Inspired by the highly efficient water transport presented in hourglass-shaped aquaporin channels, molecular dynamics simulations were conducted to study water desalination in carbon nanocones (CNCs). Their desalination performance (salt rejection, water flow) depends on the cone size, angle, and flow direction (nonequilibrium). Free energy calculations reveal that ultrasmall CNCs with apex angles...
The ability to scale up the production of chemically modified forms of graphene has led to intense interest in the manufacture and commercialization of graphene-based materials. Free-standing film-like materials comprised of stacked and overlapped platelets of graphene oxide (G-O) or thermally and electrically conductive reduced graphene oxide (rG-O) are potentially useful in various applications...
Design and fabrication of functional carbon nanostructures is a challenging but meaningful mission for scientists to propel the development of nanotechnology, such as nanopharmacology, nanobiology and nanofluidic manipulation. In order to fabricate the carbon nanostructures, using forced-field-based molecular dynamics simulations, we proposed a feasible method to obtain the carbon nanostructures through...
A model describing the effect of true density and porosity on the electrical resistivity of carbon materials is developed based on ideal fluid mechanics. The modeling results are in good agreement with experimental data with a largest deviation of 2%. Open porosity has a greater effect on resistivity than closed porosity. An increase of open porosity by 40% leads to a resistivity increase by 250%...
Top-down process, comprising lithography and plasma etching is widely used in very-large-scale integration due to its scalability, has the greatest potential to fabricate graphene nanoribbon based nanoelectronic devices for large-scale intergraded circuits. However, conventional plasma etching inevitably introduces plenty of damage or defects to the etched materials, which drastically degrades the...
