Special Issue Information

Dear Colleagues,

Molecular dimensions are obviously well beyond the resolution of standard or even state-of-the-art lithographic techniques. This fact means that, in order to fabricate true nanoscale molecular electronics circuits, the molecules themselves represent just one part of the game (1st cycle). Another aspect involves coming up with fabrication methodologies for nanoscale construction that do not rely on lithographic processing. The only obvious alternative is chemical assembly by chemical reaction at the nanoscale, and its use in electronic manufacture opens up a third set of issues, namely, which molecules and materials are consistent with both chemical assembly and electronic circuitry? How the energy can be transferred from the molecule to the nanomaterial (2 cycle)? Finally, it is necessary to interface whatever nanoscale architectures are fabricated with the outside world, indicating the need for some structure that can interface (or multiplex) large numbers of molecular electronics devices with small numbers of wires (3 cycle). This component of the molecular optoelectronic circuit represents serious and fundamental scientific challenges, to the extent that the collective task appears daunting indeed. As with any chemical problem, it is important to know what to make, and so we will first rationalize our approach to devices within the context of molecular surfaces.

A New Interaction Force Model of Gold Nanorods Derived by Molecular Dynamics Simulation
Nanomaterials 2020, 10(7), 1293; https://doi.org/10.3390/nano10071293 - 01 Jul 2020
Abstract

Interactions between nanoparticles is one of the key factors governing their assembly for ordered structures. Understanding such interactions between non-spherical nanoparticles and developing a quantitative force model are critical to achieving the ordered structures for various applications. In the present study, the non-contact interactions of two identical gold nanorods (AuNRs) with different aspect ratios have been studied by molecular dynamics simulation. A new interaction potential and force model for two nanorods approaching side-by-side has been proposed as a function of particle surface separation and their relative orientation. In addition, the interaction potentials of two nanorods approaching in other typical orientation configurations (i.e., crossed, head-to-head and head-to-side) have also been investigated.

Recently, SiO2 has attracted wide attention in lithium-ion batteries owing to its high theoretical capacity and low cost. However, the utilization of SiO2 is impeded by the enormous volume expansion and low electric conductivity. Although constructing SiO2/carbon composite can significantly enhance the electrochemical performance, the skillful preparation of the well-defined SiO2/carbon composite is still a remaining challenge. Here, a facile strategy of in situ coating of polydopamine is applied to synthesis of a series of core-shell structured SiO2@carbon composite nanorods with different thicknesses of carbon shells. The carbon shell uniformly coated on the surface of SiO2 nanorods significantly suppresses the volume expansion to some extent, as well as improves the electric conductivity of SiO2. Therefore, the composite nanorods exhibit a remarkable electrochemical performance as the electrode materials of lithium-ion batteries. For instance, a high and stable reversible capacity at a current density of 100 mA g−1 reaches 690 mAh g−1 and a capacity of 344.9 mAh g−1 can be achieved even at the high current density of 1000 mA g−1. In addition, excellent capacity retention reaches 95% over 100 cycles. These SiO2@carbon composite nanorods with decent electrochemical performances hold great potential for applications in lithium-ion batteries. Full article
