Published: July 2024

AbstractChiral organic–inorganic hybrid lead halides have recently attracted great attention due to their unique chirality and diverse functional properties. However, they suffer from highly toxic lead, while lead‐free chiral hybrid metal halides especially those with phase transitions remain sparse. Here, we report a new lead‐free chiral metal halide crystal [R‐3‐fluoropiperidinium]2SbCl5 ([R‐3‐FPP]2SbCl5), which crystalizes in chiral P212121 space group at 293 K and consists of chiral [3‐FPP]+ cations and one‐dimensional [SbCl5]n2− zigzag chains of corner‐sharing SbCl6 octahedrons. Notably, [R‐3‐FPP]2SbCl5 undergoes an above room temperature phase transition at 313 K, which can be attributed to the order‐disorder transition of both the organic [R‐3‐FPP]+ cation and inorganic [SbCl5]2− anions. In addition, [R‐3‐FPP]2SbCl5 also shows a broad band gap of 3.21 eV. This work promotes the exploration of chiral lead‐free hybrid lead halides with phase transitions.
Displacement prediction equations for seismic design of single friction pendulum base‐isolated structures
Authors: da Silva Andréia Horta Alvares , Pohl Diego Pizarro , Stojadinović Božidar 
Published: July 2024

AbstractWe propose a set of equations for preliminary risk‐targeted seismic design of structures base‐isolated using single friction pendulum (SFP) bearings. The equations offer statistical estimates of the maximum displacement of the superstructure relative to the base and the maximum displacement of the isolated base response quantities of interest (RQIs), given ground motion intensity measures and the essential dynamic properties of the SFP bearing base‐isolated structure. The set of proposed equations enables preliminary seismic design of SFP base‐isolated structures using the mean annual frequency of exceeding displacement‐defined limit states related to the two RQIs. To develop the design equations, we define and use a two‐degree‐of‐freedom (2DOF) surrogate model that features a few essential dynamic parameters of the SFP bearing base‐isolated structure. We first verify that the 2DOF surrogate model is accurate enough to represent the base and superstructure displacements compared to the complete multiple‐degree‐of‐freedom model of the prototype SFP bearing base‐isolated structure. Next, we perform more than 5 million non‐linear dynamical analyses of 4900 distinct 2DOF surrogates subjected to 210 different recorded ground motions scaled five times. We fit the response data of each 2DOF surrogate to a linear model and use two different modeling techniques to derive the design equations. One model is based on Polynomial Chaos Expansion (PCE), and the other model is based on Linear Regression (LR). The PCE model is more accurate than the LR model, with the trade‐off regarding its simplicity. Nevertheless, both the PCE and the LR models are accurate enough to estimate the design quantities of interest of the SFP bearing base‐isolated structure for preliminary design purposes. Lastly, we exemplify the use of the proposed design equations and we show that the estimate of base displacement is conservative in the cases when the superstructure of the SPF bearing base‐isolated structure yields.

Published: July 2024

AbstractChanging the soil and underlying surface conditions is a key practice for realizing irrigation on‐site storage and infiltration. However, biochar addition and grass planting effects on soil infiltration and water retention capacity remain unclear. The effects of 0% biochar (C1), 1% biochar (C3), 2% biochar (C4), 3% biochar (C5) under ryegrass and 0% biochar (C2), 1% biochar (C6), 2% biochar (C7) and 3% biochar (C8) under Festuca arundinacea on infiltration behaviours were modelled by using sandy loessial soil columns with ‘bare soil + 0% biochar’ as the control (CK). (i) There is a linear relationship between cumulative infiltration and CK–C8 treatment wetting fronts (R2 ≥ 0.982), which showed an initial rising trend and then tended to gradual, and the influence of different treatments was primarily reflected in the middle and late infiltration stages. (ii) Both biochar and grass planting decreased the soil infiltration capacity compared with that of the CK treatment. A high biochar addition rate was beneficial for inhibiting soil water infiltration and improving water retention ability in sandy loessial soil, however, ryegrass soil infiltrabilities under 1%, 2% and 3% biochar were all stronger than that of F. arundinacea. (iii) The cumulative infiltration fitting effects in different treatments with the Kostiakov, Kostiakov–Lewis, Philip, USDA–NRCS, Horton and Green–Ampt equations were all good, although there were some differences in the infiltration rate curves under the six different fitting equations. This study is helpful in understanding effective sandy loessial soil storage ability for irrigation and efficient water resource usage.

Authors: AL‐Daamee Fatimah Q. , Hamza Naseer H. 
Published: July 2024

AbstractPrevious works that investigated the characteristics of heat transfer and fluid flow in channels with corrugated walls have been extensively reviewed in this study. In accordance with the fast increase in power consumption requirements, many researchers have investigated a new approach for cooling techniques that can enhance the cooling performance of devices without consuming more power. To improve the efficiency of energy systems, many investigators and engineers implement promising techniques such as surface optimization and additives as passive methods to augment the rates of heat transfer. Researchers investigated different corrugation profiles along with various working fluids as well as external power devices to further improve the heat exchange process of thermal systems. The aim of this article is to give a clear preview of the effects of different parameters such as wave parameters, Reynolds number, type of working fluid, and pulsating flow condition on the average and local Nusselt number, the pressure drop, the performance factors, and irreversibility. The main findings are listed in tables and depicted in figures, the matter that helps engineers and researchers to choose a suitable channel shape for their applications.

AbstractThe morphology of plated lithium (MPL) metal on graphite anodes, traditionally described as “moss‐like” and “dendrite‐like”, exert a substantial negative influence on the performance of lithium‐ion batteries (LIBs) by modulating the metal‐electrolyte interface and side reaction rates. However, a systematic and quantitative analysis of MPL is lacking, impeding effective evaluation and manipulation of this detrimental issue. In this study, we transition from a qualitative analysis to a quantitative one by conducting a detailed examination of the MPL. Our findings reveal that slender lithium dendrites reduces the lifespan and safety of LIB by increasing the side reaction rates and promoting the formation of dead lithium. To further evaluate the extent of the detrimental effect of MPL, we propose the specific surface area (SSA) as a critical metric, and develop an in situ method integrating expansion force and electrochemical impedance spectroscopy to estimate SSA. Finally, we introduce a pulse current protocol to manipulate hazardous MLP. Phase field model simulations and experiments demonstrate that this protocol significantly enhances the reversibility of plated lithium. This research offers a novel morphological perspective on lithium plating, providing a more detailed fundamental understanding that facilitates effective evaluation and manipulation of plated lithium, thereby enhancing the safety and extending the cycle life of LIBs.image
Pig manure degradation and carbon emission: Measuring and modeling combined aerobic–anaerobic transformations

Published: July 2024

AbstractGreenhouse gas emissions from liquid livestock manure storage significantly contribute to global warming. Accurate farm‐scale models are essential for predicting these emissions and evaluating manure management strategies, but they rely on multiple parameters describing carbon loss dynamics. Surface respiration may significantly influence carbon loss and methane emission, yet it is not explicitly included in current models. We conducted experiments to measure pig manure surface respiration rate and its effect on organic matter degradation and methane and carbon dioxide emissions. Manure was incubated for 283 days at 10°C or 20°C under aerobic or anaerobic conditions, while measuring methane and carbon dioxide emission. This was followed by anaerobic digestion at 38°C. Surface respiration reduced the organic matter content, and the effect was temperature dependent. Methane emission was not affected by surface respiration, suggesting that substrate availability was not rate‐limiting for methanogenesis. Surface respiration rates were 18.1 ± 3.5 g CO2 m−2 day−1 at 10°C and 37.1 ± 13.1 g CO2 m−2 day−1 at 20°C (mean ± standard deviation) and were consistent with microsensor measurements of oxygen consumption in different manure surfaces. Based on these results, temperature‐ and surface area‐dependent respiration was incorporated in the existing anaerobic biodegradation model (ABM). Simulations showed that surface respiration accounts for 29% of carbon losses in a typical pig house and 8% for outdoor storage. Developing and refining algorithms for diverse carbon transformations, such as surface respiration, is crucial for evaluating the potential for methane emission and identification of variables that control emissions at the farm scale.

AbstractWe respond to discussant comments on our paper “Twenty years of network meta‐analysis: Continuing controversies and recent developments” (https://doi.org/10.1002/jrsm.1700) and raise some additional points for consideration, including: the way in which methodological guidance is generated; integration of the estimand framework with evidence synthesis; and implications of the European Joint Clinical Assessment. We ask: what properties are required of population adjustment methods to enable transparent and consistent decision‐making? We also ask why individual patient data is not routinely made available to re‐imbursement authorities and clinical guideline developers.

Published: July 2024

AbstractInteractions between service employees and customers at check‐in shape customers' first impressions and lead to their future behavioral intentions. Even though customer relationship management (CRM) relies heavily on the hospitality check‐in experience, research is scarce on its impacts and the moderating effect of loyalty membership programs. Based on the broaden‐and‐build theory, the current study examined customer check‐in significance associated with their outcomes and compared two groups to determine if loyalty programs have a meaningful impact. The findings confirmed the importance of the check‐in experience and the moderating effect of loyalty membership was significantly related to customers' perceptions.
Barriers to adoption of slow tourism: An innovation resistance theory perspective
Authors: Chauhan Vishakha 
Published: July 2024

AbstractSlow tourism is a recent concept in the travel and tourism industry. It offers rejuvenation and immersion in local culture to travelers along with environmental and economic benefits. While slow tourist destinations are picking up the pace and interest of consumers, they also face a lot of resistance from consumers. However, existing literature on slow tourism has essentially focused on travelers' adoption intentions and motivations toward slow tourism, scarcely investigating the sources of such resistance. Addressing this pertinent gap, this study applies the innovation resistance theory (IRT) to examine the barriers to consumer adoption intention toward slow tourism. A mixed‐method research approach with in‐depth discussions with slow travelers and a large‐scale cross‐sectional survey of 350 travelers from India is used to test the proposed model. Findings advocate that the usage and image barriers are the prime inhibitors of slow tourism adoption. As a moderator, consumers' environmental concern and an individualistic culture dampens the strength of the association between the barriers and slow tourism adoption intentions. Results present important ramifications for slow tourism marketers and researchers.
Herders' risk preference and grassland transfer strategy: Evidence from a field experiment in pastoral areas of China
Authors: Guan Shiqi , Tang Zeng , Zhao Menglin , Li Yiwen 
Published: July 2024

AbstractEncouraging and guiding herders to participate in grassland transfer promotes the high‐quality development of grassland animal husbandry. We conducted a survey among 356 herders from Qinghai and Gansu provinces in China, to explore the impact of herders' risk preference and perceptions on their grassland transfer strategies. We used experimental economics methods to measure the risk preferences of herders. Our results indicate that the majority of herders exhibit risk‐averse attitudes. A theoretical model was used to establish hypotheses on the relationship between risk preference and grassland transfer decision‐making. The double‐hurdle model and moderating effect model were used to test these hypotheses. Our analysis shows that herders' risk preferences have a significant negative effect on their decisions to engage in grassland transfer. Both risk preferences and risk perception have a significant impact on grassland transfer‐in decisions, but no significant impact on grassland transfer‐out. A heterogeneity analysis revealed that the impact of risk preferences on grassland transfer participation is more pronounced among herders in Qinghai compared to those in Gansu. Moreover, we found that risk perception plays a moderating role on the influence of risk preferences on decisions regarding grassland transfer. These findings are crucial to formulate strategies for the sustainable management of the grassland transfer market.

AbstractBackgroundThere is an increased risk of venous thromboembolism (VTE) among neonates due to their unique hemostatic system. However, there is lack of approved treatment options for VTE in neonatal population. Importantly, dalteparin, a low molecular weight heparin approved for pediatric VTE in children ≥1 month of age, has also been used for the treatment of neonatal VTE. Based on the request from the Food and Drug Administration, this retrospective study aimed to characterize the safety, clinical effects, and dosing of dalteparin for treatment of VTE among neonates.ProcedureData from electronic medical records for neonates (born ≥35 weeks of gestation) treated with dalteparin for VTE between January 2010 and December 2021 were collected. The data assessed included bleeding and deterioration in hematological biomarkers among other adverse events, changes in relevant factor antifactor Xa (anti‐Xa) levels and VTE status, and dosing of dalteparin and corresponding anti‐Xa assay levels.ResultsSixteen neonates from five participating sites in the United Kingdom were included. There were no bleeding events or deaths. Only one serious adverse event of hypoglycemic brain injury (unrelated to dalteparin) was documented in a patient with a history of hyperinsulinism. Median (range) daily dose of dalteparin at initiation was 309 (297–314) IU/kg. Eight of 16 neonates achieved therapeutic anti‐Xa level, including two patients who did so after the first dose.ConclusionsDalteparin treatment in neonates raised no major safety concerns. Larger cohort studies may help provide further insights on clinical effects of dalteparin for neonatal VTE.

AbstractBackgroundComprehensive guidelines for the management of iron deficiency anemia (IDA) in adolescents with heavy menstrual bleeding (HMB) presenting to the emergency department (ED) are lacking, leading to variability in care. We aimed to standardize the evaluation and management of these patients through the development and implementation of an evidence‐based algorithm using quality improvement methodology.MethodsBaseline data of the target population identified variability across four key measures of clinical management: therapy choice and administration, laboratory evaluation, hematology service consultation, and patient disposition. Literature review and consensus from pediatric hematology and gynecology providers informed a draft algorithm that was refined in an iterative multidisciplinary process. From December 2022 to July 2023, we aimed to achieve a 25% relative increase in patients to receive optimal management per the algorithm, while using sequential Plan–Do–Study–Act (PDSA) cycles. Process measures focusing on provider documentation and balancing measures, such as ED length of stay, were assessed concurrently.ResultsForty‐nine patients were evaluated during four PDSA cycles. Improvement of ≥40% above baseline regarding recommended therapy administration was achieved across four PDSA cycles. Adherence to recommended therapy choice improved from 57% (baseline) to 100%, minimal laboratory evaluation from 14% to 83%, hematology consultation from 36% to 100%, and appropriate disposition from 71% to 100%. ED length of stay remained stable.ConclusionImplementation of a standardized algorithm for management of IDA secondary to HMB in adolescents in the ED increased adherence to evidence‐based patient care.

Published: July 2024

AbstractThe surface of carbon fiber is treated with sizing agent containing hydroxylated carbon nanotubes, fullerenols, and graphene oxide, respectively. The effects of carbon nanomaterials and their structures on the surface properties of carbon fiber, the interfacial properties and the mechanical properties of carbon fiber/epoxy composites are investigated. All three types of carbon nanomaterial can improve the interfacial bonding strength and modulus, thereby enhancing the interlaminar shear strength (ILSS) of composites. Moreover, the ILSS increases with the increase of interfacial bonding strength, due to the roughness and the number of active groups. Compared with the composite without carbon nanomaterials, the interfacial bonding strength of the three nanoparticle‐modified composites increased by 14%, 5% and 4%, the modulus increased by 10%, 26%, and 9%, and the ILSS increased by 14%, 8%, and 7%, respectively. The interfacial bonding strength has a more significant impact on the ILSS than the interfacial modulus.Highlights
CNTs, graphene oxide and fullerenols regulate the surface characteristics of carbon fibers.
The influence of carbon nanomaterials on the interfacial properties of composites.
The relationship between the fiber surface, the interface and the composites.
Amphiphilic ligand‐doped liquid crystal‐based detection of Hg2+ ions on polyimide surface with alkyl pendent groups

Published: July 2024

AbstractIn this study, amphiphilic thiosemicarbazone was used to align liquid crystal (4‐cyano‐4′‐pentylbiphenyl) in a homeotropic way on polyimide containing alkyl pendent groups (AHDPI), which was coated on a glass slide. The amphiphilic ligands 2‐(4‐(dodecyloxy)benzylid‐ene)hydrazine‐1‐carbothioamide (DT) and 2‐(1‐dodecyl‐2‐oxoindolin‐3‐ylidene)hydrazine‐1‐carbothioamide (IT) were doped with liquid crystal (LC) to develop LC‐based sensors to detect Hg2+ ions in water. The selective interaction of carbothioamide with Hg2+ ions triggered the orientation transition of LC from homeotropic to parallel alignment and gave dark to bright optical signal at the LC/aqueous interphase. Self‐immobilization of thiosemicarbazone‐based ligands on AHDPI‐coated glass slide can be used to detect Hg2+ ions with high sensitivity. The limit of detection with DT and IT was found to be 0.5 and 0.25 μmol L−1, respectively. Density functional studies were carried out to study the interaction of the thiosemicarbazone ligands with mercuric ions, resulting in highly negative binding energies of −1.55 and −2.06 eV for DT and IT with Hg2+ ions, respectively. The chemical and thermal stability (up to 268 °C) of the AHDPI coated on glass slide made it reusable at least twice for sensor fabrication. This provides a quicker and cheaper alternative to traditional methods of sensor fabrication. © 2024 Society of Chemical Industry.
