Published: August 2022

AbstractAs an emerging and potential replacement system for liquid electrolytes, polymer electrolytes (PEs) exhibit unique capacity in suppressing metal dendrite formation and leakage risks. However, the most used polymer matrix, including polyether, polyester, and polysiloxane, still cannot meet the practical demands for metal electrode compatibility and long lifespan. In this study, gel polymer electrolytes consisting of a polyurea network with abundant hydrogen bonds and deep eutectic electrolyte (DEE) are designed and prepared in‐situ. The hydrogen bonding between polyurea chains and polyurea‐DEE provides good interfacial stability between PEs and lithium metal. As a result, the assembled Li/LiFePO4 cells based on this electrolyte deliver a long cycle life with 90 % retention after 500 cycles and 76.5 % retention after 1000 cycles at 1 C. In addition, the flexible design characteristics of polyurea structure permit easy operation for performance optimization by modulating the composition of hard and soft segments, and enhanced ionic conductivity and self‐healing efficiency are obtained. This study provides a novel method for preparing advanced polymer electrolytes for lithium metal batteries.
Exploring spatial nonstationarity for four mammal species reveals regional variation in environmental relationships
Authors: Pease Brent S. , Pacifici Krishna , Kays Roland 
Published: August 2022

AbstractBroad‐scale ecological research on species distributions commonly presumes that the correlative relationships discovered are stationary over space. This is an assumption of most species distribution models (SDMs) that combine observations of species occurrence with environmental characteristics to understand current ecological correlates and to predict distributions based on those relationships. However, ecological relationships may vary spatially because of changes in the environment (i.e., resource availability) or the organism itself (i.e., local adaptation). Discovering this within‐species variation typically requires dense datasets over large geographic areas, which are now being provided by the recent proliferation of open‐access biodiversity occurrence records. Using nearly 4000 sampling locations from an open‐access, state‐wide camera‐trapping project, we explore the space‐varying effects of covariates on the distribution of four mammal species at two scales: region‐specific and fine resolution, with the latter estimated using spatially varying coefficients (SVC) models, to understand the scale of spatial variation in ecological relationships. Among the four species tested, the ecological relationships for two were best explained with the regional models, equivocal results for one species, while the SVC model had superior fit and predictive performance for the final species (white‐tailed deer,Odocoileus virginianus). Spatial nonstationarity was more common in relationships with landscape composition characteristics, such as housing density, than in landscape configuration metrics, such as patch richness density. One of the most appealing results of an SVC approach is not only the improved predictions across large landscapes but also understanding how animals are responding to the environment differently at the management unit level. For example, we found that deer's spatially varying relationship with forest cover was best explained by an interactive effect of deer management units (i.e., differences in deer populations) and predator pressure. These findings lead to a new hypothesis about how deer may be differentially using forested environments across space and could be a promising area of future research. Given sufficient data, accounting for nonstationarity in SDMs can show large‐scale ecological patterns while also detecting local level changes in animal ecology in areas small enough that management or protection can be readily implemented.

Published: August 2022

AbstractOne of the challenges medicine faces is the constantly growing resistance of pathogens to various classes of antibiotics. In this study, we investigated the use of capillary electrophoresis (CE) to characterize and assess the physiological states of three clinical bacterial strains—methicillin‐resistant Staphylococcus aureus (MRSA) and methicillin‐sensitive S. aureus (MSSA), and Escherichia coli extended‐spectrum β‐lactamases (ESβL)—exposed to different antibiotics. All chosen bacteria are the leading causes of healthcare‐associated and hospital‐acquired invasive infections in adults. In the first part of the research, it was determined the optimal incubation time of the tested strains with antibiotics, represented as an optimal time of 24 h. In the second part, we have compared two approaches: flow cytometry (FC) as a standard method and CE as a proposed alternative approach. The viability of clinical strains treated with different class antibiotics calculated in CE measurements was strongly correlated (>0.83 for MSSA, >0.92 for ESβL and MRSA) with the viability obtained on the basis of FC measurements. As a result, CE has a chance to become a modern diagnostic method used in clinical practice. The CE cutoff was found to be 50%; above this value, the strain shows resistance to the action of the antibiotic.

Published: August 2022

AbstractElectrochemical CO2 reduction reaction is a promising protocol to achieve a carbon‐neutral cycle. Herein, we report a general strategy to regulate the growth of Sn‐doped Bi dendritic electrode with numerous labyrinthine and porous channels to provide abundant tips, edges, terraces, and low coordination sites for efficient conversion of CO2 into formate. As a result, the dendritic Sn‐doped Bi achieves a high partial current density (30 mA/cm2), a high Faradic efficiency of formate (95.5%), and a long‐term durability (>60 h). Most remarkably, the self‐made bipolar membrane can effectually prohibit the cross‐over of formate from cathode to anode and the oxidization of small organic molecules in anode can promote the production of formate on both anode and cathode sides. This work provides helpful insights to the design of electrocatalysts, bipolar membrane, and ultrathin liquid reactor.image
Energy and economic analysis feasibility of CO2capture on a natural gas internal combustion engine
Authors: García‐Mariaca Alexander , Llera‐Sastresa Eva 
Published: August 2022

AbstractCO2capture by amine scrubbing is a widely developed technology in its most advanced stage of evolution. However, it has never been used to capture CO2from mobile sources. The present study performs an energy and economic analysis of an amine scrubbing CO2capture storage (CCS) system, which takes for the amine regeneration process the waste heat from the exhaust gases of a turbocharged natural gas internal combustion engine (mobile source). The selected engine for the study is an M936G, widely used in freight and passenger transport. A primary and a tertiary amine were chosen for the simulations. In order to reduce volume and increase autonomy, captured CO2is stored as a liquid, therefore, a specific installation is planned. The system is hybridised with an organic rankine cycle (ORC) to reduce the energy penalty on the CCS system. Results show that a CCS system operating with Monoethanolamine (MEA) at 30 wt% achieved a maximum CO2capture rate of 66%, with a penalty over the power engine of only 10%. On the other hand, the economic analysis showed that the CCS system with MEA and without ORC is 31.8% cheaper than a hydrogen fuel cells bus and 26% cheaper than a battery‐electric bus. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.

Published: August 2022

AbstractIn this study, the lattice Boltzmann method is used to explore the double‐diffusive natural convection within a shallow enclosure with a built‐in rectangular blockage at its geometric center. The enclosure is exposed to an external magnetic field. One of the enclosure walls is subjected to linearly/sinusoidal heating and concentration conditions. The rectangular blockage is at higher temperature and concentration conditions. Numerical experimentation is executed for a range of parameters such as Rayleigh number , Lewis number , buoyancy ratio , aspect ratio of the enclosure , aspect ratio of the built‐in blockage , and Hartmann number . The working fluid is assumed to be liquid metal (sodium–potassium alloy, ). The complex interaction of flow parameters with the nonuniform heating and concentration conditions has been explored. Higher heat and mass transfer (HMT) rates are noticed for the sinusoidal temperature and concentration profile compared to linear for a given . and showed enhancement by , and for sinusoidal temperature and concentration profile of the enclosure as compared to linear for . The increase in the blockage and the enclosure aspect ratio shows augmentation in the HMT rate. The consequences of the study are also summarized in terms of empirical correlations of the and numbers showing functional dependence on the considered range of parameters.

AbstractA considerable effort has been made to draw out the flow properties of the magnetohydrodynamic fluid in parabolic movement with several parameters under cross‐diffusion. The novelty in the examination is the angle of inclination with a permeable vertical plate. The purpose of the work is to analyze the impact of some parameters on the flow in two cases, namely, obtuse angle and acute angle. The solution of the flow‐governed equations is attained by the utilization of the finite divergence technique in explicit type. The nature of the fluid velocity is observed in the cases of acute angle and obtuse angle and described accordingly with the use of graphs and tables. The validation of the method is checked with the published outcomes and pointed out a fine agreement with it. One of the major findings is that for increasing values of porosity the velocity enhances in the case of an acute angle and falls in the case of an obtuse angle.

AbstractQuality of early family interactions has been associated with child development, bonding, and mental health. Childhood adversity, stress, and depression impact parenting, affecting the quality of the interaction within the mother‐father‐child triad. The aim of the present study was to analyze the influence of parents’ adverse childhood experiences, depressive symptoms, and parental stress, on their sensitive response toward their tooddler and quality of traidic interactions. A correlational cross‐sectional method was used. The sample included 80 mother–father–child triads, of toddlers with social–emotional difficulties. Parents early adverse experiences, parental stress, and depressive symptoms were assessed through self‐report measures. Observational measures on parental sensitivity and triadic interaction were used. For mothers and fathers, adverse childhood experiences were associated with depressive symptoms in adulthood. Sensitivity toward their child and stress were positively associated among both parents. Symptoms of depression in mothers were associated with lower sensitivity toward their child, but in fathers, their sensitive response was influenced by the level of parental stress in the mother. In both parents, greater sensitivity in the dyadic interaction with the child was associated with a higher quality of the triadic interactions, in the triad as a whole, and in the regulation and involvement of the child.

AbstractConceptualizingThe next patient interaction is logical, essential, and largely done intuitively.Main purposeTo design and test a succinct learning guide for student guidance and student‐faculty interaction in conceptualizing the next patient interaction.MethodsIn 2021 and 2022, faculty scored questions from 1–5: Recognize deviation from the ideal? Articulate how and how much the situation deviated? Gage consequences of the situation? Assess own capabilities? To what extent does the student have a clear grasp of the procedural outcome? Faculty were also given open‐ended questions.ResultsForty‐eight reports were completed, 25 D3 and 23 D4. Three hundred thirty‐five faculty entries were made in the questions calling for a 1–5 response out of a possible 336 responses. Statistically significant differences were noted. Students were better able to recognize the situation as different from ideal than to articulate how and how much the situation deviated. Students were better able to grasp how and how much this situation differs from the ideal than to assess own capabilities. D4 students were better able to recognize deviation from the ideal and to articulate how and how much the situation deviated than were D3 students. For open‐ended questions, more students were scored as “Prepared” than were scored as “Unsure” and “Missed” combined.ConclusionsThe exercise is seen as a succinct and constructive (nonjudgmental) path to guide the student's conceptualization of the next patient encounter before the encounter begins. Next steps will be incremental for wider use in a clinical teaching environment.

AbstractLaser scanning optical beam induced current (OBIC) microscopy has become a powerful and nondestructive alternative to other complicated methods like electron beam induced current (EBIC) microscopy, for high resolution defect analysis of electronic devices. OBIC is based on the generation of electron–hole pairs in the sample due to the raster scanning of a focused laser beam with energy equal or greater than the band gap energy and synchronized detection of resultant current profile with respect to the beam positions. OBIC is particularly suitable to localize defect sites caused by metal–semiconductor interdiffusion or electrostatic discharge (ESD). OBIC signals, thus, are capable of revealing the parameters/factors directly related to the reliability and efficiency of the electronic device under test (DUT). In this review, the basic principles of OBIC microscopy strategies and their notable applications in semiconductor device characterization are elucidated. An overview on the developments of OBIC microscopy is also presented. Specifically, the recent progresses on the following three OBIC measurement strategies have been reviewed, which include continuous laser based single photon OBIC, pulsed laser based single photon OBIC, and multiphoton OBIC microscopy for three‐dimensional mapping of photocurrent response of electronic devices at high spatiotemporal resolution. Challenges and future prospects of OBIC in characterizing complex electronic devices are also discussed.Highlights

AbstractDespite their clinical potential, Extracellular Vesicles (EVs) struggle to take the scene as a preeminent source of biomarkers in liquid biopsy. Limitations in the use of EVs origin from their inherent complexity and heterogeneity and from the sensitivity demand in detecting low to very low abundant disease‐specific sub‐populations. Such need can be met by digital detection, namely capable to reach the single‐molecule sensitivity. Here we set to compare, side by side, two digital detection platforms that have recently gained increasing importance in the field of EVs. The platforms, both commercially available, are based on the principles of the Single Particle Interferometric Reflectance Imaging Sensing (SP‐IRIS) and the Single Molecule Array technology (SiMoA) respectively. Sensitivity in immune‐phenotyping of a well characterized EV sample is reported, discussing possible applicative implications and rationales for alternative or complementary use of the two platforms in biomarker discovery or validation.

AbstractIn continuation of our program for synthesizing novel imidazotriazole scaffolds, we report herein the synthesis of new fifteen substituted and fused imidazotriazole derivatives via different addition and cyclocondensation pathways. Thirteen compounds have been tested for their antiproliferative activity against 60 NCI cell lines. Compounds 3, 15 and 17 were the most active among the synthesized series. Imidazo[2,1‐c][1,2,4]triazolone derivative 3 showed high activity against leukemia K‐562 (51.00%), RPMI‐8226 (68.36%) and breast cancer MCF‐7 (56.76%) cell lines. While compound 15 exhibited high potency against colon cancer HCT‐15 (59.33%), CNS cancer SNB‐75 (57.06%) and renal cancer UO‐31 (50.5%) cell lines. Bis[1,2,4]triazolopurin‐7‐one derivative 17 showed strong activity against CNS cancer SNB‐75 cell line (54.32%). Compounds 3, 15 and 17 were evaluated through molecular modeling and docking techniques to give us a closer look on their binding mode with CDK2. The in vitro inhibitory activity against CDK2 was also performed for compounds 3 and 17. Compound 3 was subjected to further investigations by studying its effect on cell cycle progression and cell apoptosis in MCF‐7 cell line. It caused apoptosis, necrosis and induced cell cycle arrest at G2/M phase in MCF‐7 cell.

AbstractBackgroundDuring the COVID‐19 pandemic, hospitals did not allow caregiver visitation. Little is known about how caregivers' absence affected patients' care.ObjectiveThis study aimed to describe visitation restrictions' impact on patients and their caregivers experiences.DesignWe used a sequential explanatory mixed‐methods study design. First, we randomly selected 200 adult patients with cancer or heart failure hospitalized before (n = 100) and during visitor restrictions (n = 100) and abstracted data from the electronic medical record on communication between medical teams and caregivers and the topics discussed. Results from the quantitative analysis guided our thematic analysis of semi‐structured interviews conducted with a subsample of patients hospitalized during visitor restrictions and their caregivers to understand the impact of visitor restrictions on their experiences.ResultsCompared to prerestrictions, caregivers under visitation restrictions communicated less frequently with the medical team (29% vs. 37% of hospitalized days; p = .04), fewer received discharge counseling (37% vs. 52%; p = .04), and disproportionately more had no contact with the medical team (36% vs. 17%; p < .01). Video conferencing was documented for caregivers of only five patients. Qualitative analysis revealed that both caregivers and patients experienced emotional distress, increased conflict, and decreased perception of quality of care because of visitation restrictions.ConclusionsHospital visitor restrictions significantly reduced caregivers' communication with patients' medical team, causing caregivers and patients emotional distress. Protocols that facilitate communication between caregivers and care teams may benefit caregivers who cannot be physically present at care facilities, including distance caregivers.
