Machine learning model speeds up assessing catalysts for decarbonization technology from months to milliseconds
Scientists create computational model for identifying low-cost catalysts that convert biomass into fuels and useful chemicals with low carbon footprint
02-Mar-2023
Next time you drive past farms or prairies and ponds on a rural road, look around. They are a rich source of biomass. That includes corn, soybeans, sugar cane, switchgrass, algae and other plant matter. These carbon-rich materials can be converted to liquid fuels and chemicals with many possible ...
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 ...
On the road to better solid-state batteries
A Berkeley Lab-led team designs next-gen batteries at the atomic level
28-Feb-2023
A team from Lawrence Berkeley National Laboratory (Berkeley Lab) and Florida State University has designed a new blueprint for solid-state batteries that are less dependent on specific chemical elements, particularly critical metals that are challenging to source due to supply chain issues. Their ...
Next generation solar fuels: How a record-breaking copper catalyst converts CO₂ into liquid fuels
Researchers have made real-time movies of copper nanoparticles as they evolve to convert carbon dioxide and water into renewable fuels and chemicals
21-Feb-2023
Since the 1970s, scientists have known that copper has a special ability to transform carbon dioxide into valuable chemicals and fuels. But for many years, scientists have struggled to understand how this common metal works as an electrocatalyst, a mechanism that uses energy from electrons to ...
New compound that withstands extreme heat and electricity could lead to next-generation energy storage devices
Flexible polymers made with a new generation of the Nobel-winning “click chemistry” reaction find use in capacitors and other applications
17-Feb-2023
Society’s growing demand for high-voltage electrical technologies – including pulsed power systems, cars and electrified aircraft, and renewable energy applications – requires a new generation of capacitors that store and deliver large amounts of energy under intense thermal and electrical ...
Scientists unveil least costly carbon capture system to date
New system efficiently captures CO₂ and converts it into one of the world’s most widely used chemicals
27-Jan-2023
The need for technology that can capture, remove and repurpose carbon dioxide grows stronger with every CO2molecule that reaches Earth’s atmosphere. To meet that need, scientists at the Department of Energy’sPacific Northwest National Laboratoryhave cleared a new milestone in their efforts to ...
AI discovers new nanostructures
Researchers used artificial intelligence to rapidly discover new self-assembled nanostructures
18-Jan-2023
Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have successfully demonstrated that autonomous methods can discover new materials. Theartificial intelligence(AI)-driven technique led to the discovery of three new nanostructures, including a first-of-its-kind ...
A cool new method of refrigeration
Researchers hope that ionocaloric cooling could someday help replace refrigerants with high global warming potential and provide safe, efficient cooling and heating for homes
06-Jan-2023
Adding salt to a road before a winter storm changes when ice will form. Researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have applied this basic concept to develop a new method of heating and cooling. The technique, which they have named “ionocaloric ...
Spinoff opens new frontier for batteries
Blue Current achieves success with a breakthrough material: Top priority has been to develop a completely safe battery
03-Jan-2023
There is broad consensus that there is no silver bullet for climate change. Rather, many solutions will be required. What makes the challenge particularly daunting is the enormous reductions in greenhouse gas emissions needed in a short period of time. Some experts are concerned that there is not ...
Designing better battery electrolytes
Artificial intelligence and robot-assisted labs could help speed the search for better battery materials
21-Dec-2022
Looking at the future of battery materials. Designing a battery is a three-part process. You need a positive electrode, you need a negative electrode, and — importantly — you need an electrolyte that works with both electrodes. An electrolyte is the battery component that transfers ions — ...
