In this work, a boronate affinity-functionalized hierarchical mesoporous metal–organic framework adsorbent with boronate sites only in the small mesopore has been structured based on UiO-66@Fe3O4. The introduction of large mesopores in the adsorbent can promote the diffusion of small cis-diol-containing compounds (cis-diols) into small mesopore channels, and the removal of the adsorption sites on the external surface of materials and in large mesopores can enhance the size-exclusion effect of the adsorbent. In addition, the adsorbent has faster adsorption kinetics and excellent selectivity to small cis-diols. Finally, a magnetic dispersive solid-phase extraction coupled with high-performance liquid chromatography was established for the enrichment and detection of nucleotides in plasma. Four nucleotides achieve the recoveries from 93.25 to 118.79%, the limits of detection from 0.35 to 1.26 ng·mL–1, and the intra-day and inter-day relative standard deviations of less than 10.2%. In conclusion, this method can be directly used for the detection of small cis-diol targets in complex biological samples without protein precipitation prior to the extraction.

“…The combination of different elements with specific catalytic, magnetic, electronic, and optical properties as well as surface functionality leads to their outstanding optimized performances. Among these systems, magnetic carbon nanocomposites stand out 2,3,4,5,6 , where the coating of magnetic nanoparticles with carbon, besides providing the desired multifunctionally, enhances thermal and chemical stability, oxidation resistance, ensuring biocompatibility and high specific surface area. A proper control of the functional groups on the carbon surface leads to highly efficient pollutant adsorbents, nanocarriers for drug delivery and cancer therapies, and optimizes the nanocomposite performance as electrocatalysts or energy storage components in lithium batteries.…”

Magnetic Induction Heating (MIH) of magnetite nanoparticles is employed as a novel synthesis procedure of carbon based magnetic nanocomposites. Magnetic nanoparticles (Fe3O4) and fructose (1:2 weight ratio) were mechanically mixed and submitted to a RF magnetic field (305 kHz). The heat generated by the nanoparticles leads to the decomposition of the sugar and to the formation of an amorphous carbon matrix. Two sets of nanoparticles, with mean diameter sizes of 20 and 100 nm, are comparatively analysed. Structural (X-ray diffraction, Raman spectroscopy, Transmission Electron Microscopy (TEM)), electrical and magnetic (resistivity, SQUID magnetometry) characterizations confirm the nanoparticle carbon coating through the MIH procedure. The percentage of the carbonaceous fraction is suitably increased controlling the magnetic heating capacity of the magnetic nanoparticles. The procedure enables the synthesis of multifunctional nanocomposites with optimized properties to be applied in different technological fields. Particularly, Cr (VI) removal from aqueous media is presented employing the carbon nanocomposite with 20 nm Fe3O4 nanoparticles.

Developing highly efficient and stable electrocatalysts is critical for advancing hydrogen evolution reactions (HER) for hydrogen production. Herein, we report a facile approach to fabricating a hierarchical catalyst featuring ruthenium (Ru) nanoparticles uniformly integrated with nitrogen/oxygen co‐doped carbon nanotube aerogels (Ru‐NOCAs). Heteroatoms N and O‐modified CNTs can result in a negatively charged surface to effectively trap Ru3+ ions. Ru‐NOCAs exhibit a well‐defined hierarchical morphology facilitated by the self‐assembly of functional groups on the surface of CNTs, which enhances the interaction between Ru nanoparticles and CNTs. Due to the synergistic effect of hierarchical structure and strong interaction formation, Ru‐NOCAs show excellent catalytic activity and stability. Ru‐NOCAs catalyst demonstrates a remarkable overpotential of 41 mV at 10 mA cm‐2 with a Tafel slope of 57 mV dec‐1 in 1 M KOH and an overpotential of 68 mV with a Tafel slope of 65.8 mV dec‐1 in 0.5 M H2SO4. These results indicate superior catalytic efficiency and enhanced charge transfer kinetics compared to the control samples. This study highlights the effectiveness of incorporating hierarchical structures and tailored surface chemistries in electrocatalyst design, offering new avenues for optimizing HER performance and advancing hydrogen fuel technology.
