Sharia Bank is a financial institution tasked with collecting funds and distributing funds as well as providing other services based on the principles of partnership, fairness, transparency and universality as well as conducting banking business activities based on sharia principles. The development of Islamic banks is currently quite fast, but lately Islamic bank customers have different perceptions of Islamic banking, where some people hear about news or issues circulating about the perception of public figures who say that Islamic banks still use the principle of usury. which is a benchmark for some people and raises its own doubts about saving in Islamic banks, this is caused by several factors. First, the lack of socialization carried out by Islamic banks. Second, the lack of understanding of public figures regarding the system and objectives of Islamic banking itself.
The formulation of the problem in this research is how is the perception of community leaders in increasing people's interest in saving?
This type of research is a field research (field research), and is descriptive qualitative. The results of this study state that the perception of public figures in increasing public interest in saving in Islamic banks is in the Good category. Good category, customers already understand what Islamic banking is like, customers already know Islamic banks and not a few customers who already understand Islamic banking, and the public confirms that there are issues circulating in the community where public figures still have the assumption that Islamic banks are no different from conventional banks, while the issue of usury on people's interest in saving Islamic banks is in the medium category, meaning that the issue of usury circulating among the public has quite an impact on people's perceptions, therapy does not have much impact on people's interest in saving.

Background: Superficial fungal infections (SFIs) are common and have considerable negative impact on school children in tropics.
Objectives: The study compared the prevalence and pattern of SFI among primary school pupils in an agrarian (Ukpor) and commercial (Nnewi) communities in Nnewi Area.
Methodology: A cross-sectional study was conducted among primary school pupils in Nnewi Area. Subjects were selected using stratified random sampling technique. Data was analyzed using SPSS version 21.
Results: Final analysis involved 773 and 789 pupils in the agrarian and commercial communities, respectively. Their mean age was 9.0 ±2.0 years and male: female ratio was 1:1. The agrarian community had a significantly higher proportion of children who were from low socio-economic class families, and had poorer hygiene practices (p=0.000). The overall prevalence of SFIs was 28.9%. Prevalence was significantly higher in the agrarian compared to commercial community (39.3% versus 18.6%; p = 0.000). Tinea capitis was the predominant form of SFIs accounting for 80.3% and 83.7% of SFIs cases in the agrarian and commercial communities, respectively. Black dot tinea capitis was the commonest variant of tinea capitis in both communities. Of the variants of tinea capitis, only the diffuse scale type differed in the rate of occurrence in the two communities (6.3% in agrarian versus 0.0% in commercial communities, p=0.023). The most prevalent organisms were T. tonsurans (37.9%), T. mentagrophytes (28.8%) and T. rubrum (18.7%) of which T. rubrum was significantly higher in the commercial community (27.6% versus 14.9%, p=0.036).
Conclusion: The burden of SFI is high among primary school children in Nnewi area, especially among those in agrarian communities. More awareness should be created on the prevention, identification and treatment.

AbstractPurposeStudies on deep learning dose prediction increasingly focus on 3D models with multiple input channels and data augmentation, which increases the training time and thus also the environmental burden and hampers the ease of re‐training. Here we compare 2D and 3D U‐Net models with clinical accepted plans to evaluate the appropriateness of using less computationally heavy models.MethodsA 2D Attention U‐Net, a 2D HD U‐Net, and a 3D U‐Net were trained using 1 or 5 input channels with or without data augmentation and data from 89 locoregional breast cancer patients. Results were compared to clinically accepted plans. The significance of inclusion of more channels or data augmentation was compared to the base models and the HD U‐Net and Attention U‐Net were compared to their respective identically trained counterparts.ResultsThe Attention U‐Net reached fewest PTV clinical goals (28%, mostly due to a too high average breast PTV dose) and improved using significantly using five channels and augmentation (49%). The HD U‐Net already fulfilled 70% of the PTV goals, which did not improve much by adding more channels or augmentation. The 3D U‐Net with five channels and augmentation reached 76%, compared to 81% in the clinically accepted plans. The lower rates for the HD U‐Net compared to the 3D U‐Net and clinical plans were mainly caused by a lower PTVn1n2 D98%, which was still on average 93%. Organ‐at‐risk goals were met in most cases for all models. Training time was approximately 8 fold for the 3D model.ConclusionsComparable results to a 3D U‐Net and clinical plans can be reached with a 2D HD U‐net for a dataset size commonly seen in clinical practice. The Attention U‐Net did profit from adding extra channels and data augmentation but did not reach the same level of accuracy as the other models.

In the article, microstructure, texture, and room‐temperature mechanical properties of the hot‐extruded Mg‐2.35Nd‐1.32Gd‐0.18Zn‐0.32Zr alloy sheet subjected to cold rolling and subsequent aging heat treatment are investigated. It is found that the extruded experimental alloy sheet exhibits homogeneous microstructure and extrusion direction‐split texture, and approaching room‐temperature mechanical properties along extrusion and transverse directions. The rare‐earth texture component deflects toward the basal texture component, resulting in a relative mitigation of texture differences between extrusion and transverse directions after cold rolling. Subsequent aging heat treatment significantly alleviates severe stress concentration near the grain boundaries, and precipitates many fine β1 phase within grains. The yield strength and ultimate tensile strength in the extrusion direction of extruded experimental alloy sheet significantly increase from 150 and 230 MPa to 312 and 347 MPa after cold rolling and subsequent aging heat treatment, respectively. Meanwhile, the yield strength ratio between extrusion and transverse directions improve from 0.92 to 1.03, which is mainly attributed to the texture evolution and the different strengthening effects of the β1 precipitates on basal <a> and prismatic <a> dislocations. Grain boundary and precipitation strengthening are inferred as the dominant strengthening mechanisms, accounting for about 75% to the yield strength.

AbstractThe shuttle effect and sluggish reaction kinetics of soluble lithium polysulfides (LiPSs) significantly impede the practical application of lithium‐sulfur (Li‐S) batteries. Topological semimetals (TSMs) offer a promising solution to these challenges due to their unique topological surface states. This study synthesizes reduced graphene oxide (rGO)‐loaded Pd3Sn TSMs (Pd3Sn@rGO) that are prepared by the NaBH4 reduction method. The obtained Pd3Sn@rGO composite has a notably stronger adsorption capability for LiPSs than pure rGO verified by adsorption experiments and density functional theory (DFT) calculations. The topological surface states of Pd3Sn facilitate the acceptance of electrons from Li2S6 during the adsorption process, thereby enhancing adsorption and accelerating redox reactions. Furthermore, Li2S deposition experiments confirm the effective catalytic role of Pd3Sn@rGO in the nucleation process of Li2S. Consequently, Li‐S batteries with Pd3Sn@rGO modified separators showcase exceptional rate performance across various current densities along with impressive cycling stability (decay rate of 0.0598% per cycle at 1C). This work highlights the capability of Pd3Sn in catalyzing sulfur redox reactions and underscores the potential of other TSM electrocatalysts in enhancing the performance of Li‐S batteries.

AbstractCarbon dots (CDs) are emerging as promising nanomaterials for next‐generation white electroluminescent devices due to their high photoluminescence quantum yield (PLQY), broad emission spectrum, and compatibility with solution‐processed methods. However, current CD‐based white light‐emitting diodes (CDs‐WLEDs) heavily rely on costly commercial host materials and struggle with low color rendering index (CRI). Herein, a “dual‐phase CDs emitter” strategy is introduced to achieve full‐spectrum white light emission, without employing commercial host materials. As a proof of concept, CDs are synthesized with broadband green emission and nearly 100% PLQY. Spectroscopic and structural analyses confirm that their luminescence originates from molecular state emission. By combining these green CDs with carbon quantum dot organic frameworks capable of dual blue and red emissions, white light is successfully produced with a record CRI of 94 and color coordinates of (0.32, 0.34). This approach provides a cost‐effective and efficient pathway for developing high‐performance WLEDs that rely exclusively on CDs.

AbstractAdvancing energy conversion technologies requires cost‐efficient electrocatalysts for the oxygen reduction reaction (ORR). Iron phthalocyanine (FePc) emerges as a scalable and economical ORR electrocatalyst. However, the Fe–N4 configuration in FePc still falls short of the satisfied ORR activity and stability under electrocatalytic conditions. Here, an effective f‐p‐d (Eu–O–Fe) gradient orbital coupling strategy is introduced by integrating FePc with Eu2O3 (FePc/Eu2O3) to enhance the spin state and ORR performance of the Fe center through a precisely designed, scalable synthetic approach. The Eu─O bond promotes electron delocalization and shifts the spin state of Fe center from low‐spin to intermediate‐spin, increasing the eg​ orbital occupancy. This modification optimizes the adsorption of oxygen‐containing intermediates and lowers the ORR energy barrier. Notably, the increased spin state of Fe accelerates charge transfer by releasing more unpaired electrons, improving reaction kinetics. Furthermore, the f‐band serves as a buffer layer for electron compensation during ORR, further stabilizing the covalency and electronic configuration of atomic Fe and boosting durability. The one‐batch synthesis produces exceeding 300 g of FePc/Eu2O3, achieving a half‐wave potential of 0.931 V (vs RHE) at a cost less than 1/15 of commercial Pt/C. It demonstrates exceptional ORR performance in aluminum–air batteries, highlighting its significant application potential.

Abstract2D materials exhibit unique properties for next‐generation electronics and quantum devices. However, their sensitivity to temperature variations, particularly concerning cooling‐induced strain, remains underexplored systematically. This study investigates the effects of cooling‐induced strain on monolayer MoSe2 at cryogenic temperatures. It is emphasized that the mismatch in thermal expansion coefficients between the material and bulk substrate leads to significant external strain, which superimposes the internal strain of the material. By engineering the material‐substrate 2D‐bulk interface, the resulting strain conditions are characterized and reveal that substantial compressive strain induces new emission features linked to direct‐to‐indirect bandgap transition, as confirmed by photoluminescence and transient absorption spectroscopy studies. Finally, it is demonstrated that encapsulation with hexagonal boron nitride can mitigate the external strain by 2D–2D interfaces, achieving results similar to those of suspended samples. The findings address key challenges in quantifying and characterizing strain types across different 2D‐bulk interfaces, distinguishing cooling‐induced strain effects from other temperature‐dependent phenomena, and designing strain‐sensitive 2D material devices for extreme temperature conditions.

Published: February 2025

AbstractThe challenges of operating robots in natural, highly variable, and diverse physical environments demand equally variable solutions. Following a flexible design approach from soft robotics, a variable stiffness structure with shape morphing and shape memory capabilities made from layered textiles and 3D printing material is developed. The stiffness change of the central conductive PLA (cPLA) is achieved electrically via Joule heating. Fabrication of multiple segment surfaces from the textile materials allows for direct printing of cPLA, which maximizes the electrodes' contact area. The material's variable stiffness is then used to modulate the structure's bending behavior and actively change its shape (shape morphing) while preserving shape memory behavior. To achieve this, models for stiffness change, heat transfer, and shape morphing are introduced and tested experimentally. The design presents a new method for achieving variable stiffness of 2794 Nmm2 in small segments of soft, deformable structures, using widely available materials and simple manufacturing methods. Furthermore, the structure's design enables shape morphing and shape memory.

AbstractThis study focuses on optimizing MoS₂ catalysts for the hydrogen evolution reaction (HER) in anion exchange membrane (AEM) electrolyzers. A scalable Ionized Jet Deposition (IJD) technique is employed to deposit MoS₂ onto various carbon supports, exploring the relationship between substrate properties and catalytic performance. The results demonstrate that substrate choice plays a pivotal role in enhancing HER activity and durability. MoS₂ deposited on Freudenberg carbon support exhibited the best catalytic activity, achieving a current density of 10 mA µg⁻¹Mo at −0.48 V versus RHE in an alkaline environment, even with a low catalyst loading (12–49 µg cm⁻2). Conversely, sulfur‐doped carbon supports showed lower HER activity but superior stability, with a minimal voltage degradation of just 0.025 V after 6 h of testing at 10 mA cm⁻2. To further understand these results, bubble evolution studies, and contact angle measurements are conducted. Stable electrodes demonstrated small contact angles and enhanced bubble release from the surface, indicating the importance of hydrophilicity in improving performance and durability. This work highlights the synergy between scalable synthesis techniques and substrate optimization, offering a promising path for advancing cost‐efficient, durable electrocatalysts in large‐scale AEM electrolyzers for green hydrogen production.

AbstractNew anodic electrocatalysts with high performance and cost‐effectiveness at large current densities help advance the emerging anion exchange membrane water electrolyzer (AEMWE) technology. To this end, a ruthenium (Ru) single atoms and sulfur (S) anions dual‐doped NiFe layered double hydroxides (Ru‐S‐NiFe LDH) catalyst is reported with remarkably low alkaline oxygen evolution reaction (OER) overpotentials, high mass activities and prolonged stabilities at high current densities. Inspiringly, the AEMWE performance on Ru‐S‐NiFe LDH is also superior to the NiFe LDH. In‐depth mechanism investigations reveal that Ru single atoms not only act as the highly active sites, but also facilitate the conductivity of NiFe LDH. Meanwhile, S anions accelerate the electrochemical reconstruction of NiFe LDH to OER‐active NiFeOOH and alleviate the over‐oxidation issue on Ru active sites. Benefiting from these, Ru‐S‐NiFe LDH shows significantly enhanced OER activity and stability. Theoretical calculations further validate the decreased OER free energy difference brought about by the Ru single atoms and S anions dual‐doping. This study offers a proof‐of‐concept that the noble metal single atoms and anions dual‐doping is a feasible strategy to construct the promising 3d transition metal‐based electrocatalysts toward the practical alkaline water electrolyzer.

AbstractObjectivesThe transition from residency to unsupervised practice challenges doctors to adapt to new environments and responsibilities. Past work has focused on how physicians acclimate to their new roles, raising questions about how residents might think proactively about transitions while still in training. This study explores senior emergency medicine (EM) residents’ perspectives on preparedness for unsupervised practice and how they draw from training experiences to assess their evolving sense of preparedness.MethodsThe authors used a constructivist grounded theory approach, inviting all fourth‐year EM residents from two residency programs to participate in semistructured interviews. Participants were asked to reflect on their preparedness for entering unsupervised practice and to imagine scenarios for which they felt unprepared. Two authors coded line by line using constant comparison, organizing data into codes and categories. The research team met to discuss relationships between codes, developing themes to theorize about the phenomenon of interest.ResultsSixteen residents were interviewed. The authors identified two overarching categories of themes. First, participants described individualized conceptualizations of preparedness, constructed from past workplace experiences and those they anticipated they would have in unsupervised practice. These conceptualizations emphasized drawing confidence from experience and developing adaptability to manage the uncertainties of medical practice. The second overarching category involved participants’ efforts to gauge their own preparedness. To do so, they used interactions with others to assess their readiness to manage specific problems and made holistic appraisals across multiple experiences to assess their overall preparedness for unsupervised practice.ConclusionsTrainees draw from past experiences to forecast their abilities to manage the inevitable uncertainties of unsupervised practice. These conceptualizations of preparedness reflect a capability approach to training, with informed confidence and dynamic self‐appraisal. These findings suggest potential learning goals of senior trainees and considerations for medical educators to consider when fostering trainees’ capabilities for unsupervised practice.
