Smart Windows Use Iron Nanoparticles to Harvest Heat
Posted by Shailesh Prasad in categories: internet, nanotechnology, particle physics
Many of the previously dumb devices in our homes are getting smarter with the advent of internet-connected lights, thermostats, and more. Surely the windows can’t be smart, can they? A team of engineers from the German Friedrich-Schiller University Jena have created just that — a smart window that can alter its opacity and harvest energy from the sun’s rays.
There have been a number of “smart” electrochromatic window designs over the years, but these are mostly aimed at changing tint or opacity only. The windows designed by Friedrich-Schiller University researchers are vastly more functional. The so-called Large-Area Fluidic Windows (LaWin) design uses a fluid suspension of iron particles. This fluid is contained within the window in a series of long vertical channels. These “functional fluids” allow the window to change opacity, but also absorb and distribute heat.
The iron-infused fluid remains diffused until you switch the window on — the nanoparticles cloud up the channels and block light. When you flip the switch, magnets drag the nanoparticles out of the liquid to make the window fully transparent. When the magnet is switched off, the nanoparticles are resuspended to darken the panel. In general, the more nanoparticles you add, the darker the window becomes. You can even completely black it out with enough iron.

Better than holograms: A new 3D projection into thin air
Posted by Genevieve Klien in categories: holograms, particle physics, space
One of the enduring sci-fi moments of the big screen—R2-D2 beaming a 3D image of Princess Leia into thin air in “Star Wars”—is closer to reality thanks to the smallest of screens: dust-like particles.
Scientists have figured out how to manipulate nearly unseen specks in the air and use them to create 3D images that are more realistic and clearer than holograms, according to a study in Wednesday’s journal Nature. The study’s lead author, Daniel Smalley, said the new technology is “printing something in space, just erasing it very quickly.”

Tiny implant opens way to deliver drugs deep into the brain
Posted by Nancie Hunter in categories: biotech/medical, engineering, neuroscience
WASHINGTON — Scientists have created a hair-thin implant that can drip medications deep into the brain by remote control and with pinpoint precision.
Tested only in animals so far, if the device pans out it could mark a new approach to treating brain diseases — potentially reducing side effects by targeting only the hard-to-reach circuits that need care.
“You could deliver things right to where you want, no matter the disease,” said Robert Langer, a professor at the Massachusetts Institute of Technology whose biomedical engineering team reported the research Wednesday.
