And this is just the tip of the iceberg for the case Necropsynth is making. Before, there may not have been any alternative in models and methods for dissection in anatomical studies.
Ozcan has created also a mobile device for detecting water contamination and a mobile microscope. t is quite important to have these kinds of mobile devices,
The researchers said they might likewise want to create materials that react to variables other than water, for example, high temperature and light.
They found that a medium with an embedded carbon nanoparticle results in a number of low energy electrons several times higher than that emitted by pure water.

Since oil is immiscible with water, a'string'was created of a number of blue, virtually identical, microdroplets.
#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,
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. he research on water-free solvents grew out of Georgia Tech research into the origins of life.

#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

#Vibrations of Water-Carrying Nanotubes for Improved Water filtration Systems Together, unsafe drinking water and the inadequate supply of water for hygiene purposes contribute to almost 90%of all deaths from diarrheal diseases
--and effective water sanitation interventions are still challenging scientists and engineers. A new study published in Nature Nanotechnology proposes a novel nanotechnology-based strategy to improve water filtration.
The research project involves the minute vibrations of carbon nanotubes called"phonons, "which greatly enhance the diffusion of water through sanitation filters.
The project was the joint effort of a Tsinghua University-Tel aviv University research team and was led by Prof.
"Through phonon oscillations--vibrations of water-carrying nanotubes--water transport can be enhanced, and sanitation and desalination improved.
however, we witnessed three times the efficiency of water transport, and, of course, a great deal of energy saved."
such vibrations produce a 300%improvement in the rate of water diffusion by using computers to simulate the flow of water molecules flowing through nanotubes.

#Coral-Like Nanoplates Help Remove Toxic Heavy metals from Water A new material that mimics coral could help remove toxic heavy metals like mercury from the ocean,
Toxic heavy metal ions like mercury, lead and arsenic are released into the water through human activity, including manufacturing and industrial processes.
One major source of toxic metal contamination is the ocean. When mercury pollutes the water
plants and animals absorb it. The mercury builds up in the food chain, ultimately resulting in toxic fish.

#Saturas Successfully Conducts Field trials of Embedded Stem Water Sensor The field tests were conducted on peach and citrus trees at the Hula Valley Orchards Experimental Farm.
The results were consistent with the stem water potential measurement using manual measurement tools and successfully demonstrated continuous measurement of the water status in the tree.
Based on the research of Dr. Moshe Meron Saturas has developed a miniature stem water potential (SWP) sensor that is embedded in the trunks of trees vines and plants.
SWP is recognized a scientifically highly accurate parameter for determining water status in crops but today SWP can only be measured in a labor-intensive procedure.
The Saturas sensor provides accurate information for optimized irrigation to reduce water consumption with no stress to the plants and increases fruit production and quality.
The Saturas sensing system tailors irrigation to the crop's real-time water needs resulting in more efficient water use

water-based liquids slip to a new location in the tube, get stuck, then slip again
the water propagates at a nearly constant speed into the hydrogel-coated capillary. This was very different from
When the opening of a thin glass tube is exposed to a droplet of water, the liquid begins to flow into the tube, pulled by a combination of surface tension in the liquid and adhesion between the liquid and the walls of the tube.
Leading the way is a meniscus, a curved surface of the water at the leading edge of the water column.
Water entering a tube coated on the inside with a dry hydrogel film must first wet the film
but with discrete steps in which the water meniscus first sticks and its motion remains arrested
This tick-slipprocess forces the water to move into the tube in a step-by-step motion. The flow rate measured by the researchers in the coated tube is three orders of magnitude less than the flow rate in an uncoated tube.
said Fedorov. hough there is some swelling of the hydrogel upon contact with water, the change in the tube diameter is negligible due to the small thickness of the hydrogel layer.
Water absorption by the hydrogels occurs only when the materials remain below a specific transition temperature.
the materials no longer absorb water, eliminating the tick-slipphenomenon in the microtubes and allowing them to behave like ordinary tubes.
This ability to turn the stick-slip behavior on and off with temperature could provide a new way to control the flow of water-based liquid in microfluidic devices,
