Journal ArticleDOI
Origin of the magic numbers of water clusters with an excess electron
TL;DR: As the magic number clusters have significant positive adiabatic electron affinities, their abundant distributions in atmosphere could play a significant role in atmospheric thermodynamics.
Journal ArticleDOI
Anthracene derivatives bearing two urea groups as fluorescent receptors for anions
Sook Kyung Kim,N. Jiten Singh,Soo Jeong Kim,K.M.K. Swamy,Seunghee Kim,Keun-Hyeung Lee,Kwang S. Kim,Juyoung Yoon +7 more
TL;DR: In this article, comparative studies were carried out on the anion bindings of pyrophosphate, H2PO4−, and dicarboxylates to the anthracene derivatives bearing two urea groups on the 1,8 and 9,10-positions as fluorescent chemosensors for anions.
Journal ArticleDOI
Ab initio molecular dynamics of liquid water using embedded-fragment second-order many-body perturbation theory towards its accurate property prediction.
TL;DR: Structural, dynamical, and response properties of liquid water calculated by ab initio molecular dynamics using the embedded-fragment spin-component-scaled second-order many-body perturbation method with the aug-cc-pVDZ basis set are presented.
Journal ArticleDOI
Gap Opening of Graphene by Dual FeCl3-Acceptor and K-Donor Doping
TL;DR: In this paper, the authors employed the first-principles method taking into account van der Waals interaction to make a reasonably wide band gap in graphene, which is accomplished with bilayer graphene (BLG) dual-doped with FeCl3-acceptor and K-donor.

TL;DR: An extremely stable graphene electrode doped with macromolecular acid (perfluorinated polymeric sulfonic acid (PFSA)) as a p-type dopant provides not only ultra-high ambient stability for a very long time but also high chemical/thermal stability, which have been unattainable by doping with conventional small-molecules.
