Dumbbell silicene: a strain-induced room temperature quantum spin Hall insulator

New Journal of Physics, 2016
By the generalized gradient approximation in the framework of density functional theory, we find a new silicon allotrope (called dumbbell silicene) with high stability, which can turn a quantum spin Hall insulator with an inverted band gap through tuning

Development of a High-Energy-Density Lithiated Silicon-Sulfur Full Cell with Enhanced Stability and Longevity

Silicon-sulfur (Si-S) batteries represent a promising energy storage solution due to their high theoretical energy density. However, practical applications have been hindered by substantial volume expansion of silicon and the dissolution of sulfur ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Sensitivity Enhanced Refractive Index Sensor by Reducing the Influence of In-Plane Wavevector in Photonic Spin Hall Effect

IEEE Photonics Journal, 2018
Photonic spin Hall effect (SHE) can be an effective sensor for determining the refractive index (RI) variation of a sensing medium. How to further improve its sensitivity is a very interesting and important issue.

Spectroscopy of compressed high energy density matter

Physical Review E, 1996
A theoretical and experimental time-resolved spectroscopic investigation of indirectly driven microsphere implosions is described. The plasma dynamics is studied for several fill gases with a trace amount of argon. Through an analysis of the line profile of Ar XVII 1s(2)-1s(3)p P-1, with a line center position at E(v) = 3684 eV, the evolution of the ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This
