What do smart water networks offer? The benefits of incorporating data analysis into a water network are better performance with the possibility of improved customer service,
and a uniquely detailed way to visualize the network's operations. On the technology side, smart water networks include the integration of supervisory control and data acquisition (SCADA),
meter data management solutions, advanced metering and automated meter reading and more. Those all enhance the ability to prevent the water loss prevalent in dumb systems through leak detection and control, pressure management, equipment repairs and asset management,
the company says. Schneider Electric describes four basic steps intended to occur over time. The following is a brief summary (learn more in the ferret article:

heat transfer in water condensation. In a steam-powered power plant, water is heated up to create steam that turns a turbine.
The turning of the turbine produces electricity. In this process, the steam is condensed back into water
and the whole process begins again. The MIT team looked at these condensers and found that by layering their surfaces with graphene they can improve the rate of heat transfer by a factor of four.
In some of these systems, the condensation takes the shape of a thin sheet of water coating the surface of the metal tubing;
in others, water droplets are formed. When a thin film is formed the heat transfer of the condensation is compromised.
The MIT researchers exploited the graphene coating hydrophobic qualities to ensure that the water formed into droplets.
After testing the material in an environment of pure water vapor at 100 degrees Celsius the researcher found that the graphene coating offered a fourfold improvement in heat transfer compared to bare metal.

The water is pretreated to remove oil and grease residue and solid particles. The company heats the saline water
and sprays it into a porous material with a large surface area, saturating air with water vapor. This water-saturated air is then pumped up through tiny holes in a series of shallow
water-filled trays. As bubbles pass through the water in the trays, the water vapor in the bubbles condenses
and joins the water it is passing through, creating more fresh water. This so-called ubble columnallows the company to condense water vapor without needing expensive metal heat exchangers.

#Bucktown Polymers water soluble Rinse Out 3d prinintg Resin (ROR) could replace lost wax casting Jun 1,

whereas the ROR is capable of being rinsed with water in a matter of minutes. Additionally, the material allows for higher pattern resolution, intricacy and better finishes than other similar materials.
Since the water rinse is ultimately replacing the burnout process, it is also eliminating the problem of unintended patterns that can be created from other materials due to polymer expansions or leftover ash and residue.

#DNA NANOSTRUCTURES Assembled in Waterless Solvent 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. he 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.
he added. inetic traps are among the bottlenecks for producing more complicated DNA NANOSTRUCTURES. lycholine 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
said Gállego. his solvent system preserves the DNA structures that have been developed to work in water. he solvent system could improve the combined use of metallic nanoparticles and DNA based materials.
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,

#Carbon nanotube-Based Water Desalination and Purification Technology Awarded Patent Mitra's new carbon nanotube immobilized membrane (CNIM) is an energy-efficient device designed to filter higher concentrations of salt than is currently feasible through reverse osmosis, one of the standard
It is used also to remove pollutants such as volatile organic compounds (VOCS)- chemicals routinely used in solvents-from water."
"Our hope is to expand the supply of water in places that really need it, while also reducing costs for industry."
Membrane distillation is a water desalination process in which heated salt water passes through a tubelike membrane,
called a hollow fiber, which allows only pure water vapor to permeate its walls. Potable water emerges from the net flux of water vapor
which moves from the warm to the cool side of the membrane where it condenses. Certain industries such as semiconductor manufacturing and pharmaceutical processing also require ultra-pure water for their operations.
Mitra, who has conducted research on carbon nanotubes for the past 15 years created a novel architecture for the membrane distillation process by immobilizing carbon nanotubes,
which are an atom thick and about 10,000 times smaller than a human hair in diameter, in the membrane pores.
"One of the key characteristics of carbon nanotubes is their capacity to both rapidly absorb water vapor as well as industrial contaminants,
In the case of fracking, the fresh water and chemicals that are pumped into the ground to release natural gas trapped beneath rocks absorb high concentrations of salt from the soil they pass through before returning as polluted water in need of treatment.
which relies on power-driven pump pressure to force water through a membrane, is used not commonly to treat this so-called produced water
because it typically contains very high concentrations of salt, requiring extremely high pressure. The electric power industry,
which uses a vast amount of water to cool its generators, is also eager to come up with more efficient processes to treat its wastewater,
"Our hope is to dramatically improve overall water and energy utilization, "Mitra said. Source: http://www. njit. ed d
