The nanoparticles were discovered accidentally on the rough surfaces of a reactor designed to grow carbon nanotubes A nanoparticle shaped like a spiky ball, with magnetic properties, has bee... Read more
Wonder material graphene can be made magnetic and its magnetism switched on and off at the press of a button, opening a new avenue towards electronics with very low energy consumption. In a... Read more
New synthetic nanoparticle could disinfect, depollute, and desalinate contaminated water and then get removed magnetically Among its many talents, silver is an antibiotic. Titanium dioxide i... Read more
The MIT researchers’ work could lead to robotic systems that can be dynamically reconfigured to do many different jobs rather than repeating a fixed function, and that can be produced much m... Read more
The idea behind it is over 100 years old DYSPROSIUM and neodymium are not exactly the best-known elements in the periodic table, but for makers of high-end electric motors they have become v... Read more
The goal is to make new magnet alloys from recycled rare earths Recycling keeps paper, plastics, and even jeans out of landfills. Could recycling rare-earth magnets do the same? Perhaps, if... Read more
MIT researchers devise a surprisingly simple but effective method for magnetically separating oil and water. MIT researchers have developed a new technique for magnetically separating oil an... Read more
We have developed a new material with similar properties without those exotic elements Northeastern University researchers have designed a super-strong magnetic material that may revolutioni... Read more
