AbstractPolymer nanocomposites, such as polyethylene terephthalate (PET)‐clay systems, leverage intricate interactions between components to fine‐tune their thermal, mechanical, and rheological properties. In our study, we functionalized montmorillonite clay nanofillers (CloisiteNa+) to fabricate recycled PET‐clay nanocomposites. The nanofillers underwent a three‐step functionalization process, involving the treatment with (3‐Aminopropyl)triethoxysilane (APTES), the grafting of initiating coatings (multifunctional peroxide initiator, [MPI]) onto clay/APTES, and the subsequent fabrication of grafted brushes using poly(butyl methacrylate) (PBMA) or poly(butyl acrylate) (PBA). The functionalization process and the properties of the modified clay were successfully confirmed through Fourier‐transform infrared spectroscopy and thermogravimetric analysis. The fabrication of nanocomposites, incorporating both clay and functionalized clay, influenced the thermal behavior of the composites, whereas the nanofillers had no discernible impact on the flow temperature. The PET and nanocomposites exhibited liquid viscoelastic behavior, with the exception of PET with clay, which displayed shear‐thinning and “rubber‐like” behavior. Rheological curves and x‐ray diffraction (XRD) analysis indicated improved dispersion and compatibility for clay/APTES and clay functionalized with PBA‐grafted brushes within the PET matrix. In some instances, the utilization of functionalized clay resulted in enhanced compatibility and customized properties in PET‐organoclay nanocomposites compared with conventional fillers. These findings bear implications for a broad spectrum of applications involving PET‐organoclay nanocomposites.

AbstractStudies on the property of shape memory in thermoplastic starch (TPS) have shown good results, making such starch a suitable candidate for use in shrink packaging. It is however necessary to evaluate blending it with other bioplastics that would improve its properties while maintaining heat shrinkage. This article thus shows the evaluation of the incorporation of different concentrations of polylactic acid (PLA) and maleic anhydride (MA) as coupling agent and their effect on shrinkage and the changes in structure of the films obtained by blown film extrusion. In most of the blends, the incorporation of PLA and MA was found to favor film shrinkage, obtaining values of up to 55% due to the fact that the interaction between TPS and PLA increased with the incorporation of MA. This was corroborated by the % of MA grafted, thermogravimetric analysis (TGA), rheological and structural tests. This allowed generating a greater molecular orientation of the films, thereby obtaining greater shrinkage. It was determined that the incorporation of PLA and % MA grafted generated good shrinkage results due to the physical and chemical crosslinking achieved in the processing of the blends in the presence of MA, enhancing their application as packaging.

AbstractKissing bugs do not respond to host cues when recently molted and only exhibit robust host‐seeking several days after ecdysis. Behavioral plasticity has peripheral correlates in antennal gene expression changes through the week after ecdysis. The mechanisms regulating these peripheral changes are still unknown, but neuropeptide, G‐protein coupled receptor, nuclear receptor, and takeout genes likely modulate peripheral sensory physiology. We evaluated their expression in antennal transcriptomes along the first week postecdysis of Rhodnius prolixus 5th instar larvae. Besides, we performed clustering and co‐expression analyses to reveal relationships between neuromodulatory (NM) and sensory genes. Significant changes in transcript abundance were detected for 50 NM genes. We identified 73 sensory‐related and NM genes that were assigned to nine clusters. According to their expression patterns, clusters were classified into four groups: two including genes up or downregulated immediately after ecdysis; and two with genes with expression altered at day 2. Several NM genes together with sensory genes belong to the first group, suggesting functional interactions. Co‐expression network analysis revealed a set of genes that seem to connect with sensory system maturation. Significant expression changes in NM components were described in the antennae of R. prolixus after ecdysis, suggesting that a local NM system acts on antennal physiology. These changes may modify the sensitivity of kissing bugs to host cues during this maturation interval.

AbstractGefitinib (GET) is a revolutionary targeted treatment inhibiting the epidermal growth factor receptor's tyrosine kinase action by competitively inhibiting the ATP binding site. In preclinical trials, several lung cancer cell lines and xenografts have demonstrated potential activity with GET. Response rates neared 25% in preclinical trials for non‐small cell lung cancer. Here, we describe the one‐pot synthesis of GET@ZIF‐8 nanocomposites (NCs) in pure water, encapsulating zeolitic imidazolate framework 8 (ZIF‐8). This method developed NCs with consistent morphology and a loading efficiency of 9%, resulting in a loading capacity of 20 wt%. Cell proliferation assay assessed the anticancer effect of GET@ZIF‐8 NCs on A549 and H1299 cells. The different biochemical staining (Calcein‐AM and PI and 4′,6‐Diamidino‐2‐phenylindole nuclear staining) assays assessed the cell death and morphological examination. Additionally, the mode of apoptosis was evaluated by mitochondrial membrane potential (∆ψm) and reactive oxygen species. Therefore, the study concludes that GET@ZIF‐8 NCs are pledged to treat lung cancer cells.

Published: April 2024

AbstractResearch has highlighted the advantages of specific practices for enhancing student learning. However, the adoption of these practices varies among teachers. This disparity raises fundamental questions: Why do certain teachers use these practices while others do not? Does the use of these practices depend on the career stage of the teachers? This paper analyses the practices adopted by teachers at different career stages. We used a mixed‐methods approach, combining a questionnaire (n = 300) and three focus group discussions (n = 13). The results revealed significant variability in the use of pedagogical practices among novice, experienced and senior teachers. Experienced and senior teachers demonstrate a deeper understanding of adapting teaching methods to student needs, establishing clear objectives and providing feedback. However, certain practices, such as metacognition, remain underused at all career stages. The study highlights the need for professional development concerning these practices, while emphasising the challenge of their implementation.
Corporate governance structure and climate‐related financial disclosure: Conventional banks versus Islamic banks

Published: April 2024

AbstractThis paper examines whether the different corporate governance structures of conventional banks (CBs) and Islamic banks (IBs) have varying effects on their respective climate‐related disclosure (CRD). Employing a unique dataset of CBs and IBs' CRD and corporate governance structures for the period of 2016–2019, we found that their respective corporate governance structures did indeed affect their CRD in different ways. Our findings suggest that CBs disclose more climate‐related information than IBs because IBs focus on Sharia compliance which does not emphasise the protection of the environment, while CBs may be more responsive to shareholders' and stakeholders' demands on climate and environment. These effects were stronger with the quality of governance, that is, CBs disclose more climate‐related information with the governance quality, while IBs disclose even less when their governance quality increases. The findings of this study have important implications for climate change, especially the Paris Accord and The 26th Meeting of the Conference of Parties (COP26). There are also policy implications for sustainable financial markets and the financial services sector.

AbstractBackgroundOvarian cancer is the most lethal of all gynecological cancers. Cancer Antigen 125 (CA125) is the best‐performing ovarian cancer biomarker which however is still not effective as a screening test in the general population. Recent literature reports additional biomarkers with the potential to improve on CA125 for early detection when using longitudinal multimarker models.MethodsOur data comprised 180 controls and 44 cases with serum samples sourced from the multimodal arm of UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS). Our models were based on Bayesian change‐point detection and recurrent neural networks.ResultsWe obtained a significantly higher performance for CA125–HE4 model using both methodologies (AUC 0.971, sensitivity 96.7% and AUC 0.987, sensitivity 96.7%) with respect to CA125 (AUC 0.949, sensitivity 90.8% and AUC 0.953, sensitivity 92.1%) for Bayesian change‐point model (BCP) and recurrent neural networks (RNN) approaches, respectively. One year before diagnosis, the CA125–HE4 model also ranked as the best, whereas at 2 years before diagnosis no multimarker model outperformed CA125.ConclusionsOur study identified and tested different combination of biomarkers using longitudinal multivariable models that outperformed CA125 alone. We showed the potential of multivariable models and candidate biomarkers to increase the detection rate of ovarian cancer.

Published: April 2024

Key Clinical MessageHematopoietic neoplasms can cause adrenal infarction. In cases of thrombosis occurring at uncommon sites, it is necessary to consider evaluating for the JAK2V617F mutation, even in the absence of notable abnormalities in blood counts.AbstractAdrenal infarction, a rare ailment, has been sporadically linked to hematopoietic neoplasms. A 46‐year‐old male encountered left adrenal infarction, which coincided with a progressive rise in platelet counts. Subsequent diagnosis revealed myelodysplastic/myeloproliferative neoplasm‐unclassifiable, featuring a JAK2V617F mutation. Simultaneously, the patient manifested multiple arteriovenous thromboses, necessitating treatment with edoxaban, aspirin, and hydroxyurea. Following thrombosis resolution, he was transferred to a transplantation center. This report delves into the thrombogenicity linked to the JAK2V617F mutation, while also examining documented instances of adrenal infarction in myeloid neoplasms. We should consider evaluating for JAK2V617F mutation even in cases of thrombosis at unusual sites, including adrenal infarction, even if there are no considerable abnormalities in blood counts.

AbstractYlide‐functionalized phosphines (YPhos) have been shown to yield highly active gold catalysts owing to their high donor capacity. To examine the impact of ylide functionalization on a given ligand structure, a series of ferrocenyl diphosphines functionalized with no, one or two ylide moieties and their corresponding bimetallic gold complexes were prepared. The complexes feature an anti‐conformation of the two phosphine moieties, guaranteeing the presence of two independent metal centers. Comparative studies of the complexes in the hydroamination and hydrohydrazination of alkynes revealed a significant increase in catalytic activity for each newly introduced ylide group. The di‐YPhos ligands were revealed to be the most active precatalysts, functioning effectively even at 0.1 or 0.2 mol % catalyst loading. This catalytic efficiency was demonstrated for a series of alkynes, amines and hydrazines.

Published: April 2024

AbstractKinetic inertness of Mn(II)‐based MRI contrast agents can be improved by increasing the rigidity of the polydentate ligand that tightly coordinate the metal ion. Taking inspiration from the remarkable increase in kinetic inertness of [Mn(CDTA)]2− compared to [Mn(EDTA)]2− due to the cyclohexyl backbone rigidity, we devised that bicyclic ligands would further improve the kinetic inertness of the Mn(II) complexes. The length of the alkyl bridge on the cyclohexane ring was varied from methylene (BCH‐DTA), ethylene (BCO‐DTA) to propylene (BCN‐DTA) to evaluate the influence of the different trans‐diaminotetraacetate ligands on relaxometric, thermodynamic and kinetic properties of the Mn(II) complexes. 1H and 17O NMR relaxometric studies showed a slight increase in relaxivity and a faster water exchange rate in these Mn(II)‐complexes with respect to [Mn(CDTA)]2−. Solution studies revealed that the conditional stability (pMn) and dissociation half‐life (t1/2) at pH 7.4 follow the order [Mn(BCH‐DTA)]2−<[Mn(BCO‐DTA)]2−<[Mn(BCN‐DTA)]2− highlighting the effect of the bridge length on the overall stability of the Mn(II) complexes. Remarkably, [Mn(BCN‐DTA)]2− shows an improved pMn value and a 7‐times higher kinetic inertness than [Mn(CDTA)]2−. NMR studies on the Zn(II) analogues confirm the rigidity of the bicyclic complexes with an isomerization process at >313 K for the smaller bridged complex [Zn(BCH‐DTA)]2−.
Chemoselective Post‐Synthesis Modification of Pyridyl‐Substituted, Aromatic Phosphorus Heterocycles: Cationic Ligands for Coordination Chemistry
Authors: Dettling Lea , Papke Martin , Ernst Moritz J. , Weber Manuela , Müller Christian 
Published: April 2024

AbstractTriazaphospholes are potential polydentate ligands due to the presence of both phosphorus and nitrogen donor atoms within the aromatic 5‐membered heterocycle. The incorporation of an additional pyridyl‐substituent opens up the possibility of a post‐synthesis modification via chemoselective and also stepwise alkylation exclusively of the nitrogen atoms. This can be controlled by the choice and by the stoichiometry of the electrophile and allows the targeted synthesis of a variety of novel mono‐ and dicationic ligands. Reaction with Cu(I)‐halides causes the formation of cuprates of the type [CuXn](n−1)−, which enables coordination of the π‐acidic phosphorus donor to the negatively charged metal core, which is favored over the coordination by a strongly σ‐donating nitrogen atom. The use of cationic triazaphosphole derivatives can be used as a strategy to enforce the coordination of the ligand to an electron rich metal solely via the phosphorus atom. However, there is a subtle balance between the formation of either coordination polymers or dimeric structures, as the substitution pattern on the heterocycle and the nature of the halide have a large influence on the coordination motifs formed.

AbstractPhotoionization and dissociative photoionization of acetaldehyde (CH3CHO) in the 10.0–13.7 eV energy range are studied by using synchrotron radiation double imaging photoelectron photoion coincidence spectroscopy (i2PEPICO). The X2A′ and A2A“ electronic states of CH3CHO+ as well as the Franck‐Condon gap region between these two states have been populated with several vibrational sequences and assigned in the high‐resolution slow photoelectron spectrum (SPES). The adiabatic ionization energies (AIEs) of the X2A′ and A2A” states are measured at 10.228±0.006 and 12.52±0.05 eV, respectively. The present results show that the X2A′ state is a stable state while the A2A“ state is fully dissociative to produce CH3CO+, CHO+ and CH4+ fragment ions. The 0 K appearance energies (AE0K) of CH3CO+ and CHO+ fragment ions are determined through the modeling of the breakdown diagram, i. e., AE0K(CH3CO+)=10.89±0.01 eV (including a reverse barrier of ~0.19 eV) and AE0K(CHO+)=11.54±0.05 eV. In addition, the dissociation mechanisms of CH3CHO+ including statistical dissociation, direct bond breaking and isomerization are discussed with the support of the calculated dissociation limits and transition state energies.

Published: April 2024

AbstractObjectiveTo investigate the effect of common beverages on four currently used provisional restoration materials: Protemp®4, Integrity®, polymethyl methacrylate (PMMA) block, and acrylic resin. Flowable resin composite is included as a control group.Materials and MethodsEach material was formed into disks of 10‐mm diameter and 4‐mm thickness (N = 40) by loading the material into acrylic molds. The exposed surface in the mold was covered using a glass slide to prevent an oxygen inhibition layer, and polymerization then proceeded. The solidified disks were placed in distilled water for 24 h. These samples (n = 8) were then immersed for 14 days in one of four different beverages: water, orange juice, cola, and coffee. Changes in color dimension, hardness, and roughness were observed and then analyzed using two‐way repeated analysis of variance.ResultsThe provisional materials had more obvious changes in all three color dimensions than the flowable resin composite. Integrity showed the biggest changes, followed by acrylic resin and PMMA block, whereas Protemp had the smallest changes. The hardness of all the materials significantly decreased after immersion in any of the beverages for 14 days. There were no changes in surface roughness when the materials were immersed in distilled water. The surface roughness of the PMMA block significantly decreased in orange juice whereas that of Integrity and acrylic resin significantly increased in cola.ConclusionDifferent kinds of provisional materials had different degrees of staining due to their composition. Moisture had a significant influence on the hardness of materials, and the acidity of cola significantly roughened the surface of the provisional materials.

Published: April 2024

AbstractThe current study examines the intermediary procedures (mediators and moderators) which underlie the corporate social responsibility (CSR)‐employee burnout link. Burnout is a multifaceted psychological construct that has been widely explored in the academic literature and is related to important outcomes for individuals and organizations. Despite its significance, few studies have investigated the impact of CSR on burnout. The present research proposes that CSR diminishes employee burnout through the sequential mediation of psychological safety and job stress. Additionally, this paper proposes that work overload negatively moderates the influence of CSR on employee psychological safety. Survey data obtained from 413 South Korean workers over three‐waves were utilized, and structural equation modeling was used to test a moderated mediation model with related hypotheses. The findings demonstrated that CSR diminishes employee burnout via sequential mediation of psychological safety and job stress. Furthermore, work overload has a negative moderating influence on the association between CSR and psychological safety. The practical and theoretical implications of this research are described.
