CONSTRUYENDO LA MEMORIA COLECTIVA DEL PRIMER FRANQUISMO: BERENÀVEU A LES FOSQUES, DE JOSEP MARIA BENET I JORNET
Authors: Arroyo-Rodríguez Daniel 
Published: December 2022

In 1973 Josep Maria Benet i Jornet reconstructs the collective memory of the Spanish postwar during Francisco Franco’s dictatorship in his theater play Berenàveu a les fosques (You Were Having Tea in the Dark). This play initially clashes with the apathy of a public and critical environment that are not ready to confront this period, which causes it to be pushed to the sidelines of cultural discourse. The progress made in the recuperation of the historical memory during the last few years invites us to reevaluate Berenàveu as a valuable and innovative play that appeals to the individual memory of readers and spectators in order to construct a social memory of the Spanish postwar. Benet’s play revises 1950s Spanish realism to react against the oblivion of a period of misery and repression on which Franco’s regime supposedly builds a consumer welfare society during the second half of the dictatorship.
Resumen
En 1973 Josep Maria Benet i Jornet estrena la obra de teatro Berenàveu a les fosques (Merendabais a oscuras), en la que, de forma pionera, reconstruye la memoria de la posguerra durante la dictadura de Francisco Franco. Berenàveu contrasta inicialmente con la apatía de un público y de una crítica aún no preparados para hacer cuentas con este periodo, lo que relega esta obra al cajón de los trastos rotos del discurso cultural. No obstante, recientes avances en la recuperación de la memoria histórica invitan a reevaluar Berenàveu como una propuesta valiosa e innovativa que apela a la memoria individual de lectores y espectadores a la hora de reconstruir una memoria social de la posguerra. Para ello, esta obra recurre al realismo de los años cincuenta, reaccionando frente a un olvido que se fragua durante la propia dictadura y desde el que se dan por superados un pasado de represión y miseria sobre el que supuestamente se erige la sociedad de bienestar tardofranquista.
“ERAN DOS FLORES”: LAS PARADOJAS Y LAS AMBIVALENCIAS DE LA MATERNIDAD EN LA PLAZA DEL DIAMANTE
Authors: Gedo Gabrielle 
Published: December 2022

This paper examines the ambivalent and paradoxical feelings about motherhood in Catalonian author Mercè Rodoreda’s La plaza del Diamante, a stream-of-consciousness novel about a woman in Barcelona before and after the Spanish Civil War. Employing sociological, psychoanalytic, and feminist theories of gender and motherhood developed by authors such as Adrienne Rich, Jacqueline Rose, and Nancy Chodorow, motherhood is defined as not only a possible phase in a woman’s life but also a social institution with its own expectations and pressures. Viewed through this lens, motherhood is a complex, often ambivalent project. Motherhood itself is a bittersweet venture, where the positive comes from each mother creating her own individual experience and relationships outside of the pressures of the social institution of motherhood.
Resumen:
Este trabajo examina los sentimientos ambivalentes y paradójicos hacia la maternidad en La plaza del Diamante, una novela de flujo de conciencia escrita por la autora catalana Mercè Rodoreda, sobre una mujer en Barcelona antes y después de la Guerra Civil. Empleando las teorías sociológicas, psicoanalíticas y feministas del género y la maternidad desarrolladas por escritoras como Adrienne Rich, Jacqueline Rose y Nancy Chodorow, la maternidad es definida no solo como una etapa posible en la vida de una mujer, sino también como una institución social que conlleva sus propias expectativas. Desde esta perspectiva, la maternidad en la novela es un proyecto complejo y, muchas veces, ambivalente. La maternidad es algo agridulce y lo positivo solo surge cuando la madre crea su propia experiencia y sus propias relaciones individuales fuera de las expectativas de la institución social de la maternidad.

Age of Auto Electric
Authors: Eisler Matthew N. 
Published: December 2022

The electric vehicle revival reflects negotiations between public policy, which promotes clean, fuel-efficient vehicles, and the auto industry, which promotes high-performance vehicles.
Electric cars were once as numerous as internal combustion engine cars before all but vanishing from American roads around World War I. Now, we are in the midst of an electric vehicle revival, and the goal for a sustainable car seems to be within reach. In Age of Auto Electric, Matthew N. Eisler shows that the halting development of the electric car in the intervening decades was a consequence of tensions between environmental, energy, and economic policy imperatives that informed a protracted reappraisal of the automobile system. These factors drove the electric vehicle revival, argues Eisler, hastening automaking's transformation into a science-based industry in the process.
Challenging the common assumption that the electric vehicle revival is due to the development of better batteries, Age of Auto Electric instead focuses on changing environmental and socioeconomic conditions, energy and environmental policies, systems of energy conversion and industrial production, and innovation practices that affected the prevalence and popularity of electric vehicles in recent decades. Eisler describes a world in transition from legacy to alternative energy-conversion systems and the promises, compromises, new problems, and unintended consequences that enterprise has entailed.
Frequency selective reconfigurable microstrip antenna for cognitive radio applications
Authors: Aldar D. S. 
Published: December 2022

For the efficient utilization of electromagnetic radio spectrum cognitive radio communication system is employed, which deals with the spectrum scarcity. An efficient antenna is essential for the appropriate selection of the available frequencies. This paper presents the design and implementation of frequency reconfigurable antenna for cognitive radio applications. Reconfigurable inverted U-shape microstrip patch antenna feeding by 50 W microstrip line is designed and implemented. The designed and implemented antenna applied for switching frequency between 3.25 GHz to 4.1 GHz by choosing a specific sub-band from the specified wideband. The frequency reconfiguration was achieved by using twelve PIN diode switches by placing them on the slotted ground plane of the antenna. The PIN diodes were organized in such a way as to alter antenna bandwidth and to shift the operating band. The switching of PIN diodes controlled using the microcontroller to select the appropriate frequency. The performance of the simulated and fabricated antenna is investigated using different parameters.

ImportancePatients with COVID-19 have a high prevalence of diabetes, and diabetes and blood glucose control are determinants of intensive care unit admission and mortality.ObjectiveTo evaluate the association between COVID-19–related adverse outcomes and 8 antihyperglycemic drugs in patients with diabetes who were subsequently diagnosed and hospitalized with COVID-19.Data SourcesData were retrieved and collected in PubMed, Embase, Cochrane Central Register, Web of Science, and ClinicalTrials.gov from database inception to September 5, 2022.Study SelectionFor this systematic review and network meta-analysis, randomized clinical trials and observational studies conducted among patients with diabetes while receiving glucose-lowering therapies for at least 14 days before the confirmation of COVID-19 infection were included after blinded review by 2 independent reviewers and consultations of disagreement by a third independent reviewer. Of 1802 studies initially identified, 31 observational studies met the criteria for further analysis.Data Extraction and SynthesisThis study follows the Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting guideline. Bayesian network meta-analyses were performed with random effects.Main Outcomes and MeasuresA composite adverse outcome, including the need for intensive care unit admission, invasive and noninvasive mechanical ventilation, or in-hospital death.ResultsThirty-one distinct observational studies (3 689 010 patients with diabetes hospitalized for COVID-19) were included. The sodium-glucose cotransporter-2 inhibitors (SGLT-2is) were associated with relatively lower risks of adverse outcomes compared with insulin (log of odds ratio [logOR], 0.91; 95% credible interval [CrI], 0.57-1.26), dipeptidyl peptidase-4 inhibitors (logOR, 0.61; 95% CrI, 0.28-0.93), secretagogues (logOR, 0.37; 95% CrI, 0.02-0.72), and glucosidase inhibitors (logOR, 0.50; 95% CrI, 0.00-1.01). Based on the surface under the cumulative ranking curves value, SGLT-2is were associated with the lowest probability for adverse outcomes (6%), followed by glucagon-like peptide-1 receptor agonists (25%) and metformin (28%). A sensitivity analysis revealed that the study was reliable.Conclusions and RelevanceThese findings suggest that the use of an SGLT-2i before COVID-19 infection is associated with lower COVID-19–related adverse outcomes. In addition to SGLT-2is, glucagon-like peptide-1 receptor agonists and metformin were also associated with relatively low risk of adverse outcomes.

AbstractLaser‐fabrication of graphene from cellulose‐based feedstock materials often requires extensive preprocessing. This work demonstrates laser fabrication of porous, 3D graphene from a new class of marine‐based sustainable materials–chitosan biopolymers. The biopolymer films contain only chitosan, acetic acid, glycerol, and water. Fourier transform infrared spectroscopy studies indicate that the cured chitosan films still retain a significant water content (≈30%), enabling production of flexible films. A simple 3‐step laser fabrication process is presented using low‐cost infrared (CO2, 2.1 W) and visible (405 nm, 0.5 W) hobbyist laser engravers, with measured sheet resistance values as low as 40 ohms sq.−1. Transient electrochemical detection of an inner sphere redox molecule is demonstrated using a graphene‐like carbon working electrode fabricated on a water‐soluble chitosan substrate.

Published: December 2022

AbstractDevelopment of chromium‐doped luminescent materials is pertinent to many emerging applications, ranging from agriculture, food industry to noninvasive health monitoring. The fundamental importance of chromium‐activated luminescent materials in the field of optics and biomedicine makes the rapid development of novel materials and relevant applications. Herein, the recent advances on the luminescence principle and photoluminescence (PL) optimization for Cr3+‐activated luminescent materials together with their potential applications are reviewed. The different types of most recently developed Cr3+‐doped luminescent materials and the design principles are systematically summarized. The associations between crystal structure and near‐infrared (NIR) PL properties, as well as performance‐evaluating parameters are introduced with the examples of known NIR emitting phosphors, which will be helpful to explore future NIR luminescent materials. Based on crystal field control, site engineering, and electron–phonon coupling, several efficient strategies for optimizing luminescence performances including bandwidth, thermal stability, and quantum efficiency of Cr3+‐doped NIR luminescent materials are proposed. Then, potential applications in the fields of food analysis, night vision, information encryption, and optical sensors are surveyed. Finally, the challenges of promising Cr3+‐doped luminescent materials are proposed.

Published: December 2022

AbstractDesigning highly active and durable electrocatalysts remain an ongoing challenge in the oxygen reduction reaction (ORR). Here, the reductive IL/Ti3C2Tx(FA) is produced in a water‐free mixture of formic acid (FA), ionic liquid (IL) and LiF, subsequently, the simultaneous reduction encapsulation trap the Pd nanocatalysts and IL within bilayer carbide‐derived carbon (CDC) to obtain Pd@IL/CDC(FA) with high metal loading up to 69.7%. Thereby, the featured active phases in Pd@IL/CDC(FA) impart potent chemical nanoconfinement to defend metals from dissolution and aggregation, boost mass and electron transfer, and mediate oxidation states and adsorption/desorption of metal Pd in the ORR. Instead of deactivation and Ostwald ripening, the catalytic performances of Pd@IL/CDC(FA) are gradually enhanced in an accelerated durability test up to 20 000 cycles. In a Zn–air battery, the Pd@IL/CDC(FA) cathode gives a specific capacity of 812.6 mAh gZn−1 and a voltage loss of only 41 mV in galvanostatic discharge for 1000 h. The work opens new venues in controllably preparing high activity and durable electrocatalysts from in‐situ generated CDCs.

Published: December 2022

AbstractElectrochemical synthesis in chemical biology is a milder, biocompatible, and environmentally friendly process for constructing novel types of bioconjugated systems. Herein, we report on the development of an indirect electrochemical strategy that allows a trifluoromethyl group to be incorporated into a tryptophan residue. This protocol allowed fluorinated peptides to be produced, thus allowing their characterization by 19F‐NMR. Interestingly, the trifluoromethylation of tryptophan did not appear under conditions of direct electrolysis; instead, as we introduced ferrocene as a mediator to allow indirect electrosynthesis, the desired product could be obtained in 67% isolated yield. Furthermore, various oligopeptides are successfully coupled to the Trp residue selectively. Mechanistic studies involving CV and DFT calculations indicated that the transformation proceeds through the homo‐cleavage of CF3SO2Na via ferrocene‐mediated indirect electrolysis. Subsequently, the addition of a CF3 radical allowed the labelled Trp to be incorporated into the corresponding products. This electrochemical protocol provides a new toolkit for the trifluoromethylation of peptides that contain tryptophan.

Published: December 2022

AbstractCharge compensation on anionic redox reaction (ARR) has been promising to realize extra capacity beyond transition metal redox in battery cathodes. The practical development of ARR capacity has been hindered by high‐valence oxygen instability, particularly at cathode surfaces. However, the direct probe of surface oxygen behavior has been challenging. Here, the electronic states of surface oxygen are investigated by combining mapping of resonant Auger electronic spectroscopy (mRAS) and ambient pressure X‐ray photoelectron spectroscopy (APXPS) on a model LiCoO2 cathode. The mRAS verified that no high‐valence oxygen can sustain at cathode surfaces, while APXPS proves that cathode electrolyte interphase (CEI) layer evolves and oxidizes upon oxygen gas contact. This work provides valuable insights into the high‐valence oxygen degradation mode across the interface. Oxygen stabilization from surface architecture is proven a prerequisite to the practical development of ARR active cathodes.

Published: December 2022

AbstractDeveloping chemical tools to detect and influence biological processes is a cornerstone of chemical biology. Here we combine two tools which rely on orthogonality– perfluorocarbons and multiplexed shortwave infrared (SWIR) fluorescence imaging– to visualize nanoemulsions in real time in living mice. Drawing inspiration from fluorous and SWIR fluorophore development, we prepared two SWIR‐emissive, fluorous‐soluble chromenylium polymethine dyes. These are the most red‐shifted fluorous fluorophores– “fluorofluorophores”—to date. After characterizing the dyes, their utility was demonstrated by tracking perfluorocarbon nanoemulsion biodistribution in vivo. Using an excitation‐multiplexed approach to image two variables simultaneously, we gained insight into the importance of size and surfactant identity on biodistribution.
Boosting Charge Transport in a 2D/3D Perovskite Heterostructure by Selecting an Ordered 2D Perovskite as the Passivator

Published: December 2022

AbstractWe demonstrate that an ordered 2D perovskite can significantly boost the photoelectric performance of 2D/3D perovskite heterostructures. Using selective fluorination of phenyl‐ethyl ammonium (PEA) lead iodide to passivate 3D FA0.8Cs0.2PbI3, we find that the 2D/3D perovskite heterostructures passivated by a higher ordered 2D perovskite have lower Urbach energy, yielding a remarkable increase in photoluminescence (PL) intensity, PL lifetime, charge‐carrier mobilities (ϕμ), and carrier diffusion length (LD) for a certain 2D perovskite content. High performance with an ultralong PL lifetime of ≈1.3 μs, high ϕμ of ≈18.56 cm2 V−1 s−1, and long LD of ≈7.85 μm is achieved in the 2D/3D films when passivated by 16.67 % para‐fluoro‐PEA2PbI4. This carrier diffusion length is comparable to that of some perovskite single crystals (>5 μm). These findings provide key missing information on how the organic cations of 2D perovskites influence the performance of 2D/3D perovskite heterostructures.
Optimal standby activation in m‐out‐of‐n systems: A preventive approach

AbstractThis article investigates an optimal preventive standby activation policy for an ‐out‐of‐ redundant system. We assume that for such a system, which starts operating at time , a standby component will be activated at either the failure time of the system or at a predetermined time , whichever occurs first. We first obtain the system reliability function under this switching policy as a function of . Then, we investigate the optimal switching time so that the mean time to failure of the system is maximized. The results indicate that the existence of an optimal value of depends on the lifetime of the standby redundancy and its virtual age in the standby state. Some illustrative examples are presented to examine the theoretical outcomes.
Eco‐economic optimal sizing and operation of PV‐battery systems in buildings – The Role of CO2 price signals
Authors: Maier Laura , Ellinger Matthias , Hering Dominik , Müller Dirk 
Published: December 2022

AbstractCO2 pricing enables building owners to benefit from reduced emissions. Changing power plant mix leads to dynamic CO2 factors and price signals that PV‐battery systems can exploit. The system's size and CO2 prices influence profitability. So far, no study exists assessing CO2 pricing's influence on PV‐battery systemś optimal sizing and operation. We, therefore, investigate the interaction of PV‐battery sizing and operation with CO2 pricing and combine Design of Experiments with model predictive control. For a CO2 price of 100 €/t, the cost‐optimal design decreases emissions by 79.7 %. Furthermore, high CO2 prices yield large PV and medium battery sizing. The results prove that CO2 pricing is a valuable instrument to encourage CO2‐reducing investments of building owners. We recommend future studies to include the effect of CO2 pricing on the power plant mix and thus the CO2 factor. We assume a change in the merit order due to a shift in marginal costs of the respective power plants.
Regelungsbedarf und Ansätze einer Rückbaurichtlinie für Brückenbauwerke
Authors: Krill Alfred , Lingemann Jan , Schacht Gregor 
Published: December 2022

AbstractWährend in der Vergangenheit im Zuge des Aufbaus des Brückennetzes in Deutschland die Normung des Neubaus immer weiterentwickelt wurde, befindet sich die Entwicklung des Rückbaus noch in den Anfängen. Wegen des zunehmenden Alters von Bestandsbrücken und der veränderten Nutzungsanforderungen werden heute meist Ersatzneubauten erforderlich. Der Rückbau der Bestandsbrücken erfolgt nach wie vor ohne speziell hierfür abgestimmtes Regelwerk. Die beteiligten Bauherren, Planer und Ausführende gehen dabei Risiken ein, die es in Zukunft zu verringern gilt. Nachdem in vielen Tagungen und Gesprächen Regelungen zum Rückbau gefordert wurden, ist nun aus den Erfahrungen beim Entwurf, der Ausführungsstatik und der statisch‐konstruktiven Prüfung beim Rückbau ein bislang unveröffentlichter erster Entwurf zur Regelung des Rückbaus von Brücken entstanden, dessen Inhalt und Bearbeitungsstand hier wiedergegeben ist.
