Here, we study glycine-functionalized hydrotalcite (eHT–gly) as a novel filler to enhance transport and static antifouling tendency of polyamide-based membranes. TFN membranes were prepared by coating a delaminated eHT–gly aqueous dispersion (0.005–0.25 wt%) onto the substrate prior to sequential MPD/TMC interfacial polymerization. The SEM-EDX data revealed a loading-dependent shift in the degree of polyamide layer crosslinking, based on a semi-quantitative O/N indicator. The disappearance of the XRD basal spacing, together with TEM imaging showing thin, electron-translucent nanosheet domains, indicates successful exfoliation. The film hydrophilicity (with a water contact angle of 43.6°) and the presence of a hydration layer facilitated by zwitterionic species of glycine gave better filtration results. The membrane containing 0.125wt% eHT–gly produced 95% NaCl rejection at 111.7 LMH (at 0.2 MPa), higher than the native eHT membrane with NaCl rejection of 88.6% and flux of 87.7 LMH, respectively. The eHT–gly-modified membranes loaded with ≥0.05 wt% showed reduced static BSA adsorption, indicating a preliminary antifouling tendency. The eHT–gly is a potential nanofiller for surface modification of TFN membranes for low-pressure nanofiltration to produce freshwater from brine water.</div></div>","PeriodicalId":100614,"journal":{"name":"Hybrid Advances","volume":"14 ","pages":"Article 100740"},"PeriodicalIF":0.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148940184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The adsorption of NH₃, CO, and NO₂ molecules is analyzed to evaluate their effects on graphene's electronic structure, charge transport, and sensor response. The simulations are carried out using the non-equilibrium Green's function (NEGF) formalism under a symmetric step voltage bias. The results demonstrate that gas adsorption modifies the carrier concentration and density of states by altering the graphene band structure, leading to significant variations in electrical conductivity and drain current.

The main reasons for this are latency limitations, changes in sensor data, and the lack of effective temporal modeling in existing approaches. Traditional methods such as CNN, LSTM, and Transformer based architectures face problems such as high computational complexity, delayed inference, or limited compatibility on edge devices. To overcome these limitations, in this research we proposed SwiftGaitNet, a low-latency Edge-AI framework that is specifically designed for real-time prosthetic gait phase detection. The proposed system consists of Force Sensitive Resistor (FSR) signals, Inertial Measurement Unit (IMU) data collected by an IoT based wearable sensing setup and foot pressure information coordinated by multimodal sensor fusion. Lightweight temporal attention, gated temporal convolution, adaptive residual fusion and efficient fully connected decision layers are used in this architecture, so that faster sequential learning is possible with less computational load. Compared to existing methods, the proposed model is specially optimized for edge inference, thus providing fast and reliable real-time predictions without the need for heavy processing. According to the results of the experimental evaluation, SwiftGaitNet demonstrated better performance than the traditional baseline models CNN, LSTM, Transformer and CNN-LSTM. This model achieved 97.6% accuracy, 97.6% precision, 97.6% recall, and 97.6% F1-score, evaluated using a subject-independent, 5-fold Leave-One-Subject-Out (LOSO) cross-validation protocol on a dataset of 2250 temporal windows collected from 50 walking trials across four gait-phase classes (Heel-Strike, Mid-Stance, Toe-Off, and Swing). Inference latency, averaging 12.1 ± 1.8 ms, was measured directly on the deployed ESP32 DevKit hardware using TensorFlow Lite Micro rather than estimated offline. The proposed framework demonstrates computational efficiency while maintaining accurate real-time gait-phase detection. These results suggest that SwiftGaitNet is a promising candidate for low-latency, edge-deployed gait phase detection in wearable and prosthetic sensing systems; however, further work involving closed-loop prosthetic-control integration and validation with prosthetic users is needed before its suitability for clinical or real-time prosthetic-assist deployment can be established.</div></div>","PeriodicalId":100614,"journal":{"name":"Hybrid Advances","volume":"14 ","pages":"Article 100734"},"PeriodicalIF":0.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148940634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the effectiveness of embedded co-cured Selective Area Reinforcement (SAR) using Kevlar in improving the residual tensile behaviour of unidirectional (UD) GFRP laminates containing 2 mm, 4 mm, and 6 mm circular design-sensitive regions. Open-hole tensile tests were conducted to evaluate ultimate tensile strength, normalized residual strength, hole sensitivity, reinforcement efficiency, and strength retention behaviour. In addition, finite element analysis (FEA) was performed to examine stress redistribution around the design-sensitive region and validate the experimental observations. The experimental results demonstrated progressive degradation in residual tensile strength with increasing discontinuity severity due to intensified stress concentration and localized damage accumulation. However, the embedded SAR significantly improved residual tensile performance, strength retention, and damage tolerance under all investigated conditions. A modified residual strength criterion and a Stress Redistribution Efficiency Index (SREI) were developed to characterize SAR-assisted stress redistribution behaviour. The finite element results showed excellent agreement with the experimental data and confirmed that the embedded SAR effectively reduced localized stress concentration by promoting more uniform load transfer around the design-sensitive region. Failure morphology further revealed crack arrest, fibre bridging, fibre pull-out, and reduced edge splitting, indicating enhanced residual structural integrity and delayed damage propagation.

This study investigates the three-dimensional flow and heat-transfer behavior of a Casson quaternary hybrid nanofluid composed of Cu, ZrO₂, Al₂O₃, and Fe₃O₄ nanoparticles dispersed in ethylene glycol. The analysis considers steady, incompressible, laminar boundary-layer flow over a stretching surface in the presence of a Riga plate, Darcy–Forchheimer porous medium, magnetic field, velocity slip, thermal radiation, convective boundary condition, and temperature-dependent viscosity and thermal conductivity. Appropriate similarity transformations are employed to convert the governing partial differential equations into a system of nonlinear ordinary differential equations. The transformed equations are solved numerically using the Galerkin Weighted Residual Method implemented in Mathematica 11.3. The results show that the magnetic field, porous-medium resistance, slip parameter, and variable viscosity reduce the velocity field, whereas Riga-plate forcing accelerates the near-wall flow. Thermal radiation, Biot number, and variable thermal conductivity significantly influence the thermal boundary layer and heat-transfer behavior. Under the investigated conditions, the quaternary hybrid nanofluid exhibits comparatively enhanced heat-transfer characteristics relative to the corresponding dual- and tri-hybrid nanofluids.

Despite its potential, the technology faces challenges including particle agglomeration, scalability, and production costs. Long-term environmental concerns, such as toxicity and bioaccumulation, must also be addressed.
