Confining CO molecules in stable orbits
نویسندگان
چکیده
A scheme is presented for the confinement of neutral molecules in stable orbits on the basis of the linear Stark effect in a properly designed electrostatic trap. Based on Stark shift measurements in electric fields up to 140 kV/cm, an electrode configuration which is, under realistic experimental conditions, capable of confining metastable CO(a31-1) molecules with velocities up to 22 m/s is described. Metastable CO molecules can be laser-prepared inside the trap and their trajectories can be directly visualized via the spatially resolved detection of their fluorescence.

In this research. CO gas molthules were approached to single-wall carbon nanotube (SWNT) and (6,0) CNTsurface from carbon side and oxygen side in three states (top, bridge, centre) and two shapes ( erlica I.horizontal), then adsorption energies were calculated by B3TYP/6-310 B3LYPI3-216" and Hge3-210"methods after that they were compared m order to obtain the most stable adsorption state.

متن کاملLong-term stability of horseshoe orbits
Unlike Trojans, horseshoe co-orbitals are not generally considered to be long-term stable. As the lifetime of Earth’s and Venus’s horseshoe co-orbitals is expected to be about a Gyr, we investigated the possible contribution of late-escaping inner planet co-orbitals to the lunar Late Heavy Bombardment. Contrary to analytical estimates, we do not find many horseshoe objects escaping after the fi...
متن کاملOrientational orders of small anisotropic molecules confined in slit pores.
Based on a constant-pressure Monte Carlo molecular simulation, we have studied orientationally ordered transitions of small anisotropic molecules confined in two parallel hard walls. These molecules are modeled by the hard Gaussian overlap model. The molecular elongations of the chosen molecules are so small that the molecules cannot form stable liquid-crystal (LC) phases in the bulk. But in th...
متن کاملco-solutions and inheritance of stability
We consider the dynamics of semiflows of patterns on unbounded domains that are equivariant under a noncompact group action. We exploit the unbounded nature of the domain in a setting where there is a strong ‘global’ norm and a weak ‘local’ norm. Relative equilibria whose group orbits are closed manifolds for a compact group action need not be closed in a noncompact setting; the closure of a gr...
متن کاملStable Expression of Recombinant RhD Antigen Isolated from Cord Blood in K562 Cell Line
Background: The Rh antigens are expressed as parts of a protein complex in the RBC membrane. This complex is a tetramer, consisting of two molecules of RhAG and two molecules of Rh proteins. To express RhD in RBC membrane, expression of RhAG is essential. This co-expression only occurs in the erythroid lineage. K562 cell line has an erythroid lineage. Materials and Methods: Cord blood was used ...
