Summary: In this study, DFT calculations were performed to investigate the potential application of B36N36 fullerene as a delivery agent for hydroxyurea (HU) and nitrosourea (NU) anticancer drugs. The results showed that both HU and NU interacted with the boron atoms of B36N36 fullerene through their oxygen atoms, exhibiting significant binding energies in both gas and aqueous phases. The study also explored the performances of M-encapsulated B36N36 fullerenes (M = alkali and alkaline earth metals) in adsorbing HU and NU drugs. The release mechanisms were examined using a light-triggered photochemical mechanism. These findings provide valuable insights for the development of boron nitride-based nanocarriers in drug delivery.

Summary: The effect of structural properties of fluorinated graphene (FG) on the supercapacitive properties in KI additive electrolyte was investigated. The adjustment of porous structure and surface F element content of FG through chemical reduction and heating treatment led to a dramatic increase in specific capacitance in KI additive electrolyte compared to pure H2SO4 electrolyte. The relationship between F content and areal capacitance revealed that a small amount of F content, particularly semi-ionic C-F species, can effectively promote the areal capacitance. The assembled symmetric supercapacitor with moderate F content and high specific surface area exhibited an energy density of 8.89 Wh kg-1 and long cyclic stability.

Among them, the Ni@N-C catalyst achieved an excessive CO Faraday efficiency (FECO) (> 90%) on a broad achievable potential window (-0.67 V to -0.97 V vs RHE) in the H-type cell. In the flow cell, the optimized catalyst achieved a FECO of 98% and an industrial-relevant current density of 430 mA cm-2 at -1.07 V vs RHE. This work provides a facile way to fabricate catalysts on a large scale with preeminent performance for industrial CO2 electroreduction to CO.

Summary: Faradic electrode-directed capacitive deionization (faradic-based CDI) is a green and eco-friendly technique with potential in addressing freshwater crisis. However, its practical applications are limited by slow desalination kinetics. In this study, a synergetic strategy combining material design and cell architecture was proposed to improve the desalination rate limit of faradic-based CDI. The integration of ultrasmall Bi nanoclusters impregnated carbon nanofibers as electrodes and a flow-through CDI system resulted in super-fast desalinization and excellent cyclic stability. This research opens up new possibilities for highly-efficient desalination systems based on faradic-based CDI.

Summary: We synthesized a carbon nanotubes-en-capsulated Ni nanoparticles catalyst through a facile chemical vapor deposition approach for electrochemical CO2 reduction (ECR). The Ni@N-C catalyst exhibited the highest CO Faraday efficiency (FECO%) of 90% at -0.77 V vs. RHE in the H-type cell. Moreover, it showed a high FECO% of over 93% within the range of -0.37 to -0.77 V vs. RHE in the flow cell. The excellent catalytic performance of Ni@N-C suggests that N-doped carbon nanotubes coated on Ni nanoparticles play a vital role in promoting ECR activity. This work provides insights into the development of a simple and efficient electrocatalyst for ECR.
