Sensitive, on-site and multiple detection of mycotoxins is a vital early-warning tool to minimize food losses and protect human health and the environment. Although paper-based lateral flow immunoassay (LFIA) have been extensively applied in mycotoxins monitoring, low-cost, portable, ultrasensitive and quantitative detection is still a formidable challenge. Herein, a series of Fe-N-C single-atom nanozymes (SAzymes) were synthesized and systematic characterized. The optimal Fe-N-C SAzyme with highly efficient catalytic performance was successfully used as both lab.l and catalyst in lateral flow immunoassays for mycotoxin detection. By taking advantage of the catalytic amplified system, the qualitative and quantitative detection can be easily and flexibly done via observing the test lines by naked eyes or a smartphone, with the LODs of 2.8 and 13.9 pg mL -1 for AFB 1 and FB 1 , which were respectively over 700- and 71000-fold lower than the maximum limit set by the European Union. Besides, underlying catalytic mechanisms and the active sites of the Fe-N-C SAzyme are also investigated by DFT simulation. This work not only provided a promising detection strategy for the application of advanced SAzymes but also offers experimental and theoretical guidelines to understand the active centers of Fe-N-C SAzymes and the catalytic process. © 2022, The Authors.

Magnetic Resonance Imaging (MRI) is now a widely used modality for providing multimodal, high-quality soft tissue contrast images with good spatiotemporal resolution but without subjecting patients to ionizing radiation. In addition to its diagnostic potential, its future theranostic value lies in its ability to provide MRI-guided robot intervention with combined structural and functional mapping, as well as integrated instrument localization, target recognition, and in situ, in vivo monitoring of the therapeutic efficacy. Areas of current applications include neurosurgery, breast biopsy, cardiovascular intervention, prostate biopsy and radiotherapy. Emerging applications in targeted drug delivery and MRI-guided chemoembolization are also being pursued. Whilst promising progress has been made in recent years, there are still significant basic science research and engineering challenges. This paper provides a comprehensive review of the current state-of-the-art in MRI-guided robot intervention and allied technologies in actuation, sensing, new materials, interventional instruments, and interactive/real-time MRI. Potential future research directions and new clinical developments are also discussed.

As a size and shape selective catalyst, zeolites are widely used in petroleum and fine chemicals processing. However, their small micropores severely hinder molecular diffusion and are sensitive to coke formation. Hierarchically porous zeolite single crystals with fully interconnected, ordered and tunable multimodal porosity at macro-, meso- and micro-length scale like in leaves offer the ideal solution. However, their synthesis remains highly challenging. Here we report a versatile confined zeolite crystallization process to achieve these superior properties. Such bio-inspired zeolite single crystals lead to significantly improved mass transport properties by shortening the diffusion length while maintaining shape selective properties, endowing them with an unprecedentedly high efficiency of zeolite crystals, enhanced catalytic activities and cycle time, highly reduced coke formation and reduced deactivation rate in bulky-molecule reactions and methanol-to-olefins process. Their industrial utilization can lead to the design of innovative and intensified reactors and processes with highly enhanced efficiency and minimum energy consumption. © 2020, The Authors.

This work demonstrates surface assembling of partially acidified sodium hyaluronate (SHA) biomacromolecule on drug-loaded metal-organic frameworks nanoparticles (nanoMOFs) that can achieve aqueous lubrication and anti-inflammatory drug release for synergistic therapy of osteoarthritis (OA). Sodium hyaluronate was partially acidified to transform part of the sodium carboxylate to be carboxylic acid (SHA-COOH), which could coordinatively assembled on the UiO-66 and UiO-67 nanocarriers. Surface functionalization of the nanoMOFs with SHA-COOH polymer greatly enhanced their aqueous dispersion stability and lubricating performance due to the strong dipole-charge interaction between sodium ion and water molecules. Reductions over 50% and 96% in both coefficient of friction and wear volume were achieved by adding the UiO-66@SHA-COOH and UiO-67@SHA-COOH in water, which possessed high load-carrying capacity and long-term durability. After loading with aspirin as anti-inflammatory drug, the nanocarriers showed sustained drug release, which benefitted the drug delivery efficiency. Excellent anti-wear performance and extended drug release of the UiO-67@SHA-COOH additives were demonstrated to compare with that of the UiO-66@SHA-COOH due to the higher pore sizes. By co-culturing the aspirin-loaded UiO-67@SHA-COOH with C-28/I2 cells, the nanocarriers showed good biocompatibility and anti-inflammatory effect through tuning the expression of OA-related genes of human normal chondrocytes with inflammation. Our work supported biomacromolecule-functionalized nanoMOFs as a potential dual-functional nanocarriers for biomedical applications. © 2023, The Authors. All rights reserved.

Weyl semimetal Td-phase WTe2 possesses the spin-resolved band structure with strong spin-orbit coupling, holding promises as a useful spin source material. The noncentrosymmetric crystalline structure of Td-WTe2 endows the generation of the out-of-plane polarized spin, which is of great interest in magnetic memory applications. Previously, WTe2 was explored in spin devices based on mechanically exfoliated single crystal flakes with a size of micrometers. For practical spintronics applications, it is highly desirable to implement wafer-scale thin films. In this work, we utilize centimeter-scale chemical vapor deposition (CVD)-grown Td-WTe2 thin films and study the spin current generation by the spin torque ferromagnetic resonance technique. We find the in-plane and out-of-plane spin conductivities of 7.36 × 103 (ħ/2e) (Ωm)–1 and 1.76 × 103 (ħ/2e) (Ωm)–1, respectively, in CVD-growth 5 nm-WTe2. We further demonstrate the current induced magnetization switching in WTe2/NiFe at room temperature in the domain wall motion regime, which may invigorate potential spintronic device innovations based on Weyl semimetals.

Na(+) intercalation pseudocapacitance in graphene-coupled titanium oxide enabling ultra-fast sodium storage and long-term cycling

Sodium-ion batteries are emerging as a highly promising technology for large-scale energy storage applications. However, it remains a significant challenge to develop an anode with superior long-term cycling stability and high-rate capability. Here we demonstrate that the Na(+) intercalation pseudocapacitance in TiO2/graphene nanocomposites enables high-rate capability and long cycle life in a sodium-ion battery. This hybrid electrode exhibits a specific capacity of above 90 mA h g(-1) at 12,000 mA g(-1) (∼36 C). The capacity is highly reversible for more than 4,000 cycles, the longest demonstrated cyclab.lity to date. First-principle calculations demonstrate that the intimate integration of graphene with TiO2 reduces the diffusion energy barrier, thus enhancing the Na(+) intercalation pseudocapacitive process. The Na-ion intercalation pseudocapacitance enabled by tailor-deigned nanostructures represents a promising strategy for developing electrode materials with high power density and long cycle life.
