Published: May 2024

In this study, we introduce an effective strategy to prepare electrodes containing new nanocomposites with high specific capacity. This research led to the preparation of CoFe2‐xCexO4/rGO‐Pani nanocomposite with an extraordinary specific capacitance of 3257.83 F·g−1 (at 10 mV·s−1), a power density of 349.951 W/kg, and an energy density of 3.52 Wh/kg. Also, electrical conductivity studies for new nanocomposite showed good electrical conductivity and better semiconducting properties compared with its similar compounds. Also, the synthesized compounds were characterized and identified by other analyses. FT‐IR analysis for reduced graphene oxide showed that graphene oxide was well reduced. It also confirmed the presence of Ce‐O for both CoFe2‐xCexO4/rGO‐Pani and CoFe2O4‐CeO2/rGO‐Pani magnetic nanocomposites. XRD analysis confirmed the crystal structure for rGO, CoFe2‐xCexO4/rGO‐Pani, and CoFe2O4‐CeO2/rGO‐Pani. VSM analysis was done to check the magnetic properties of the nanocomposite, and the magnetic values were measured as expected. In the following, morphological studies and the uniformity of distribution of elements in magnetic nanocomposite were carried out with FE‐SEM and Map, respectively.

AbstractThe separation process is a well‐established method for beneficiation technologies of low‐rank coal, especially in the case of utilization in the thermochemical processes. In this study, three coal samples, including the original low‐rank coal sample and two coal samples (C1 and C2) from the gravity separation process of the original coal sample, were gasified in a multi‐stage gasification process at the gasification temperature of 900°C and the steam‐to‐carbon (S/C) ratio of 1.00 and 1.25. The separation process led to a significant improvement in the quality of coal samples. This improvement is particularly characterized by a higher carbon and volatile fractions and a lower ash content compared with the original coal. This could be the main reason for the higher gasification performance in the case of the experiment of C1 and C2 coal samples. The volume of syngas obtained from gasification experiments of C1 and C2 samples increased between 1.3 and 1.5 times that of the original coal sample. At all S/C ratios and 900°C, the gasification experiment of the C2 sample produced the highest produced gas yield followed by the gasification experiment of the C1 sample. From the chemical point of view, the produced gas had an H2/CO ratio close to the desired ratio of 2.00, which is suitable for chemical synthesis processes. In the case of C1 sample experiments, the H2/CO ratios were 2.11 and 2.18 at S/C ratios of 1.00 and 1.25, respectively. For the experiments of the C2 sample, the H2/CO ratio reached 1.88 and 2.00 at S/C ratios of 1.00 and 1.25, respectively.

AbstractCorneal diseases are a significant cause of visual impairment and blindness. The first‐line treatment for corneal opacity is penetrating keratoplasty (human donor cornea transplantation). At present, keratoprosthesis (KPro), an artificial cornea, is the last resort for correcting end‐stage corneal blindness and is usually supported by donor tissue. This article describes a new intralamellar tissue‐free KPro design concept and its preparation method. Wherein, an injection‐molding route is adopted to create a mechanically and structurally stable near‐KPro geometry using a photo‐polymerized poly(2‐hydroxyethyl methacrylate) (pHEMA) with 4% Bisphenol A dimethacrylate (BisMA) crosslinked (PC4) hydrogel composition. Prior to this, the physico‐mechanical properties of crosslinked hydrogels matching corneal tissue are identified, and the surface morphological characteristics of silk cocoon membranes are ascertained in choosing suitable KPro materials. Cytocompatibility tests on PC4 and silk‐incorporated PC4 hydrogels using rabbit corneal fibroblast cell‐line evidenced enhancement in cell growth on silk‐PC4 surfaces. Furthermore, near KPro geometry is surface‐profiled to create a one‐of‐a‐kind design with clear optics and a silk‐bioactivated composite‐based haptic‐flange hydrogel network containing site‐specific submillimeter‐scale perforations to improve tissue integration. Considering this unique KPro geometry, the optic‐haptic‐flange construct is a tissue‐free semi‐bioresorbable hydrogel device presumed to provide stability under the influence of intraocular pressure (IOP) and eyelid shear. Through this study, it is identified new KPro materials facilitate significant cytocompatibility while complimented with site‐specific novel design would offer tissue ingrowth with gradual resorption of silk, leaving behind a stable intralamellar tissue integrated with hydrogel when implanted in the corneal niche.

Published: May 2024

AbstractThis study synthesized polydimethylsiloxane (PDMS)‐modified polyaspartate polyurea (PPPU) with different ratios, considering the practical performance requirements of underground water supply pipeline spray repair materials. The successful synthesis of PPPU was confirmed using Fourier transform infrared spectrometer (FTIR) spectroscopy. The influence of the ratio of the two components and the content of ‐aminopropyl terminated polydimethylsiloxane (APT‐PDMS) on the drying time and tensile performance of PPPU coatings was evaluated. Based on this evaluation, a superior ratio for PPPU coatings was proposed. Subsequently, the bonding performance, hydrophobicity, and corrosion resistance of PPPU coatings at the superior ratio were tested. The results indicate that as the mass ratio of polyaspartic acid ester to hexamethylene diisocyanate trimer increases, both the drying time and tensile strength of the coating decrease. The addition of APT‐PDMS results in a decrease in the tensile strength of PPPU, but an increase in its elongation at break. The peak value of elongation at break is achieved when the APT‐PDMS content is 5%, making the PPPU2‐1‐5 coating the superior ratio for spray application on water supply pipelines. Through experiments, it was determined that the bonding strength of the PPPU2‐1‐5 coating with cement mortar under dry and humid conditions, static water contact angle (93.4°), and corrosion resistance performance are superior to those of the unmodified polyurea coating, demonstrating its application advantages. The conclusions drawn in this study provide a theoretical foundation for the practical engineering application of PPPU.
Inclusive global scholarly communication: Toward a just and healthier information ecosystem
Authors: Ford Angel Y. , Alemneh Daniel G. 
Published: May 2024

AbstractScholarly communication has long been a central topic in the field of information science. However, philosophical, and even perhaps some legal reflections, including the moral and ethical considerations of the health of information ecosystems, are fairly recent developments. In fact, recent topics are propelled by various contextual factors including economic, disciplinary, societal norms, and cultures. This article explores literature discussing the plight of scholars in low‐ and middle‐income countries that struggle to engage in scholarly communications in their fields. This topic has been explored for years, however, has often been addressed in disciplines outside of information science and knowledge management. This study posits that critical investigations lift this issue to one of justice and suggest a new critical lens that would rely on several existing lenses, including those developed to expand epistemic injustice, as well as exploring areas and perspectives that have not yet found their way into the mainstream literature. The analysis provides alternative approaches and discourse around the democratization of scholarly communications, all toward achieving a just and healthier global information ecosystem.

Published: May 2024

AbstractActivated carbon is an attractive adsorbent for capturing various environmental pollutants, including CO2. Herein, an optimal synthesis and impressive performance of activated carbon made from Balanites aegyptiaca (Desert date) seed shells is reported, which is an abundant agricultural waste in the Middle East and Africa. The synthesis route involved pretreating the biomass with KOH and heating it under a suitable temperature profile. An optimal KOH‐to‐biomass ratio and multi‐stage carbonization yielded activated carbon with a surface area above 3000 m2/g and an average pore size of nearly 4.1 nm. At 0 °C, this activated carbon exhibited CO2 uptake of 11.3 mmol g−1 that surpassed the uptake capacity of previously reported activated carbons. The selectivity towards CO2 was also found to be significantly higher compared to other gases. Thus, the present approach demonstrates an efficient conversion of agricultural waste to activated carbon for capturing CO2 and other environmental contaminants.
Metal Ion Responsive Luminescent Bio‐Templated Co‐Assemblies: Label‐Free Detection of Multi‐Metal Ions in Aqueous Media

Published: May 2024

AbstractRecently, anionic bio‐templates have emerged as promising platforms for designing dynamic and stimuli‐responsive chromophoric assemblies capable of light harvesting in aqueous media thereby mimicking natural photosynthesis. Here, we present multi‐metal ion‐responsive luminescent co‐assemblies between cationic pyrene‐imidazolium amphiphile and anionic bio‐templates (ATP, heparin, and DNA) in aqueous media. The anionic bio‐templates enhance Förster resonance energy transfer (FRET) in the co‐assemblies, with pyrene serving as an excellent donor for generating tunable multi‐luminescent materials with embedded acceptor dyes. However, a significant loss in energy transfer towards acceptor dyes was observed in the presence of various metal ions, attributed to excimeric emission quenching facilitated by electron transfer between the pyrene chromophore and metal ions. Interestingly, detailed studies revealed that only ATP‐based co‐assemblies exhibited quenching phenomena in the presence of metal ions, contrasting with heparin and ctDNA co‐assemblies. Additionally, label‐free detection of multi‐metal ions in aqueous environments, such as Fe2+, Fe3+, and Cu2+ ions, was successfully achieved with lower detection limits of 0.01 μM (3 ppb), 0.12 μM (30 ppb), and 0.58 μM (150 ppb) respectively. These co‐assemblies hold significant promise for practical applications in environmental and biomedical sensing, enabling sensitive monitoring of metal ion concentrations.

Published: May 2024

AbstractThis article presents accelerated failure time models with and without frailty for modeling multiple systems subject to minimal repair. The study considers the conventional accelerated failure time model, the accelerated failure time model with Gamma frailty, and proposes the accelerated failure time model with weighted Lindley frailty, which has attractive properties such as a closed‐form Laplace transform. The proposed model extends the accelerated failure time model with the intensity function of a power law process. It retains the direct physical interpretation of the original accelerated failure time model, in which the role of covariates is to accelerate or decelerate the time to each repair. This framework includes parametric approaches to model fitting, which we consider for estimating the vector of regression parameters under this model and the parameter in the baseline intensity functions. The methodology is illustrated with a simulation study and a toy example to demonstrate the applicability of these models in the industrial context.
Proud to Be Dishonest: Emotional Consequences of Altruistic Versus Egoistic Dishonesty
Authors: Shuster Shaked , Eyal Tal , Ayal Shahar , Moran Simone 
Published: May 2024

ABSTRACTWe explore and demonstrate the anticipated and actual emotions that are experienced by individuals who engage in dishonest behaviors that benefit others (altruistic dishonesty) versus the self (egoistic dishonesty), and primarily focus on the positive emotion of pride. Across three preregistered experiments (one scenario experiment and two incentivized behavioral ones), we found that engaging in altruistic dishonesty was not only more prevalent than egoistic dishonesty but also evoked more pride and less guilt and shame. Interestingly, the increase in pride and decrease in guilt and shame when cheating solely for the benefit of others were attenuated when participants cheated for the benefit of both others and themselves. These findings shed further light on the emotional processes involved in dishonesty and highlight the understudied role of pride. The positive association between engaging in altruistic dishonesty and pride may explain the relatively high rates of altruistic dishonesty observed in the current and previous studies, as it suggests that having an altruistic justification may not only enable cheaters to maintain a clear conscience but also even boost how they feel about themselves.

Published: May 2024

AbstractColloidal semiconductor quantum dots have many potential optical applications, including quantum dot light‐emitting diodes, single‐photon sources, or biological luminescent markers. The optical properties of colloidal quantum dots can be affected by their dielectric environment. This study investigated the photoluminescence (PL) decay of thick‐shell gradient‐alloyed colloidal semiconductor quantum dots as a function of solvent refractive index. These measurements were conducted in a wide range of delay times to account for both the initial spontaneous decay of excitons and the delayed emission of excitons that has the form of a power law. It is shown that whereas the initial spontaneous PL decay is very sensitive to the refractive index of the solvent, the power‐law delayed emission of excitons is not. Our results seem to exclude the possibility of carrier self‐trapping in the considered solvents and suggest the existence of trap states inside the quantum dots. Finally, our data show that the average exciton lifetime significantly decreases as a function of the solvent refractive index. The change in exciton lifetime is qualitatively modeled and discussed.

AbstractBackgroundAnamorelin was approved in Japan in 2021 to treat cancer cachexia associated with non‐small cell lung, gastric, pancreatic, or colorectal cancers. Post‐marketing surveillance is being conducted to evaluate the real‐world safety and effectiveness of anamorelin.MethodsThis prospective, observational surveillance registered all patients who started treatment with anamorelin after April 21, 2021. Hyperglycemia, hepatic impairment, conduction disorders, and their associated adverse events related to treatment were defined as main safety specifications. Body weight (BW) and appetite were assessed as effectiveness specifications.ResultsThis analysis was based on data as of January 21, 2023. The safety and effectiveness analysis sets included 6016 and 4511 patients, respectively. Treatment‐related adverse events in ≥1% of patients were hyperglycemia (3.9%) and nausea (2.6%). The incidences of hyperglycemia, hepatic impairment, conduction disorders, and their associated adverse events related to treatment were 4.8%, 1.2%, and 1.1%, respectively. The mean changes (standard error [SE]) in BW from baseline to weeks 3, 12, 24, and 52 were 0.64 (0.05) kg, 1.19 (0.12) kg, 1.40 (0.21) kg, and 1.42 (0.39) kg, respectively. The mean changes (SE) in Functional Assessment of Anorexia/Cachexia Treatment 5‐item Anorexia Symptom Scale total scores from baseline to weeks 3, 12, 24, and 52 were 3.2 (0.09), 4.8 (0.18), 5.2 (0.30), and 5.3 (0.47), respectively, exceeding the clinically meaningful improvement score (2.0 points).ConclusionThe overall safety of anamorelin raised no new safety concerns, although continued caution may be required for hyperglycemia and nausea. Improvements in BW and appetite were also observed in real‐world clinical settings.

Published: May 2024

AbstractCarbon dioxide (CO2) is a greenhouse gas which is mainly found in natural gas (NG), biogas, and flue gas. Anthropogenic CO2 emissions are the direct result of burning fossil fuels. Meanwhile, pre‐ and postcombustion CO2 separation is a current state of CO2 removal method in an extensive manner. From environmental, economic, and transportation perspectives, removal of CO2 has driven the development of its separation process technology. Among the reported technologies, membrane‐based gas separation technologies have grown substantially, breakthroughs and advances in past decades. This review paper aims to provide an overview on competitive gas separation processes, different types of membranes available, gas transport mechanisms, and fabrication process of hollow fiber membranes, particularly dual‐layer hollow fiber membrane. The performance of the membranes in CO2 separation and effect of spinning parameters on the formation of hollow fiber membranes are highlighted. In addition, approaches to improve the dual‐layer adhesion, strategies to enhance the filler compatibility in the development of dual‐layer hollow fiber mixed‐matrix membranes, and effect of post‐treatments on the gas separation performance of membrane are also discussed. Finally, challenges and future perspectives of dual‐layer hollow fiber mixed‐matrix membranes toward CO2 capture, particularly on CO2/CH4 and CO2/N2 separation, are also included, due to its substantial and direct relevance to the gas separation industry.

AbstractThis work investigates the efficiency of cholecalciferol and low dose gamma radiation in modulating cytokine storm through their impact on inflammatory and anti‐inflammatory cytokine and protecting against lung and liver injuries. Male Swiss albino mice were exposed to 0.2 Gy gamma radiation/week for four consecutive weeks then injected intraperitoneally (i.p) with a single dose of 8.3 × 106 CFU Escherichia coli/g b.w. then injected i.p. with 1.0 mg/kg cholecalciferol (Vit D3) for 7 days starting 4 h after E. coli injection. The results revealed that Cholecalciferol and low dose gamma radiation caused significant depletion in the severity of E. coli infection (colony forming unit per milliliter), log10 of E. coli, Tumor necrosis factor alpha, Interleukin 6, VEGF, alanine aminotransferase, and aspartate aminotransferase levels and significant elevation in IL‐10, IL‐4, and HO‐1. Immunohistochemical analysis of caspase‐3 expression in lung tissue section showed low caspase‐3 expression in cholecalciferol and low dose gamma radiation treated group. Histopathological examinations were performed in both lung and liver tissues which also emphasis the biochemical findings. Our results exhibit the importance of cholecalciferol and low dose gamma radiation in improving liver function and providing anti‐inflammatory response in diseases causing cytokine storm.

Pedicle ossification after fibular flap reconstruction of maxillary defects: A case report and literature review
Authors: Zou Bo 
Published: May 2024

Key Clinical MessageThe phenomenon of vessel pedicle ossification is a noteworthy aspect of the repair and reconstruction of maxillofacial defects. Imaging findings typically reveal high‐density shadows within the vascular pedicle pathway, which may be managed through conservative observation or surgical intervention as deemed appropriate.AbstractVessel pedicle ossification is a relatively uncommon complication associated with the reconstruction of oral and maxillofacial tissue defects using free tissue flap repair. In this paper, we report a case of pedicle ossification and conduct a comprehensive review of previous literature. A 39‐year‐old man presented with a limited ability to open his mouth 6 months after fibular flap reconstruction of the mandible. Plain film X‐ray and computed tomography (CT) indicated pedicle ossification. Two years after the initial operation, the restriction in the patient's ability to open his mouth had not worsened, although there were more pronounced radiographic abnormalities.
