ImportanceUnderstanding the outcomes of artificial light at night (ALAN) on insomnia is crucial for public health, particularly in rapidly urbanizing regions. However, evidence of the association between ALAN exposure and insomnia is limited, despite the large number of people exposed to ALAN.ObjectiveTo explore the association between outdoor ALAN exposure and insomnia among the Chinese population.Design, Setting, and ParticipantsThis cross-sectional study used social media data from Weibo (Sina), a social media platform, and satellite-derived nighttime light images. The study period spans from May 2022 to April 2023. The study encompasses 336 cities across China’s mainland, providing a comprehensive national perspective. Data include insomnia-related posts from the platform users, representing a large and diverse population sample exposed to varying levels of ALAN.ExposureOutdoor ALAN exposure (in nanowatts per centimeters squared per steradian [nW/cm2/sr]) was measured using satellite-derived nighttime light images at a spatial resolution of 500 m.Main Outcomes and MeasuresThe incidence of insomnia among residents at the city level was measured by the number of insomnia-related posts on social media. Multiple linear regression models were used to estimate the association between ALAN exposure and population insomnia, adjusting for population characteristics and meteorological factors at the city level.ResultsThe study included data from 1 147 583 insomnia-related posts. Daily mean ALAN exposure across the 336 cities ranged from 3.1 to 221.0 nW/cm2/sr. For each 5 nW/cm2/sr increase in ALAN exposure, the incidence of insomnia increased by 0.377% (95% CI, 0.372%-0.382%). The association was greater in less populated cities and under extreme temperature and poor air quality conditions. The observed exposure-response functions between ALAN exposure and insomnia demonstrated an upward trend, with steeper slopes observed at low exposures and leveling off at higher exposures.Conclusions and RelevanceThis study provides evidence of the association between increased ALAN exposure and higher incidence of insomnia. These findings expand the current knowledge on adverse health outcomes of ALAN exposure and emphasize the potential health benefits of well-planned artificial nighttime lighting in China and other developing countries in the early stages of city planning.

AbstractThis study demonstrates the development of multifunctional printable piezoelectric actuators using PVDF‐TrFE and PEDOT:PSS, capable of operating at low voltages and supporting a wide range of applications. By leveraging the high piezoelectric coefficient of PVDF‐TrFE and the conductivity of PEDOT:PSS, the actuators exhibit stable performance with precise inkjet printing deposition and optimized waveform parameters. The fabrication process integrates inkjet printing and standard lithography, enabling monolithic integration for high‐performance actuation and multifunctional sensing. The PVDF‐TrFE‐based actuators achieve low‐voltage operation (as low as 50 V), efficient energy transfer, and mechanical stability. Enhancing the beta phase of PVDF‐TrFE resulted in a deflection of ≈600 µm and vortex generation, crucial for lift in aerial robotic applications. Durability tests confirmed minimal performance degradation after 2,300 actuation cycles. Beyond mechanical deflection, the actuators exhibit sound detection and strain sensing capabilities. Experimental evaluations validated their ability to differentiate sound frequencies, detect muscle strain, and replicate bio‐inspired flight dynamics. A preliminary proof of concept for a double‐wing structure demonstrated lift generation at low voltages and resonant frequencies. The results indicate that these piezoelectric actuators are well‐suited for miniaturized robotic applications, particularly in aerial locomotion and multifunctional sensing, opening new possibilities for innovations in micro‐robotics, wearables, and aerial robotics.

Abstract3D printing has been highly pursued owing to its effortless fabrication of custom‐defined geometries, yet the integration of multi‐material with diverse properties in one printed object remains challenging. In this work, a digital light 3D‐printed polymer network that is capable of heterogeneous growth to seamlessly integrate multi‐material is designed. This is accomplished through orthogonal photochemistry design, where visible light is utilized to initiate radical polymerization of acrylates for 3D printing. Inspired by plants’ phototropism due to uneven auxin distribution, UV light is employed to induce spatiotemporal catalyst generation for promoting network heterogeneous growth. In this process, it is found that the UV‐generated catalyst effectively facilitates the hydrolysis of ketals to produce hydroxyls, which can further serve as “growing sites” to initiate the ring‐opening polymerization of polycaprolactone. This enables precise manipulation of both shape and mechanical properties in 3D‐printed objects. The distinctive heterogeneous growth mechanism of 3D printing enables the production of multi‐material components using a single resin.

AbstractDue to its soft lattice characteristics, all‐inorganic cesium lead halide (CsPbI3‐xBrx) perovskite is vulnerable to external environmental stress such as moisture, polar solvent, illumination. resulting in structural defects (VI, Ii, etc.) and ion mobility. However, most of the prior arts focus on short‐term and static passivation, which has a negligible effect on defects formed during solar cell operation. Herein, a photoisomerizable molecule, 1,3,3‐trimethylindolino‐8′‐methoxybenzopyrylospiran (OMe‐SP), exhibiting light‐driven pre‐isomeric (SP) and post‐isomeric (PMC) configurations, is employed as an interfacial protective layer on top of CsPbI3‐xBrx. The present strategy not only effectively suppresses migration of halogen ions, but also enables sustainable passivation of defects, thereby significantly reducing interfacial charge recombination and retarding perovskite degradation. Consequently, the OMe‐SP‐modified perovskite solar cells (PSCs) exhibit superior stability, maintaining 91% of their initial efficiency after aging 1032 h under maximum power point (MPP) tracking and continuous one sun illumination. Meanwhile, the OMe‐SP‐modified cell also achieves an impressive power conversion efficiency of 22.20%, which stands as the highest among all‐inorganic perovskite solar cells. Overall, the implementation of this robust strategy provides sustainable defect passivation and continuous suppression of ion migration for achieving both high PCE and stable inorganic perovskite.

AbstractThe interface energy level alignment modulation and charge carrier transportation play an important role in the device performance of perovskite solar cells (PSCs). Herein, tailored hydrophobic metal‐organic frameworks (MOFs) are employed as interfacial layers between perovskite absorbers and hole transport layers (HTLs). The tailored MOFs feature abundant carboxylic acid groups capable of bonding with Pb2+ and organic cations, which can effectively passivate interface defects and suppress non‐radiative recombination. Meanwhile, the MOF interfacial layers optimized the energy level alignment between the perovskite and the HTL, further facilitating carrier transportation. Specifically, the CsFAMA‐based PSCs with a bandgap of 1.63 eV attained power conversion efficiency (PCE) of 23.06% upon modification with MOFs. Additionally, the MOFs‐treated FA‐based PSCs with a bandgap of 1.55 eV achieved a remarkable PCE of 24.81%, accompanied by an outstanding fill factor of 84.3% and a minimal open‐circuit voltage loss of merely 0.386 V. Furthermore, the integration of the MOF interfacial layer substantially improved the moisture stability of the PSCs. The unencapsulated CsFAMA PSCs modified with MOFs retained 91.2% of their initial efficiency after 2500 h of aging under ambient conditions with 40% relative humidity (RH). This work underpins the commercialization of PSCs with diverse bandgaps.

AbstractAxonal growth is heavily influenced by topography and biophysical stimuli including magnetic and electrical fields. Despite extensive investigation, the degree of influence and the underlying genetic mechanisms remain poorly understood. Here, a novel approach to guide neurite growth is undertaken using an innovative ferromagnetic composite material – glass‐coated magnetic microwire – to furnish a synergistic combination of magnetic and topographical cues. Whole rat dorsal root ganglia (DRG) are cultured under five different conditions: control, static magnetic field, magnetic microwire, static magnetic field + glass fiber, and static magnetic field + magnetic microwire. DRG outgrowth responses under each condition, including total neurite outgrowth and directionality, are compared. The combination of both magnetic stimulation and topography significantly increases total neurite outgrowth compared to the controls. The combination of magnetic stimulation and magnetic microwire lead to a strong directional bias of growth along the microwire, double what is observed with the glass fiber. Next generation RNA sequencing of DRG exposed to static magnetic field + magnetic microwire reveals the downregulation of genes relating to the immune response, interleukin signaling, and signal transduction. These results set the stage for contemplating future biophysical stimulation for axonal guidance and improved understanding of material‐tissue interactions.

AbstractNanostructured titania, TiO2, holds significant importance in various scientific fields and technologies for their distinctive properties and multipurpose characteristics. In this article, the facile, economical, and scalable synthesis of 1D lepidocrocite, 1DL, titania nanostructures derived from a water‐soluble Ti precursor, titanium oxysulfate (with oxidation of Ti+4) at temperature <100 °C under atmospheric pressure is discussed. Titanium oxysulfate with tetramethyl ammonium hydroxide, TMAH, is simply reacted to yield individual lepidocrocite titania‐based chain‐forming nanofilaments, NFs, 6 × 6 Å2 in minimal cross‐section and aspect ratios of ≈20 1DLs. If only ethanol is used for washing, the 1DL self‐assemble into ≈10 µm, porous mesostructured particles, PMPs. If water is used, quasi‐2D sheets form instead. Characterization of the resulting powders showed them to be quite similar to those derived from TiB2, and other water‐insoluble Ti precursors. The 1DL bandgap energies are ≈4 eV, due to quantum confinement. They adsorbed rhodamine 6G. The latter also sensitized the 1DLs and allowed for dye degradation using only visible light. Used as electrodes in supercapacitors, the 1DLs can be cycled over 1.6 V and result in high power densities (300 W kg−1). Stronger birefringence started to appear in samples with concentrations >15 gL−1 indicating the formation of a liquid crystal phase. This new synthesis protocol enables the cheaper scalable production of 1DLs with significant implications across various fields.

AbstractSeveral studies have observed renal cell ferroptosis during cisplatin‐induced acute kidney injury (AKI). However, the mechanism is not completely clear. In this study, oxidized arachidonic acid (AA) metabolites are increased in cisplatin‐treated HK‐2 cells. Targeted metabolomics showed that the end product of pyrimidine biosynthesis is decreased and the initiating substrate of pyrimidine biosynthesis is increased in cisplatin‐treated mouse kidneys. Mitochondrial DHODH, a key enzyme for pyrimidine synthesis, and its downstream product CoQH2, are downregulated. DHODH overexpression attenuated but DHODH silence exacerbated cisplatin‐induced CoQH2 depletion and lipid peroxidation. Mechanistically, renal DHODH acetylation is elevated in cisplatin‐exposed mice. Mitochondrial SIRT3 is reduced in cisplatin‐treated mouse kidneys and HK‐2 cells. Both in vitro SIRT3 overexpression and in vivo NMN supplementation attenuated cisplatin‐induced mitochondrial DHODH acetylation and renal cell ferroptosis. By contrast, Sirt3 knockout aggravated cisplatin‐induced mitochondrial DHODH acetylation and renal cell ferroptosis, which can not be attenuated by NMN. Additional experiments showed that cisplatin caused mitochondrial dysfunction and SIRT3 SUMOylation. Pretreatment with mitochondria‐target antioxidant MitoQ alleviated cisplatin‐caused mitochondrial dysfunction, SIRT3 SUMOylation, and DHODH acetylation. MitoQ pretreatment protected against cisplatin‐caused AKI and renal cell ferroptosis. Taken together, these results suggest that mitochondrial dysfunction‐evoked DHODH acetylation partially contributes to renal cell ferroptosis during cisplatin‐induced AKI.

AbstractAccurate non‐invasive monitoring of blood glucose (BG) is a challenging issue in the therapy of diabetes. Here near‐infrared (NIR) photoplethysmography (PPG) sensor based on a vapor‐deposited mixed tin‐lead hybrid perovskite photodetector is developed. The device shows a high detectivity of 5.32 × 1012 Jones and a large linear dynamic range (LDR) of 204 dB under NIR light, guaranteeing accurate extraction of eleven features from the PPG signal. By a combination of machine learning, accurate prediction of blood glucose level with mean absolute relative difference (MARD) as small as 2.48% is realized. The self‐powered PPG sensor also works for real‐time outdoor healthcare monitors using sunlight as a light source. The potential for early diabetes diagnoses by the perovskite PPG sensor is demonstrated.

AbstractResearch on magnetically resonant wireless power transfer (MRWPT) is actively pursued for diverse applications. Dependent on magnetic fields for wireless power transfer (WPT), MRWPT encounters a challenge due to the absence of monopole magnetic properties, impacting power transfer efficiency (PTE) sensitivity to receiver arrangement. Despite extensive research, achieving the desired receiver freedom remains a persistent challenge—a core limitation rooted in magnetic field‐based WPT. To address this, electrically resonant wireless power transfer (ERWPT) is proposed, utilizing an open bifilar coil at a resonant frequency. Experimental results demonstrate nonradiative power transfer of up to 50 watts and 46% PTE over a distance of 2 meters, maintaining consistent PTE performance. This phenomenon arises from the electric charge's monopole capability, distinguishing it from the limitations associated with magnetic fields. The practical viability of this system is delved and suggest directions for further investigation. ERWPT overcomes MRWPT challenges, ensuring lateral plane consistent efficiency and offering a breakthrough for practical wireless power applications.

AbstractAchieving high efficiency over large areas remains a significant bottleneck in commercializing perovskite solar cells (PSCs). Recent advancements in passivation technology, especially using self‐assembled monolayers (SAMs) to address buried interface defects, have been instrumental in boosting the efficiency of PSCs. However, SAMs' compactness, uniformity, and wettability are crucial factors influencing the quality of perovskite films. This study presents a buried interface layer based on NiOx/mesoporous Al2O3 sponge as a carrier for SAM solution adsorption, combined with a dip coating process, successfully developing a large‐area preparation technology for SAM layers. The results indicate that the compact SAM layer deposited by this approach effectively passivates buried interface defects on a large scale, while the enhanced wettability of the Al2O3 layer aids in eliminating interfacial voids. The modified PSCs with an active area of 0.09 cm2 achieve a power conversion efficiency (PCE) of 25.46%. The device attains a champion PCE of 22.66%, marking one of the highest efficiencies reported for p‐i‐n PSMs prepared via large‐area coating in mini‐modules (10–200 cm2) under air ambient conditions. Moreover, encapsulated devices retain 93.8% of their initial PCE after 1000 h of continuous operation under one‐sun equivalent intensity at 65 °C in an air environment.

AbstractThe modulation of heterointerfaces in 2D materials is critically important for improving the electrochemical performance of sodium‐ion batteries (SIBs). In this context, the MoS2/Ti3C2Tx MXene heterostructure is taken as a typical example to reveal the fundamental principle of high sodium storage performance by regulating the terminal groups of Ti3C2Tx. It is demonstrated that MoS2/Ti3C2(OH)x (M/‐(OH)x) heterostructure with a high work function difference generates an enhanced built‐in electric field, which facilitates charge transfer. Moreover, ether‐based electrolytes, when compared to ester‐based electrolytes, provide lower solvation‐free energies and exhibit high compatibility with M/‐(OH)x, resulting in superior rate capability. Notably, COMSOL simulations of sodium ion (Na+) concentration and Na+ flux distributions reveal that the M/‐(OH)x electrode has low concentration polarization and rapid diffusion kinetics in ether‐based electrolytes. Consequently, the combination of M/‐(OH)x heterostructure with the ether‐based electrolyte provides 224.06 mAh g−1 after 1000 cycles at 5.0 A g−1. Furthermore, the Na3V2(PO4)3/C//M/‐(OH)x full cell demonstrates robust electrochemical performance, delivering 116.49 mAh g−1 after 140 cycles at 1.0 A g−1. These findings emphasize the impact of modulating terminal functional groups to optimize the electrochemical functionality of heterostructures and highlight the crucial role of electrode/electrolyte synergistic coupling in advancing the practical applications of SIBs.
