TL;DR: In this paper, the structural properties of single-layer sheets, multilayer stacks, and single-walled nanotubes (SWNTs) of cadmium chalcogenides CdX (X = S, Se, Te) have been studied using ab initio density functional theory, along with spin-orbit coupling, van der Waals (vdW) interactions, and the GW approximation.

TL;DR: The origin of the miscibility between C(60) fullerene and a series of phenyl vinyl polymers has been investigated using a combination of wide-angle X-ray (WAXS) and neutron (WANS) scattering and density functional theory (DFT) computational modeling.

TL;DR: In this paper, the authors investigated the rate and mechanism for energy flow from high CH stretch and methyl group excited states in dimethylnitramine and showed that the energy transfer is rapid and irreversible.

TL;DR: In this paper, the authors investigate negative differential resistance (NDR) devices based on atomically precise graphene nanoribbons and propose a new device structure consisting of multiple short segments that enables high current by the alignment of electronic levels across the segments while enlarging the tunneling distance between the leads.

TL;DR: Current-voltage characterization shows a significant enhancement in short circuit current, suggesting the potential of these novel nanostructured buffer layers to replace the PEDOT:PSS buffer layer typically applied in traditional P3HT-PCBM solar cells.
