Size and functional tuning of solid state nanopores by chemical functionalization
No full textWe demonstrate the possibility of using a simple functionalization procedure, based on an
initial vapour-phase silanization, to control the size and functionality of solid state nanopores.
The presented results show that, by varying the silanization time, it is possible to modify the
efficiency of probe molecule attachment, thus shrinking the pore to the chosen size, while
introducing a specific sensing selectivity. The proposed method allows us to tune the nanopore
biosensor adapting it to the specific final application, and it can be efficiently applied when the
pore initial diameter does not exceed a limit dimension related to the mean free path of the
silane molecules at the working pressure.We demonstrate the possibility of using a simple functionalization procedure, based on an initial vapour-phase silanization, to control the size and functionality of solid state nanopores.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
