Review on strategic technology of dense connection for the future mobile network by Zhihong QIAN, Lin XIAO, Xue WANG

“…Based on reviews of the work regarding dense connection, the strategic technologies for dense connection in the upcoming future mobile communication were illuminated.The state of the art of dense connection, including network architecture and related technologies, the transmission technology of dense connection, and the access technology of dense connection were analyzed.A flexible access network structure with verity of connection forms coexisting was proposed.Aiming at the asymmetry of uplink and downlink coverage and considering the QoS requirements of users, a dense terminal access scheme based on the uplink-and-downlink-separated network architecture was proposed.The necessity of the three-dimensional network architecture and the integration of communication and computing to meet the needs of large-scale networking and dense connection were illuminated.Based on technologies such as terahertz and block chain, the future strategic exploratory trends such as the upward extension of frequency bands and the sharing of spectrum resources were discussed and prospected.…”

Adsorption of Phenols from Different Solvents on Graphene: Semi-Empirical Quantum Mechanical Calculations by Pablo Húmpola, Héctor S. Odetti, Alberto G. Albesa, José L. Vicente

“…Our results raise doubts that phenol is primarily adsorbed in flat position on the graphene layers, and consequently whether the adsorption forces are controlled by π–π dispersion interactions between the aromatic ring of phenol and the graphene layer structure. Based on the results of quantum mechanical calculations (carried out through various approaches), we conclude that neither surface oxidation nor the presence of a polarizable solvent is consistent with the claim that π–π interactions are dominant in the adsorption of phenolic compounds on graphite.…”
