Scientists of Tomsk Polytechnic University jointly with the University of Lille (France) have developed a new material capable of purifying water effectively from oil products. It is based on an ordinary household polyurethane sponge. The research team made it superhydrophobic - it repels water, ...
The power of attraction
Glyphosate is not only one of the most widely-used herbicides in the world, but also one of the most controversial chemical compounds, as it is suspected of being carcinogenic. In a study published in the journal Nature Sustainability, a team of researchers from FAU have demonstrated how ...
Providing Safe, Clean Water
In many parts of the world, access to clean drinking water is far from certain. Filtration of large volumes of water, however, is slow and impractical. In the journal Angewandte Chemie, scientists have introduced a new water purification method based on magnetic nanoparticles coated with a ...
Mussels are notorious maritime stowaways known for damaging the hulls of boats, but these same adhesive properties have widespread engineering applications, scientists in China and the United states write in review published in the journal Matter. They suggest that the chemistry of mussel threads ...
Another potential -- and renewable -- tool to fight harmful algal blooms
Scientists at The University of Toledo have discovered that rice husks can effectively remove microcystin from water, a finding that could have far-reaching implications for communities along the Great Lakes and across the developing world. An abundant and inexpensive agricultural byproduct, rice ...
Scientists from the National University of Science and Technology "MISIS" together with their colleagues from Derzhavin Tambov State University and Saratov Chernyshevsky State University have figured out that graphene is capable of purifying water, making it drinkable, without further ...
Researchers at the National Institute of Standards and Technology (NIST) have conducted simulations suggesting that graphene, in addition to its many other useful features, can be modified with special pores to act as a tunable filter or strainer for ions (charged atoms) in a liquid. The concept, ...
A new type of photocatalysts -- nanostructures from titanium dioxide
A RUDN chemist developed a new type of photocatalysts - nanostructures from titanium dioxide. Hollow nanocubes with ultra-thin walls act like nanoreactors and provide for 28 fold more effective organic reactions at room temperature under the influence of visible light. Traditional methods of ...
Australian researchers have designed a rapid nano-filter that can clean dirty water over 100 times faster than current technology. Simple to make and simple to scale up, the technology harnesses naturally occurring nano-structures that grow on liquid metals. The RMIT University and University of ...
Nanoscale solution to ‘produced water’ problem
Oil and water tend to separate, but they mix well enough to form stable oil-in-water emulsions in produced water from oil reservoirs to become a problem. Rice University scientists have developed a nanoparticle-based solution that reliably removes more than 99 percent of the emulsified oil that ...
