Research teams are trying different approaches within the nanotechnological field to improve water membrane technologies.

Nanotechnological innovations can improve water purification

One of these is to improve water purification by using nature’s own water-transporting channels, aquaporins. However, constructing suitable membranes for industrial processes is a challenge. Membranes for water purification are used in many applications and different types of membranes are being developed at the moment. No membrane can filter and purify water entirely, but improvements using novel kinds of membranes are made. In the European Commission-funded project MEMBAQ (Incorporation of Aquaporins in Membranes for Industrial Applications) researchers are taking advantage of a unique structure nature has already created, when they are developing a nanotechnological invention.

Planète Astronomie - Planète Astronomie : planètes et satellites du système solaire. Earth from Space. This true-color image shows North and South America as they would appear from space 35,000 km (22,000 miles) above the Earth.

Earth from Space

The image is a combination of data from two satellites. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA’s Terra satellite collected the land surface data over 16 days, while NOAA’s Geostationary Operational Environmental Satellite (GOES) produced a snapshot of the Earth’s clouds.

NASA spacecraft due for rendezvous with comet Tempel 1

On Valentine's Day, an aging Lothario that has been flitting from beauty to beauty through the solar system will make his final stop, taking pictures of a battered dowager to send to the folks back home before disappearing forever. The Stardust spacecraft, which has already taken images of asteroid Annefrank and captured interstellar dust from comet Wild 2, on Monday night will swing by comet Tempel 1. There, it will take new pictures of the devastation wrought on the comet by NASA's 2005 Deep Impact mission. NASA Science. European Space Agency. The European Space Agency (ESA) (French: Agence spatiale européenne - ASE) is an intergovernmental organisation dedicated to the exploration of space, with 20 member states.

European Space Agency

Established in 1975 and headquartered in Paris, France, ESA has a staff of more than 2,000 with an annual budget of about €4.28 billion / US$5.51 billion (2013).[1] ESA's space flight programme includes human spaceflight, mainly through the participation in the International Space Station programme, the launch and operations of unmanned exploration missions to other planets and the Moon, Earth observation, science, telecommunication as well as maintaining a major spaceport, the Guiana Space Centre at Kourou, French Guiana, and designing launch vehicles. The main European launch vehicle Ariane 5 is operated through Arianespace with ESA sharing in the costs of launching and further developing this launch vehicle.
