Signatures of the bonding-antibonding splitting in the $c$-axis infrared response of moderately underdoped bilayer and trilayer cuprate superconductors

Mallett, Benjamin P. P. ; Maršík, Premysl ; Munzar, Dominik ; Bernhard, Christian ; Dubroka, Adam

In: Physical Review B, 2019, vol. 99, no. 5, p. 054513

We report on results of our analysis of the c-axis infrared conductivity, σc(ω), of bilayer LnBa2Cu3O7−δ (Ln=La, Nd, Y) and trilayer Bi2Sr2Ca2Cu3O10+δ high-Tc superconductors. The analysis employs the multilayer model involving the conductivity of the bilayer or trilayer unit, σbl(ω), and that of the spacing layers separating the latter units, σint(ω). For the YBa2Cu3O7−δ sample...

Sympatric diploid and tetraploid cytotypes of Centaurea stoebe s.l. do not differ in arbuscular mycorrhizal communities and mycorrhizal growth response

Sudová, Radka ; Kohout, Petr ; Kolaříková, Zuzana ; Rydlová, Jana ; Voříšková, Jana ; Suda, Jan ; Španiel, Stanislav ; Müller-Schärer, Heinz ; Mráz, Patrik

In: American Journal of Botany, 2018, vol. 105, no. 12, p. 1995–2007

Genome duplication is associated with multiple changes at different levels, including interactions with pollinators and herbivores. Yet little is known whether polyploidy may also shape belowground interactions.Methods: To elucidate potential ploidy‐specific interactions with arbuscular mycorrhizal fungi (AMF), we compared mycorrhizal colonization and assembly of AMF communities in roots of...

Biological response of an in vitro human 3D lung cell model exposed to brake wear debris varies based on brake pad formulation

Barosova, Hana ; Chortarea, Savvina ; Peikertova, Pavlina ; J. D. Clift, Martin ; Petri-Fink, Alke ; Kukutschova, Jana ; Rothen-Rutishauser, Barbara

In: Archives of Toxicology, 2018, vol. 92, no. 7, p. 2339–2351

Wear particles from automotive friction brake pads of various sizes, morphology, and chemical composition are significant contributors towards particulate matter. Knowledge concerning the potential adverse effects following inhalation exposure to brake wear debris is limited. Our aim was, therefore, to generate brake wear particles released from commercial low-metallic and non-asbestos organic...
