A team at the University of Groningen has demonstrated a way to switch off antibiotic agents after just a few hours using warmth or sunlight.
or exposed to sunlight, they reverted to the Z-form, which is all but useless as an antibiotic.
Flower power, a device due to be launched towards the end of this year by Paris-based wireless tech company Parrot, measures sunlight, soil moisture, temperature and nutrient levels in plants,
and whether they should be moved to change sunlight levels. Flower power and related technologies could be vital in developing countries with dry climates.
The process involves single axis tracking concentrating collectors that essentially orient panels towards the sunlight.
#From sunlight to jet fuel: EU project makes first'solar'kerosene An EU-funded research project called SOLAR-JET has produced the world's first'solar'jet fuel from water and carbon dioxide (CO2), a promising technology for a better
using simulated sunlight. However, the results give hope that in future any liquid hydrocarbon fuels could be produced from sunlight
CO2 and water. The process In a first step concentrated light-simulating sunlight-was used to convert carbon dioxide
and water to synthesis gas (syngas) in a high-temperature solar reactor containing metal-oxide based materials developed at ETH Zürich.
and his team to absorb specific nonvisible wavelengths of sunlight. e can tune these materials to pick up just the ultraviolet
That is roughly the same efficiency at which the best commercially available solar cells convert sunlight into electricity.
#Panasonic#s new technology purifies water with sunlight and photocatalysts Drinking clean water is something that many people in the world can't take for granted as they rely on polluted sources
The company recently presented a system that uses sunlight and photocatalysts to purify polluted water at a high reaction rate to improve access to clean water where it's needed.
##But the maximum radio frequency intensity of the transmission##is only one-fourth that of sunlight,##according to former NASA wireless power transmission engineer Richard Dickinson.
#New LED light technology sheds light on the future of food LED growing lights, delivering sunlight whatever the weather.
Plants typically make use of only about 10 percent of the sunlight available to them,
#Toward a low-cost'artificial leaf'that produces clean hydrogen fuel For years scientists have been pursuing artificial leaf technology a green approach to making hydrogen fuel that copies plants'ability to convert sunlight into a form of energy they can use.
Peidong Yang Bin Liu and colleagues note that harnessing sunlight to split water and harvest hydrogen is one of the most intriguing ways to achieve clean energy.
and exposed to sunlight produces hydrogen gas. The scientists say that the technique could allow their technology to be scaled up at low cost.
Professor Evans and his team have all of the membrane proteins required to construct a fully working mimic of the way plants capture sunlight.
Researchers have known long that some single-celled organisms use a protein called bacteriorhodopsin (br) to absorb sunlight
If the researchers wanted to power their generators with sunlight, they'd need to improve on that.
#Urban vegetable garden system with LED lighting Keystone Technology LED vegetable garden system is a cultivation system for indoor plant factories that uses LED lighting instead of sunlight.
and does not have the coarse quality of lettuce grown in sunlight. Because it is softer it is a vegetable that is easy to eat even for elderly people.
and polyphenols than with vegetables grown in sunlight. ith this system there will be differences in production capacity depending on the shape of the plant.
whereas waves in natural sunlight vibrate in all directions. Manipulating the polarization of light is essential for the operation of advanced microscopes, cameras and displays;
Further field tests are necessary to see how the nano-dispensers perform in sunlight varying temperatures and humidity levels.
HILLS AND POTHOLESMANY of these types of flexible electronic devices will rely on thin films of organic materials that catch sunlight
which plants use the energy in sunlight to synthesize carbohydrates from carbon dioxide and water. However
"When sunlight is absorbed, photo-excited electron? hole pairs are generated in the silicon and titanium oxide nanowires,
the Berkeley team achieved a solar energy conversion efficiency of up to 0. 38-percent for about 200 hours under simulated sunlight,
under the sunlight, a small portion of solar energy(<1 percent) captured by chlorophyll is emitted as fluorescence.

The CU-Boulder invention consists of eight parabolic mirrors that focus concentrated sunlight to a spot no larger than a postage stamp on a quartz-glass rod connected to eight bundles of fiber-optic cables each consisting of thousands of intertwined fused
That finding dispels concerns that the genetic material will quickly degrade in rain and sunlight. In the proof-of-principle study researchers wanted to answer
A few feet below the surface, plenty of sunlight still filters in, the temperature is kept at a stable 25°C (77°F) by the sea,
which received Lux Awards 2014 Light source Innovation of the Year, can fill a room ceiling mimicking sunlight from different latitudes, from the equator to Northern europe.
The key to its success in replicating a sunny sky uses nanostructured materials to scatter light from LEDS in the same way tiny particles scatter sunlight in the atmosphere so-called Rayleigh scattering.
and they are sensitive to alkaline and sunlight, and they have strength limitations. According to Amir Behzadnia, one of the researchers, this study was carried out aiming to improve the properties of woolen products through special finishing process,
Water splitting combines sunlight and water in a chemical reaction in order to harvest clean hydrogen energy. By smoothing the surface of hematite,
iodide and methylammonium could convert sunlight into electricity with an efficiency of 3. 8 percent.
Sunlight to electricity Solar cells work by converting photons of sunlight into an electric current that moves between two electrodes.
a finding that dispels previous concerns that the genetic material would quickly degrade in rain and sunlight.
