Impact of Graphene Quantum Dot Edge Morphologies on Their Optical Properties.
TL;DR: In this article , the optoelectronic properties of functionalized graphene quantum dots (GQDs) have been explored by simulating electronic structure of three different shapes of GQDs containing exclusively zigzag or armchair edges in both pristine and functionalized forms.

Observation of breather and soliton in a substituted polythiophene with a degenerate ground state
Takayoshi Kobayashi,Juan Du,Wei Feng,Katsumi Yoshino,Sergei Tretiak,Avadh Saxena,Alan R. Bishop +6 more
TL;DR: In this paper, the ultrafast dynamics of a unique polythiophene derivative that has a degenerate ground state due to an alternating benzenoid-quinoid resonance were investigated using a sub-5-fs pulse laser and a detection system composed of a polychromator and a multichannel lock-in amplifier.
