Low Dimensional Materials

Graphene is a hexagonal lattice of carbon atoms that connect to form a single sheet in 2 dimensions.

Graphene oxide (GO) is a two-dimensional material with oxygen-functionalized surfaces, derived from graphite.

Hexagonal boron nitride (h-BN) has a layered structure. In a layer of h-BN, each boron atom is covalently bonded to three nitrogen atoms and vice versa.

The properties of bulk hexagonal boron nitride crystals differ from that of the monolayer material. The bulk exists as layered hexagonal lattice material similar to graphite.

Single-walled carbon nanotubes (SWCNTs) and multi-walled carbon nanotubes (MWCNTs) have some similarities and some key differences. Both materials are made from hexagonal lattices of carbon, specifically graphene sheets rolled up to form tubular structures. However, the nested structure of MWCNTs gives them distinct properties that differentiate them from SWCNTs.

Carbon nanotubes (CNTs) have unique properties such as high conductivity and strength. They have similar properties to another carbon allotrope known as graphene. This is due to the similarity in structure of 2D sheet-like graphene and 1D carbon nanotubes which are essentially cylindrical tubes of rolled up graphene.

There are multiple methods for producing carbon nanotubes (CNTs) and they usually involve gas phase processing. The three key methods are; chemical vapour deposition (CVD), laser ablation and arc discharge.

Carbon nanotubes (CNTs) and graphene are two ground-breaking nanomaterials composed entirely of carbon atoms. Both are allotropes of carbon where atoms are bonded in a hexagonal lattice.

Carbon nanotubes (CNTs), such as single-walled carbon nanotubes (SWCNT), have been tipped as one of the most exciting nanomaterials in the development of battery technology. The key properties of CNTs that make them ideal candidates as battery components is their high electron conductivity, high strength and lightweight nature.

The two main types of carbon nanotubes are single-walled carbon nanotubes (SWCNT) and multi-walled carbon nanotubes (MWCNT). Scientific research has led to the development of other types of carbon nanotubes with distinct features. Modifications to the chemistry and structure of carbon nanotubes have improved specific properties for various applications.

Tungsten disulfide (WS₂) exits in different forms, each with their own beneficial properties. Bulk WS₂ offers advantages such as exceptional lubricity and high thermal stability.

Graphene is a single layer of carbon atoms arranged in a hexagonal pattern, like a sheet of paper. Graphite, on the other hand, is made up of many layers of graphene stacked on top of each other, like a stack of paper.
