AbstractLithium‐ion batteries (LIBs) are the preeminent technology for energy storage, having the highest energy density for large‐scale commercial applications. Owing to üast assiduous studies, a good number of reported advanced anode materials possess excellent electrochemical properties. In this work, a porous C, N dual‐doped ZnO/Co composite is successfully prepared by metal–organic frameworks (MOF)‐template mediated synthesis method utilizing a self‐sacrificing template of bimetallic zeolitic imidazolate framework (denoted as ZnCo‐ZIF) and is tested as a lithium‐ion battery anode material. Due to the advantageous structural and morphological features, such as well‐defined open framework clusters with polyhedron crystal structure, conductive porous carbon network and synergistic effects, the as‐prepared C, N dual‐doped ZnO/Co electrode delivers a specific capacity of 800 mAh g‐1 at 0.2 A g‐1 for 500 cycles together with unprecedented cycling ability of 590 mAh g‐1 at 1 A g‐1 over 1000 cycles. Moreover, density functional theory (DFT) calculations demonstrate the relationship between the electronic structure and electrochemical activity of ZnO/Co anode material. These results show that the synthesized C, N dual‐doped ZnO/Co is a promising high‐performance anode material for LIBs.
Intrinsic Valley Polarization in Computationally Discovered Two‐Dimensional Ferrovalley Materials: LaI2and PrI2Monolayers
Authors: Sharan Abhishek , Singh Nirpendra 
Published: January 2022

AbstractFerrovalley materials with intrinsic valley polarization present a novel space for materials exploration suitable for valleytronic applications. Here, two Ferrovalley materials, LaI2and PrI2monolayers, exhibiting intrinsic valley polarizations of 28 and 35 meV, respectively, mediated by strong magnetic exchange interaction and spin‐orbit coupling are computationally discovered. The unconstrained crystal structure prediction algorithm is used to predict the structures of bulk LaI2and PrI2, which are layered and analogous to the 2H phase of transition metal dichalcogenides. The monolayers have small exfoliation energy (smaller than MoS2) and exhibit dynamical, mechanical, and thermodynamical stability, advocating their experimental realization. Valley polarization under the effect of bi‐axial strain is preserved and can be used to enhance valley splitting. Finally, the anomalous hall properties of both the monolayers under the effect of in‐plane electric field are discussed. Both the materials exhibit significant anomalous Hall conductivity with proper tuning of the Fermi level.
Multiparametric Material Functionality of Microtissue‐Based In Vitro Models as Alternatives to Animal Testing
Authors: Stengelin Elena , Thiele Julian , Seiffert Sebastian 
Published: January 2022

AbstractWith the definition of the 3R principle by Russel and Burch in 1959, the search for an adequate substitute for animal testing has become one of the most important tasks and challenges of this time, not only from an ethical, but also from a scientific, economic, and legal point of view. Microtissue‐based in vitro model systems offer a valuable approach to address this issue by accounting for the complexity of natural tissues in a simplified manner. To increase the functionality of these model systems and thus make their use as a substitute for animal testing more likely in the future, the fundamentals need to be continuously improved. Corresponding requirements exist in the development of multifunctional, hydrogel‐based materials, whose properties are considered in this review under the aspects of processability, adaptivity, biocompatibility, and stability/degradability.

Published: January 2022

AbstractBaCe0.8Y0.2O3−δ (BCY) is the most widely studied proton‐conducting material and is frequently fabricated as a dense membrane for hydrogen separation. However, the limitation of preparing dense BCY membranes is the extremely high sintering temperature (>1500°C). Herein, the BCY 7‐channel hollow fiber membrane was prepared by a one‐step thermal processing (OSTP) with Co2O3 as a sintering aid. The results showed that the addition of 1 wt.% Co2O3 at a reduced temperature of 1350°C was the optimum composition and sintering condition for densification and forming a single perovskite‐phase structure. The hydrogen permeation flux of the BCY hollow fiber membrane reached up to 0.34 ml min−1 cm−2 at 900°C. The long‐term stability test was conducted for 300 h. The successful attempt of such a strategy provides a green and straightforward path for the preparation of dense ceramic proton‐conducting membranes on a large scale. This promotes its industrial application in high‐temperature hydrogen separation.
Temperature‐Directed Formation of Anisotropic Kettlebell and Tadpole Nanostructures in the Absence of a Swelling‐Induced Solvent
Authors: Chen Sung‐Po R. , Bobrin Valentin A. , Jia Zhongfan , Monteiro Michael J. 
Published: January 2022

AbstractAnisotropic Janus (“snowman”) nanoparticles with a single protrusion are currently made via the solvent swelling‐induced method. Here, we demonstrate without the aid of toxic solvents a generally applicable method for the formation of anisotropic polymer nanoparticles directly in water by controlling polymer mobility through tuning its glass transition temperature (Tg). Spherical structures, formed immediately after the emulsion polymerization, transformed into uniform tadpoles (with head diameter ≈60 nm and tail length ≈130 nm) through the protrusion of a single cylindrical tail when cooled to a temperature above the Tg of the polymer. Cooling the spheres to below the Tg produced kinetically trapped kettlebell structures that could be freeze‐dried and rehydrated without any structural change. These unique kettlebells could transform into uniform tadpoles by heating above the Tg, representing a triggered and on‐demand structural reorganization.
Biophysicochemical studies of a ruthenium (II) nitrosyl thioether‐thiolate complex binding to BSA: Mechanistic information, molecular docking, and relationship to antibacterial and cytotoxic activities

Published: January 2022

The purpose of this study was to extensively explore in vitro protein binding to [Ru (NO)(Et2NpyS4)]Br (RuNOTSP) and its ligand (TSP), correlate the findings with antibacterial and cytotoxic effects, and try to answer the question: Is the metal center always important for binding? With the aid of stopped‐flow and other spectroscopic and computational methods, the interaction between RuNOTSP and TSP and bovine serum albumin (BSA) was studied and a mechanism was proposed. From UV–Vis and fluorescence experiments, a static quenching mechanism and binding constants at a single site demonstrated the higher stability of the RuNOTSP‐BSA system at 298 K compared with TSP‐BSA. Stopped‐flow experiments indicated that binding of RuNOTSP and TSP to BSA is accomplished mainly via a two‐step mechanism: a fast second‐order binding followed by a slow first‐order isomerization process. The first reaction step is reversible with coordinate affinity Ka1 190 (RuNOTSP) and 50 M−1 (TSP). The second step for RuNOTSP is a reversible reaction with Ka2 of 76.4 M−1, whereas an irreversible step that was observed with a K2 of 0.18 M−1 for TSP indicates that TSP‐BSA is kinetically more stable than RuNOTSP‐BSA. The results revealed that the ruthenium center not only improves reaction rate through coordination affinity but also changes the binding process. Mode and strength of interaction of RuNOTSP and TSP with protein have also been supported by molecular docking and showed that RuNOTSP is located in IA pocket (Trp134) with a binding affinity (−7.27 kcal/mol), a slightly lower than TSP (−8.05 kcal/mol), and these results are in agreement with the binding constants. Furthermore, antibacterial testing revealed that RuNOTSP and TSP had high antibacterial activity against both Gram‐positive and Gram‐negative bacteria. They are also highly cytotoxic to HepG2 human liver cancer cells. Because the TSP‐BSA complex is kinetically more stable than that of RuNOTSP, the former illustrated better antibacterial and cytotoxic activities.

Racism and the future of antiracism in education: A critical analysis of the Sewell Report
Authors: Tikly Leon 
Published: January 2022

AbstractThis article provides an analysis and critique of the education component of the 2021 Sewell Report on Race and Ethnic Disparities. Discussion focuses on the report’s spurious claims to objectivity, the erasure of racism and the inadequacy of its recommendations. It is suggested, however, that despite its many flaws, the Sewell Report poses challenges for those who have traditionally been aligned with antiracism in education. The article concludes by setting out a vision for a new progressive project aimed at advancing racial and cultural justice that, it is suggested, can begin to address these challenges.

AbstractThe triglyceride glucose (TyG) index and triglyceride/high lipoprotein density cholesterol (TG/HDL‐C) are two important risk markers to evaluate the insulin resistance and cardiovascular diseases (CVDs). To assess the association between TG/HDL‐C and TyG index and CVDs. The Mashhad stroke and heart association disorder cohort study started in 2010 and has been continued until 2020. During 6‐year follow‐up of 9704 participants, 235 events including 118 acute coronary syndrome (ACS), 83 chronic coronary syndrome, 27 myocardial infarction, and 27 cardiac death were confirmed. SPSS software (version 21) was used for statistical analysis and figures were drawn by GraphPad Prism 6 software. The prevalence of ACS and cardiac death were higher in the fourth quartile of serum TG/HDL‐C (>4.43) and higher prevalence of ACS was considered in subjects classified in the fourth quartile of TyG index (>8.98). A high TyG index was associated with an increased risk of ACS and cardiac death [1.362 (95% confidence interval [CI]: [1.013–1.831]) and 2.3 (95% CI: [1.247–4.241])] respectively; based on Cox regression analysis elevated TyG and TG/HDL‐C increased the chance of CVD by [1.634 (95% CI: 1.304–2.047) and 1.068 (95% CI: 1.031–1.105)], respectively. Our results strongly showed that TyG index and TG/HDL‐C are independent risk factors for incident CVD, suggesting that TyG index and TG/HDL‐C may be as an important unique biomarker for predicting CVD outcomes and progression.
Linking stakeholder and competitive pressure to Industry 4.0 and performance: Mediating effect of environmental commitment and green process innovation
Authors: Bhatia Manjot Singh , Kumar Saurabh 
Published: January 2022

AbstractIn the recent few years, with an increase in focus on sustainability, firms have been actively pursuing different strategies to contribute towards sustainability. Industry 4.0 (I4) technologies can help organizations to achieve superior environmental as well as economic performance. Through the lens of stakeholder theory (ST) and Schumpeterian view of competition (SCV), this paper examines whether stakeholder and competitive pressures towards sustainability stimulate organizations to implement I4 technologies and commensurate performance outcomes. The study further tests the mediating role of environmental commitment and green process innovation (GPI) on these relationships. The proposed hypotheses are examined using the survey data from 173 manufacturing firms in India by partial least squares (PLS) approach. Findings show that environmental commitment mediates the effect of stakeholder and competitive pressures on I4 technologies. Further, results also show that GPI mediates between I4 technologies and performance. The findings provide insights for managers on how they can best respond to stakeholder and competitive pressures on sustainability and contribute towards sustainable development.

AbstractBackground and ObjectivesEvidence regarding redo percutaneous interventions for recurrent mitral regurgitation is scarce. We ought to evaluate procedural and clinical outcomes of repeated edge‐to‐edge transcatheter mitral valve repair (TMVR) interventions.MethodsThis multicenter study collected individual data from eight high‐volume TMVR Centers in Spain. Between 2012 and 2020, all patients undergoing a second edge‐to‐edge TMVR intervention (Redo) were included in the study.ResultsAmong a total of 1028 procedures, 31 patients (3%) with residual MR ≥ 3 at follow‐up underwent a second procedure (Redo). Redo intervention was mainly conducted between the first and second year after the first procedure. The most common cause of MR progression was partial detachment (46.7%) followed by LV remodeling (35.5%). Procedural success was achieved in 87% of cases. After a mean follow‐up of 1.75 ± 1.54 years, all‐cause and cardiovascular mortality were 48.1% and 25%, respectively. Nearly half of the patients (48.1%) required at least one hospital admission for CHF within the follow‐up period. However, most of the patients presented symptomatic improvement as depicted by an NYHA class ≤2. Elective mitral surgery was conducted in only one patient at follow‐up due to insufficient MR reduction.ConclusionsAccording to our findings, redo edge‐to‐edge TMVR interventions were feasible and safe with a high procedural success rate. Clinical and echocardiographic follow‐up showed however modest long‐term results in this specific setting.

AbstractThe diagnosis of rabies, a potentially fatal neuroinfectious disease, should be strongly considered in all patients who develop encephalitis following an infected animal bite even when they have received post‐exposure prophylaxis. In the absence of confirmatory tests, typical magnetic resonance imaging findings help confirm the clinical diagnosis of rabies.

Published: January 2022

AbstractSingle entity electrochemistry is employed to gain insights into ion solvation in solvent mixtures. To this end, the time required for the oxidation of individual indicator nanoparticles to sparingly soluble products is used to probe ionic diffusion, and hence gain new insights into the solvation properties of solvent mixtures. Herein, water‐ethanol or water‐methanol mixtures of different compositions are analyzed following this new approach, using silver nanoparticle oxidation in the presence of chloride and iodide as a complementary indicator reaction. For increasing concentrations of the bulkier alcohol molecules in the mixtures with water, an increasing content of alcohol molecules in the halide's solvation shell is detected by the observation of hindered halide diffusion. The extent of this solvent replacement is shown to scale with the charge density of the ions and the experimental results are rationalized with respect to literature‐derived thermodynamic data, highlighting the ability of single entity electrochemistry to explore solvation in solvent mixtures.

Published: January 2022

AbstractThe rapidly expanding field of intelligent ion‐based devices has increased interest in the use of anodically‐coloring electrochromic nickel oxide thin films. The degradation and coloration mechanisms of nickel oxide, especially in Li+‐based electrolytes, are yet to be well understood. Herein we demonstrate that high potentials have a positive effect on the electrochromic performance of nickel oxide thin films. Our studies show that Cl− ions involved in the electrochromic process have been accumulated on the surface of the films upon extended electrochemical cycling, as confirmed by the X‐ray Photoelectron Spectroscopy. X‐ray Absorption Spectroscopy results indicate that the formation of Ni−Cl bonds influence the structural distortion and that the hybridization between Ni 3d and O 2p orbitals has been enhanced. Density functional theory calculations provide further insights for the band structures and how they change when Li+ and Cl− are adsorbed. Our results have revealed the underlying physical and chemical origins associated with the coloration mechanism and the degradation of nickel oxide thin films and highlighted the key role of Cl−. These new understandings will advance the development of superior electrochromic materials and the designing of efficient and durable electrochromic devices, both experimentally and theoretically.

Authors: Liang Min , Bian Bo , Yang Qing 
Published: January 2022

AbstractAimsPatients with heart failure (HF) have a poor prognosis and are categorized by ejection fraction. We performed a meta‐analysis to compare baseline characteristics and long‐term outcomes of patients with heart failure with reduced (HFrEF), mid‐range (HFmrEF), and preserved ejection fraction (HFpEF).Methods and ResultsA total of 27 prospective studies were included. Patients with HFpEF were older and had a higher proportion of females, hypertension, diabetes, and insufficient neuroendocrine antagonist treatments, while patients with HFrEF and HFmrEF had a higher prevalence of coronary heart disease and chronic kidney disease. After more than 1‐year of follow‐up, all‐cause mortality was significantly lower in patients with HFmrEF 9388/25 042 (37.49%) than those with HFrEF 39 333/90 023 (43.69%) and HFpEF 24 828/52 492 (47.30%) (p < .001). Cardiovascular mortality was lowest in patients with HFpEF 1130/9904 (11.41%), highest in patients with HFrEF 3419/16 277 (21.07%) mainly coming from HF death and sudden cardiac death, and middle in patients with HFmrEF 699/5171 (13.52%) and the non‐cardiovascular mortality was on the contrary. Subgroup analysis showed that in high‐risk patients with atrial fibrillation, the all‐cause mortality of HFpEF was significantly higher than both HFrEF and HFmrEF (p < .001). HF hospitalization was lowest in patients with HFmrEF 1822/5285 (34.47%), highest in patients with HFrEF 12 607/28 590 (44.10%) and middle in patients with HFpEF 8686/22 763 (38.16%) and the composite of all‐cause mortality and HF hospitalization was also observed similar results.ConclusionsIn summary, patients with HFmrEF had the lowest incidence of all‐cause mortality and HF hospitalization, while the highest all‐cause mortality and HF hospitalization rates were HFpEF and HFrEF patients, respectively.

Published: January 2022

AbstractPerovskite solar cells (PSCs), which have recently achieved more than 25% efficiency, are highly promising candidates for renewable energy generation. However, the interface of these solar cells is not yet fully understood. Herein, we used self‐assembled monolayers (SAMs) to regulate the interface of a SnO2 electron transport layer (ETL) and a common MAPbI3 perovskite absorber. Three different monolayers indicate that the contiguous terminal groups and charge distribution of their molecules influence interfacial properties and photovoltaic performance. Aligned energy levels, lower surface tension, and higher quality perovskite crystallization were obtained after SAM regulation. Consequently, applying a 4‐(trifluoromethyl) benzoic acid (BA‐CF3) SAM improved the power conversion efficiency (PCE) of the resulting PSC from 16.84% to 18.67%. Moreover, a high open‐circuit voltage (VOC) of 1.160 V was achieved with significantly reduced defects and non‐radiative recombination. This work highlights the regulation of these interfaces by a molecule for achieving high‐performance PSCs.
Variable dust charge generates a special type of nonlinear structures through modified Gardner equations
Authors: Ghosh Uday Narayan 
Published: January 2022

AbstractNonlinear damped modified Gardner equation is derived from the dust hydrodynamic model in dusty plasma, which is collisional, unmagnetized, and has two temperature ions. An extended version of the reductive perturbation technique (RPT) is used to derive the said equations. Approximate analytical solitary wave solution is obtained for compositional parameters near the critical composition. It is found that various nonlinear structures like super periodic, superhomoclinic, and special types of nonlinear structures are emerging while an investigation is done through the system of first‐order differential equations. The effects of different plasma parameters like collisions and dust charge variables on the wave structures have been noticed. In the circumstances of nebulas, interstellar clouds, planetary magnetospheres, and cometary environments recognized by astrophysicists, Voyager spacecraft observation on the fine structure of Saturn's rings, semiconductor devices, it has been investigated that the dust charge variable modifies the super nonlinear structures significantly.
