When it comes to various advanced technical applications—for example, superconducting wires for magnetic resonance imaging—engineers aim to get rid of electrical resistance and its coexisting synthesis of heat to a considerable extent.
Experiments reveal micron-sized spheres coming together under the impact of a speedily spinning magnetic field.
An interdisciplinary team of researchers at the University of Massachusetts Amherst has developed a new group of electronic materials that may pave the way to a “green,” more sustainable future in biomedical and environmental sensing, say research leaders microbiologist Derek Lovley and polymer scientist Todd Emrick.
A new way to control the electronic and magnetic properties of molecules has been discovered by scientists from the Regional Centre of Advanced Technologies and Materials (RCPTM) at Palacký University, Olomouc, together with the colleagues from the Institute of Physics (FZU) of the Czech Academy of Science (CAS) and the Institute of Organic Chemistry and Biochemistry (IOCB) of the CAS.
Using pigments has drawbacks: industrial pigments are mostly toxic, colors can fade, & certain color effects are hard to produce.
Carrying out biomedical tasks in living systems using micro and nanomotors has gained significant interest of late. These motors can often be controlled remotely using various type of fields to study biomedical phenomenon.
A research team led by a scientist from the U.S. Department of Energy’s Ames Laboratory has demonstrated for the first time that the magnetic fields of bacterial cells and magnetic nano-objects in liquid can be studied at high resolution using electron microscopy.
Researchers from MIT and North Carolina State University have discovered a more simple method to deposit magnetic iron oxide, or magnetite, nanoparticles onto silica-coated gold nanorods, making multifunctional nanoparticles with useful optical and magnetic properties.
Since the late 60´s electronic gadgets have stored and transmitted information (bits) in 2D circuits. Recently, a team of researchers at the University of Cambridge have been able to cross this barrier by developing a nanoscale magnetic circuit that can move information along the three dimensions of space.
Magnets and magnetic occurrences underpin the huge majority of advanced data storage, and the measurement scales for research dedicated on magnetic behaviors continue to shrink with the rest of digital technology.
