In recent years, there has been a significant surge ininterest surrounding the synthesis and application of one-dimensional anisotropic perovskites, spurred by ad-vancementsin synthesis techniques and notable breakthroughs in novel methodologies and application proper-ties.This article provides a comprehensive review of the progress made in research on one-dimensionalanisotropic perovskites, detailing the synthesis mechanisms and potential pathways for performance enhance-mentin various applications. We highlight the crucial role of controllable synthesis and heterogeneous effect intailoring perovskite properties to boost application efficacy. Initially, this review examines the primary synthesismethods and mechanisms for creating heterogeneously induced one-dimensional anisotropic perovskites, cate-gorizingthem into two main approaches: the classical wet chemical synthesis, which utilizes selective ligands, andthe ligand-free, substrate-assisted method. The precision in controllable synthesis is essential for fabricatingheterogeneous structures, where the synthesized precursor, shape, and surface ligand significantly influence theinterfacial strength of the heterogenic interface. We also discuss the key features that must be improved for high-performanceapplications, exploring how heterogeneous effects can enhance performance and drive the devel-opmentof heterogeneous devices in various applications, such as photodetectors, solar cells, light-emitting di-odes,and photocatalysis. Conclusively, by highlighting the emerging potential and promising opportunitiesoffered by strategic heterogeneous construction, we forecast a dynamic and transformative future for their pro-ductionand application landscapes.展开更多

Current research on transnational talent flow mainly focuses on the destination countries, with less attention given to the perspective of the sending countries, particularly lacking a dynamic discussion on its impact on technological evolution in the origin countries. Based on the OECD REGPAT database, this paper aims to explore how talent groups migrating to developed countries facilitate the return of knowledge and technology to emerging countries and achieve breakthroughs in their technological evolution paths, while further discussing the potential mechanisms involved. The findings of this paper are as follows:(1) The technological development of emerging countries is a path-dependent process, where countries often branch into new technologies related to their preexisting knowledge base. Consequently, knowledge feedback from high-skilled talents increases the likelihood of sending countries developing unrelated technologies.(2) The mobility of talents across borders fosters more international collaborations and citations for patents that are unrelated to the local knowledge base, thus enriching the technological paths of sending countries.(3) The mobility of high-skilled talents primarily affects complex technologies, which have significant economic effects that encourage imitation by other countries.However, the effect on novel technologies is less significant due to their strong geographical stickiness. In general, this paper addresses the gaps in existing research on talent outflow and the technological evolution of origin countries, providing empirical evidence for the positive role of transnational talent mobility in the technological catch-up of emerging nations.Besides, it offers recommendations for talent export, import, and innovation policy formulation in these countries.展开更多

文摘Biological contaminants(BCs),including but not limited to various pathogens and their endogenous pol-lutants such as intracellular pathogens and antimicrobial resistance genes(ARGs),are ubiquitously detected in effluent of wastewater and drinking water treatment systems which were originally designed to remove common indicator bacteria,resulting in potential impacts on public health.Although there are many emerging technologies that showing promising antimicrobial effects,few have progressed to the actual water scenarios.It’s crucial to understand the main knowledge gaps and thereby design the future developments to better meet engineering requirements.In this review,we first summarize the perfor-mance of conventional water treatment towards BCs removal.Then we showcase the advances of proof-of-concept strategies,including nanotechnology,advanced oxidation process,biological control process and integrated techniques,for BCs control in light of antimicrobial mechanisms,characteristics,proper niches in water treatment,challenges and latest improvements.Further,we proposed a semi-quantitative framework coupling life cycle assessment(LCA)and analytic hierarchy process(AHP)to assess and compare the application potential of representative pilot technologies,in which the antimicro-bial effects,economic issues and sustainability are comprehensively considered.For wastewater treat-ment,non-thermal plasma weights highest among the emerging technologies and outperforms conventional disinfection in terms of efficacy indicators(overall inactivation rate,ARGs removal rate,and growth inhibition),but fall behind overall mainly due to more energy input.Bacteriophage-based treatment has the potential to synergistically inactive the persistent pathogens in combination with con-ventional disinfection,serving as a cost-effective and environmental-friendly supplement.For drinking water treatment,the integrated photocatalytic nanocomposite receives the highest application potential among the emerging technologies and appears to be supplementary or even alternative next-generation disinfectants.This review shares valuable insights to propel the proof-of-concept antimicrobial trials towards industrial procedures.

文摘Oxygen activation leading to the generation of reactive oxygen species(ROS)is essential for photocatalytic environmental remediation.The limited efficiency of O_(2)adsorption and reductive activation significantly limits the production of ROS when employing C_(3)N_(4)for the degradation of emerging pollutants.Doping with metal single atoms may lead to unsatisfactory efficiency,due to the recombination of photogenerated electron-hole pairs.Here,Mn and S single atoms were introduced into C_(3)N_(4),resulting in the excellent photocatalytic performances.Mn/S-C_(3)N_(4)achieved 100%removal of bisphenol A,with a rate constant 11 times that of pristine C_(3)N_(4).According to the experimental results and theoretical simulations,Satoms restrict holes,facilitating the photo-generated carriers’separation.Single-atom Mn acts as the O_(2)adsorption site,enhancing the adsorption and activation of O_(2),resulting the generation of ROS.This study presents a novel approach for developing highly effective photocatalysts that follows a new mechanism to eliminate organic pollutants from water.
