A new generation of high surface-area porous materials for removing atrazine from water supplies has been developed by researchers at the University of Illinois at Urbana-Champaign. The low-cost and wear-resistant fibers also can remove the hazardous contaminants chloroform and trichloroethylene, both byproducts of the commonly used chlorine disinfection process.
"We’ve shown that we can remove all these impurities to well below the maximum contaminant levels established by the Environmental Protection Agency," said James Economy, a professor of materials science and engineering at Illinois. "Having increased pore size and higher surface area, these fibers work much better than commercially available granulated activated carbon."
Atrazine is one of the most widely used herbicides in the United States. More than 75 million pounds of atrazine are applied annually. Spread on farm fields and residential lawns to control weeds, atrazine can work its way into local waterways and municipal drinking supplies. Millions of Americans unknowingly ingest atrazine with their tap water.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
