The construction of lunar stations for research and living requires high-performance building materials that can adapt the harsh lunar environment. One of feasible building materials is fiber-reinforced composites, for which the composition of glass fibers can be designed like lunar soils, i.e., terrestrial basalt and in turn, the "lunar glass" can be drawn into fibers. Because of a wide variation of TiO2 in lunar soils, our study focused on a series investigation on the effect of TiO2 (0.55 wt% - 6.14 wt%) on fiber spinnability and strength of the simulated "lunar glass and glass fibers". The baseline glass composition was derived from a simulated TiO2-lean lunar soil and other glasses were made at different TiO2 doping levels. The addition of TiO2 was found to reduce the melt thermal stability, there appears a TiO2 threshold (6.14 wt%), at which fibers cannot be drawn without breakage because of melt devitrification. The fiber tensile strength exhibits a nonlinear characteristic with an apparent maximum at 1.52 wt% TiO2. FTIR and Raman spectroscopic studies were carried out to investigate the glass network structure responses to TiO2 modifications and show TiO2 functions as a network modifier, depolymerizing the silicate network. Statistical structure (FTIR & Raman based)–property modeling was attempted to further elucidate the effect of TiO2-induced structure change on Tg and fiber tensile strength. Good agreements were found between the model predictions and the measured values. © 2023, The Authors. All rights reserved.

Inorganic CsPbI3 perovskite solar cells (PSCs), with outstanding thermal stability and appropriate optical band gap, are regarded as promising candidates for efficient single solar cells and the top sub-cell in tandem solar cells. Nevertheless, the substantial internal defect recombination and stringent preparation process conditions impede its further advancement. To obtain stable β-CsPbI3 film under open-air conditions, 1,4-phenyldimethylamine iodine (PhDMAI2) is selected as additive for the first time to prevent water erosion and regulate the intermediate phase transition during annealing. The systematic experimental results reveal that PhDMAI2 can accelerate the rate of intermediate phase conversion to β-CsPbI3 and build better energy level structure between perovskites (PVK) and hole transport layer (HTL), which effectively diminishes the quantity of pinholes and enhances the transportation and extraction of charge carriers at the interface. To further expand the application field in tandem or flexible devices, RbCl-doped SnO2 is adopted to replace the commonly used high temperature TiO2 as the electron transport layer (ETL), which not only enhances the electron transport capacity but also reduces the manufacturing temperature to below 200 ℃. Finally, the CsPbI3 PSCs with a PCE of 18.54% was achieved via a doping solvent engineering, which is one of the highest PCE values of SnO2 based CsPbI3 PSCs fabricated in ambient air. © 2025, The Authors.

Biphasic or multiphase heterostructures hold attractive prospects in engineering advanced electrode materials for energy-related applications owing to the appealing synergistic effect;however, they still suffer from unsatisfied electrochemical activity and reaction kinetics. Herein, guided by density functional theory calculation, a well-engineered selenides heterostructure with high-density biphasic interfaces of Ni3Se4-NiSe2 fastened in N, O-codoped carbon matrix was developed for high-performance lithium storage and electrocatalysis. By controlled selenylation of metal-organic framework (MOF), a series of NiSex@C hybrids (Ni3Se4@C, Ni3Se4/NiSe2@C-1, Ni3Se4/NiSe2@C-2, and NiSe2@C) with tunable biphasic components and grain sizes were prepared. Abundant two-phase interfaces with higher interface density are generated inside the Ni3Se4/NiSe2-1 induced by much smaller nanograins in comparison with the Ni3Se4/NiSe2-2, so that significant charge redistribution and faster electrons/Li+ ions transfer kinetics are achieved within the selenides, which are proved by the mutual verification of experiment performance and theoretical analysis. Benefitting from the optimized heterointerfaces, the Ni3Se4/NiSe2@C-1 manifests reduced electrode polarization, superior rate capability, and prolonged cyclic stability (621.3 mAh g-1 at 1 A g-1 for 1000 cycles;362.3 mAh g-1 at 4 A g-1 for 2000 cycles) with respect to the Ni3Se4/NiSe2@C-2, as well as excellent performance in LiCoO2//Ni3Se4/NiSe2@C-1 full cell. Detailed electrochemical analysis confirmed rapid e-/Li+ diffusion rate，reaction mechanism and more pseudocapacitive energy for the Ni3Se4/NiSe2@C-1. Therefore, the Ni3Se4/NiSe2@C-1 showcases superior hydrogen evolution reaction (HER) and lithium storage performances. This work demonstrates the significance of interface modulation of multiphase heterostructures to boost the electrochemical performance in energy storage and conversion. © 2022, The Authors.

Indentation has been widely used for investigating the mechanical behavior of glasses. However, how the various microscopic properties (such as atomic structure and mechanics) of glass evolve from the immediate contact with the indenter to the far-field regions, and how these observables are correlated to each other remain largely unknown. Here, using large-scale molecular dynamics simulations, we investigate the response of a prototypical sodium silicate glass under shape contact load up to an indentation depth of 25 nm. Both the short- and intermediate-range structures are found to exhibit notable changes below the indent, indicating that indentation deformation induces a more disordered and heterogeneous network structure. In addition, we find that the indentation-induced changes of local properties all exhibit an exponential decaying behavior with increasing distance from the indent. Comparison of the characteristic decay lengths of these local properties indicates that the structural origins of shear flow and densification are the changes of the network modifier's coordination environment and the inter-tetrahedral connection, respectively. The decay of densification is considerably slower than that of shear strain, implying that the former might contribute more to the deformation at the far-field regions. Our findings not only contribute to an atomistic understanding of the indentation response of silicate glasses but also pave the way towards rational design of damage-resistant glassy materials. © 2023, CC BY.

Antiferroelectrics exhibit unique double-hysteresis polarization loops, which have garnered significant attention due to their potential applications such as energy storage, electromechanical transduction, as well as synapse devices. However, numerous antiferroelectric materials have been reported to display signs of hysteresis loops resembling those of ferroelectric materials, and a comprehensive understanding remains elusive. In this work, we provide a phenomenological model that reproduces such widely observed artificial ferroelectric hysteresis with a superposition of numerous disordered antiferroelectric loops that have varying antiferroelectric-to-ferroelectric transition fields, particularly when these field ranges intersect. Experimentally, we realized such artificial ferroelectric-like hysteresis loops in the prototypical antiferroelectric PbZrO3 and PbHfO3 thin films, by introducing non-uniform local disorder (e.g., defects) via fine-tuning of the film growth condition. These ferroelectric-like states are capable of persisting for several hours prior to transitioning back into the thermodynamically stable antiferroelectric ground state. Those results provide insights into the fundamental impact of disorder on the AFE properties and new possibilities of disorder-tailored functions. © 2025 Acta Materialia Inc.

Poly (ionic liquid) (PIL) has emerged as a promising polymer substrate for solid electrolytes in lithium metal batteries due to its high ionic selectivity, excellent thermal stability, and compatibility with in situ polymerization processes. However, the limited ionic conductivity of PIL, primarily attributed to its restricted free volume and rigid polymer segments at room temperature, poses a significant challenge to its broader application on solid-state batteries. Herein, poly(1,3-dioxolane) (PDOL) is incorporated into PIL as a high-ionic-conductivity component to fabricate a semi-interpenetrating double network quasi-solid electrolyte (SIDN-QSE). The introduction of PDOL soft chains markedly improves the ionic conductivity of PIL-based quasi-solid electrolytes while preserving the advantageous properties of PIL, including its mechanical strength and thermal stability. Furthermore, the precursor containing ionic liquid with high dielectric constant induces the formation of the anions gathering inner Helmholtz plane (IHP) nearing the surface of the cathode, followed by the construction of the artificial cathode interface through the pre-reduction process. As a result, LiFeO4|SIDN-QSE|Li batteries achieve a high capacity retention of 70.4% after 700 cycles at 2 C and 30°C. Additionally, pouch cells incorporating the SIDN-QSE demonstrate excellent safety performance, withstanding mechanical stress tests such as bending, cutting, and piercing without compromising functionality. © 2025, The Authors.

High density Gd2O3–GdF3–Al2O3–B2O3–SiO2–CeF3 (GFOx) glass scintillators with different dimensions were synthesized. The glasses have a ∼75 % transmittance in visible range with a cut off wavelength of 373 nm. With the dimension increases, the energy transfer efficiency of GFOx glasses decreases from 77.0 % to 28.3 %. And the photoluminescence quantum yield (PL QY) of all glasses exceeds 56 % with a maximum of 68.4 %. GFOx glass scintillators exhibit a X–ray excitation luminescence (XEL) spectrum in 300–600 nm, and the XEL intensity decreases with increasing dimension. Under γ–ray excitation, a scattering model was established based on the light yield and aspect ratio of the glasses. The accuracy of the model was verified by measurement of commercial BGO crystal. In GFOx glass scintillator system, the intrinsic light yield of at 10 mm thickness is 1318 ph/MeV, while light loss coefficient is −0.12. With the aspect ratio increases, the formation and transport efficiency of excitons improve due to a larger surface area and more interfaces, resulting in a faster rise time. Meanwhile, all glasses exhibit a double exponential decay, including a fast component (∼100 ns) and a slow component (∼520 ns), and shows same trend as the rise time. In addition, the photon collection efficiency of SiPM coupled with the glasses decreased from 96.2 % to 31.8 %. Because the scattered photons can hardly reach the SiPM due to poor actual light attenuation length. © 2025

Fibrous electronics are essential components of wearable human-machine interfaces. However, the mass production and application of fibrous electronics will inevitably lead to electronic waste problems. Therefore, recyclability has become a basic required feature of fibrous electronics for future use. Here, we realize an intrinsically all-recyclable, ultra-stretchable and scalable resistive sensing ﬁber based on liquid metal and thermoplastic materials. Given the ultra-stable electrical properties of the sensing fiber (~10,000 cycles remain stable and regular) and the ability to continuously capture real-time static and dynamic somatosensory signals, we design a wireless smart glove-based interactive interfaces with cost-effectiveness, high integration, self-adaptability and crosstalk-free recognition ability of both static and dynamic hand gestures. Combined with machine learning technology, the successful construction of three static and dynamic hand gesture recognition systems (11 hand gestures with a recognition accuracy of ~93.6%) demonstrates the potential of the proposed wireless smart gloves to have widespread practical applications prospects. © 2022, The Authors.
