AbstractThe rapid advancement of smart, flexible electronic devices has paralleled a surge in electronic waste (e‐waste), exacerbating massive resource depletion and serious environmental pollution. Recyclable materials are extensively investigated to address these challenges. Herein, this study designs a unique polyurethane (SPPUs) with ultra‐high strength up to 60 MPa and toughness of 360 MJ m−3. This synthetic SPPUs can be fully recycled at room temperature by using green solvents of ethanol. Accordingly, the resultant SPPU‐Ni composites, created by mixing the ethanol‐dissolved SPPUs solution with nickel (Ni) powder, effectively combine the flexibility and recyclability of SPPUs with the electrical conductivity of the nickel filler. Notably, this work develops the printable capacitive sensors (PCBS) through transcribing the paste of SPPUs‐Ni slurry onto PET film and paper using screen‐printing technology. The devised PCBS have fast response time ≈50 ms, high resolution, and multiple signal recognition capabilities. Remarkably, SPPUs and Ni powder can be fully recycled by only dissolving the waste PCBS in ethanol. This work offers a sustainable solution to the growing e‐waste problem in recyclable flexible electronics.

AbstractThe construction of sub‐nanometer cluster catalysts (<1 nm) with almost complete exposure of active atoms serves as a promising avenue for the simultaneous enhancement of atom utilization efficiency and specific activity. Herein, a core–shell cobalt‐cerium bimetallic oxide protected by high coverage sub‐nanometer Ir clusters (denoted as Ir cluster@CoO/CeO2) is constructed by a confined in situ exsolution strategy. The distinctive core–shell structure endows Ir cluster@CoO/CeO2 with enhanced intrinsic activity and high conductivity, facilitating efficient charge transfer and full‐pH water splitting. The Ir cluster@CoO/CeO2 achieves low overpotentials of 49/215, 52/390, and 54/243 mV at 10 mA cm−2 for hydrogen evolution reaction/oxygen evolution reaction (HER/OER) in 0.5 m H2SO4, 1.0 m PBS, and 1.0 m KOH, respectively. The small decline in performance after 300 h of operation renders it one of the most effective catalysts for full‐pH water splitting. DFT calculations indicate that oriented electron transfer (along the path from Ce to Co and then to Ir) creates an electron‐rich environment for surface Ir clusters. The reconstructed interface electronic environment provides optimized intermediates adsorption/desorption energy at the Ir site (for HER) and at the Ir‐Co site (for OER), thus simultaneously speeding up the HER/OER kinetics.

Published: October 2024

AbstractDiabetic wounds, characterized by complex pathogenesis and high infection rates, pose significant challenges in treatment due to prolonged recovery times and high recurrence rates, often leading to severe complications such as amputation and death. Traditional dry dressing treatments fail to address the unique microenvironment of diabetic wounds and tend to cause secondary damage due to frequent replacement. In this study, an electronic‐embedding, drug‐loading hydrogel bioelectronics is reported for accelerating diabetic wound healing using a combination of programmable pharmaceutical and electrostimulative approaches. Encapsulated in stretchable and biocompatible materials, this device is capable of multiple drug refilling and accelerated drug release modulated by on‐board electronics. In vivo experiments on diabetic model rats confirm the device's effectiveness in promoting wound healing. This innovative approach implies the potential for improving diabetic wound management using a combination of physical, material, and pharmaceutical interventions.

Published: October 2024

AbstractThe capture of radioactive iodine species from nuclear waste is crucial for environmental protection and human health. Porous organic cages (POCs), an emerging porous material, have showed potential in iodine adsorption due to the advantages of tunable pores and processibility. However, integrating multiple desirable characteristics into a single POC through bottom‐up assembly of pre‐designed building blocks remains challenging. Post‐synthetic modification (PSM) offers an alternative approach, enabling the introduction of various functions into a single POC. Herein, a viable and highly efficient three‐step PSM strategy to modify a representative POC (CC3), is presented. The modified POC, OFT‐RCC36+6Br−, features a charged confined space, electron‐rich heteroatom, and halide ions, exhibiting significantly enhanced iodine vapor uptake compared to the parental cage. The universality of the PSM strategy has been verified by successfully modifying two other POCs. The iodine adsorption behaviors of three modified cage adsorbents in organic solvent and aqueous solution have also been investigated, all of which exhibited improved performance, especially in comparison to ionic cages modified through direct protonation. This work provides an effective PSM strategy for POCs to facilitate iodine adsorption. More importantly, the introduction of a new PSM strategy enriches the functional diversity of POCs, potentially broadening their future applications.

AbstractThe presence of Griffiths phase to cluster spin glass transition has theoretically been predicted in both classical and quantum systems. However, its detection in a classical system has been lacking for decades, which hinders a complete understanding of the relationship between the Griffiths phase and cluster spin glass. Here, the experimental discovery of the Griffiths phase to cluster spin glass transition is reported in a classical magnetic system, diluted ferromagnets La2/3Sr1/3(Mn1‐3xAl2xTix)O3 (0 ≤ x ≤ 0.12). The phase diagram of the system shows a transition from the Griffiths phase into a ferromagnetic state in the low disorder concentration range (0.01 < x ≤ 0.09). In the high disorder concentration range (0.09 < x ≤ 0.12), a Griffiths phase to cluster spin glass transition is identified, which nicely matches that of disordered quantum systems. Moreover, the Griffiths phase is essentially an unfrozen cluster spin glass with partially broken ergodicity is demonstrated experimentally. These findings serve as crucial experimental references for understanding the glassy phenomena in disordered magnets, facilitating future exploration of their unique properties and functionalities.

Published: October 2024

AbstractAccurate identification and isolation of target cells are crucial for precision diagnosis and treatment. DNA aptamer‐based logic devices provide a distinct advantage in this context, as they can logically analyze multiple cell surface markers with high efficiency. However, the susceptibility of natural DNA (D‐DNA) to degradation can compromise the sensitivity and specificity of these devices, potentially leading to false‐positive and false‐negative results, particularly in complex biological environments. To address this issue, dual‐ and triple‐aptamer‐based cell‐surface logic devices are designed and developed using mirror‐image L‐DNA, a chiral molecule of D‐DNA with high biostability. These devices allow for simultaneous analysis of multiple cell surface proteins, achieving greater specificity in cell identification and isolation than D‐DNA‐based logic devices. The L‐DNA probes realized 98.7% and 70.5% sensitivities in FBS buffer with dual‐ and triple‐aptamer‐based logic devices for target cell identification, while D‐DNA probes only showed 27.9% and 0.1%. It is believed that the high stability of L‐DNA and the high efficiency of the devices for labeling cell subpopulations will have broad applications in the life sciences, biomedical engineering, and personalized medicine.

Published: October 2024

AbstractDespite the remarkable advances in the field of perovskite photovoltaics, the use of toxic solvents for their fabrication poses a significant challenge to their scale‐up and commercialization. The vast majority of studies rely on using the highly hazardous N, N‐Dimethylformamide (DMF), with green alternatives remaining scarce. In this work, the use of glycerol formal (Gly‐F) is reported as a green solvent for fabricating quasi‐2D (n = 5) perovskite solar cells. Quasi‐2D perovskite films processed from Gly‐F exhibit a high degree of uniformity and a compact microstructure. When integrated into solar cells, the green solvent‐processed films reach a promising power conversion efficiency of 14.53%. This performance is lower than that of DMF‐based perovskites, most likely due to the presence of laterally oriented low n perovskite phases. Interestingly, while the performance of DMF‐based devices is rather irreproducible, the performance of Gly‐F‐based devices is robust and consistent. These results demonstrate the potential of Gly‐F‐ as a promising green alternative to DMF.

AbstractSince the COVID‐19 pandemic and the Russia–Ukraine War, global food markets have been in turmoil. Agricultural input and energy prices doubled between 2020 and 2022, with immediate consequences on food accessibility. We examine the drivers of the EU food inflation patterns, and how trade integration shapes these dynamics. We find that food price inflation has been mainly driven by surges in agricultural production costs and, to a lesser extent, by global food price increases. Trade openness has not exacerbated the inflating dynamics during this period. We conclude with reflections on inflationary, production, and trade policies.

AbstractBackgroundEmergency departments serve as the front line for individuals facing acute health needs, often compounded by social determinants of health (SDoH). Integrating SDoH into emergency medicine care is vital for promptly addressing health concerns and averting future crises. This curriculum adopts a team‐based approach to train emergency medicine residents in identifying and addressing SDoH, thereby delivering comprehensive and equitable care.MethodsThe curriculum employs various educational strategies, including presession readings, SDoH introductions, case simulations, debriefing sessions, panel discussions, and collaboration with other health care professionals. Evaluation via pre‐ and postcurriculum surveys revealed substantial enhancements in residents' comprehension, identification, and familiarity with local resources related to SDoH.ResultsFindings indicated an uptick in residents' grasp and acknowledgment of SDoH, alongside their capacity to address these factors. Posttraining Likert scores exhibited notable improvements across all domains, underscoring an augmented ability to manage SDoH in clinical practice. This curriculum amplifies residents' capability to deliver patient‐centric care and advocate for health equity.ConclusionsContinuous refinement and assessment are paramount for ensuring residents' readiness to navigate the intricate social determinants affecting patients' well‐being. Ultimately, this curriculum heralds a pivotal stride toward fostering health equity and refining patient care standards within emergency medicine.

AbstractObjectiveThis study describes the 2010–2019 trend of cervical cancer (CC) in women over 55 by socio‐demographic index (SDI) and geographical regions.MethodsWe obtained data on CC annually from 2010 to 2019 from the 2019 Global Burden of Disease Study (GBD) to analyze the incidence, death and prevalence rates, and disability‐adjusted life years (DALYs) associated with CC across different parameters such as global trend, age groups, SDI, continents, World Bank Regions, World Health Organization (WHO) regions, GBD regions, and National and territorial division. This analysis covers data from 204 countries and territories from 1990 to 2019.ResultsThere were 236,228 CC incidence cases worldwide in 2019, which is a 1.27‐fold increase from 2010. Global CC deaths also increased to 169,304 cases in 2019, reflecting a 1.24‐fold increase. CC prevalence increased to 769,925 cases in 2019, representing a 1.4‐fold rise. The number of CC DALYs globally increased to 3,835,979 cases in 2019, reflecting a 1.24‐fold increase. Incidence, death, prevalence, and DALY numbers of CC increased across all age groups females in the 65–69 years age group experienced the highest increase. Middle SDI countries had the highest incidence, death, prevalence, and DALY numbers, while low SDI countries showed increasing trends. Asia exhibited the highest incidence, death, prevalence, and DALY numbers of CC. Upper middle‐income countries had the highest incidence, death, prevalence, and DALY numbers, with the highest decreases in these rates except the prevalence rate. The Western Pacific Region showed the highest incidence, death, prevalence, and DALY numbers, with declining rate trends. The Republic of Kiribati showed the highest incidence, death, prevalence, and DALY numbers.ConclusionBased on the study results, it is clear that although the global trend of epidemiological indicators of CC is decreasing, the largest proportion of the decreasing trend is related to developing countries. But in regions of Africa and Asia that have a lower level of development, sometimes these indicators show upward trends, which shows the worsening of the problem in these regions and the need for serious policies and plans to implement comprehensive vaccination, screening, and promotion interventions. People's awareness is necessary in the field of better disease control.

Published: October 2024

ABSTRACTSentiment classification deals with extracting and classifying the text sentiment. Fuzzy Deep Belief Network (DBN) has proved its efficiency in dealing with sentiment analysis and suitability for classifying unlabeled or semi‐labeled data. Previous structures of deep belief networks are mostly made of traditional activation functions such as sigmoid. In this paper, a new activation function, which is referred to as hyperbolic secant function, is proposed. The new activation function not only solves gradient zeroing problem but also increases the accuracy and efficiency. Besides, extreme learning machine (ELM) is proposed as the decision layer to increase the accuracy and improve the generalizability through solving gradient‐based learning problem. The efficiency of the proposed method has been experimented on “IMDB” movie critic dataset, 20‐newspaper dataset and Sentiment Analysis dataset. The results of the proposed method are more accurate and precise as compared with the previous approaches.

Wearable strain sensors have transformed the real‐time monitoring of health conditions and human–machine interactions. However, recently developed wearable strain sensors exhibit several limitations. For example, when a sensor is designed with high sensitivity to detect strain, it struggles to accurately measuring the deformation of low‐stiffness materials like skin. Additionally, finding the optimal balance between sensitivity, durability, hysteresis, and strain range in sensor design is challenging. To address these challenges, a Buckled, Ultrasoft, Crack‐based, Large strain, EpiDermal (BUCKLED) sensor is developed. This sensor integrates the benefits of soft structure engineering with high sensitivity of crack‐based sensing mechanisms to ensure optimal skin deformation measurements. The BUCKLED sensor exhibits significant improvements in compliance (18 500 mm N−1), stretchability (100%), hysteresis (2%), durability (10 000 cycles with 100% strain), and force sensitivity () owing to its buckled shape, confirming its ability to detect subtle movements with enhanced accuracy. The sensor's high compliance allows it to accurately measure low‐stiffness objects, ensuring reliable performance. Furthermore, the sensor's tunability is demonstrating its effectiveness in applications such as respiratory monitoring, facial expression recognition, and silent speech interfaces. Consequently, the proposed sensor is versatile and holds great potential for a wide range of sensing applications.

Published: October 2024

AbstractBeta (β)‐thalassemia and sickle cell disease (SCD) are characterized by a hypercoagulable state, which can significantly influence organ complication and disease severity. While red blood cells (RBCs) and erythroblasts continue to play a central role in the pathogenesis of thrombosis in β‐thalassemia and SCD, additional factors such as free heme, inflammatory vasculopathy, splenectomy, among other factors further contribute to the complexity of thrombotic risk. Thus, understanding the role of the numerous factors driving this hypercoagulable state will enable healthcare practitioners to enhance preventive and treatment strategies and develop novel therapies for the future. We herein describe the pathogenesis of thrombosis in patients with β‐thalassemia and SCD. We also identify common mechanisms underlying the procoagulant profile of hemoglobinopathies translating into thrombotic events. Finally, we review the currently available prevention and clinical management of thrombosis in these patient populations.

ABSTRACTMitochondrial disorders exhibit clinical and genetic diversity. Nearly 400 distinct genes, located in both the mitochondrial and nuclear genomes, harbor pathogenic variants that can produce a broad spectrum of mitochondrial diseases. This work aims to explore the genetic etiology of a cohort of Egyptian pediatric patients who were clinically suspected of having a mitochondrial disorder. A total of 49 patients from 44 unrelated families were studied. Selection criteria included age below 18 years and meeting Morava criteria (a score ≥ 3). The mitochondrial disease criteria (MDC) have been developed to quantify the clinical picture and evaluate the probability of an underlying mitochondrial disorder Exome sequencing, including mitochondrial genome sequencing, was carried out for each participant. Causative variants likely responsible for the phenotypes were identified in 68% of the study population. The mitochondrial subgroup constituted 41% of the studied population with a median age of 4 years. No primary pathogenic variants in mitochondrial DNA were detected. Pathogenic or likely pathogenic variants in eight mitochondrial genes were identified in 78% of the mitochondrial cohort. Additionally, seven novel variants were identified. Nonmitochondrial diagnoses accounted for 27% of the study population. In 32% of cases, disease‐causing variants were not identified. The current study underscores the diverse phenotypic and genetic landscape of mitochondrial disorders among Egyptian patients.

AbstractMetal‐free Buchwald‐Hartwig type photocatalytic approach for N‐substitution of 1,2,4‐triazole at normal temperature was explored for the first‐time using novel imidazolium based Brønsted acid functionalized porphyrin (ImBAFPc). The energy band gap and Hammett acidity were determined by UV‐Vis spectrophotometer. The energy band gap, 1.06 eV supported absorption of radiation in the visible region. The N‐arylation of 1,2,4‐triazole with various Ar−X was achieved in a home‐made photoreactor by heterogeneous, recyclable ImBAFPc photocatalyst under irradiation of 5 W LED with good yields. The protocol tolerated electron donating and attracting Ar−X, including inactivated chlorobenzene, affording the arylated triazole with admirable yields. under ambient photocatalytic conditions.
