Published: January 2024

AbstractSoil phosphorus (P) loss induced by erosion is an imminent threat to global food security, and as the linkage between erosion and P loss, aggregate is the unit for soil P storage. This study investigated the impacts of soil texture on aggregate‐associated P and its enrichment rate by using soils with four typical textures (silty clay, clay loam, silty clay loam, and loam) from croplands with the same field management in Danjiangkou (Hubei, China), the water source for the Middle Route of South‐to‐North Water Diversion. The initial P concentration in the range of 36.5 to 411.2 mg kg−1 was generated by laboratory incubation, and aggregate‐associated P was determined by the combination of wet sieving and molybdenum blue colorimetric method. Aggregate‐associated P was shown to be mainly concentrated in <0.05 mm aggregates (23.20–315.52 mg kg−1), accounting for 30.71%–35.28% of P concentration for a unit mass of soil. In addition, aggregate‐associated P and its enrichment rate generally decreased with the decline of clay content (333.76–63.25 mg kg−1 in 1–0.5 mm size aggregate) under the same aggregate size fraction, while they all exhibited a unimodal distribution (increasing first and then decreasing) with decreasing aggregate size. Moreover, clay content made the most contribution to the increase of aggregate‐associated P (R2 > 0.56) and its enrichment rate (R2 = 64.4%, p < 0.01), while CaCO3 showed a contrary trend (R2 > 0.56, and R2 = 49.1%, p < 0.01). Collectively, variations of aggregate‐associated P and ERi were mainly attributed to soil clay fraction‐regulated P adsorption.

AbstractMAlSiN3:Eu2+ (M = Ca, Sr) is commonly used in high‐power phosphor‐converted white‐light‐emitting diodes and laser diodes to promote their color‐rendering index. However, the wide application of this phosphor is limited by the degradation of its luminescent properties in high‐temperature, high‐humidity, and high‐sulfur‐content environment. Here, the degradation mechanism of the (Sr,Ca)AlSiN3:Eu2+ (SCASN) red phosphor under thermal‐moisture‐sulfur coupling conditions is investigated. Furthermore, by performing first‐principles calculations, the hydrolysis mechanism on an atomic scale is assessed. The adsorption energy (Eads) and charge transfer (ΔQ) results showed that H2O chemically adsorbed on the (0 1 0), (3 1 0), and (0 0 1) surfaces of the CaAlSiN3 (CASN) host lattice. The energy barrier for H2O dissociation is only 29.73 kJ mol−1 on the CASN (0 1 0) surface, indicating a high dissociation probability. The formation of NH3, Ca(OH)2, and CaAl2Si2O8 is confirmed by H+ tended to combine with surface N atoms, while OH− combined with the surface Al/Si or Ca atoms. Moreover, ab initio molecular dynamics simulations were performed to further understand the hydrolysis process. This work offers a guidance on the design and applications of luminescent materials in LED packages with higher reliability and stability requirements in harsh environment.
Chiral Meta‐Coder for Spin Switchable Electromagnetic Camouflage and Information Authentication

Published: January 2024

AbstractElectromagnetic camouflage is crucial for concealing the physical identity of the object from external electromagnetic detection, whether in military operations or civilian contexts. However, addressing the pressing issue of seamlessly transitioning between camouflage and visualization capabilities is a significant challenge. By combining chiral meta‐atoms and irregular phase encoding method, a novel chiral meta‐coder is proposed for spin switchable electromagnetic camouflage and target authentication. Different from traditional conformal strategies, this meta‐coder achieves camouflage functionality by tightly arranging meta‐atoms around the target object and encoding suitable phase sequences to shape desired wavefront. Simultaneously, the target object can also be identified by modulating the helical state of the incident wave. As a proof of concept, a chiral meta‐coder operating in camouflaging “A” shaped target object is designed and experimentally demonstrated. When exposed to right circularly polarized waves, the meta‐atoms surrounding the object can adapt the wavefront to conceal target information. The camouflaged pattern exhibits diffuse scattering in the far field and three focal patterns around the near field. Conversely, these meta‐atoms transition into a wave‐absorbing configuration, facilitating the precise identification of target information. Such a strategy may find potential applications in data security, privacy, and communication.
THE CASE FOR BEING HUMAN AND LEADING HUMAN
Authors: Nash Jennifer 
Published: January 2024

AbstractThe author is a leadership expert/consultant/educator with considerable experience in coaching. “In my research on how leaders drive performance,” she writes, “I’ve found the key to successful leadership is becoming technically proficient in the human element. Prioritizing the human element means shifting focus away from profitability or processes to put people first.” These insights led to her creation of the “Human Leadership operating model.” She describes six elements of this framework, in the text and in Figure 1: hearing, understanding, mattering, appreciating, inspiring, and seeing. Within each she notes barriers, plus strategies for improvement. For instance: “Hearing someone isn’t just a matter of physically listening to their speaking sounds. It’s receiving their words with an open mind to understand their perspective.” And in the second element: “Understanding means gaining insight into others’ reality and viewing the world from their perspective. You listen to what they say and comprehend the meaning and essence of their words.” Third: “Everyone wants to feel that they are important and significant to others. It’s a universal human need to feel valued for our contributions to the world as well as for our humanity.” She concludes that “nurturing these six elemental needs improves work relationships and culture exponentially.”

Published: January 2024

AbstractFor a guided bone regeneration membrane, it is critical to possess osteogenic capability while inhibiting infection caused by bacteria. Inspired by the bilayer structure of the native periosteum, an electrospun Janus membrane with osteogenic and antibacterial dual‐function is fabricated for guided bone regeneration. Hydrophilic moxifloxacin (MXF) and hydrophobic icariin (ICA) are loaded in the nanofibers made of a mixture of polycaprolactone and gelatin at the top and bottom layers, respectively, leading to the opposing hydrophilic/hydrophobic properties of the bilayer Janus membranes. The as‐obtained Janus membrane exhibits excellent physical properties (tensile strength > 6.0 MPa) and robust biocompatibility, indicating the immense potential as a suitable replacement for the native periosteum. The membrane has a superior surface morphology and outstanding degradation performance in vitro. Besides, the rapid release of MXF and the slow release of ICA can meet the different needs of drug release rates. Only ≈30% ICA is released from the as‐obtained Janus membrane after 21 d while almost 80% MXF is released. Mimicking the bilayer structure of the native periosteum, the electrospun Janus membrane containing ICA and MXF exhibits excellent comprehensive properties, which provides a promising strategy for preparing multifunctional scaffolds for tissue engineering.
Is this really me? Investigating brand personality self‐congruity on consumer behavior in video‐based social media

Published: January 2024

AbstractThis research aims to explore the role of brand personality self‐congruity (BPC) in affecting consumers' purchase behavior in a particular setting: video‐based social media (i.e., TikTok). Moreover, we test the moderating role of consumers' emotional attachment to the influencer and the mediating role of brand engagement in affecting purchase intention. Finally, we delve into the antecedents of influencer effectiveness and their relationship with consumers' actual purchases. To do so, we leverage two quantitative studies (n1 = 248; n3 = 247) and a qualitative one. Results from Study 1 indicate that the lower consumers perceive the gap between the brand personality and self‐image, the more they are inclined to engage with and purchase a brand. Moreover, we find that the emotional attachment to the influencer does not play a role in influencing purchase intention, positing that emotional attachment and BPC have different emotion dynamics with different purchase outcomes. Building on Study 1, Study 2 leverages a focus group to identify the antecedents of influencer effectiveness. Results highlight that a sense of indulgence appears in the minds of consumers when confronted with brands that have a lower congruity with their self. This sense of indulgence, in the case of low BPC, hinders the ability of the influencer to create an engagement between the brand and the consumer. Finally, Study 3 quantitatively tests the antecedents of influencer effectiveness under two conditions (entertaining vs. informative content type) highlighting the different influence of the antecedents on individuals with high (vs. low) BPC.

Minimum quality regulations and the demand for childcare labor
Authors: Ali Umair , Herbst Chris M. , Makridis Christos A. 
Published: January 2024

AbstractMinimum quality regulations are often justified in the childcare market because of the presence of information frictions between parents and providers. However, regulations can also have unintended consequences for the quantity and quality of services provided. In this paper, we merge new data on states’ childcare regulations for maximum classroom group sizes and child‐to‐staff ratios with the universe of online job postings to study the impact of regulations on the demand for and characteristics of childcare labor. Our identification strategy exploits the unprecedented variation in regulatory reform during the COVID‐19 pandemic, relying on changes both within states over time and across children's age groups. We find evidence that these regulations reduce the number of childcare job postings and encourage providers to substitute away from higher‐skilled postings, thereby increasing the number of positions that are out‐of‐compliance with states’ teacher education requirements. In sum, the results imply that childcare regulations may reduce the demand for childcare labor, while simultaneously altering the composition of the workforce.

ABSTRACTImportanceSystemic lupus erythematosus (SLE) is a diffuse connective tissue disease with complex clinical manifestations and prolonged course. The early diagnosis and condition monitoring of SLE are crucial to disease prognosis.ObjectiveTo assess the diagnostic value of long noncoding RNA (lncRNA) nuclear enriched abundant transcript 1 (NEAT1) in childhood‐onset SLE (cSLE).MethodsFifty‐seven children diagnosed with SLE, 40 children diagnosed with juvenile idiopathic arthritis (JIA), and 40 healthy children were included. Peripheral blood samples from each patient were collected. A quantitative polymerase chain reaction was used to confirm the expression of lncNEAT1_1 and lncNEAT1_2 in peripheral blood. Associations among parameters were analyzed using the Mann‐Whitney U test or independent sample t‐test.ResultsThe expression of both lncNEAT1_1 and lncNEAT1_2 in patients with cSLE were significantly higher than that of healthy control and patients with JIA. Receiver operating characteristic curves revealed an area under the curve (AUC) of 0.633 (95% confidence interval [CI], 0.524–0.742; P = 0.024) for lncNEAT1_1. The AUC of lncNEAT1_2 was 0.812 (95% CI, 0.727–0.897; P < 0.0001) to discriminate individuals with cSLE from health control and children with JIA with a sensitivity of 0.622 and a specificity of 0.925. Moreover, lncNEAT1_2 expression was higher in patients with cSLE presenting with fever, lupus nephritis, elevated erythrocyte sedimentation rate, active disease activity, and decreased C3 level, compared with those without these conditions. However, no similar correlation was observed for lncNEAT1_1.InterpretationThe expression of lncNEAT1_2 was significantly elevated in children with SLE, especially those with fever, renal involvement, and low C3 levels. These findings suggest that lncNEAT1_2 may represent a potential biomarker for cSLE.
Robust switching control design using Lur'e Lyapunov functions
Authors: Ndoye Aboubacar , Trégouët Jean‐François 
Published: January 2024

AbstractThis article addresses the problem of robust output regulation for uncertain switched systems. A general result is first proposed for the case of uncertain and nonlinear systems. In order to cope with model uncertainties, the proposed approach implements the internal model principle. Local asymptotic stability of the closed‐loop system as well as zero steady state error on the controlled output are proven using Lur'e Lyapunov functions. Then, this result is specialized to the linear case. Sufficient conditions ensuring global or local stability of the closed loop system are provided. Furthermore, a constructive method based on LMI is presented. When only local stability is achieved, outcomes of this procedure are not only the controller gains, but also an estimation of the robust domain of attraction. Finally, illustrative examples are proposed, showing the efficiency of the proposed methods.

Published: January 2024

Among the nondestructive carbon material characterization tools, the prominence of visible Raman spectroscopy has surged remarkably for many years due to its ability to explore a diverse array of carbon bonding configurations. However, to fully unlock the distinctive features concealed within carbon composite materials, additional specimen treatments or precise spectroscope calibrations are necessary. In the same regard, the tiny diamond grain size (5–10 nm) and the pronounced amount of sp2 carbon in the ultrananocrystalline diamond film represent major challenges in visible light excitation. In this work, we employ calibrated oxygen plasma reactive ion etching conditions to manifest the nanodiamond visible Raman signature from ultrananocrystalline diamond/amorphous carbon composite (UNCD/a‐C) films fabricated by coaxial arc plasma deposition. Upon plasma etching, the broad defect band in the visible Raman spectra converged toward the diamond characteristic Raman peak at 1332 cm−1. A detailed explanation of band components of the Raman spectra is extracted through peak fitting procedures. The results of Raman spectroscopy are further correlated with the electrical characteristics of the nitrogen‐doped UNCD/a‐C films due to the optimized oxygen plasma etching processes.

Published: January 2024

AbstractCyanogen chloride (CNCl) is a highly toxic agent, but there is currently a lack of research on the catalytic hydrolysis reaction of CNCl on metal surfaces. The low efficiency and unclear mechanism of CNCl hydrolysis reaction have hampered the development and enhancement of protective equipment. In this work, we focused on investigating the adsorption behavior and hydrolysis mechanism of CNCl on copper and chromium surfaces through first‐principle methods. Our findings revealed the most stable adsorption configuration of CNCl on metal surfaces and its terminal flipping behavior during the hydrolysis process. Subsequently, we designed and studied a series of CNCl hydrolysis reaction pathways, primarily involving C‐terminal intermediates. Notably, the adsorption energy of CN* displayed strong linear scaling relationships with that of other key reaction intermediates, directly influencing the activity and selectivity of CNCl hydrolysis. By employing the adsorption energy expression based on the intrinsic properties of substrates and adsorbates, we extended them to identify the adsorption energies of various complex reaction intermediates involved in CNCl hydrolysis. This comprehensive understanding of the reaction mechanism on metal surfaces provides a theoretical foundation and innovative perspective for the further exploration of CNCl hydrolysis catalysts.

Published: January 2024

AbstractThe 31P NMR Chemical Shifts(δP) of Trimethylphosphine Oxide (TMPO) conjugated with ten common liquid molecular acids have been calculated employing the Density Functional Theory (DFT) based computational method. These shifts have been correlated with the intrinsic acid strength parameter, Deprotonation Energy (DPE), of the underlying acids and the complexation energy of TMPO (ΔΕ). The acids, anions, and conjugated complexes were modeled with PW91 functional and 6‐31++G(d,p) basis set. The NMR calculations were performed on the relaxed structures as single‐point calculations using the Gauge Including Atomic Orbital (GIAO) method at the MP2 level and TZVP basis set. Poor linearity was observed in the correlation of δP with respect to DPE (R2=0.867), while strong linearity was seen with the complexation energy ΔΕ (R2=0.967). We have hypothesized the unreliable modeling of anions and Non‐Covalent Interactions (NCI) to be the factors affecting the linear trend of δP with respect to DPE. To support our hypothesis, we have presented Reduced Density Gradient (RDG) Maps and 31P NMR Tensor spatial orientation data of the Acid‐TMPO conjugates.

Published: January 2024

AbstractVanadium nitride (VN) is a promising electrode material for sodium‐ion storage due to its multivalent states and high electrical conductivity. However, its electrochemical performance has not been fully explored and the storage mechanism remains to be clarified up to date. Here, the possibility of VN/carbon hybrid nanorods synthesized from a metal–organic framework for ultrafast and durable sodium‐ion storage is demonstrated. The VN/carbon electrode delivers a high specific capacity (352 mA h g−1), fast‐charging capability (within 47.5 s), and ultralong cycling stability (10 000 cycles) for sodium‐ion storage. In situ XRD characterization and density functional theory (DFT) calculations reveal that surface‐redox reactions at vanadium sites are the dominant sodium‐ion storage mechanism. An energy‐power balanced hybrid capacitor device is verified by assembling the VN/carbon anode and active carbon cathode, and it shows a maximum energy density of 103 Wh kg−1 at a power density of 113 W kg−1.

Published: January 2024

AbstractThe engineering of amorphous metal‐organic frameworks (MOFs) offers potential opportunities for the construction of electrocatalysts for efficient oxygen evolution reaction (OER). Herein, highly efficient OER performance and durability in alkaline electrolyte are discovered for MOF‐derived amorphous and porous electrocatalysts, which are synthesized in a brief procedure and can be facilely produced in scalable quantities. The structural inheritance of MOF amorphous catalysts is significant for the retention of catalytic sites and the diffusion of electrolytes, and the presence of Fe sites can change the electronic structure and effectively control the adsorption behavior of important intermediates, accelerating reaction kinetics. The obtained amorphous A‐FeNi can be transformed from FeNi‐MOF effortlessly and instantly, and it only needs low overpotentials of 152 and 232 mV at 10 and 100 mA cm−2 with a Tafel slope of 17 mV dec−1 in 1 m KOH for OER. Moreover, A‐FeNi possesses high corrosion resistance and durability, therefore A‐FeNi can work continually for at least 400 h at 100 mA cm−2. This work may pave a new avenue for the design of MOFs‐related amorphous electrocatalyst.

Published: January 2024

In this article, the influence of the Fe2O3 addition amount on the dephosphorization kinetics of hot metal at the low slag basicity (CaO/SiO2) of about 1.6 and low temperature of 1623 K is investigated with laboratorial experiments and the kinetic model. Si and P contents in the hot metal during the whole dephosphorization process, and the endpoint FeO content in the slag, show good agreements between the calculated results with the kinetic model and experimental results. The peak value of dephosphorization rate linearly increases from 8.35 × 10−5 to 4.52 × 10−4 mass% s−1 when the weight ratio of Fe2O3 is increased from 5 to 10/100 g hot metal. With the increase in Fe2O3 addition amount, the mass transfer coefficient in the hot metal phase (km) and that in the slag phase (ks) and dephosphorization rate constant (k) all increase. The value of km is found to be 4.34 times that of ks. During the dephosphorization process, the rate‐controlling step converts from the mass transfer in slag phase to the mass transfer in hot metal phase in less than 10 min. With the increase in Fe2O3 addition amount, the value of interfacial oxygen activity of increases from 0.0102 to 0.0201.
