Stochastic distributed tracking of heterogeneous multi‐agent systems with Markovian switching topologies and infinite delays
Authors: Guo Haihua , Feng Gang , Bi Cong 
Published: October 2024

AbstractThis article investigates the distributed mean square output tracking problem of heterogeneous multi‐agent systems with Markovian switching topologies and infinite transmission delays. The main challenge of the concerned problem arises from how to deal with Markovian switching topologies and infinite transmission delays simultaneously. A novel distributed observer is developed based on a newly proposed Lyapunov functional method. Then, a distributed controller based on the distributed observer is developed. It is shown that the stochastic distributed tracking problem is solved in the sense of mean square if the union graph of the underlying Markovian switching topology contains a spanning tree. A distinctive feature of the proposed controller is that the infinite delays are not required to be known. Finally, the effectiveness of the proposed controller is illustrated by two numerical examples.

Authors: Adomako Samuel , Tran Mai Dong 
Published: October 2024

AbstractDespite extensive research into the factors driving sustainable innovation, there remains a significant gap in understanding the impact of intellectual property rights (IPR) protection. This study delves into how IPR protection influences sustainable innovation performance and explores the mechanism of technology spillover and the condition of absorptive capacity. Analyzing data from 266 firms in Vietnam, our findings indicate a positive correlation between IPR protection and technology spillover. Additionally, we find that technology spillover mediates the relationship between IPR protection and sustainable innovation performance. Interestingly, we show that absorptive capacity bolsters the relationship between technology spillover and sustainable innovation performance. These insights offer valuable additions to the existing literature on IPR protection and sustainable innovation literature. Implications for both theory and practice are discussed in detail.

Published: October 2024

AbstractIn this study, a green and sustainable approach using visible light photocatalysis was employed for synthesizing N‐benzyl aniline derivatives to create C─N bonds. A TiO2 photocatalyst doped with copper and lanthanum was prepared to reduce the band gap and increase surface area. TixCuyOz and TixCuyLamOz nano‐photocatalysts were designed efficiently for organic reactions. Characterization techniques included TEM, FE‐SEM, XRD, EDX, FT‐IR, BET, BJH, UV–vis, ICP‐MS, CV, PL, and TPC. Using visible light as a renewable source, these photocatalysts showed high activity and recyclability up to five times, with TixCuyLamOz displaying superior performance due to increased lanthanide content.

Published: October 2024

AbstractA green and efficient method for the preparation of spirooxindole‐linked fused pyrans has been developed utilizing a catalyst‐free visible‐light‐driven one‐pot multicomponent reaction strategy. The reaction was performed in a water and ethanol mixture, using the combination of isatin, malononitrile, and cyclic 1,3‐dicarbonyls such as 4‐hydroxy‐1‐methyl‐2(1H)‐quinolone, 4‐hydroxycoumarin, 4‐hydroxythiocoumarin, or barbituric acid derivatives. This catalyst‐free, environmentally friendly, visible‐light‐driven, and room temperature method is a valuable addition to the synthetic toolbox for constructing complex heterocyclic scaffolds under one‐pot conditions. It holds promise for future applications in medicinal chemistry and drug discovery.

AbstractPreparation of in‐house reference materials of two different graded coal samples involves quality control in terms of chemical characterization. Neutron and proton‐based nuclear analytical techniques have been explored here using high flux nuclear research reactor and low energy proton accelerator. Concentrations of trace elements such as Sc, Cr, Fe, Co, Sb, Ce, Th, U, Eu, Hf, and Rb were determined by neutron activation analysis (NAA) with adequate accuracy and precision. Coal ash content can be derived from the inorganic oxide constituents (Na2O, MgO, Al2O3, SiO2, Fe2O3, TiO2, K2O and CaO). Coal‐1 was found to contain slightly higher ash content (∼35%) with low calorific value (C content ∼49% obtained from, pulsed fast and thermal neutron activation [PFTNA]) as compared to coal‐2 (∼33%). Ion beam analysis (IBA) technique (particle induced gamma‐ray emission [PIGE]) was utilized for quantification of inorganic major elements. Thermal and fast neutron probed nuclear methods like NAA using pneumatic carrier facility (PCF) and PFTNA in conjunction with IBA have proved their excellence for nondestructive chemical characterization. Energy dispersive X‐ray fluorescence (EDXRF) was also utilized as an alternate analytical technique for concentration determination of K, Ca, Fe, Ti, Zn, and Rb as a part of QC exercise.

Published: October 2024

AbstractPhosphorous‐based polymeric scale and corrosion are widely used for industrial water treatment. In this paper, phosphorous acid modified polyamidoamine dendrimer (PDD) was prepared for scale inhibition and corrosion inhibition and compared with the existing inhibitors, 2‐phosphonobutane‐1,2,4‐tricarboxylic acid (PBTCA) and polyacrylic. The scale inhibition efficiency of CaCO3 was evaluated using the static scale inhibition and conductivity method. Compared to polyacrylic acid, the dendritic structure can effectively improve the calcium carbonate scale inhibition performance of the scale inhibitor. When the concentration of PDD is 40 mg/L, the scale inhibition rate is 96%, which is higher than the scale inhibition rate of 91% for PBTCA. The conductivity experimental results reveal that PDD endows the solution with higher supersaturation degree than that of PBTCA at the same concentration. Furthermore, the nucleation induction period of PDD is 1300 s, which is more than twice that of PBTCA at a concentration below 20 mg/L. The XPS, XRD, and SEM results exhibited that PDD can adsorb on the surface of calcium carbonate crystals, changing the crystals from stable calcite to metastable aragonite and vaterite. In addition, electrochemical measurements show a corrosion inhibition rate of 82.67% at a PDD concentration of 100 mg/L. This article provides data support for the application of phosphorous acid functionalization PAMAM in scale and corrosion inhibition.

Published: October 2024

AbstractCurrently, carbon nanomaterials are found to possess various shapes and sizes, where their potentiality is mainly governed by the functional groups and design parameters. The alteration of the material features through postprocessing or reformulation can produce these nanostructures for utilization in air/wastewater treatment, dyes, pharmaceuticals, pesticides, and so forth. In this work, three isomeric structures of toluidine were chosen, which contain a ─CH3 at the o‐, m‐, and p‐positions of the benzene ring along with an ─NH2 group. SEM and TEM images confirmed the formation of carbon nanoparticles at different times and temperatures under optimized reaction conditions. It was observed that uniform size of carbon quantum dots was obtained from all the isomeric structures, namely, after 60, 90, and 60 min in case of o‐, m‐, and p‐toluidine, respectively. The efficiency of the synthesized carbon nanoparticles for the degradation of toxic organochlorine pesticides, namely DDT, lindane, and fenvalerate was also studied. Interestingly, the synthesized carbon quantum dots were found to degrade the DDT up to 98.5%, lindane up to 83.02%, and fenvalerate up to 74.34% under visible light exposure. However, only 63.23%, 20.25%, and 30.41% degradation were observed under dark conditions for DDT, lindane, and fenvalerate, respectively.
Modifications in Subsurface of Catalysts: Impact of Bringing in Electrophilicity on Catalytic Applications
Authors: Khan Safia , Li Hu 
Published: October 2024

AbstractSurface, interface, and subsurface in catalysts are broadly perceived as independent units in materials, relying on diverse bonding environments and are recurrently studied discretely because of experimental challenges in distinguishing the surface and subsurface effects. Metal crystals, isolated atoms, or metal nanoparticles in supported catalysts induce an electrophilic nature in subsurface, enhancing the catalysis efficiency. In this review, the influence of modification in subsurface of catalysts and their specific catalytic outputs are discussed. Key approaches and techniques for insertion of subsurface modifications and impact of electrophilicity upon catalysis upgradation are observed. A compilation of frequently used chemical reactions catalyzed by subsurface‐modified catalysts have been structured and thoroughly illustrated.
Examining hypothalamic‐pituitary‐adrenal axis genetic variation on cortisol and alpha‐amylase reactivity during an explicit negative‐evaluative stress induction
Authors: Grillo Alessandra R. , Starr Lisa R. , Vrshek‐Schallhorn Suzanne 
Published: October 2024

AbstractPrior work consistently links additive genetic variation in the hypothalamic‐pituitary‐adrenal (HPA) axis—a multilocus genetic profile score (MGPS)—to depression risk in the context of stress exposure. However, despite that HPA MGPS variants were selected based on evidence that they elevate cortisol reactivity, there are surprisingly few tests of whether an HPA MGPS elevates cortisol reactivity to lab‐based stress. Similarly, despite neurobiological connections and coordination between the HPA axis and the sympathetic nervous system (e.g., in the paraventricular nucleus and locus coeruleus), no work has tested whether an HPA MGPS influences sympathetic nervous system reactivity to stress. We investigated whether an HPA MGPS moderates the relation between lab‐based stress and: (1) HPA activity indexed by cortisol, and/or (2) sympathetic activity indexed by salivary alpha‐amylase, sAA. Emerging adults (N = 152; mean age = 19.5, largest subsample 44.4% Black/African American) were randomly assigned to one of two Trier Social Stress Test variations, a non‐evaluative control, or an explicitly negative‐evaluative condition. Participants provided DNA and repeated saliva samples for sAA and cortisol. The HPA MGPS did not significantly moderate the relationship between stress condition and cortisol or sAA reactivity, respectively; moreover, post‐hoc tests highlight that individual polymorphisms showed non‐significant effects in opposite directions from each other, cancelling out in aggregate. Findings suggest that the HPA MGPS's associations with cortisol reactivity are not as straightforward as initially believed. We speculate that the relationships of some HPA variants to biomarker reactivity may vary between modest lab‐based stressors and the explicit negative‐evaluative induction used here.

AbstractCommercial metalized plastic current collector (MPCC) is receiving widespread attention from the business and academic communities, due to its properties of excellent electrical conductivity and low mass density. However, the application of MPCC on the side of copper is rarely studied. Herein, sandwich‐like polyethylene terephthalate‐based (PET) and polypropylene‐based (PP) copper (Cu) current collectors via magnetron sputtering and electroplating are fabricated. Most importantly, the electrical performance, mechanical safety quality, and revealed the corresponding failure mechanism for the MPCC cells are first systematically evaluated. First, during the 45 °C electrical cycling tests, PET‐Cu CC (82.67%) and PP‐Cu CC (82.32%) cells both have comparable capacity retention with the traditional Cu CC (Tra‐Cu CC) cell (84.55%) after 500 cycles. The slight reduction in the cycling performance is induced by the crack of the Cu layer around the embedded SiO2 particle for PET‐Cu CC cell and the detachment of Cu layer for PP‐Cu CC cell. Second, during the nail‐penetration test, MPCC cells maintain no fire and explosion for more than 5 min, since the heat‐shrinkable function of polymeric film can interrupt the continuous Joule heat released by internal short‐circuit. This work provides important guidance for the large‐scale application of MPCC in the field of lithium‐ion batteries.

Published: October 2024

AbstractComposite solid electrolytes (CSEs) have become one of the most promising solid‐state electrolytes due to their favorable safety and flexibility. However, the weak interaction between inorganic fillers and polymer matrix leads to poor organic–inorganic interfacial compatibility, which degrades the electrochemical performance of CSEs. Herein, it is demonstrated that Li6.4La3Zr1.4Ta0.6O12 (LLZTO) can be chemically bonded to the polymer matrix by surface coordination of the 1,2‐dithiolane group of lipoic acid (LA) with metal atoms on the surface of LLZTO through a combination of experimental investigations and theoretical calculations. The surface coordination not only enhances the interfacial compatibility between LLZTO and the polymer matrix, but also facilitates rapid Li+ transport, which leads to the ionic conductivity of the prepared CSE (P‐V‐M@LLZTO) as high as 6.1 × 10−4 S cm−1 at 30 °C. The excellent interface compatibility ensures a stable cycle of Li/P‐V‐M@LLZTO/Li symmetrical cell for more than 3500 h. As a result, LiFePO4/P‐V‐M@LLZTO/Li cell delivers the discharge capacity of 161 mAh g−1 after 5 cycles with a capacity retention of 81% after 500 cycles at 0.5C under 30 °C. This work demonstrates that surface coordination is an effective strategy to solve the inherent interfacial incompatibility problem in CSEs.

Published: October 2024

AbstractThe layer‐structured oxide cathode for sodium‐ion batteries has attracted a widespread attention due to the unique redox properties and the anionic redox activity providing additional capacity. Nevertheless, such excessive oxygen redox reactions will lead to irreversible oxygen release, resulting in a rapid deterioration of the cycling stability. Herein, sulfur ion is successfully introduced to the O3‐NaNi0.3Mn0.5Cu0.1Ti0.05W0.05O2 material through high‐temperature quenching, thereby developing a novel Na2S‐modified O3/P2‐NaNi0.3Mn0.5Cu0.1Ti0.05W0.05O2 composite with extended cycling life. The S2− is analyzed for the ability to enhance the reversibility of oxidation‐reduction reactions under high voltage and suppress the loss of lattice oxygen during cycling. The stable S─O covalent bonds are found to inhibit the oxygen generation and release within the structure. Benefiting from these improvements, the Na₂S‐modified O3/P2‐NaNi0.3Mn0.5Cu0.1Ti0.05W0.05O2 exhibited a high reversible capacity of 173.1 mA h g−1 over a wide voltage range of 1.5–4.3 V under test conditions at 0.1 C and 81.5% capacity retention after 120 cycles at 1 C. The Na₂S‐modified O3/P2‐NaNi0.3Mn0.5Cu0.1Ti0.05W0.05O2 demonstrates the excellent rate capability with the reversible capacities of 173.1,137.0,114.7,96.7, and 80.1 mA h g−1 at 0.1, 0.2, 0.5, 1, and 2 C.

Published: October 2024

AbstractGraphitic carbon nitride (gC3N4) is an attractive photocatalyst for solar energy conversion due to its unique electronic structure and chemical stability. However, gC3N4 generally suffers from insufficient light absorption and rapid compounding of photogenerated charges. The introduction of defects and atomic doping can optimize the electronic structure of gC3N4 and improve the light absorption and carrier separation efficiency. Herein, the high efficiency of carbon nitride photocatalysis for hydrogen evolution in visible light is achieved by an S‐modified double‐deficient site strategy. Defect engineering forms abundant unsaturated sites and cyano (─C≡N), which promotes strong interlayer C─N bonding interactions and accelerates charge transport in gC3N4. S doping tunes the electronic structure of the semiconductors, and the formation of C─S─C bonds optimizes the electron‐transfer paths of the C─N bonding, which enhances the absorption of visible light. Meanwhile,C≡N acts as an electron trap to capture photoexcited electrons, providing the active site for the reduction of H+ to hydrogen. The photocatalytic hydrogen evolution efficiency of SDCN (1613.5 µmol g−1 h−1) is 31.5 times higher than that of pristine MCN (51.2 µmol g−1 h−1). The charge separation situation and charge transfer mechanism of the photocatalysts are investigated in detail by a combination of experimental and theoretical calculations.

Published: October 2024

AbstractRechargeable Zn–air batteries (ZABs) hold promise as the next‐generation energy‐storage devices owing to their affordability, environmental friendliness, and safety. However, cathodic catalysts are easily inactivated in prolonged redox potential environments, resulting in inadequate energy efficiency and poor cycle stability. To address these challenges, anodic active sites require multiple‐atom combinations, that is, ensembles of metals. Heterogeneous bimetallic atomically dispersed catalysts (HBADCs), consisting of heterogeneous isolated single atoms and atomic pairs, are expected to synergistically boost the cyclic oxygen reduction and evolution reactions of ZABs owing to their tuneable microenvironments. This minireview revisits recent achievements in HBADCs for ZABs. Coordination environment engineering and catalytic substrate structure optimization strategies are summarized to predict the innovation direction for HBADCs in ZAB performance enhancement. These HBADCs are divided into ferrous and nonferrous dual sites with unique microenvironments, including synergistic effects, ion modulation, electronic coupling, and catalytic activity. Finally, conclusions and perspectives relating to future challenges and potential opportunities are provided to optimise the performance of ZABs.

AbstractPhotocatalytic generation of H₂O₂, involving both oxygen reduction and water oxidation without sacrificial agents, necessitates maximized light absorption, suitable band structure, and efficient carrier transport. Leveraging the redox capacity this study designs and constructs a step‐scheme heterostructured SnO₂/Zn₃In₂S₆ catalyst for H₂O₂ production from seawater under ambient conditions for the first time. This photocatalyst demonstrates a remarkable H₂O₂ production rate of 43.5 µmol g⁻¹ min⁻¹ without sacrificial agents, which can be increased to 80.7 µmol g⁻¹ min⁻¹ with additional O₂ injection. Extensive in situ and ex situ characterizations, supported by theoretical calculations, reveal efficient carrier transport and robust redox ability, enabling complete photosynthesis of H₂O₂ at the oxidation and reduction sites in the S‐scheme SnO₂/Zn₃In₂S₆ heterojunction. Furthermore, it is hypothesized that substituting SnO₂ with other semiconductors such as TiO₂, WO₃, and BiVO₄ can all form S‐scheme and the results confirm the feasibility of such catalyst design. Additionally, it demonstrates the recycling and further utilization of the H₂O₂ produced. These findings offer new insights into the design of heterostructure catalyst architectures and present new opportunities for H₂O₂ production from seawater at ambient conditions without sacrificial agents.

Published: October 2024

AbstractSymmetrical batteries hold great promise as cost‐effective and safe candidates for future battery technology. However, they realistically suffer low energy density due to the challenge in integrating high specific capacity with high voltage plateau from the limited choice of bipolar electrodes. Herein, a high‐voltage all‐V2O5 symmetrical battery with clear voltage plateau is conceptualized by decoupling the cathodic/anodic redox reactions based upon the episteme of V2O5 intercalation chemistry. As the proof‐of‐concept, a hierarchical V2O5‐carboncomposite (VO‐C) bipolar electrode with boosted electron/ion transport kinetics is fabricated, which shows high performance as both cathode and anode in their precisely clamped working potential windows. Accordingly, the symmetrical full‐battery exhibits a high capacity of 174 mAh g−1 along with peak voltage output of above 2.9 V at 0.5C, remarkable capacity retention of 81% from 0.5C to 10C, and good cycling stability of 70% capacity retention after 300 cycles at 5C. Notably, its energy density reaches 429 Wh kg−1 at 0.5C estimated by the cathode mass, which outperforms most of the existing Li/Na/K‐based symmetrical batteries. This study leaps forward the performance of symmetrical battery and provides guidance to extend the scope of future battery designs.
