#Lasers create surface so hydrophobic that water bounces off like a ball In the study of hydrophobic surfaces,
Now, researchers at the University of Rochester have used lasers to create a surface so hydrophobic that a single droplet of water can bounce up and down on it multiple times like a ball.
and greatly increase visibility while driving through a storm as water smoothly slides off the glass.
the surface etched pattern is so hydrophobic that water literally bounces off, falls back down to the surface,
Water rolls off the laser-etched surfaced when it titled less than five degrees, whereas a common Teflon pan has to be turned a steep 70 degrees.

This type of surface could help keep latrines clean in areas of the world where water is scarce.
By confining water to the nanoscale in specially designed hydroscopic materials, it possible to convert energy from evaporation to mechanical work.

#Indian-origin scientist Manu Prakash develops computer that operates on water droplets A computer that operates using the unique physics of moving water droplets has been developed by an Indian-origin scientist and his team.
Then they carefully injected into the mix individual water droplets that had been infused with tiny magnetic nanoparticles.

#How lasers make metal super water repellent Scientists have used lasers to turn metals into extremely water repellent materials without the need for temporary coatings.
Water repellent, or super-hydrophobic, materials are desirable for a number of applications, such as rust-prevention, anti-icing,
And it is these patterns that make the metals repel water. he material is so strongly water-repellent,
the water actually gets bounced off. Then it lands on the surface again gets bounced off again,
you need to tilt the surface to nearly a 70-degree angle before the water begins to slide off.
As the water bounces off the super-hydrophobic surfaces it also collects dust particles and takes them along for the ride.
Roughly half of the dust particles were removed with just three drops of water. It took only a dozen drops to leave the surface spotless.
collecting rain water is vital and using super-hydrophobic materials could increase the efficiency without the need to use large funnels with high-pitched angles to prevent water from sticking to the surface,
says Guo. second application could be creating latrines that are cleaner and healthier to use.
Latrines are a challenge to keep clean in places with little water. By incorporating super-hydrophobic materials,
a latrine could remain clean without the need for water flushing. But challenges still remain to be addressed before these applications can become a reality, Guo states.
The combination of light-absorbing properties with making metals water repellent could lead to more efficient solar absorbersolar absorbers that don rust
meaning they attract water. In fact, the materials were so hydrophilic that putting them in contact with a drop of water made water run phill.
Guo team is now planning on focusing on increasing the speed of patterning the surfaces with the laser,
as well as studying how to expand this technique to other materials such as semiconductors or dielectrics, opening up the possibility of water repellent electronics.

The semiconductor device converts the temperature gradient (the heat of the candle against the coolness of the water) into electricity.
The inventors recommend changing the water every 30 minutes to keep the temperature gradient in place, but this can be shortened to every 10 minutes to create a greater average power output.

#Who needs water to assemble DNA? Non-aqueous solvent supports DNA NANOTECHNOLOGY Abstract: Scientists around the world are using the programmability of DNA to assemble complex nanometer scale structures.
Until now, however, production of these artificial structures has been limited to water-based environments, because DNA naturally functions inside the watery environment of living cells.
Researchers at the Georgia Institute of technology have shown now that they can assemble DNA NANOSTRUCTURES in a solvent containing no water.
They also discovered that adding a small amount of water to their solvent increases the assembly rate
we have shown that DNA NANOSTRUCTURES can be assembled in a water-free solvent, and that we can mix water with the same solvent to speed up the assembly.
We can also take the structures that were assembled in this solvent mixed with water emove the water by applying vacuum
and have the DNA structures remain intact in the water-free solvent. The assembly rate of DNA NANOSTRUCTURES can be very slow,
and depends strongly on temperature. Raising the temperature increases this rate, but temperatures that are too high can cause the DNA structures to fall apart.
and adding water can adjust the solvent viscosity, which allows for faster assembly compared to the water-free version of the solvent. his solvent changes the rules,
said Isaac Gállego, a postdoctoral researcher in Hud lab and the paper first author. e now have a tool that controls DNA assembly kinetics and thermodynamics all in one solvent.
Glycholine is miscible in water so it can be mixed in any ratio with water to control the kinetics of the assembly process.
For instance, one structure that assembles in six days in pure solvent will assemble in three hours in a glycholine solution containing 10 percent water.
A key feature of the new solvent system is that it does not require changes to existing DNA NANOTECHNOLOGY designs that were developed for water. ou can go back
and forth between hydrated and non-hydrated states, said Gállego. his solvent system preserves the DNA structures that have been developed to work in water.
The solvent system could improve the combined use of metallic nanoparticles and DNA based materials. In the typical aqueous solvents where DNA NANOTECHNOLOGY is performed
The solvent low volatility could also allow storage of assembled DNA structures without the concern that a water-based medium would dry out.
In future work, they hope to use the control provided by water-free solvents to obtain dynamic DNA structural rearrangements that are not possible in water,
both at Georgia Tech. hat was surprising was finding a solvent that allows the assembly of structures more easily than in water.
because DNA NANOTECHNOLOGY was developed in water. The research on water-free solvents grew out of Georgia Tech research into the origins of life.
Hud and colleagues had wondered if the molecules necessary for life, such as the ancestor of DNA, could have developed in a water-free solution.
In some cases he noted, the chemistry necessary to make the molecules of life would be much easier without water being present. his work was inspired by research into the origins of life with the basic question of
whether complex DNA structures could exist in non-aqueous solvents, and we showed that they can,
