Abstract Membrane gas absorption and solar-assisted absorbent regeneration offer a sustainable approach to reduce the energy penalty of post-combustion CO₂ capture. This study introduces a novel system integrating solar thermal energy with membrane gas absorption to capture CO₂ from a 580 MWe pulverized coal power plant. The environmental impacts across six scenarios at varying solar fractions are evaluated via life cycle assessment. Results show a 7.61%–13.04% reduction in global warming potential compared to a steam-driven CO₂ capture system. Electricity and steam consumption dominate the operational phase, contributing 15%–64% and 18%–61% to environmental impacts in non-TES scenarios, respectively. While More >

Abstract Heavy metal contamination in water sources is a widespread global concern, particularly in developing nations, with various treatment approaches under extensive scientific investigation. In the present study, we fabricated electrospun composite polyvinylidene fluoride (PVDF) nanofibrous membranes exhibiting hierarchical surface roughness and superhydrophobicity for the removal of heavy metal ions via vacuum membrane distillation (VMD) process. The membranes were prepared by incorporating optimized dosing of silica nanoparticles, followed by a two-step membrane modification approach. These membranes exhibited notable characteristics, including elevated water contact angle (152.8 ± 3.2°), increased liquid entry pressure (127 ± 6 kPa), and… More > Graphic Abstract

Abstract Anion exchange membrane (AEM) fuel cells require membranes with a balance of high conductivity and durability. In this work, a novel bi-crown-ether modified piperidine structure was designed and synthesized, which was then introduced into the side chain of poly(arylene piperidinium), making a unique bi-crown-ether modified bi-piperidinium side chain grafted polymer for AEM fabrication. The double crown ether units enhanced cation–water interactions and promoted microphase separation, thereby forming efficient hydroxide ion transport channels. The resulting membrane exhibited high water uptake, well-defined ion clusters, and a hydroxide conductivity of 123 mS cm⁻¹ at 80°C with an ion exchange More >

Abstract A new quadrilateral finite element IQ4 is developed for the free vibration of carbon nanotube-reinforced composite (CNTRC) perforated plates with a central cutout. By enriching the membrane part and incorporating a projected shear technique, the IQ4 element is proposed to address the known limitations of the standard Q4 element, such as shear locking and limited consistency in the coupling of membrane-bending components. The proposed element is formulated within the FSDT-based framework and assessed through benchmark tests to verify its convergence and accuracy. The governing equations are obtained via the weak form of Hamilton’s principle. Particular… More >

Abstract Background: To investigate the impact of preoperative extracorporeal membrane oxygenation (ECMO) on clinical outcomes in pediatric heart transplantation (PHT). Methods: This retrospective cohort analysis was conducted on 19 pediatric heart transplant recipients, divided into two groups: ECMO and non-ECMO, based on whether preoperative ECMO was utilized. We evaluated the patients’ surgical conditions, postoperative complications, and survival rates. Additionally, the analysis focused on the differences and correlations in clinical characteristics, inflammatory markers, and long-term survival outcomes. Results: There was no statistically significant difference in perioperative survival rates between the ECMO group (85.7%) and the non-ECMO group (83.3%). However,… More >

Abstract The structural integrity monitoring of high-density polyethylene (HDPE) geomembranes in landfill containment systems presents a critical engineering challenge due to the material’s vulnerability to mechanical degradation and the complex vibration propagation characteristics in large-scale installations. This study proposes a dual-stream deep learning framework that synergistically integrates raw vibration signal analysis with physics-guided feature extraction to achieve precise rupture detection and localization. The methodology employs a hierarchical neural architecture comprising two parallel branches: a 1D convolutional network processing raw accelerometer signals to capture multi-scale temporal patterns, and a physics-informed branch extracting material-specific resonance features through continuous More >

Abstract Background: Intermediate-risk prostate cancer (IR-PC) represents a heterogeneous group requiring nuanced treatment approaches, and recent advancements in radiotherapy (RT), androgen deprivation therapy (ADT), and prostate-specific membrane antigen positron emission tomography (PSMA-PET/CT) imaging have prompted growing interest in personalized, risk-adapted management strategies. This study by the Turkish Society for Radiation Oncology aims to examine radiation oncologists’ practices in managing IR-PC, focusing on RT and imaging modalities to identify trends for personalized treatments. Methods: A cross-sectional survey was conducted among Turkish radiation oncologists treating at least 50 prostate cancer (PC) cases annually. The 22-item questionnaire covered IR-PC… More >

Abstract In the realm of all-electric aircraft research, the integration of cathode-open proton exchange membrane fuel cells (PEMFC) with lithium batteries as a hybrid power source for small to medium-sized unmanned aerial vehicles (UAVs) has garnered significant attention. The PEMFC, serving as the primary energy supply, markedly extends the UAV’s operational endurance. However, due to payload limitations and spatial constraints in the airframe layout of UAVs, the stack requires customized adaptation. Moreover, the implementation of auxiliary systems to facilitate cold starts of the PEMFC under low-temperature conditions is not feasible. Relying solely on thermal insulation measures… More >

Abstract Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is a life support intervention for patients with refractory cardiogenic shock or severe cardiopulmonary failure. However, the choice of cannulation strategy remains contentious, partly due to insufficient understanding of hemodynamic characteristics associated with the site of arterial cannulation. In this study, a geometrical multiscale model was built to offer a mathematical tool for addressing the issue. The outflow cannula of ECMO was inserted into the ascending aorta in the case of central cannulation, whereas it was inserted into the right subclavian artery (RSA) or the left iliac artery (LIA) in… More >

Abstract The flow field architecture of the proton exchange membrane fuel cell (PEMFC) cathode critically determines its performance. To enhance PEMFC operation through structural optimization, trapezoidal obstacles were implemented in the cathode flow channels. The height dependence of these obstacles was systematically investigated, revealing that a 0.7 mm obstacle height enhanced mass transfer from channels to the gas diffusion layer (GDL) compared to conventional triple-serpentine designs. This configuration achieved a 12.08% increase in limiting current density alongside improved water management. Subsequent studies on obstacle distribution density identified 75% density as optimal, delivering maximum net power density More >
