Preparation and sensing performance of chiral carbon Dot@MOF electrode material
Authors: Wu Liping , Duan Qian 
Published: June 2024

Abstract
Chirality is a ubiquitous phenomenon in nature. The identification of chiral compounds has important theoretical significance and application prospects in many fields such as biology, medicine, and food. This paper proposes an innovative approach to differentiate enantiomers by using the synergistic effect of chiral MOFs and CDs through electrochemiluminescence. The results demonstrate that CDs@[Zn(D-cam)(phen)(H2O)]n exhibit higher electrochemiluminescent response towards L/D-Trp, enabling the detection of Trp enantiomers. This research suggests that selective recognition of amino acid enantiomers can be achieved through ECL-based nanocomposites of CDs and porous MOFs.

Published: June 2024

Abstract
N, N-dimethylformamide (DMF) is used as a drying inhibitor to prepare ZrO2 aerogels. The properties were investigated and the result reflected that adding DMF can get bulk aerogels with better mechanical strength (0.51 MPa), lower density (0.38 g/cm3), lower thermal conductivity (0.024 W·m-1·K-1), and higher specific surface area (123.46 m2/g) after heat treatment. Its performance as a drying inhibitor is better than that of formamide (FA). It indicates that DMF can be used as a drying inhibitor to prepare zirconia aerogel with excellent thermal stability and mechanical strength.

Authors: Wang Xuanye , Zhuo Wenhan , Cui Yueyue , Hu Manfang 
Published: June 2024

Abstract
Hydrogels are water-rich network polymers. The hydrophilic groups on the polymer molecular chains ensure their swelling property and high water content, and the cross-linked hydrogel network and the intermolecular interactions between the polymer molecular chains generate cohesive forces to prevent further penetration of water molecules. The porous structure of the gel enables water molecules to freely traverse the polymer network and the high-frequency flow of molecules in water offers a viable method for the preparation of hydrogel electrolytes. As a result, hydrogel electrolytes are now an important conductive material to compensate for the defects of conventional electronic materials, such as hardness and roughness, and lack of environmental friendliness. This paper starts with the method of hydrogel electrolyte preparation. Good stretchability, conductivity, biocompatibility, and self-healing properties are demonstrated by introducing different materials such as conductive nanomaterials. The types of synthetic conductive hydrogel matrices are extended according to the type of composite materials, making the hydrogel electrolytes usable in many fields like sensing, electrochemical energy storage, biomedicine, environmental detection, flexible wearable fields, and other applications.

Study on the properties of slump-retaining polycarboxylate superplasticizer synthesized by EPEG at different pH
Authors: Lin Zhiqun 
Published: June 2024

Abstract
The application of EPEG-type polycarboxylate water reducer in concrete is gradually widespread and studying its preparation process and performance comparison will help promote the EPEG market. In this study, ethylene glycol nonvinyl polyoxymethylene ether (EPEG-2400), acrylic acid (AA) and hydroxyethyl acrylate (HEA) were used as the main synthetic monomers. Under the redox initiation system of hydrogen peroxide-formaldehyde sodium bisulfite, EPEG-type water-retaining polycarboxylate water reducer was synthesized by free radical copolymerization in aqueous solution. The influence of different pH values on the dispersibility of the synthesized polycarboxylate water reducer was studied. The results show that different pH values have little influence on the molecular weight of EPEG water-retaining polycarboxylate water reducer and the work performance of EPEG-synthesized water-retaining polycarboxylate water reducer is better under neutral conditions.

Abstract
With styrene (St), butyl acrylate (BA), and methyl methacrylate (MMA) as monomers, a core-shell structure was utilized to synthesize a polymerization emulsion. Then, self-crosslinked polyacrylic acid emulsions with different crosslinking degrees were synthesized by changing the amount of DAAM using deception acrylamide (DAAM) and adipic acid dihydrazide (ADH) as functional monomers. The basic performance tests demonstrated that the inclusion of DAAM resulted in an increase in the emulsion’s stability and film’s solvent resistance; The DSC test demonstrated that boosting the crosslinking degree was advantageous in improving the T
g of the film; according to FT-IR and microscopic tests, the crosslinking reaction took place in the system. The self-crosslinking acrylic emulsion of this system has a certain application prospect as a binder.

Authors: Xu Hetong , Wang Jianhua , Hui Xin , Zhang Runan 
Published: June 2024

Abstract
The superparamagnetic Fe3O4 was fabricated by the solvothermal synthesis, in which medium ferric chloride is the iron source and deoxidizer using as ethylene glycol. The core-shell material Fe3O4@SiO2 was fabricated by the scheme which was composed of Anhydrous ethanol, deionized water, ammonia water, and tetraethyl orthosilicate (TEOS). The structural and optical characteristics of the samples Fe3O4 and core-shell Fe3O4@SiO2 was detected by X-ray diffraction (XRD), transmission electron microscope (TEM), Vibrating sample magnetometer (VSM), and UV/VIS/IR spectrophotometer. The conclusions illustrate that the spherical core-shell structure of Fe3O4 and Fe3O4@SiO2 were fabricated with superparamagnetic. The Ostwald ripening effect on structure of sample Fe3O4 was concluded to form inverse spinel polycrystal structure by nanometer particles. The visual-driven photocatalytic properties of Fe3O4 and Fe3O4@SiO2 nanoparticles toward the deposition of methodology blue was studied. The obtained conclusions indicate that Fe3O4@SiO2 after irradiated by visible light, its degradation rate of methodology methylene mlue (MB) was enhanced than Fe3O4 in the presence of H2O2. The samples Fe3O4 and core-shell Fe3O4@SiO2 materials are recycled by external magnetic field and reused for special superparamagnetic property. The sample Fe3O4 and core-shell Fe3O4@SiO2 materials represent higher catalytic property and excellent fixity consistent with the decomposition rate of methodology methylene mlue (MB) after being recycling and reuse severe times. The photocatalytic mechanism was dismissed based on the determined active agent during the process of degraded wastewater.

Abstract
The present report prepared three novel chiral phosphine-functionalized polyetherimidazolium ionic liquids through ion-exchange reactions of chiral sulfonated BINAP ligands and hydroxyl-functionalized polyetherimidazolium ionic liquids grounded on the phosphine ligand-ionic liquid integration. Using these synthetics, methyl acetoacetate was subjected to asymmetric homogeneous hydrogenation catalyzed by ruthenium. The structural characterization of the three chiral phosphine-functionalized polyetherimidazolium ionic liquids was conducted using 1H NMR, 13C NMR, and 31P NMR in combination with HR-MS. Compared with their precursor sulfonated BINAP, the prepared chiral phosphine-functionalized ionic liquids exhibited comparable or better catalytic activity and enantioselectivity.

Published: June 2024

Abstract
Pitting corrosion is harmful and often occurs in chloride solution. The pitting corrosion of 4Cr13 steel in a chlorine tank was investigated in this study. Cr-depleted rings were observed and the Cr-depleted ring coincided with the bumps consisting of corrosion product. Carbides distributed along the Cr-depleted ring were also observed. Many pitting with spherical or shallow shapes were observed by cross-section morphology exam. The depth of pitting for Sample A is smaller than that for Sample B which accorded with surface morphology. The corrosion product was composed of a Fe-rich outer layer and a Cr-rich inner layer. The Fe-rich outer layer will rapture and fall off with the increase of corrosion products, and then the Cr-rich inner layer was revealed. As a result, Cr-depleted rings were inspected with SEM-EDS. The pitting corrosion mechanism of 4Cr13 steel in the chlorine tank was also discussed.

Published: June 2024

Abstract
For this study, bisphenol A epoxy resin (DGEBA) was used as the resin matrix, and 3,3’-diaminodiphenyl sulfone (33DDS) was used as the curing agent. The effects of different cross-linking densities on the mechanical properties of epoxy resins were studied by molecular dynamics (MD) simulation, and the changes in the mechanical properties of epoxy resins under five different cross-linking density levels were predicted [1]. The results showed that as the cross-linking density of the epoxy resin increased, the mechanical parameters (such as elastic modulus, shear modulus, and bulk modulus) of the epoxy resin system also increased. This indicates the importance of improving the curing process of epoxy resin to enhance its mechanical properties.

Authors: Zhang Bingyu , Zhang Xue , Wen Xianxin , Qin Dui 
Published: June 2024

Abstract
Hypoxia and acidity are key characteristics of the tumor microenvironment (TME). Gelatin methacryloyl (GelMA) is a versatile biomaterial extensively utilized in various biomedical fields. Studies have shown that during the photocrosslinking process of GelMA hydrogel, the commonly used photoinitiator Irgacure 2959 consumes oxygen and induces an acidic and hypoxia environment. However, there is currently limited research on its involvement in the three-dimensional (3D) culture of tumor cells. Therefore, we constructed a 3D culture system utilizing GelMA hydrogel and investigated its influence on the growth and drug response of lung cancer cells (A549). The results demonstrated that the GelMA hydrogel-based 3D culture system exhibited excellent biocompatibility and robust mechanical properties and provided an acidic microenvironment conducive to tumor cell proliferation. Furthermore, the cancer cells exhibited heightened sensitivity to chemotherapeutics in this 3D culture model. These results suggest that the GelMA hydrogel-based 3D culture system can serve as a perfect model for in vitro study of tumor cells.
The penetrating restoration mechanism of reactive polymer on slight crack of asphalt pavement
Authors: Wang Jie , Yuan Bo , Yang Bo , Dang Jing , Tang Shutong , Li Yuanyuan , Chen Yaohui 
Published: June 2024

Abstract
To explore the penetrating restoration mechanism of reactive polymer on slight crack (<3 mm) of asphalt pavement, based on the self-developed reactive MMA material, through the combination of viscosity control and micro-analysis methods, the penetration depth of different viscosities of binding materials to micro-crack and microstructure of the preventive maintenance interface were studied. The results show that the penetration depth of the binding material to the micro-crack is positively correlated with the viscosity of the material, and the restoration effect of the micro-crack depends on the fullness of the filling and curing state of the material in the crack. When the filler content is 20%, the penetration depth of the binding material to the micro-crack can reach 1 mm. The penetration depth can be changed through viscosity control, and a full-continuous restoration structure can be obtained. The microstructure of the micro-crack restoration area shows that the penetration enhancement of the polymer seal material to the micro-crack in the pavement includes three processes: penetration, filling, and curing.
Molecular dynamics study on self-assembled dodecylphosphocholine nanomicelles used as drug delivery system for carrying curcumin
Authors: Shu Qijiang , Bi Jun , Lu Jingjing 
Published: June 2024

Abstract
Curcumin has rich and diverse medicinal effects. Incorporating curcumin into suitable nanocarriers can inhibit its unfavorable biological characteristics and improve its utilization rate. In this work, we combine quantum chemistry and molecular simulation techniques to investigate the mechanism of action of dodecylphosphocholine (DPC) molecules encapsulating curcumin. The results show that van der Waals forces act as the main actuating force to load the drug. Hydrogen bonding and electrostatic forces also contribute to the clustering of DPC molecules. A typical spacing at which intermolecular interactions occur is mainly around 0.52 nm. All quantitative data and visualization images of the system conformation together show that the DPC molecules self-assemble to form multiple micelles and present a good morphology for loading curcumin. This demonstrates the potential of DPC to act as a novel vehicle for delivering curcumin.
Effect of particle/matrix interface parameters on mechanical properties of high-energy propellant based on three-dimensional RVE model
Authors: Zhao Jiuling 
Published: June 2024

Abstract
For composite solid propellant, the interface is the medium to transfer the load between particles and matrix. Because there are a large number of particle/matrix interface layers in the propellant, the mechanical properties of the interface become an important factor affecting the macro-mechanical properties of the propellant. It is necessary to study the influence of different interface mechanical parameters on the mechanical properties of high-energy propellants. In this paper, the three-dimensional representative volume element (RVE) model of solid propellant is established, and the three-dimensional bilinear cohesion interface parameters are established for this model. The influence law of interface parameters on its mechanical properties is obtained through simulation research. The results show that both the interfacial strength and the maximum failure displacement of the interface affect the tensile strength of high-energy propellant, and the interfacial strength plays a leading role and is very significant.

Authors: Tsougkas Konstantinos 
Published: June 2024

Abstract
The spectral zeta function of the Laplacian on self-similar fractal sets has been previously studied and shown to meromorphically extend to the complex plane. In this work we establish that under certain conditions a relationship exists between the logarithm of the determinant of the discrete graph Laplacian on the sequence of graphs approximating the fractal and the regularized Laplacian determinant on the fractal itself which is defined via help of the spectral zeta function. We then at the end present some concrete examples of this phenomenon.

Published: June 2024

Abstract
Indonesia, as the largest nutmeg producer in the world, must continue to improve its performance, both upstream and downstream, in order to continue to increase its competitiveness. The nutmeg essential oil refining agro-industry in Indonesia, one of the downstream industries, generally still uses a production process which can be said to have not experienced any real changes from the past, including using a distillation process for a long time, the resulting yield is not optimal, and is still unable to re-utilize liquid waste in the form of hydrosols left over from the separation of essential oils produced. Efforts that are thought to be able to overcome this problem are by implementing a circular economy approach that can accommodate economic and social activities to overcome problems in the nutmeg essential oil refining agro-industry, including through a circular material input model (circular inputs) and product life extension (product use). The purposes of this paper was to study the conceptual agro-industry of nutmeg essential oil refining in a comprehensive manner based on a review of the latest related scientific papers, such as papers downloaded from Science direct, Emerald insight, Google scholar, Garuda portal, Cross-reef as well as DOAJ.

Abstract
The food and beverage industry in Indonesia has the greatest overall consumption value of halal products across all industries, according to a research published by the Halal Market 2020/2021. The public becomes more aware of a product’s halal status as a result of this case, and they also demand further information about it. Thus, to guarantee a product’s transparency, halal traceability is required. Halal traceability refers to the process of tracking a product’s halal status. This study was carried out at PT Sreeya Sewu, a chicken slaughterhouse business that has integrated halal blockchain technology for halal traceability. The purpose of this study is to develop supply chain KPIs that take traceability into account. 12 Key Performance Indicators/KPIs will be chosen and verified once KPIs are created using the SCOR methodology. AHP pairwise comparisons will be used to weight the verified KPIs. According to the findings, KPI-02 has the most weight. KPI-10 Cycle time for item trace has the lowest weight at 0.076 and the highest percentage at 0.533 for halal training.

Published: June 2024

Abstract
The agropolitan city of Batu is ready to boost the number of Micro, Small, and Medium Enterprises (MSMEs) each year through its flagship product, potato chips. Throughout the supply chain, potato chips can change from halal to non-halal due to contamination by non-halal materials, production processes that do not comply with halal criteria (SJPH), and no separation of halal and non-halal products during storage and distribution. This research aims to illustrate institutional risks in the halal supply chain for the potato chip MSME cluster using the SCOR method. SSOP and GMP are added to strengthen the analysis. Key actors in the halal supply chain institution include suppliers, manufacturers, and retailers. The study identifies several risky activities that threaten the halal integrity of potato chip products. Using the SCOR method for risk mapping in the halal supply chain institution resulted in 69 risk events and 70 risk agents. The potential risks in the halal supply chain for potato chips occur mainly at the manufacturer level (70% of the total risk events). They are most prevalent in the production process variable. The majority of risk agents in micro-scale businesses are related to the implementation of PPH, SJPH, SSOP, and food safety.

Authors: Wangintan Roy , Yani Moh. , Hardjomidjojo Hartrisari , June Tania 
Published: June 2024

Abstract
The rapid activity in Jakarta due to high economic growth increases air pollution, which impacts health problems and environmental, social, and ecological disturbances. The research objectives are to determine factors for controlling air pollution, score and evaluate the matrix of direct influence (MDI), draw a direct and indirect influence graph, and make rating and classification comparisons. The information collection was carried out by applying the Center Gather Dialog strategy to decide the factors that impact contamination control. Information evaluation was carried out utilizing the interpretive structural modelling (ISM) with matrice d’ impacts cruises multiplication appliqué a classement (cross-impact matrix multiplication applied to classification, abbreviated as MICMAC). The results show that the factor that influences air pollution control is high concentrations resulting from activities in the transportation sector and industrial sector. Economic growth has an indirect effect because economic growth is correlated in the same direction as air pollution. The transportation sector consists of motorized vehicle activities such as cars, two-wheeled motorbikes, aeroplanes, trains, and ships that use oil fuel, which contributes to the high concentration of air pollution in Jakarta. Controlling air pollution must involve all parties, including government responsibility, public awareness, transportation, and industrial actors. All parties should implement and comply with regulations effectively and efficiently. Air pollution monitoring activities must be carried out appropriately and regularly.
