Aqueous CO2 Reduction by a Re(bipyridine)-Polypyrrole Film Deposited on Colloid-Imprinted Carbon.

Janina Willkomm、Sara Bouzidi、Erwan Bertin 等 5 位作者2020-08-04ChemRxiv

A rhenium-based CO2 reduction catalyst is impregnated in a polymer film deposited on colloidal imprinted carbon. The film's thickness is variable. The catalyst selectively reduces CO2 to CO with good activity and remains stable for up to 24 hours.

Ultra-High Thermoelectric Power Factors in Narrow Gap Materials with Asymmetric Bands

Patrizio Graziosi、Neophytos Neophytou2020-08-04arXiv (Cornell University)

We theoretically unveil the unconventional possibility to achieve extremely high thermoelectric power factors in lightly doped narrow gap semiconductors with asymmetric conduction/valence bands operated in the bipolar transport regime. Specifically, using Boltzmann transport simulations, we show that narrow bandgap ma…

Non-power applications of nuclear energy

William J. Nuttall、Gareth B Neighbour2020-08-04Open Research Online (The Open University)

A brief description of non-power applications of nuclear power is covered in the context of its historical relationship to military nuclear technology developments and the late twentieth-century expansion of commercial nuclear power production. Looking to the future, some potentially attractive non-power commercial op…

Tunable Graphene Split-Ring Resonators

Qiaoxia Xing、Wang, Chong、Huang, Shenyang 等 10 位作者2020-08-04arXiv (Cornell University)

A split-ring resonator is a prototype of meta-atom in metamaterials. Though noble metal-based split-ring resonators have been extensively studied, up to date, there is no experimental demonstration of split-ring resonators made from graphene, an emerging intriguing plasmonic material. Here, we experimentally demonstra…

$Γ$-Valley Transition-Metal-Dichalcogenide Moirè Bands

Mattia Angeli、A. H. MacDonald2020-08-04arXiv (Cornell University)

The valence band maxima of most group-VI transition metal dichalcogenide thin films remain at the $Γ$-point all the way from bulk to bilayer. In this paper we develop a continuum theory of the moirè minibands that are formed in the valence bands of $Γ$-valley homobilayers by a small relative twist. Our effective theor…
