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

open access: yesChemistry – 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

open access: yesJournal 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 ...
