A nanotube is a tubular particle made out of an extensive number of carbon atoms. Nanotubes having wide range of application in various fields such as Photovoltaic cells, targeted drug delivery, automobile industries, aerospace so on.
Now as per the recent studies, Researchers state that the weak van der Waals forces between the inner surface of the nanotube and the water molecules are strong enough to snap the oxygen and hydrogen atoms into place.
In the case of a two-dimensional ice, the molecules freeze regardless of the temperature and research provides valuable insight on ways to leverage atomic interactions between nanotubes and water molecules to fabricate nanochannels and energy-storing nanocapacitors.
Scientists built molecular models of carbon and boron nitride nanotubes with adjustable widths. They found boron nitride is best at obliging the state of water when the nanotubes are 10.5 angstroms wide.
The scientists definitely realized that hydrogen particles in firmly bound water go up against intriguing basic properties. Ongoing tests likewise demonstrated solid confirmation for the arrangement of nanotube ice and incited the analysts to fabricate thickness utilitarian hypothesis models to dissect the powers dependable.
When the water molecules are about 3 angstroms were modeled, inside carbon and boron nitride nanotubes of various chiralities and between 8 and 12 angstroms in diameter. They found that nanotubes in the middle diameters had the most effect on the balance between sub-atomic collaborations and van der Waals pressure that incited the change from a square water tube to ice.
If the nanotube is too small and only fit one water molecule, then the water keeps its amorphous shape. Van der Waals force starts to push water molecules into designed square shapes at the range of about 8 angstroms. Research shows that strongest interactions were found in boron nitride nanotubes due to the particular polarization of their atoms.
The nanotube ice could find use in molecular machines or as nanoscale capillaries, or foster ways to deliver a few molecules of water or sequestered drugs to targeted cells, like a nanoscale syringe.
