Ni-doped chromite anodes were integrated into electrolyte-supported cells (ESC) with 5×5 cm2 size and investigated in fuel cell mode H2/H2O gas. Both a stoichiometric nominally A-site deficient anode material showed promising performance at 860 °C approaching the ones of state-of-the-art Ni/Gd-doped ceria (CGO) anodes. While difference polarization resistance was small, an increased ohmic perov...

Even though it is a noble metal, silver will corrode in ambient atmospheres, predominantly by reacting with sulfur-containing gases such as hydrogen sulfide (H2S) and carbonyl (OCS) to form the (Ag2S) acanthite. Other aspects of environment, relative humidity presence oxidizing species, also play critical role. With emergence nanoparticles for range technological medical applications, there has...

Lithium-sulfur (Li-S) batteries have gained widespread attention owing to their high theoretical energy density and low cost. However, the commercial application of these is hindered by severe shuttle effect slow redox reaction kinetics polysulfides. In this study, a hierarchically porous membrane consisting CoSe2 nanoparticle-decorated carbon nanofibers containing nanotubes (CoSe2@CNF/CNT) con...

Once nanoparticles enter a biological system, it is known that their surface is instantly covered by the biomolecules present with preference to proteins. This protein corona has been a subject of numerous studies in order to reveal its composition. Besides that, growing interest exists in its quantitative determination in order to gain a deeper insight into the nature of these nanoparticle-pro...

The work presented in this paper makes use of the high-pressure situ imaging capabilities ReactorSTM to demonstrate that single layer 1T Co-promoted MoS 2 can be directly synthesized without any intercalating agents by applying highly reducing conditions during growth. In work, we have sulfided a CoMo nanoparticle precursor supported on Au(111) using H :CH 3 SH gas mixture at 1 bar and imaged c...

The severe “shuttle effect” of dissolved polysulfide intermediates and the poor electronic conductivity sulfur cathodes cause capacity decay lithium–sulfur batteries impede their commercialization. Herein, we synthesized a series well-designed yolk-shelled Fe3O4@carbon (YS-Fe3O4@C) nanocavities with different proportions Fe3O4 as efficient hosts to stabilize intermediates. nanocavity architectu...
