Published: December 2024

AbstractMechanoresponsive photonic crystals (MPCs) exhibit tunable optical properties and hold great promise for a wide range of applications. However, fabricating them in bulk form remains a significant challenge. In this study, a novel approach is presented for producing bulk MPCs with enhanced optical properties. By incorporating shear‐ordering into the 3D molding process, this study successfully fabricates bulk MPCs that display bright, saturated structural colors with 80% reflectance. The bulk MPCs are constructed layer‐by‐layer via successive shear‐printing using colloidal particles embedded in photocurable resins. Each layer is subjected to oscillatory shear facilitated by a modified 3D printing setup. This process creates a highly ordered face‐centered cubic lattice structure throughout the bulk material. The final product exhibits distinct colors on its various faces, depending on the lattice planes exposed at different orientations. The material is highly strain‐resilient, with pronounced color shifting in response to applied stress. A detailed experimental study of the shear‐ordering mechanism and the resulting structures is provided. This method offers an efficient way to fabricate bulk MPCs with optical performance comparable to the best thin films and can be extended to more complex shapes.

ABSTRACTA new novel NO pincer type bezo[d]thiazole ligand, 2‐(5,6‐dichlorobenzo[d]thiazol‐2‐yl)phenol (HDCBTP) is synthesized through reacting 2‐amino‐4,5‐dichlorobenzenethiol and 2‐hydroxybenzoic acid in 1:1 ratio. Nano‐sized bivalent Pt (II) complex is created and subsequently characterized using various physical methods. The complex structural geometry is validated by employing the density functional theory (DFT) approach, utilizing DMOL3 determinations. Based on the elemental analysis results, the complexes are inferred to follow the overall formula [Pt (DCBTP)2]. Quantum chemical calculations, along with electronic spectra findings, indicate that Pt (II) complex exhibits a square planar configuration. The XRD, EDX, TEM, and AFM analyses of the studied complex unveil distinct and strong diffraction peaks, indicating its crystalline nature and providing evidence of its nano‐sized particle sizes. Viscosity measurements and absorption titration techniques were used to study the interaction between Pt (II) complex and CT‐DNA. The results showed that the complexes were bound to CT‐DNA via a typical intercalation binding mode. The in vitro antimicrobial efficacy of HDCBTP and its Pt (II) complex was inspected against various bacterial and fungal pathogens. The results highlight these compounds as a highly effective fungicides and bactericides. In vitro cytotoxic effects of the formulated complex were explored utilizing PC3 prostate cancer cell lines. According to IC50 and selective index (SI) measurements, it was shown that the complex exhibited higher potency against HePG2 cell lines. Moreover, Pt (II) complex exhibited the capability for triggering DNA damage in HePG2 cells, resulting in dose‐dependent cell apoptosis. Subsequent investigations revealed that complex triggered cell cycle arrest during the S and G2 phases.

Published: December 2024

ABSTRACTAn intrinsic flame‐retardant P(AN‐co‐IPADE) copolymer was synthesized via aqueous deposited polymerization, enhancing the thermal stability and flame retardancy of polyacrylonitrile (PAN). Limiting oxygen index (LOI), cone calorimetry, and thermogravimetric analysis (TGA) were used to reveal significant improvements in flame retardancy and thermal stability due to the integration of isopropenyl‐phosphonic acid dimethyl ester (IPADE). Notably, the copolymer exhibited an LOI value of 31.0% with an IPADE content of just 20.4 wt%, and a remarkable 80% reduction in both the peak heat release rate and total heat release, underscoring its exceptional flame‐retardant properties. The emission of hazardous smoke components, including hydrogen cyanide (HCN), nitrogen oxides (NOx), and carbon monoxide (CO), was effectively mitigated. The flame‐retardant mechanism was explored, and the bond dissociation enthalpy (BDE) of the primary groups within the polymer chains was calculated to understand the pyrolysis process. Complementary analyses using X‐ray photoelectron spectroscopy (XPS), Raman spectroscopy, and pyrolysis‐gas chromatography–mass spectrometry (Py/GC–MS) suggest that IPADE contributes to both the gaseous and condensed phases, forming a comprehensive flame‐retardant mechanism.

Published: December 2024

AbstractPoly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), a conductive polymer, have attracted attention as promising materials for future electronic applications, owing to its tunable doping level for high electrical conductivity (σ) through simple post‐treatments. A novel post‐treatment method for conventionally doped PEDOT:PSS thin‐films (immersed in methanol) is presented to further enhance σ via doping with the superacid, trifluoromethanesulfonic acid (TFSA). The origin of the improved σ in PEDOT:PSS thin‐films treated with this dual approach is investigated. The study reveals that the superacid vapor treatment uniquely enhances the lamellar stacking of PEDOT chains and induces vertical phase separation between PEDOT and PSS, leading to improved carrier mobility by a factor of three. This behavior differs from conventional post‐treatments, making the combined methanol immersion and TFSA vapor treatment an effective strategy for achieving a high σ of ≈2053 S cm−1, making these films ideal candidates for various polymer‐based electronics. Furthermore, the findings demonstrate that the thermoelectric power factor of PEDOT:PSS subjected to secondary doping with superacid vapor exhibits a threefold enhancement (104.2 µW m−1 K−2) compared to samples treated solely with methanol (29.7 µW m−1 K−2). This post‐treatment method and the resulting insights will advance the understanding of doping mechanisms and charge transport in conductive polymers.

ObjectiveSystemic sclerosis (SSc) is a rare but severe autoimmune disease characterized by immune dysregulation, fibrosis, and vasculopathy. Although previous studies have highlighted the presence of functional autoantibodies targeting the angiotensin II receptor type 1 (AT1) and endothelin‐1 type A receptor (ETAR), leading to autoantibody‐mediated receptor stimulation and subsequent activation of endothelial cells (ECs), a comprehensive understanding of the direct interaction between these autoantibodies and their receptors is currently lacking. Moreover, existing data confirming the presence of these autoantibodies in SSc often rely on similar methodologies and assays. Our aim was to replicate previous findings and to investigate the functional effects of IgG derived from patients with SSc (SSc IgG) on AT1 and ETAR signaling, the downstream EC response, and the presence of AT1‐binding autoantibodies in circulation.MethodsQuantitative polymerase chain reaction and cytokine enzyme‐linked immunosorbent assay, alongside a real‐time cell analyzer, were used to assess receptor‐specific functional characteristics of purified SSc IgG (n = 18). Additionally, a novel protein capture assay using solubilized epitope‐tagged AT1 was developed to detect AT1‐binding autoantibodies in plasma samples from patients with SSc (n = 28) and healthy donors (n = 14).ResultsNo evidence for EC activation in an AT1‐ or ETAR‐dependent manner was revealed. Furthermore, stimulation with SSc IgG did not induce receptor activation or alter G protein‐coupled receptor signaling on agonist stimulation in a model with receptor overexpression. Lastly, no AT1‐binding autoantibodies were detected in plasma samples from patients with SSc when using epitope‐tagged solubilized AT1.ConclusionOverall, our study did not provide evidence to support the presence of AT1‐ or ETAR‐activating autoantibodies in purified SSc IgG or AT1‐binding autoantibodies in the circulation of patients with SSc.
Thermosensory Roles of G Protein‐Coupled Receptors and Other Cellular Factors in Animals
Authors: Ohnishi Kohei , Sokabe Takaaki 
Published: December 2024

ABSTRACTIn this review, we introduce the concept of “dual thermosensing mechanisms,” highlighting the functional collaboration between G protein‐coupled receptors (GPCRs) and transient receptor potential (TRP) channels that enable sophisticated cellular thermal responsiveness. GPCRs have been implicated in thermosensory processes, with recent findings identifying several candidates across species, including mammals, fruit flies, and nematodes. In many cases, these GPCRs work in conjunction with another class of thermosensors, TRP channels, offering insights into the complex mechanisms underlying thermosensory signaling. We examine how GPCRs function as thermosensors and how their signaling regulates cellular thermosensation, illustrating the complexity of thermosensory systems. Understanding these dual thermosensory mechanisms would advance our comprehension of cellular thermosensation and its regulatory pathways.

Published: December 2024

ABSTRACTDespite the recent growth in research on analysing the influence of stakeholders' green pressure on firm performance, our understanding of the subject seems limited, especially regarding the positive and negative influence of many internal and external stakeholders and the mediating roles of environmental orientation and commitment. Analysing primary data from 317 Japanese SMEs, we found that environmental orientation has negative while environmental commitment positively influences firm performance. Besides, the findings also show that green pressure from regulators, competitors, non‐governmental organisations (NGOs) and employees significantly influences the market and financial performance, followed by a discussion of relevant theoretical and practical implications.
The Need to Increase Help‐Seeking for Eating Disorders in General and Binge‐Eating Disorder Specifically: Commentary on Ali et al.'s (2024) Meta‐Analysis
Authors: Lydecker Janet A. 
Published: December 2024

ABSTRACTAli et al.'s (2024) systematic review and meta‐analysis updated a previous meta‐analysis on the gap between the need for eating disorder treatment and rates of seeking and receiving eating disorder treatment. They found that less than one‐third of individuals with eating disorders sought help for their eating disorder, which was an improvement of only 8% over more than a decade. This updated analysis makes it apparent that we need to dedicate research and resources to meeting this treatment need. Building on this work, this commentary reviews changes in help‐seeking behaviors, particularly online help‐seeking. The commentary also discusses binge‐eating disorder (BED) help‐seeking because the addition of BED as a diagnosis occurred in the time between the original and updated meta‐analysis. Barriers to seeking eating disorder treatment, including identifying behaviors as indicative of an eating disorder and problematic, appear pronounced among individuals with BED. The commentary concludes by highlighting that it is essential to direct research and policy efforts along multiple pathways to close the gap between those who need and those who seek eating disorder treatment.

Authors: Attia Mohammed El Hadi , Abdelgaied Mohamed , Harby K. 
Published: December 2024

AbstractThis article presents an effective, economical, and health‐safe experimental work to improve the solar distiller's performance using cement conical fins. To demonstrate the effectiveness of conical cement fins, two distillers were designed and built, in the first distiller; a basin was made from cement (SSSD‐CB). In the second distiller, the uniformly distributed cement conical fins are installed in the basin (SSSD‐CB&CCF). The results presented that the cumulative water produced from SSSD‐CB and SSSD‐CB&CCF reached 3460 and 4750 mL/m2 day, respectively. These results indicated that the conical cement fins represent a good design that improves the yield by 37.28%. Also, the average improvement in the exergy and energy efficiencies for SSSD‐CB&CCF reached 71.24% and 37.3%. The economic analysis showed that using conical cement fins reduced distilled costs by 25.38%.
Prediction of Inflorescence Emergence in ‘Yu Her Pau’ Litchi Under Climate Change Using an Optimised Model
Authors: Chang JenYu , Tang Lisa , Chen Chu‐Chung , Zhang Yi‐Ting , Chen Chi‐Ling 
Published: December 2024

ABSTRACTFor litchi (Litchi chinensis), successful floral induction requires adequate cool temperatures in winter, perceived by mature leaves like many other subtropical fruit species. As a result, rising ambient temperatures due to global climate change has posed a threat to litchi flowering and fruit production. The goal of this research was to assess the potential impacts of climate change on flowering in ‘Yu Her Pau’ litchi on Taiwan. To better characterise the relationship between temperatures and inflorescence emergence (IE), we built a model by applying the beta‐distribution function method with 12 phenological datasets (two orchard blocks for 6 years) recorded from field‐grown ‘Yu Her Pau’ litchi trees. For this predictive model, the minimum, maximum, and optimal temperatures that resulted in successful floral induction were estimated to be 0.0°C, 21.9°C, and 19.8°C, respectively; under these criteria, at least 60.37 units of cumulative cool temperatures are necessary for IE based on the historical data. Subsequently, the IE model was used to evaluate the likelihood of successful flowering in ‘Yu Her Pau’ litchi at four major producing areas on Taiwan during five decades from 2026 to 2075, respectively, under three separate climate change (emission) scenarios based on three General Circulation Models (GCMs) in. Our results, based on any of the GCMs, suggested that ‘Yu Her Pau’ litchi grown on Southern Taiwan could face poor flowering due to insufficient cool winter temperatures in the coming decade even in the emission scenario with very stringent mitigation effort, which can lead to serious crop loss in the near future.
Volatile Profile of Bee Pollens: Optimization of Sampling Conditions for Aroma Analysis, Identification of Potential Floral Markers, and Establishment of the Flavor Wheel
Authors: Csóka Mariann , Végh Rita , Sipos László 
Published: December 2024

ABSTRACTThe volatile profile of bee pollen samples from Central and Eastern Europe was investigated by headspace solid phase microextraction (HS‐SPME) combined with gas chromatography–mass spectrometry‐olfactometry (GC–MS‐O). Sampling conditions were optimized for the extraction of volatiles. Pollen odorants were extracted with six different fiber coatings, five various extraction times, three diverse extraction temperatures and three differing desorption times. The most effective combination was the application of divinylbenzene/carboxen/polydimethylsiloxane (DVB/CAR/PDMS) fiber coating used at 60°C for 30 min for extraction and 1 min for desorption. The optimized method was applied to investigate the volatile profile of 14 pollen samples (three rapeseed, musk thistle, rock‐rose, traveler's joy, dropwort, honey locust, sunflower, red poppy, phacelia, sweet cherry, wild blackberry, and dandelion). The volatile profiles of bee pollens were different and were crucially depended on botanical origin. The aroma activity of the samples was generated by 31.0%–48.3% of total volatiles. The number of the identified odorants were between 75 and 101 in the pollen samples by GC–MS, of which 26–42 were aroma‐active. The volatile organic compounds (VOCs) were classified into 13 different chemical classes. In most pollen, fatty acids were the predominant volatiles (14.87%–50.58%), while in some samples esters were the most abundant odorants (4.09%–45.46%). Panelists confirmed the presence of six main sensory characteristics described as “green/sour”, “fruity”, “spicy/herbal”, “earthy/mushroom”, “sweet/baked/caramel/honey”, and “floral” compounds. These results establish the flavor wheel suitable for the comprehensive sensory description of pollen pellets from individual plant species. All samples contained characteristic odorants that may help in their botanical identification.
The Challenges of Gender Diversity in Boards of Directors: An Australian Study with Global Implications
Authors: Young Suzanne , Farquharson Karen , De Silva Daswin , Mather Paul 
Published: December 2024

AbstractDespite gender diversity being driven by institutional bodies, companies have been relatively slow to diversify. In this study, it is investigated that how Australian boards select new directors, and how those selection processes affect their recruitment of women. In‐depth interviews are conducted of those with first‐hand experience of board appointments, followed by the thematic analysis and the application of natural language processing techniques to identify emotions and sentiment associated with these themes. The findings indicate that boards are adopting a social rather than rational approach to board selection. They are using networks, recruitment agencies, skills matrices and pools which on the surface appear to broaden the diversity of board members. But if they are not actively seeking gender diversity these methods can still limit diversity. For women, the lack of progress and barriers of access are resulting in high intensity of negative emotions. A key contribution of the research is the intersection of social approaches to board appointment and social identity theory with the dynamics of gender. Boards need to prioritize diversity for it to be achieved. There is a need for more active methods of recruitment and expansion of the networks and pools where directors are traditionally sought. Institutions can drive change through increasing targets and requiring enhanced reporting.

Published: December 2024

ABSTRACTThe relative ease of generation and proliferation of omics datasets has moved considerably faster than the effective dissemination of these data to the scientific community. Despite advancements in making raw data publicly available, many researchers struggle with data analysis and integration. We propose sharing analyzed data through user‐friendly platforms to enhance accessibility. Here, we present a free, online tool, for sharing basic omics data in a searchable and user‐friendly format. Importantly, it requires no coding or prior computational knowledge to build—only a data spreadsheet. Overall, this tool facilitates the exploration of transcriptomic, proteomic, and metabolomics data, which is crucial for understanding glial diversity and function. This initiative underscores the importance of accessible molecular data in advancing neuroscience research.
