A newly developed catalyst makes single-use plastics easier to upcycle, recycle, and biodegrade
Revolutionary breakthrough: The catalyst transforms motor oil, plastic and natural gas into sustainable materials
28-Feb-2023
Researchers created a new catalyst that transforms hydrocarbons into chemicals and materials that are higher value, easier to recycle, and biodegrade in the environment. This catalyst transforms materials such as motor oil, plastics in single-use grocery bags, water or milk bottles, and their ...
New discoveries made about a promising solar cell material, thanks to new microscope
23-Nov-2022
A team of scientists from the Department of Energy’s Ames National Laboratory developed a new characterization tool that allowed them to gain unique insight into a possible alternative material for solar cells. Under the leadership of Jigang Wang, senior scientist from Ames Lab, the team ...
Scientists use copper nanowires to combat the spread of diseases
02-Aug-2022
An ancient metal used for its microbial properties is the basis for a materials-based solution to disinfection. A team of scientists from Ames National Laboratory, Iowa State University, and University at Buffalo developed an antimicrobial spray that deposits a layer of copper nanowires onto ...
A unique catalyst paves the way for plastic upcycling
31-May-2022
A recently developed catalyst for breaking down plastics continues to advance plastic upcycling processes. In 2020, a team of researchers led by Ames Laboratory scientists developed the first processive inorganic catalyst to deconstruct polyolefin plastics into molecules that can be used to ...
A “fairly simple” breakthrough makes accessing stored hydrogen more efficient
New catalyst extracts hydrogen from hydrogen storage materials easily and efficiently
15-Feb-2022
A new catalyst from the U.S. Department of Energy’s Ames Laboratory and collaborators extracts hydrogen from hydrogen storage materials easily and efficiently. The process occurs at mild temperatures and under normal atmospheric conditions, without using metals or additives. The breakthrough ...
Plastics could see a second life as biodegradable surfactants
A new chemical process provides biodegradable chemicals
30-Apr-2021
Scientists at the Institute for Cooperative Upcycling of Plastics (iCOUP), an Energy Frontier Research Center led by Ames Laboratory, have discovered a chemical process that provides biodegradable, valuable chemicals, which are used as surfactants and detergents in a range of applications, from ...
Borrowing from birds, experts reduce search times for novel high-entropy alloys to seconds
Hybrid CS algorithm borrows from behavior of cuckoo birds
18-Jan-2021
Computational materials science experts at the U.S. Department of Energy's Ames Laboratory enhanced an algorithm that borrows its approach from the nesting habits of cuckoo birds, reducing the search time for new high-tech alloys from weeks to mere seconds. The scientists are investigating a type ...
A first-of-its-kind catalyst mimics natural processes to break down plastics
The new catalyst is able to process polymers widely used in things like plastic grocery bags, milk jugs, shampoo bottles, toys, and food containers
22-Oct-2020
While plastics recycling is not new science, current processes don't make it economically worthwhile-- waste plastics get "down-cycled" into lower grade, less useful material. It's a challenge that continues to be an obstacle in tackling a growing global pollution crisis in single use plastics. A ...
New Nitrogen Assembly Carbon catalyst has potential to transform chemical manufacturing
More sophisticated and challenging chemical transformations without the need for transition metals
28-Aug-2020
Scientists at the U.S. Department of Energy's Ames Laboratory have discovered a metal-free carbon-based catalyst that has the potential to be much less expensive and more efficient for many industrial concerns, including manufacturing of bio- and fossil fuels, electrocatalysis, and fuel cells. At ...
New discovery settles long-standing debate about photovoltaic materials
21-Apr-2020
Scientists have theorized that organometallic halide perovskites - a class of light harvesting "wonder" materials for applications in solar cells and quantum electronics - are so promising due to an unseen yet highly controversial mechanism called the Rashba effect. Scientists at the U.S. ...
