Hierarchical Porous Carbon Embedded MoSe2 Effectively Improve Cycle Stability in K‐Se Battery
Authors: Yang Wenting , Jamil Sidra , Xu Maowen 
Published: June 2023

AbstractIt is a crucial challenge to control the dissolution and diffusion of polyselenides in the K−Se system. Herein, a polar material MoSe2 was introduced into Chitosan‐derived hierarchical porous carbon (MoSe2‐HPC) for the first time by a simple freeze‐dried carbonization method, which was used as host materials of Se. The porous carbon plays a vital role in alleviating volume expansion from Se to K2Se and affording physical restriction effect for generating potassium polyselenides (KPSs). The adsorption experiment can prove that the additive MoSe2 as active site can effectively anchor soluble KPSs by remarkable polar interaction to achieve raising electrochemistry performance. Therefore, the Se@MoSe2‐HPC cathode presents superior cycling stability with a specific capacity of 323.2 mAh g−1 after 500 cycles at 1 C and satisfactory rate performance of 261.7 mAh g−1 at 5 C, demonstrating the great potential of MoSe2 as polar adsorption component for K−Se batteries cathode materials.

Published: June 2023

AbstractThe present study investigates the chlorination and migration mechanism of Tobermorite9 Å through the use of density functional theory (DFT) calculation and ab initio molecular dynamics (AIMD). The findings reveal a negative adsorption energy value of −2.19488 eV. The results of the charge density difference analysis reveal that the Ca atoms experience electron loss, while the Cl atom undergoes electron gain. The O atom situated at the end of the silicate chain (and silicate chain bridge) exhibits electron gain, and the Na atom experiences electron loss. The results of density of states (DOS) and partial density of states (PDOS) demonstrate that the Ca−Cl bond was created as a result of the interaction between Ca and Cl orbitals. The evident overlaps between Na‐p and O24‐p orbitals lead to the formation of Na−O bond. In AIMD simulation, the minimum energy barrier and activation energy of sodium chloride molecule are 0.09236 eV and 0.059 eV, respectively. The findings also suggest that chloride ion diffusion is facile on hydrated calcium silicate.
Discovery, discernment, and exploitation: Entrepreneurial mechanisms at the nexus of individual and opportunity

AbstractResearch SummaryExtending the opportunity‐discovery perspective on Kirznerian entrepreneurship, we propose a general framework in which new businesses emerge from three distinct mechanisms situated at the individual‐opportunity nexus: discovery, discernment, and exploitation. We propose observing opportunities in market exchanges and characterizing their profitability potential based on a component that is common to all observers and one that is specific to individual observers who vary in access to market information. Analysis of an online platform for freelance labor demonstrates our contributions in theory, measurement, and inference. In this context, discovery and exploitation mechanisms shape individuals' entrepreneurial transitions from freelancer to founder. We discuss applications of our framework across settings, extensions to other types of entrepreneurship, and the viability of opportunity as an orienting construct for entrepreneurship research.Managerial SummaryEntrepreneurial opportunities are present in all markets but there is no systematic way of observing or valuing such opportunities, much less predicting where and when they become the basis for new businesses. We propose doing this with data commonly collected and archived by online platforms. We acknowledge that new businesses are often founded if one is in the right place at the right time; if one can distinguish a great opportunity from a good (or bad) one; or if one is capable of making a market. Our framework makes each of these intuitions empirically distinct, thus offering insights on where, when, and by whom new businesses are likely to be founded.

AbstractThe tumor microenvironment typically possesses immunosuppressive properties that hinder the effectiveness of antitumor immune responses, even in the context of immunotherapies. However, it is observed that pathogenic microorganisms can trigger strong immune responses during infection, offering a potential means to counteract the immunosuppressive environment of tumors. In this study, a protein nanocage called CpG@HBc nanocages (NCs) is developed, which mimics the structure of the hepatitis B virus and combines with an immunostimulatory component known as cytosine phosphoguanosine oligonucleotide (CpG). By delivering these immunostimulatory agents, CpG@HBc NCs are able to effectively reverse the suppressive tumor microenvironment, resulting in the inhibition of poorly immunogenic tumors in mice. Through high‐dimensional mass cytometry (CyTOF) analysis, remarkable alterations in immune responses is observed induced by CpG@HBc. Treatment with immunogenic CpG@HBc NCs, along with co‐injection of an OX40 agonist, sensitized colorectal cancer tumors to T cell immune responses, resulting in significant impairment of tumor growth and robust immune activation. Furthermore, CpG@HBc NCs induced long‐term antitumor immunological memory, protecting tumor‐cured mice from tumor rechallenge. Overall, these findings highlight the potential of a virus‐inspired protein nanocage to mimic anti‐viral immunity and offer a unique therapeutic approach for cancer immunotherapy.

AbstractSodium‐ion batteries (SIBs) are a possible candidate to create safe, sustainable, and cost‐effective batteries. Solid sodium‐ion conducting organically modified ionogel electrolytes are investigated. Silica‐based ionogels typically consist of an ionic liquid electrolyte (ILE) confined within a silica matrix and possess high thermal stability, good ionic conductivity, safety, and good electrochemical stability. However, they readily deteriorate when stress is applied, decreasing the electrolyte's and battery's overall performance. The mechanical characteristics of silica can be improved using organic moieties, creating Ormosils®. Silica‐based ionogels with phenyl‐modified silanes improve the mechanical characteristics by a reduction of their Young's modulus (from 29 to 6 MPa). This is beneficial to the charge‐transfer resistance, which decreases after implementing the electrolyte in half cells, demonstrating the improved interfacial contact. Most importantly, the phenyl groups change the interacting species at the silica interface. Cationic imidazolium species pi‐stacked to the phenyl groups of the silica matrix, pushing the anions to the bulk of the ILE, which affects the ionic conductivity and electrochemical stability, and might affect the quality of the SEI in half cells. In essence, the work at hand can be used as a directory to improve mechanical characteristics and modify and control functional properties of ionogel electrolytes.

AbstractOwing to rapid property degradation after ambient exposure and incompatibility with conventional device fabrication process, electrical transport measurements on air‐sensitive 2D materials have always been a big issue. Here, for the first time, a facile one‐step polymer‐encapsulated electrode transfer (PEET) method applicable for fragile 2D materials is developed, which showed great advantages of damage‐free electrodes patterning and in situ polymer encapsulation preventing from H2O/O2 exposure during the whole electrical measurements process. The ultrathin SmTe2 metals grown by chemical vapor deposition (CVD) are chosen as the prototypical air‐sensitive 2D crystals for their poor air‐stability, which will become highly insulating when fabricated by conventional lithographic techniques. Nevertheless, the intrinsic electrical properties of CVD‐grown SmTe2 nanosheets can be readily investigated by the PEET method instead, showing ultralow contact resistance and high signal/noise ratio. The PEET method can be applicable to other fragile ultrathin magnetic materials, such as (Mn,Cr)Te, to investigate their intrinsic electrical/magnetic properties.

AbstractEubrachyurans, or ‘higher’ true crabs, are the most speciose group of decapod crustaceans and have a rich fossil record extending into the Early Cretaceous. However, most extant families are first found in the fossil record in the Palaeogene, and particularly in the Eocene. Unfortunately, fossils of many early eubrachyuran groups are often fragmentary, and only a few studies have combined extinct and extant taxa in a phylogenetic context using different optimality criteria. Here, we report the dairoidid crab Phrynolambrus sagittalis sp. nov., an enigmatic eubrachyuran from the upper Eocene of Huesca (northern Spain), whose completeness and exquisite preservation permit examination of its anatomy in a phylogenetic context. Dairoidids have previously been considered among the oldest stone crabs (Eriphioidea) or elbow crabs (Parthenopoidea), two disparate and distantly related groups of true crabs living today. Mechanical preparation and computed tomography of the fossil material revealed several diagnostic features that allow a detailed comparison with families across the crab tree of life, and test hypotheses about its phylogenetic affinities. Phrynolambrus sagittalis is the first record of the genus in the Iberian Peninsula, and represents one of the oldest crown parthenopoidean crabs worldwide, expanding our knowledge of the biogeographical distribution of elbow crabs during the Palaeogene, as well as their early origins, anatomical diversity and systematic affinities. Understanding the disparity of Eocene eubrachyurans is pivotal to disentangling the systematic relationships among crown families, and interpreting the spatio‐temporal patterns leading to the evolution of modern faunas.

AbstractAddiction is a global concern with a high relapse rate and without effective therapeutic options. Developing new effective therapeutic strategies is impossible without discovering the disease's neurobiological basis. The present systematic review aimed to comprehensively recognize and discuss the role of local field potentials from brain areas essential in forming and storing context‐drug/food associations following the conditioned place preference (CPP) paradigm as a popular animal model of reward and addiction. Qualified studies were incorporated by a broad search of four databases, including Web of Science, Medline/PubMed, Embase, and ScienceDirect, in July 2022, and they were evaluated via appropriate methodological quality assessment tools. The current study found that drug‐seeking behavior in different stages of the CPP paradigm is accompanied by alterations in neural oscillatory activity and adaptations in connectivity among various areas such as the hippocampus, nucleus accumbens, basolateral amygdala, and prelimbic area, intensely engaged in reward‐related behaviors. These findings need to be extended by more future advanced studies to finally recognize the altered oscillatory activity patterns of large groups of cells in regions involved in reward‐context associations to improve clinical strategies such as neuromodulation approaches to modify the abnormal electrical activity of these critical brain regions and their connections for treating addiction and preventing drug/food relapse in abstinent patients.Definitions
Power is the amount of energy in a frequency band and is the squared amplitude of the oscillation.
Cross‐frequency coupling refers to a statistical relationship between activities in two different frequency bands.
Phase‐amplitude coupling is perhaps the most commonly used method of computing cross‐frequency coupling. Phase‐amplitude coupling involves testing for a relationship between the phase of one frequency band and the power of another, typically relatively higher, frequency band. Thus, within phase‐amplitude coupling, you refer to the “frequency for phase” and the “frequency for power.”
Spectral coherence has been frequently used to detect and quantify coupling between oscillatory signals of two or more brain areas. Spectral coherence estimates the linear phase‐consistency between two frequency‐decomposed signals over time windows (or trials).

Authors: Mishra Deepti , Mishra Alok , Abdalhamid Samia 
Published: June 2023

AbstractThis study provides empirical evidence to the body of knowledge in Agile methods adoption in small, medium, and large organizations in the global context. This research explores facilitators and inhibitors of Agile methods adoption in software development organizations. A survey was conducted among Agile professionals to gather survey data from 52 software organizations in seven countries across the world. This study found many facilitators of Agile adoption to be significant such as customers’ dominant issues, encouragement, project champion, highly competent team, use of tools, etc. Similarly a correlation analysis revealed multiple inhibitors as significant: absence of a full set of right Agile practices, absence of customer presence, absence of tracking mechanisms during Agile progress, and failure to determine the role of the client. The present study identifies that an Agile team with high expertise and competence leads to higher quality in software, customer satisfaction along with return on investment (ROI) while a small Agile team increases ease in handling changing requirements, customer satisfaction, reduced delivery time, and increased ROI. Frequent delivery accelerates better control over work, adds to software quality, customer satisfaction, and in shortening delivery time along with increase ROI. It has also been observed that providing essential features early leads to increase in software quality and customer satisfaction. This study confirms that active customer focus leads to better control over work. Further, absence of customer decreases dealing with changing requirements, and customer satisfaction while absence of progress tracking lowers customer satisfaction.
Study of the unified strength theory for seismic response of frame building on loess considering soil‐structure interaction
Authors: Xiong Zhongming , Lin Leyi , Sun Qiren , Chen Xuan 
Published: June 2023

SummaryTo investigate the effect of soil‐structure interaction (SSI) on the seismic response of frame buildings on collapsible loess, the secondary development of Abaqus was used to realize the embedding of the unified strength theory constitutive model. Meanwhile, a new nonlinear elastic model generated by the unified strength theory (b, the failure criterion parameter in the unified strength theory, equals 0.5) was developed. Seven‐ and nine‐story frame buildings were selected as engineering examples in this study. The outcomes indicate that the nonlinear behavior of the loess–pile has a significant effect on the dynamic interaction of both group pile foundations and the superstructure under strong earthquakes. This results in an amplification of the displacement response and a reduction in inter‐story shear force. As the foundation soil becomes softer, the K‐type distribution of both peak accelerations and inter‐story displacements along height becomes more obvious in general.

Published: June 2023

AbstractOrganophosphate pesticides (OPs), which are among the most widely used synthetic chemicals for the control of a wide variety of pests, are however associated with various adverse reactions in animals and humans. Chlorpyrifos, an OP, has been shown to cause various health complications due to ingestion, inhalation, or skin absorption. The mechanisms underlying the adverse effect of chlorpyrifos on neurotoxicity have not been elucidated. Therefore, we aimed to determine the mechanism of chlorpyrifos‐induced cytotoxicity and to examine whether the antioxidant vitamin E (VE) ameliorated these cytotoxic effects using DBTRG‐05MG, a human glioblastoma cell line. The DBTRG‐05MG cells were treated with chlorpyrifos, VE, or chlorpyrifos plus VE and compared with the untreated control cells. Chlorpyrifos induced a significant decrease in cell viability and caused morphological changes in treated cultures. Furthermore, chlorpyrifos led to the increased production of reactive oxygen species (ROS) accompanied by a decrease in the level of reduced glutathione. Additionally, chlorpyrifos induced apoptosis by upregulating the protein levels of Bax and cleaved caspase‐9/caspase‐3 and by downregulating the protein levels of Bcl‐2. Moreover, chlorpyrifos modulated the antioxidant response by increasing the protein levels of Nrf2, HO‐1, and NQO1. However, VE reversed the cytotoxicity and oxidative stress induced by chlorpyrifos treatment in DBTRG‐05MG cells. Overall, these findings suggest that chlorpyrifos causes cytotoxicity through oxidative stress, a process that may play an important role in the development of chlorpyrifos‐associated glioblastoma.

ABSTRACTObjectiveTo develop a prediction model for the development of hypertension in the decade following pre‐eclampsia in women who were normotensive shortly after pregnancy.MethodsThis was a longitudinal cohort study of formerly pre‐eclamptic women attending a university hospital in The Netherlands between 1996 and 2019. We developed a prediction model for incident hypertension using multivariable logistic regression analysis. The model was validated internally using bootstrapping techniques.ResultsOf 259 women, 185 (71%) were normotensive at the first cardiovascular assessment, at a median of 10 (interquartile range (IQR), 6–24) months after a pre‐eclamptic pregnancy, of whom 49 (26%) had developed hypertension by the second visit, at a median of 11 (IQR, 6–14) years postpartum. The prediction model, based on birth‐weight centile, mean arterial pressure, total cholesterol, left ventricular mass index and left ventricular ejection fraction, had good‐to‐excellent discriminative ability, with an area under the receiver‐operating‐characteristics curve (AUC) of 0.82 (95% CI, 0.75–0.89) and an optimism‐corrected AUC of 0.80. The sensitivity and specificity of our model to predict hypertension were 98% and 34%, respectively, and positive and negative predictive values were 35% and 98%, respectively.ConclusionsBased on five variables, we developed a good‐to‐excellent predictive tool to identify incident hypertension following pre‐eclampsia in women who were normotensive shortly after pregnancy. After external validation, this model could have considerable clinical utility in tackling the cardiovascular legacy of pre‐eclampsia. © 2023 The Authors.

AbstractIn this work, betaine (trimethyl glycine) and tannin (complex biomolecules of polyphenolic nature) were used as bio‐fillers. Urea‐formaldehyde (UF) resin with a molar ratio of formaldehyde versus urea (FA/U) of 0.8 was synthesized in situ with tannin and betaine as bio‐fillers, to obtain UF resin with reduced free FA content and increased hydrolytic and thermal stability by the principles of sustainability. The samples TUF (with tannin) and BUF (with betaine) were characterized by using X‐ray diffraction analysis (XRD), non‐isothermal thermogravimetric analysis (TGA), and differential thermal analysis (DTA), supported by data from Fourier Transform Infrared spectroscopy (FTIR) and Scanning electron microscopy (SEM). The percentage of free FA in modified BUF resin is 0.1%, while the percentage of free FA in tannin‐modified resin is 0.8%. The hydrolytic stability of the modified UF resins was determined by measuring the concentration of liberated FA in the modified UF resins, after acid hydrolysis. The modified BUF resin is hydrolytically more stable because the content of released FA is 3.6% compared to the modified TUF resin, where it was 7.4%. Based on the value for T5%, the more thermally stable resin is the modified TUF resin (T5% = 123.1°C), while the value of the T5% for the BUF resin is 83.1°C. This work showed how UF bio‐composite with reduced free FA content and increased hydrolytic and thermal stability can be obtained using tannin and betaine as bio‐fillers.
