Building tailor-made DNA nanotubes step by step
Researchers at McGill University have developed a new, low-cost method to build DNA nanotubes block by block - a breakthrough that could help pave the way for scaffolds made from DNA strands to be used in ...
Scientists go to great lengths to extend superlow friction
Penta-graphene, a new structural variant of carbon, discovered
Researchers at Virginia Commonwealth University and universities in China and Japan have discovered a new structural variant of carbon called "penta-graphene" - a very thin sheet of pure carbon that has a ...
Gold nanotubes launch a three-pronged attack on cancer cells
Scientists have shown that gold nanotubes have many applications in fighting cancer: internal nanoprobes for high-resolution imaging; drug delivery vehicles; and agents for destroying cancer cells.
Novel approach for high performance field emission electron sources
Enhancing the electron emission of multiwall carbon nanotubes (MWCNT) is key for applications ranging from cold cathodes used in high-resolution electron microscopes to portable X-ray imaging systems. In a paper recently ...
Nanotubes self-organize and wiggle: evolution of a non-equilibrium system demonstrates maximum entropy production
The second law of thermodynamics tells us that all systems evolve toward a state of maximum entropy, wherein all energy is dissipated as heat, and no available energy remains to do work. Since the mid-20th ...
An unusual form of carbon ring structure identified in a family of doughnut-like macrostructures
The source of the peculiar stability of the structures forming carbon nanotubes has been established by researchers from the RIKEN Elements Chemistry Laboratory.
Better batteries inspired by lowly snail shells
Scientists are using biology to improve the properties of lithium ion batteries. Researchers at the University of Maryland, Baltimore County (UMBC) have isolated a peptide, a type of biological molecule, ...
Understanding the reinforcing ability of carbon nanotubes
A paper in the journal Science and Technology of Advanced Materials explores what is preventing the reinforcing ability of carbon nanotubes from being used in a ceramic matrix.
