A Rapidly Responsive Sensor for Wireless Detection of Early and Mature Microbial Biofilms

Hubert Girault, Andreas Stephan Lesch, Bhawna Nagar, Wanderson Oliveira Da Silva

Biofilm-associated infections, which are able to resist antibiotics, pose a significant challenge in clinical treatments. Such infections have been linked to various medical conditions, including chronic wounds and implant-associated infections, making the ...

Optical metasurfaces: synthesis, nanofabrication, and colorful applications

Hsiang-Chu Wang

In this thesis, we mainly utilize silver to construct the meta-atoms. Although suffering from easily oxidized, its excellent lossless property throughout the visible range makes it suitable for study. When preserved properly, silver-made metasurfaces can s ...

STEM study of Li4Ti5O12 anode material modified with Ag nanoparticles

Marco Cantoni, Malgorzata Maria Michalska, Mariusz Andrzejczuk

Comprehensive scanning transmission electron microscopy (STEM) analysis of Li4Ti5O12 (LTO) powder modified by deposited Ag nanoparticles was performed. Nanocomposite powders with Ag content of 1 wt.%, 4 wt.%, 10 wt.% were fabricated in a chemical process f ...

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. ...

Electronic excitations induced by the impact of coinage metal ions and clusters on a rare gas matrix: neutralization and luminescence

Wolfgang Harbich, Christoph Sieber

Low energy collisions of atomic ions and cluster ions with rare gas covered metal substrates can lead to strong light emission which is element and size specific. Instead of a direct energy transfer into the electronic system of the cluster the observed em ...
