Assuming agents possess sensing capabilities and dynamics relative to their body coordinate frames, this paper addresses a displacement-based strategy for discrete-time formation control through attitude synchronization. Unlike the Eulerian approximation, the first challenge lies in developing discrete-time models that capture both position and attitude motions, thereby complementing existing continuous-time systems with a discretized version. Then, two leader-following control protocols are designed, incorporating a jointly-connected topology to relax the connectivity requirements. The analysis of these systems often relies on the Lyapunov function, the existence of which may be hard to guarantee. Consequently, geometric properties of several polytopes are explored under the dynamic topologies and time-varying parameters. By extending the ergodicity results to leader-following scenarios, these properties are characterized as positively invariant sets. This invariance, which is independent of the existence of the Lyapunov function or the solvability of its associated criteria, provides a beneficial tool for analyzing time-variant systems. Utilizing this invariance and some mathematical techniques, the desired formation shape can be achieved in the cases where the attitudes of the followers synchronize with the leader. Finally, a numerical simulation validates the results. © 2014 IEEE.

Nowadays, ionic liquids (ILs) have extensive applications in biotechnology and are classified as green solvents. However, there are significant concerns over the effect of ILs on microorganism growth, especially towards mixed microorganisms. This study sets out to investigate the effect of synthesized ILs, particularly imidazolium hydrogen sulfate [IM][HSO4] and morpholinium tetrafluoroborate [MOR][BF4], towards mixed culture microorganisms, mainly identified as Bacillus cereus, Bacillus thuringiensis, and Pseudallescheria boydii. The toxicity effect of both ILs is assessed through the disk diffusion method. Moreover, the ecological effects of mixed culture growth on ILs are analyzed by conducting the growth inhibition test in fermentation liquid media. This study reveals that the growth of mixed culture microorganisms started to decline after 4 and 5 h of injecting the [IM][HSO4] and [MOR][BF4], respectively. This shows that mixed culture microorganisms have a longstanding growth and the least inhibition effect after being exposed to [MOR][BF4] rather than [IM][HSO4]. Similar findings are observed regarding the inhibitory effects, with [MOR][BF4] showing a smaller inhibition zone compared to [IM][HSO4]. This finding clearly indicates that imidazolium based ILs are more toxic than morpholinium based ILs. The present study lays the groundwork for further experimental investigation on [MOR][BF4] towards mixed culture microorganisms through the structural characteristics, explicitly focusing on using ILs without the alkyl chain. © 2025 Wiley-VCH GmbH.

Recent advancements in quantum photonics have driven significant progress in photonic quantum computing (PQC), addressing challenges in scalability, efficiency, and fault tolerance. Experimental efforts have focused on integrated photonic platforms utilizing materials such as silicon photonics and lithium niobate to enhance performance. Parameters like photon loss rates, coupling efficiencies, and fidelities have been pivotal, with state-of-the-art systems achieving coupling efficiencies above 90% and photon indistinguishability exceeding 99%. Quantum error correction schemes have reduced logical error rates to below 10-3, marking a step toward faulttolerant PQC. Photon generation has also advanced with deterministic sources, such as quantum dots, achieving brightness levels exceeding 106 photon pairs/s/mW and time-bin encoding enabling scalable entanglement. Heralded single-photon sources now exhibit purities above 99%, driven by innovations in fabrication techniques. High-efficiency photon detectors, such as superconducting nanowire single-photon detectors (SNSPDs), have demonstrated detection efficiencies exceeding 98%, dark count rates below 1 Hz, and timing jitters as low as 15 ps, ensuring precise photon counting and manipulation. Moreover, demonstrations of boson sampling with over 100 photons underscore the growing computational power of photonic systems, surpassing classical limits. The integration of machine learning has optimized photonic circuit design, while frequency multiplexing and time-bin encoding have increased system scalability. Together, these advances bridge the gap between theoretical potential and practical implementation, positioning PQC as a transformative technology for computing, communication, and quantum sensing. © 2025, CC BY.

This study successfully modifies NF2 PES membrane via chemical grafting with methacrylic acid (MAA) at predetermined monomer concentrations, reaction times, and initiator concentrations by means of producing forward osmosis (FO) membrane. The membranes are utilized in the FO system, and performance is discussed in terms of water and solute flux. The surface characteristics of the modified membrane are analyzed in terms of water contact angle, functional groups, and degree of grafting (DG), meanwhile, morphological studies are analyzed via AFM and FESEM characterization. Based on the FO test performance, it can be concluded that increasing monomer concentration results in an increase in the permeate fluxes until a certain value is reached;only then does the permeate flux start to decrease. However, the effect of monomer concentrations is not significant on the permeate flux when shorter reactions are applied. This is probably due to the limitation of reaction time, which only allows certain values at a time for co-polymerization to be completed, hence affecting the permeate flux. Increasing reaction time offers more reactions to occur, leading to more surface grafting activity. However, prolonging the reaction time does not always improve the surface grafting, especially when higher monomer concentration and initiator concentration are involved. © 2025 Wiley-VCH GmbH.

Ceria is a reducible oxide that has been extensively employed as supporting carrier in catalysis due to its unique redox and structural properties in combination with its strong interaction with the active phases. Recently, the synthesis of ceria nanostructures with uniform size and morphology has become a topic of extensive scientific interest in catalysis. Therefore, the combination of earth-abundant and cost-effective transition metals with fine-tuned ceria carriers could provide a platform for multifunctional materials in several energy and environmental applications. Herein, we originally explore the facile synthesis of ceria particles of triangular-like morphology with improved textural and structural characteristics and their subsequent application as supporting carrier of nickel active phase. The as-prepared Ni/CeO₂ catalysts were thoroughly characterized and catalytically assessed for both oxidation (CO oxidation) and reduction (CO₂ hydrogenation) processes to demonstrate the effectiveness of ceria triangular structures as supporting materials in catalysis. The results clearly revealed the pivotal role of ceria nanostructure on the physicochemical properties and in turn on the catalytic performance of the nickel-ceria binary system. The improved reducibility and oxygen kinetics of ceria carrier, along with its abundance in structural defects and Ce³⁺ species, could be considered as the dominant factors towards determining the catalytic performance, offering highly active and selective ceria-based transition metal catalysts. © 2025 The Authors

Hybrid activated carbon/ maltodextrin-functionalized fibrous silica for acetaminophen and amoxicillin adsorption: Advanced statistical physics modelling

引用

Environmental Research 2025年 278卷

作者： Sukor, Nuramira Fateha Jusoh, Rohayu Faculty of Chemical and Process Engineering Technology Universiti Malaysia Pahang Al-Sultan Abdullah Lebuh Persiaran Tun Khalil Yaakob Pahang Kuantan26300 Malaysia Centre for Research in Advanced Fluid & Processes Universiti Malaysia Pahang Al-Sultan Abdullah Lebuh Persiaran Tun Khalil Yaakob Pahang Gambang26300 Malaysia

A novel hybrid adsorbent of activated carbon/maltodextrin-functionalized fibrous silica (AC/KCC-1/DEX) was prepared for the efficient removal of Acetaminophen (ACE) and Amoxicillin (AMOX) from water. Comprehensive characterization via FESEM, TEM, BET, XPS, and FTIR confirmed an enhances surface properties and functional corporation from supporting materials and functionalization agent. Particularly, despite significant decrease in surface area upon DEX functionalization, a remarkable enhancement in adsorption removal efficiency was observed, underscoring the pivotal role of surface chemistry over surface area alone. The AC/KCC-1/DEX exhibited 87.64 m2/g and 122.94 m2/g of micropore and mesopores surface area, respectively, along with reactive functional group of DEX such as –OH, which increase surface polarity and enables strong interactions with polar pharmaceuticals. This innovative material evinced high adsorption capacity of 87.97 mg/g and 77.31 mg/g for ACE and AMOX, respectively, achieving percentage removal of 94 % and 81 %, correspondingly. Adsorption kinetics were best described by the Elovich model, suggesting heterogenous surface interactions, while Redlich-Peterson isotherm favoured physisorption. Advanced statistical physics modelling with key steric parameters provided further mechanistic insights at a molecular level, revealing a multilayer physisorption mechanism with additional chemisorption contributions. Thermodynamic analysis supported the spontaneity and exothermic nature of the process, with negative Gibbs free energy (ΔG) and enthalpy (ΔH) values, while a negative entropy change (ΔS), proposed increased order at the solid-liquid interface, indicative of strong adsorbate-adsorbent affinity and potential chemisorption effects. This study not only demonstrates the effectiveness and adsorption behaviour of AC/KCC-1/DEX but also opens new avenues for sustainable water treatment solutions. © 2025 Elsevier Inc.

作者： Schoenborn, Sabrina Yuan, Mingyang Fell, Cody A Liu, Chuanhai Fletcher, David F Priola, Selene Chan, Hon Fai Woodruff, Mia Li, Zhiyong Toh, Yi-Chin Allenby, Mark C St LuciaQLD4072 Australia Centre for Biomedical Technologies School of Mechanical Medical and Process Engineering Queensland University of Technology Kelvin GroveQLD Australia Key Laboratory for Regenerative Medicine of the Ministry of Education of China School of Biomedical Sciences Faculty of Medicine Institute for Tissue Engineering and Regenerative Medicine The Chinese University of Hong Kong Shatin Hong Kong Center for Neuromusculoskeletal Restorative Medicine Hong Kong Special Administrative Region of China Hong Kong School of Chemical and Biomolecular Engineering University of Sydney DarlingtonNSW2006 Australia Department of Biomechanical Engineering Faculty of Mechanical Engineering Delft University of Technology Delft Netherlands

Big mechanically-active culture systems (BigMACS) are promising to stimulate, control, and pattern cell and tissue behaviours with less soluble factor requirements. However, it remains challenging to predict if and how distributed mechanical forces impact single-cell behaviours to pattern tissue. In this study, we introduce a tissue-scale finite element analysis framework able to correlate sub-cellular quantitative histology with centimetre-scale biomechanics. Our framework is relevant to diverse BigMACS, including media perfusion, tensile-stress, magnetic, and pneumatic tissue culture platforms. We apply our framework to understand how the design and operation of a multi-axial soft robotic bioreactor can spatially control mesenchymal stem cell (MSC) proliferation, orientation, differentiation to smooth muscle, and extracellular vascular matrix deposition. We find MSC proliferation and matrix deposition to positively correlate with mechanical stimulation but cannot be locally patterned by soft robot mechanical stimulation within a centimetre scale tissue. In contrast, local stress distribution was able to locally pattern MSC orientation and differentiation to smooth muscle phenotypes, where MSCs aligned perpendicular to principal stress direction and expressed increased α-SMA with increasing 3D Von Mises Stresses from 0 to 15 kPa. Altogether, our new biomechanical-histological simulation framework is a promising technique to derive the future mechanical design equations to control cell behaviours and engineer patterned tissue. © 2025 The Author(s).
