Water flow modeling through a graphene-based nanochannel: theory and simulation.

Understanding the behavior of water molecule transport through artificial nano-channels is essential in designing novel nanofluidic devices that could be used especially in nanofiltration processes. In this study, using nonequilibrium molecular dynamics (MD) simulations, we simulated the water flow through different graphene-based channels to investigate the influences of some key factors such as the channel thickness and applied pressure on the water flow. It was demonstrated that the water flow was enhanced by increasing the applied pressure and channel thickness.

CuO Nano-structures Prepared in Rosmarinus Officinalis Leaves Extract Medium: Efficient Catalysts for the Aqueous Media Preparation of Dihydropyrano[3, 2-c]chromene Derivatives.

CuO nano-structures were prepared in Rosmarinus Officinalis leaves extract medium via a green bio-chemical method and were used for the one-pot synthesis of dihydropyrano [3,2-c] chromene derivatives. This procedure is very simple and the products were synthesized in high to excellent yields.
