Blackening it allows it to absorb light throughout a broad spectrum, making it far more effective.
They absorb light, do their photothermal task and destroy those local cells, and they would eventually leave the body through the liver.
They absorb light that would otherwise be picked up by lone chlorophyll molecules, thus preventing damage during the period of nutrient recovery.
According to scientists from a smattering of institutions, the atomic-scale chickenwire material has the ability to absorb light effectively -- much like a sponge -- over a broad range of wavelengths.
In order to see light, the eye must absorb it, but in order for a person to be invisible, the body must not absorb any light.
Blackening copper allows it to absorb more light and heat, increasing the range of uses for the metal.
The primary function of oxybenzone is to absorb ultraviolet light, but some research shows oxybenzone can be absorbed through the skin.
They absorb the light and convert light to heat with incredible efficiency.
The technology has an unprecedented ability to absorb external light reflections through an increased wedge depth, which leads to "blacker" blacks, more-realistic pictures and higher color contrast.
ENGADGET: Samsung details pricing and availability for its 2012 Smart TV lineup
Light at a specific wavelength is beamed into the brain, and the oxygen present will absorb some of that light.
Though the carbon nanotubes absorb infra-red light, they are almost totally transparent to the visible variety.
The first nanoshells made by Dr West are designed to absorb infra-red light.
The atoms in the gas will absorb certain colours of light, each of which corresponds to a particular wavelength.
Dark-skinned people living in northern locales are most at risk, as they absorb sunlight more poorly than light-skinned folks.
The uppermost parts of its thick cloud layer mysteriously absorb half of the ultraviolet light received by the planet.
Light-colored "cool roofs" that reflect light rather than absorb it can cut cooling costs by as much as 40%, the group says.
Manhattan-based Lazare Kaplan has been peddling what the industry calls "ideal cut" stones--which absorb and disperse visibly more light than most finished diamonds--since the mid-1980s.
By controlling the inner and outer thickness of this metallic shell we can control the wavelength of light that this nanoparticle will absorb.
So what we want to do is fine-tune that special characteristic of the light so it shines back and it doesn't absorb into the material and cause damage.
This ingenious technique which won its inventors, one of whom was Steven Chu, now America's energy secretary, a Nobel prize works by bombarding an object with laser light at a frequency just below that which it would readily absorb and re-emit if it were stationary.
These wavelengths of light have a significant impact on the thermosphere, where air molecules absorb their energy and the reradiate it in the form of infrared energy.
