the residual limbs of the amputee are immersed in a tank of water one at a time, with a membrane material wrapped around them.
triggering the nanotubes to unzip into nanoribbons, with water as a byproduct. The experiments were duplicated by participating labs at Rice, at the Indian Institute of technology and at the Lebanese American University in Beirut.
so (this experiment) was very much a toe in the water for us, he said. The system is an internal BBC prototype,
which swell upon absorption of water and contract when they lose water. When billions of these spores were glued together on several plastic tapes called HYDRAS (hygroscopic-driven artificial muscles),
their movement was used to create energy that powered an engine which could run LED LIGHTS and even drive a miniature car!
and naturally occurring gradients near the surface of water. The best fact is that these tiny temperature gradients exist everywhere, even in some of the most remote places On earth h
#Researchers Develop Super-Hydrophobic Metal Surfaces Using Lasers Researchers have turned metal surfaces water repellent using femtosecond laser pulses.
This means that water will just bounce off their surface once it hits it. Chunlei Guo, a physicist at the Institute of Optics at the University of Rochester and the lead author of the study,
said, his is the first time that a multifunctional metal surface is created by lasers that is super-hydrophobic (water repelling),
the water actually gets bounced off. Then it lands on the surface again, gets bounced off again,
and ice and water in vertical resolution so it can aid boost these models. The U s. is encountering a rise in heavy rainfall events
In salt containing water, these have a natural tendency to form chains. A higher degree of attraction is exhibited on increasing the salt concentration.
an integrated system, in which sunlight can be used to split water into hydrogen and oxygen.
which is submerged in water to produce hydrogen. The technique involves genetically engineered bacteria in combination with a solar-powered catalyzer.
The catalyst, powered by sunlight, splits the water into hydrogen and oxygen. Following this, the bacterium Ralstonia eutropha combines hydrogen with carbon dioxide to form isopropanol p
they might even be able to pick up the movement of submarines below the water surface.
don look up in the air, look under the water. Yes, that right underwater aircraft carriers for drones. In yet another experiment, the U s. Naval Research Laboratory showed that it was possible to release a drone from a submerged submarine with the robotic drone shot out of a Tomahawk missile tube.
"This could revolutionise how we clean our water.""Preliminary research suggests they would be equally effective against pollution caused by antimicrobials in personal care products and antibiotic pharmaceuticals.
and can turn saline water palatable by removing its salty taste. MIT Mechanical engineering Phd student Natasha Wright worked for the project over three years to come up with the technology,
which initially focused on filtering biological contaminants from groundwater to make it potable. She joined MIT Mechanical engineering assistant professor Amos Winter's laboratory in 2012,
which uses electric potential to extract salt from the water. The ultraviolet light from the sun rays are used to kill biological contaminants in the water.
While similar desalination technologies have already been discovered, none of the available filters were able to remove the saltiness of the water post-treatment.
During her visits to rural India for the project, Wright found desalination devices were not much use to villagers.
though purified the water, could not eliminate its salty taste. Wright said:""The biggest surprise of the project so far has been this salt issue,
which will have a capacity to offer potable desalinated water for 5, 000 people. Wright and her research team have received a US Agency for International Development (USAID) grant for testing the system at full-scale for the first time in New mexico earlier in the year.
so spread out that it's more costly to pump in water from a municipal plant."
#California State Water Resources Control board adopts new emergency regulations LAGUNA NIGUEL, Calif. New emergency regulations adopted by California State Water Resources Control board (State Water Board) will go into effect June 1, according to a press release.
The regulations are designed to implement Gov. Jerry brown recent call for a 25 percent reduction of statewide water use,
stated the release. The State Water Board has assigned mandatory conservation goals to each urban area based on residential per capita water use to achieve this goal,
continued the release. Urban areas with the highest residential per capita water use are required to conserve more
with reduction goals ranging from eight to 36 percent, reported the release. his announcement solidifies the need to take conservation to the next level.
We are prepared to work with customers to ensure we deliver on the state-required 20 percent water-use reduction,
said Moulton Niguel Water District (MNWD) General manager Joone Lopez. t is now all of our responsibility to conserve as our efforts must collectively tie together to achieve the statewide 25 percent conservation mandate.
MNWD customers have achieved significant reductions in water use, resulting in the lowest annual water usage on record since 1991
