Scientists see evidence of first-order phase change in nuclear matter

DOE/US Department of Energy

New evidence suggests protons and neutrons go through a “first-order” phase transition to reach their melted state, a soup of quarks and gluons. This is a kind of stop-and-go change in temperature is similar to how ice melts: energy first increases the temperature. The temperature then stays steady while the energy transforms a solid to a liquid. Only when all the molecules are liquid can the temperature increase again.

Setting a scientific foundation for critical materials

DOE/US Department of Energy

Critical materials are essential for many key technologies, including batteries and wind turbines. The Department of Energy is working to reduce the need for them, recycle them, and expand domestic sources of them.

Department of Energy announces $25 million investment in polymer upcycling research to reduce plastics waste

DOE/US Department of Energy
Grant and Award Announcement

The U.S. Department of Energy (DOE) announced $25 million in funding for 10 research projects to build the scientific foundations for new technology solutions that reuse discarded plastics to make valuable products and reduce plastics waste.

The magic is gone for neutron number 32

DOE/US Department of Energy

Protons and neutrons orbit atomic nuclei in shells with caps on how many protons or neutrons they can hold. Full shells mean stable, compact nuclei. Physicists call the number of protons or neutrons in a “magic” numbered full shell. New research shows that a previously reported “magicity” for number 32 does not appear in neutron-rich potassium isotopes.

DOE invests $13.7 million for research in data reduction for science

DOE/US Department of Energy
Grant and Award Announcement

The U.S. Department of Energy (DOE) announced $13.7 million in funding for nine research projects that will advance the state of the art in computer science and applied mathematics.

DOE awards $30M to secure domestic supply chain of critical materials

DOE/US Department of Energy
Grant and Award Announcement

The U.S. Department of Energy (DOE) announced $30 million in funding for 13 national lab and university-led research projects to develop new technologies that will help secure the supply of critical materials that build clean energy technologies.

Negative triangularity—a positive for tokamak fusion reactors

DOE/US Department of Energy

In a conventional tokamak, the cross-section of the plasma is shaped like the letter D. Facing the straight part of the D on the inside side of the donut-shaped tokamak is called positive triangularity. New research suggests that reversing the plasma—negative triangularity--reduces how much the plasma interacts with the surfaces of the tokamak for reduced wear.

DOE announces $26 million to advance chemical and materials sciences with data science

DOE/US Department of Energy
Grant and Award Announcement

The U.S. Department of Energy (DOE) announced $26 million in funding to harness cutting-edge research tools for new scientific discoveries fundamental to clean energy solutions.

Computers help scientists understand the particles that make up atoms

DOE/US Department of Energy

To reduce the need for computer power, researchers typically simulate how quarks combine to make up larger particles by simulating quarks heavier than quarks found in nature. Now, using the Summit supercomputer, a team simulated much lighter quarks than possible in the past. This produced more realistic results that will help scientists investigate the Higgs boson.

Department of Energy announces $17.5 million for particle accelerators for science & society and workforce training

DOE/US Department of Energy
Grant and Award Announcement

The U.S. Department of Energy (DOE) announced $17.5 million in funding for advanced research projects in particle accelerator science and technology as well as university-based traineeships that will build a diverse, skilled pipeline of American scientists and engineers in the fields of high energy physics accelerators and instrumentation.
