The mechanisms of the microstructural evolution of the TaZrNb/TA15 interface were investigated via SEM, EBSD, EDS, and XRD.Interface mechanical property tests and in-situ tensile tests were conducted on the sphere-containing structure, and an equivalent tensile-strength model was established for the structure. The results revealed that the TA15 titanium alloy and joint had high density and no pores or cracks. The thickness of the planar joint was approximately 50-60 μm. The average tensile and shear strengths were 767 MPa and 608 MPa, respectively. The thickness of the spherical joint was approximately 60 μm. The Zr and Nb elements in the joint diffused uniformly and formed strong bonds with Ti without forming intermetallic compounds. The interface exhibited submicron grain refinement and a concave-convex interlocking structure. The tensile fracture surface primarily exhibited intergranular fracture combined with some transgranular fracture, which constituted a quasi-brittle fracture mode. The shear fracture surface exhibited brittle fracture with regular arrangements of furrows. Internal fracture occurred along the spherical interface, as revealed by advanced in-situ X-ray microcomputed tomography. The experimental results agreed well with the theoretical predictions, indicating that the high-strength interface contributes to the overall strength and toughness of the sphere-containing structure.展开更多

Through isotopic analysis(δ^(13)C_(DIC), δD and δ^(18)O) and hydrochemical measurements [salinity and dissolved oxygen(DO)] of surface and bottom seawater samples from 52 stations, we demonstrate that δ^(13)C_(DIC) values(surface:-3.6‰ to-2.1‰;bottom:-3.6‰ to-1.8‰) exhibit distinct vertical and spatial patterns, with higher values in surface waters and outer bay regions compared to bottom and inner bay areas. Conservative mixing between seawater(average contribution:56%) and freshwater dominates DIC dynamics, while tidal hydrodynamics amplify the imprint of riverine inputs during low tides. Nutrient gradients driven by saline-freshwater mixing enhance primary productivity in outer bay regions,resulting in 13C-enriched DIC and elevated dissolved organic carbon(DOC) concentrations. Conversely, bottom waters show 13C-depleted signatures(-2.75‰ mean δ^(13)C_(DIC)), reflecting organic matter degradation under oxygen-depleted conditions. Aquaculture activities exacerbate localized eutrophication, with monsoon-enhanced runoff amplifying anthropogenic impacts. This work underscores the sensitivity of coastal carbon cycling to both natural hydrodynamics and anthropogenic perturbations in semi-enclosed bays.展开更多

文摘Organic-inorganic metal halides(OIMHs)have emerged as highly promising novel multifunctional optoelectronic materials,owing to their easily adjustable properties from a variety of combinations of different components.But it is still difficult and rare to realize highly tunable multicolor luminescence within the same material.In this work,we successfully incorporated three adjustable emission centers in OIMHs to synthesize a novel OIMH(NEA)_(2)MnBr_(4),with each emission center capable of emitting one of the primary colors—red,green,and blue.The green and red emissions originate from the tetrahedron and octahedron structures in the Mn-based frame,while the blue can be attributed to the contribution of organic components.Additionally,to achieve comparable emission intensity among the three primary colors,we enhanced the blue emission performance by optimizing the ratio of organic structure components and incorporating chirality in the OIMHs.The resulting high-quality films can be obtained by spin-coating method with a photoluminescence quantum yields of up to 96%.More interestingly,by the dual manipulation of excitation wavelength and temperature,the sample can be emitted at least seven distinct colors including a standard white luminescence at(0.33,0.33),opening up promising prospects for multicolor luminescence applications such as high-end anti-counterfeiting technology,light-emitting diodes,X-ray imaging,latent fingerprints,humidity detection,and so on.Therefore,based on application scenarios and requirements,our research on this highly tunable luminescent OIMH material lays a solid foundation for further development of various functional properties of related materials.
文摘Aging is considered the main risk factor for the development of several diseases,including the leading neurodegenerative disorders.While the cellular features of aging are complex and multifaceted,neuronal senescence has emerged as a major contributor and driver of this process in the mammalian cell.Cellular senescence is a programmed response to stress and irreparable damage,which drives the cell into an apoptosis-resistant,non-proliferative state.Senescent cells can also deleteriously affect neighboring,non-senescent cells.Senescence is a complex and multifaceted process associated with a wide range of cellular events,including the secretion of pro-inflammatory molecules and the arrest of the cell cycle.

文摘Traditional p-type colloidal quantum dot(CQD)hole transport layers(HTLs)used in CQD solar cells(CQDSCs)are commonly based on organic ligands exchange and the layer-by-layer(LbL)technique.Nonetheless,the ligand detachment and complex fabrication process introduce surface defects,compromising device stability and efficiency.In this work,we propose a solution-phase ligand exchange(SPLE)method utilizing inorganic ligands to develop stable p-type lead sulfide(PbS)CQD inks for the first time.Various amounts of tin(Ⅱ)iodide(SnI_(2))were mixed with lead halide(PbX_(2);X=I,Br)in the ligand solution.By precisely controlling the SnI_(2)concentration,we regulate the transition of PbS QDs from n-type to p-type.PbS CQDSCs were fabricated using two different HTL approaches:one with 1,2-ethanedithiol(EDT)-passivated QDs via the LbL method(control)and another with inorganic ligand-passivated QD ink(target).The target devices achieved a higher power conversion efficiency(PCE)of 10.93%,compared to 9.83%for the control devices.This improvement is attributed to reduced interfacial defects and enhanced carrier mobility.The proposed technique offers an efficient pathway for producing stable p-type PbS CQD inks using inorganic ligands,paving the way for high-performance and flexible CQD-based optoelectronic devices.

文摘Current research primarily focuses on emerging organic pollutants,with limited attention to emerging inorganic pollutants (EIPs).However,due to advances in detection technology and the escalating environmental and health challenges posed by pollution,there is a growing interest in treating waters contaminated with EIPs.This paper explores biochar characteristics and modification methods,encompassing physical,chemical,and biological approaches for adsorbing EIPs.It offers a comprehensive review of research advancements in employing biochar for EIPs remediation in water,outlines the adsorption mechanisms of EIPs by biochar,and presents an environmental and economic analysis.It can be concluded that using biochar for the adsorption of EIPs in wastewater exhibits promising potential.Nonetheless,it is noteworthy that certain EIPs like Au(III),Rh(III),Ir(III),Ru(III),Os(III),Sc(III),and Y(III),have not been extensively investigated regarding their adsorption onto biochar.This comprehensive review will catalyze further inquiry into the biochar-based adsorption of EIPs,addressing current research deficiencies and advancing the practical implementation of biochar as a potent substrate for EIP removal from wastewater streams.
文摘Solar-driven Fenton-like reactions are promising strategies for degrading pharmaceutical wastewater to address environmental challenges and antibiotic pollution.However,its efficacy is limited by suboptimal light absorption efficiency,rapid charge recombination,and inadequate interfacial charge transfer.In this study,an inorganic/organic S-scheme photo-Fenton system of pseudobrookite/carbon nitride(FTOCN)was synthesized via a hydrothermally coupled calcination process for the effective purification of tetracycline antibiotics under visible-light irradiation.The optimized FTOCN-2 heterostructure exhibits a significantly enhanced TC degradation capacity of 90%within 60 min.The rate constant of FTOCN-2 is 1.6 and 5.2 times greater than those of FTO and CN,respectively.Furthermore,FTOCN exhibits high antibacterial efficacy,highlighting its potential application in the purification of natural water.Measurements via a range of analytical techniques,including Kelvin probe force microscopy,density functional theory calculations,in situ X-ray photoelectron spectroscopy,and femtosecond transient absorption spectroscopy,corroborate the S-scheme mechanism.This study provides a novel perspective for the development of photo-Fenton systems with S-scheme heterojunctions for water purification.

文摘The tensile strain in inorganic perovskite films induced by thermal annealing is one of the primary factors contributing to the inefficiency and instability of inorganic perovskite solar cells(IPSCs),which reduces the defect formation energy.Here,a flexible molecule 5-maleimidovaleric acid(5-MVA)was introduced as a strain buffer to release the residual strain of CsPbI_(2.85)Br_(0.15)perovskite.Maleic anhydride and carboxyl groups in 5-MVA interact strongly with the uncoordinated Pb^(2+)through Lewis acid-base reaction,thus tightly“pull”the perovskite lattice.The in-between soft carbon chain increased the structural flexibility of CsPbI_(2.85)Br_(0.15)perovskite materials,which effectively relieved the intrinsic internal strain of CsPbI_(2.85)Br_(0.15),resisted the corrosion of external strain,and also reduced the formation of defects such as VIand Pb0.In addition,the introduction of 5-MVA improved crystal quality,passivated residual defects,and narrowed energy level barriers.Eventually,power conversion efficiency(PCE)of NiOxbased inverted IPSCs increased from 19.25%to 20.82%with the open-circuit voltage enhanced from 1.164 V to 1.230 V.The release of strain also improved the stability of CsPbI_(2.85)Br_(0.15)perovskite films and devices.

文摘The practical application of aqueous zinc-ion batteries(AZIBs)is primarily constrained by issues such as corrosion,zinc dendrite formation,and the hydrogen evolution reaction occurring at the zinc metal anode.To overcome these challenges,strategies for optimizing the electrolyte are crucial for enhancing the stability of the zinc anode.Inspired by the role of hemoglobin in blood cells,which facilitates oxygen transport during human respiration,an innovative inorganic colloidal electrolyte has been developed:calcium silicate-ZnSO_(4)(denoted as CS-ZSO).This electrolyte operates in weak acidic environment and releases calcium ions,which participate in homotopic substitution with zinc ions,while the solvation environment of hydrated zinc ions in the electrolyte is regulated.The reduced energy barrier for the transfer of zinc ions and the energy barrier for the desolvation of hydrated ions imply faster ion transfer kinetics and accelerated desolvation processes,thus favoring the mass transfer process.Furthermore,the silicate colloidal particles act as lubricants,improving the transfer of zinc ions.Together,these factors contribute to the more uniform concentration of zinc ions at the electrode/electrolyte interface,effectively inhibiting zinc dendrite formation and reducing by-product accumulation.The Zn//CS-ZSO//Zn symmetric cell demonstrates stable operation for over 5000 h at 1 mA cm^(-2),representing 29-fold improvement compared to the Zn//ZSO//Zn symmetric cell,which lasts only 170 h.Additionally,the Zn//CS-ZSO//Cu asymmetric cell shows stable average Coulombic efficiency(CE)exceeding 99.6%over2400 cycles,significantly surpassing the performance of the ZSO electrolyte.This modification strategy for electrolytes not only addresses key limitations associated with zinc anodes but also provides valuable insights into stabilizing anodes for the advancement of high-performance aqueous zinc-ion energy storage systems.
文摘In recent years,chiral inorganic nanomaterials have become promising candidates for applications in sensing,catalysis,biomedicine,and photonics.Plasmonic nanomaterials with an intrinsic chiral structure exhibit intriguing geometry‑dependent optical chirality,which benefits the combination of plasmonic characteristics with chirality.Recent advances in the biomolecule‑directed geometric control of intrinsically chiral plasmonic nanomaterials have further provided great opportunities for their widespread applications in many emerging technological areas.In this review,we present the recent progress in biosensing using chiral inorganic nanomaterials,with a particular focus on electrochemical and enzyme‑mimicking catalytic approaches.This paper commences with a review of the basic tenets underlying chiral nanocatalysts,incorporating the chiral ligand‑induced mechanism and the architectures of intrinsically chiral nanostructures.Additionally,it methodically expounds upon the applications of chiral nanocatalysts in the realms of electrochemical biosensing and enzyme‑mimicking catalytic biosensing respectively.Conclusively,it proffers a prospective view of the hurdles and prospects that accompany the deployment of chiral nanoprobes for nascent biosensing applications.By rational design of the chiral nanoprobes,it is envisioned that biosensing with increasing sensitivity and resolution toward the single‑molecule level can be achieved,which will substantially promote sensing applications in many emerging interdisciplinary areas.

文摘In this study, to meet the development and application requirements for high-strength and hightoughness energetic structural materials, a representative volume element of a TA15 matrix embedded with a TaZrNb sphere was designed and fabricated via diffusion bonding. The mechanisms of the microstructural evolution of the TaZrNb/TA15 interface were investigated via SEM, EBSD, EDS, and XRD.Interface mechanical property tests and in-situ tensile tests were conducted on the sphere-containing structure, and an equivalent tensile-strength model was established for the structure. The results revealed that the TA15 titanium alloy and joint had high density and no pores or cracks. The thickness of the planar joint was approximately 50-60 μm. The average tensile and shear strengths were 767 MPa and 608 MPa, respectively. The thickness of the spherical joint was approximately 60 μm. The Zr and Nb elements in the joint diffused uniformly and formed strong bonds with Ti without forming intermetallic compounds. The interface exhibited submicron grain refinement and a concave-convex interlocking structure. The tensile fracture surface primarily exhibited intergranular fracture combined with some transgranular fracture, which constituted a quasi-brittle fracture mode. The shear fracture surface exhibited brittle fracture with regular arrangements of furrows. Internal fracture occurred along the spherical interface, as revealed by advanced in-situ X-ray microcomputed tomography. The experimental results agreed well with the theoretical predictions, indicating that the high-strength interface contributes to the overall strength and toughness of the sphere-containing structure.

文摘This study investigates the spatial distribution and regulatory mechanisms of dissolved inorganic carbon(DIC) in Xiangshan Bay, East China Sea, addressing critical gaps in carbon cycling research within semi-enclosed bays. Through isotopic analysis(δ^(13)C_(DIC), δD and δ^(18)O) and hydrochemical measurements [salinity and dissolved oxygen(DO)] of surface and bottom seawater samples from 52 stations, we demonstrate that δ^(13)C_(DIC) values(surface:-3.6‰ to-2.1‰;bottom:-3.6‰ to-1.8‰) exhibit distinct vertical and spatial patterns, with higher values in surface waters and outer bay regions compared to bottom and inner bay areas. Conservative mixing between seawater(average contribution:56%) and freshwater dominates DIC dynamics, while tidal hydrodynamics amplify the imprint of riverine inputs during low tides. Nutrient gradients driven by saline-freshwater mixing enhance primary productivity in outer bay regions,resulting in 13C-enriched DIC and elevated dissolved organic carbon(DOC) concentrations. Conversely, bottom waters show 13C-depleted signatures(-2.75‰ mean δ^(13)C_(DIC)), reflecting organic matter degradation under oxygen-depleted conditions. Aquaculture activities exacerbate localized eutrophication, with monsoon-enhanced runoff amplifying anthropogenic impacts. This work underscores the sensitivity of coastal carbon cycling to both natural hydrodynamics and anthropogenic perturbations in semi-enclosed bays.

文摘Sodium-ion batteries have garnered significant attention due to their abundant sodium resources and low cost,showing great potential for large-scale energy storage.However,traditional sodium-ion batteries,which rely on flammable liquid electrolytes as the ion transport medium,pose safety challenges in practical applications.Using solid-state electrolytes instead of liquid electrolytes can effectively improve the safety and electrochemical performance of battery systems,making solid-state sodium-ion batteries as a highly promising option for energy storage.Solid-state electrolytes are categorized into organic and inorganic types.Inorganic solid-state electrolytes have garnered increased interest for their high ionic conductivity,high ion mobility,excellent mechanical properties,and good thermal stability.This review systematically explores the advancements in various inorganic solid-state electrolytes,includingβ-Al_(2)O_(3),sodium superionic conductor,sulfide,halide,complex hydride,and anti-perovskite.The review focuses on material preparation,ionic conductivity,and electrochemical properties.Additionally,it addresses the interface challenges between inorganic solid-state electrolytes and electrode materials,along with effective strategies to improve these interfaces.

文摘Renal cell carcinoma(RCC)as one of the most commonly diagnosed cancers threatens human health.The treatment of RCC demands more advanced protocols for better prognosis and higher quality of life.In recent years,the blooming of nanomaterials in various fields demonstrates its critical role as one of the most important components in constructing a smart therapeutic platform against RCC.Herein,focusing on the therapeutic inorganic nanomaterials(such as carbon nanomaterials,metal nanomaterials,oxide nanomaterials),their functions as drug carriers,external field sensitizers,and/or RCC microenvironment sensitizers are analyzed.In combination with the advantages of nanomaterial and RCC characteristics,the trends in integrating nanomaterial to construct multifunctional theranostic platforms for RCC treatment are highlighted.Also,possible solutions concerning the life trajectory and long-term toxicity of nanomaterials are put forward.These perspectives may promote the development of smarter and more effective systems for comprehensive RCC treatment.

文摘Widespread soil acidification driven by nitrogen(N)fertilization and precipitation challenges the conventional notion of the long-term stability of soil inorganic carbon(SIC)in agroecosystems.However,the changes in SIC with precipitation and N fertilization remain ambiguous.Based on 4,000+soil samples collected in the 1980s and 2010s and by developing machine learning models to fill the missing SIC of soil samples,this study generated 3,697 paired soil samples between the two periods and then investigated the cropland SIC change and explored its relationship with precipitation and N fertilization across the Sichuan Basin,China.The results showed an overall SIC loss,with a decline of the mean SIC by 15.73%.SIC change varied with initial soil pH and initial SIC and exhibited an exponential relationship with soil pH change,indicating the changing role of carbonates in providing acid-buffering capacity.There was a parabolical relationship between the magnitude of SIC decline and N fertilizer rates,and low N fertilizer rates contributed to a reduction in SIC loss,while SIC loss was promoted by N fertilization occurred when N fertilizing rates exceeded 250 kg ha^(-1) yr^(-1).The change in SIC showed a sinusoidal variation with precipitation,with 950 mm being the threshold controlling whether SIC increased or decreased.Meanwhile,N fertilization did not alter the sinusoidal relationship between SIC change and precipitation.In areas with rainfall<950 mm,the high N fertilizer rate did not cause SIC loss,while higher precipitation could also cause larger SIC loss in areas with lower N fertilizer rates.These results suggest that SIC dynamics are jointly driven by precipitation and N fertilization and are controlled by acid-buffering mechanisms associated with initial pH and SIC,with precipitation being the predominant driver.These findings emphasize the need for more regional soil observations and in-depth studies of SIC change and its mechanisms for accurately estimating SIC change.
