Charged graphene foam acts as “uranium magnet” for water purification

Is there anything graphene can’t do? Researchers at MIT have found yet another use for the over-achieving wonder material, by making a reusable filter out of graphene oxide foam that acts like a magnet for uranium, effectively pulling the radioactive e… Continue reading Charged graphene foam acts as “uranium magnet” for water purification

MIT steam collector captures pure water for reuse in power plants

Nuclear and fossil fuel power plants consume huge amounts of water for cooling, which then goes to waste as water vapor. MIT engineers have now developed a system that can capture and recycle that lost water.Continue ReadingCategory: Environment, Scien… Continue reading MIT steam collector captures pure water for reuse in power plants

New solar still uses a rotating cylinder to produce more potable water

In many arid regions, people use devices known as solar stills to extract drinkable water from seawater or tainted water. A new type of solar still is claimed to be much more effective than others, by incorporating a rotating cylinder.Continue ReadingC… Continue reading New solar still uses a rotating cylinder to produce more potable water

Liquid water “lakes” on Mars may just be frozen clay, say new studies

A few years ago astronomers announced the incredible discovery of lakes of liquid water on Mars, buried beneath the ice cap at the south pole. But sadly, a trio of new papers refutes the claim, with new experiments suggesting that the “water” signal wa… Continue reading Liquid water “lakes” on Mars may just be frozen clay, say new studies

Metallic water created for the first time in golden experiment

Researchers have created metallic water for the first time. Through a very careful experimental setup, the team grew a thin layer of a gold-colored metallic water on the outside of a droplet of liquid metal.Continue ReadingCategory: ScienceTags: Water,… Continue reading Metallic water created for the first time in golden experiment

Study suggests smartphone screens could detect toxins in water

When we hear about smartphones being used to perform analytical tasks, there’s usually also a device that’s connected to the phone. According to a new study, however, a phone’s own touchscreen could soon be used to test drinking water and other liquids… Continue reading Study suggests smartphone screens could detect toxins in water

Mixed up membrane desalinates water with 99.99 percent efficiency

That ancient mariner was onto something when he said “water, water everywhere, nor any drop to drink” – the vast majority of water on Earth is undrinkable. Desalination could be a vital technology to meet the world’s drinking water needs, and now Korea… Continue reading Mixed up membrane desalinates water with 99.99 percent efficiency

Water study may wash out hopes for life on Venus

Hopes of finding life on Venus had already been dashed, but now a new study may have hammered the last nail into the coffin. New modeling of water activity on different solar system planets has found that Venus would be too dry for even the most extrem… Continue reading Water study may wash out hopes for life on Venus
