  • Calculating ‘old’ and ‘new’ water runoff

    Just ahead of a rainstorm, Cody Ross might run out to an agricultural research site as part of his graduate work. He’ll need to get some dye into an injection well. The point? To evaluate the path that water follows from the field during and after the rainstorm. Ross, a member of the Watershed Systems Research Program at the University of Manitoba, is measuring water flow in a part of ...

  • Low energy water purification enabled by nanomaterial-coated sponges

    A low cost, low energy method to disinfect water using electricity has been developed by researchers by combining carbon nanotubes (CNTs) and silver nano-wires with existing materials. The technology has the potential to be used in portable disinfection devices in developing countries. Globally, an estimated 1.3 million children under five die every year from diarrhoeal diseases. Many of these ...

  • Ozone, nitrogen change the way rising carbon dioxide affects earth`s water

    Through a recent modeling experiment, a team of NASA-funded researchers have found that future concentrations of carbon dioxide and ozone in the atmosphere and of nitrogen in the soil are likely to have an important but overlooked effect on the cycling of water from sky to land to waterways. The researchers concluded that models of climate change may be underestimating how much water is likely to ...

  • Electrified nanostructure high-speed filter

    Stanford researchers have developed a water-purifying filter that makes the process more than 80,000 times faster than existing filters. The key is coating the filter fabric (ordinary cotton) with nanotubes and silver nanowires and then electrifying it. The filter uses very little power, has no moving parts and could be used throughout the developing world. By dipping plain cotton cloth in a ...

  • Using bacteria to self-heal cracks in concrete

    Some types of bacteria show the potential to act as self-healing agents in concrete, according to a recent study. This could make the construction material more durable and therefore more sustainable. Typically, concrete consists of 300kg of cement, 180 litres of water and 1890kg of aggregates per m3. Cement production has an impact on the environment as it is very energy intensive, accounting ...

  • Thirsty Australia Advances Desalination Technology

    Melbourne, Australia - The delivery of energy efficient water desalination to drought-stricken Australia received a boost today with the establishment of a new collaboration between the government research agency CSIRO and nine Australian universities. The research aims to advance water desalination as an alternative water supply option for Australia by increasing efficiency, and reducing the ...

  • ORNL-led team demonstrates desalination with nanoporous graphene membrane

    Less than 1 percent of Earth’s water is drinkable. Removing salt and other minerals from our biggest available source of water—seawater—may help satisfy a growing global population thirsty for fresh water for drinking, farming, transportation, heating, cooling and industry. But desalination is an energy-intensive process, which concerns those wanting to expand its application. ...
