Organic phase change materials (PCMs) are considered one of the critical thermal storage materials in medium and low-temperature solar thermal conversion and storage technologies. However, PCMs face challenges such as low photothermal conversion efficiency and liquid leakage, which significantly hinder their practical applications. This study developed a novel paraffin wax/3D graphene-Cu nanowire (PW/GCu) porous composite PCM. Copper nanowires (CuNWs) were embedded as thermal bridge within the GCu aerogel framework. The addition of copper nanowires markedly enhances the photothermal conversion performance and thermal conductivity of the composite material. Specifically, the thermal conductivity of PW/GCu 1.5 reached 0.85 W·m⁻ 1 ·K⁻ 1 , increasing by 347.3% compared to pure PW. The latent heat value reached 165.8 J·g⁻ 1 , approximately 90% of that of pure PW. After 100 thermal cycles, the enthalpy value decreased by only 1.17%. The leakage rate remained below 7%. Under a solar irradiance of 120 mW·cm⁻ 2 , the photothermal conversion efficiency of PW/GCu 1.5 reached 89.5%. Even after 200 photothermal cycles, it maintained excellent photothermal conversion efficiency and rapid thermal response behavior. This combined strategy offers a viable approach for fabricating structurally stable, highly absorbent, efficient heat conversion and storage materials, demonstrating significant application potential in solar thermal utilization.

Lanthanide-doped upconversion nanoparticles (UCNPs) have attracted interest in broad fields but are hindered by intrinsic low photon responsiveness. To overcome the limitation, many strategies have been developed to enhance the performance of UCNPs, including dye sensitization, core–shell engineering, photonic crystal engineering, and so on. While the luminescence intensity has been improved by these methodologies, the terms of luminescence mode diversity have not been further enriched and tunable, such as the wavelength and lifetime, which are from the UCNPs only. In addition, these methodologies are based on a cumbersome preparation process. Herein, we develop an approach to modulate the aggregation of UCNPs through the persistent luminescence (PersL) micrometer particles for upconversion luminescence enhancement. Compared to the individual UCNPs in ethanol, in which emissions are quenched in all directions, the emission of UCNP aggregation on the surface of the PersL micron particles is significantly preserved from quenching. In addition, the near-infrared absorption is increased in UCNP aggregation through the multiple reflection–absorption effect. With the cooperative efforts of suppressive quenching and the enhanced interaction between the incident light and luminescent ions, the UCNPs-PersL systems achieve about a 2-fold enhanced upconversion. Furthermore, promising applications in the realm of dynamic anticounterfeiting have been demonstrated. Thus, this strategy not only realizes enhanced upconversion by modulating the aggregation of UCNPs but also endows the hybrid system with multimodal luminescence.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a leading cause of chronic liver disorders and a growing public health concern. Sterile alpha motif and HD domain-containing protein 1 (SAMHD1), a dNTP triphosphohydrolase, is known for its roles in nucleotide metabolism, antiviral defense, and immune regulation, but its function in hepatocytes and contribution to MASLD pathogenesis remain unclear. In this study, we observed that hepatic SAMHD1 expression was markedly increased in MASLD patient samples and diet-induced MASLD mouse models. In vitro , mimicking MASLD-associated dyslipidemia with palmitic acid, oleic acid, and cholesterol upregulated SAMHD1 expression, an IFN-γ-induced protein, accompanied by increased IFN-γ receptor 1 expression and STAT1 activation in HepG2 cells. Functional studies using SAMHD1-overexpressing and knockdown hepatic cell lines, as well as hepatocyte-specific AAV-mediated SAMHD1 overexpression in vivo , demonstrated that SAMHD1 promoted lipid droplet accumulation. Conversely, hepatocyte-specific SAMHD1 knockout reduced steatosis and liver injury in diet-induced MASLD mouse models. Mechanistically, SAMHD1 enhanced the proteolytic activation of SREBP1 and SREBP2 by upregulating SCAP, S1P, and S2P in a cohesin complex-dependent manner. Collectively, these findings identify hepatocyte SAMHD1 as a promoter of liver steatosis through SREBP activation and highlight it as a potential therapeutic target for MASLD.

In this study, we selected CsPbBr 3 quantum dots (QDs) as a modification layer of CsPbBr 3 /Carbon interface to facilitate their charge transfer for enhancing the photoelectronic conversion efficiency of ZnO/CsPbBr 3 /carbon solar cell. The results demonstrated that CsPbBr 3 QDs layer simultaneously improved film morphology, composition, and optoelectronic properties. This was achieved by filling pinholes, enlarging grain size, suppressing secondary phases, tuning elemental stoichiometry, enhancing electron transport, and reducing non-radiative recombination. The optimized device achieved an increase in PCE from 5.46% to 7.27%. This method and structure of solar cell we proposed in this paper provides a novel strategy for improving high-performance and high-stability PSCs.

CsPbX 3 (X = I, Br, Cl) perovskite quantum dots (QDs) have shown great potential in optoelectronic devices due to their wide tunable bandgap, high photoluminescence quantum yield, and narrow emission spectra. Currently, methods for regulating blue light emission through component engineering or dimensional engineering suffer from issues such as halogen phase separation and increased defects, making it difficult to meet the strict requirements of display technology for pure blue light (CIE y < 0.15). Additionally, traditional synthesis processes are complex and have poor compatibility with Micro-LED miniaturization technology, which restricts their industrial application. Therefore, this study proposes an efficient and green spray drying method. By dissolving the perovskite precursors and halide salts in an aqueous solution, CsPb(Cl/Br) 3 QDs can be rapidly (<10 s) synthesized without organic solvents, and continuous tuning from green to blue light is achieved. This method effectively suppresses surface defects and phase separation through Cl element encapsulation, significantly enhancing stability.Moreover, its excellent processability supports spraying and film formation on any substrate, enabling the direct preparation of highly uniform Mini/Micro-LED pixel units. This technology provides a new approach for large-scale, low-cost manufacturing of perovskite QDs and is expected to accelerate the commercialization process of next-generation display technologies.

Reliable safety assurance for high-energy lithium-ion batteries (LIBs) necessitates real-time internal diagnostics. Herein, an implantable resistive sensor is presented, which is based on CsPbBr₃ nanocrystals (NCs) passivated by zinc acetylacetonate and embedded in a flexible polymer matrix. By integrating the sensor with a random forest (RF) model, the system not only tracks internal electrochemical changes in situ but also accurately predicts future charge/discharge curves and capacity up to 4500 s in advance (R 2 = 0.99). Density functional theory (DFT) confirms that Li + adsorption narrows the bandgap and enhances conductivity, leading to reliable resistance modulation. This study presents a pioneering implantable perovskite-based sensor integrated with machine learning (ML) for predictive battery diagnostics. The proposed platform enables early detection of degradation and provides a low-cost, scalable, and intelligent route toward enhanced battery safety and advanced energy storage management.

Lead halide perovskites have emerged as promising candidates for next-generation optoelectronic devices owing to their tunable bandgaps, high photoluminescence efficiency, and excellent carrier transport characteristics. Low-dimensional nanostructures, particularly nanowires (NWs) and nanoplatelets (NPLs), further enhance these properties through anisotropic charge transport and strong quantum confinement; however, direct morphology-dependent comparisons remain limited. Herein, CsPbBr3 NWs and NPLs were synthesized via a ligand-regulated hot-injection strategy that enables precise dimensional control by tuning ligand ratios. The NWs exhibit uniform one-dimensional (1D) geometry (∼9 nm diameter), whereas NPLs form ∼5 nm-thick two-dimensional (2D) structures. Structural and optical analyses reveal morphology-dependent spectral responses in which NWs show exciton absorption and emission at 505/520 nm, while NPLs display pronounced blue-shifts (465/480 nm) due to enhanced vertical confinement. Time-resolved photoluminescence reveals significantly longer exciton lifetimes in NWs (88.06 ns) than NPLs (32.20 ns), indicating reduced defect density and superior radiative recombination characteristics. Femtosecond transient absorption confirms slower carrier trapping and prolonged hot-carrier relaxation in NWs. This comparative study establishes a direct structure–property relationship between 1D and 2D CsPbBr3 nanostructures, offering insight into morphology-guided design for lasers, single-photon emitters, and blue optoelectronic devices.

Multi-modal sensing platforms have gained significant attention due to enhanced accuracy and self-calibration capabilities, particularly within complex matrices. Targeting the demand for the real-time detection of the food spoilage marker hydrogen sulfide (H 2 S), we introduce a triple-mode sensing platform engineered via 3,4-dihydroxyhydrocinnamic-acid-directed interfacial assembly of flower-like MOF@UCNPs heterostructures that synergize intense up-conversion luminescence with potent peroxidase-mimetic activity. Sulfide selectively coordinates with the Cu 2+ nodes embedded in the MOF, concurrently (i) shutting down nanozyme catalysis, (ii) restoring up-conversion emission, and (iii) attenuating UV–vis absorbance; complementary RGB alterations captured by a smartphone furnish the third read-out. The assay delivers limits of detection of 0.06 μM (fluorescence), 0.22 μM (absorbance) and 0.90 μM (RGB imaging) with excellent linearity, and achieves satisfactory recoveries in complex food matrices. By tracking H 2 S released from meat and eggs stored at different temperatures, real-time freshness assessment is realized on a smartphone. This work not only provides a robust food freshness monitoring tool but also offers a versatile blueprint for rational design of multifunctional nanomaterials toward point-of-need analyte detection.

All-inorganic cesium lead halide perovskite quantum dots (CsPbX 3 QDs) exhibit exceptional optoelectronic properties but suffer from poor stability under ambient conditions, which severely limits their practical applications. In this work, a sequential passivation strategy was developed to simultaneously enhance the photoluminescence quantum yields (PLQYs) and long-term stability of CsPbX 3 QDs. First, 4-bromobutyric acid (BBA) and oleylamine (OLA) were employed as co-ligands during a recrystallization synthesis in aqueous solution, yielding BBA/OLA-capped CsPbX 3 QDs with improved water resistance. Subsequently, the as-prepared QDs were further treated with phenethylammonium bromide (PEABr) to passivate residual surface defects, particularly bromide vacancies, forming a dense hydrophobic ligand shell. Systematic characterization using transmission electron microscopy, X-ray diffraction, UV–vis absorption, photoluminescence spectroscopy, and X-ray photoelectron spectroscopy revealed that the sequential passivation not only refines the morphology and crystallinity but also significantly suppresses non-radiative recombination. The resulting PEABr/BBA/OLA-CsPbX 3 QDs exhibit superior stability under various harsh conditions, including high humidity (70% RH), water immersion, continuous UV irradiation (365 nm), and elevated temperatures (up to 100 °C). As a proof of concept, a white light-emitting diode (WLED) was fabricated using the passivated QDs as the green-emitting layer together with a commercial InGaN blue chip and CsPb(Br/I) 3 red QDs. The device achieves Commission Internationale de l’Éclairage (CIE) color coordinates of (0.3302, 0.3261), a correlated color temperature of 5650 K, and a high color rendering index of 96, demonstrating stable white emission under varying driving currents. This sequential passivation strategy provides a facile and effective route to high-performance, ultra-stable CsPbX 3 QDs for next-generation display and solid-state lighting applications.

MicroRNAs (miRNAs) are important liquid biopsy biomarkers, and their multiplex detection is highly important for the early screening of hepatocellular carcinoma. This work developed a CRISPR/Cas13a biosensing platform based on near-infrared (NIR) light and glutathione (GSH) dual activation for highly sensitive and specific determination of miRNA-21, miRNA-155, and miRNA-224. The advantages of this platform lie in the introduction of GSH-responsive mesoporous silica carriers and photolytic linkers (pc-linkers), which transform the sensing process from “passive triggering” to “controllable activation”, effectively suppressing nonspecific signals. Specifically, GSH can degrade mSiO 2 with tetrasulfide bonds, thereby degrading the carrier. It will release the CRISPR/Cas13a system loaded on the carrier, thereby achieving specific recognition and cleavage of miRNA-21/155; at the same time, 808 nm NIR light excites upconversion nanoparticles (UCNPs) to generate ultraviolet light, which cleaves the pc-linker to activate the detection of miRNA-224. The detection limits of the developed assay for detecting miRNA-21, miRNA-155, and miRNA-224 were 4.2 pM, 5.7 pM, and 0.205 nM, respectively. The recoveries in the serum spiked experiments were 98.97–109.24%, with a relative standard deviation of less than 4.613%, indicating that the method has good accuracy and reliability. This work proposes a novel and reliable strategy for detecting multiple miRNAs in complex biological samples. MicroRNAs (miRNAs) are important liquid biopsy biomarkers, and their multiplex detection is highly important for the early screening of hepatocellular carcinoma.

A flexible, eco-friendly, and photoelectrically modulated
synaptic
resistive random access memory (ReRAM) device has been developed using
a lead-free nanoscale Cs 3 Bi 2 I 9 Quantum
Dot (QD) graphene oxide (GO) composite film. The Ag/PMMA/Cs 3 Bi 2 I 9 QD/GO/ITO device exhibits a remarkable
ON/OFF ratio exceeding 10 4 under illumination, representing
approximately 200-fold enhancement compared to its performance in
darkness (∼10 2 ). The device demonstrates exceptional
mechanical and environmental stability, withstanding 10,000 bending
cycles (4.6 mm radius) and 72 h of ambient exposure (25 ° C, 35%
RH). Furthermore, when implemented in an artificial neural network
(ANN) for supervised learning, the device enables a recognition accuracy
of 94.3%. We attribute this enhanced performance to a synergistic
mechanism associated with the nanoscale dimension and uniform dispersion
of Cs 3 Bi 2 I 9 QD in the composite.
First, a poly(methyl methacrylate) (PMMA) protective layer effectively
suppresses leakage current, thereby elevating the high-resistance
state (HRS). Second, photogenerated holes within the Cs 3 Bi 2 I 9 QD are efficiently trapped, promoting
the formation of I – vacancies (V I – ). This synergistic effect facilitates the formation
of hybrid Ag/V I – conductive filaments,
reducing both SET voltage (by 47.7%) and low-resistance state (LRS)
resistance under illumination. These findings underscore the pivotal
role of optoelectronic coupling in optimizing resistive switching
behavior, paving the way for sustainable neuromorphic computing systems.

Hepatocellular
carcinoma (HCC) remains a significant therapeutic
challenge due to multiple bottlenecks, including low early diagnosis
rates, rapid disease progression, and limited efficacy of monotherapy.
Against this backdrop, multimodal integrated treatment has emerged
as a core solution. Here, we reported a tumor-microenvironment (TME)-activatable
“nano-cocktail” (UMDCAc) that synchronizes photodynamic
(PDT), chemodynamic (CDT), and starvation (ST) therapies for synergistic
HCC eradication. UMDCAc was engineered by growing hollow MnO 2 (HMnO 2 ) on upconversion nanoparticles (UCNPs), coloading
dihydroartemisinin (DHA) and the photosensitizer chlorin e6 (Ce6),
and in situ anchoring ultrasmall gold nanoparticles (AuNPs) that mimic
glucose oxidase (GOx). Surface modification with cyclic RGD peptides
enabled active targeting of α v β 3 integrin. The targeting strategy synergizes with near-infrared (NIR)
light-activated catalysis to enhance therapeutic efficacy. In vitro and in vivo data demonstrate that UMDCAc achieves tumor suppression
through synergistically amplified reactive oxygen species (ROS) generation,
hypoxia relief, and targeted delivery, while maintaining favorable
biocompatibility and safety and exhibiting superior efficacy over
monotherapy. The synergistically generated ROS compromise cellular
antioxidant defenses, induce lipid peroxidation, and double the apoptosis
rate, thereby producing effective antitumor effects. Therefore, this
innovative multimodal strategy offers opportunities for collaborative
cancer therapy.
