Acoustic methods for Gelidium seaweed detection

Se han realizado mediciones del coeficiente de reflexión y absorción de una capa espesa de algas de Gelidium sesquipedale (Clem. Born. et Thur.), sobre un fondo de arena, dispuesto en un tanque de experiencias hidroacústicas. Como resultado de la reducida sección transversal acústica de cada brote del alga, y de su alto contenido de agua, su impedancia acústica tiene un valor muy próximo a la impedancia acústica del agua marina y, en consecuencia, el nivel de blanco de cada brote es muy débil. El rango de frecuencias utilizado parte de 100 kHz, alcanzando 500 kHz. El valor promedio del nivel de difusión de fondo de la capa de alga de Gelidium encontrado varía entre -26 dB y -34 dB en el rango de frecuencias utilizado.The reflection and absorption coefficients of a thick layer of Gelidium sesquipedale (Clem. Born. et Thur.) seaweed covering a sandy bottom were determined in a laboratory tank. As a result of the reduced vertical cross-section and the high water content of this seaweed, its acoustical impedance is very similar to water impedance, and the target strength of each individual seaweed frond is very weak. The usual frequency range for detection of marine life, 100-500 kHz, has been used. The average value of the bottom scattering strength was found to be between -26 dB and -34 dB in the frequency band used.Instituto Español de Oceanografí

Emerging Ionic Soft Materials based on Deep Eutectic Solvents

PostprintIn the last five years, the use of deep eutectic solvents (DES) have been opening new perspectives towards the creation of novel ionic soft materials as alternatives to expensive ionic liquids. This Mini-Review highlights the progress and advances in soft ionic materials or gels, mostly composed by a DES immobilized within difference matrices, such as linear polymers, polymer networks, biopolymers, supramolecular compounds or organosilane networks. By taking advantage of the DES characteristics and properties in the solid state, this building system delivers a variety of tailor-made materials showing different functionalities (ionic conductivity, self-healing, stretchability and pH-responsiveness) and offers a way to circumvent drawbacks related to shaping and risk of leakage in many technological applications. In this context, we provide a judicious analysis of these emerging ionic soft materials, their properties and applications open in energy, (bio)electronics, drug delivery, analytical chemistry, and wastewater treatment. Perspectives and opportunities for future research directions on this blossoming field are also discussed.Liliana C.

The primitive model of ionic fluids near its critical point in the Poisson–Boltzmann and modified Poisson–Boltzmann theories

The Poisson–Boltzmann (PB) and modified Poisson–Boltzmann (MPB) theories are used to investigate the primitive model of ionic fluids in the low density–large coupling regime where the liquid–vapor transition is situated. The PB and MPB spinodal curves for the restricted primitive model are calculated from the virial route and compared with those from the mean spherical approximation (energy route) and the hybrid hypernetted‐chain/mean spherical approximation (virial route). The effect of unequal ion sizes on the critical point and spinodal curves is also considered.National Sanitation Foundation (NSF) EE.UU.

Los carnívoros del yacimiento pleistoceno de Cueva del Búho (Segovia, España) y sus huellas de actividad

This paper deals with the carnivores from Cueva del Búho (Segovia, Spain) identifying five species (Croeuta eroeuta spelaea, Meles meles, Canis lupus, Vulpes vulpes and, Lynx spelaea). Living traces of hyena are decribed: coprolites, bone surface modifications and body parts representation. It is deduced that this site has been originated in a den of Croeuta croeuta spelaea.Este trabajo estudia los carnívoros de Cueva del Búho (Segovia, España) identificando cinco especies (Croeuta croeuta spelaea, Meles meles, Canis lupus, Vulpes vulpes y Lynx spelaea).

Screening for the efficacy on lipid accumulation in 3T3-L1 cells is an effective tool for the identification of new anti-diabetic compounds

Reducing lipid accumulation in insulin target tissues is critical for the treatment of type 2 diabetes. This study aimed to develop a biochemical assay in cells for high throughput (HTP) screening of anti-diabetic drugs by reducing lipid accumulation via different mechanisms

An evaluation on the clinical outcome prediction of rotor detection in non-invasive phase maps

[EN] Phase maps obtained from Electrocardiographic imaging (ECGI) have been used in the past for rotor identification and ablation guidance in atrial fibrillation (AF). In this study, we propose a new rotor detection algorithm and evaluate its potential use for prediction of pulmonary vein isolation (PVI) success. The mean precision and recall of the algorithm were evaluated by using manually annotated ECGI phase maps and resulted in 0.82 and 0.75, respectively. Phase singularities and rotors were then quantified on ECGI signals from 29 patients prior to PVI. A significantly higher concentration of phase singularities (PSs) in the pulmonary veins in patients with a successful PVI was found. Our results suggest that rotorrelated metrics obtained from ECGI derived phase maps contain relevant information to predict clinical outcome in PVI patients.This work was supported by PersonalizeAF project.

Tailored CO2-philic Anionic Poly(ionic liquid) Composite Membranes: Synthesis, Characterization and Gas Transport Properties

Unformatted post printPolymeric membranes either containing, or built from, ionic liquids (ILs) are of great interest for enhanced CO2/light gas separation due to the stronger affinity of ILs toward quadrupolar CO2 molecules, and hence, high CO2 solubility selectivity. Herein, we report the development of a series of four novel anionic poly(IL)-IL composite membranes via a photopolymerization method for effective CO2 separation. Interestingly, these are the first examples of anionic poly(IL)-IL composite systems, in which the poly(IL) component has delocalized sulfonimide anions pendant from the polymer backbone with imidazolium cations as “free” counterions. Two types of photopolymerizable methacryloxy-based IL monomers (MILs) with highly delocalized anions (–SO2–N(-)–SO2–CF3 and –SO2–N(-)–SO2–C7H7) and mobile imidazolium ([C2mim]+) counter cations were successfully synthesized and photopolymerized with two distinct amounts of free IL containing the same structural cation ([C2mim][Tf2N]) and 20 wt% PEGDA crosslinker, to serve as a composite matrix. The structure-property relationships of the four newly developed anionic poly(IL)-IL composite membranes were extensively characterized by TGA, DSC, and XRD analysis. All of the newly developed anionic poly(IL)-IL composite membranes exhibited superior CO2/CH4 and CO2/N2 selectivities together with moderate CO2/H2 selectivity and reasonable CO2 permeabilities. The membrane with an optimal composition and polymer architecture (MIL-C7H7/PEGDA(20%)/IL(1eq.)) reaches the 2008 Robeson upper bound limit of CO2/CH4, due to the simultaneous improvement in permeability and selectivity (CO2 permeability ~ 20 barrer and αCO2/CH4 ~119). This study provides a promising strategy to explore the benefits of anionic poly(IL)-IL composites to separate CO2 from flue gas, natural gas, and syngas streams and open up new possibilities in the polymer membrane design with strong candidate materials for practical applications.Partial support for this work provided by the United States Department of Energy (DE-SC0020282) and NASA Marshall Space Flight Center (80NSSC19K1314), is gratefully acknowledged.
