Materials Science and Engineering R Reports, 2026
Two-dimensional metallic transition metal dichalcogenides offer high electrical conductivity and large surface areas for electrocatalysis, yet their inherent basal planes are catalytically inert. Here, we present an atomic-scale vacancy engineering strategy to activate the basal surfaces of metallic WSe 2 for reversible oxygen electrocatalysis. This approach, based on intentionally designed substitutional metal doping, promotes the spontaneous formation of selenium vacancies while preserving the metallic 1 T′ phase, thereby creating highly reactive and oxygen-affinitive sites. Density functional theory calculations reveal that these vacancy-mediated metal complexes dramatically lower the energy barriers for initial oxygen adsorption, enabling dissociative oxygen adsorption. Operando and ex-situ spectroscopic analyses confirm that vacancy-mediated metal complexes transform into dynamic Se/W-oxide intermediates under operating conditions. Se/W-oxides on the surface experimentally and theoretically prove electrocatalytic activity and reversibility. Applying this strategy in lithium–oxygen batteries, the basal-plane activated WSe 2 shows high discharge capacities (9868 mA h g −1 , corresponding to 3947 mA h g cathode − 1 ), impressive cycle retention over 550 cycles at 1000 mA h g −1 , and outstanding rate–capability over a wide current–density range (100–3000 mA g −1 ) during 256 cycles. - Toxicity of different light-emitting diode phosphor-dispersed encapsulants exposed by pharyngeal aspiration in mice

• The chemical composition of LED particles depended on the fluorescent color type. • Inhaled LED particles are persistent in the lungs and can migrate to other tissues. • Lithium ions may be closely involved in the formation of lamellar bodies. • Rod-shaped particles may be the main cause of collagen and collagen fibers. • Damaged mitochondria may contribute to the generation and growth of lamellar bodies. As the global use of light-emitting diodes (LEDs) expands, their waste management has become an increasingly important environmental issue. In the current study, potential health impacts associated with the inhalation of non-recycled LED components, particularly phosphor-dispersion encapsulation materials separated from waste LEDs, were identified. Si content was in the order of cool-white LED (CWL), natural white LED (NWL), and warm-white LED particles (WWL), and notable differences in rare-earth and alkaline-earth metals were observed between groups. When aspirated via the pharynx for 28 days (10 and 50 μg/mL), NWL and WWL significantly reduced triglyceride levels, and the three types of LED particles accumulated in lung tissue, affecting the distribution of elements in the heart, brain, and kidneys. Compared to the control group, the three types of LED particles increased the total number of pulmonary cells. They (50 µg/lung) also significantly increased pulmonary CXCL-1 and interferon-gamma levels, whereas the pulmonary macrophage chemoattractant protein-1 alpha level decreased significantly. Interestingly, the formation of lamellar bodies and tubular myelin was prominent in the lung tissues of CWL-treated mice, whereas collagen and collagen fibers were abundantly formed in the lungs of WWL-treated mice. Moreover, the lamellar body structures fused to damaged mitochondria or surrounding lamellar bodies, along with the loss of membrane integrity. Collectively, more intensive and effective recycling strategies for LED waste should be established to prevent potential adverse environmental and human health effects. Given that lamellar bodies and tubular myelin, which are potential initiators of pulmonary fibrosis, were found notably in CWL with the highest lithium content, and that lithium is a major raw material for secondary batteries, in-depth research on the relationship between inhaled lithium ions and pulmonary diseases should be conducted. - Recycling mining tailings into defect-engineered iron oxide for lithium-ion and lithium-oxygen batteries

A critical challenge hindering the practical application of lithium–oxygen batteries (LOBs) is the inevitable problems associated with liquid electrolytes, such as evaporation and safety problems. Our study addresses these problems by proposing a modified polyrotaxane (mPR)-based solid polymer electrolyte (SPE) design that simultaneously mitigates solvent-related problems and improves conductivity. mPR-SPE exhibits high ion conductivity (2.8 × 10−3 S cm−1 at 25 °C) through aligned ion conduction pathways and provides electrode protection ability through hydrophobic chain dispersion. Integrating this mPR-SPE into solid-state LOBs resulted in stable potentials over 300 cycles. In situ Raman spectroscopy reveals the presence of an LiO2 intermediate alongside Li2O2 during oxygen reactions. Ex situ X-ray diffraction confirm the ability of the SPE to hinder the permeation of oxygen and moisture, as demonstrated by the air permeability tests. The present study suggests that maintaining a low residual solvent while achieving high ionic conductivity is crucial for restricting the sub-reactions of solid-state LOBs. - Synthesis of ilmenite-derived TiO2 photocatalysts with different morphologies: Enhanced photocatalytic activity using ammonium hexafluorotitanate

Ceramics International, 2025 - Facile Solid-State Synthesis of Prelithiated LiTiO2 With Nitrogen-Doped Carbon for Lithium-Ion Battery Anodes

International Journal of Energy Research, 2025
Although Ti‐based oxides are attractive anode materials for Li‐ion batteries (LIBs) owing to their inherent stability and enhanced safety, their electrochemical performance is severely limited by low conductivity and slow Li‐ion diffusion. Conventional LiTiO 2 synthesis methods are not cost‐effective because they rely on high‐purity precursors and energy‐intensive procedures. To address these limitations, in this study, prelithiated LiTiO 2 with nitrogen‐doped carbon (NC–LiTiO 2 ) was synthesized via a solid‐state reaction using TiO 2 hollow spheres (HSs) derived from ammonium hexafluorotitanate (AHFT[(NH 4 ) 2 TiF 6 ]). The NC–LiTiO 2 exhibited a highly crystalline structure with a homogeneous elemental distribution, and the nitrogen‐doped carbon enhanced its electronic conductivity and facilitated Li‐ion diffusion, thereby improving the overall performance of the LiTiO 2 anodes. The electrochemical testing results indicated a high discharge capacity (170 mA h g –1 ), excellent rate performance, and good cycling stability over 1000 cycles at 2 C. The improved performance was attributed to the nitrogen‐doped carbon, robust structure, and progressive activation of Li‐ion pathways. Morphological and impedance analyses after cycling revealed minimal volume expansion and a significant reduction in the interfacial resistance. The strategy proposed herein offers a facile, cost‐effective route for fabricating prelithiated oxide anodes and is effective for enhancing their electrochemical performance through improved structural and interfacial design. - Enhanced visible-light photocatalytic activity of N-doped C/Na2Ti6O13/TiO2 hollow spheres for efficient dye degradation

Doping and hybridization with other semiconductors are highly effective ways to address the limitations, including their weak response to visible light and significant recombination of photogenerated carriers. In addition, the assisted carbon on the catalyst surface and the structural design have the advantage of being catalytically active. Herein, visible-light-active N-doped C/Na 2 Ti 6 O 13 /TiO 2 hollow spheres (denoted as N-C/NTO/TiO 2 HS) were successfully prepared using a facile two-step method and evaluated for methylene blue (MB) aqueous solution degradation under visible-light irradiation. The as-obtained N-C/NTO/TiO 2 HS demonstrated improved photocatalytic efficiency (94%) and pseudo-first-order kinetic degradation rate (0.023 min -1 ). Moreover, after three cycles of testing, N-C/NTO/TiO 2 HS showed a 91% degradation rate in its photostability. The enhanced photocatalytic performance was attributed to the combined effects of N-doping, carbon species on the surface, and the coupling of TiO 2 and Na 2 Ti 6 O 13 using morphology engineering. Finally, based on the experimental results, a possible photocatalytic mechanism was proposed. This study provides a rational approach toward the development of high-performance titanate-based photocatalysts for solar energy-assisted wastewater treatment. - Subchronic pulmonary toxicity of ambient particles containing cement production–related elements

Toxicology Reports, 2023
Chronic respiratory disease is among the most common non-communicable diseases, and particulate materials (PM) are a major risk factor. Meanwhile, evidence of the relationship between the physicochemical characteristics of PM and pulmonary toxicity mechanism is still limited. Here, we collected particles (CPM) from the air of a port city adjacent to a cement factory, and we found that the CPM contained various elements, including heavy metals (such as arsenic, thallium, barium, and zirconium) which are predicted to have originated from a cement plant adjacent to the sampling site. We also delivered the CPM intratracheally to mice for 13 weeks to investigate the pulmonary toxicity of inhaled CPM. CPM-induced chronic inflammatory lesions with an increased total number of cells in the lung of mice. Meanwhile, among inflammatory mediators measured in this study, levels of IL-1β, TNF-α, CXCL-1, and IFN-γ were elevated in the treated group compared with the controls. Considering that the alveolar macrophage (known as dust cell) is a professional phagocyte that is responsible for the clearance of PM from the respiratory surfaces, we also investigated cellular responses following exposure to CPM in MH-S cells, a mouse alveolar macrophage cell line. CPM inhibited cell proliferation and formed autophagosome-like vacuoles. Intracellular calcium accumulation and oxidative stress, and altered expression of pyrimidine metabolism- and olfactory transduction-related genes were observed in CPM-treated cells. More interestingly, type I-LC3B and full-length PARP proteins were not replenished in CPM-treated cells, and cell cycle changes, apoptotic and necrotic cell death, and caspase-3 cleavage were not significantly detected in cells exposed to CPM. Taken together, we conclude that dysfunction of alveolar macrophages may contribute to CPM-induced pulmonary inflammation. In addition, given the possible transformation of heart tissue observed in CPM-treated mice, we suggest that further study is needed to clarify the systemic pathological changes and the molecular mechanisms following chronic exposure to CPM. - Subway station dust-induced pulmonary inflammation may be due to the dysfunction of alveolar macrophages: Possible contribution of bound elements
