Comment on 3D Penrose Tiling of the Icosahedral Quasicrystalline Phase

TL;DR

This paper critiques a recent claim that 3D Penrose tiling explains the icosahedral quasicrystalline phase, arguing that the proposed twinning scheme lacks validity despite its novelty.

Contribution

It provides a critical analysis of a recent alternative explanation for the quasicrystalline phase, challenging its validity.

Findings

The proposed twinning scheme is invalid.

The paper supports the traditional understanding of quasicrystalline structure.

It emphasizes the importance of established models over novel but unvalidated schemes.

Abstract

A recent arXiv contribution makes the case that the quasicrystallinephase is due to twinning, albeit with a different twinning scheme than thatpresented by Pauling. It appears to us that this approach, though novel, hasno validity.
