Orthophosphate and phosphonate often co-exist in industrial wastewater, and it is a challenge to remove the above inorganic and organic phosphorus simultaneously to meet the stringent total phosphorus (TP) discharge standard. The kaolin-based lanthanum carbonate (LC) composites have been demonstrated to decontaminate TP (PO43− and HEDP) from RO concentrate effectively, while the individual and simultaneous adsorption behavior and mechanisms are still not clear. In this study, the individual and simultaneous PO43− and HEDP adsorption were compared. The adsorption kinetics, isotherms, initial pH and matrix effects were performed. The results showed that PO43− exhibited a nice adsorption performance, and was severely suppressed in the presence of HEDP. The maximum adsorption capacities were obtained at initial pH of 4.0, and the co-existing Ca2+ significantly enhanced both PO43− and HEDP removal, while HCO3−/CO32− markedly interfered with their adsorption process. LaCO3OH was the main composition in the KLC composites for PO43− and HEDP adsorption, and no La-P compounds formed after adsorption. A variety of characterization methods were adopted to explore the adsorption mechanisms, and electrostatic attraction, inner-sphere complexation and hydrogen bond were responsible for PO43− and HEDP adsorption. The DFT calculations were applied to distinguish the PO43− and HEDP adsorption from the molecular level, and the configuration of H2HEDP-BB with higher adsorption energy (-165.42 KJ/mol) resulted in the predominant species of HEDP in the competitive adsorption. In the fixed-bed column experiments, both PO43− and HEDP adsorption capacities decreased in the binary system compared with that in the single system, which also matched the results of batch experiments and DFT calculations. This study provides insights into the competitive adsorption of orthophosphate and phosphonate by LC-based sorbent. © 2023, The Authors. All rights reserved.

We report the facile synthesis of Fe 3 O 4 @Au core/shell nanoechinus through a template-free liquid-liquid interfacial growth reaction. The prepared magneto-plasmonic Fe 3 O 4 @Au core/shell nanoechinus exhibited outstanding SPR absorption in the NIR region, which imparts the nanoechinus with a superior photothermal conversion efficiency of 69.9%, making this material an efficient photothermal agent for antibacterial application. Our results indicated that the magneto-plasmonic Fe 3 O 4 @Au core/shell nanoechinus could effectively kill both Gram negative E. coli and Gram positive S. aureus under 980 nm laser irradiation and kept good photo-stability after multiple photothermal bacteria killing. We envision that the development of advanced strategy for high efficient antibacterial hybrid nanoparticles could have broad applications in therapy and medical devices. © 2022, The Authors.

Thermal management in the mid-infrared (MIR) range is gaining critical importance across diverse applications, such as in energy-efficient architecture and sophisticated electronic thermal regulation. However, traditional materials are often constrained by insufficient thermal conductivity, limited spectral flexibility, and susceptibility to degradation under extreme conditions, all of which undermine their effectiveness in the MIR domain. Although two-dimensional (2D) materials, including graphene, hexagonal boron nitride (h-BN), and transition metal carbides/nitrides (MXenes), have garnered considerable attention for addressing these limitations, a thorough understanding of their structural advantages specific to MIR thermal management remains scarce. This review seeks to bridge this gap by offering a detailed structural analysis of these 2D materials within the context of MIR applications. Initially, the inherent structural features of graphene, h-BN, and MXenes are examined, illustrating how these enable advanced MIR functionalities, such as efficient radiative heating, cooling, and dynamic modulation. Subsequently, an in-depth evaluation of their performance across various application areas is provided, including thermal radiation control and spectral regulation, with insights into their domain-specific advantages. Finally, also explores the challenges and proposes future directions, highlighting structural design strategies aimed at enhancing their applicability in MIR thermal management. This review not only underscores the unique potential of 2D materials but also provides a strategic framework to inform future research and innovation in MIR thermal management technologies. © 2025 IOP Publishing Ltd.

The uncontrollable growth of lithium dendrites and low columbic efficiency in liquid electrolytes seriously impede the development of high-performance lithium-metal batteries. The emerging approach of in-situ polymerization of solid polymer electrolytes (SPEs) based on 1,3-dioxolane (DOL) provides a new method of solving the high interfacial impedance and unstable long cycling performance of Lithium metal battery. Until now, the role of Lewis acid catalysts on the DOL polymerization has only been limited as the catalyst, nevertheless their alloying ability with Li metal has been ignored, which is important to the formation of artificial SEI as additives. Here, InF3 catalyst was adopted to simultaneously initiate the polymerization of DOL and construct a LiF/LixIn based composite SEI layer through its reaction with Li metal. Electrochemical measurement results show that its oxidation potential is up to 4.5V and the Li+ transference number is 0.39. Compared with SnF2 catalyst and commercial electrolyte, PDOL with InF3 catalyst show lower interfacial resistances, much uniform lithium deposition and higher Li plating/striping efficiencies. After 500 cycles at 0.5C, the assembled Li/LiFePO4 solid battery delivers a 118mAh/g and 75% capacity retention, with high average Coulombic efficiency of 99.9%. This innovative and facile strategy of dual functional InF3 on the in-situ polymerization of DOL and SEI formation provides new ideas for design solid polymer electrolytes. © 2023, The Authors.

Component leaching plays a pivotal role in enhancing the activity and stability of high-entropy-based catalysts by triggering structural reconstruction during the oxygen evolution reaction (OER). In this study, we employed soluble V and Mo as sacrificial components alongside a Co stabilizer to synthesize NiFeCoVMo high-entropy catalysts, aiming to simultaneously modulate the reconstruction behavior and optimize catalytic performance. The synergistic interplay between dual-component dissolution and in situ deposition/adsorption mechanisms accelerates structural evolution, ultimately yielding MoO42−-modified NiFeCo oxyhydroxide (NiFeCoOOH-MoO42−). Mechanistic studies reveal that the NiFeCo-based system is particularly conducive to the reconstruction process, while adsorbed MoO42− function as electronic modulators that redistribute charge densities within the reconstructed layers and reduce surface energy. As a result, this reconstructed catalyst demonstrates exceptional OER activity, achieving an overpotential of 172 mV at 10 mA cm−2, along with remarkable long-term durability (up to 500 h at 50 mA cm−2). This study provides fundamental insights into the origins of the superior electrocatalytic performance of high-entropy materials, paving the way for further exploration and optimization of these advanced catalysts. © 2025

Path planning and tracking control are important modules of mobile robots, which have outstanding advantages in improving the flexibility of mobile robots. However, in the existing applications, these two modules are usually processed separately, which makes the obstacle avoidance process of the mobile robot uncontrollable and reduces the adaptability of the application scenario. In order to realize collision-free high-precision trajectory tracking control of mobile robots in dynamic scenes, this paper proposes an adaptive MPC control method based on curvature constraints, which can improve the safety of operation and reduce the chattering caused by unreasonable paths in the process of operation. Firstly, according to the kinematic constraints of general mobile robots, the constraint model of mobile robot path planning is constructed. At the same time, the adaptive parameter adjustment rules are adopted to realize the balance between the calculation efficiency and the control cycle. Finally, a smooth safe path is obtained by re-fitting the planned path and reprocessing the nodes with excessive curvature. Compared with traditional methods, the proposed method has better advantages.

Desalination and purification of seawater and wastewater has been considered as an effective strategy to alleviate water shortage. Interfacial solar steam generation utilizing biomass materials as the core of the evaporator has drawn considerable awareness of its distinctive natural structure. Herein, we report a biomass solar evaporator composed of a convenient and reinforced water transport device using carbonized Pleurotus eryngii (C-PE). Benefiting from the microporous carbon skeleton and microchannels, the as-prepared device exhibits excellent water transpiration and rapid evaporation. The hierarchically porous structure of C-PE could entice interior multiple light reflection to enable all-directional light absorption (> 91.7%) and enhance the capability of photothermal conversion. This device shows a high evaporation rate of 1.22 kg m-2 h-1 under 1 kW m-2 power density. Moreover, the high efficiencies of 81.7% under 1 kW m-2 and 95.1% under 4 kW m-2 for C-PE evaporator were attained. Furthermore, using C-PE for extraction of potable condensed water from wastewater samples containing Na+ , heavy metal ions, dyes, and oil shows a promising potential in terms of cost and sewage treatment. The multiple advantages of high evaporation efficiency and wastewater purification endow the C-PE evaporator available for future bio-derived solar-thermal materials and desalination applications. © 2022, The Authors.

In-situ polymerization of gel polymer electrolytes (GPEs) is expected to be promising approach to solve the safety and interfacial problems of lithium ion battery, but it is still challenging ways to tradeoff the high electrochemical properties and mechanical toughness. Here, 30 um thickness of free-standing GPEs with extremely high monomer conversion were obtained by in-situ UV approach on lithium metal anode within only few seconds. The coordination of amide and aliphatic carbonyl groups with lithium ion endows the tough mechanical properties, which tensile strength and elongation at break reach up to ~1.0 MPa and ~920%. Furthermore, the inflammability of dry polymer matrix and a good degree of graphitization on the surface of burned polymer gel contribute to its flame resistance. The ionic conductivity and lithium ion transfer at room temperature are up to 1.03 mS/cm and 0.44, respectively. Finally, Li/LiFePO4 half cells assembled with the optimized GPEs exhibit high charge/discharge efficiency and stable cycle performance at 0.5C rate, delivering 77.44% of capacity retention and 97.41% of columbic efficiency after 1000 cycles. © 2023, The Authors.
