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.

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.

New advancements in 3-D designs for neural tissue engineering

It is well known that neurological diseases and injuries pose some of the greatest challenges in modern medicine, with few if any options for effectively treating such diagnoses, but recent work suggests a unique approach for reconstructing damaged neural tissue. In an article published in the journal Neural Regeneration Research, several new designs for 3D tissue constructs are described for using stem cells grown on nanofiber scaffolding within a supportive hydrogel.

MIPT researchers put safety of magic anti-cancer bullet to test

A group of MIPT researchers together with their colleagues from Moscow, Nizhny Novgorod, Australia and the Netherlands have carried out the first systematic study analyzing the safety of so-called upconversion nanoparticles that may be used to treat skin cancer and other skin diseases. This study is one of the most important steps on the path to new, safe and effective methods to diagnose and treat cancer.
