QCD Glueball Masses from AdS-6 Black Hole Description
By using the generalized version of gauge/gravity correspondence, we study
the mass spectra of several typical QCD glueballs in the framework of
AdS black hole metric of Einstein gravity theory. The obtained glueball
mass spectra are numerically in agreement with those from the AdS
black hole metric of the 11-dimensional supergravity.Comment: 10 pages, references updated and minor change
Density functional analysis of gaseous molecules adsorbed on metal ion/defective nano-sheet graphene
[[abstract]]Density functional theory was applied to calculate the adsorption property of metal/hexa-vacancy defective graphene (denoted as HDG-M, M: Fe2+, Co2+, Ni2+, Cu2+ and Zn2+) with O- and N-dopants. We investigate the adsorption properties of these complexes between gaseous molecules and HDG-M. Our results show that HDG-Cu has a high selectivity for O2, but HDG-Fe has a good ability to capture many gases such as CO, NO and O2. Our calculations could provide useful information for designing new graphene-based adsorbents to remove undesired gases, which may poison the metal catalysts in reaction processes.[[notice]]補æ£å®Œ
