The fractional strong metric dimension in three graph products
Cong X. Kang, Ismael G. Yero, Eunjeong Yi
For any two distinct vertices and of a graph , let denote the set of vertices such that either lies on a geodesic or lies on an geode…
Lithium Adsorbtion on Polyacenes Zig-zag-edge Graphene Strips
Yenni P. Ortiz, Douglas J. Klein, Thomas H. Seligman
The effect of increased electron-density (from adsorbed Li atoms) in polyacenes and in nano-ribbons with zig-zag edge is discussed in terms of resonance theoretical considerations…
Tetrahedral Units: For Dodecahedral Super-Structures
Y. Ortiz, D. J. Klein, J. F. Liebman
Different novel organic-chemical possibilities for tetrahedral building units are considered, with attention to their utility in constructing different super-structures. As a repre…
Chains of benzenes with lithium-atom adsorption: Vibrations and spontaneous symmetry breaking
Yenni P. Ortiz, Thomas Stegmann, Douglas J. Klein +1
We study effects of different configurations of adsorbates on the vibrational modes as well as symmetries of polyacenes and poly-p-phenylenes focusing on lithium atom adsorption. W…
