PET, the plastic used to make bottles, for example, is ubiquitous in our natural environment. In a joint study, scientists from Leipzig University and the Helmholtz Centre for Environmental Research (UFZ) investigated the negative effects that tiny plastic PET particles can have on the metabolism ...
New method simultaneously monitors clumps and the mixing intensity in a single step
Water is a vital resource, and clean water is a necessity. Texas A&M University researchers have developed a new technique to monitor one of the key processes of purifying water in real time. Raw water contains microscopic pathogens that are too small to remove during water and wastewater ...
Efficient disinfection of water with silver sulfide quantum dots in a peptide coat
Water contaminated with bacteria is a large threat to global health. A Chinese research team has described a simple new method of disinfection in the journal Angewandte Chemie. It is based on tiny biocompatible assemblies of atoms, known as quantum dots, made of silver sulfide with caps made of a ...
Sensor can identify the global content and form of arsenic-containing molecules at very low concentrations
It is a cruel paradox that on a planet with a surface mostly covered by water, hundreds of millions of people don’t have access to clean drinking water. As for the pollution of potable and natural water sources, one of the main culprits is arsenic, an abundant and toxic element in the earth’s ...
Breakthrough process was developed for drinking water treatment and toxic site remediation
An insidious category of carcinogenic pollutants known as “forever chemicals” may not be so permanent after all. University of California, Riverside, chemical engineering and environmental scientists recently published new methods to chemically break up these harmful substances found in drinking ...
KIT researchers and partners suspect that much more plastic is transported in flowing waters than previously assumed and are developing new modelling approaches
Whether in drinking water, food or even in the air: plastic is a global problem - and the full extent of this pollution may go beyond of what we know yet. Researchers at the Karlsruhe Institute of Technology (KIT), together with partners from the Netherlands and Australia, have reviewed ...
Olivier Gröninger is improving the drinking water supply for people in rural areas of South America with his Openversum project
'There are still two billion people in the world without access to clean drinking water,' says Olivier Gröninger, a postdoc in Professor Wendelin Stark’s group at ETH Zurich. These are the people whom the chemical engineer wants to help. Over the past five years, he has developed an inexpensive ...
Using common reagents in heated water, chemists can ‘behead’ and break down PFAS, leaving only harmless compounds
If you’re despairing at recent reports that Earth’s water sources have been thoroughly infested with hazardous human-made chemicals called PFAS that can last for thousands of years, making even rainwater unsafe to drink, there’s a spot of good news. Chemists at UCLA and Northwestern University ...
Funding from DOE’s National Alliance for Water Innovation supports UIC research
Engineers at the University of Illinois Chicago have been awarded just over $1 million from the U.S. Department of Energy’s National Alliance for Water Innovation to build a system that selectively removes and destroys poly- and perfluorinated substances, commonly called PFAS and referred to as ...
A fast, efficient, selective membrane for purifying saltwater
Water scarcity is a growing problem around the world. Desalination of seawater is an established method to produce drinkable water but comes with huge energy costs. For the first time, researchers use fluorine-based nanostructures to successfully filter salt from water. Compared to current ...
