Construction of magnetic nanotubes and transition metal ion generated by acid etching from its own surface (defined as "self-released" systems) can effectively address the issues of complex operation and poor adsorption performance associated with traditional immobilized metal affinity chromatography (IMAC) materials. Based on the magnetic Ni core and polydopamine (PDA) shell, a core-shell structured Ni@PDA magnetic composite nanotubes and their acid-etched product (defined as Ni@PDA-T) were developed and synergistically provided excellent magnetic responsiveness, low cell toxicity and more active sites, enabling efficient magnetic separation and surface Ni²⁺ self-release. Surface self-released Ni²⁺ enabled coordinate capture of histidine-rich proteins without requiring exogenous metal ion supplementation after fixed onto PDA with pH 8.0, simplifying operation and enhancing adsorption efficiency. Given the differences in histidine content among Bovine hemoglobin (BHb), Bovine serum albumin (BSA), and Lysozyme (LYZ), Ni@PDA-T exhibited a maximum adsorption capacity of 4556 mg g^-1 for BHb, which is rich in histidine residues. Density functional theory (DFT) calculations indicate that p-d orbital coordination interactions dominate the Histidine (His) protein's immobilization onto the Ni site and result in superior adsorption behavior for the His protein by DOPAm-Ni²⁺ functional group. SDS-PAGE analysis of mixed protein systems and actual bovine blood samples further confirmed the selective adsorption of BHb by Ni@PDA-T. Chelator-free blood purification was achieved through synergistic coordination between self-released Ni²⁺ and histidine residues, overcoming the reliance on traditional chelating agents.

Organic-fouling inevitable, control achievable: Mitigation strategies in electro-driven membrane systems

Review

作者: Van der Bruggen, Bart ; Chen, Yitao ; Tian, Ruifen ; Gao, Congjie ; Shen, Jiangnan ; Wang, Xiaolin ; Yao, Yuyang ; Wang, Jiabo ; Lin, Yakai

Organic fouling is one of the primary factors limiting the long-term stability of electro-driven membrane systems (EDMS). This review synthesizes evidence on over 60 identified organic-foulants, including organic acids, surfactants, pharmaceuticals, proteins, polysaccharides, and polymers, organizing and evaluating foulants based on molecular size, charge, and cleanability. Systematic comparison reveals that low-molecular-weight and aromatic species penetrate deeply and cause irreversible fouling, while macromolecular and colloidal organics form removable surface layers. We assess trade-offs between aromatic and aliphatic backbones, the role of side-chain functionalities in tuning interfacial affinity, and diverse surface-engineering strategies that enhance resistance to organic fouling. Beyond phenomenological observations, the review highlights multilevel mitigation strategies encompassing pretreatment, electrodialysis reversal, high-frequency pulsing, surface modification, and intelligent cleaning design. In conclusion, while organic fouling remains an inherent challenge, this review confirms that its effects are controllable through integrated material and process strategies, ultimately upholding the central tenet of "Organic-Fouling Inevitable, Control Achievable" and laying the groundwork for next-generation anti-organic-fouling EDMS.

Species delimitation within a taxonomically complex group: An example from the genus Apodemus (Rodentia: Muridae)

Article

Species delimitation based on genetic data plays a critical role in taxonomy research, particularly for resolving taxonomically complex groups and detecting cryptic diversity. However, few studies have assessed the consistency and reliability of the various species delimitation approaches using the real dataset. In this study, we compared the most widely used approaches for species delimitation within the complex group of the Apodemus genus from China. Multiple species delimitation approaches were applied, including the multispecies coalescent model- and machine learning-based approaches. Unexpectedly, we observed considerable discrepancies across methods, with some results lacking taxonomic validity. To resolve the taxonomic puzzle of this taxon, we integrated phylogenetic and population analyses with morphological and ecological assessments, ultimately recognizing nine valid species and identifying one cryptic species. Phylogeographic analyses of endemic lineages in east Himalayan Mountains of Southwest China indicated that orogenic activity and glacial-interglacial cycles have played key roles in the speciation and diversification of Apodemus in China. These results highlight the challenges of species delimitation in taxonomically complex groups and demonstrate that relying solely on molecular methods is insufficient. We advocate an integrative taxonomic framework that combines molecular, morphological, and ecological data to address these taxonomic puzzles.

'Hot Jupiters' may not be orbiting alone

Astronomers challenge longstanding beliefs about the isolation of 'hot Jupiters' and proposes a new mechanism for understanding the exoplanets' evolution. Research led by an Indiana University astronomer challenges longstanding beliefs about the isolation of "hot Jupiters" and proposes a new mechanism for understanding the exoplanets' evolution. While our Jupiter is far away from the sun, hot Jupiters are gas giant planets that closely orbit stars outside our solar system for an orbital period of less than 10 days. Previous studies suggested they rarely have any nearby companion planets, leading scientists to believe that hot Jupiters formed and evolved through a violent process that expelled other planets from the area as they moved closer to their host stars. The research team's findings reveal that hot Jupiters do not always orbit alone. "Our research shows that at least a fraction of hot Jupiters cannot form through a violent process," said Songhu Wang, assistant professor of astronomy in the College of Arts and Sciences. "This is a significant contribution to advance our understanding of hot Jupiter formation, which can help us learn more about our own solar system." Wang presented the results of the research at the June 2023 meeting of the American Astronomical Society in Albuquerque, New Mexico. Researchers analyzed the full, four-year data set for hot and warm Jupiters from NASA's Kepler Mission. Warm Jupiters have a longer orbital period that ranges from 10 to 300 days. Researchers used transit timing variations to determine that at least 12% of hot Jupiters and 70% of warm Jupiters have a nearby planetary companion orbiting their host stars. Wang and his collaborators combined their results with existing observational constraints to propose a new framework for explaining the evolution of hot and warm Jupiters and why some have companion planets. They determined that the makeup of hot and warm Jupiter systems depends on the occurrence of gas giants in the system, which impacts how much the planets interact and migrate. The findings provide a launching point into future research about exoplanets and our solar system's planets. "The ultimate goal for astronomers is to set our solar system into the bigger picture -- 'Are we unique?'" Wang said. "This helps us to understand why we don't have a hot Jupiter in our solar system." Additional collaborators are Dong-Hong Wu, lecturer in the Department of Physics at Anhui Normal University, and Malena Rice, 51 Pegasi b Fellow at the Massachusetts Institute of Technology and incoming professor at Yale University. Wang has long been interested in the configurations and demographics of exoplanets. He uses observational research to try to understand their dynamics and origins, helping astronomers better understand how our solar system fits into a larger cosmic context.
