#Greased Lightning! NASA Drone Advances Unmanned Craft A huge, 10-engine drone dubbed"Greased Lightning"successfully completed a series of flight tests recently,
In graphene, infrared light launches ripples through the electrons at the surface of this metallike material called surface plasmon polaritons that the researchers were able to control using a simple electrical circuit.
Infrared light can also launch polaritons within a different type of two-dimensional crystal called hexagonal boron nitride.
As a result, this human-made material manipulates electromagnetic radiation-light-in ways never observed in natural materials.

They showed how a single nanoresonator can manipulate light to cast a very large"reflection."
"Making an object look 10,000 times larger than its physical size has lots of implications in technologies related to light,
Much like sound, light can resonate, amplifying itself as the surrounding environment manipulates the physical properties of its wave energy.
which the wavelength of light is much larger than in a vacuum, which allows light waves to resonate more powerfully.
and then scatters the light over a very large area, harnessing its output for imaging applications that make microscopic particles appear huge."
In addition, Yu envisions simply letting the resonator emit that energy in the form of infrared light toward the sky,
"This research opens up a new way to manipulate the flow of light, and could enable new technologies in light sensing and solar energy conversion,
using ultraviolet light. The end result is safe drinking water that also tastes good. Earlier this year, Wrights team won a grant from the United states Agency for International Development (USAID),
The movement of electrons caused by friction was able to generate enough energy to power the lights

and ultraviolet (UV LIGHT to quickly isolate and extract a variety of contaminants from soil and water.
Nanoparticles that lose their stability upon irradiation with light have been designed to extract endocrine disruptors, pesticides,
Brandl had synthesized previously polymers that could be cleaved apart by exposure to UV LIGHT. But he and Bertrand came to question their suitability for drug delivery,
since UV LIGHT can be damaging to tissue and cells, and doesn penetrate through the skin.
When they learned that UV LIGHT was used to disinfect water in certain treatment plants, they began to ask a different question. e thought
if they are already using UV LIGHT, maybe they could use our particles as well, Brandl says. hen we came up with the idea to use our particles to remove toxic chemicals, pollutants,
because we saw that the particles aggregate once you irradiate them with UV LIGHT. A trap for ater-fearingpollution The researchers synthesized polymers from polyethylene glycol,
But when exposed to UV LIGHT, the stabilizing outer shell of the particles is shed, and now nrichedby the pollutants they form larger aggregates that can then be removed through filtration, sedimentation,
#Living lasers made by injecting oil droplets into human cells Light fantastic (Image: Matja Humar and Seok Hyun Yun) Individual cells have been turned into tiny lasers. t actually super-easy,
Humar and his colleagues developed three ways to get cells to emit visible light. The first involved injecting each one with a tiny oil droplet,
Shining a light pulse on to the cavity excited the dye atoms into emitting light in a tightly focused beam.
#Boron Turns Graphene into Blue light Emitter FRANKFURT, Germany, July 14, 2015 Chemists at Goethe University Frankfurt have developed a new class of organic luminescent materials through the targeted introduction of boron
Data transmission via light could be the answer to the call for a faster and more energy efficient data flow on computer chips as well as between different board components.
Neither element is very efficient as a light source however. They are classed among the indirect semiconductors.
In contrast to direct semiconductors they emit mostly heat and only a little light when excited.
and manufactured a module enabling irradiation with UV-B light of a specific wavelength. In this particular case, LEDS emitting at a wavelength around 310 nm are used to stimulate health-promoting secondary metabolites in plants.
With these FBH tiny monolithic light sources on chip level, a compact SERDS measurement head that is only as small as a laser pointer was realized for the first time.

Silicon solar cells generate electricity by absorbing photons of visible and infrared light, while perovskite cells harvest only the visible part of the solar spectrum where the photons have more energy.
Colin Bailie, Stanford bsorbing the high-energy part of the spectrum allows perovskite solar cells to generate more power per photon of visible light than silicon cells,
or light it likely will degrade. We have a ways to go to show that perovskite solar cells are stable enough to last 25 years.
The friction was strong enough for the electrodes to harvest enough energy to power the lights,
and exposed it to ultraviolet light, which is found in the sun rays and breaks down many materials.
