Published: November 2023

AbstractPolyurethane (PU) materials with high strength, toughness, anti‐wear properties, and high heat resistance are in high demand for dynamic sealing applications. In this study, a series of high‐performance crosslinking polyurethanes (CPUs) were prepared by pre‐polymerization of polycarbonate diol (PCDL) with toluene‐2,4‐diisocyanate (TDI), followed by crosslinking with trimethylolpropane (TMP). The molar ratio (R) of PCDL/ TDI and the degree of cross‐linking were found to significantly affect the microphase separation. The results indicate that as the R‐value increases, the transition temperature of CPUs increases from 6.0°C to 82.4°C, and the tensile strength increases from 21.1 ± 2.5 MPa to 46.0 ± 3.6 MPa. Moreover, the CPUs exhibit excellent heat resistance (with a heat resistance index of ~150°C) and hydrolysis resistance, attributed to the high crystallinity of PCDL and the synergistic effect of chemical crosslinking. Additionally, the CPUs demonstrate low friction coefficient (COF = 0.01–0.062), exceptional anti‐wear properties (Akron wear, 0.11–0.07 cm3/1.61 km), and outstanding fatigue resistance. These desirable characteristics make CPUs suitable for use as dynamic sealing or lubricating materials in harsh conditions, thereby extending the service life of seals and preventing leakage and other related issues.

Published: November 2023

AbstractIn this work, the synthesis and characterization of highly aromatic bisoxazoline (BOX) monomers containing diphenyl ether, furan, and thiophene backbones are presented. Preliminary investigations of the cure and reaction kinetics are performed to understand the impact of these moieties on polymerization and their glass transition temperatures. To do this, two catalysts are used, methyl triflate (MT) and dodecyl benzene sulfonic acid (DBS) to explore their role in controlling the cationic ring‐opening polymerization (CROP) mechanism. Polymerization was monitored using non‐isothermal differential scanning calorimetry and characterized according to the Kissinger and Ozawa models. Kinetic modeling using the Malek and Sestak‐Berggren methods showed excellent agreement with experimental values and was used to determine reaction rate constants. The polymerization of BOX monomers in the presence of both MT and DBS is shown to be highly latent, being stable until the melting point is reached, after which reaction occurs rapidly.
The conspiracy narrative “The Big Lie”—Psychoanalytical considerations on the development of susceptibility to an “alternative reality”
Authors: Zienert‐Eilts Karin Johanna 
Published: November 2023

AbstractUsing the narrative “The Big Lie,” which is placed in the socio‐political context, and based on data gathered from social media, clinical material, interviews and documentaries, the author examines from a psychoanalytic perspective the effective power and dynamics of conspiracy narratives that create an “alternative reality” with “conviction capsules,” using lies and distortions of reality consciously employed as means of agitation on the breeding ground of unconscious relational and regression processes. To sketch the emergence and development of this willingness, the author combines the explanations of Wilfred Bion, Susan Isaacs and Herbert Rosenfeld and develops the hypothesis, including the concept of “perverted containing,” that due to unsuccessful containing processes in the earliest relationship experiences, defensively inflexible, sealed “conviction capsules” develop, permeated by fears of confusion and annihilation, by hatred as well as phantasies of powerlessness and superiority. Underlying these, experienced as existentially threatening, are panic about change and excessive identification with a hard, alleged omnipotent object, linked to an unconscious longing for symbiosis with a “savior”—a conglomerate that breeds susceptibility to conspiracy narratives and totalitarian, destructive populist leaders. As one example, the destructive‐symbiotic relationship dynamic between Donald Trump and his supporters is outlined with the escalation of violence.
Varieties of diffusion in academic publishing: How status and legitimacy influence growth trajectories of new innovations
Authors: Siler Kyle , Larivière Vincent 
Published: November 2023

AbstractOpen Access (OA) publishing has progressed from an initial fringe idea to a still‐growing, major component of modern academic communication. The proliferation of OA publishing presents a context to examine how new innovations and institutions develop. Based on analyses of 1,296,304 articles published in 83 OA journals, we analyze changes in the institutional status, gender, age, citedness, and geographical locations of authors over time. Generally, OA journals tended towards core‐to‐periphery diffusion patterns. Specifically, journal authors tended to decrease in high‐status institutional affiliations, male and highly cited authors over time. Despite these general tendencies, there was substantial variation in the diffusion patterns of OA journals. Some journals exhibited no significant demographic changes, and a few exhibited periphery‐to‐core diffusion patterns. We find that although both highly and less‐legitimate journals generally exhibit core‐to‐periphery diffusion patterns, there are still demographic differences between such journals. Institutional and cultural legitimacy—or lack thereof—affects the social and intellectual diffusion of new OA journals.

AbstractThe interactions between drugs and proteins play a pivotal role in determining the pharmacological effects and disposition of drugs within the human body. This study focuses on exploring the interaction between nitrendipine and lysozyme/human serum albumin. Spectroscopic analysis indicated a compound static quenching, indicative of the formation of stable complexes between the drug and proteins. The addition of vitamin C or naringin resulted in a decrease of the binding constant between nitrendipine and lysozyme/human serum albumin. The presence of these compounds may disrupt the interactions between the drug and proteins, potentially leading to an increased concentration of free nitrendipine in the bloodstream. Nitrendipine binds more easily to human serum albumin at 310 K, and human serum albumin has an average binding site ratio with nitrendipine approximately 0.1 higher than that with lysozyme. Vitamin C has a greater impact on the binding constant of nitrendipine to human serum albumin and lysozyme. Compared to the binary system of proteins with the drug, the ternary system with the addition of vitamin C at 310 K reduces the binding constants of lysozyme and human serum albumin by 85%. In conclusion, this study explores the significance of considering drug–protein interactions in understanding drug behavior and potential drug–food interactions.

Published: November 2023

AbstractThe fabrication of structured zeolite adsorbents through photopolymerization‐based 3D printing which offers a solution to the limitations of conventional shaping techniques has been demonstrated but many parameters still need to be optimized. In this study, we studied the influence of zeolite compensation cations on the photopolymerization and the composite's properties. Modified zeolites (LTA 4 A and FAU 13X exchanged with K+, Li+, Sr2+, Ca2+ or Mg2+) were incorporated in PEGDA with BDMK as photoinitiator, and the formulation was cured under mild conditions (LED@405 nm, room temperature, under air). Our results indicate that the nature of zeolite compensation cations affects the colorimetric properties of polymer/zeolite composites: a better translucency parameter results in higher depth of cure. After calcination at 650 °C and complete removal of PEGDA, pure zeolitic monoliths were tested for adsorption of gas molecules of interest (carbon dioxide, dichlorobenzene and water). Structured 4 A and 13X monoliths obtained by 3D printing exhibit comparable adsorption capacity to commercial beads prepared from the same zeolites. This study enhances our understanding of the photopolymerization process involved in the production of polymer/zeolite composites. These composites are used in the fabrication of zeolitic objects through 3D printing, offering potential solutions to various environmental and dental challenges.
Scalability analysis of a two level domain decomposition approach in space and time solving data assimilation models
Authors: Cacciapuoti Rosalba , D'Amore Luisa 
Published: November 2023

SummaryWe are concerned with the mapping on high performance hybrid architectures of a parallel software implementing a two level overlapping domain decomposition, that is, along space and time directions, of the four dimensional variational data assimilation model. The reference architecture belongs to the SCoPE (Sistema Cooperativo Per Elaborazioni scientifiche multidisciplinari) data center, located at University of Naples Federico II. We consider the initial boundary problem of the shallow water equation and analyse both strong and weak scaling. Keeping the efficiency always greater than and about in most cases, we experimentally find that the isoefficiency function grows a little more than linearly with respect to the number of processes. Results, obtained by using the parallel computing toolbox of MATLABR2013a, are in agreement with the algorithm's performance prevision based on the scale up factor, confirming the appropriate mapping of the algorithm on the hybrid architecture.

Published: November 2023

AbstractGraphite‐based dual‐ion batteries are with potential higher energy density, making them a unique candidate in energy storage systems. However, anion insertion into graphite in aqueous environment remains a significant challenge. Herein, we report that the reversible insertion of Al‐Cl superhalide into expanded graphite (EG) delivers an ultrahigh specific capacity of ~171 mAh g−1 from an aqueous deep eutectic solvent (DES) gel electrolyte of 50 m ChCl+5 m AlCl3. High‐resolution transmission electron microscopy (HRTEM), Raman spectra and X‐ray diffraction (XRD) show that the EG generates turbostratic structure during Al‐Cl superhalide (de)insertion instead of presenting typical graphite intercalation compounds (GIC), thus attributing to the high capacity during Al‐Cl superhalide insertion.
Radiation in a plasma and applications to cosmic microwave background
Authors: Trigger Sergey 
Published: November 2023

AbstractIn a recent paper [Phys. Rev. E 100, 023202 (2019)], Munirov and Fish proposed application of the well‐known approach for the calculation of the fluctuation field radiation spectrum in a transparent fully ionized plasma to the problem of cosmic microwave background. They used the result for spectral energy distribution of the equilibrium radiation, assuming that the spectrum of free photons is changed to the non‐damping spectrum of transverse waves in non‐relativistic plasma. The similar approach has been considered earlier by several authors for non‐relativistic and relativistic plasmas. The results of Munirov and Fish are in fact in perfect agreement with the most of the previously existing expressions. However, we argue that this approach based on such simple approximation is not enough justified and the more elaborated consideration, taking into account not only temporal but also spatial dispersion of dielectric permittivity is necessary for a consistent description of radiation in plasmas. Moreover, interaction between free photons and charged particles in the framework of quantum electrodynamics leads to the result different in comparison with the standard consideration even for the transparent plasma medium.

AbstractSpecies interactions can influence species distributions, but mechanisms mitigating competition or facilitating positive interactions between ecologically similar species are often poorly understood. Aardwolves (Proteles cristata) and aardvarks (Orycteropus afer) are nocturnal, insectivorous mammals that co‐occur in eastern and southern Africa, and knowledge of these species is largely limited to their nutritional biology. We used aardwolf and aardvark detections from 105 remote cameras during 2016–2018 to assess their spatial and temporal niche overlap in the grasslands of Serengeti National Park, Tanzania. Using a multispecies occupancy model, we identified a positive interaction between occupancy probabilities for aardwolves and aardvarks. Slope, proportion of grassland and termite mound density did not affect the occupancy probabilities of either species. The probability of aardwolf, but not aardvark, occupancy increased with distance to permanent water sources, which may relate to predation risk avoidance. Diel activity overlap between aardwolves and aardvarks was high during wet and dry seasons, with both species being largely nocturnal. Aardwolves and aardvarks have an important ecological role as termite consumers, and aardvarks are suggested to be ecosystem engineers. Our results contribute to a better understanding of the spatial and temporal niche of insectivores like aardwolves and aardvarks, suggesting high spatial and temporal niche overlap in which commensalism occurs, whereby aardwolves benefit from aardvark presence through increased food accessibility.
Small molecule inhibitors targeting regulatory T cells for cancer treatment
Authors: García‐Díaz Nuria , Wei Qian , Taskén Kjetil 
Published: November 2023

AbstractRegulatory T cells (Tregs) are important controllers of the immune system homeostasis by preventing disproportionate immune responses. In the context of cancer, Tregs contribute to tumor development by suppressing other immune cells in the tumor microenvironment (TME). Infiltration of Tregs in the TME has been associated with poor prognosis in cancer patients. Thus, understanding the mechanisms underlying Treg recruitment and suppressive functions is essential for developing cancer immunotherapies to boost antitumor immune responses. While antibody‐based strategies targeting Tregs have shown promise, small molecule inhibitors offer distinct advantages, including oral bioavailability and the ability to penetrate the TME and target intracellular proteins. Here, we provide an overview of small molecule inhibitors that have demonstrated efficacy in modulating Tregs activity in cancer and highlight the need for phenotypic assays to characterize therapeutic compounds.

Published: November 2023

AbstractEating disorders (EDs) present a chronic issue to child paediatric mental health services due to their high mortality and relapse rates. The transition from Child and Adolescent Mental Health Services to Adult Mental Health Services is a particularly high‐risk period for young people with EDs given their high vulnerability to change, which can negatively impact treatment outcomes. However, there is lack of evidence on the feasibility of inclusive and youth‐specific interventions that address the multiple and complex needs of this group during their transition to adult care. This proposed study aims to develop a newly introduced model of care called Transition for Eating Disorder Youth intervention (TEDYi) for young people aged 16–18 years with EDs transitioning from adolescent ED services to adult care. TEDYi will be co‐produced with young people, carers, and staff targeting interpersonal and psychosocial needs during the transition process. The first phase of the study involves interviews with young people (N = 15) and carers (N = 15) as well as focus groups with mental health professionals (N = 15) across four ED adolescent and adult specialist services to explore their transition experiences. The second phase, consists of four Experience‐Based Co‐Design workshops, aimed at collaboratively developing and refining TEDYi.

AbstractBackgroundNeck pain is a complex musculoskeletal disorder that can result in substantial morbidity. The present article presents the neck pain burden in Iranians who were at least 70 years old, from 1990 to 2019, by sex, age group, and province.MethodsPublicly available information on the prevalence, incidence, and years lived with disability (YLD) caused by neck pain was extracted from the Global Burden of Disease study 2019. The estimates were all provided as counts and age‐standardized rates (per 100,000), and included 95% uncertainty intervals.ResultsThe point prevalence of neck pain in 2019 was 8710.6, while the incidence rate was 1334.7 per 100,000 population. That same year, there were number of 27.8 thousand YLDs and an YLD rate of 801.7 per 100,000. The prevalence, incidence, and YLD rates did not change substantially over the measurement period (1990–2019). The highest YLD rate was found in Tehran (960.9 per 100,000), while Kohgiluyeh and Boyer‐Ahmad had the lowest (730.5 per 100,000). Females had slightly higher prevalent cases, incident cases, and YLDs, as well as their corresponding rates in 2019. In 2019, the number of prevalent cases, incident cases, and YLDs peaked in the 70–74 age group, for both sexes, and in all cases they reduced with age. In both 1990 and 2019, Iran had a higher YLD rate than that found among elderly adults in the Middle East and North Africa region.ConclusionsThe burden of neck pain in Iran has decreased slightly over the last three decades, but it still imposes a substantial burden and is higher than that found in the rest of the region. Therefore, preventive programs should be initiated at a young age to reduce the attributable burden later in life.

Published: November 2023

AbstractBackground and AimsLeukocytospermia (LCS) is a known cause of male infertility. However, the relationship between seminal leukocytes and semen quality among infertile couples remains controversial. This study aims to investigate the association between semen quality and LCS in male partners of infertile couples.MethodsSemen samples were collected from 512 men who asked for a fertility evaluation in a reproductive center in China. Seminal leukocytes were counted following peroxidase staining with benzidine. Other semen parameters were compared in subfertile men with and without LCS.ResultsPoor semen quality (e.g., low semen volume, sperm concentration, and sperm progressive/total motility) was observed among men with LCS compared to those without LCS. Men with LCS had a higher risk of low sperm progressive motility (OR = 0.99, 95% CI = 0.98−0.99, p = 0.02) and total motility (OR = 0.99, 95% CI = 0.98−0.99, p = 0.02), even after adjustment for potential confounders (both OR = 0.99, 95% CI = 0.98−0.99, p = 0.03). Lower sperm viability was observed in LCS from male partners of secondary couples, while no significant difference in semen parameters was found between men with and without LCS in male partners of primary infertile couples. Low sperm motility and viability were associated with LCS in men from secondary infertile couples after adjusting for confounders (OR = 0.97, 95% CI = 0.95−0.99, p = 0.04; OR = 0.94, 95% CI = 0.89−0.99, p = 0.04, respectively).ConclusionsOur findings indicate that a higher risk of abnormal semen parameters was correlated with an increased number of leukocytes in men from secondary infertile couples.

Published: November 2023

AbstractBACKGROUNDSemiconductor photocatalysts based on TiO2 nanoparticles were synthesized via the sol–gel method and subsequently modified using monometallic (Bi‐TiO2, Zn‐TiO2) and bimetallic (Bi/Zn‐TiO2) doping through the wet‐impregnation technique. The prepared photocatalysts underwent comprehensive characterization using X‐ray diffraction analysis, Fourier transform infrared spectroscopy, ultraviolet–visible diffuse‐reflectance spectroscopy, field emission scanning electron microscopy, photoluminescence, and thermal gravimetric analysis. The photocatalytic performance of these well‐characterized photocatalysts was assessed for the degradation of the model organic pollutant, nitrobenzene.RESULTSAmong the various doped TiO2 catalysts, Bi/Zn co‐doping at a ratio of 0.25:0.75 (w/w) exhibited the most remarkable synergistic effect, achieving approximately 82% degradation of a 50 ppm nitrobenzene solution within just 90 min of reaction time under ultraviolet light irradiation. The rate constant for this process was determined to be 1.79 × 10−2 min−1, suggesting a pseudo‐first‐order kinetics model.CONCLUSIONThe successful co‐doping of Bi and Zn metals to TiO2 resulted in improved photocatalytic performance. The enhanced performance could be attributed to the improved charge transfer facilitated by the synergistic effect among doped metals and TiO2. This finding highlights the significance of bimetallic doping and its potential applications in improving the photocatalytic efficiency of TiO2 nanoparticles for environmental remediation. © 2023 Society of Chemical Industry (SCI).
Analysis of the Imaginative Geographies of Climate Smart Mining and their re‐imagination by the Khuthala environmental care group (KECG) in Mpumalanga province, South Africa
Authors: Nair Sharmini 
Published: November 2023

AbstractThe World Bank has been inserting capital in various developing states at the onset of the decolonization period. The nature of this involvement within the context of extractives in these spaces remains understudied through the postcolonial lens. This study fills this void by examining the World Bank's Climate Smart Mining and counter‐responses by the Khuthala Environmental Care Group. Utilizing Said's Imaginative Geographies and discourse analysis, this study shows that the World Bank's CSM documents reproduce the development rhetoric of the 1950s and these values are not shared by local communities. This research suggests that the World Bank needs to substantively alter its agenda for meaningful social and ecological reform.
