(GIST OF SCIENCE REPORTER) Goldene

(JUNE-2024)

Why researchers have created Goldene, asheet of gold that is only one atom thick.

Goldene is a former allotrope of gold that is two-dimensional and made up of a single layer of gold atoms arranged in a 2D structure.

The Function of Murakami’s Reagent

Precision during etc hing was important in order to ensure the successful fabrication of Goldene.
Etching Process: The titanium carbide layers were removed using a traditional Japanese method involving Murakami’s reagent.
Lack of light: Operations had to be carried out without any light present.

Classic challenge: Gold has a tendency to group together, posing a challenge in producing single-atom layers.
Earlier 2D Materials: Two-dimensional (2D) materials have been developed following the discovery of graphene in 2004, however, manufacturing thin metallic sheets faced challenges because metals have a tendency to create nano particles.

Transformation in the Electronics Industry: The ultra-thin and light weight qualities of Goldene could greatly decrease the gold required in electronics.
Catalysis: It shows potential as an effective catalyst since it is more cost-effective than thicker, three-dimensional gold.
Expansion to Different Metals: The method used to make goldene could also be modified to create thin sheets of other valuable metals such as iridium and platinum, broadening the potential uses.
