Published: November 2024

ABSTRACTThis study aimed to improve the surface of polymer implants by examining the physicochemical and biological properties of UHMWPE coated with titanium, tantalum, and zirconium thin films. The coatings exhibited enhancements in wettability alongside diminished roughness. The Zr film exhibited a contact angle of 16°, a significant improvement compared to the UHMWPE sample, which has an angle of 102°. Moreover, the roughness of the pristine sample (0.958 μm) was substantially reduced to 0.403 μm with the Ta film. These characteristics prevented the adhesion of fibroblasts, minimizing the risk of fibrous encapsulation surrounding the implant [2]. Micro‐abrasion tests demonstrated that the coatings reduced the wear coefficient, making them ideal for increasing the longevity of the implant in the human body. Transitioning from a wear coefficient of 0.47 × 10–12 m2/N for UHMWPE, values as low as 0.21 × 10–12 m2/N were attained, particularly in the sample with the Ti film. Therefore, the coatings exhibit favorable characteristics for the intended biomedical application.

AbstractDonor‐acceptor in linear π‐conjugated systems elicits the intramolecular charge transfer which improves the optical and electronic characteristics. Nevertheless, linear arrangement of electron donor and acceptor finely tune the charge or electron transfer process divulges the device performance. Therefore, molecular engineering of appropriate D−A with precise spacer is indeed challenging. Herein, we synthesized two bispyrene derivatives and attached with benzothiadazole and phenyl group through imidazole spacer (PyBTD and PyBz). PyBTD has shown solvatochromism demonstrates the intramolecular charge transfer (ICT) from pyrene to benzothiadiazole while PyBz remains as pristine spectra. Microscopic images reveal that network‐type structures for PyBTD and elongated nanorods from self‐assemblies of PyBz. Subsequently, host‐guest interactions suggest that C60 was encapsulated in concave shaped bispyrene controls their crystallinity in nanostructures leads short nanosheets. Impedance analyses depict ICT assisted nanowires facilitate improved conductivity than host‐guest complex. Therefore, imidazole spacer between D−A systems paves the way to design such type of molecules for future generated optoelectronics.

Published: November 2024

AbstractSupramolecular polymers (SPs) formed via the stacking of π‐conjugated molecules are attractive nanomaterials because of their potential optoelectronic properties derived from the non‐covalent interaction between the π‐skeletons. Especially, SPs possessing naphthalenediimide (NDI) core units can act as superior electron acceptors due to their deep lowest unoccupied molecular orbital (LUMO). Interaction of such SP with electron donors can realize a charge transfer system, but this has not been established. Herein, we report a photoinduced electron transfer system from cesium lead bromide quantum dot (QD) as an electron donor to SP composed of cholesterol‐functionalized NDI derivatives. The supramolecular polymerization in a non‐polar solvent was analyzed in detail via microscopic and spectroscopic analyses. Upon mixing the SP with QDs, the photoluminescence intensity and lifetime of QDs decreased significantly, indicating efficient photoinduced electron transfer from QD to SP.

Published: November 2024

AbstractIn this study, the linear and non‐linear multivariate relationships between 25 teleconnection indices (tele‐indices) as independent variables and annual P24max as the dependent variable were analyzed using multivariate linear regression (MLR) and decision tree regression models (M5), in selected synoptic weather stations of Iran over a statistical period of 30 years (1992–2021). No strong and statistically significant correlation between each tele‐index and P24max was observed. Therefore, it is not appropriate to attribute climate changes in the region to a single factor such as El Niño, but rather consider the combined influence of multiple factors. The M5 model demonstrated higher performance, indicating a non‐linear relationship between tele‐indices and P24max. The stepwise execution of the M5 model tree showed that the algorithm follows a greedy approach, and it is not necessary to use all variables to predict P24max. The normalized root mean square error (NRMSE) of P24max estimation was found to be 15%, 13%, 15%, 8%, 20%, 14%, and 12% with the coefficients of determination of 0.78, 0.79, 0.72, 0.85, 0.81, 0.82, and 0.84 in Hashemabad‐Gorgan, Rasht, Kermanshah, Ahvaz, Bandar Abbas, Isfahan, and Birjand, respectively. Finally, it is possible to forecast P24max using tele‐indices measured in the previous year.
Highly Significant Detection of X‐Ray Polarization in Sco X‐1 and Its Polarization Angle Misaligned With the Direction of the Radio Jet
Authors: La Monaca Fabio ,   IXPE Science Team
Published: November 2024

ABSTRACTThe Imaging X‐ray Polarimetry Explorer has successfully measured the X‐ray polarization of Scorpius X‐1, the brightest Z‐source, in the 2–8 keV energy band. The degree of polarization was found to be with a polarization angle of °. This measurement was conducted simultaneously with NICER, NuSTAR, and Insight‐HXMT observations, enabling a detailed analysis of the source's broad‐band spectrum across soft and hard X‐rays. The source was observed for the majority of the time in its soft state, with occasional flaring. Furthermore, low‐frequency quasiperiodic oscillations were observed. Through a spectro‐polarimetric analysis, we determined that the accretion disk exhibits a polarization <3.2% (90% CL) and the Comptonized component at higher energy a polarization of . An attempt was also performed to measure the polarization of the reflection component. Moreover, a rotation in X‐ray polarization is observed compared to previous observations by OSO‐8 and PolarLight, as well as with respect to the position angle of the radio jet. This finding suggests that the polarization may vary with the state of the source, which means a change in the geometry of the corona with the accretion flow or potentially indicating a relativistic precession.
The Impact of Green Market Orientation and Ambidextrous Green Innovation on Organizational Performance: Empirical Study on Small Restaurants in Vietnam
Authors: Ngo Quang‐Huy 
Published: November 2024

ABSTRACTThe natural resource‐based view (NRBV) posits that aligning business operations toward sustainability fosters innovation and leads to sustainable competitive advantages. Green market orientation (GMO) and green innovation (GI) have emerged as strategic approaches that enhance organizational performance (OP). However, understanding service contexts still needs to be improved, particularly in small restaurants in emerging countries. Additionally, while previous studies on GMO and GI have primarily focused on operationalizing OP based on past performance, there needs to be more understanding of their impact on past performance and future growth. Utilizing a balanced scorecard approach helps to address this limitation effectively. Building on these theoretical frameworks, this study investigates the impact of GMO and ambidextrous GI on OP and the mediating role of ambidextrous GI in the GMO‐OP linkage. Data from 272 small restaurants in Vietnam were collected and analyzed using PLS‐SEM to illuminate the effects of GMO in the restaurant context. The findings support both direct and indirect effects. This study advances NRBV by utilizing balanced scorecard approaches to capture performance outcomes comprehensively. This research also extends GMO studies to the service sector, especially small restaurants, underscoring the pivotal roles of GMO in boosting GI and performance. Lastly, this study follows prior calls for more studies to shed light on the antecedents and consequences of ambidextrous GI.
Net‐zero policy and forward default risk in the energy sector: Evidence of corporate environmentalism using (a)symmetric models
Authors: Mushafiq Muhammad , Prusak Błażej , Apergis Nicholas 
Published: November 2024

AbstractThis study aims to examine the impact of the net‐zero policy on forward default risk at the firm level within the energy sector of the US, spanning over the period 2007–2021. The research employs Panel Vector Autoregression (PVAR) modeling, as well as linear and non‐linear Autoregressive Distributed Lag (ARDL) models to investigate this relationship. The findings suggest that the implementation of net‐zero policy measures can have complex effects on firms' default risk in both the short and long run. The PVAR results confirm a unidirectional negative impact of net‐zero policies on forward default risk over 2, 3, and 5 years. The symmetric ARDL model results show a negative long‐run impact on the future probability of default, with short‐run impacts being positive across all time horizons. The asymmetric ARDL model findings indicate that positive net‐zero measures reduce the probability of default in the long run and increase it in the short run across all time horizons. Conversely, negative shocks of net‐zero measures lead to an increase in the forward probability of default in the long run. The differences in findings between the long and short run are attributed to the effects of capital expenditures on infrastructure expenses required to achieve net‐zero results. This study contributes to the literature on financial outcomes and the impact of adopting sustainable development and net‐zero goals. The policy implications suggest that a supportive institutional framework must be provided to reduce the financial default in energy sector firms, which will assist in capital and infrastructure expenditures in the short run.

ABSTRACTIntroductionConsultation audio recordings improve patient decision‐making but are underutilized. Patient‐administered recording apps on mobile devices may increase access, but implementation has not been evaluated.MethodsWe conducted a single‐arm study delivering education, coaching, and reminders for patients to record their appointment using a mobile recording app. Patients had progressive, advanced prostate cancer and an upcoming appointment where the option of docetaxel would be discussed. We used the RE‐AIM framework for evaluation. Reach was the proportion of patients who participated. Effectiveness was change in informed decision‐making pre‐ vs. post‐appointment. We used a questionnaire evaluating patient knowledge about docetaxel (0%–100% correct) and the decisional conflict scale‐informed subscale (0 = feels extremely uninformed to 100 = extremely informed) to compare means using the paired t‐test. Adoption was the proportion of providers agreeing to be recorded. Implementation was coordinator adherence to intervention delivery. We conducted semistructured interviews with patients, caregivers, and providers to assess barriers, facilitators, and suggestions for recording implementation.ResultsOf 102 patients approached, 50 (49%) patients participated. Mean age was 75 years, 38 (76%) were Non‐Hispanic White, and 43 (86%) had telehealth appointments. Knowledge increased from 44.7% to 49.5% (p = 0.019), particularly about palliative care (42% answering correctly to 60%, p = 0.035). Decisional conflict‐informed subscale increased from 48.9 to 70.9 (p < 0.001). Forty‐three patients (85%) made a recording, of whom 33 (77%) reported the recording helped treatment decision‐making. All 17 providers agreed to be recorded. Coordinator adherence was high. Multi‐level barriers, suggestions, and facilitators mostly related to intervention complexity and stakeholder compatibility.ConclusionPatient‐administered audio recordings had a positive effect on decision‐making, particularly for palliative care awareness. For broader implementation, efforts should focus on revising institutional policies; teaching patients or caregivers to use existing recording functions on their devices; leveraging artificial intelligence for transcription and summarization; and integrating recording into telehealth technology and electronic patient portals.Trial Registration: https://clinicaltrials.gov/study/NCT05127850

Authors: Sutton Halley 
Published: November 2024

By the time this article publishes, it is likely that we will know who the American public elected as its next president. No matter the outcome, what seems true is that a politically charged group of college students will continue to engage in civil unrest on campus in connection with a variety of issues. What this means for you as a campus safety leader is that you are likely to continue to see protests on campuses nationwide for years to come over a host of different issues. In the wake of the protests in support of Palestine on campuses over the past year, you need to be ready to address — safely, fairly, and in a way that instills trust in your administration among the student body and campus population — these protests in a timely manner.

ABSTRACTThis study investigates the glucosinolate profiles of various Capparis spp. and Maerua baillonii, from the Capparaceae family, and evaluates the cytotoxic potential of volatile isolates from Capparis spinosa subsp. rupestris. Using UHPLC‐DAD‐MS/MS, GSLs were identified and quantified across different plant tissues. Glucocapparin, predominant glucosinolate in C. spinosa subsp. spinosa, C. spinosa subsp. rupestris, and M. baillonii, were isolated and analyzed by NMR in its desulfo‐form. Notably, glucosinolates were absent in C. richardii and specific tissues of M. baillonii (e.g., leaves and stems), underscoring species and/or tissue‐specific variability within Capparaceae. Less common glucosinolates for Capparaceae plants, such as glucocochlearin, glucohirsutin, and glucoarabin were also detected. Methyl isothiocyanate was found to be the main volatile in all isolates obtained through various isolation methods, comprising ca. 80%–90% of the total volatiles. Methyl isothiocyanate‐rich volatile isolates were tested for cytotoxicity against human breast cancer (MDA‐MB‐231) and bladder cancer (T24) cell lines using the MTT assay, showing significant activity with IC50 values of 3.81 and 5.95 µg/mL, respectively. These findings underscore the anticancer potential of glucocapparin‐bearing plants from the Capparaceae family.

Authors: Wasserman Ellen , Sparks Daniel , Azimi Haleh 
Published: November 2024

ABSTRACTAdult learners, including those who are employed at least part‐time, have children or other family responsibilities, and are older than 25 years can benefit from the flexibility and convenience of online courses. In community colleges, adult learners enroll in online courses at a higher rate than in‐person courses, but their success rates are low, largely due to attrition. Adult learners navigate numerous competing demands on their time and attention, and they seek college experiences that are relevant to their personal and career goals. Instructors need tools to support the unique needs of adult online learners to increase successful outcomes and persistence. This article discusses two classroom interventions that offer models for community colleges to support adult students. The first is a framework to support students in building skills and developing a mindset for self‐directed learning in online coursework. The second is an evidence‐based embedded coaching model for online corequisite courses.

Published: November 2024

AbstractElectrochemical CO2 reduction has attracted significant attention as a potential method to close the carbon cycle. In this study, we investigated the impact of the electrode fabrication and electrolysis conditions on the product selectivity of Ag electrocatalysts using a machine learning (ML) approach. Specifically, we explored the experimental conditions for obtaining the desired H2/CO mixture ratio with high CO efficiency. Notably, unlike previous ML‐based studies, we used experimental results as training data. This ML‐based approach allowed us to quantitatively assess the effect of experimental parameters on these targets with a reduced number of experimental trials (only 56 experiments). An inverse analysis based on the ML model suggested the optimal experimental conditions for achieving the desired characteristics of the electrolysis system, with the proposed conditions experimentally validated. This study constitutes the first demonstration of optimal experimental conditions for electrochemical CO2 reduction with desired characteristics using the experimental results as training data.

Published: November 2024

AbstractIsostructural metal–organic frameworks (MOFs), namely MFU‐4 and MFU‐4‐Br, in which the pore apertures are defined by anionic side ligands (Cl− and Br−, respectively), were synthesized and loaded with noble gases. By selecting the type of side ligand, one can fine‐tune the pore aperture size, allowing for precise regulation of the entry and release of gas guests. In this study, we conducted experiments to examine gas loading and release using krypton and xenon as model gases, and we complemented our findings with computational modeling. Remarkably, the loaded gas guests remained trapped inside the pores even after being exposed to air under ambient conditions for extended periods, in some cases for up to several weeks. Therefore, we focused on determining the energy barrier preventing gas release using both theoretical and experimental methods. The results were compared in relation to the types of hosts and guests, providing valuable insights into the gas trapping process in MOFs, as well as programmed gas release in air under ambient conditions. Furthermore, the crystal structure of MFU‐4‐Br was elucidated using the three‐dimensional electron diffraction (3DED) technique, and the bulk purity of the sample was subsequently verified through Rietveld refinement.

Published: November 2024

AbstractDeveloping efficiency and long‐lived room‐temperature phosphorescence (RTP) materials through straightforward methods is highly desired. In this work, a stepwise stabilization strategy was proposed by the coordination and in‐situ precipitation reactions among organic precursors, inorganic cation and anions, producing room‐temperature phosphorescence materials with high emission efficiency (phosphorescence quantum yield of 45 %). Structural and photophysical characterizations revealed the coordination reaction reduced the energy gaps between singlet and triplet states and stabilized the excited states of the guest molecules. The in‐situ precipitation reaction produced a solid matrix, which provided isolated environments for protecting the excitons from quenching. The applications of RTP materials in information encryption were demonstrated. The presented results provided a new clue for producing RTP materials, and extended their applications in wide fields.
On the derivation of the homogeneous kinetic wave equation
Authors: Collot Charles , Germain Pierre 
Published: November 2024

AbstractThe nonlinear Schrödinger equation in the weakly nonlinear regime with random Gaussian fields as initial data is considered. The problem is set on the torus in any dimension greater than two. A conjecture in statistical physics is that there exists a kinetic time scale depending on the frequency localization of the data and on the strength of the nonlinearity, on which the expectation of the squares of moduli of Fourier modes evolve according to an effective equation: the so‐called kinetic wave equation. When the kinetic time for our setup is 1, we prove this conjecture up to an arbitrarily small polynomial loss. When the kinetic time is larger than 1, we obtain its validity on a more restricted time scale. The key idea of the proof is the use of Feynman interaction diagrams both in the construction of an approximate solution and in the study of its nonlinear stability. We perform a truncated series expansion in the initial data, and obtain bounds in average in various function spaces for its elements. The linearized dynamics then involves a linear Schrödinger equation with a corresponding random potential whose operator norm in Bourgain spaces we are able to estimate on average. This gives a new approach for the analysis of nonlinear wave equations out of equilibrium, and gives hope that refinements of the method could help settle the conjecture.
What is the Exchange Repulsion Energy? Insight by Partitioning into Physically Meaningful Contributions
Authors: Henrichsmeyer Johannes , Thelen Michael , Fink Reinhold F. 
Published: November 2024

AbstractIt is shown that the exchange repulsion energy, Exr, can be rationalized by partitioning the respective energy expression for two systems with Hartree‐Fock orbitals into physically meaningful contributions. A division of Exr into a positive kinetic and a negative potential part is possible, but these contributions correlate only poorly with the actual exchange repulsion energy. A more meaningful partitioning is derived, where all kinetic energy contributions are collected in a term that vanishes for exact Hartree‐Fock orbitals due to their stationarity conditions. The remaining terms can be distinguished into an exchange integral contribution as well as contributions to the repulsion energy with two, three and four orbital indices. The forms, relationships and absolute sizes of these terms suggest an intuitive partitioning of the exchange repulsion energy into Molecular Orbital Pair Contributions to the Exchange repulsion energy (MOPCE). Insight into the analytic form and quantitative size of these contributions is provided by considering the
state of the H2 molecule, the water dimer, as well as an argon atom interacting with Cl2 and N2.
