Advantages of highly ionized pulse plasma magnetron sputtering (HIPIMS) of silver for improved E-coli inactivation

César Pulgarin, Juan Kiwi, Rosendo Sanjines, Oualid Baghriche

This study addresses the DC-magnetron sputtering (DCMS) of Ag-films on polyester and compares the results found for the E. coli inactivation with the inactivation obtained when applying highly ionized pulse plasma power magnetron sputtering (HIPIMS). The a ...

Ag-44(SR)(30)(4-): a silver-thiolate superatom complex

Francesco Stellacci, Kellen Michael Harkness

Intensely and broadly absorbing nanoparticles (IBANs) of silver protected by arylthiolates were recently synthesized and showed unique optical properties, yet question of their dispersity and their molecular formulas remained. Here IBANs are identified as ...

Magnetron-Sputtered Ag Surfaces. New Evidence for the Nature of the Ag Ions Intervening in Bacterial Inactivation

César Pulgarin, Juan Kiwi, Rosendo Sanjines

DC-magnetron sputtering with an Ag target on textile surfaces produced Ag particles with sizes similar to 4.7 nm (+/- 15%). Sputtering for 15 s led to Ag layers of 15-20 nm. The threshold sputtering time precluding airborne bacterial growth was about 60 s. ...

Single-molecule-level characterization of supramolecular systems at surfaces

Dietmar Payer

This thesis deals with the self-organization of individual building blocks, specifically organic molecules and metal atoms, into supramolecular structures on metal surfaces under ultra high vacuum conditions (UHV). Self-organization of supramolecular syste ...

Lanthanide Triple-Stranded Helicates: Controlling the Yield of the Heterobimetallic Species

Rosario Scopelliti, Jean-Claude Bünzli, Thomas Binderup Jensen

Two unsymmetrical ditopic hexadentate ligands designed for the simultaneous recognition of two different trivalent lanthanide ions have been synthesized, LAB2 and LAB3, where A represents a tridentate benzimidazole-pyridinebenzimidazole coordination unit, ...

Silver Complexes of Cyclic Hexachlorotriphosphazene

The first solid-state structures of complexed P3N3X6 (X=halogen) are reported for X=Cl. The compounds were obtained from P3N3Cl6 and Ag[Al(OR)4] salts in CH2Cl2/CS2 solution. The very weakly coordinating anion with R=C(CF3)3 led to the salt Ag(P3N3Cl6)2+[A ...

Electronic Structure and Solvation of Copper and Silver Ions: A Theoretical Picture of a Model Aqueous Redox Reaction

Ivano Tavernelli, Leonardo Bernasconi

Electronic states and solvation of Cu and Ag aqua ions are investigated by comparing the Cu2+ + e- -> Cu+ and Ag2+ + e- -> Ag+ redox reactions using d. functional-based computational methods. The coordination no. of aq. Cu2+ is found to fluctuate between 5 ...
