Journal ArticleDOI
Conventional superconductivity at 203 kelvin at high pressures in the sulfur hydride system
TL;DR: S sulfur hydride is investigated, and it is argued that the phase responsible for high-Tc superconductivity in this system is likely to be H3S, formed from H2S by decomposition under pressure, which raises hope for the prospects for achieving room-temperature super conductivity in other hydrogen-based materials.
Journal ArticleDOI
A Heteroleptic Push-Pull Substituted Iron(II) Bis(tridentate) Complex with Low-Energy Charge-Transfer States
Andreas K. C. Mengel,Christoph Förster,Aaron Breivogel,Katharina Mack,Julian Robert Ochsmann,Frédéric Laquai,Vadim Ksenofontov,Katja Heinze +7 more
TL;DR: The combined effect of push-pull substitution and the strong ligand field paves the way for long-lived charge-transfer states in iron(II) complexes.
Journal ArticleDOI
Distinct microbial populations are tightly linked to the profile of dissolved iron in the methanic sediments of the Helgoland mud area, North Sea
Oluwatobi Emmanuel Oni,Tetsuro Miyatake,Sabine Kasten,Tim Richter-Heitmann,David Fischer,Laura Wagenknecht,Ajinkya Kulkarni,M. Blumers,Sergii I. Shylin,Vadim Ksenofontov,Benilde F.O. Costa,Göstar Klingelhöfer,Michael W. Friedrich +12 more
TL;DR: The data suggest that the interplay among JS1 bacteria, methanogenic archaea and Methanohalobium/ANME-3-related archaea may be important for iron reduction and methane cycling in deep methanic sediments of the Helgoland mud area and perhaps in other methane-rich depositional environments.
Journal ArticleDOI
Spin Crossover in Fe(II)-M(II) Cyanoheterobimetallic Frameworks (M = Ni, Pd, Pt) with 2-Substituted Pyrazines.
Olesia I. Kucheriv,Sergii I. Shylin,Sergii I. Shylin,Vadim Ksenofontov,Sebastian Dechert,Matti Haukka,Igor O. Fritsky,Il'ya A. Gural'skiy +7 more
TL;DR: Mössbauer spectroscopy is used to characterize the spin state of all HS, LS, and intermediate phases of 1-9 and effects of a pyrazine substituent and M(II) nature on the hyperfine parameters in both spin states are established.
Journal ArticleDOI
Determining Magnetite/Maghemite Composition and Core–Shell Nanostructure from Magnetization Curve for Iron Oxide Nanoparticles
TL;DR: In this article, the phase composition of the magnetite and maghemite phases of iron oxide magnetic nanoparticles is analyzed using Moser's equation of O(n 2 ).
