By Jade Boyd – Boundary layers are ubiquitous in nature; they occur when raindrops fall on stone, water seeps through soil and the ocean meets the sea floor. Scientists and engineers have long been interested in accurately explaining how crystalline materials, including many minerals and stones, interact with and are dissolved by water. Calculations about the rate of these dissolution processes are critical in many fields of science and engineering.
At the boundary layer where quartz and water meet, multiple chemical reactions occur. Some of these happen simultaneously and others take place in succession.
The research could have wide-ranging impacts in diverse areas, including water quality and planning, environmental sustainability, corrosion resistance and cement construction. more> http://tinyurl.com/oj4wr2x

R&D – Instead of creating large amounts of power in one place—from large dams or even small turbines in water treatment plants—there’s value now in making tiny amounts of electricity anywhere there is a water source, from streams to water faucets.
Carnegie Mellon Univ.’s Diana Marculescu is leading a multidisciplinary team of industry and academic researchers to develop novel monitoring tools for placement and control of hydrokinetic generators throughout river systems nationwide. more> http://tinyurl.com/oc53cry

By David L. Chandler – Steam condensation is key to the worldwide production of electricity and clean water: It is part of the power cycle that drives 85% of all electricity-generating plants and about half of all desalination plants globally, according to the United Nations and International Energy Agency. So anything that improves the efficiency of this process could have enormous impact on global energy use.
It has been known for years that making steam-condenser surfaces hydrophobic could improve the efficiency of condensation by causing the water to quickly form droplets. But most hydrophobic materials have limited durability, especially in steamy industrial settings. The new approach to coating condenser surfaces should overcome that problem, the MIT researchers say. more> http://tinyurl.com/kltjnua

By David L. Chandler – Fog harvesting, as the technique is known, is not a new idea: Systems to make use of this airborne potable water already exist in at least 17 nations. But the new research shows that their efficiency in a mild fog condition can be improved by at least fivefold, making them far more feasible and practical than existing versions.
Fog-harvesting systems generally consist of a vertical mesh, sort of like an oversized tennis net. Key to efficient harvesting of the tiny airborne droplets of fog are three basic parameters, the researchers found: the size of the filaments in those nets, the size of the holes between those filaments and the coating applied to the filaments. more> http://tinyurl.com/kzupur2

Lab in a Can — Science Nation
NSF – Monitoring water quality is vital to make sure dangerous bacteria doesn’t creep into our drinking water or overcome sewage treatment plants. With support from NSF, engineers at the Monterey Bay Aquarium Research Institute have developed the Environment Sample Processor (ESP), a “DNA lab in a can.” The size of a trash can, it can be placed in the open ocean or at water treatment facilities to identify potentially harmful bacteria, algae, larvae and other microscopic organisms in the surrounding waters. It can monitor and send results back to the lab in real time to monitor water quality. Now, the engineers are modifying the ESP so it can go mobile, working from an autonomous underwater vehicle (AUV). more> http://tinyurl.com/n8u85uo

R&D – A research team from the National Physical Laboratory (NPL), the Univ. of Edinburgh and IBM’s TJ Watson Research Center reveals a major breakthrough in the modeling of water that could shed light on its mysterious properties.
Many models exist that can reproduce certain aspects of these properties but there is no ‘ultimate model’ that can reproduce them all.
The new approach could potentially be used for other substances and offers a new framework for simulation of materials at the atomic and molecular scale. more> http://tinyurl.com/l3tpds9

NASA – Data from a NASA planetary mission have provided scientists evidence of what appears to be a body of liquid water, equal in volume to the North American Great Lakes, beneath the icy surface of Jupiter’s moon, Europa.
NASA’s Galileo spacecraft, launched by the space shuttle Atlantis in 1989 to Jupiter, produced numerous discoveries and provided scientists decades of data to analyze. Galileo studied Jupiter, which is the most massive planet in the solar system, and some of its many moons.
One of the most significant discoveries was the inference of a global salt water ocean below the surface of Europa. This ocean is deep enough to cover the whole surface of Europa and contains more liquid water than all of Earth’s oceans combined. more> http://twurl.nl/fzsbny
