With the light-emitting diode (LED) technology providing flexibility in spectral design, it is now possible to tune lighting's circadian and visual effects to suit the uses of different built environments.
For example, it should be possible to tune lights to give out a dose of near-violet light that would have antiseptic-like qualities, he adds.
By combining things like BioZen sensors and Definity lights in the future, the body could send signals to tune lights for our bodies' needs making us more productive and healthy.
At LCLS, researchers used pulses of specially tuned light to change the magnetic properties of a multiferroic material, and then used the ultrafast X-ray pulses to show that the atomic-scale magnetic structure can be directly manipulated in less than a trillionth of a second.
Thin channels are bored through the material, along which the chemical components of a medication can be pumped; the redirected, carefully tuned light sets off the reaction.
Phillips is also offering data-gathering connectivity in both its health care and lighting products, hoping to boost the efficiency of things like a patient's medication adherence, or tuning lights to compliment the amount of available sunlight.
Simon's fruit-fly protocol, for instance, demands that various minutiae be precisely tuned — lighting, temperature, humidity, and even whether you've cut new vials from their plastic bags far enough in advance to let out the stale air.
It has on-screen touch features that enable users to control the focus and to fine-tune lighting.
It confirms that coupling TiO2 with Fe2O3 and CdS can effectively tune the light absorption property to visible light region.
Photocatalytic disinfection was performed using a solar simulator (Newport) calibrated at air mass 1.5G (100 mW cm 2) as the light source and a UVF (Clarex) and red-pass filter (Clarex NIR-70) to tune the light spectrum.
