The stabilization of the formamidinium lead iodide(FAPbI_(3))structure is pivotal for the development of efficient photovoltaic devices.Employing two-dimensional(2D)layers to passivate the threedimensional(3D)perovskite is essential for maintaining the a-phase of FAPbI_(3) and enhancing the power conversion efficiency(PCE)of perovskite solar cells(PSCs).However,the role of bulky ligands in the phase management of 2D perovskites,crucial for the stabilization of FAPbI_(3),has not yet been elucidated.In this study,we synthesized nanoscale 2D perovskite capping crusts with<n>=1 and 2 Ruddlesden-Popper(RP)perovskite layers,respectively,which form a type-Ⅱ 2D/3D heterostructure.This heterostructure stabilizes the a-phase of FAPbI_(3),and facilitates ultrafast carrier extraction from the 3D perovskite network to transport contact layer.We introduced tri-fluorinated ligands to mitigate defects caused by the halide vacancies and uncoordinated Pb^(2+)ions,thereby reducing nonradiative carrier recombination and extending carrier lifetime.The films produced were incorporated into PSCs that not only achieved a PCE of 25.39%but also maintained 95%of their initial efficiency after 2000 h of continuous light exposure without encapsulation.These findings underscore the effectiveness of a phase-pure 2D/3D heterostructure-terminated film in inhibiting phase transitions passivating the iodide anion vacancy defects,facilitating the charge carrier extraction,and boosting the performance of optoelectronic devices. 展开更多

Excitatory amino acid transporters(EAATs) are responsible for excitatory amino acid transportation and are associated with auto-immune diseases in the central nervous system and peripheral tissues.However, the subcellular location and function of EAAT2 in macrophages are still obscure. In this study,we demonstrated that LPS stimulation increases expression of EAAT2(coded by Slc1a2) via NF-κB signaling. EAAT2 is necessary for inflammatory macrophage polarization through sustaining mTORC1 activation. Mechanistically, lysosomal EAAT2 mediates lysosomal glutamate and aspartate efflux to maintain V-ATPase activation, which sustains macropinocytosis and mTORC1. We also found that mice with myeloid depletion of Slc1a2 show alleviated inflammatory responses in LPS-induced systemic inflammation and high-fat diet induced obesity. Notably, patients with type Ⅱ diabetes(T2D) have a higher level of expression of lysosomal EAAT2 and activation of mTORC1 in blood macrophages. Taken together, our study links the subcellular location of amino acid transporters with the fate decision of immune cells,which provides potential therapeutic targets for the treatment of inflammatory diseases. 展开更多

A"once-in-a-millennium"super rainstorm battered Zhengzhou,central China,from 07/17/2021 to 07/22/2021(named"7.20"Zhengzhou rainstorm).It killed 398 people and caused billions of dollars in damage.A pressing question is whether rainstorms of this intensity can be effectively documented by geological archives to understand better their historical variabilities beyond the range of meteorological data.Here,four land snail shells were collected from Zhengzhou,and weekly to daily resolved snail shellδ^(18)O records from June to September of 2021 were obtained by gas-source mass spectrometry and secondary ion mass spectrometry.The daily resolved records show a dramatic negative shift between 06/18/2021 and 09/18/2021,which has been attributed to the"7.20"Zhengzhou rainstorm.Moreover,the measured amplitude of this shift is consistent with the theoretical value estimated from the flux balance model and instrumental data for the"7.20"Zhengzhou rainstorm.Our results suggest that the ultra-high resolutionδ^(18)O of land snail shells have the potential to reconstruct local synoptic scale rainstorms quantitatively,and thus fossil snail shells in sedimentary strata can be valuable material for investigating the historical variability of local rainstorms under different climate backgrounds. 展开更多

Diabetic retinopathy(DR)is the primary cause of blindness in working-age individuals and ranks among the most prevalent complications of diabetes mellitus(DM)worldwide.As the population with diabetes continues to soar,the prevalence of DR is on a rapid upward trajectory[1,2].The International Diabetes Federation(IDF)estimates that by 2045,the global prevalence of DM will reach a staggering 700 million,resulting in a proportional increase in DR cases and imposing substantial societal and economic burdens[2,3]. 展开更多

Recently,in their 2024 study,Dong et al.[1]revealed the pivotal role of neutrophils in the immune response of myocardial ischemia-reperfusion injury(MIRI)via single-cell RNA sequencing(sc RNA-seq),and identified the existence and function of a novel neutrophil subset with repair phenotype,which participates in the cardio-protection of MIRI by regulating the polarization of macrophages via Ym-1.This finding not only deepens our understanding of cellular interactions within MIRI but also opens new therapeutic avenues. 展开更多

Age-related cognitive decline and dementia are significant manifestations of brain aging.As the elderly population grows rapidly,the health and socio-economic impacts of cognitive dysfunction have become increasingly significant.Although clinical treatment of dementia has faced considerable challenges over the past few decades,with limited breakthroughs in slowing its progression,there has been substantial progress in understanding the molecular mechanisms and hallmarks of age-related dementia(ARD).This progress brings new hope for the intervention and treatment of this disease.In this review,we categorize the latest findings in ARD biomarkers into four stages based on disease progression:Healthy brain,preclinical,mild cognitive impairment,and dementia.We then systematically summarize the most promising therapeutic approaches to prevent or slow ARD at four levels:Genome and epigenome,organelle,cell,and organ and organism.We emphasize the importance of early prevention and detection,along with the implementation of combined treatments as multimodal intervention strategies,to address brain aging and ARD in the future. 展开更多

The heavy consumption of non-renewable fossil feedstocks has induced several vital problems such as global warming and energy crises.Biomass,particularly lignin,is a promising renewable resource to substitute fossil fuels for producing value-added chemicals and fuels[1–3].Lignin has a highly irregular and recalcitrant structure that constituted by coumaryl,coniferyl and sinapyl alcohol monomers via intermolecular C–O and C–C bonds in a random order.For a long time,lignin has been regarded as a waste source and burnt for heat.Recently,the high values of lignin as a feedstock to bridge future gaps to supply aromatics have been extensively recognized and various catalytic strategies to transform lignin into arenes,cycloalkanes,etc.have been reported. 展开更多

Water scarcity is a growing global issue due to population growth,water pollution,climate change,and so forth.In remote,arid areas where clean ground water and seawater are unavailable,atmospheric water harvesting(AWH)technology,especially sorption-based AWH(S-AWH)technology,provides a promising means to alleviate local water stress.It utilizes a variety of sorption materials to capture moisture from the air and solar energy to drive the desorption process through heating the sorbents,during which no external power supply such as electricity is required,therefore leaving very few carbon footprints.Following desorption,condensation is usually needed if we were to further collect the water,and the condenser commonly used is a passive component powered by ambient cooling like a glass cover or a cold plate[1].Given the magnitude of atmospheric water($13,000 billion tons)and its flowing characteristics,human extraction will have little influence on it[1,2]. 展开更多
