A nanoparticle shaped like a spiky ball, with magnetic properties, has been uncovered in a new method of synthesising carbon nanotubes by physicists at Queen Mary University of London and the University of Kent.
Making large quantities of reliable, inexpensive nanoparticles for batteries, solar cells, catalysts and other energy applications has proven challenging due to manufacturing limits. A Cornell research team is working to improve such processes with a $1.5 million National Science Foundation (NSF) grant to support scalable nanomanufacturing and device integration.
Researchers have recently developed a method by which different crystals can be separated by their density in a magnetic field. They have now demonstrated the extraordinary efficiency of separation through 'magnetic levitation'.
A team of researchers from Uppsala University in Sweden has designed a microplasma source capable of exciting matter in a controlled, efficient way. This miniature device may find use in a wide range of applications in harsh environments, but can also help revolutionize archaeology.
