A free-standing two-dimensional sheet composed solely of Mo atoms shows metallic character, with an electrical conductivity of ~940 S m−1. Tumesh Kumar Sahu ,Nishant Kumar &Prashant Kumar Article|31 August 2023 Atomically precise vacancy-assembled quantum antidots ...
In this scenario, the interaction strength—either the dipole–dipole coupling, J, or more often the weaker second-order van der Waals shift, V—is larger than the coupling ΩCW from ground to Rydberg states with continuous-wave (CW) lasers, such that excitation of two atoms is prohibited....
1. Atoms A. provided oxygen for the oceans and seas.2. The earth explosion B. combined and formed stars.3. The water on Mars C. stops the heat escaping from the earth.4. The extremely small plants D. could live on land and in the water....
In addition, we study the influence of the joint action of quantum feedback and noise-assisted preparation on quantum coherence and show that the combined action of feedback control and noise-assisted preparation is more effective in enhancing steady coherence. The findings of our research offer ...
In addition, 2D materials doped with than two or more kinds of heteroatoms are also attracted much attention [56,57]. Fig. 2h shows another important defects in 2D materials, the edge sites [2]. The unsaturated atoms at edges will produce remarkable differences in electronic features and ...
A nuclear reaction is a reaction in which the nuclei of the two atoms collide with each other or fuse to form another nucleus and a proton. During this reaction, some amount of energy released.Answer and Explanation: The Nuc...

BP is a layered material that consists of single or multiple layers of phosphorus atoms arranged in a honeycomb structure. It has a puckered structure resulting from the strong covalent bonds within each layer and weak vdW interactions between layers [98,99,100]. The intricate structure endows BP...
Two-electron ORR proceeds on the substitutional S atom with a high charge density, while four-electron ORR occurs simultaneously on the carbon atoms with a high positive spin or charge density. Considering the high electronegativity of Fluorine (3.98), the carbon electronic structure can be ...
graphene layer is doped with B and N atoms, respectively, in a periodic pattern, with the doping concentration as one B or N atom in each lead supercell. The BiP channel part includes 12 unit cells. The vacuum space of 20 Å in the y direction is ...
