The Green Lean Amine Machine : Harvesting Electric Power While Capturing Carbon Dioxide from Breath

Kalkus, Trevor J. ; Guha, Anirvan ; Scholten, Philip B. V. ; Nagornii, Dimitrii ; Coskun, Ali ; Ianiro, Alessandro ; Mayer, Michael

In: Advanced Science, 2021, p. 2100995

As wearable technologies redefine the way people exchange information, receive entertainment, and monitor health, the development of sustainable power sources that capture energy from the user's everyday activities garners increasing interest. Electric fishes, such as the electric eel and the torpedo ray, provide inspiration for such a power source with their ability to generate massive...

Carbon‐assisted stable silver nanostructures

Abdollahi, S. Narjes ; Ochoa Martínez, Efraín ; Kilchoer, Cédric ; Kremer, Geoffroy ; Jaouen, Thomas ; Aebi, Philipp ; Hellmann, Tim ; Mayer, Thomas ; Gu, Yibei ; Wiesner, Ulrich B. ; Steiner, Ullrich ; Wilts, Bodo D. ; Gunkel, Ilja

In: Advanced Materials Interfaces, 2020, vol. 7, no. 23, p. 2001227

Nanostructured silver stands out among other plasmonic materials because its optical losses are the lowest of all metals. However, nanostructured silver rapidly degrades under ambient conditions, preventing its direct use in most plasmonic applications. Here, a facile and robust method for the preparation of highly stable nanostructured silver morphologies is introduced. 3D nanostructured...

When plants and plastic interact

Schwab, Fabienne ; Rothen-Rutishauser, Barbara ; Petri-Fink, Alke

In: Nature Nanotechnology, 2020, vol. 15, no. 9, p. 729–730

Overcoming the challenges of plastic detection in plants has made it possible to transfer many of the lessons learned from plant–metal nanoparticle interactions to plastic nanoparticles.

An in vitro lung system to assess the proinflammatory hazard of carbon nanotube aerosols

Barosova, Hana ; Karakocak, Bedia Begum ; Septiadi, Dedy ; Petri-Fink, Alke ; Stone, Vicki ; Rothen-Rutishauser, Barbara

In: International Journal of Molecular Sciences, 2020, vol. 21, no. 15, p. 5335

In vitro three-dimensional (3D) lung cell models have been thoroughly investigated in recent years and provide a reliable tool to assess the hazard associated with nanomaterials (NMs) released into the air. In this study, a 3D lung co-culture model was optimized to assess the hazard potential of multiwalled carbon nanotubes (MWCNTs), which is known to provoke inflammation and fibrosis,...

Rapid and sensitive quantification of cell-associated multi-walled carbon nanotubes

Steinmetz, Lukas ; Bourquin, Joel ; Barosova, Hana ; Haeni, Laetitia ; Caldwell, Jessica ; Milosevic, Ana ; Geers, Christoph ; Bonmarin, Mathias ; Taladriz-Blanco, Patricia ; Rothen-Rutishauser, Barbara ; Petri-Fink, Alke

Evaluating nanomaterial uptake and association by cells is relevant for in vitro studies related to safe-by-design approaches, nanomedicine or applications in photothermal therapy. However, standard analytical techniques are time-consuming, involve complex sample preparation or include labelling of the investigated sample system with e.g. fluorescent dyes. Here, we explore lock-in...
