Well scientists in the Bhavnagar University of Gujarat have done something very interesting... well it sounds interesting to a non-scientists anyways 🙂 They have trapped light in a "soup" of nano and micro particles! Physicists at the Bhavnagar University in Gujarat, India, have demonstrated how to trap and retrieve light using a soup of micro- and nano-sized magnetic spheres.1 The unusual fluid, they say, works at room temperature, holds photons for far longer than other systems, and can also be tuned with a magnet to store any wavelength of visible light. 'The discovery could pave the way for lab-on-a-chip devices for processing optical information,' Rasbindu Mehta, who led the team, told Chemistry World. Read more
