Boron carbonitride (BCN) nanofibers with rapid and efficient adsorption performance were prepared by electrospinning technology. TEM, XRD, XPS and N adsorption-desorption isotherms were performed to study the microstructure of the nanofibers. The results showed that the BCN fibers synthesized at 1000 °C (BCN-1000) have good crystallinity and high specific surface areas (403 m g). BCN-1000 nanofibers adsorb 70% of amino black 10B (AB-10B) within 10 minutes and reach adsorption equilibrium within 60 minutes. Compared with previous reports, it is found that the adsorption rate of BCN-1000 nanofibers to amino black (AB-10B) is much higher than that of other adsorbents. And BCN nanofibers exhibit a large adsorption capacity (625 mg g). In addition, the process of AB-10B adsorption on BCN nanofibers was systematically investigated, which was in accordance with the pseudo-second-order kinetics model and Langmuir isotherm model.

Article Synopsis
- Scientists created a special gel that helps wounds heal faster and keeps them moist.
- They used strong materials called bacterial cellulose nanofibers to make the gel even tougher and better at fighting bacteria.
- Tests showed that this gel can not only heal wounds quicker but also allows doctors to watch how wounds heal in real-time and helps release medicine when needed.

The aim of this work was to evaluate the expression profile of genes involved in signaling, intracellular and extracellular Ca concentration and apoptosis pathways of osteoblasts in contact with a scaffold made of a composite of BCN/MWCNTs. Osteoblasts were cultivated on BCN, MWCNTs and their mixtures. Osteoblast RNA was extracted for sintering cDNA to amplify genes of interest by PCR; intra- and extracellular calcium (Ca was also quantified.

In heterogeneous catalysis, ease of separation of the catalyst is considered to be important for its effective re-use. In this paper, we report a synthesis of carboxymethyl cellulose stabilized cobalt nanoparticles (CMC-Co) catalyst and their coating on the bacterial cellulose nanofibers (BCN) as high surface area support to prepare the CMC-Co-BCN dip-catalyst strips. The samples were characterized by scanning electron microscopy for surface morphology, X-ray diffraction spectrometry for crystal structure and thermogravimetric analysis for the thermal behavior and estimation of the Co content in the CMC-Co-BCN.
