The design of microbial fuel cells (MFCs) should account for realistic conditions to have an MFC considered to be a reliable energy source. For this reason, this study focused on the design of a simple and economical cell, such as a benthonic microbial fuel cell (BMFC). Moreover, it was demonstrated that the stable energy generated in the best configuration of MFCs drives external advanced oxidation processes (electrochemical and electro-Fenton). Finally, a new hybrid cell (BMFC anode and electro-Fenton cathode) was designed to obtain a dual benefit: dye decolourisation and an increase in the produced energy.
Molybdenum release from high burnup spent nuclear fuel at alkaline and hyperalkaline pH

This work presents experimental data and modelling of the release of Mo from high-burnup spent nuclear fuel (63 MWd/kgU) at two different pH values, 8.4 and 13.2 in air. The release of Mo from SF to the solution is around two orders of magnitude higher at pH = 13.2 than at pH = 8.4. The high Mo release at high pH would indicate that Mo would not be congruently released with uranium and would have an important contribution to the Instant Release Fraction, with a value of 5.3%. Parallel experiments with pure non irradiated Mo(s) and XPS determinations indicated that the faster dissolution at pH = 13.2 could be the consequence of the higher releases from metallic Mo in the fuel through a surface complexation mechanism promoted by the OH and the oxidation of the metal to Mo(VI) via the formation of intermediate Mo(IV) and Mo(V) species.

Pantothenate kinase-associated neurodegeneration (PKAN) is a rare autosomal recessive disease characterized by iron deposition in the basal ganglia, primarily in the globus pallidus and substantia nigra. Common clinical manifestations include dystonia, parkinsonism, spasticity, neuropsychiatric disorders and retinal degeneration. PKAN is included in the spectrum of disorders related to neurodegeneration with brain iron accumulation (NBIA), which includes eleven diseases.

In this work the preparation, characterization and performance of Y-zeolite as catalyst for electro-Fentontreatment of pesticides was carried out. Initially iron supported Y-zeolite (Fe-Y) was prepared andevaluated for the degradation of imidacloprid and chlorpyrifos. Kinetic studies determined that thepesticides removal followed a pseudo-first-order kinetic model. However, the reusability of this catalystwas not appropriated and to enhance its recyclability, Fe-Y catalyst was embedded in alginate (Al-Fe-Y). The new catalyst showed similar degradation efficiency; and the recyclability was improved. This studydemonstrated that Al-Fe-Y could be efficiently used to remove commonly pesticides, imidacloprid andchlorpyrifos, from aqueous medium.

BACKGROUND: Proper scaling of cardiac dimensions is of paramount importance in making correct decisions in clinical cardiology. The usual normalization of cardiac dimensions to overall body size assumes an isometric relationship. We sought to investigate these relationships to obtain the best allometric coefficient (AC) for scaling. METHODS: Ninety-seven healthy volunteers were included. The dimensions to be scaled were the left atrial volume, the end-diastolic and end-systolic left ventricular volumes, and the diameter of the tricuspid annulus. A Bayesian statistical analysis was applied with isometric coefficients as priors. RESULTS: The linear correlations between cardiac dimensions and body size were modest, ranging from 0.12 (-0.10–0.32) for the left atrial volume and height to 0.70 (0.58–0.80) for the end-diastolic volume and height. The ACs varied across the different cardiac dimensions and body size measurements. For the best linear relationships, the isometric coefficients were outside the 95% highest density interval of the posterior distribution for the left atrial volume-weight (AC: 0.7; 0.4–0.9) and end-diastolic volume-height (AC: 2.3; 1.7–2.9), whereas they were different from 1 for the left atrial volume-weight, end-diastolic volume, and diameter of the tricuspid annulus-body surface area (AC: 0.6; 0.3–0.8). Not scaling the cardiac dimensions to their corresponding ACs can lead to important errors in size estimations of cardiac structure. CONCLUSIONS: The ACs found in this study are somewhat different from the corresponding isometric coefficients and often different from 1. This finding should be considered when normalizing cardiac structures to body size when making clinical decisions.
