NaCrO 2 is an indispensable compound in the separation of vanadium from chromium in high-chromium vanadium slag, highlighting the need for comprehensive thermodynamic data for this compound. In this study, a high-purity NaCrO 2 compound was synthesized by solid-state sintering. Using density functional theory (DFT) combined with experimental measurements, the lattice dynamics and thermodynamic properties of NaCrO 2 were comprehensively investigated. The phonon structure was computed using first-principles methods, and the absence of imaginary frequencies was observed, demonstrating its dynamic stability. The low-temperature heat capacity of NaCrO 2 was measured using a physical properties measurement system (PPMS). Separation of the experimental heat capacity into lattice and magnetic contributions yields a magnetic entropy of 11.30 J K −1 mol −1 , which agrees well with the theoretical spin‑only entropy of Cr 3+ ( R ln4 = 11.53 J K −1 mol −1 ). The entropy at 298.15 K is derived as 78.25 ± 0.2 J K −1 mol −1 . The DFT-calculated thermodynamic properties show good agreement with the experimental results, confirming the reliability of the computational approach. This study provides critical thermodynamic property for the NaCrO 2 in the Na 2 O–Cr 2 O 3 system, thereby directly supplementing the fundamental thermodynamic database required for the optimization of high-efficiency vanadium–chromium separation processes.

A bilayer Cu-BTC@Zn interlayer was in-situ grown on Zn anode via exchange reaction. • The upper layer, rich in carboxyl, promotes the ordered deposition of zinc ions. • The bottom layer of zincophilic Cu clusters forms dense physical protection. • Cu-BTC@Zn symmetric cell cycles over 4000 h at 3 mA cm −2 and 2000 h at 10 mA cm −2 . Aqueous zinc-ion batteries face severe challenges in practical cycling, mainly including irregular zinc dendrite growth and unstable interfacial reactions, which greatly degrade the cycling performance. Herein, via a facile immersion method relying on a one-step in-situ spontaneous displacement reaction, an organic-inorganic composite layer composed of organic components and copper nanoparticles are fabricated on the surface of the zinc metal anode. The upper layer is enriched with carboxyl groups and Cu 2+ , constructing the upper layer by coordination interactions. Acting as migration sites and transport pathways for Zn 2+ , the as-formed SEI layer induces the uniform and ordered deposition of zinc. The bottom layer is composed of zincophilic copper clusters, which can form a compact physical shielding layer on the zinc anode surface and effectively inhibit interfacial corrosion. Benefiting from the synergistic effect, the symmetric cell achieves an ultra-long cycle life of over 4000 h at 3 mA cm −2 , and still maintains a cycle life exceeding 2000 h even at a high current density of 10 mA cm −2 . Meanwhile, the Cu-BTC@Zn//MVO full battery exhibits a 57% increase in capacity retention compared with bare Zn anode after 700 cycles. Meanwhile, this work reveals the synergistic regulation mechanism of the organic-inorganic composite layer toward Zn deposition, and provides a facile and practical strategy to construct stable artificial SEI layers for high performance zinc-metal anodes. The organic copper composite interface layers with a unique bilayer structure, fabricated on the zinc anode surface via a one-step in-situ spontaneous displacement reaction. The bilayer structured SEI facilitates orderly zinc ion deposition and inhibits zinc dendrite growth. This approach offers a novel strategy for designing highly stable and durable anodes for aqueous zinc-ion batteries. Download: Download high-res image (91KB) Download: Download full-size image

Additive engineering has propelled lab-scale perovskite solar cell efficiencies exceeding 27%, yet translating these achievements to industrial manufacturing requires multifunctional additives that simultaneously optimize crystallization, passivate defects, enhance mechanical robustness, and maintain compatibility with high-throughput coating processes. Here, we introduce glutaramide (GTA) as an all-in-one bridging coordination additive that addresses these challenges. Density functional theory calculations reveal that GTA forms a thermodynamically favored bidentate bridging coordination between adjacent [PbI 6 ] 4− octahedra. This unique configuration retards crystallization kinetics during annealing, yielding micron-scale grains with reduced defect density. Upon annealing, GTA spontaneously migrates to the film surface, where it passivates undercoordinated Pb 2+ and halide ions, toughens perovskite lattice, relieves residual stress, and increases hydrophobicity. Crucially, GTA enhances ink wettability, enabling pinhole-free, blade-coated large-area films. Small-area rigid and flexible cells achieve champion efficiencies of 26.65% and 25.22%, respectively. Remarkably, blade-coated 22.95 cm 2 modules deliver efficiencies of 24.61% (rigid) and 22.57% (flexible), retaining up to 99.6% of small-area performance. Encapsulated target devices achieve a T 90 lifetime of 1020 h under continuous 1-sun tracking, nearly doubling the control (520 h), while flexible devices demonstrate superior bending endurance. This work establishes that a single bridging additive can synergistically balance efficiency, stability, and scalability for commercial perovskite photovoltaics.

Repair of craniofacial bone defects remains highly challenging due to the region's complex anatomy close to vital brain marrow tissue. How to make a safe and efficient repair without disturbing surrounding tissues is critical, especially in external-stimulus-enhanced regeneration strategy. Magnetic hyperthermia therapy (MHT), due to its ability of uniform heat generation and good penetration, has gained increasing attention in bone repair. An asymmetric magnetic microspheres hybrid hydrogel was developed with magnetothermal responsiveness for targeted heating at the defect, preventing the risk of potential thermal injury to adjacent critical tissues. Guided by an external magnetic field, magnetic microspheres distributed in the upper side of the hydrogel achieved localized mild heating (40°C–42°C) under an alternating magnetic field (AMF), whereas the lower side remained within a physiologically safe temperature (< 38°C). In vitro and in vivo experiments showed that the asymmetric magnetic hydrogel under safe magnetothermal stimulation significantly enhanced the osteogenic differentiation and vascularization. Furthermore, transcriptomic analysis and histological staining suggested that this platform may convert external magnetothermal stimulation into intracellular signals by activating the PI3K-Akt pathway and upregulating key osteogenic and angiogenic markers. Overall, this asymmetric magnetothermal hydrogel offers a spatially controlled, safe, and effective strategy for bone regeneration.

The clinical success of chimeric antigen receptor (CAR) T cell therapy requires scalable, non-invasive strategies for in vivo T cell engineering. Although mRNA delivery offers a promising alternative, lipid-nanoparticle-based carriers show limited efficiency for in vivo T cell transfection and typically require antibody conjugation. Here we report an inherent T cell-activating polymer–lipid nanoparticle that enables ligand-free, efficient mRNA transfection and activation of T cells in vivo. This mRNA delivery vehicle, composed of p -toluenesulfonyl arginine (RT)-modified oligoethylenimine-based lipid nanoparticles (ERTLNPs), preferentially mediated mRNA transfection in the spleen following systemic administration. Without exogenous stimulation, ERTLNPs intrinsically activated T cells, triggering robust mRNA expression and proliferation. Mechanistically, ERTLNPs engaged the PI3K/AKT/mTOR signalling axis to reprogram T cell metabolism, promoting expansion and restraining exhaustion. The systemic delivery of mRNA encoding fibroblast activation protein CAR via ERTLNPs contributed to the in situ generation of functional CAR T cells, which efficiently eliminated pathological fibroblasts in models of cancer and fibrosis, with minimal off-target effects. This ligand-free, metabolically reprogramming mRNA delivery system provides a clinically translatable approach for in vivo CAR T cell generation.

Translating advanced luminescent materials into field-deployable screening tools remains a core challenge, demanding synergy between advanced optical materials and device engineering. Here, we demonstrate a portable dual-mode near-infrared semi-quantitative screening device. the luminescence performance of the core emitting materials, specifically lead-free Nd³⁺/Yb³⁺ co-doped Cs₂NaYCl₆ double perovskite phosphors, was first optimized through a machine-learning (ML) guided approach. Subsequently, these optimized phosphors were integrated to enable the device. Specifically, the Nd³⁺-doped emitter targets the 885 nm characteristic absorption band of alcohol while exhibiting anomalous thermal quenching, whereas the Nd³⁺/Yb³⁺ variant leverages 78.66% energy transfer efficiency to yield stable 985 nm emission (70% retention at 500 K) matching the characteristic absorption band of water. These optimized phosphor-converted LEDs were integrated into a compact detector featuring a coaxial dual-disc stepper mechanism and a customized three-stage circuit that amplifies faint optical signals into a five-level visual indicator. This configuration enables rapid screening of alcohol (30–60%) and water content (45–100%). Validated on commercial samples, this work establishes a holistic platform bridging high-precision instrumentation and real-world portability.

Garnet-type Li7La3Zr2O12 (LLZO) stands out as one of the most promising ceramic materials for solid-state lithium-ion batteries (LIBs), owing to its high ionic conductivity and electrochemical stability. However, critical challenges such as high interfacial resistance and poor cycling performance, particularly at subzero temperatures, have hindered its widespread application. Herein, we propose a composite solid electrolyte design by dispersing Eu-doped Li7+xLa3Zr2-xEuxO12 as an inorganic filler into a gel polymer matrix based on poly-1,3-dioxolane. This inorganic-polymer hybrid structure significantly enhances the low-temperature performance of LIBs. The incorporation of the gel polymer not only improves the interfacial contact between LLZO and the electrodes but also provides multiple pathways for lithium-ion transport, leading to enhanced ionic conductivity with the value of 5.6 × 10–4 S cm–1 at 20 °C and 9.34 × 10–5 S cm–1 at −20 °C. Electrochemical evaluations demonstrate that the LLZEO/PDL composite electrolyte exhibits remarkable performance at −20 °C: Li|Li symmetric cells achieve stable cycling for over 2000 h at 0.1 mA cm–2, and Li|LiFePO4 full cells deliver a high reversible capacity of 71.8 mAh g–1 at 0.1C, with a capacity retention of 68.8% after 300 cycles.

Hard carbon (HC) anode based solid-state sodium-ion batteries (SSIBs) possess highly intrinsic safety and cost effectiveness in the application of large-scale energy storage. However, it is hindered by large interfacial impedance and sluggish Na+ transport kinetics from the solid–solid electrode contact. Here, we propose an electrochemical presodiation strategy to in situ form a thin, uniform, and inorganic-rich (NaF/Na2O) solid-electrolyte interphase (SEI) on the HC anode. Such an SEI layer provides stable and good contact, leading to markedly reduced charge-transfer resistance and robust Na+ transport in a polymer-based solid electrolyte. The evidence for reversible Na+ insertion/extraction in the HC anode for SSIBs was first revealed by in situ X-ray diffraction. Consequently, the presodiated HC-based half-cell exhibits a reversible capacity of 275.2 mAh·g–1 and good cycling stability with 90.9% retention after 100 cycles at 0.1 C. Finally, the presodiated HC-based SSIBs were constructed with the Na3V2(PO4)3 cathode, delivering a high capacity of 106.9 mAh·g–1 at 0.1 C and good cycling stability without external pressure. These findings highlight inorganic engineering of the SEI as a powerful strategy for boosting interfacial kinetics toward regular pressure HC anode-based SSIBs.

The integration of multimodal sensors, energy harvesting, and storage modules facilitates the advancement of intelligent wearable electronic products. However, existing modular construction strategies have low integration levels, leading to cumbersome devices that may compromise the stability and reliability of signal acquisition. Here, we propose an all-in-one design strategy by integrating the three modules into a single polymer substrate prepared via laser-induced graphene technology to construct a fully integrated self-powered multimodal sensing system. This sensing system consists of bioenergy harvesting modules (lactate biofuel cells), flexible energy storage modules (Zn/MnO2 batteries), and multifunctional sensing modules (glucose, ascorbic acid, electrocardiogram, and electromyography). As a proof-of-concept application, the self-powered system is demonstrated to be worn on various parts of the human body for the real-time monitoring of health.

In gout progression, uric acid (UA) accumulation triggers crystal deposition, while interleukin-6 (IL-6) drives the subsequent inflammatory flares. Therefore, monitoring both UA and IL-6 is important for gout management. In this study, for the first time a microfluidic electrochemical system (MES) has been developed to simultaneously detect UA and IL-6 levels in blood. The MES consists of a multilayer microfluidic chip that incorporates a plasma separation module and two screen-printed electrochemical (SPE) sensors, integrated with a wireless potentiostat for real-time data analysis. The working electrode (WE) of one SPE was modified with uricase and hydrophilic fumed nano-silica (FSiO₂) for UA sensing, and the WE of the other SPE was modified with gold nanoparticle-reduced graphene oxide (Au NPs/rGO) composites and antibodies for IL-6 sensing. The MES demonstrated excellent analytical performance for the simultaneous detection of UA and IL-6 in human blood, featuring high selectivity, broad linear ranges (10-1000 µM for UA and 0.001-100 ng/mL for IL-6), robust stability, and strong concordance with reference methods (R² > 0.95). This study provides a proof-of-concept platform for gout-related biomarker determination and offers a new strategy for the development of multi-biomarker electroanalytical devices.

This study presents an inchworm-inspired soft intestinal robot powered by a Functionalized Carboxylated Bacterial Cellulose (FCBC)-based ionic actuator and anisotropic frictional feet to enable low-voltage locomotion. A bending ionic electroactive actuator composed of FCBC, Polypyrrole (PPy), and an Ionic Liquid (IL) was fabricated and denoted as FCBC–PPy–IL. The 30 × 6 × 0.8 mm actuator was equipped with silicone anchoring feet patterned with 45° inclined conical protrusions to generate directional friction. Material structure, electrochemical behavior, and cytocompatibility were characterized. Friction was measured on moist ex vivo colonic tissue (0.5–1.5 V, 0.1–10 Hz; end load 0–400 mg). Locomotion was evaluated in confined channels, on colonic surfaces, and within an ex vivo colon lumen. The actuator exhibited reversible, millimeter-scale bending at 0.1–10 Hz with stable output and no cytotoxicity. With anchoring feet, the robot showed pronounced frictional anisotropy, with \(\:{\mu\:}_{\text{r}}\) ≈ 24 (reverse/locking) and \(\:{\mu\:}_{\text{s}}\) ≈ 4 (forward/sliding). Under confinement at ≤ 1.5 V, the robot achieved consistent inchworm-like propulsion, with single-cycle step lengths of 0.031–0.11 mm and a speed of ~ 0.06 \(\:{\text{m}\text{m}\cdot \:\text{s}}^{-1}\) on flat tissue. Free locomotion on inclined surfaces and intraluminal locomotion were further demonstrated at 2.0 V as feasibility demonstrations (~ 0.04 \(\:{\text{m}\text{m}\cdot \:\text{s}}^{-1}\) on a 30° incline). This approach provides an early-stage low-voltage strategy for compliant propulsion and anisotropic-friction anchoring on colonic tissue, supporting future development of soft endoluminal robots.

Radiotherapy (RT) has recently reemerged as a promising approach for melanoma treatment because of its potential to trigger abscopal effects. However, the intrinsic radioresistance of melanoma significantly diminishes RT-induced DNA damage and the subsequent release of immunostimulatory molecules, thereby impairing systemic antitumor immunity. To overcome these challenges, a multifunctional anisotropic Au-Pd heterostructured nanosystem (APSMR) is developed that incorporates a plasmonically enhanced Au-Pd core, with a shell composed of a biodegradable, Mn-doped targeting peptide. The nanosystem integrates photothermal, radiotherapeutic, and immunomodulatory functions. Under 1064 nm laser irradiation, APSMR generates reactive oxygen species (ROS) via plasmon-driven catalysis and Mn-mediated Fenton-like reactions. Concurrently, mild hyperthermia (HT) promotes oxygenation and disrupts DNA repair pathways, resulting in multi-directional DNA damage and an increase in immunogenic cell death (ICD). Furthermore, the release of Mn 2 ⁺ ions activates the cGAS–STING pathway, which synergizes with ICD to promote systemic antitumor immunity. Notably, APSMR treatment also upregulates PD-L1 expression, thereby sensitizing tumors to immune checkpoint blockade. Collectively, APSMR offers a potent and synergistic strategy to amplify RT-driven tumor vaccination and improve therapeutic responses against metastatic melanoma.
