This study constructed dHA algae oil emulsions using sodium caseinate (NaCS) as an emulsifier and by controlling the mass fraction of glycerol in the aqueous phase (0-90 wt%). The differences of physicochemical properties, oxidative stability, and bioaccessibility were systematically investigated. The findings indicated that the incorporation of glycerol significantly enhanced the emulsion performance. The emulsion with high glycerol content (90 wt%) exhibited the smallest droplet size (185.6 ± 4.05 nm), the highest apparent viscosity and shear modulus, demonstrating weak gel characteristics, and maintained excellent stability within the pH range of 3-8 and under centrifugal conditions. By inhibiting the dissolved oxygen in the aqueous phase and delaying oxygen diffusion, the glycerol emulsion significantly slowed down the oxidation process of dHA algae oil, with lower primary oxidation products (POV) and secondary oxidation products (TBArS) compared to the conventional emulsion (0 wt% glycerol). Additionally, it inhibited the oxidation of tryptophan and the formation of Schiff bases in NaCS, effectively suppressing protein oxidation. In vitro simulated digestion experiments showed that the dHA bioaccessibility of all emulsions was above 85%, which was three times higher than that of pure algae oil (27.8%), and the glycerol content had no significant effect on it. This study confirms that the low-water glycerol-NaCS emulsion system can synergistically enhance the oxidative stability and bioavailability of dHA algae oil, providing a new strategy for developing long-lasting and stable functional lipid delivery systems.

The characteristics of bulk-forming of refractory metal were analyzed, and the effects of strain paths and microstructures on the Mo bulk-forming were discussed. By means of finite element method, metallographic and Electron Backscattered diffraction (EBSd), the flow and strain distribution of the Mo bulk after multi-direction forging were analyzed. It was found that the metal flow in the core of bulk was intense, and the strain storage energy was the largest. The grain sizes in the core were also larger than those around edges, and there were still some deformed textures in the material. The metallographic results were similar to the Finite Element Method (FEM) results. © 2019, Springer Nature Singapore Pte ltd.

The current study had conducted the life cycle analysis (LCA) to assess the environmental impact of microalgal wastewater treatment via an integrated membrane bioreactor. The functional unit selected for this analysis was 1 kg of treated microalgal wastewater with contaminants eliminated by ultrafiltration membrane fabricated from recycled polyethylene terephthalate waste. Meanwhile, the applied system boundary in this study was distinguished based on two scenarios, namely, cradle-to-gate encompassed wastewater treatment only and cradle-to-cradle which included the reutilization of treated wastewater to cultivate microalgae again. The environmental impacts and hotspots associated with the different stages of the wastewater treatment process had clearly elucidated that membrane treatment had ensued the highest impact, followed by microalgal harvesting, and finally cultivation. Among the environmental impact categories, water-related impact was found to be prominent in the following series: freshwater ecotoxicity, freshwater eutrophication and marine ecotoxicity. Notably, the key performance indicator of all environmental impact, i.e., the global warming potential was found to be very much lower at 2.94 × 10−4 kg co2 eq as opposed to other literatures reported on the LCA of wastewater treatments using membranes. Overall, this study had proffered insights into the environmental impact of microalgal wastewater treatment and its stimulus for sustainable wastewater management. The findings of this study can be instrumental in making informed decision for optimizing microalgal wastewater treatment and reutilization assisted by membrane technology with an ultimate goal of enhancing sustainability. © 2024 Elsevier Inc.

In this paper, we present a method to robustly estimate normal of unorganised point clouds, namely Iterative Weighted Principal component Analysis (IWPCA). Since the neighbourhood of a point in a smooth region can be well approximated by a plane, the classical Principal component Analysis (PCA) is a widely used approach for normal estimation. Iterations are applied and bilateral spatial normal weights are introduced in each iteration for the local plane fitting to enhance the reliability of the PCA results. Minimal Spanning Tree (MST) is used to reorient flipped normals. We demonstrate the effectiveness and robustness of the proposed method on a variety of examples. © 2020 Inderscience Enterprises ltd.

With the rapid development of 5 G technology and microelectronics, there is an urgent demand to design and develop modified polyimide films with low dielectric constant as flexible matrix materials. In this work, a diamine containing multiple side methyl and biphenyl groups was synthesized by aromatic nucleophilicsubstitution reaction and oxidation-reduction reaction, respectively. Furthermore, this monomer was used to polymerize with four different commercially available dianhydrides (OdPA, BTdA, BPdA, and PMdA) to produce a class of polyimides (PI 3a∼3d). The structures of the diamine and its PIs are characterized, and the relationship between the structure and properties of the obtained PI films is investigated. These modified PIs are easy to cast into films and have low dielectric constants and water absorption. Their dielectric constants and dielectric losses are in the range of 2.66–2.91 and 0.00579–0.00677 at 1 MHz, respectively. Meanwhile, these PIs also maintains good thermal stability, with glass transition temperatures (Tg) higher than 284 °C and 10% weight loss temperatures in the range of 496–505 °C at *** abstractdisplay full size

In order to study the effect of asphalt aging of open-graded friction course (OGFC) on the performance of high-viscosity styrene-butadiene-styrene(SBS) modified asphalt during the mixing of the asphalt mixtures and the whole life cycle, Thin Film Oven Test (TFOT), rolling Thin Film Oven Test (rTFOT), and Pressurized Aging Vessel Accelerated Asphalt Aging Test (PAV) were used to conduct aging tests on the high-viscosity SBS modified asphalt. And then the aging of SBS modified asphalt is studied at two levels: microscopic and macroscopic. In the microscopic aspect, first use the fluorescence microscope technology to image the asphalt samples before and after aging. The above images were processed by MATLAB and Image-pro plus software, and the micro-structures of high viscosity SBS modified asphalt before and after aging were obtained. At the same time, use the dSr test to observe the changes in the rheological properties of the SBS modified asphalt before and after aging. On the macro level, the softening point, viscous toughness and pull strength are used to analyse the changes in the mechanical properties of the high-viscosity SBS modified asphalt before and after aging, and the aging conditions of the SBS modified asphalt under the micro and macro indexes are compared. The research shows that after short-term aging (simulation of asphalt aging during the mixing ), rTFOT and TFOT the loss ratio of SBS in modified asphalt are at 78.5% and 68.3%, respectively, the degradation of SBS in modified asphalt is serious, and the SBS modified asphalt aging conditions under the macro and micro indicators are consistent. After long-term aging (simulating the aging of the asphalt during the whole life cycle), the loss ratio of SBS in modified asphalt is 83.4% (rTFOT + PAV) and 84.6% (TFOT + PAV). However, the macroscopic index of SBS modified asphalt shows obvious differences. The aging degree of SBS modified asphalt using rTFOT + PAV aging method is significantly higher than th

Ultra-long flexible wind turbine blades are essential for advancing large-scale and offshore wind energy projects. despite significant progress, optimizing these blades remains a complex challenge due to the need to balance multiple performance objectives simultaneously. In this study, we developed a multi-objective optimization approach for wind turbine blade design that quantitatively addresses power, load, and stall characteristics. To validate the methodology, it was applied to the design of a 2MW wind turbine blade, and the optimized design was compared with a base blade. Sensitivity analysis of the optimization weight parameters was also conducted to enhance the robustness of the approach. The results indicate notable improvements in key performance metrics, including a 1.7% increase in average power generation, a 2.1% reduction in the maximum flap-wise moment at the blade root, and a 1.5°decrease in the running angle of attack. Moreover, the critical tip speed ratio (TSr) decreased by 0.6, aligning with the stall angle and indicating enhanced stall performance. This study not only demonstrates the effectiveness of the multi-objective coupling optimization method but also introduces innovative techniques for stall risk assessment and optimal TSr control, thereby contributing to the advancement of wind turbine blade design.

In this study, a prospective strategy on seed-mediated growth in vacuum is provided and used to prepare flexible silver nanofilms (AC0–3 NFs) with high purity, crystallinity and SErS performance. Noteworthy, AC2 NFs surface is uniformly covered with silver nanoparticles (Ag NPs), following the appearance of numerous nano-gaps between Ag NPs. Through the finite-difference time-domain (FdTd) simulation, it is found that the ultra-small nano-gaps less than 5 nm can generate abundant "hot spots" to amplify the raman signal. Therefore, the above AC2 NFs as SErS substrates exhibit superior activity for the SErS detection of thiram in tomato juice, with the limit of detection (LOd) of 10−15 M and the enhancement factor (EF) of 3.7 × 1011. Meanwhile, AC2 NFs show outstanding reproducibility and stability during the SErS detection. Additionally, the calibration curve is established, by which the thiram (10−7 to 10−15 M) can be quantitatively detected. Clearly, the as-prepared flexible AC2 NFs have great potential in the SErS detection and analysis. © 2025 Elsevier B.V.
