Addressing global climate change and resource scarcity's dual pressures requires innovative thermal management technologies to enhance energy efficiency and sustainability. Mid-infrared dynamic control plays a pivotal role in advancing thermal management technologies by facilitating efficient radiative cooling and heating, thereby enhancing energy conservation and optimizing thermal regulation in diverse applications. However, current research predominantly emphasizes device architecture over the essential relationship between material structure and function, leading to ambiguity in the selection of materials for specific dynamic applications. This review provides an in-depth analysis from a materials science perspective, systematically categorizes mid-infrared dynamic materials including thermally, electrically, mechanically, and other mechanism-induced materials, and discusses their structural properties, preparation methods, and practical performance. By exploring the intricate interplay between material, structure, and mid-infrared performance in typical applications such as radiative cooling, heating, and dynamic radiation regulation, novel insights into optimizing material selection and design are offered. The materials-focused perspective underscores the importance of understanding the structure-function relationship to enhance application performance, aiming to inspire future research and practical advancements in high-performance, energy-efficient thermal management technologies. © 2025 Elsevier Ltd

1,3-dioxolane (DOL) shows low interfacial impedance and high Coulombic efficiency, thus its polymer electrolytes have attracted extensive attention. However, LiTFSI is still dominantly used in DOL electrolyte due to its low dielectric constant. Totally replacement of LiTFSI with low cost of LiPF6 could bring the heat explosion and high viscosity when mixing DOL with 0.9M LiPF6 electrolyte (carbonate ester solvent). Therefore, a new type of Lewis base, pyridine, is added into DOL to prepare in-situ gelling polymer electrolytes (GPEs). It is demonstrated that monomer conversion and electrochemical window stability is inversely related with the pyridine addition, which are up to 85.2% and 4.5V, respectively. The optimized conductivity and transfer number are 0.99x10-3 S/cm (25 oC) and 0.68, respectively. The stable interface between PDOL and lithium metal anode could be proved by the stable over-potential (50mv, 700 hours) at current density of 0.5 mA cm−2. After 500 cycles at 2 C, the assembled Li/PDOL@py0.125/LiFePO4 battery delivers 115 mAh/g and 90% capacity retention, with high average Coulombic efficiency of 99.83%. The present results demonstrate the heat suppression role of pyridine toward mixing DOL with 0.9M LiPF6 electrolyte, which solves the heat and viscosity problems for PDOL based gelling polymer electrolytes. © 2024, The Authors.

Tin oxide (SnO2) has been demonstrated as a promising electron transport material for high efficiency perovskite solar cells (PSCs) that made entirely via solution processing at low temperature (2|perovskite lead to a large voltage loss and performance variation. Herein, we present a facile and effective method to simultaneously reduce the interfacial defects and enhance the charge transfer via modification of SnO2 by hypervalent potassium xanthate. The presence of Lewis acidic centers of the sulfur ligands, gives rise to a strong hypervalent interactions with both Pb2+ on the perovskite and Sn4+ on the SnO2 surface, which accelerates the interfacial charge transfer and suppresses the recombination reaction. As a result, solar cells with a power conversion efficiency of 23.4% with negligible hysteresis are fabricated in light of significantly increased voltage in comparison with the relevant controls. Moreover, a stabilized efficiency of 18.8% for large-area (active area: 48.0 cm2) perovskite solar modules is achieved. The modules retain 90% of their initial performance after aging at ambient for 600 hours, which is substantially improved in comparison with the modules based on pristine SnO2 © 2022, The Authors.

Although the electronic state of catalysts is strongly corrected with their oxygen evolution reaction (OER) performances, understanding the role of spin state in dynamic electronic structure evolution during OER process is still challenging. Herein, we developed a spin state regulation strategy to boost the OER performance of CoOOH through elemental doping (CoMOOH, M=V, Cr, Mn, Co and Cu). Experimental results including magnetic characterization, in situ X-ray absorption spectroscopy, in situ Raman and density functional theory calculations unveil that Mn doping could successfully increase the Co sites from low spin state to intermediate spin state, leading to the largest lattice distortion and smallest energy gap between d xy and d z 2 orbitals among the obtained CoMOOH electrocatalysts. Benefiting from the promoted electron transfer from d xy to d z 2 orbital, facilitated formation of active high-valent *O−Co (IV) species at applied potential, and reduced energy barrier of rate-determining step, the CoMnOOH exhibits the highest OER performance. Our work provides significant insight into the correction between dynamic electronic structure evolution and OER performance by understanding the role of spin state regulation in metal oxyhydroxides, paving a new avenue for rational design of high-activity electrocatalysts.

Metallic biomaterials are widely used as short and long-term implantable devices by virtue of their outstanding mechanical properties, such as high load-bearing capacity and fatigue resistance. Due to their inherent bioinertness, potential corrosion, and some inferior surface properties, metallic biomaterials generally require coating and surface modification to improve their function and extend their lifespan in the body. High entropy alloys (HEAs) are a novel class of materials that are composed of at least five principal metallic elements with equiatomic or close-to-equiatomic compositions. Some of the unique properties of HEAs for surface modification and coating include excellent corrosion resistance, remarkable wear resistance, high strength/hardness, and strong diffusion resistance. The coating of HEAs on metallic substrates can be achieved through different techniques, including thermal spraying, laser deposition, and vapor deposition. HEAs have become a promising candidate for biomedical applications by combining tailor-made surface topography, excellent biocompatibility, appropriate surface chemistry, and element composition design. The present article is a thorough review of the research on the surface modification and coating of metallic biomaterials using HEAs. © 2022 The Authors

Design and successful synthesis of a series of novel luminescent silk chemically modified with europium(III) [Eu(III)] and europium(III)/terbium(III) [Eu(III)/Tb(III)] is reported. The modified silk specimens were characterised by infrared spectroscopy, fluorescence spectroscopy, scanning electron microscopy, and evaluated for their colour fastness. The rare earth ions were linked to the silk fibre via chemical bonds with the aid of tetracarboxylic acids used as the bridging ligands. Therefore, the modified silk had excellent luminescent stability and colour fastness to water and sunlight. Based on the blue fluorescence of silk along with the red and green luminescence of Eu(III) and Tb(III), respectively, under ultraviolet irradiation intelligent colour regulation was easily achieved by adjusting either the amount of Eu(III) or the ratio of Eu(III)/Tb(III). The Commission International de l'Eclairage chromaticity co-ordinates calculated from the emission spectra also confirm the colour changes. Benefiting from the tunable colour and high stability, the modified silk could be an excellent candidate for applications in anti-counterfeiting and flexible tunable light- emitting materials.

Metallic bismuth (Bi) has garnered significant attention in the field of photocatalytic nitrogen reduction owing to its remarkable nitrogen activation and hydrogen evolution inhibition. However, the effectiveness of Bi is still hindered by the electron transport obstruction caused by the Schottky junction between the semiconducting scaffolds. In this work, Bi metal nanoparticles were constructed on the surface of BiFeO 3 photocatalyst (Bi/BFO) by a simple in-situ precipitation method. The Bi nanoparticles prepared by this process not only provides sites for nitrogen adsorption/activation, but also facilitates the formation of a gradient doping of Fe 2 + produced by BFO during the precipitation process, effectively establishing an electronic tunnel at the interface of Bi and BFO. The improved Schottky junction with unidirectional electron transport provides sufficient electrons for nitrogen reduction at the Bi sites, and collaboratively enhances photocatalytic efficiency for nitrogen reduction. Consequently, the NH 3 yield of the optimized Bi/BFO reaches 202.5 μmol g − 1 h − 1 . This study presents an optimized approach for efficient implementation of Schottky junction in photocatalytic nitrogen reduction.

Prussian blue analogs (PBAs) are promising insertion-type cathode materials for different types of aqueous batteries, capable of accommodating metal or non-metal ions. However, their practical application is hindered by their susceptibility to dissolution, which leads to a shortened lifespan. Herein, we have revealed that the dissolution of PBAs primarily originates from the locally elevated pH of electrolytes, which is caused by the proton co-insertion during discharge. To address this issue, the water-locking strategy has been implemented, which interrupts the generation and Grotthuss diffusion of protons by breaking the well-connected hydrogen bonding network in aqueous electrolytes. As a result, the hybrid electrolyte enables the iron hexacyanoferrate to endure over 1000 cycles at a 1 C rate and supports a high-voltage pH-decoupled cell with an average voltage of 1.95 V. These findings provide insights for mitigating the dissolution of electrode materials, thereby enhancing the viability and performance of aqueous batteries.

Owing to its unique electronic configuration [Xe]4 f 0 , Ce 4+ -compound is a highly desired in the field of advanced nonlinear optical materials, yet its synthesis remains a great challange. Herein, we report a series of cerium fluorides, including a pure Ce 4+ -fluoride, high-performance Na 2 (Ce 4+ )F 6 ; three mixed valance state samples, (Mix1–3, with increasing Ce 3+ concentration); and a fully reduced pure Ce 3+ -fluoride Na 1.5 (Ce 3+ ) 1.5 F 6 . In particular, Na 2 (Ce 4+ )F 6 , shows an SHG response (4×KDP), and a wide band gap (4.77 eV), which are the strongest and widest among all Ce-containing materials to date. With systematic studies, we demonstrate that the subtle Ce 3+ impurity significantly reduces performance. By being aware of this fact and consciously controlling experimental conditions, we can ensure the synthesis of pure Na 2 (Ce 4+ )F 6 , which exhibits excellent overall performance and shows great potential for future applications. This work not only reinforced the crucial role of Ce 4+ in significantly enhancing the key performance, but also provided invaluable experimental evidence and theoretical support for the future design of more efficient and superior functional materials.
