AbstractPerovskite solar cells are increasingly acknowledged for their unique characteristics. This study focuses on simulating the impact of methylammonium lead bromide‐based perovskites, as the absorber in perovskite solar cells using the SCAPS‐1D simulator. The research delves into how the performance of these solar cells is affected by the choice of Electron Transport Layers (TiO2, PCBM, SnO2, and ZnO) and Hole Transport Layer (Cu2O) with Ni and Al as the back and front contact. This investigation marks the first comprehensive exploration of CH3NH3PbBr3. The performance of these device architectures is significantly influenced by factors such as defect density, absorber thickness, ETL thickness, and the combination of different ETLs. The power conversion efficiencies of devices optimized with TiO2, PCBM, SnO2, and ZnO are found to be 15.46%, 15.33%, 15.01%, and 14.99%, respectively. Furthermore, this study elucidates the impact of absorber and HTL thickness. Also, they have discussed the VBO, CBO for different ETLs. Additionally, the effects of series resistance, shunt resistance are examined, operating temperature, quantum efficiency (QE), capacitance‐voltage characteristics, generation and recombination rates, current density‐voltage (J‐V), and impedance analysis of the devices. Through this extensive simulation study, researchers are equipped to develop cost‐effective and highly efficient PSCs, thereby advancing solar technology.

AbstractThe synergistic effect of ferroelectric and HfO2/SiO2 (Hafnium dioxide/ Silicon dioxide) hetero dielectrics in double gate Junctionless Field Effect Transistor is investigated using TCAD Tool. The study encompasses a wide range of parameters, allowing for a detailed examination of the impact of hysteresis on the overall functionality of the double gate Junctionless FET. One crucial aspect of the investigation involves examining the analog and RF performance of the device. The high transconductance (gm) of 5.42 mS, a gain of 95 dB (decibel), a cut‐off frequency of 553.9 GHz (gigahertz), a gain transconductance frequency product (GTFP) of 50.9 THz (terahertz), and a gain bandwidth product (GBW) of 188 GHz shows its great potential for analog and RF signal processing applications as well as for other high data rate wireless applications such as Machine Learning (ML), Artificial Intelligence (AI) and Internet‐of‐Thing (IoT). The low transit time of 17 ns (nano second), with high ION/IOFF ratio range of 107 shows that the device has good switching behavior also. This aspect of the research aims to unveil the device's viability for analog and high‐frequency applications, contributing valuable insights to the emerging electronic technologies field.

Published: June 2024

AbstractNonsense‐mediated decay (NMD) and autophagy play pivotal roles in restricting virus infection in plants. However, the interconnection between these two pathways in viral infections has not been explored. Here, it is shown that overexpression of NbSMG7 and NbUPF3 attenuates cucumber green mottle mosaic virus (CGMMV) infection by recognizing the viral internal termination codon and vice versa. NbSMG7 is subjected to autophagic degradation, which is executed by its interaction with one of the autophagy‐related proteins, NbATG8i. Mutation of the ATG8 interacting motif (AIM) in NbSMG7 (SMG7mAIM1) abolishes the interaction and comprises its autophagic degradation. Silencing of NbSMG7 and NbATG8i, or NbUPF3 and NbATG8i, compared to silencing each gene individually, leads to more virus accumulations, but overexpression of NbSMG7 and NbATG8i fails to achieve more potent virus inhibition. When CGMMV is co‐inoculated with NbSMG7mAIM1 or with NbUPF3, compared to co‐inoculating with NbSMG7 in NbATG8i transgene plants, the inoculated plants exhibit milder viral phenotypes. These findings reveal that NMD‐mediated virus inhibition is impaired by the autophagic degradation of SMG7 in a negative feedback loop, and a novel regulatory interplay between NMD and autophagy is uncovered, providing insights that are valuable in optimizing strategies to harness NMD and autophagy for combating viral infections.

Authors: Wang Huimin , Yan Zhenhua , Cheng Fangyi , Chen Jun 
Published: June 2024

AbstractRenewable energy‐driven proton exchange membrane water electrolyzer (PEMWE) attracts widespread attention as a zero‐emission and sustainable technology. Oxygen evolution reaction (OER) catalysts with sluggish OER kinetics and rapid deactivation are major obstacles to the widespread commercialization of PEMWE. To date, although various advanced electrocatalysts have been reported to enhance acidic OER performance, Ru/Ir‐based nanomaterials remain the most promising catalysts for PEMWE applications. Therefore, there is an urgent need to develop efficient, stable, and cost‐effective Ru/Ir catalysts. Since the structure‐performance relationship is one of the most important tools for studying the reaction mechanism and constructing the optimal catalytic system. In this review, the recent research progress from the construction of unsaturated sites to gain a deeper understanding of the reaction and deactivation mechanism of catalysts is summarized. First, a general understanding of OER reaction mechanism, catalyst dissolution mechanism, and active site structure is provided. Then, advances in the design and synthesis of advanced acidic OER catalysts are reviewed in terms of the classification of unsaturated active site design, i.e., alloy, core‐shell, single‐atom, and framework structures. Finally, challenges and perspectives are presented for the future development of OER catalysts and renewable energy technologies for hydrogen production.

AbstractPrecise control of quantum structures in hybrid nanocrystals requires advancements in scientific methodologies. Here, on the design of tunable CsPbBr3/Cs4PbBr6 quantum dots are reported by developing a unique discrete phase transformation approach in Cs4PbBr6 nanocrystals. Unlike conventional hybrid systems that emit solely in the green region, this current strategy produces adjustable luminescence in the blue (450 nm), cyan (480 nm), and green (510 nm) regions with high photoluminescence quantum yields up to 45%, 60%, and 85%, respectively. Concentration‐dependent studies reveal that phase transformation mechanisms and the factors that drive CsBr removal occur at lower dilutions while the dissolution–recrystallization process dominates at higher dilutions. When the polymer‐CsPbBr3/Cs4PbBr6 integrated into a field‐effected transistor the resulting phototransistors featured enhanced photosensitivity exceeding 105, being the highest reported for an n‐type phototransistor, while maintaining good transistor performances as compared to devices consisting of polymer‐CsPbBr3 NCs.

Published: June 2024

AbstractLight‐based 3D printing techniques represent powerful tools, enabling the precise fabrication of intricate objects with high resolution and control. An innovative addition to this set of printing techniques is Optical Fiber‐Assisted Printing (OFAP) introduced in this article. OFAP is a platform utilizing an LED‐coupled optical fiber (LOF) that selectively crosslinks photopolymer resins. It allows change of parameters like light intensity and LOF velocity during fabrication, facilitating the creation of structures with progressive features and multi‐material constructs layer‐by‐layer. An optimized formulation based on allyl‐modified gelatin (gelAGE) with food dyes as photoabsorbers is introduced. Additionally, a novel gelatin‐based biomaterial, alkyne‐modified gelatin (gelGPE), featuring alkyne moieties, demonstrates near‐visible light absorption thus fitting OFAP needs, paving the way for multifunctional hydrogels through thiol‐yne click chemistry. Besides 2D patterning, OFAP is transferred to embedded 3D printing within a resin bath demonstrating the proof‐of‐concept as a novel printing technology with potential applications in tissue engineering and biomimetic scaffold fabrication, offering rapid and precise freeform printing capabilities.

AbstractThe liver requires careful handling intra‐operatively owing to its vital functions and complexity. Traditional open hepatectomy, while standard, is invasive and requires long recovery periods. Laparoscopic hepatectomy is a less invasive option, with its own challenges. The rise of robotic surgery, such as the da Vinci® system, improves precision and control, addressing the limitations of conventional methods, but brings new concerns, such as costs and training. This review focuses on the latest advancements in robotic hepatectomy from 2022/23 articles, delving into topics like “robotic surgery in liver transplantation,” “robotic hepatectomy for hilar cholangiocarcinoma,” “robotic vascular reconstruction following hepatectomy,” “robotic repeat hepatectomy,” and “prospective trials in robotic hepatectomy.” To retrieve articles, a focused literature search was conducted using PubMed for articles from 2022/23 with a 5‐year filter, excluding reviews. Initially, abstracts were screened, and relevant articles on robotic surgery were examined in full for inclusion in this review. Although all the above items are cutting‐edge, and many of the references are necessarily at the level of case reports, recent articles are still accompanied by surgical videos, which are useful to readers, especially surgeons who are considering imitating the procedures. In summary, we examined the recent advancements in robotic liver resection. The inclusion of videos that present new techniques aids in knowledge transfer. We anticipate the continued growth of this field of research.

AbstractAimWe previously reported that abdominal aortic calcification is associated with poor overall and recurrence‐free survival after hepatectomy for hepatocellular carcinoma (HCC). However, the effect of abdominal aortic calcification on cancer‐specific prognosis in very old patients with several comorbidities remains unknown. This multicenter study aimed to evaluate the impact of abdominal aortic calcification on the cumulative recurrence rate and recurrence‐free survival in patients with HCC aged >80 years.MethodsWe retrospectively analyzed the data of 128 patients (aged ≥80 years) who underwent liver resection for hepatocellular carcinoma at seven hospitals belonging to Hiroshima Surgical Study Group of Clinical Oncology between January 2014 and December 2018. Patients were divided into two groups: high and low abdominal aortic calcification groups. The primary endpoints were cumulative recurrence rate and recurrence‐free survival.ResultsKaplan–Meier survival curve analysis demonstrated that the cumulative recurrence rate in the high abdominal aortic calcification group was significantly higher than that in the low abdominal aortic calcification group, and the high abdominal aortic calcification group had a significantly lower recurrence‐free survival rate. In the multivariate analysis, high abdominal aortic calcification (p = 0.03), high des‐gamma‐carboxyprothrombin score (p = 0.04), and multiple tumors (p < 0.01) were independent predictive factors for recurrent HCC, and high abdominal aortic calcification (p = 0.01) and high des‐gamma‐carboxyprothrombin (p = 0.01) were independent predictive factors for poor cancer‐specific survival.ConclusionsOur results indicate that the abdominal aortic calcification score is associated with cumulative recurrence rate and recurrence‐free survival in very old patients with HCC.
Sleep correlates of behavior functioning in Cornelia de Lange syndrome
Authors: Ng Rowena , Grados Marco , O'Connor Julia , Summa Deirdre , Kline Antonie D. 
Published: June 2024

AbstractPathogenic variants in the cohesin genes, NIPBL and SMC1A, both cause Cornelia de Lange syndrome (CdLS), a rare genetic disorder associated with developmental delay and intellectual disability. This study aimed to compare sleep behaviors across individuals with CdLS caused by a variant in NIPBL or SMC1A, and identify relationships between sleep and behavior functioning. A total of 31 caregivers of individuals with a variant in NIPBL (N = 22) or SMC1A (N = 9) completed questionnaires regarding their child's sleep behaviors, behavior regulation, attention, and autistic features (repetitive behaviors and social communication difficulties) as part of the Coordination of Rare Diseases (CoRDS) registry. Findings showed a trend of increased behavior regulation difficulties and repetitive behaviors in the NIPBL compared to the SMC1A participants. Both groups presented with a similar degree of attention, social communication, and sleep challenges. In the whole sample, sleep disturbance was strongly correlated with more behavior regulation difficulties, a relationship that was more robust in the NIPBL sample. In brief, study results support our prior observations of greater behavior difficulties among those with a variant in NIPBL as compared to SMC1A. Preliminary findings point to unique associations between sleep and behavior regulation in the NIPBL group, suggesting sleep interventions may yield differential effects on behavior management across variants.

AbstractINTRODUCTIONBumetanide, a loop diuretic, was identified as a candidate drug for repurposing for Alzheimer's disease (AD) based on its effects on transcriptomic apolipoprotein E signatures. Cross‐sectional analyses of electronic health records suggest that bumetanide is associated with decreased prevalence of AD; however, temporality between bumetanide exposure and AD development has not been established.METHODSWe evaluated Medicare claims data using Cox proportional hazards regression to evaluate the association between time‐dependent use of bumetanide and time to first AD diagnosis while controlling for patient characteristics. Multiple sensitivity analyses were conducted to test the robustness of the findings.RESULTSWe sampled 833,561 Medicare beneficiaries, 60.8% female, with mean (standard deviation) age of 70.4 (12). Bumetanide use was not significantly associated with AD risk (hazard ratio 1.05; 95% confidence interval, 0.99–1.10).DISCUSSIONUsing a nationwide dataset and a retrospective cohort study design, we were not able to identify a time‐dependent effect of bumetanide lowering AD risk.Highlights

AbstractThis study investigates the dynamics of quantum coherence and entanglement in the spin‐1 Heisenberg XXZ model. Particularly, the effects of the Heitler‐London (HL) coupling and the Dzyaloshinskii‐Moriya (DM) interaction are examined. By utilizing tools from quantum information theory, the concept of quantum correlated coherence and negativity are explored. The results show intrinsic decoherence leads to a decay of both correlated coherence and negativity. Interestingly, it is found that a small value of the Dzyaloshinskii‐Moriya interaction can significantly enhance coherence and entanglement. Various factors influence the system dynamics, including the initial state, anisotropy parameter, and the coupling distance between spins. It is shown that, by fixing the anisotropy parameter, the isotropic Heisenberg models XX and XXX can be easily recovered. Ultimately, the findings highlight that the system maintains a coherent temporal evolution despite decoherence.

AbstractCarbon‐based materials have been utilized as effective catalysts for hydrogen peroxide electrosynthesis via two‐electron oxygen reduction reaction (2e ORR), however the insufficient selectivity and productivity still hindered the further industrial applications. In this work, we report the Fe−O4 motif activated graphitic carbon material which enabled highly selective H2O2 electrosynthesis operating at high current density with excellent anti‐poisoning property. In the bulk production test, the concentration of H2O2 cumulated to 8.6 % in 24 h and the corresponding production rate of 33.5 mol gcat−1 h−1 outperformed all previously reported materials. Theoretical model backed by in situ characterization verified α‐C surrounding the Fe−O4 motif as the actual reaction site in terms of thermodynamics and kinetics aspects. The strategy of activating carbon reaction site by metal center via oxo‐bridge provides inspiring insights for the rational design of carbon materials for heterogeneous catalysis.
Parenting children with Down syndrome: A systemic look at the disability experience
Authors: Jeter Kaitlin , Hardin Michael P. 
Published: June 2024

AbstractThe birth of a child with a disability is often experienced as traumatic and life altering to the members of the family. Current marriage and family therapy programs and curricula require very little, if any, clinical training or supervision related to disabilities, and this prompts many therapists in the field to consider therapy with families experiencing disability to be outside their scope of practice. As a part of its nature, Down syndrome (DS) is a spectrum disorder with varying levels of health and general functioning from individual to individual, which change over the course of the lifespan. Parents of children with disabilities often experience greater levels of stress and are at higher risk for developing relational/psychological distress than parents of neurotypical children. Unique parental stressors include ambiguous loss, balancing multiple parental roles, increased demand for resources, and discrimination stress. This study interviewed married couples to observe the unique experience of parenting a child with DS and the diagnosis' effects on the individual parent, as well as marriage and family dynamics. From the gained narrative observations, clinical implications are presented to assist therapists in appropriate treatment of couples and families navigating life with DS.
Interactive experimental study on microgroove structure and drag‐reducing additives in rotating disk apparatus

Published: June 2024

AbstractA series of interactive experiments are conducted to analyze the drag reduction technology with a rotating disk apparatus that combines microgroove structure and drag‐reducing additives including polyethylene oxide (PEO), cetyltrimethyl ammonium chloride (CTAC), and sodium salicylate (NaSal). By varying the disk type, concentration of drag‐reducing additives, temperature, and Reynolds number (Re), the corresponding drag reduction rates are obtained effectively. The experimental results indicate that adding CTAC strengthens the heat degradation and shear resistance of PEO; while PEO can enhance the ability of CTAC to form micellar structures and balance energy distribution at low concentrations. Moreover, the synergistic effect of these two additives presents a better drag reduction performance with a maximum drag reduction rate of 24.1%; while the microgroove structure enhances the effect of active drag reduction. Therefore, the combination of active and passive drag reduction technology broadens the application of energy saving and consumption reduction in hydraulic rotating machinery.

Published: June 2024

AbstractUncontrollable bleeding caused by accidental severe trauma and organ operation severely affects people's life safety, even leading to death. Therefore, it is important to cease the bleeding quickly and effectively. Here, we report a rapid photocrosslinking hydrogel (DP‐F127 hydrogel) based on F127 and acrylate functional motifs for in situ emergency hemostasis. The acrylate groups in DP‐F127 can be cross‐linked within 10 s by UV irradiation. The resulted hydrogels exhibit excellent mechanical properties, biocompatibility, and rapid hemostatic ability. The in vivo studies on the DP‐F127 hydrogel demonstrated that liver bleeding could be rapidly repaired and show significantly less blood loss than commercially available dressing (Gelatin sponge, GS). This study provides a new paradigm for developing a hemostatic hydrogel with the rapid speed of crosslinking for in situ emergency hemostasis.
