A new vortex electric field with the potential to enhance future electronic, magnetic and optical devices has been observed by researchers from City University of Hong Kong (CityUHK) and local ...

Vortex is ubiquitous in nature including spiral arms of galaxy, planet rotation, hurricane (tornado). A vortex is a typical and well-known magnetic domain structure in dimensionally confined ...

Optical vortex plays an important role in a variety of fields, such as particle tweezing, quantum communication, astrophysics, and microscopy. Especially, the application of optical vortex has been ...

Sandia researchers have developed a process that can mix tiny volumes of liquid, even in complicated spaces. Researchers currently use all types of processes to try and create mixing, with only "mixed ...
