Short Note on Superconductivity at Ambient Temperature and Pressure in Silver Embedded Gold Nano-particles: A Goldsmith job ahead

TL;DR

This paper discusses recent claims of superconductivity at 235 K in silver-embedded gold nanoparticles, emphasizing the need for reproducible synthesis methods to confirm and explore this phenomenon further.

Contribution

It highlights the challenge of fabricating the material and encourages independent reproduction of the observed superconductivity in gold-silver nano-composites.

Findings

Superconductivity observed at around 235 K in experiments.

Low shielding fraction indicates partial superconductivity.

Reproducibility of results remains a challenge.

Abstract

Very recent observation of superconductivity in both transport (resistance versus temperature) and magnetization (Zero field cooled) at around 235 K has obviously raised many eyebrows. The experimental fraternity in particular is more thrilled. Although the results presented in the paper are clean and both transport and magnetization measurements do approve the observation of superconductivity to some extent (the shielding fraction is low), the problem is to synthesize or fabricate the material. This I name a goldsmith job, primarily because one has to deal with Gold and Silver nano particles combination/amalgamation/alloying or even who knows the inter-facial new phase, which could be superconducting. This short note is written in view to let the spark continues and the interesting work of ) authors is reproduced independently.
