AI Article Synopsis

  • Commercially available boron nitride nanotubes (BNNTs) and their purified form (pBNNTs) were tested for dispersibility, cytotoxicity, and drug encapsulation in various aqueous solutions.
  • The purified boron nitride nanotubes showed a 37.3% increase in dispersibility and a 27.4% decrease in cytotoxicity compared to their unpurified counterparts.
  • pBNNTs also demonstrated a significant improvement in drug encapsulation, holding 10.4 times more camptothecin than BNNTs, highlighting their potential for biological applications.

Article Abstract

Commercially available boron nitride nanotubes (BNNTs) and their purified form (pBNNTs) were dispersed in aqueous solutions with various dispersants, and their cytotoxicity and drug encapsulation capacity were monitored. Our data suggest that pBNNTs showed an average increase in dispersibility of 37.3% in aqueous solution in the presence of 10 different dispersants. In addition, 100 μg of pBNNTs induced an average decrease in cytotoxicity of 27.4% compared to same amount of BNNTs in normal cell lines. The same amount of pBNNTs can encapsulate 10.4-fold more drug (camptothecin) compared to BNNTs. These data suggest that the purification of BNNTs improves several of their properties, which can be applied to biological experiments and are thus essential in the biological application of BNNTs.

Challenges in Synthesizing Hexagonal Boron Nitride "Quantum" Dots.

Nano Lett

January 2025

School of Physics, Xidian University, No. 2 Taibai South Road, Xi'an 710071, China.

Fluorescent nanodots derived from hexagonal boron nitride (-BN) have garnered significant attention over the past decade. As a result, various synthesis methods─encompassing both bottom-up hydrothermal reactions and top-down exfoliation processes─have been deemed "successful" in producing BN nanodots. Nevertheless, this Perspective emphasizes that substantial challenges remain in the synthesis of "true" nanodots composed mainly of -BN units, as many so-called successful syntheses reported in the literature involve some mischaracterizations.

This study investigated silicone composites with distributed boron nitride platelets and carbon microfibers that are oriented electrically. The process involved homogenizing and dispersing nano/microparticles in the liquid polymer, aligning the particles with DC and AC electric fields, and curing the composite with IR radiation to trap particles within chains. This innovative concept utilized two fields to align particles, improving the even distribution of carbon microfibers among BN in the chains.

This paper presents a comprehensive study of two tool materials designed for the machining of Inconel 718 superalloy, produced through two distinct sintering techniques: High Pressure-High Temperature (HPHT) sintering and Spark Plasma Sintering (SPS). The first composite (marked as BNT), composed of 65 vol% cubic boron nitride (cBN), was sintered from the cBN-TiN-TiSiC system using the HPHT technique at a pressure of 7.7 GPa.

Observing the intricate microstructure changes in abrasive flow machining with traditional experimental methods is difficult. Molecular dynamics simulations are used to look at the process of abrasive flow processing from a microscopic scale in this work. A molecular dynamics model for micro-cutting a single crystal γ-TiAl alloy with a rough surface in a fluid medium environment is constructed, which is more realistic.

Unveiling a Tunable Moiré Bandgap in Bilayer Graphene/hBN Device by Angle-Resolved Photoemission Spectroscopy.

Adv Sci (Weinh)

January 2025

School of Physical Science and Technology, ShanghaiTech Laboratory for Topological Physics, ShanghaiTech University, Shanghai, 201210, P. R. China.

Over the years, great efforts have been devoted in introducing a sizable and tunable band gap in graphene for its potential application in next-generation electronic devices. The primary challenge in modulating this gap has been the absence of a direct method for observing changes of the band gap in momentum space. In this study, advanced spatial- and angle-resolved photoemission spectroscopy technique is employed to directly visualize the gap formation in bilayer graphene, modulated by both displacement fields and moiré potentials.
