Sodium all-solid-state batteries (NaSSBs) with an alloy-type anode (e.g., Sn and Sb) offer superior capacity and energy density compared to hard carbon anode. However, the irreversible loss of Na+ at the alloy anode during the initial cycle results in diminished capacity and stability, impairing full-cell performance. This study presents an easy-to-implement cathode presodiation strategy by employing a Na-rich material to address these challenges. Leveraging the high theoretical capacity and suitable voltage window, Na2S is chosen as the Na donor, which is activated by creating a mixed electron-ion conducting network, delivering a high capacity of 511.7 mAh g−1. By adding a small amount (i.e., 3 wt.%) of Na2S to the cathode composite, a NaCrO2 || Sn full cell demonstrated capacity improvement from 90.8 to 118.2 mAh g−1 (based on cathode mass). The capacity-balanced full cell can thus cycle to more than 300 times with >90% capacity retention. This work provides a practical solution to enhance the full-cell performance and advance the transformation from half-cell to full-cell applications of NaSSBs. © 2025 Wiley-VCH GmbH.

The creation of advanced materials for addressing contemporary challenges in environmental monitoring and forensic investigations, as well as in food quality assessment, is very important in the modern technology research field. Hence, there is a high demand for multifunctional materials with innovative designs. In this study, a facile technique is used to synthesize Ni-doped BiVO4 (NBV) nanoparticles (NPs) using glucose as a reducing agent. The effect of doping and the structural transformation was studied by introducing different dopant percentages, such as 2%, 4%, 8%, and 10% Ni, into BiVO4 (BV) and comparing the characteristic properties of BV using characterization techniques such as XRD, UV–vis, FT-IR, SEM, PEIS, and PL. With the addition of dopant Ni, a phase transformation of BiVO4 occurs, retaining its original monoclinic phase while introducing another phase, such as tetragonal. This leads to the stabilization of a dual-phase system that alters the electrochemical and optical properties. The band gaps of the synthesized NPs are found to be in the range of 1.50–4.0 eV, with 4% Ni-doped BiVO4 (4 NBV) showing a very low band gap of 1.57 eV. 4 NBV modified GCE shows a highly sensitive response for the detection of vanillin, with a detection limit of 99 nM and a sensitivity of 81.21 A/M, highlighting its versatility in analytical applications. The photoluminescence property of NPs at 488 nm highlights their optical properties with greenish-blue emission for optoelectronic devices as well as advanced forensic studies through the development of visible, well-defined latent fingerprints. 4 NBV exhibits excellent photocatalytic properties, demonstrating 100% efficiency in degrading organic contaminants such as methylene blue.

Yet, achieving continuous, long-term, and in vivo monitoring remains challenging due to obstacles like device miniaturization, signal amplification, and sensor stability. To tackle these hurdles, researchers are leveraging nanostructured electrodes, leading to new EAB designs with improved in vivo biosensing performance. This opinion provides a brief overview of the development and latest progress in nanoconfined constructs for EAB in vivo biosensing. We illustrate fundamental sensing principles, the various nanostructures being explored, and their respective advantages. These nanostructured EABs hold promise for applications spanning disease diagnostics, environmental surveillance, and food safety management. Finally, we address the persistent challenges EABs face and discuss potential future directions, offering insights into how these sensors can continue to evolve and foster more effective healthcare technologies. © 2025 The Author(s)

Bioactive glasses and glass-ceramics have drawn significant attention due to their excellent bone-bonding capabilities and biocompatibility. This study investigates the effects of lithium fluoride (LiF) addition on the microstructure, mechanical properties, and biocompatibility of novel bioactive glass compositions. Glasses with varying LiF contents (1, 2, and 3 wt%) were synthesized using the melt-quenching method and subsequently heat-treated to obtain bioactive glass-ceramics. X-ray diffraction (XRD) analysis revealed an increase in the intensity of hydroxyapatite, fluorapatite, and diopside phases with increasing LiF content, suggesting enhanced crystallization. Vickers hardness measurements showed a significant improvement, with the highest hardness (730 MPa) observed in the K3 composition. Scanning Electron Microscopy (SEM) was used to examine the microstructural morphology, while Energy-Dispersive X-ray Spectroscopy (EDX) was employed to analyze the elemental composition of the samples. Furthermore, in vitro bioactivity assessments in simulated body fluid (SBF) confirmed the apatite-forming ability of all compositions. Cytotoxicity evaluations demonstrated enhanced cell viability in LiF-containing compositions, with K3 exhibiting the highest biocompatibility. The findings suggest that LiF addition optimizes crystallization, mechanical performance, and biocompatibility, making these modified bioactive glass-ceramics promising candidates for biomedical applications. © 2025

This study investigates the ureolysis and microbially induced calcium carbonate precipitation (MICP) characteristics of Sporosarcina pasteurii and Lysinibacillus sphaericus under varying incubation and reaction conditions. A series of batch MICP experiments were conducted to assess the effects of incubation duration and pH, bacterial cell density, and reagent (i.e., urea and calcium ion) concentrations on ureolysis and CaCO3 precipitation characteristics. The findings indicate that both bacteria exhibit higher urease activity after 24 hours of incubation compared to 48 hours, regardless of incubation pH. S. pasteurii exhibits maximum specific urease activity at an alkaline pH (pH 9.0), whereas L. sphaericus reaches peak activity at a neutral pH (pH 7.2). Across six incubation conditions for each bacterium, S. pasteurii exhibits greater sensitivity in specific urease activity, while L. sphaericus maintains a more consistent ureolysis performance. In terms of cell density, a lower OD600 (~0.1) enhances specific urease activity and early-stage mineralization efficiency, whereas a higher OD600 (~1.0) accelerates overall CaCO3 precipitation, enhances terminal-stage mineralization efficiency, and promotes the prolonged presence of vaterite. High reagent concentrations (1.0 and 1.5 M) enhance specific urease activity and CaCO3 precipitation rates and lead to over 93% of vaterite formation, while low reagent concentration (0.3 M) favors calcite-dominant precipitation over time. These findings provide insights into evaluating and optimizing MICP performance under varying incubation and reaction conditions. © 2025, The Authors. All rights reserved.

The thermal response of proximity Josephson junctions (JJs) is governed by the temperature (T)- dependent occupation of Andreev bound states (ABS), making them promising candidates for sensitive thermal detection. In this study, we systematically engineer ABS to enhance the thermal sensitivity of critical current (lc) of proximity JJs, quantified as |dlc/dT/| for threshold readout scheme and |dlc/***−1| for inductive readout scheme. Using a gate-tunable graphene-based JJ platform, we explore the impact of key parameters—including channel length, transparency, carrier density, and superconducting material—on the thermal response. Our results reveal that the proximity-induced superconducting gap plays a crucial role in optimizing thermal sensitivity. Notably, we see a maximum |dlc/***−1| value of 0.6 K−1 at low temperatures with titanium-based graphene JJs. By demonstrating a systematic approach to engineering ABS in proximity JJs, this work establishes a versatile framework for optimizing thermal sensors and advancing the study of ABS-mediated transport. © 2025, CC BY.

Magnetic topological materials LnSbTe (Ln = lanthanide) have attracted intensive attention because of the presence of interplay between magnetism, topological, and electron correlations depending on the choices of magnetic Ln elements. Varying Sb and Te composition is an efficient approach to control structural, magnetic, and electronic properties. Here, we report on the composition-dependent properties in PrSbxTe2−x. We identified the tetragonal-to-orthorhombic structure transitions in this material system and very large negative magnetoresistance in the x=0.3 composition, which might be ascribed to the coupling between magnetism and transport. Such unusual magnetotransport enables PrSbxTe2−x topological materials as a promising platform for device applications.

The second harmonic (SH) of an axicon generated Bessel-Gauss beam is created through the nonlinear interaction of photons with a crystal, resulting in the energy doubling of the output photons. In this work, we show experimentally that in addition to frequency doubling, the SH of Bessel-Gauss beams under asymmetric aberrations from an elliptic axicon exhibit intriguing beam formation. Particularly, the central region of the SH beam profile is composed of two central spots of various geometries surrounded by nested ellipses; one of which is the configuration of two central gamma dots with similar radius knotted by nested ellipses for a zeroth-order Bessel-Gauss pump. These SH beams consistently maintain their spatial profile throughout propagation, reminiscing the behavior of screw dislocations in wave patterns. Our numerical simulations produce beam dynamics consistent with that of experiments and further implicate the remarkable interweaving of bright spots with dark vortices. This is especially noticeable when the beams dynamically oscillate along the optical axis, resulting in the genesis of spatially polarized beams with a knotted framework. The insights gained from our study establish a novel paradigm for exploring interactions of Bessel-like beams with vortex dynamics. This, in turn, has the potential to spark innovations in optical applications, fostering new methodologies to harness and manipulate complex light structures. Our experimental findings could spur new methods of generating logical states of light and new opportunities for material processing control.
