Published: June 2024

ABSTRACTTheories of adolescent development suggest that elevated neural sensitivity to social evaluation confers tradeoffs for adolescents’ wellbeing, promoting adaptation to changing social contexts but increasing risk for emotional distress and depression. This study investigated whether the association between neural processing of peer feedback and depressive symptoms depends on teacher‐reported executive function (EF) ability in adolescent girls. Girls showed activation to negative and positive peer feedback in regions implicated in social–emotional processing that interacted with EF to predict depressive symptoms. Specifically, activation predicted more depression in youth with poorer EF but less depression in youth with better EF, suggesting that the impact of increased social sensitivity may depend on youths’ ability to regulate this sensitivity in adaptive ways.

Published: June 2024

AbstractIn the intricate web of plant–animal interactions, granivore birds can play a dual antagonist–mutualist role as seed predators and dispersers. This study delves into the ecological significance of the house sparrow (Passer domesticus) as seed disperser by endozoochory. A sample of individual droppings and faecal pools were collected from a communal roost in central Spain to examine the presence of seeds. Seed viability was determined using the tetrazolium test. Our findings revealed that around 22% of the analysed droppings contained seeds, contradicting the prevalent notion of house sparrow solely as seed predator. Viability tests demonstrated that 53.9% of the defecated seeds were viable, although it varied between plant species, including those from fleshy‐fruited common fig and five species of dry‐fruited herbs. This study challenges the traditional perspectives on the ecological role of the house sparrow, and glimpses on their contribution to seed dispersal. Understanding the nuanced roles of granivore species like the house sparrow is crucial for developing holistic conservation and management strategies in urban and agricultural landscapes. Future studies are encouraged to unravel the actual role of this cosmopolitan species as disperser of a likely broad spectrum of wild, cultivated and exotic plants.
Earthquake economic loss assessment of existing concrete shear wall residential buildings in Eastern Canada
Authors: Montazeri Maryam , Abo El Ezz Ahmad 
Published: June 2024

AbstractPast major earthquakes have demonstrated that a significant proportion of existing residential buildings are vulnerable to seismic hazards, resulting in economic and social losses. The assessment of earthquake‐induced losses is crucial for devising strategies aimed at enhancing seismic resilience through mitigation plans and emergency response measures. This study intends to provide an analytical methodology for evaluating economic losses for existing residential concrete shear wall buildings in Eastern Canada seismic zones based on Canadian‐compatible seismic capacity parameters. A sampled data set related to residential buildings in Montreal was analyzed and statistical distributions were developed that represent the proportion of buildings in different seismic design code levels and number of stories. Vulnerability analyses were performed, which involved estimating buildings' response under seismic hazard inputs according to the 2020 National Building Code of Canada and conducting loss assessment for structural components, nonstructural displacement‐sensitive components, nonstructural acceleration‐sensitive components, and contents. The results of vulnerability analyses in terms of loss ratio curves showed that the seismic performance varies between mid‐rise and high‐rise concrete shear wall buildings with different seismic design code levels, and nonstructural displacement‐sensitive components exerted the most significant influence on overall economic losses among building components. In addition, a comparison was conducted between Canadian‐compatible economic loss ratio curves and those developed based on the standard seismic capacity parameters in the Hazus technical manual and differences in predicted loss ratios were discussed. The developed loss ratio curves can be integrated into regional scale loss assessment tools for rapid estimation of earthquake‐induced economic losses for concrete shear wall buildings as a function of seismic intensity.

Published: June 2024

AbstractThe search for chemical indicators of life is a fundamental component of potential future spaceflight missions to ocean worlds. Capillary electrophoresis (CE) is a useful separation method for the determination of the small organic molecules, such as amino acids and nucleobases, that could be used to help determine whether or not life is present in a sample collected during such missions. CE is under development for spaceflight applications using multiple detection systems, such as laser induced fluorescence (LIF) and mass spectrometry (MS). Here we report CE‐based methods for separation and detection of major polar metabolites in cells, such as amino acids, nucleobases/sides, and oxidized and reduced glutathione using detectors that are less expensive alternatives to LIF and MS. Direct UV detection, indirect UV detection, and capacitvely coupled contactless conductivity detection (C4D) were tested with CE, and a combination of direct UV and C4D allowed the detection of the widest variety of metabolites. The optimized method was used to profile metabolites found in samples of Escherichia coli and Pseudoalteromonas haloplanktis and showed distinct differences between the species.
Directing the photogenerated charge flow in a photocathodic metal protection system with single‐domain ferroelectric PbTiO3 nanoplates

Published: June 2024

AbstractPhotocathodic protection (PCP) is arguably an ideal alternative technology to the conventional electrochemical cathodic protection methods for corrosion mitigation of metallic infrastructure due to its eco‐friendliness and low‐energy‐consumption, but the construction of highly‐efficient PCP systems still remains challenging, caused primarily by the lack of driving force to guide the charge flow through the whole PCP photoanodes. Here, we tackle this key issue by equipping the PCP photoanode with ferroelectric single‐domain PbTiO3 nanoplates, which can form a directional “macroscopic electric field” throughout the entire photoanode controllable by external polarization. The properly poled PCP photoanode allows the photogenerated electrons and holes to migrate in opposite directions, that is, electrons to the protected metal and holes to the photoanode/electrolyte interface, leading to largely suppressed charge annihilation and consequently a considerable boost in the overall solar energy conversion efficiency of the PCP system. The as‐fabricated photoanode can not only supply sufficient photocurrent to 304 stainless steel to initiate cathodic protection, but also shift the metal potential to the corrosion‐free range. Our findings provide a viable design strategy for future high‐performance PCP systems based on ferroelectric nanomaterials with enhanced charge flow manipulation.

Published: June 2024

AbstractThe increasing installment of solar and wind renewable energy systems create a volatile energy demand to be met by electricity providers. A nuclear hybrid energy system is a nuclear reactor with energy storage that integrates into the grid with renewable energy sources. The Natrium design by TerraPower and GE Hitachi is a sodium fast reactor with molten salt energy storage. The Natrium design operates at steady state of 345 MWe and can boost up to 500 MWe for 5.5 hours. This study uses Dymola and the Modelica language to model the Natrium‐based nuclear‐renewable hybrid energy system. The dynamic system model is tested using hourly historical data from the state of Texas 2021 to show how renewables affect the electricity demand and how energy storage affects the Natrium system response to the demand. According to the results, while the available storage will allow the Natrium design to boost electricity production when the demand and electricity price is high making it more economically viable, the current molten salt storage is slightly undersized for the ERCOT market.
A novel battery management scheme for critical loads
Authors: Bandatmakuru Lakshmi Sravan , Sandepudi Srinivasa Rao 
Published: June 2024

AbstractThis article proposes a novel battery management system (BMS) to ensure uninterruptible power delivery to a 48 V DC bus used for electric vehicle charging stations, data centers, telecommunication systems, and critical care units such as hospitals. The proposed BMS facilitates constant current and constant voltage charging to maintain optimal battery performance during normal operation. This BMS is designed for effective control, monitoring and protection of two lead‐acid battery units to form battery energy storage system (BESS). Furthermore, it is capable of isolating batteries in abnormal conditions and operates them independently to provide reliable supply at output terminals with full capacity. The system utilizes a 30 V DC source derived from AC mains or solar photovoltaic system. This supply is used to charge the BESS and also supply to the load. In the event of failure of 30 V supply, it seamlessly transits to BESS mode to supply power to boost converter to maintain constant 48 V DC output at load terminal. The proposed system architecture not only enhances power reliability but also improves overall system efficiency, making it well‐suited for critical applications require continuous and stable power supply. Simulation studies using Matlab/Simulink and analytical results using TINA (Tool kit for Interactive Network Analysis) are presented to show that 48 V DC supply is maintained at output terminals during failure of input 30 V DC source or failure of one battery unit.

Published: June 2024

AbstractSilver nanoclusters (AgNCs) have shown broad application prospects in catalysis, sensing, and biological fields. However, the limited stability of AgNCs has become the main challenge restricting their practical application in complex environments. Herein, a mussel‐inspired, dopamine‐assisted self‐assembly approach is reported to fabricate 3D AgNC aerogels (PDA/AgNCs), which possess significantly enhanced structural stability and synergistic functional properties. The prepared AgNC aerogels display a hierarchical network structure with an ultrafine ligament size of 10.3 ± 1.2 nm and a high specific surface area of 50.7 m2 g−1. The gelation mechanism is elucidated by in‐depth characterization and time‐lapse monitoring of the gelation process vis spectroscopic and microscopic approaches. Owing to the distinct features of aerogels and the synergistic effect of AgNCs and PDA, the fabricated aerogels can not only efficiently decolorize dyes with a faster kinetic than individual AgNCs, but also exhibit remarkable broad‐spectrum antimicrobial activity. Consequently, a conceptual water‐treatment device is established by depositing PDA/AgNC aerogels on the cotton substrate, which shows good performance in both catalytic dye degradation and bacterial killing in the flowing system. This mussel‐inspired self‐assembly strategy has great potential in developing robust AgNC‐based functional materials, which also provides a new guideline for designing sophisticated materials with integrated functions and synergistic properties.

Published: June 2024

ABSTRACTIn a proton exchange membrane fuel cell (FC), the gas diffusion layer (GDL) is identified as the component that is most affected by mechanical compression. In this article, a particular focus is provided on the methods to measure the three main electrical parameters—contact resistance, through‐plane resistance, and in‐plane resistance—of the GDL under compression. A nonlinear decrease of these resistances under compression is typically observed. In particular, an important decrease is observed from 0 to 2 MPa, then a lower one above 2 MPa. The smallest contact and in‐plane resistances are measured for the graphitized straight carbon papers analyzing GDL resistances under compression gives a first approach to explaining ohmic losses in FCs as a large part of these losses is related to the GDL. This review would be helpful for researchers in better understanding ohmic losses and establishing a database of main GDL electrical resistances and their variations according to several operating parameters. These data could be used in design models to optimize GDL properties.

ABSTRACTUsing microbial fuel cells (MFCs) as biosensors ensures a sustainable method for water quality detection. However, the research on MFC‐based biosensors with a tubular setup is still scarce. In this study, a tubular multi‐array MFC‐based biosensor setup with air‐cathodes was assembled under the membrane electrode assembly configuration. Three different materials, including carbon black (CB), Pt/C (PtC), and polyaniline (PANI), were synthesized and coated on the membrane‐facing side of the air‐cathode to demonstrate the effects of modified air‐cathodes on the overall performance of the MFC‐biosensors. Unmodified carbon cloths were used as anodes. Three days of startup period were required by the biosensors before producing an electrical signal output. The highest current density was obtained by the polytetrafluoroethylene (PTFE)/CB/PtC (0.31 A m−2) sample followed by PTFE/CB/PANI (0.09 A m−2), and lastly PTFE/CB (0.05 A m−2). The control (PTFE only) sample did not generate any noticeable electrical signal. The electrochemical impedance spectroscopy analysis showed that the incorporation of PtC on the PTFE/CB sample lowered the charge transfer resistance (Rct), whereas the addition of PANI increased the Rct. Despite the differences in Rct values, both PTFE/CB/PtC and PTFE/CB/PANI samples demonstrated a better current density production than the PTFE/CB sample. Thus, modified air‐cathodes further elevated the biosensor's performance.

ABSTRACTThis study investigates the novel cobalt‐free high‐entropy perovskite, La0.2Pr0.2Nd0.2Sm0.2Sr0.2FeO3–δ (LPNSSF), as an air electrode material for solid oxide cells (SOCs). When testing a button cell with a single‐phase LPNSSF electrode, a current density of 0.55 A cm−2 is obtained at 0.7 V in fuel cell mode at 800°C. In order to mitigate the moderate electronic conductivity of LPNSSF, two approaches are explored. Incorporating a Co‐free highly conductive perovskite, LaNi0.6Fe0.4O3–δ (LNF), either as an LPNSSF–LNF composite electrode or as a current collector layer (CCL), enhances the performance to 0.61 and 0.66 A cm−2, respectively, under the same conditions. Microstructural features are studied by electron microscopy and show a rather dense structure of the CCL. Optimization of the current collector increases the current density further to 0.96 A cm−2 at 0.7 V in a 5 × 5 cm2 anode‐supported cell at 800°C. This cell exhibits good long‐term stability in electrolysis mode in H2‐H2O with 80% humidification. Continuous polarization of −0.69 A cm−2 is sustained for 1000 h, with an average degradation rate of 10 mV kh−1 after an initial run‐in phase. These findings demonstrate the promising performance and durability of LPNSSF as cobalt‐free SOC air electrode.

AbstractPerinatal white matter injury (WMI) is the leading cause of long‐term neurological morbidity in infants born preterm. Neuroinflammation during a critical window of early brain development plays a key role in WMI disease pathogenesis. The mechanisms linking inflammation with the long‐term myelination failure that characterizes WMI, however, remain unknown. Here, we investigate the role of astrocyte reactivity in WMI. In an experimental mouse model of WMI, we demonstrate that WMI disease outcomes are improved in mutant mice lacking secretion of inflammatory molecules TNF‐α, IL‐1α, and C1q known, in addition to other roles, to induce the formation of a neuroinflammatory reactive astrocyte substate. We show that astrocytes express molecular signatures of the neuroinflammatory reactive astrocyte substate in both our WMI mouse model and human tissue affected by WMI, and that this gene expression pattern is dampened in injured mutant mice. Our data provide evidence that a neuroinflammatory reactive astrocyte substate correlates with adverse WMI disease outcomes, thus highlighting the need for further investigation of these cells as potential causal players in WMI pathology.
Longitudinal associations of loneliness and social isolation with care dependence among older adults in Latin America and China: A 10/66 dementia research group population‐based cohort study

Published: June 2024

AbstractObjectivesWith increasing life expectancy and rapid ageing, there is an expanding number of older people who have functional declines, greater needs for care and support and who are at increased risk of insufficient social interaction. Longitudinal investigations on the interplay between loneliness, social isolation and care dependence remain limited. This study thus aimed to investigate the longitudinal reciprocal association between social isolation/loneliness and care dependence among older adults in Latin America and China.MethodsWe analysed data from the population‐based cohorts from the 10/66 Dementia Research Group (DRG) project (baseline 2003‐07 and follow‐up 2007–2010). The 10/66 DRG study recruited and followed up older adults aged 65 years or above in 11 catchment areas in Latin America and China. A total of 15,027 older adults from Latin America and China (mean age = 73.5, standard deviation = 6.5) were included in our analyses. Cross‐lagged panel models were used to investigate potential reciprocal associations.ResultsLoneliness was positively associated with care dependence at baseline (β = 0.11, p < 0.001 in Latin America; β = 0.16, p < 0.05 in China]. Social isolation consistently had a stronger positive association with care dependence across all study sites in both waves. Longitudinally, care dependence positively predicted loneliness (β = 0.10, p < 0.001) and social isolation (β = 0.05, p < 0.001) in Latin American study sites but not in China. Yet there was no statistical evidence of lagged effects of loneliness and social isolation on care dependence in all study countries.ConclusionsOlder people with care dependence are at risk of developing loneliness and social isolation. It is crucial to develop complex care models using a societal approach to address social and care needs holistically, especially for the older group with declining functional capacity. Future longitudinal research is required to explore the causal mechanisms of relationships and cultural differences, in order to inform the development of culturally appropriate care models.

AbstractBackgroundCorticosteroid therapy is commonly recommended for acute facial nerve weakness; however, its effectiveness in treating traumatic nerve injuries remains controversial. This study investigated the functional recovery and cellular effects of systemic dexamethasone administration after facial nerve injury.MethodsC57BL/6 mice were assigned to two groups by intraperitoneal injection: the phosphate‐buffered saline group and the dexamethasone group. Facial nerve crush injury was induced, followed by the functional grading of recovery. Cellular effects were investigated using transmission electron microscopy, flow cytometry, immunofluorescence, and intravital imaging.ResultsMacrophage infiltration into the facial nerves was significantly inhibited by systemic dexamethasone administration. However, dexamethasone group slightly delayed the functional recovery of the facial nerve compared to the PBS group. In addition, the morphological changes in the nerve were not significantly different between the two groups at 14 days post‐injury. Macrophage migration analysis in the intravital imaging also showed no difference between groups.ConclusionsIn summary, systemic dexamethasone successfully inhibited leukocyte infiltration; however, functional recovery was delayed compared to the PBS control group. Clinically, these findings indicate that more evidence and research are required to use steroid pulse therapy for the treatment of traumatic facial nerve injuries.
