Sunlight-powered purifier could clean water for the
One-tenth of the world''s population lacks clean water. Now, researchers report they have developed a cheap solar still, which uses sunlight to purify dirty water up to four times faster than a
Science popularization of water-light needle: full analysis of
The water-light needle directly delivers hyaluronic acid to the dermis, solving the problem of skin water shortage from the root cause, and the effect is more direct and significant.
Stanford Develops Chiclet-Sized Device That Purifies
Researchers at SLAC National Accelerator Laboratory and Stanford University have developed a tiny, Chiclet-sized device that uses solar energy to
Solar-Powered Water Desalination | Science Project
MIT engineers built a solar-powered desalination system that produces large quantities of clean water despite variations in sunlight throughout
New solar technology could produce clean drinking
Now, researchers have developed a new material that speeds the process of evaporation, enabling a small solar still to provide all the drinking
Crookes radiometer
A gold light mill, only 100 nanometers in diameter, was built and illuminated by laser light that had been tuned. The possibility of doing this had been suggested by the Princeton physicist Richard Beth in 1936.
Solar bracket water light needle science popularization
When a water light needle is injected, the needle stimulates and damages the epidermis, opening the skin channel which involves destroying the skin self-protection barrier
SLAC, Stanford Gadget Grabs More Solar Energy to Disinfect Water
By harnessing a broad spectrum of sunlight, it works faster than devices that use only ultraviolet rays. (Jin Xie/Stanford University) This nanostructured device, about half the size of a
Solar still made of bubble wrap could purify water for
She found that a top layer of bubble wrap acted as an excellent insulator. So Chen and his student George Ni covered their solar still in bubble
