An international team in which a UPM researcher is involved has shown that it is possible to mechanically destroy cancer cells by rotating magnetic nanoparticles attached to them in elongated aggregates.
In many ways, magnets are still mysterious. They get their (often powerful) effects from the microscopic interactions of individual electrons, and from the interplay between their collective behavior at different scales. But if you can’t move these electrons around to study how factors like symmetry impact the larger-scale magnetic effects, what can you do instead?
Nanodiamonds are synthetic industrial diamonds that measure only a few nanometers. Recently, nanodiamonds have attracted significant attention due to their ability to carry out targeted delivery of cancer drugs and vaccines, and for other applications. To date, there have been limited possibilities for imaging nanodiamonds.
An innovative ultra-thin multilayer film has been developed by a research team headed by Associate Professor Yang Hyunsoo at the Department of Electrical and Computer Engineering of the Faculty of Engineering at the National University of Singapore (NUS).
A thin nanomaterial that has superconducting properties has been developed by a team of experimental physicists headed by Professor Uwe Hartmann from Saarland University.
If only one atom or small molecule was necessary for a single unit of data (a zero or a one as in binary digital technology), enormous volumes of data could be stored in the smallest amount of space.
Although they sound like a recent discovery, nanoparticles have been in use for centuries. For instance, the famous Lycurgus cup, crafted by 4th century Roman artisans, features dichroic glass, with silver and gold nanoparticles scattered throughout, giving the cup a red appearance when illuminated from behind and a green appearance when light is shining on it from the front.
From compasses used in ancient overseas navigation to electrical motors, sensors, and actuators in cars, magnetic materials have been a mainstay throughout human history.
As metals possess a large density of electrons, the wave nature of electrons can only be viewed if metallic wires measuring a few atoms in width are created.
Researchers at Johannes Gutenberg University Mainz (JGU) and the Massachusetts Institute of Technology (MIT) have made another important breakthrough in the field of future magnetic storage devices.
