Endohedral Functionalization of Metallicity-Sorted Single-Walled Carbon Nanotubes

Proceedings, 2020
We performed endohedral functionalization of high-purity metallicity-sorted semiconducting and metallic single-walled carbon nanotubes (SWCNTs) with a mean diameter of 1.4 nm with silver chloride (AgCl) by the method of capillary filling with the melt ...

Stability of FeVO₄-II under Pressure: A First-Principles Study

Crystals, 2022
In this work, we report first-principles calculations to study FeVO4 in the CrVO4-type (phase II) structure under pressure. Total-energy calculations were performed in order to analyze the structural parameters, the electronic, elastic, mechanical, and ...

Quantum Simulation of a 2D Quasicrystal with Cold Atoms

Crystals, 2016
We describe a way to obtain a two-dimensional quasiperiodic tiling with eight-fold symmetry using cold atoms. One can obtain a series of such optical tilings, related by scale transformations, for a series of specific values of the chemical potential of ...
