A hydrogel has appeared that quickly extracts fresh water from the air

Researchers have figured out how to quickly extract large amounts of fresh water from the air using a hydrogel containing hygroscopic salt. Materials scientist Guihua Yu and his team at the University of Texas at Austin, USA, have developed a salt-compatible hydrogel that can absorb and retain water when combined with hygroscopic salt. Hydrogels can...

Developed a fast and effective way to remove the “eternal chemicals” from drinking water

The technology effectively removes and destroys synthetic organofluorine chemicals (PFAS). Researchers from the Faculty of Civil and Environmental Engineering at the Technion Israel Institute of Technology have developed an innovative technology to remove hazardous contaminants from drinking water. The study was led by Drs Adi Radian and Samapti Kundu. PFAS are a family of problematic...

Chemists turn used medical masks and sheets into a material to purify water from oil

An interesting way of using polymer medical waste: from masks to used sheets, was found by chemists from Tomsk Polytechnic University. Scientists have come up with a material capable of absorbing oils with high efficiency. The results of this study have already been published in the peer-reviewed journal Journal of Environmental Chemical Engineering. The material...

Switzerland has developed an edible alternative to plastic packaging

Scientists from the Swiss research organization Empa have partnered with retailer Lidl Switzerland to develop a protective cellulosic coating for fruits and vegetables. It is made from pomace, a substance that can be extracted from the skin of fruits and vegetables. The coating can be applied to fruits and vegetables to extend their shelf life....

Biodegradable corn based film helps food last longer

Scientists have developed an antibacterial and biodegradable corn based film. It is environmentally friendly and helps products to last longer. Despite the fact that many people are starving, most of the food is thrown away. It deteriorates too quickly. The new packaging material made from natural materials extends the shelf life of products and also...
