Di-(2-ethylhexyl) phthalate (DEHP) is widely used as a plasticizer in plastic products, consumer products, and packaging materials. It is of great health concern in both animals and humans as it released into the environment and entered into the body from plastic products over time, thereby resulting in neurotoxicity. As a pivotal regulator of the central nervous system (CNS), astrocytes, are crucial for maintaining brain homeostasis. Nevertheless, the underlying reason for astrocyte neurotoxicity due to DEHP exposure remains incompletely understood. Here, using an in vivo model of neurotoxicity in quail, this study summarizes that Cx43 is internalized by phosphorylation and translocated to the nucleus as a consequence of DEHP exposure in astrocytes. This study further demonstrated that astrocytes transformed to pro-inflammatory status and induced the formation of autophagosomes. Of note, integrated immunofluorescent codetection approaches revealed an overexpression of the glial fibrillary acidic protein (GFAP) and down-expression of Cx43 in astrocytes. Therefore, in terms of neurotoxicity, this experiment in vivo models directly linked Cx43 internalization to autophagy and neuroinflammation and ultimately locked these changes to the astrocytes of the brain. These findings unveil a potential approach targeting Cx43 internalization for the treatment of neurodegeneration caused by DEHP exposure in astrocytes.

Low-dimensional organic-inorganic hybrid perovskite materials have attracted much attention in photoelectric devices due to their exotic performance in optoelectronics compared with their bulk and thin-film counterparts. In this article, using a simple ligand-assisted deposition method, we successfully synthesized uniform methylammonium lead iodide (MAPbI 3 ) perovskite nanorods, nanotriangles and nanocubes, and investigated their photoelectric properties after fabricated into photodetectors (PDs) on SiO 2 /Si substrates. It is found that the synthesized MAPbI 3 nanorods not only have extremely small optical band gap (minimum of ~1.36 eV), but also have long photoluminescence (PL) lifetime (longest of ~7.81 μs) and high absolute PL quantum yields (maximum of ~ 45%), and the PL lifetime is more than about one order of magnitude higher than that the reported previously. The PDs based on MAPbI 3 nanorods presented a wide spectral response “window” from 350 to at least 950 nm, and exhibited a photoresponsivity of 12.2 mA/W, a detectivity of 2.67 × 10 11 Jones, the on/off ratio of more than 800, the rise/decay time constants of 18/25 ms, under the excitation at 405 nm. Further analysis suggests that the dramatically improved photo-electric conversion properties of the nanorods PDs could be closely related with their morphology dependent properties, including bandgap, PL lifetime, trap density (n trap ) and carrier concentration. These results provide a simple and effective method for preparing different morphology low-dimensional MAPbI 3 , and discuss the mechanism of morphology-dependent photoelectric performance of PDs, which is of great significance for potential applications in the field of photoelectronic devices.

The controlled crystallization process is of significance to the morphological quality of wide-band-gap perovskite absorbers, especially with excessive bromide ions. Moreover, the non-radiative recombination assisted by surface defects is one of the major unfavorable factors that confines the development of highly efficient wide-band-gap perovskite solar cells (PSCs). Here, 1.65 eV wide-band-gap PSCs are constructed by a sequential deposition method with tailored morphology of highly reproducible perovskite absorbers. The controlled crystallization with the help of NH4Cl enables the perovskite films with larger and more uniform grains, which result in less bulk defects. At the same time, (NH4)2SO4 as a passivation layer reduces the uncoordinated Pb2+ and Pb0 defects on the surface of the perovskite film and improves the hydrophobicity due to newly formed insoluble PbSO4. Eventually, the synergistic effect of ammonium salts results in a high VOC of 1.18 V and an optimal efficiency of 20.43%, which is one of the highest power conversion efficiencies for 1.65 eV wide-band-gap-based PSCs constructed by a two-step deposition process. This work confirms that the sequential deposition method and addition of proper ammonium salts are effective strategies toward highly efficient and stable wide-band-gap PSCs.

Flexible dielectric and electronic materials are widely employed in emerging fields. Dielectric energy storage technologies and materials are needed to simultaneously cope with stringent requirements, such as high-stability and compact-size energy storage. Nonetheless, many mainstream polymer dielectrics prematurely fail under the coupling of rising electric field strength and space charge accumulation. Herein, we constructed a one-dimensional core–shell heterogeneous filler (BiFeO3@Al2O3) and added it to wide HOMO–LUMO gap cyanoethyl cellulose, achieving ultrahigh breakdown strength (∼801 MV m−1) and dielectric constant (∼17.3), thus obtaining a substantial discharged energy density of ∼31.3 J cm−3, accompanied by stabilized cyclic charge/discharge of 105. The superior energy storage performance is ascribed to the shell (Al2O3) having a higher work function, forming built-in electric fields with core (BiFeO3), simultaneously decreasing the density of state and increasing the bandgap of nanofibers. This research provides an optimization technique for crafting advanced polymer dielectrics, catering to the evolving demands of modern energy storage applications.

High-quality, stable perovskite films with a wide band gap between 1.65 and 1.80 eV are highly suitable for efficient and cost-competitive silicon-based tandem solar cells. Herein, we demonstrate that the combined strategies of the Pb(SCN)2 additive and air annealing can enable the Cs0.22FA0.78Pb(I0.85Br0.15)3 films with a wide band gap of 1.65 eV and favored properties including pure composition, high crystallinity, micro-sized grains, and reduced defects. With these desired films, the average efficiencies of semitransparent perovskite solar cells (PSCs) are boosted from (18.13 ± 0.31) to (20.35 ± 0.28)%. Further, the semitransparent PSC is used to assemble the four-terminal perovskite/TOPCon tandem solar cell. Benefiting from its excellent performance and preferred optical properties, the obtained tandem solar cell yields a milestone efficiency of 30.32%.

Developing efficient photocatalyst for the photoreduction of CO2and degradation of organic pollutants is an effective alternative to address increasingly serious energy problems and environmental pollution. Herein, the isostructural Sillén–Aurivillius oxyhalides, Bi7Fe2Ti2O17X (X = Cl, Br, and I; BFTOX), are fabricated for CO2reduction and degradation of organic pollutants for the first time. Density functional theory (DFT) calculations show that the valence band maximum (VBM) of BFTOC and BFTOB is contributed by the dispersive 2porbitals of O-atoms, providing the narrow band gap (Eg) and possibly the stability against self-decomposition deactivation. The photocatalytic activities of BFTOX are strongly affected by the halogens (Cl, Br, and I), namely, the BFTOCl sample displays outstanding activity improvement (3.74 μmol·g−1·h−1) for photocatalytic performance. This is mainly attributed to the high separation of charge carriers, small optical band gap, and extended optical absorption. This work focuses on affording a reference to develop efficient and stable photocatalysts from Sillén-Aurivillius layered oxyhalide materials.Keywords:Sillén–Aurivillius;Bi7Fe2Ti2O17X;photocatalyst;degradation;CO2reduction

Four isostructural europium chalcogenides, EuZnGeS4 (1), EuGa2S4 (2), EuIn2S4 (3) and EuIn2Se4 (4), have been synthesized using a high-temperature solid-state method. Single-crystal X-ray diffraction analysis indicates that they crystallize in the orthorhombic space group Fddd with Z = 32. Their structures feature an MQ4 (M = Zn, Ge, Ga and In; Q = S and Se) tetrahedrally constructed 3D network, and Eu2+ ions occupy the bicapped trigonal prismatic cavities. Compounds 1–3 have optical band gaps of 2.26, 2.32 and 2.37 eV, respectively. Theory calculations indicate that 2, with an indirect band gap, can be tuned to 1, with a direct band gap, via simple chemical substitution.

Conjugated microporous polymers (CMPs) have emerged as promising materials for energy storage devices, including lithium-ion batteries (LIBs), owing to their high surface area, chemical tunability, eco-friendliness, and fast redox kinetics. However, their practical applications are limited by poor conductivity, low active material utilization, lower redox potential and cycling degradation, which hampers their utilization for LIBs. Herein, we report the synthesis of dihydrophenazine based CMP (TPA-DPZ) with multi-redox centers and its composite with acid functionalized CNTs equal to only 5% of CNTs by total wt.% of monomers using in situ polymerization technique (TPA-DPZ@CNT 5%). The fabricated cathode with high active material loading of 80% with an average discharge potential of 3.39 V achieved a maximum specific capacity of 128 mAh g −1 . Remarkably, at a higher current density of 20 A g −1 , it retains a capacity of 68.34 mAh g −1 with a discharge time of only 13 s. The electrode exhibits excellent long-term stability, retaining 89% of its initial capacity after 10 000 cycles. It possessed a high energy density of 445 Wh kg −1 (at 0.1 A g −1 ) combined with a high power density of 67 kW kg −1 at 20 A g −1 . This work highlights the synergistic effect of multi-redox CMP and conductive CNTs in overcoming the limitations of organic electrodes.

In this research work, a multi-stage solar steam gap distiller (MSSGD) was designed to enhance the efficiency of solar seawater desalination, addressing the challenges associated with traditional seawater desalination methods, such as difficulties in collecting fresh water, low evaporation efficiency, and the impact of condensation water droplets and water vapor on light absorption. The MSSGD employs three-dimensional disordered porous copper foam as the substrate for light absorber, which is transformed into super-hydrophilic copper oxide foam through thermal oxidation. Subsequently, Zn-Co metal–organic framework (MOF) is in situ grown on CuO foam by a hydrothermal method and carbonized at high temperature, resulting in excellent light absorption capability (97.8 %), self-absorption properties (2.23 cm/s), water activation capacity (873 J/g), and cycle stability. The thickness of air gap and the total number of stages is determined by theoretical calculation and simulation analysis, achieving a maximum evaporation rate of 4.64 kg/m 2 ·h under 1 sun, a water collection rate of 83 %, and a solar-steam efficiency of 201 %. Furthermore, the MSSGD demonstrates favorable evaporation performance and salt tolerance across various seawater salinities, with the produced fresh water meeting WHO standards. This indicates its potential for application in remote water treatment or seawater desalination and lays a foundation for the advancement of solar seawater desalination technology, providing new insights.

Graphical A new AgGaS 2 -type sulfide (Na 0.74 Ag 1.26 )BaSnS 4 with compressed chalcopyrite-like structure was obtained. It exhibits balanced NLO properties, including moderate SHG response, wide band gap, and high LIDT. The development of high-power solid-state lasers is in urgent need of infrared (IR) nonlinear optical (NLO) materials with wide band gaps and high laser-induced damage thresholds (LIDTs). Herein, a new compressed chalcopyrite-like IR NLO crystal (Na 0.74 Ag 1.26 )BaSnS 4 was successfully synthesized using a facile high-temperature solid-state method. Its structure can be considered as a variant of chalcopyrite AgGaS 2 (AGS)-type ones. It features a three-dimensional framework constructed by corner-sharing {[(Na/Ag)S 4 ] 7− } ∞ layers and isolated SnS 4 tetrahedra with negative cavities occupied by counter ion Ba 2+ . (Na 0.74 Ag 1.26 )BaSnS 4 exhibits phase-matchable moderate SHG response (0.31 × AGS), wide band gap (3.70 eV), and high LIDT (6.44 × AGS). Theoretical calculations reveal that the NLO response of (Na 0.74 Ag 1.26 )BaSnS 4 is mainly originated from the synergetic effects of AgS 4 and SnS 4 tetrahedra, and the inclusion of alkaline and alkaline earth metals is responsible for the wide band gap and high LIDT. Moreover, the discovery of this chalcopyrite-like compound will provide a feasible design strategy for the exploration of new promising IR NLO materials.

Lemon emulsion, enriched with vitamin C, organic acids, and dietary fiber, is widely utilized in food applications due to its refreshing flavor and associated health benefits. However, traditional pasteurization (PT) techniques commonly employed to prolong shelf life often lead to nutrient degradation and sensory deterioration. This study investigates the impact of a high-pressure homogenization system integrating piston-gap and microfluidic technologies (IPM-HS) on the quality and stability of lemon emulsions. Emulsions composed of fresh lemon juice, olive oil, and Tween 80 were treated at 200, 300, and 400 MPa. The IPM-HS treatment significantly enhanced turbidity (up to 1.5-fold), reduced particle size below 500 nm, and achieved effective microbial reduction, with no viable microorganisms detected at any pressure level. In addition, EAI and ESI values increased significantly with pressure, indicating enhanced emulsifying capacity and long-term physical stability. Zeta potential measurements showed more negative values after IPM-HS treatment, suggesting improved electrostatic repulsion and greater emulsion stability. The L* value increased markedly from 62.39 to 89.81 at 400 MPa, indicating a shift in color from light yellow to milky white. Emulsions treated with IPM-HS exhibited stable nanostructures with no phase separation during 30-day storage, in contrast to untreated and thermally treated controls. Moreover, total phenolic content increased from 0.49 to 0.58 mg GAE/g ( p < 0.05), and antioxidant activity was well preserved. Flavor analysis using electronic tongue and nose revealed minimal deviation from the control group. Overall, IPM-HS markedly improves emulsion stability, physicochemical quality, and nutritional retention while maintaining sensory attributes, underscoring its potential as a promising non-thermal processing technology for emulsion-based product development.

The development of effectively universal interfacial materials for both conventional and inverted polymer solar cells (PSCs) plays a very crucial role in achieving highly photovoltaic performance and feasible device engineering. In this study, two novel alcohol-soluble conjugated polymers (PBSON-P and PBSON-FEO) with bis(benzothiophene-S,S-dioxide)-fused aromatics (FBTO) as the core unit and amino as functional groups are synthesized. They are utilized as universal cathode interfacial layers for both conventional and inverted PSCs simultaneously. Ascribing to the enlarged conjugated planarity and higher electron affinity for an FBTO unit, both PBSON-P and PBSON-FEO exhibit versatile electron-transporting abilities. They show wide band gaps that are important for light absorption in inverted PSCs, at which point PBSON-P and PBSON-FEO are more progressive than some of the reported small band gap cathode interfacial materials. Importantly, PBSON-P and PBSON-FEO display deep highest occupied molecular orbital energy levels, which can block holes at the cathode and thus increase the fill factor. As a result, both conventional and inverted PSCs using PBSON-P and PBSON-FEO as cathode interlayers realize high photovoltaic performance. Therefore, this series of novel polymers are amphibious cathode interfacial materials for high-performance conventional and inverted PSCs.
