This review systematically explores the pivotal role of wettability in the crystallization of REBa2Cu3O7-x (REBCO) superconductors, highlighting its impact on crystal growth, structural quality, and superconducting performance. The discussion involves three fabrication methods: Top-Seeded Solution Growth (TSSG), Traveling-Solvent Floating-Zone (TSFZ), and Top-Seeded Melt Growth (TSMG). Conventional Y2O3 crucibles lead to severe Ba–Cu–O liquid loss, while modified crucibles, such as Fe–Y2O3 and Ca–ZrO2 reduce wettability, allowing stable growth of large, doped crystals. In TSFZ processes, modified precursor rods (Y2O3+Ba2Cu3Oy) with low wettability effectively suppress liquid migration and stabilize the molten zone, facilitating Y123 crystal growth. For TSMG approach, the thermal stability of REBCO film seeds correlates with melt wettability, with compositional modifications such as Ba-rich melts or buffer layers optimizing interfacial energy to enhance seed performance. These insights into tailored wettability provide practical guidelines for optimizing REBCO crystals and offer transferable principles for other advanced materials.

The evolving need for eco-friendly and efficient energy storage devices has prompted the exploration of sustainable electrode materials. Biomass-derived porous carbon stands out from traditional carbon materials due to its supercapacitor application advantages, which include natural availability, cost-effectiveness, low carbon superstructure porosity, easy structural modification, and heteroatom content. This review focuses on synthesis and structural performance of biomass-derived porous carbon electrodes, while also highlighting their electrochemical functionality and practical challenges. Recent research shows significant electrochemical performance, including specific capacitance over 300F/g, energy density of 60 Wh/kg in asymmetric configurations, and sustained cycling stability (greater than 90 % after 10,000 cycles). These advances have been offset by critical obstacles including feedstock inconsistency, environmental challenges from chemical activation, limited scalability, lack of measurement standards, and performance benchmarks. This review describes such gaps in detail and proposes green material synthesis, eco-friendly machine learning design, and lifecycle sustainability furthering material performance as primary focal points.

The integration of graphene with diamond holds great promise for all-carbon materials, yet the precise mechanism governing graphene formation on diamond has remained unclear due to the lack of direct experimental evidence. Conventional preparation methods often rely on empirical annealing parameters. In this study, the catalytic transformation from diamond into graphene or graphite (nickel (Ni) as a catalyst) is investigated through in-situ heating transmission electron microscopy (TEM). We demonstrate that the transition proceeds via a metal-induced solid-state mechanism that is driven by Ni catalysis and reaction-diffusion between Ni and carbon (C) atoms at elevated temperatures. Key processes include Ni grain migration and C–Ni interdiffusion. The annealing duration significantly influences the location and number of graphene layers. Notably, prolonged annealing causes the development of graphene on the Ni surface, whereas rapid, short-term annealing results in the formation of graphene at the diamond/Ni interface. Extended high-temperature exposure increases the number of graphene layers, potentially facilitating graphite formation. Ab initio simulations reveal the polymerization pathway of carbon within the Ni(C) solid solution during graphene nucleation. These insights provide valuable guidance for designing application-specific graphene-on-diamond (GOD) structures, promoting the development of advanced carbon-based technologies.

Eu3+-activated red-emitting phosphors are of sustained interest for multifunctional applications. However, their poor stability under harsh conditions, such as high temperatures and aqueous environments, critically limits their advancement in lighting and optical security technologies. Herein, the molybdenum tellurate Ca3(TeO3)2(MoO4) (CTMO) is activated by Eu3+ for the first time, realizing bright red emission with high stability. In parallel, to reduce defect-induced non-radiative transitions due to the non-equivalent substitution of Eu3+ for Ca2+, the enhancement of co-doping alkali metal (A+ = Li+, Na+, K+) on the red luminescence is demonstrated thoroughly. The incorporation of the co-dopant Na+ delivers a 3-fold enhancement in emission intensity, along with a 1.56-fold increase in quantum efficiency. Besides, the optimized CTMO:Eu3+,Na+ powder exhibits improved luminescence stability at high temperature. When incorporated into a white-lighting device, warm white light with low correlated color temperature (CCT = 3775 K) is achieved. Meanwhile, the security ink is prepared by dispersing the resulting powder into polydimethylsiloxane (PDMS) matrix, enabling screen printing, coating, and handwriting to create security patterns on various substrates (woven/non-woven fabrics, paper, glass, and plastic sheets). The ink retains bright luminescence after immersion in water for 40 days. This investigation significantly boosts the multifunctional applicability of Eu3+-activated red-emitting phosphors for lighting and long-lasting optical security.

In the orthorhombic system, starting from inserting carbon into ultra-dense/ultrahard/metastable/metallic novel C6 with distorted C4 tetrahedra, a dense/superhard/stable/insulating C8, with regular C4 tetrahedra was found and characterized with properties close to Diamond. Such C6→ C8 transformation was then inscribed within an original protocol establishing systematics in “C4+2m” 3D stoichiometries in relation with Diamond, featuring regular tetrahedra/versus distorted tetrahedra allotropes, where m is an odd or even integer. Odd m values lead to superdense, ultrahard, metastable C6, C10, C14 whereas m even values give superhard Diamond-like stable C4, C8, C12. The obtained dia-C4, sql-C6, dia-C8, 42T1164-HZ C10, dia-C12 sequence alternates from one type to the other with increasing amounts of carbon. Such findings are proposed as a holistic vision of carbon allotropes characterized by exceptional mechanical and electronic properties.

The increasing demand for high-performance energy storage has intensified the pursuit of alternatives to conventional lithium-ion batteries. Lithium-sulfur (Li–S) batteries has been extensively used due to their high theoretical energy density (2600 Wh kg−1), low cost, and sulfur's environmental benefits. However, traditional Li–S systems face challenges including polysulfide shuttle effects, lithium dendrite formation, and limited cycle life. Incorporating solid-state electrolytes (SSEs) have enhanced the safety and stability by replacing flammable liquids. Recent progress in solid-state Li–S (SSLS) batteries includes development of high-conductivity SSEs (sulfide, halide, polymer-ceramic composites), electrodes provided with the volume changes and minimize interfacial resistance, and improved cathode architectures for optimized ion/electron transport. This review comprehensively analyzes the development in solid-state lithium-sulfur (SSLS) batteries over the past decade. SSLS development is driven by the potential for higher energy density and enhanced safety that have been essential for next-generation energy storage.This review also focuses on solid electrolytes as the key enabler for solid-state lithium-sulfur (SSLS) battery performance, addressing the challenges associated with liquid electrolytes such as flammability, polysulfide shuttle, and lithium dendrite formation. Finally, the review highlights the importance of integrated cell design, where optimized electrode architectures and advanced solid electrolytes work synergistically to maximize performance..

High-entropy polyelement nanoparticles (HEPNs) exhibit unique behaviors distinct from those of the solid phases of individual elements. The disordered nature of multielement compounds introduces structural complexity and unprecedented compositional variations, necessitating a comprehensive understanding of stabilization enthalpy, entropy, and property optimization. HEPNs are particularly desirable when fabrication methods provide precise control comparable to that achieved conventional alloy design. Recent advancements in fabrication techniques have enabled greater control over the inherently disordered structures of HEPNs. This study explores emerging strategies for synthesizing HEPNs with tunable compositions, tailored atomic configurations, and enhanced catalytic activity achieved through the formation of novel active catalytic sites. It discusses fabrication pathways for different types of HEPNs, their stabilization mechanisms, and catalytic performance, providing insights into how of various synthesis approaches influence these properties. Collectively, these strategies enable the rational design and predictable controlled modulation of catalytic activity and atomic order within the disordered lattice, establishing a basis for enhanced applications.

Presently Fe3+-doped NIR phosphors exhibit immense potential for multiple applications. However, a more comprehensive understanding of Fe3+ site-occupancy and luminescent mechanism is urgently needed for enhancing material design and synthesis. In this work, a high-efficient NIR-I emitting Fe3+-doped NaAl11O17 phosphor was synthesized and systematically studied. A hybrid density functional theory (DFT) calculation was performed on geometric and electronic structures to study Fe3+ occupation preference and the corresponding optical properties. It is found that Fe3+ prefers to occupy AlO4 sites with lower total energy compared with AlO6 sites. Under 340 nm excitation, NaAl11O17: Fe3+ phosphors exhibited a high-efficient NIR emission of 600∼1000 nm peaking at ∼770 nm, with a high internal quantum efficiency of 78.12 %. Based on both theoretical and experimental results, the 3d energy-level diagram of Fe3+ in NaAl11O17 is constructed and discussed with crystal field strength analysis. The optimal NaAl11O17: Fe3+ phosphor shows good thermal stability while keeping 87 and 45 % of room-temperature intensity at 373 and 473 K. A NIR pc-LED was fabricated and demonstrates applications in nondestructive detection and angiography. This hybrid investigation on Fe3+-doped NaAl11O17 NIR-I phosphor could provide an insight for developing Fe3+-activated NIR luminescent materials with excellent performance and expanding their application prospects.

A hybrid density functional theory (DFT) calculation was performed on geometric and electronic structures to study Fe<sup>3+</sup> occupation preference and the corresponding optical properties. It is found that Fe<sup>3+</sup> prefers to occupy AlO<sub>4</sub> sites with lower total energy compared with AlO<sub>6</sub> sites. Under 340 nm excitation, NaAl<sub>11</sub>O<sub>17</sub>: Fe<sup>3+</sup> phosphors exhibited a high-efficient NIR emission of 600∼1000 nm peaking at ∼770 nm, with a high internal quantum efficiency of 78.12 %. Based on both theoretical and experimental results, the 3<em>d</em> energy-level diagram of Fe<sup>3+</sup> in NaAl<sub>11</sub>O<sub>17</sub> is constructed and discussed with crystal field strength analysis. The optimal NaAl<sub>11</sub>O<sub>17</sub>: Fe<sup>3+</sup> phosphor shows good thermal stability while keeping 87 and 45 % of room-temperature intensity at 373 and 473 K. A NIR pc-LED was fabricated and demonstrates applications in nondestructive detection and angiography. This hybrid investigation on Fe<sup>3+</sup>-doped NaAl<sub>11</sub>O<sub>17</sub> NIR-I phosphor could provide an insight for developing Fe<sup>3+</sup>-activated NIR luminescent materials with excellent performance and expanding their application prospects.</div></div>","PeriodicalId":415,"journal":{"name":"Progress in Solid State Chemistry","volume":"80 ","pages":"Article 100551"},"PeriodicalIF":10.5,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145614851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This original work investigates the high-pressure behavior of BiF3 polymorphs, with emphasis on the stereochemical activity and spatial localization of the 6s2 lone electron pair (E) of Bi3+and the 2 s2 Es of fluoride anions. Using density functional theory (DFT) and electron localization function (ELF) analyses, we characterize the evolution of α-, β-, and γ-BiF3E polymorphs and report two novel high-pressure phases, δ-BiF3E and κ-BiF3E, stabilized at approximately 70 GPa and above 200 GPa, respectively. The β-phase undergoes a clear phase transition near 70 GPa, where structural gliding of fluorine layers induces a symmetry shift from Pnma to Cmcm space group, corresponding to the δ-BiF3E phase. The δ-phase features a base-centered orthorhombic framework with perichoretic localization of the Bi 6s2 lone pair in multiple spatial positions. At pressures exceeding 200 GPa, a previously unobserved polymorph, κ-BiF3E, emerges with a penta-capped triangular antiprismatic coordination environment and a distorted screw-axis symmetry.
In this paper “perichoresis” is introduced as an original conceptual tool to describe the simultaneous localization of lone pairs in multiple spatial domains without invoking electronic delocalization.
The results provide insight into the high-pressure stereochemistry of heavy p-block compounds and offer a predictive model for lone pair behavior under compression.
