Iranian Scientists Produce Magnetic Recyclable Photocatalyst to Purify Polluted Water

Iranian researchers from University of Mohaqeq Ardabili used nanotechnology to produce a photocatalyst which can be used for purification of water.

The photocatalyst was made of non-toxic and eco-friendly materials and can be reused five times in the process. Results of the research can be used in water and wastewater purification industries.

Tunneling across a tiny gap:

Conduction and thermal radiation are two ways in which heat is transferred from one object to another: Conduction is the process by which heat flows between objects in physical contact, such as a pot of tea on a hot stove, while thermal radiation describes heat flow across large distances, such as heat emitted by the sun.

This illustration depicts phonons "tunneling" from one lattice of sodium chloride to another. New research shows that phonons can reach across a gap as small as a nanometer, “tunneling” from one material to another to enhance heat transport.

Future electronics based on carbon nanotubes: A team at the University of Illinois at Urbana-Champaign finds way to purify arrays of single-walled carbon nanotubes (SWCNTs), possibly providing a step toward post-silicon circuits and devices

The exceptional properties of tiny molecular cylinders known as carbon nanotubes have tantalized researchers for years because of the possibility they could serve as a successors to silicon in laying the logic for smaller, faster and cheaper electronic devices.
