Researchers have observed the quantum regime in the interaction between nano-sized spheres of gold, thanks to the change of color of the gap between these particles when they are at distances of less than one nanometer.
They have literally 'seen' a quantum kiss between nanoparticles.
New single laser devices that are the size of a virus particle can also operate at room temperature. These plasmonic nanolasers could be readily integrated into silicon-based photonic devices, all-optical circuits and nanoscale biosensors.
We're going to need ultra-fast data processing and ultra-dense information storage by the time Halo 8 comes to a holodeck near you, so reducing the size of photonic and electronic elements is critical.
If one beam travels a fixed length and another travels an extra distance or in some other slightly different way, the two light beams overlap and interfere when they meet up, creating an interference pattern that scientists inspect to obtain highly precise measurements.
A recent placebo-controlled study showed evidence of trans-cranial bright light's effect to brain functions when administered through the ear. Bright light stimulation was found to increase activity in brain areas related to processing of visual sensory information and tactile stimuli. The findings are the first ever published scientific article about functional modulation of the brain with bright light delivered to the brain through the ears.
Your cay may soon have a new dashboard, one made of a flexible plastic and oxide layer that could be integrated into the car front window to give the driver direct information
The MULTIFLEXIOXIDES project is designed to develop new cost-efficient, long lasting, light, flexible and transparent devices (can anything be all of those? Only in academia) which can display information directly on the windshield. This is possible using small glass pads with a transparent substrate of nano-sized flexible oxides, which act as a basis for organic LEDs (light-emitting diodes).
A new imaging system uses walls, doors or floors as 'mirrors' to gather information about scenes that it can't see, even though those objects are not reflective.
Yes, it could ultimately lead to imaging systems that allow emergency responders to evaluate dangerous environments or vehicle navigation systems that can negotiate blind turns, among other applications, but spying on people sounds like more fun.
A new high-precision 3-D printer at TU Vienna is orders of magnitude faster than similar devices and opens up completely new areas of application, such as in medicine. "Two-photon lithography" means tiny structures on a nanometer scale can be fabricated quicker than ever.
Their 3-D printer uses a liquid resin, which is hardened at precisely the correct spots by a focused laser beam. The focal point of the laser beam is guided through the resin by movable mirrors and leaves behind a polymerized line of solid polymer, just a few hundred nanometers wide. This high resolution enables the creation of intricately structured sculptures as tiny as a grain of sand.
CMOS Imaging sensors
are the sensor of choice for most consumer digital cameras. They tend to be cheap, low power, compatible with the fabrication equipment that much of modern digital electronics is manufactured on, and other than the very early generations fairly high quality.
Canon EOS cameras became the defacto standard for astrophotography due to low noise and direct access to uncompressed RAW image formats.
We've done articles on rainbows, and double rainbows and even showed you how to make a rainbow appear for that special someone
- but have you ever seen a triple rainbow?
Optofluidic solar lighting systems could mean a real boost in solar energy - they capture sunlight from a roof using a light concentrating system that follows the sun's path by changing the angle of the water's refraction, and then distribute the sunlight throughout the building through light pipes or fiber optic cables to the ceilings of office spaces, indoor solar panels, or even microfluidic air filters.
