Besides the Langmuir paper mentioned in the previous post, two more manuscripts were accepted from our group for publication in Adsorption on Friday. "Fine tuning of titanate nanostructures' surface acidic sites" summarizes the recent work of Dániel Madarász et el. who measured the surface acidity of titanate nanowires by pyridine adsorption and NH3 TPD. Despite the large number of titanate nanostructure related publications in the literature, this type of data was scarce and difficult to find until now. The acidity of a surface is most important from the heterogeneous catalytic point of view. However, the information will be useful for the solid-fluid interaction research of our Lendület group as well.
The second Adsorption paper was written by Zita Ibolya Papp et al. on the "Effect of planetary ball milling process parameters on the nitrogen adsorption properties of multiwall carbon nanotubes". Specific surface area, pore size distribution and surface fractal dimension were calculated from N2 adsorption-desorption isotherms and compared with nanotube length distribution data derived by TEM image analysis. Ball milling is a facile, industrially available and scaleable way of post-synthetic nanotube property tuning, therefore, we expect these results to be useful for a broad audience interested in nanotube usage. The following figure demonstrates one of the non-trivial findings of this paper: the specific surface area of a ball milled multiwall carbon nanotube sample is inversely proportional with the average nanotube length.
