New approach to radioisotope power sources for improved efficiency and long life

DOE/US Department of Energy

Beta-voltaic radioisotope power sources last for years under harsh conditions without maintenance, making them ideal for applications such as spacecraft. These devices directly convert beta particles from a radioisotope into electrical energy. Researchers recently explored a new approach for making beta-voltaic RPSs more efficient at converting heat into electricity, making these RPSs even better for providing long-term, compact power in remote and extreme environments, especially in small devices.

DOE/US Department of Energy
Grant and Award Announcement

The U.S. Department of Energy (DOE) announced $9.25 million for research in the behavior and properties of structural materials under molten salt reactor conditions, via collaborations that enable effective use of DOE’s high performance computers.

Connected moments and quantum computing improve “many body” chemical simulations

DOE/US Department of Energy

Advancing quantum computing requires models that can solve challenging many-body problems quickly and accurately. This research proposes a new algorithm for performing quantum calculations on chemical systems using a mathematical tool called “connected moments.” This reduces the number of qubits needed to reach target levels of accuracy and could lead to advances in chemistry and applications in catalysis, biochemistry, and materials.

The U.S. Department of Energy (DOE) announced a plan to provide up to $110 million for basic research and technology development to design and engineer plants and microbes for the production of advanced biofuels, bioproducts, and biomaterials.

Unlocking the mysteries of globular clusters of stars

DOE/US Department of Energy

Globular clusters are collections of hundreds of thousands of stars that scientists believe evolved completely isolated from the rest of the universe. As such, they are perfect “stellar laboratories.” This research turned to the nuclear physics of an important type of reaction involving the sodium in these stars to help unlock what happened in the interiors of these stars to create the universe as we know it today.

Transforming material topology with a drop of liquid

DOE/US Department of Energy

Researchers inspired by natural cells are developing their own materials made of interconnected microscopic shapes. But synthetic materials can’t be reshaped as many ways as biological materials without breaking apart and being rebuilt from scratch. This study introduces a new way to manipulate a material’s arrangement of cells at the microscale using a simple liquid, opening new possibilities for innovative materials.
