Scientists create computational model for identifying low-cost catalysts that convert biomass into fuels and useful chemicals with low carbon footprint
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 ...
Revolutionary breakthrough: The catalyst transforms motor oil, plastic and natural gas into sustainable materials
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 ...
A Berkeley Lab-led team designs next-gen batteries at the atomic level
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 ...
Researchers have made real-time movies of copper nanoparticles as they evolve to convert carbon dioxide and water into renewable fuels and chemicals
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 ...
Flexible polymers made with a new generation of the Nobel-winning “click chemistry” reaction find use in capacitors and other applications
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 ...
New system efficiently captures CO₂ and converts it into one of the world’s most widely used chemicals
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 ...
Researchers used artificial intelligence to rapidly discover new self-assembled nanostructures
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 ...
Researchers hope that ionocaloric cooling could someday help replace refrigerants with high global warming potential and provide safe, efficient cooling and heating for homes
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 ...
Blue Current achieves success with a breakthrough material: Top priority has been to develop a completely safe battery
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 ...
Artificial intelligence and robot-assisted labs could help speed the search for better battery materials
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 — ...
