Published: June 2022

AbstractChiral metal‐halide hybrids have aroused widespread attention owing to their chemical and structural versatilities as well as unique optoelectronic and spin‐dependent properties. Several recent experiments have shown that organic chirality results in circularly polarized absorption and emission from the inorganic metal‐halide subcomponent; however, the exact structure chirality transfer mechanism and structure‐optical‐activity relation remain elusive. Here, we demonstrate how chiral organic cations lead to local structural asymmetry in a new series of chiral antimony‐halide hybrids, including zero‐dimensional edge‐shared (0D, A4Sb2X10, A=(R)‐(+)‐α‐methylbenzylammonium (R‐MBAH+) or (R)‐(−)‐1‐cyclohexylethylammonium (R‐CHEAH+), X=Br, I) and one‐dimensional corner‐shared (1D, A’2SbX5, A’=(R)‐(+)‐α‐ethylbenzylammonium (R‐EBAH+); X=Br, I). Structure analysis shows that organic ammoniums distort the antimony‐halide octahedra through asymmetric hydrogen bonding. The chiroptical activity is correlated with the exciton coupling strength, which can be tuned by the structural dimensionality. Our study unveils the molecular scale chirality transfer mechanism in these chiral metal‐halide hybrids.

Published: June 2022

SummaryEnergy storage systems (ESS) provide buildings with the ability to store electricity generated from renewable energy sources (eg, solar photovoltaics), increasing building operational flexibility and reliability. Previous studies on ESS in buildings often make assumptions about key input parameters (eg, installation factor, roundtrip efficiency, etc.) being fixed, overlooking potential performance risks due to uncertainty or variations in these parameters. The goal of this paper is to quantify the impact of uncertainty in technical and financial parameters on the economic performance of Li‐ion batteries (LIB), proton‐exchange membranes reversible fuel cells (PEM RFC), and reversible solid oxide cells (RSOC). The analysis is conducted on three medium‐sized office buildings located in three different climate zones of the United States: 2B (Phoenix, AZ), 3B‐Coast (Los Angeles, CA), and 4C (Seattle, WA). Two metrics are used to evaluate the economic viability of the selected technologies, namely the levelized cost of electricity (LCOE) and the levelized cost of energy storage (LCOS). While the results of the LCOE and LCOS differed in value between those cities, the cost breakdown for LCOS in all locations shows that capital cost is the biggest cost contributor, followed by electricity cost. A Monte‐Carlo simulation was also conducted to assess the impact of uncertainty in input parameters on the LCOS model. The simulation results allowed us to generate probable ranges and probability tables for the LCOS.

AbstractThe global prevalence of prediabetes is on the rise, and it is of value to manage prediabetes and predisposal to diabetes at an early stage. Myricetin is a natural polyhydroxyflavonoid, found in planta with several health benefits. This study aimed to evaluate the effects of myricetin on prediabetes. In vitro assay indicated that the cell viability, endocytosis and phagocytosis of macrophages were inhibited in RAW 264.7 cells under high glucose (HG) levels, concurrent with an increase in reactive oxygen species level. Administration of myricetin at a dose of 10 μM, restored the immunosuppressive effects mediated by HG. Moreover, the viability of Jurkat cells was also inhibited concurrent with inhibition of interleukin‐2 (IL‐2) and interferon‐gamma (IFN‐γ) expression levels versus increase PD‐1 after treated with myricetin at the dose of 10 μM. In a prediabetic mouse model fed with high fat diet, increase in body weight, fat mass, fasting blood glucose, Triglyceride (TG), total cholesterol (TC) and low‐density lipoprotein cholesterol (LDL‐C) were observed. Flow cytometry analysis revealed a significant decrease in CD8+ T cells in the spleen and blood, whereas the expression of PD‐1 on CD3+, CD4+, and CD8+ T cells in the spleen and lymph was significantly elevated. Administration of myricetin showed a potential hypoglycemic and lipid‐lowering effect in both prevention and treatment, in addition to restoration of innate and adaptive immune immunity in mice and confirmed by the in vitro immunomodulation effect. In addition, 16S rRNA showed that myricetin ameliorated prediabetes may be related to decrease in the relative abundance of Acetatifactor, Blautia, Intestinimonas, Anaerotruncus, and Peptococcus.

AbstractAs electric vehicles become more widely used, there is a higher demand for lithium‐ion batteries (LIBs) and hence a greater incentive to find better ways to recycle these at their end‐of‐life (EOL). This work focuses on the process of reclamation and re‐use of cathode material from LIBs. Black mass containing mixed LiMn2O4 and Ni0.8Co0.15Al0.05O2 from a Nissan Leaf pouch cell are recovered via two different recycling routes, shredding or disassembly. The waste material stream purity is compared for both processes, less aluminium and copper impurities are present in the disassembled waste stream. The reclaimed black mass is further treated to reclaim the transition metals in a salt solution, Ni, Mn, Co ratios are adjusted in order to synthesize an upcycled cathode, LiNi0.6Mn0.2Co0.2O2 via a co‐precipitation method. The two reclamation processes (disassembly and shredding) are evaluated based on the purity of the reclaimed material, the performance of the remanufactured cell, and the energy required for the complete process. The electrochemical performance of recycled material is comparable to that of as‐manufactured cathode material, indicating no detrimental effect of purified recycled transition metal content. This research represents an important step toward scalable approaches to the recycling of EOL cathode material in LIBs.

Published: June 2022

AbstractThe impact of energy‐based volumetric internal heating and magnetic field‐dependent (MFD) viscosity on the onset of ferrothermal porous convection for different types of boundary conditions is investigated. The lower and upper boundaries are considered to be either rigid or stress‐free. The lower boundary is insulating, while at the upper boundary a Robin type of thermal condition is applied. Besides this, a general type of boundary conditions is invoked on the magnetic potential. The stability eigenvalue problem is solved numerically using the Galerkin‐type of weighted residuals technique with the Rayleigh number, as the eigenvalue. The results obtained for different boundary combinations are found to be qualitatively similar though not quantitatively. The effect of Biot number, MFD viscosity, and porous parameters is to hinder, while the influence of internal heat source strength, magnetic number, and the nonlinearity of fluid magnetization is to advance the onset of convection. The rigid and conducting boundaries offer a more stabilizing influence on the onset when compared to stress‐free and insulating boundaries. The convection cells get contracted the most when the boundaries are rigid and also when the upper boundary is conducting. The results delineated under the limiting cases are found to be in good agreement with those available in the literature.

AbstractWe set out to investigate the effects of gadodiamide and gadoteric acid, used for magnetic resonance imaging, on the lungs. In this study, 32 male Sprague Dawley rats were used. These were allocated into four groups; The first group (control) was untreated. The second group received isotonic saline on the first and fourth days of the week for 5 weeks. Following the same schedule, the third and fourth groups received a total of 2 mg/kg gadodiamide and gadoteric acid, respectively, in place of saline. The alveolar Wall thickness was evaluated. Gadodiamide and gadoteric acid significantly increased the numbers of collagen‐3 and caspase‐3 positive cells in the lung tissue (p < 0.05). In addition, these two substances increased the alveolar Wall thickness (p < 0.05). Furthermore, they increased the levels of malondialdehyde and glutathione (p < 0.05). This study demonstrates that both linear and macrocyclic contrast agents are toxic for the lungs in rats.

AbstractRising trends in freshwater salinity, collectively termed the Freshwater Salinization Syndrome (FSS), constitute a global environmental concern. Given that the FSS has been observed in diverse settings, key questions regarding the causes, trend magnitudes, and consequences remain. Prior work hypothesized that FSS is driven by state factors, such as human‐centered land use change, geology, and climate. Here, we identify the fundamental overriding factors driving FSS within the northeastern United States and quantify the diversity of FSS severity within the region. Specifically, we analyzed decadal‐scale trends in specific conductance (a salinity proxy) for 333 lotic sites over four decades. Next, we quantified potential variables driving the rising or falling trends, including impervious surface cover (ISC), winter temperature and precipitation, watershed size, and ambient conductance. Temperature and ISC were considered the most likely candidates for predicting FSS severity because road salts have previously emerged as the fundamental regional driver. Most (62.5%) sites exhibited patterns of significantly increasing conductance; thus, the overall regional state reflects advancing FSS. However, others exhibited an absence of change (28.8%) or decreasing values (8.7%), and slope magnitude did change with latitude. Linear modeling demonstrated that two variables—ISC and watershed size—constitute the best predictors of long‐term conductance trends and that an intercept not significantly different than zero suggests that the FSS does not reign in the absence of urbanization. We also detected areas with consistently decreasing trends despite moderate ISC. Therefore, within the region, advancing urbanization causes the typical condition of advancing FSS, but heterogeneity also exists.

AbstractAmong the mechanisms of suppression that T regulatory (Treg) cells exert to control the immune responses, the secretion of small extracellular vesicles (sEV) has been recently proposed as a novel contact‐independent immunomodulatory mechanism. Previous studies have demonstrated that Treg cells produce sEV, including exosomes, able to modulate the effector function of CD4+ T cells, and antigen presenting cells (APCs) such as dendritic cells (DCs) through the transfer of microRNA, cytokines, the production of adenosine, among others. Previously, we have demonstrated that Neuropilin‐1 (Nrp1) is required for Tregs‐mediated immunosuppression mainly by impacting on the phenotype and function of effector CD4+ T cells. Here, we show that Foxp3+ Treg cells secrete sEV, which bear Nrp1 in their membrane. These sEV modulate effector CD4+ T cell phenotype and proliferation in vitro in a Nrp1‐dependent manner. Proteomic analysis indicated that sEV obtained from wild type (wt) and Nrp1KO Treg cells differed in proteins related to immune tolerance, finding less representation of CD73 and Granzyme B in sEV obtained from Nrp1KO Treg cells. Likewise, we show that Nrp1 is required in Treg cell‐derived sEV for inducing skin transplantation tolerance, since a reduction in graft survival and an increase on M1/M2 ratio were found in animals treated with Nrp1KO Treg cell‐derived sEV. Altogether, this study describes for the first time that Treg cells secrete sEV containing Nrp1 and that this protein, among others, is necessary to promote transplantation tolerance in vivo via sEV local administration.
Start with why: The transfer of work meaningfulness from leaders to followers and the role of dyadic tenure

Published: June 2022

SummaryLeaders are expected to enhance the work meaningfulness of followers, but little insight exists on the role of leaders' own experience of meaningfulness in that process. We propose a leader–follower transfer model of work meaningfulness through visionary leadership, grounded in self‐concept‐based theory, in which leader–follower dyadic tenure shapes the effects of visionary leadership on followers. Moreover, we suggest that work meaningfulness can enhance followers' goal achievement and reduce turnover intentions. We tested and confirmed our moderated‐mediation model in two independent, multisource, multilevel field data sets of 79 mid‐level leaders and 871 employees in Study 1 and 68 CEOs and 596 mid‐level leaders in Study 2. We also empirically ruled out a series of alternative transfer mechanisms, including transformational and transactional leadership, leader–member exchange, and all subdimensions of transformational leadership. This research contributes to the scholarly discussions on work meaningfulness and visionary leadership and offers novel insights for practitioners to enhance work meaningfulness in their organizations.

AbstractBackgroundThickening of the ligamentum flavum is considered to be the main factor for lumbar spinal canal stenosis (LSCS). Although some mechanisms have been speculated in the thickening of the ligamentum flavum, there are only a few comprehensive approaches to investigate its pathology. The objective of this study was to investigate the pathology of thickened ligamentum flavum in patients with LSCS based on protein expression levels using shotgun proteome analysis.MethodsLigamentum flavum samples were collected from four patients with LSCS (LSCS group) and four patients with lumbar disc herniation (LDH) as controls (LDH group). Protein mixtures were digested and analyzed by liquid chromatography/mass spectrometry analysis. To compare protein expression levels between the LSCS and LDH groups, the mean Mascot score was compared. Biological processes were assessed using Gene Ontology analysis.ResultsA total of 1151 proteins were identified in some samples of ligamentum flavum. Among these, 145 proteins were detected only in the LSCS group, 315 in the LDH group, and 691 in both groups. The demonstrated biological processes occurring in the LSCS group included: extracellular matrix organization, regulation of peptidase activity, extracellular matrix disassembly, and negative regulation of cell growth. Proteins related to fibrosis, chondrometaplasia, and amyloid deposition were found highly expressed in the LSCS group compared with those in the LDH group.ConclusionsTissue repair via fibrosis, chondrometaplasia, and amyloid deposits may be important pathologies that occur in the thickened ligamentum flavum of patients with LSCS.

AbstractAvailability of suitable roosting sites influences distribution of wild turkeys (Meleagris gallopavo) across the landscape. In semi‐arid environments, roosts are limited to riparian corridors capable of supporting trees large enough to provide suitable roost sites. Gould's wild turkeys (M. g. mexicana) are spatially restricted to mountainous semi‐arid areas of southwestern United States and Mexico, and information on their distribution and habitat use is limited. We evaluated roost site selection and fidelity of Gould's wild turkeys relative to environmental gradients and forested land cover during 2016–2017 in southeastern Arizona, USA. We monitored 51 global positioning system (GPS)‐tagged individuals and collected 7,954 night roost locations. We quantified specific roost site characteristics at 274 unique roost locations. Gould's wild turkeys roosted in forested communities dominated by mature pine (Pinus spp.) and oak (Quercus spp.), and exhibited substantive roost site fidelity. Roost sites were selected at moderate elevations (range = 1,254–2,894 m), and were predominately on north‐facing slopes with slight incline (<11°), suggesting little plasticity in selection of roost sites. Conserving habitat with topography and vegetative structure similar to those described in our study is likely to improve ongoing restoration and management of Gould's wild turkeys.

ObjectivesHospital prices vary substantially for myringotomy with tympanostomy tube placement (M&T) and adenotonsillectomy (T&A). The Centers for Medicare and Medicaid Services recently implemented hospital price transparency requirements to help families make financially informed decisions about where to seek care. We sought to determine price availability and the extent of price variation for these procedures.MethodsWe performed a cross‐sectional analysis of the Turquoise Health Hospital Rates Data Platform, which extracts prices for facility fees from publicly available hospital chargemasters. We determined the proportion of hospitals serving pediatric patients that published payer‐specific prices for M&T and T&A. We additionally characterized the extent of variation in payer‐specific prices both across and within hospitals.ResultsApproximately 40% (n = 909 of 2,266 hospitals) serving pediatric patients disclosed prices for M&T or T&A. Among disclosing hospitals, across‐center ratios (adjusted for Medicare hospital wage indices) ranged from 11.0 (M&T; 10th percentile adjusted median price: $536.80 versus 90th percentile adjusted median price: $5,929.93) to 23.4 (revision adenoidectomy age >12 years; 10th percentile: $393.82 versus 90th percentile: $9,209.88). Median within‐center price ratios for procedures ranged from 2.2 to 2.7, indicating that some private payers reimbursed the same hospital more than twice as much as other payers for the same procedure.ConclusionThe majority of hospitals serving pediatric patients were non‐compliant with federal requirements to disclose prices for M&T and T&A. Among disclosing hospitals, there was wide variation in payer‐specific prices between and within institutions. Further research is necessary to understand whether disclosure of prices will enable families to make more financially informed decisions.Level of Evidence3 Laryngoscope, 133:948–955, 2023

Published: June 2022

AbstractLong‐wave infrared (LWIR) of 8–14 μm is an imperative atmospheric transmission window for applications such as infrared detectors, radiative cooling, and infrared stealth. Attempts to manipulate thermal emission in the LWIR band consist of either directional emission but narrowband or LWIR emission but non‐directional. Directional thermal emission covering the entire LWIR band has remained elusive, so far. Here, a whole LWIR directional thermal emitter is introduced consisting of top epsilon‐near‐zero (ENZ) films (SiO2/SiO/Al2O3), a dielectric gap (Ge), and bottom ENZ films (TiO2/Ta2O5) on a metal. The emitter exhibits high emissivity (>0.9) in p‐polarization at specific directions (72°–82°) covering the entire 8–14 μm atmospheric window. Additionally, infrared encryption information on the emitter can only be observed in p‐polarization in the oblique direction. This approach introduces a new route toward simultaneous control of bandwidth and directionality of thermal emission and has inclusive applications such as infrared camouflage and energy management.

Published: June 2022

AbstractCompared with traditional encryption methods, one‐time‐pad encryption shows theoretically unbreakable characteristics in cryptography owing to the randomness of the generated keys which are generally the same length as the target message. Here, a novel one‐time‐pad encryption strategy is proposed for combining one‐time‐pad keys storage and associated information authentication in metasurface platform. In the concept, visual secret sharing protocol is used to generated one‐time‐pad key by encoding each pixel of secret to two shared sub‐pixels, while each share reveals no information about original image. Then instead of overlaying the two shares to retrieve the secret, the two shares are further encoded to two random polarization key sequences of horizontal and vertical polarization states in an anisotropic metasurface for encryption. In decryption, a single anisotropic metasurface is adopted as the ciphertext to reconstruct target image combined with the doubly‐encrypted polarization keys. By replacing the conventional multichannel metasurface‐based encryption methods with the digital‐based one‐time‐pad encryption, this work enables the reusability of the metasurface and paves the way toward a new methodology for massive data storage.
