Treatment of Silylene–Phosphinidene with Chalcogens Resulted Exclusively in the Formation of Silicon‐Bonded Chalcogens

Chemistry – A European Journal, Volume 25, Issue 49, Page 11422-11426, September 2, 2019., 2019
Join the main‐group meeting: Chalcogen‐bonded silicon(IV) phosphinidenes LSi(E)−P−MecAAC (E=S, Se, Te) were synthesized from the reactions of silylene–phosphinidene LSi−P−MecAAC with elemental chalcogens. These are the first molecular examples in which a Si=E group is attached to a phosphinidene moiety.

Surface Modification by Combination of Dip‐Pen Nanolithography and Soft Lithography for Reduction of Bacterial Adhesion

Journal of Nanotechnology, Volume 2018, Issue 1, 2018., 2018
Dip‐pen nanolithography (DPN) and soft lithography are techniques suitable to modify the surface of biomaterials. Modified surfaces might play a role in modulating cells and reducing bacterial adhesion and biofilm formation. The main objective of this study was threefold: first, to create patterns at microscale on model surfaces using DPN; second, to ...
