Highly Efficient and Selective Synthesis of Renewable Isoprene Over Mo-Fe-O and MgO/Mg(OH)2 Composite Catalysts.

Synthesis of renewable isoprene continues to attract significant interest, yet catalysts still need improvement for industrial applications. We report herein an efficient and novel Prins tandem approach for highly selective production of isoprene from bio-based methanol and isobutene over Mo-Fe-O and MgO/Mg(OH)2 acid-base bifunctional catalysts. Hydration decreases the number of strong basic sites O2- ions and increases OH groups over MgO, thus improving the isoprene selectivity. Basic OH on Mg(OH)2 promotes the Prins condensation of formaldehyde and isobutene, while acidic OH promotes dehydration of isoprenol to isoprene. Suitable contents and proportions of basic and acidic OH groups over Mg(OH)2 increase isoprene selectivity and methanol conversion to 90 and 92 % on the Mo-Fe-O+Mg(OH)2 composite catalysts, respectively. It exhibits good recycling stability, with isoprene selectivity remaining 90 % after five successive regenerations. DFT calculations reveal OH groups formed after hydration reduce the energy barrier of the H transfer step, thereby promoting the overall reaction.

Directly Regenerating of Spent LiCoO2 with Gradient F-Doped Subsurface towards Ultra-Stable Storage Properties.

As great potential recycling strategy, the direct regeneration of spent LiCoO2 (LCO) is beneficial for lowering environmental pollutions and promoting global sustainability. However, owing to the using of binder and electrolyte, some fluorine impurities would be remained into spent materials. Considering the doping behaviors of F-elements, their suitable content introducing would facilitate the energy-storage abilities of regenerated LCO. Herein, through the tailored introduction of F-elements, spent LCO are successfully regenerated with physical-chemical evolutions. Benefitting from the existed oxygen vacancies, the diffusion energy-barrier of F-elements is reduced from 1.73 eV to 0.61 eV, facilitating the establishment of gradient F-doped subsurface, along with the formation of rigid CoO5F. Meanwhile, excess F-elements (1 wt %, as a threshold) lead to the formation of LiF passivation layer on the surface. Thus, the as-optimized sample displays a considerable capacity of 154.4 mAh g-1 even at 5.0 C, with retention rate (88.3 %) in 3.0-4.5 V. Supported by detailed electrochemical and kinetic analysis, the structural advantages are confirmed to boost the improved redox activity of Co-ions and the alleviating of irreversible oxygen-release. Give this, the work is anticipated to reveal the evolutions of regenerated LCO with the introduced F-elements, whilst providing the practical regeneration strategies toward excellent high-voltage properties.

Symmetric Connected U-Net with Multi-Head Self Attention (MHSA) and WGAN for Image Inpainting

This study presents a new image inpainting model based on U-Net and incorporating the Wasserstein Generative Adversarial Network (WGAN). The model uses skip connections to connect every encoder block to the corresponding decoder block, resulting in a strictly symmetrical architecture referred to as Symmetric Connected U-Net (SC-Unet). By combining SC-Unet with a GAN, the study aims to reconstruct images more effectively and seamlessly. The traditional discriminators only differentiate the entire image as true or false. In this study, the discriminator calculated the probability of each pixel belonging to the hole and non-hole regions, which provided the generator with more gradient loss information for image inpainting. Additionally, every block of SC-Unet incorporated a Dilated Convolutional Neural Network (DCNN) to increase the receptive field of the convolutional layers. Our model also integrated Multi-Head Self-Attention (MHSA) into selected blocks to enable it to efficiently search the entire image for suitable content to fill the missing areas. This study adopts the publicly available datasets CelebA-HQ and ImageNet for evaluation. Our proposed algorithm demonstrates a 10% improvement in PSNR and a 2.94% improvement in SSIM compared to existing representative image inpainting methods in the experiment.

Regenerable and stable olefin-linked covalent organic frameworks with coordination template for selective and efficient trapping of scandium ion

Using coordination templates within covalent organic frameworks (COFs) can significantly enhance the selective properties of these materials. Herein, 1,4-phthalaldehyde, 2,4, 6-trimethyl-1,3, 5-triazine, and a scandium coordination complex were selected to perform a three-in-one strategy, and a class of stable olefin-linked covalent organic frameworks with coordination templates were synthesized. By adjusting the proportion of organic ligands to scandium complexes, a range of crystalline COFs with tunable scandium incorporation levels has been obtained. Upon removing scandium from the material with the suitable metal content, we achieved a metal-imprinted COF (De-Sc-0.33), demonstrating remarkable affinity and selectivity for Sc3+ ions, even in acidic environments and amidst competing metal ions (53.56 mg/g). In particular, the skeleton benefits from the characteristics of olefins, and its regenerability and stability in highly acidic environments surpass those of existing scandium adsorbents (with a capacity drop of less than 2 % after 20 cycles), thus holding tremendous potential for the enrichment of scandium in practical applications.

Performance analysis of biodiesel derived from pork fat of swill and concentrate-fed pigs

With the escalating demand for sustainable energy solutions, unconventional sources are gaining attention, including the utilisation of pork fat for biodiesel production. This study investigates the influence of different pig feeding systems, namely swill and concentrate, on the characteristics and performance of biodiesel derived from pork oil. Twelve Large White Yorkshire piglets were divided into two treatments: one following standard feeding practices (T1), and the other exclusively fed with swill (T2). The pigs were slaughtered, and their fat was processed into biodiesel through transesterification. The fuel properties of the biodiesel were analysed, including kinematic viscosity, flash point, fire point, gross calorific value, and low-temperature fuel properties. Additionally, engine performance and exhaust emissions of a biodiesel blend (B20) derived from pork oil were evaluated and compared to commercial diesel fuel using a Kirloskar single-cylinder diesel engine connected to an eddy current dynamometer. Results indicate that both T1 and T2 B20 biodiesel exhibit favourable characteristics comparable to diesel, with promising fuel density, injection duration, mass flow rate, brake-specific fuel consumption, and brake thermal efficiency across various load conditions. Moreover, critical factors such as cetane number and gross calorific value suggest suitable ignition qualities and energy content, highlighting the potential of pork oil-derived biodiesel as a sustainable alternative fuel source. Keywords: Biodiesel, pork fat, swill, concentrate feeding systems

Pickering emulsions stabilized by cellulose nanofibers with tunable surface properties for thermal energy storage

Cellulose nanofibers (CNFs) have been widely used as a renewable emulsifier to stabilize two immiscible liquids due to their intrinsic amphiphilicity and excellent emulsifying ability. However, it remains challenging to fully understand the effects of carboxylate group content and surface charge density on the emulsifying ability of CNFs and the stability of Pickering emulsion. Herein, carboxymethylated CNFs were extracted from bleached kraft pulp using etherification reaction and high-pressure homogenization, allowing for easy surface charge density and size adjustment by changing sodium chloroacetate content and homogenization cycles. The optimizing CNFs possessed a high Zeta potential (−71.2 mV) and a suitable carboxylate group content (1.81 mmol/g), which enabled CNFs to irreversibly adsorb at the hydrophobic paraffin wax (PW) droplet surface and form interfacial steric barriers, providing large electrostatic repulsion between the PW droplets against coalescence. Thus, the CNF-stabilized PW emulsions could be stored for more than 6 months. Moreover, the phase change enthalpy of the freeze-dried emulsion is as high as 193.7 J/g, which provides the emulsion to reversibly store and release heat. This work provides a comprehensive insight into the interfacial stability mechanism of CNFs as stabilizers and facilitates the potential application in thermal energy storage.

Supercapacitive behaviors of N/S co-doped biomass porous carbon-based supercapacitors in “water-in-salt” electrolyte

The design of carbon electrode materials and electrolytes is distinct significance for improving the energy density of supercapacitors. Herein, N/S co-doped biomass porous carbon materials based on sustainable resource were prepared by in-situ expansion, heteroatom doping, and subsequent KOH activation strategy by using camellia seed shell as carbon source and ammonium persulfate as dopant and expander. The as-prepared N/S co-doped biomass porous carbon (N/S-CSAC-650) possesses the characteristics of high specific surface area, large pore volume, and suitable heteroatom content. The N/S-CSAC-650 electrode achieves a high specific capacitance of 335.9 F g−1 in the 3 M KOH electrolyte at 0.5 A g−1. The constructed symmetric supercapacitor demonstrates excellent cyclic stability and shows a high retention rate of 98.4 % after 30,000 charge and discharge processes at 2 A g−1. Especially, the energy density of supercapacitors is usually constrained by the narrow electrochemical stability window (ESW) of dilute aqueous solution (1.23 V), in order to effectively widen the ESW of water, herein the “water-in-salt” (WIS) electrolyte strategy is put forward and the ESW of water was extended to 2.94 V by using a 25 M KAc WIS electrolyte. The operating voltage window of the symmetric supercapacitor assembled by 25 M KAc WIS electrolyte and N/S-CSAC-650 electrodes can reach 2.0 V, and a high energy density of 48.86 Wh kg−1 is realized.

Effects of copper doping on microstructural evolution and oxygen permeability of Ce0.8Sm0.2O2-δ-Sm0.6Sr0.4Fe1-xCuxO3-δ dual-phase oxygen permeable membranes

Ce0.8Sm0.2O2-δ(wt.70 %)-Sm0.6Sr0.4Fe1-xCuxO3-δ(wt.30 %) (SDC-SSFC) dual-phase oxygen permeable membranes were prepared by one-pot EDTA-citric acid combined complexing method. Effects of copper doping content on crystallographic phase, microstructure and oxygen permeability were deeply investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) combined with energy-dispersive X-ray spectroscopy (EDXS). Systematic studies reveal that SDC as oxygen ion conductors and SSFC as electron conductor display an excellent synergistic effect only if a suitable doping content of copper was adopted. It can be found that Ce0.8Sm0.2O2-δ-Sm0.6Sr0.4Fe0.9Cu0.1O3-δ exhibits the highest oxygen permeation flux of up to about 0.61 ml cm−2 at 950 °C and lower oxygen permeation activation energy, which displays nearly a two-fold increase in oxygen permeability compared with the sample without any copper doping. If the copper doping content in B-site of SSFC perovskite exceeds about 30 %, a third phase, i.e., CuO, would appear in the bulk of SDC-SSFC dual-phase membrane and the grain size of CuO tend to gradually increase which would degrade the oxygen permeability of SDC-SSFC dual-phase membrane. Kinetical analysis showed that the critical membrane thickness (Lc) of Ce0.8Sm0.2O2-δ-Sm0.6Sr0.4Fe0.9Cu0.1O3-δ membrane is close to approximately 0.6 mm, i.e., if the membrane thickness is larger than 0.6 mm, its rate-determining step would transform into the bulk-diffusion exchange from surface exchange. Meanwhile, Ce0.8Sm0.2O2-δ-Sm0.6Sr0.4Fe0.9Cu0.1O3-δ membrane exhibits a stable oxygen permeation flux of up to 0.32 ml cm−2·min−1 in pure CO2 atmosphere for more than 120 h without any degradation.

Meta concept recommendation based on knowledge graph

Massive Open Online Courses (MOOCs) are playing a key role in improving educational ways. Abundant learning resources make it difficult for online users to find suitable learning content. The current personalized service in the field of online education relies more on course recommendations. However, coarse-grained recommendations cannot help users discover the defects of their knowledge network effectively. In this paper, we propose a Knowledge-Aware Meta-Concept (KAMC) framework to provide fine-grained recommendation services. We innovatively incorporate Knowledge Graph (KG) into the field of educational recommendation to provide abundant auxiliary information. However, simply combining knowledge graphs with educational recommender systems cannot improve the performance of existing recommendation models, and may even weaken the performance of the models. Because the modeled KG ignores the enhancements on the user side and only considers the enhancements on the item side. We further propose to enrich the semantic representation of users with collaborative information in user-item interactions, and at the same time enrich the semantic representation of items with information in KG. Furthermore, to provide users with more accurate and fine-grained personalized recommendation services, we propose a user-based attention mechanism to capture users’ fine-grained semantic information. Our method is experimentally validated on three real-world datasets. In the three datasets, KAMC’s AUC evaluation index is 6.2%\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$6.2\\%$$\\end{document}, 6.9%\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$6.9\\%$$\\end{document}, and 2.2%\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$2.2\\%$$\\end{document} higher than the latest baseline method (KGAN), respectively.

Reliability and validity assessment of instrument to measure sustainability practices at shipping ports in India

Sustainability has emerged as one of the most critical factors influencing the competitiveness of maritime shipping ports. This emergence has led to a surge in research publications on port sustainability-related topics. However, despite the increasing awareness and adoption of sustainability practices, documented literature on empirical studies with survey and interview data is very limited. Moreover, the existence of validated instruments to objectively assess sustainability through sustainability practices for shipping ports in India needs to be traced. This study contributes by validating an instrument to evaluate objectively sustainability practices in shipping ports by adopting a four-stage process, starting with item identification based on an extensive literature review, instrument evaluation by subject matter experts, assessing of the instrument with suitable content validation indices, and finally evaluating the validity and reliability of the hypothesized theoretical model. For content validation, Content Validity Index, Cohens Kappa coefficient, and Lawshe’s Content Validity Ratio were computed with the assessment by a subject matter expert panel comprising six members from the port industry as well as academicians cum researchers in the field of shipping ports. The content-validated instrument was administered to 200 samples comprising officer category port employees. The measurement model was evaluated and validated using the Confirmatory Factor Analysis to assess the extent to which the measured variables represent the theoretical construct of the study and ascertain the factor structure. The empirically validated instrument met the required guidelines of model fit, reliability, and construct validity measures and was found to be a confirmed model for measuring sustainability practices in shipping ports. Structural Equation Modeling methodology was adopted to explain the variance and the path relationship between the higher-order and lower-order constructs of sustainability. The results indicate that the economic dimensions are the major contributors to the overall sustainability of the port as they drive investments in environmental and social dimensions, leading to overall sustainable development. The study’s findings will be helpful for researchers, academicians, policymakers, and industry practitioners working towards sustainability practices that contribute to sustainable growth and development in the shipping industry.

Rapid fabrication of Ni supported MgO-ZrO2 catalysts via solution combustion synthesis for steam reforming of methane for hydrogen production

In this study, we introduced a solution combustion as a simple, efficient, and rapid technique for synthesis of a nanostructured Ni catalyst supported on MgO-ZrO2 for hydrogen production by steam reforming of methane. A series of Ni/MgO-ZrO2 catalysts with different Ni contents were prepared and investigated to observe a suitable Ni loading content. The evaluation of catalytic performance of the as-prepared catalysts was performed in a packed-bed reactor at 700 °C and atmospheric pressure at steam to carbon ratio (S/C) of 2. As a result, the 20Ni/20MgO-ZrO2 catalyst exhibited not only outstanding catalytic performances, but also minimized coke deposits, attributed to the presence of oxygen vacancies of MgO-ZrO2 solid solution. In addition, combustion synthesis could result in formation of NiO-MgO solid solution, boosting uniform dispersion of Ni particles. A durability test of the optimized 20Ni/20MgO-ZrO2 catalyst was conducted at 700 °C for 50 h, revealing a near constant methane conversion of approximately 92.9%. Although filamentous carbon and carbon encapsulation were observed on the surface of spent catalyst, there is no significant negative impact on the steam reforming performance. In conclusion, this present work highlights the efficacy of the solution combustion method for synthesis of nanostructured Ni/MgO-ZrO2 catalysts with superior catalytic performance and less coke deposits for hydrogen production from methane steam reforming.

Improvement of gummy candy structure by gelling ingredients and cooling temperature

AbstractGummy candies achieve their widespread appeal through a unique textural profile. The combination of springiness, chewiness, and a potential initial hardness upon biting (depending on formulation) creates a multi‐sensory eating experience. The readily soluble sugars and other components contribute to the quick dissolution and ease of digestion. Therefore, we conducted research to develop gummy candies made from structural materials of gelatin combined with agar and maltose syrup and evaluated the effect of ingredient ratios on the candy's structural and sensory properties. Sweetener maltose syrup (DE = 42) and a suitable content of agar supplementary had a significant influence on the structure of the product (p < 0.05). The structure of gummy candies was analyzed by the structure measuring instrument TPA (structure profile analysis) combined with sensory evaluation. The process of manufacturing candy involves the melting and homogenization of all constituent ingredients, followed by a sequence of freezing and cool drying to complete the production. The most interesting candies were made with agar 0.5%, gelatin 10% (powdered gelatin with Bloom 250), saccharose 30%, maltose syrup 10%, citric acid 0.1%, and pure water before being chilled at 4 °C for 4 h. This property remained unchanged during the 6‐month storage period in anaerobically sealed packaging, at room temperature.

Enhancing Self-Regulated Learning through Flipped Classroom and Gamification in Applied Computer for Business Courses

This study examined the impact of a flipped classroom with gamification on students' self-regulated learning (SRL) among students in the Applied Computer for Business course. Research questions addressed: (1) How does this approach affect students' SRL? (2) What are students' perceptions of this method? A mixed-methods approach was employed, using pre- and post-implementation questionnaires, open-ended questions, and interviews. Results indicated a significant increase in SRL across all dimensions, with the mean SRL score improving significantly (p < 0.05). The content analysis results showed that 85% of students were satisfied with the instruction, and 78% believed the approach enhanced their learning management skills. The findings suggested that the success of the flipped classroom with gamification depends on providing adaptation support, ensuring internet access, selecting suitable content and activities, and addressing individual differences. Instructors are advised to offer clear explanations, precise gamification planning, and utilize online platforms for real-time updates to enhance the effectiveness of this approach.
