Carbon onions, which are made of concentric graphene spherical shells, are a potential solid lubricant similar to Tungstenite (WS2) nanoparticles having an onion-like structure. In addition, carbon onion nanoparticles are expected to have good prospects for other applications, such as the reinforcement of composite materials, magnetic storage media and wear-resistant materials.

Lithography is a critical enabling technology for manufacturing nanoscale devices and structures. Suppose nanolithography tools cost just a few thousand dollars a piece instead of a few million dollars. These cheap tools would wide open the fields of nanotechnology to practically every university and industry researcher interested in the field.

Building reliable interconnections between carbon nanotubes (CNTs) and external electrical and mechanical systems is an essential prerequisite to exploring the potential of CNTs in various domains. The formation of a stable and low-resistance ohmic contact between CNTs and electrodes contributes to speeding up the development of applications with CNTs in nanoelectronic devices with small size, fast speed and low power dissipation.
