that there are 5 minor faults at a depth of around 9 to 38 meters. Information on the existence of these faults is then used in 2D modeling. Modeling results show that these minor faults cut through two rock layers, which are the layers composed of conglomerate rocks from the Alangga Formation and peridotites as bedrock from the Ultramafic Complex. One of the minor faults closest to the manifestation area (hot spring) is at coordinates around 4o1’12.412” S and 122o7’24.263” E to 4o1’15.532” S and 122o7’19.561” E with a distance of ±15 meters. The existence of these minor faults is thought to be the migration routes for heat flow or conduction to the surface at the geothermal area of Sonai Village and its surroundings
