Journal ArticleDOI
Cellular Toxicity of Carbon-Based Nanomaterials
Arnaud Magrez,Sandor Kasas,Valérie Salicio,Nathalie Pasquier,Jin Won Seo,Marco Celio,Stefan Catsicas,Beat Schwaller,László Forró +8 more
TL;DR: This work clearly indicated that carbon-based nanomaterials are toxic while the hazardous effect is size-dependent, and cytotoxicity is enhanced when the surface of the particles is functionalized after an acid treatment.
Journal ArticleDOI
Are carbon nanotube effects on green algae caused by shading and agglomeration
Fabienne Schwab,Thomas D. Bucheli,Lungile P. Lukhele,Arnaud Magrez,Bernd Nowack,Laura Sigg,Katja Knauer +6 more
TL;DR: Algal growth test was developed to determine effects of pristine and oxidized CNT on the green algae Chlorella vulgaris and Pseudokirchneriella subcapitata and growth inhibition was highly correlated with the shading of CNT and the agglomeration of algal cells, suggesting that the reduced algal growth might be caused mainly by indirect effects.
Journal ArticleDOI
Tunable polaronic conduction in anatase TiO2.
Simon Moser,Luca Moreschini,Jacim Jacimovic,O. S. Barišić,Helmuth Berger,Arnaud Magrez,Young Jun Chang,Kyoungsik Kim,Aaron Bostwick,Eli Rotenberg,László Forró,Marco Grioni +11 more
TL;DR: Results indicate that anatase can be tuned from an insulator to a polaron gas to a weakly correlated metal as a function of doping and clarify the nature of conductivity in this material.
Journal ArticleDOI
Electric-Field-Induced Skyrmion Distortion and Giant Lattice Rotation in the Magnetoelectric Insulator Cu 2 OSeO 3
Jonathan S. White,Jonathan S. White,Krunoslav Prša,Ping Huang,Arash A. Omrani,Ivica Živković,Marek Bartkowiak,Helmuth Berger,Arnaud Magrez,Jorge L. Gavilano,Gergely Nagy,Jiadong Zang,Henrik M. Rønnow +12 more
TL;DR: Overall, this work presents a new approach to Skyrmion control that makes no use of spin-transfer torques due to currents of either electrons or magnons.
Journal ArticleDOI
In vitro investigation of the cellular toxicity of boron nitride nanotubes
Lenke Horváth,Arnaud Magrez,Dmitri Golberg,Chunyi Zhi,Yoshio Bando,Rita Smajda,Endre Horváth,László Forró,Beat Schwaller +8 more
TL;DR: BNNTs induced extensive multinucleated giant cell formation in macrophages and increased levels of eosinophilia in fibroblasts, and the toxicity of tubular nanomaterials to be strongly correlated with the cellular accumulation enhanced for straight nanotubes.
