AbstractHygrophila ringens var. ringens is a medicinal plant of the Acanthaceae family. A soluble polysaccharide is extracted from H. ringens seeds using warm water, followed by deproteinization and purification using column chromatography. DL1 is characterized comprehensively using spectroscopic and chromatographic techniques and identified as a polymer containing xylose (Xyl; 78.5%) and 4‐O‐methyl‐d‐glucuronic acid (4‐O‐MeGlcA; 21.5 %). The most prominent glycosidic linkages detected are terminal‐xylose (T‐Xyl); 1,2,3,4‐Xylp; 1,2,4‐Xylp; and T‐4‐O‐MeGlcA. DL1 belongs to the xylan group and is a 4‐O‐methylglucuronoxylan. DL1 exhibits inhibition of bovine serum albumin denaturation with IC50 values of 0.35 mg mL−1 and a similar activity to diclofenac (non‐steroidal anti‐inflammatory drug). In a model of lipopolysaccharide‐stimulated macrophages, DL1 (20–40 µg mL−1) strongly inhibits inflammatory cytokines and reactive oxygen species release without having significant macrophage cytotoxicity. The inhibitory effect of DL1 on inflammatory cytokines is mediated by the activation of mitogen‐activated protein kinases by inhibiting the phosphorylation of p38 and extracellular signal‐regulated kinase. These results highlight the potential of DL1 for treating inflammation through its cytokine‐suppressive activity.
“A Contribution Shared Is a Contribution Halved”: The Influence of Tie Strength‐Based Disclosure Strategy on Potential Donors' Donation Amounts
Authors: Zhao Jing , Pang Wenya 
Published: January 2025

ABSTRACTDonation‐based crowdfunding platforms have increasingly applied disclosure strategies to encourage potential donors to contribute. However, most existing research has not studied the efficacy of showing donors' information by considering the tie strength between the disclosed donors and potential donors. This research was intended to investigate the interactive effects of disclosing donors' information and the tie strength between disclosed and potential donors on potential donors' donation amounts, employing the conceptual frameworks of the we‐mode and I‐mode. Through three online between‐subject experiments (Ntotal = 801), we found that when there was a strong tie between disclosed and potential donors, the disclosure of donors' information led to a decrease in potential donors' donation amounts. The propensity to co‐represent contribution (i.e., the extent to which potential donors take into account the contributions from disclosed donors along with their own as a joint contribution to a donation‐based crowdfunding project) drove the process. Moreover, we also confirmed the boundary condition of recipient type. When the recipient was a group (vs. individual), the negative effect of the propensity to co‐represent contribution on the donation amount was reversed, resulting in the disclosure of donation information from strong‐tie contacts boosting the donation amounts of potential donors. The results challenged the intuition that disclosing social information always increased individuals' donation amounts and complemented the empirical evidence of the negative impact of social information disclosure.

AbstractAntimicrobial resistance poses a growing threat to public health globally. Multidrug resistant Pseudomonas (P.) aeruginosa is detected in many infected wounds and is very challenging to treat with antibiotics. An alternative to antibiotics is to use bacteriophages, highly specific viruses able to kill even resistant bacteria. This work incorporates anti‐P. aeruginosa Neko phages into monoaxial and coaxial electrospun fibers to explore their potential for treating infected wounds. Phages are blended with polyvinyl alcohol (PVA) solution and either processed directly into fibers or used as the core in coaxial electrospinning with polyvinylpyrrolidone (PVP) and PVP/ethyl cellulose (EC) shell solutions. Coaxial fibers stored at −20 °C show promising stability results, with negligible phage titer loss after 6 months of storage. Phage release can be controlled by varying the shell composition. Coaxial fibers with PVP as the shell (PVA/Su PVP + phage) demonstrate immediate release while fibers with PVP/EC as the shell (PVA/Su PVP/EC + phage) display extended‐release. The antibacterial efficacy of phage lysate and phage‐loaded fibers is studied by isothermal calorimetry and found to be unaffected by electrospinning. Thus, it appears that phage‐loaded electrospun fibers merit further investigation as potential wound dressing materials.
Investigations of Microstructures and Properties of SPEEK‐[BMIm][OTf] Ionic Liquid Composite Membrane for Fuel Cells
Authors: Yu Shute , Qin Lanlan , Miao Zhaohong , Zhou Jian 
Published: January 2025

AbstractUtilizing ionic liquids in proton exchange membranes can greatly enhance the performance of fuel cells, enabling their application in high‐temperature and dry conditions. Further advancements in this field depend on a fundamental comprehension of their structural characteristics. This study focuses on the sulfonated poly(ether ether ketone) (SPEEK)‐1‐butyl‐3‐methylimidazolium trifluoromethanesulfonate [BMIm][OTf] composite membrane system. Effects of sulfonation degree, ionic liquid content, and temperature on the structure and conductivity of the composite membrane are investigated by dissipative particle dynamics (DPD) and molecular dynamics (MD) simulations. Results show that [BMIm][OTf] is predominantly distributed around the sulfonic acid groups of SPEEK. At an optimal sulfonation degree and ionic liquid content, interconnected ionic liquid channels can be formed. Nevertheless, an excessively high sulfonation degree may jeopardize the stability of the membrane structure. Moreover, the aggregation of ionic liquid occurs at a high level of ionic liquid content, which hinders the efficient transfer of protons. Generally, increasing the temperature is more conducive to the formation of monodisperse ionic liquid channels within the SPEEK‐[BMIm][OTf] composite membrane; however, overhigh temperature may compromise the integrity of the composite membrane structure. The findings of this study offer molecular insights for the development of high‐temperature proton exchange membrane fuel cell systems.
The Impact of Subsidies on Pricing Decisions in the Battery Swapping Supply Chain Under the “Vehicle and Battery Separation” Model
Authors: Li Chao , Yuan Kai Fu 
Published: January 2025

ABSTRACTTo explore the impact of various subsidies on the battery swapping industry under the “vehicle and battery separation” model, a supply chain comprising a battery manufacturer, a vehicle company, and a battery leasing company is constructed. Based on the no‐subsidy model, decision‐making models are developed for four scenarios that involve subsidizing different entities, including the customer, the battery manufacturer, the battery leasing company, and the vehicle company. Comparative analysis is then conducted. Results show that (1) subsidies do not invariably result in companies lowering prices for their products and services. Under various subsidy strategies, companies tend to adjust their pricing strategies for products and services according to the battery leasing time and the price sensitivity coefficient of battery swapping service. (2) Government subsidies to supply chain entities may not always effectively incentivize more companies to enter the battery swapping industry. Although direct subsidy to vehicle companies could encourage their participation, promoting the involvement of battery manufacturers and leasing companies through direct subsidies may have limited effectiveness. This limitation arises because the optimal profit among various strategies is influenced by factors such as the price sensitivity coefficient of battery swapping service and the battery swapping operating cost sharing ratio. (3) To advance the demand for battery‐swapping vehicles, enhance consumer surplus, and maximize social welfare, the government may prioritize subsidizing vehicle companies. However, when aiming to boost the demand for battery swapping service, the government should consider the level of price sensitivity coefficient of battery swapping service. Specifically, when the price sensitivity coefficient of battery swapping service is low, continuing to subsidize vehicle companies may be advisable. Conversely, when the price sensitivity coefficient is high, it may be more effective to provide subsidies to consumers or battery manufacturers.

Published: January 2025

ABSTRACTThis paper presents the design and fabrication of a 4×4 array antenna based on multi‐mode horn elements and sequential feeding network. The multi‐mode horn antenna is a structure that can suppress grating lobes and side lobe levels by excitation and combining different modes of electromagnetic wave radiation. The sequential feeding network is a technique that can generate circularly polarized radiation from linearly polarized elements by arranging them in a square array with 90° rotations and feeding them with 90° phase difference. The proposed array antenna achieves wideband impedance matching and axial ratio performance, as well as high gain and low complexity. The array antenna operates from 9.9 to 12.6 GHz, with a maximum gain of 24.5 dBi at 11 GHz. The array antenna is fabricated using CNC milling and measured in an anechoic chamber. The measured results agree well with the simulated ones, validating the effectiveness of the proposed design.

Published: January 2025

ABSTRACTThe proposed article offered a closely packed circularly polarized MIMO antenna system for a 5G NR n48/n78 communication system. The design consists of an E‐shaped antenna with modified arms along with shorting pins, and the edge‐to‐edge distance between the radiator is 0.2 mm. The proposed design offers isolation from 15 dB(minimum) to 47.35 dB(maximum) in the range of 3.3 to 3.9 GHz with a peak gain of 4.2 dBi. The uniqueness of this design here is the surface current cancellation technique within the design space of this E‐shaped antenna, which decouples the radiators with high compaction and reduces complexities. To verify the design, the diversity parameters, efficiency, radiation pattern, in‐hand performance, and SAR (specific absorption rate) are calculated, and the results are in good agreement with the measured results. From the above analysis, we can conclude that the proposed closely packed circularly polarized MIMO design can be a good candidate for 5G mobile communication.
Heterogeneous adhesive bonding between different CFRPs and Al 7075 after different surface treatments: A study on the selective practical applicability of the resin pre‐coating (RPC) technique
Authors: Kundu Joydeep , Sethi Abhijeet , Mandal Santosh , Saha Partha 
Published: January 2025

AbstractThis study suggested the judicious application of the resin pre‐coating (RPC) technique during adhesive bonding. Electrochemical surface treatment (ECST) and ultrasonic chemical treatment (UCT) were done on the Al 7075 alloy. Subsequently heterogeneous adhesive bonding of the ECST‐processed and the UCT‐processed alloy with three different CFRPs, namely unidirectional (UD) CFRP, 4‐Harness Satin‐weaved (4HSW) CFRP, and plain‐weaved (PW) CFRP was investigated. ECST and UCT processes resulted in trench‐type surface structures and cavitation pits, respectively. After ECST, contact angles of deionized water and diiodomethane reduced drastically. The highest strengths for the adhesive joints with UD, 4HSW, and PW CFRPs were 28.50, 30.40, and 26.85 MPa, achieved respectively after 10 V ECST without RPC, 1 M UCT without RPC and 1 M UCT with RPC technique. Thin layer cohesive failure at the alloy interface (TLCF‐AI) respectively increased and decreased after application of the RPC technique on the ECST‐processed and the UCT‐processed alloy surface. RPC technique after ECST decreased the single lap shear strengths, whereas this after UCT increased the single lap shear strengths of the heterogeneous adhesive joints with all considered CFRPs. The effectiveness of the RPC technique depended on the combinations of adherend surface morphologies and adhesive properties.Highlights
Judicious application of RPC technique during adhesive bonding was suggested.
ECST or UCT was done on Al 7075 before joining with UD, 4HSW, and PW CFRP.
ECST and UCT respectively caused trench‐type structures and cavitation pits.
RPC after ECST decreased adhesive joint strength and increased TLCF‐AI.
RPC after UCT increased adhesive joint strength and decreased TLCF‐AI.

ABSTRACTIntroductionWenyujin Rhizoma Concisum, named as Pian Jianghuang (PJH) in China, is the decoction piece from the dried rhizome of Curcuma wenyujin Y. H. Chenet C. Ling, has been used to relieve pain for many years in China. However, the qualities of PJH in different districts differ greatly due to their growing environments, which would affect their clinical applications.ObjectiveTo evaluate the qualities of PJH from different districts in China.MethodsHPLC, Heracles NEO ultrafast gas‐phase electronic nose, and Fourier transform near‐infrared (FT‐NIR) spectroscopy were applied to estimate the qualities of PJH from different districts in China.ResultsBy HPLC, the average contents of neocurdione, curdione, germacrone, and furanodiene were 0.203%, 0.151%, 0.022%, and 0.022% in Fujian (FJ); 0.447%, 0.786%, 0.298%, and 0.276% in Zhejiang (ZJ); 0.082%, 0.259%, 0.038%, and 0.019% in Yunnan (YN); 0.041%, 0.022%, 0.260%, and 0.024% in Guangxi (GX); and 0.026%, 0.091%, 0.260%, and 0.016% in Anhui (AH), respectively. By Heracles NEO ultrafast gas‐phase electronic nose, the unique odor components in PJH from FJ, YN, and GX were 1,2,4‐thiadiazole,5‐ethoxy‐3‐(trichloromethyl), 5,6,7,8‐tetrahydroquinoxaline, and 1,3,5‐trimethylbenzene, respectively, while ZJ and AH both contained two unique odor components, respectively: pentyl pentanoate and dill ether (ZJ), myrcene, and 2‐pentadecanone (AH). Moreover, PJH from above five districts could be discerned quickly by FT‐NIR.ConclusionThe application of multidimensional analytical techniques in quality assessment of PJH from different districts in China would provide a new idea for quality control and geographical origin traceability of traditional Chinese materia medica.

Published: January 2025

ABSTRACTA tetrameric coiled‐coil peptide, TetNL, is used herein as a building block for hierarchical assembly into higher order structures. Assembly within phosphate buffer (pH 7.4) led to the rapid formation of micron‐sized fibers and cuboid structures, a process that could be shifted toward cuboid formation with agitation during the assembly process. Investigation of the packing of the cuboid assemblies by TEM demonstrated a regular banding pattern (4.6 nm) within the structures that was perpendicular to the length of the cuboids, a value that supports an end‐to end organization of the tetrameric coiled coils along the blocks. SWAXS analysis supports that the internal packing of the tetrameric coiled coil building blocks is a close‐packed hexagonal structure. These data represent an interesting comparison with a trimeric coiled coil peptide, TriNL, that forms hollow nanotubes with the same internal hexagonal packing. Modified TriNL has been used to generate numerous unique morphologies, and the data presented herein provide a distinct tetrameric building block that can also be exploited in this manner.

Published: January 2025

ABSTRACTThe high nitrogen and high oxygen content of energetic dioxadiazine compounds makes them exhibit high detonation performance and good stability, showing possible application in both military and civilian fields. Energetic dioxadiazine compounds with intramolecular hydrogen bonds were designed and optimized, while introducing —NH2, —NHNO2, —CH3, —NO2, and —OH as modified groups. The bond order, density, enthalpy of formation, stability, detonation performance and inter/intramolecular interactions were analyzed. Results showed that the skeleton of 1,4,2,6‐dioxadiazine and 1,4,2,5‐dioxadiazine had good stability and symmetrical structure. Analysis of bond length revealed the strong hydrogen bonding between the hydroxyl group and dioxadiazine ring. The introduction of —NH2 and —OH groups proved beneficial in increasing molecular planarity. Bond order analysis, molecular electrostatic potential (ESP) analysis and detonation parameter calculations showed that B5 and C5 have good stability and detonation properties. Crystal structure prediction suggested that B5 would most likely crystallize in monoclinic (P21 space group) while C5 would crystallize in orthorhombic (Pbca space group). Hirshfeld surface analysis indicated strong O···H and N···H interactions for compounds B5 and C5. The above results have a positive promoting effect on obtaining high‐energy dioxadiazine compounds with high stability.

Published: January 2025

AbstractThe growing demand for sustainable mango production has driven the search for eco‐friendly alternatives to synthetic chemicals, leading to the exploration of plant‐based biofungicides. This study aims to identify and evaluate these biofungicides, focusing on their in‐silico toxicity and docking properties against the cutinase protein of Colletotrichum gloeosporioides, the pathogen responsible for mango anthracnose. Using computational methods, the potential toxicity of 14 phytochemical compounds was assessed to ensure their safety for nontarget organisms and the environment. Molecular docking simulations were conducted to examine the interaction between the compounds and the cutinase enzyme, a critical factor in the pathogenicity of C. gloeosporioides. The results highlight the potential of certain phytochemicals, particularly limonene and β‐linalool as biofungicides, while also identifying areas for improvement in terms of toxicity and environmental impact. Molecular dynamics simulations were also conducted to examine the behavior of the protein–ligand complexes over time, revealing several key insights. The radius of gyration (Rg) analysis showed a slight increase in Rg values for both limonene and β‐linalool, suggesting moderate destabilization of the protein structure and indicating their potential as inhibitors. Additionally, the root mean square deviation (RMSD) and root mean square fluctuation (RMSF) analyses confirmed that while the compounds led to slight fluctuations in the protein structure, the overall stability, and integrity of the protein were maintained. The binding free energy calculations supported the hypothesis of these compounds acting as effective inhibitors of cutinase, potentially offering an eco‐friendly solution for controlling mango anthracnose.

Published: January 2025

AbstractA lot of interest has been gained recently in developing novel acetylcholinesterase (AChE) inhibitors that can alleviate Alzheimer's symptoms. In the current study, we aimed to explore AChE inhibitory activity of new chromenes attached to 1,3,4‐oxadiazole and/or pyrazole units. The new hybrids were obtained via [3 + 2] cycloaddition reaction between the appropriate chromene‐based enaminones and hydrazonyl chlorides. The inhibition percentages of the new products against AChE were recorded at tested concentrations of 15 and 25 µM compared to donepezil. 3‐(3‐Acetyl‐1‐(4‐methoxyphenyl)‐1H‐pyrazole‐4‐carbonyl)‐6‐(((5‐phenyl‐1,3,4‐oxadiazol‐2‐yl)thio)methyl)‐2H‐chromen‐2‐one displayed promising activity with inhibition percentages of 73.2 and 87.3, respectively, at the aforementioned concentrations. Moreover, the previous hybrid gave promising 2,2‐diphenylpicrylhydrazyl (DPPH) inhibitory activity using the reference ascorbic acid. It had an inhibition percentage of 86.6 at a tested concentration of 25 µM.
