The main objective of this work was to use reline deep eutectic solvent,containing Al(III)ions,for the electrochemical study of the nucleation and growth of aluminum onto a glassy carbon electrode at different temperatures and angular speeds(ω)of the working *** order to fulfill this,electrochemical and surface characterization techniques were *** was found that as temperature increased,the onset of the Al(III)DES reduction occurred at less negative potentials while the current peak of the voltammograms *** indicate that Al deposition thermodynamics and kinetics were ***,no anodic current was detected due to Al passivation by Al(OH)_(3)(s)andγ-Al_(2)O_(3)(s).Atω=0 r/min,the Al deposition chronoamperograms were analyzed by a theoretical model comprising Al 3D diffusion-controlled nucleation and growth and residual water ***,those recorded at different angular speeds were analyzed with a theoretical model where adsorption−desorption and diffusion-controlled nucleation−growth occurred *** deposits were characterized by SEM,EDX,XpS and ***ω=0 r/min,formation of well distributed nanoparticles((78.1±9.5)nm)was observed,while atω=900 r/min the deposit was formed by multiple 10μm diameter leaf-like flat microstructures,composed by Al,Al(OH)_(3)(s)andγ-A2O3(s).

Objective: To analyse clinical and therapeutic aspects of epilepsy secondary to ulegyria in adults. patients: Out of 1,020 consecutive patients studied at a tertiary care epilepsy centre, eight cases of ulegyria were identified. All patients had comprehensive clinical evaluation, neuropsychological testing, interictal EEG, and brain magnetic resonance imaging (MRI). In addition, five patients had video-EEG monitoring. Ulegyria was confirmed by histological analysis in two patients who had successful epilepsy surgery. Results: All patients had a histor y of perinatal asphyxia. In four of them there was psychomotor developmental del ay. Mean age at onset of seizures was 5.8 years (range first week to 21 years). Brain MRI demonstrated predominant involvement of occipito-parietal cortical an d subcortical areas. This posterior distribution of lesions was also supported b y the presence of auras with occipital and parietal semiology in six patients, a nd signs of visuospatial dysfunction in five. Four patients had medically refrac tory epilepsy and two of them had significant improvement with surgical treatmen t. Conclusions: In this group of adult epileptic patients with ulegyria brain MR I, ictal semiology, and neurological examination are consistent with occipital l obe epilepsy. Most patients have severe epilepsy, but in some of them epilepsy c an be controlled with antiepileptic drugs, while in others surgical treatment ca n be effective. Brain MRI criteria of ulegyria are well established, and in two cases it was possible to confirm their diagnosis with histological analysis.
