Chiral inorganic semiconductors with high dissymmetric factor are highly desirable, but it is generally difficult to induce chiral structure in inorganic semiconductors because of their structure rigidity and symmetry. In this study, we introduced chiral ZnO film as hard template to transfer chirality to CsPbBr 3 film and PbS quantum dots (QDs) for circularly polarized light (CPL) emission and detection, respectively. The prepared CsPbBr 3 /ZnO thin film exhibited CPL emission at 520 nm and the PbS QDs/ZnO film realized CPL detection at 780 nm, featuring high dissymmetric factor up to around 0.4. The electron transition based mechanism is responsible for chirality transfer. Graphical Abstract

Rosacea is a chronic inflammatory skin disease that typically affects the central facial area. Its main clinical symptoms include paroxysmal flushing, telangiectasia, and non-temporary erythema. Cell-free adipose tissue extracts (ATEs) are liquid components extracted from human adipose tissue that contain large amounts of growth factors. Despite the scar-reducing, anti-aging, and wound-healing effects of ATEs, the efficacy of ATEs in rosacea remains unknown. Therefore, the anti-rosacea effects of ATEs were investigated in human cathelicidin peptide (LL-37) induced rosacea mice and capsaicin (CAP)-stimulated HaCaT keratinocytes. In vitro, ATEs significantly reduced TRPV1 expression, intracellular calcium ions influx and the release of inflammatory factors (such as KLK5, IL-6, IL-8 and TNF-α) after intervening in CAP-stimulated cells. The in vivo results revealed that ATEs alleviated rosacea symptoms, such as erythema score, erythema area, transepidermal water loss, abnormal epidermal thickness, mast cell infiltration and telangiectasia upon downregulating TRPV1 and CD31 expression. Moreover, the up-regulated TRPV1 protein expression was also recovered by ATEs administration in vivo and in vitro. Meanwhile, ATEs demonstrated good biocompatibility. In summary, ATEs could be a potential therapeutic agent for rosacea by regulating inflammation and alleviating telangiectasia.

Organic light-emitting diodes (OLEDs) supporting the direct emission of circularly polarized (CP) light are essential for numerous technologies. The realization of CP-OLEDs with large dissymmetry ( g EL ) factors and high external quantum efficiencies (EQEs) has been accepted as a considerable challenge. Here we demonstrate the realization of efficient CP-OLEDs based on the assembly of chiral plasmonic nanoparticles (NPs) and supramolecular aggregates. The chiral plasmonic NPs serve as the chiral scaffold and chiral optical nanoantenna to modulate the circularly polarized absorption and emission of the supramolecular chromophores. We employ different chiral plasmonic NPs to construct various CP-OLEDs with the emission dominated by chiral excitons or chiral plasmons. The CP-OLED showing a high EQE of 2.5% and a large g EL factor of 0.31 is achieved, as a result of multiscale chirality transfer, plasmonic enhancement, and the suppression of the overshoot effect. The proposed schemes are compatible with the current manufacturing technology of OLEDs. This work demonstrates that chiral plasmonic NPs can be promising candidates in chiral photoelectric devices.

Circularly polarized luminescence (CPL) in solution offers several advantages. However, it remains challenging for organic molecules to achieve circularly polarized luminescence with high dissymmetry factor ( g lum ) in solution. Herein, a general strategy is developed by placing chiral nematic liquid crystals (N*-LCs) behind the solution of achiral organic molecules. The selective reflection-transmission mechanism of solution-N*-LC composite system enables the generation of full-color and white circularly polarized light with | g lum | even reaching 2.0. This strategy demonstrates versatility, being applicable to both aqueous and organic solutions, and effectively achieving the circularly polarized luminescence of multiple molecules with high g lum values. Additionally, CPL switching and logic gate applications are successfully realized by leveraging the selective reflection-transmission mechanism of N*-LCs and the reversible acid-base responsiveness of the solution systems. This work provides a general and robust strategy for achiral organic molecules to achieve circularly polarized luminescence with high | g lum | values in solutions.

With the rapid development of high-power-density electronic devices, interface thermal resistance has become a critical barrier for effective heat management in high-performance electronic products. Therefore, there is an urgent demand for advanced thermal interface materials (TIMs) with high cross-plane thermal conductivity and excellent compressibility to withstand increasingly complex operating conditions. To achieve this aim, a promising strategy involves vertically arranging highly thermoconductive graphene on polymers. However, with the currently available methods, achieving a balance between low interfacial thermal resistance, bidirectional high thermal conductivity, and large-scale production is challenging. Herein, we prepared a graphene framework with continuous filler structures in in-plane and cross-plane directions by bonding corrugated graphene to planar graphene paper. The interface interaction between the graphene paper framework and polymer matrix was enhanced via surface functionalization to reduce the interface thermal resistance. The resulting three-dimensional thermal framework endows the polymer composite material with a cross-plane thermal conductivity of 14.4 W·m −1 ·K −1 and in-plane thermal conductivity of 130 W·m −1 ·K −1 when the thermal filler loading is 10.1 wt%, with a thermal conductivity enhancement per 1 wt% filler loading of 831%, outperforming various graphene structures as fillers. Given its high thermal conductivity, low contact thermal resistance, and low compressive modulus, the developed highly thermoconductive composite material demonstrates superior performance in TIM testing compared with TFLEX-700, an advanced commercial TIM, effectively solving the interfacial heat transfer issues in electronic systems. This novel filler structure framework also provides a solution for achieving a balance between efficient thermal management and ease of processing.

Silicon holds great potential as anode material for next-generation advanced lithium-ion batteries (LIBs) due to its exceptional capacity. However, its low conductivity and huge volume changes during charge/discharge process result in a poor electrochemical performance of silicon anode. This study introduces a cost-effective strategy to repurpose KL Si waste from photovoltaic industry into feedstock for LIBs. A Si@C composite with core–shell structure was synthesized from kerf loss (KL) Si waste as the primary capacity contributing ingredient. The nanoscale Si particles (Si NPs) was produced through ball milling and acid pickling of KL Si waste, and then coated a carbon shell by the pyrolyzed phenolic resin. This core–shell structure enhances the electrical conductivity of silicon-based anode, facilitates ion/electron movement, and reduces volume fluctuations of silicon during lithiation/de-lithiation process. Compared to the pure Si anode, the Li + transmission efficiency of the Si@C anode was significantly improved, leading to a better cycle and rate performance. The resulting SP-2 electrode demonstrated a consistent capacity of 602 mAh g −1 after 150 cycles under current density of 0.5 A g −1 . Graphical abstract

Seawater electrolysis for hydrogen production has attracted considerable interest due to its sustainability and the abundant availability of seawater. However, the complex composition of seawater poses challenges, such as interference from impurity ions and electrode corrosion caused by chloride ions. In this study, we propose a method for direct seawater utilization in electrolytic hydrogen production, using a combination of anion and cation exchange membranes (AEM and CEM) to effectively prevent ion crossover between seawater and the electrolyte. After 5 consecutive days of electrolysis under optimal conditions, the pH change in the electrolyte was less than 0.1, magnesium and calcium ions from seawater were nearly undetectable on the electrode surfaces, and chloride ion concentrations remained below 100 mM. Our results demonstrate that the combination of AEM and CEM effectively protects the electrodes from seawater impurities, underscoring the feasibility of directly utilizing seawater for hydrogen production through electrolysis.

Manganese ions (Mn 2+ ) have emerged as promising activators of the cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway. However, their clinical application was hindered by low bioavailability and limited immune activation pathways, which impaired their ability to trigger robust immune responses and achieve significant antitumor effects. To address these challenges, we developed a dual-modality immune nano-activator by coordinating manganese ions with quercetin. This strategy was designed to enhance the cGAS-STING pathway activation and elicit the immunogenic cell death, thereby strengthening the antitumor immune response. The engineered nano-activator demonstrated superior tumor-targeting ability and efficient cellular internalization. Upon exposure to near-infrared irradiation, the system harnessed photothermal effects to induce apoptosis in tumor cells while simultaneously accelerating the release of manganese ions and quercetin. The released manganese ions facilitated the generation of reactive oxygen species, which in conjunction with quercetin-induced apoptosis, amplified photothermal-induced DNA damage. This DNA damage further promoted the release of cytosolic DNA, which in turn activated the cGAS-STING pathway, thereby intensifying immune activation. Notably, the nano-activator also triggered immunogenic cell death, which synergized with the cGAS-STING activation to promote dendritic cell maturation and activate antigen-specific T-cell, significantly enhancing the immune response against the tumor. Both in vitro and in vivo studies confirmed that this nano-activator effectively inhibited tumor growth, with particularly pronounced effects when combined with anti-CTLA-4 antibodies.

A dual-recognition strategy is reported to construct a one-step washing and highly efficient signal-transduction tag system for high-sensitivity colorimetric detection of Staphylococcus aureus ( S. aureus ). The porous (gold core)@(platinum shell) nanozymes (Au@PtNEs) as the signal labels show highly efficient peroxidase mimetic activity and are robust. For the sake of simplicity the detection involved the use of a vancomycin-immobilized magnetic bead (MB) and aptamer-functionalized Au@PtNEs for dual-recognition detection in the presence of S. aureus. In addition, we designed a magnetic plate to fit the 96-well microplate to ensure consistent magnetic properties of each well, which can quickly remove unreacted Au@PtNEs and sample matrix while avoiding tedious washing steps. Subsequently, Au@PtNEs catalyze hydrogen peroxide (H2O2) to oxidize 3,3′,5,5′-tetramethylbenzidine (TMB) generating a color signal. Finally, the developed Au@PtNEs-based dual-recognition washing-free colorimetric assay displayed a response in the range of S. aureus of 5 × 10 1 –5 × 10 5 CFU/mL, and the detection limit was 40 CFU/mL within 1.5 h. In addition, S. aureus -fortified samples were analyzed to further evaluate the performance of the proposed method, which yielded average recoveries ranging from 93.66 to 112.44% and coefficients of variation (CVs) within the range 2.72–9.01%. These results furnish a novel horizon for the exploitation of a different mode of recognition and inexpensive enzyme-free assay platforms as an alternative to traditional enzyme-based immunoassays for the detection of other Gram-positive pathogenic bacteria.

Enhancing the efficiency of microbially induced carbonate precipitation (MICP) for soil stabilization is of significant importance for reducing costs and shortening construction timelines, ultimately improving the applicability of MICP technology in engineering. This study developed a novel biocarrier material (Dia@AP-DE) to enhance the efficiency of MICP in cementing sand by immobilizing microorganisms and diversifying calcium carbonate cementation forms. Dia@AP-DE was chemically modified to graft –NH 2 groups onto its surface. These groups protonate to form positively charged –NH 3 + groups, enabling the tight adsorption of negatively charged bacteria through Coulombic interactions. MICP was applied to reinforce sand columns from group B (free bacteria) and group BDAD (Dia@AP-DE immobilized bacteria), and a series of experiments were conducted to analyze the biocarrier’s effects on cementation efficiency, calcium carbonate morphology, and pore structure. Additionally, flow channel evolution within the sand columns was simulated using AVIZO software. The results showed that the BDAD group formed more diverse calcium carbonate cementation forms, particularly the formation of “calcium carbonate bridges.” The bacteria immobilized on Dia@AP-DE produced additional layers of calcium carbonate, which acted as bridges between sand particles, reducing the distance required for effective cementation. Furthermore, flow simulation results indicated that the “calcium carbonate bridges” optimized the uniformity of flow channels within the sand columns during the early stages of injection. Unconfined compressive strength (UCS) tests showed that the strength of the BDAD group was significantly improved at all injection cycles, with UCS values of 1.02 MPa and 5.88 MPa after 3 and 11 injections, respectively, which were 4.6 and 2.0 times higher than those of B group. This study provides a potential new approach for enhancing the efficiency of biocemented soils.

The oxygen evolution reaction (OER) holds pivotal importance in sustainable energy conversion, as it forms the critical half-reaction in various electrochemical processes, including water splitting for hydrogen production and rechargeable metal-air batteries. Here, a CoFe 2 O 4 @Co 3 O 4 nano-composite was synthesized using a facile hydrothermal process and deposited onto the surface of nickel foam through electrophoresis. Characterization using XRD, Raman spectroscopy, and XPS confirmed the successful synthesis of the composite, exhibiting characteristic peaks of both Co 3 O 4 and CoFe 2 O 4 . The nano-composite exhibited a more amorphous phase than pure oxides, benefiting electrocatalytic activity. Scanning and transmission electron microscopy highlighted the composite’s morphological characteristics, showcasing a Co 3 O 4 island distribution on the CoFe 2 O 4 surface. Electrochemical evaluations revealed the superior oxygen evolution reaction (OER) performance of CoFe 2 O 4 @Co 3 O 4 , with low overpotentials, faster kinetics, and enhanced stability compared to pure oxides and the benchmark RuO 2 catalyst. A comprehensive analysis was carried out to investigate the dynamic behavior during electrocatalytic oxygen evolution reaction. This study unveils the intricate charge and electron transfer mechanisms between cobalt and iron atoms, providing insights into their collaborative role throughout the OER process. Graphical Abstract
