Catching a glimpse of the reactive intermediates in water in a trillionth of a second

DOE/US Department of Energy

The proton-transfer and ionization process in water leads to the formation of a hydroxyl-hydronium complex, a type of hydroxyl radical. The formation process causes ultrafast structural changes and the redistribution of energy among neighboring water molecules. Thanks to recent developments in liquid phase ultrafast electron diffraction techniques, scientists can capture these processes in real time.

Department of Energy announces $10 million for research on environmental systems science

DOE/US Department of Energy
Grant and Award Announcement

Today, the U.S. Department of Energy (DOE) announced $10 million in funding for 12 projects to universities, academic institutions, federal research labs, and nonprofits within the area of Environmental System Science (ESS) research. Grants will focus on studies intended to improve the understanding and representation of the impact of wildfires and floods on ecosystems and watersheds, as well the role of plant-mediated water redistribution and fungal networks in shaping ecosystem and watershed function.

Seeing double for better solar cells

DOE/US Department of Energy

Halide perovskite can make solar cells a thousand times thinner than today’s silicon solar cells. A new approach allows scientists to watch changes in the material’s structure and functional properties while the material solidifies into a thin film from solution. This gives new insight into how the material’s structure and functionality are related, aiding in future solar cell design.

Novel method examines the gas-liquid interface in new detail

DOE/US Department of Energy

Researchers have developed an apparatus to study reactions between gas molecules and highly volatile liquids at the gas-liquid interface with new levels of detail. The apparatus directs a molecular beam onto a flat liquid surface, and when the beam scatters, a detector collects data on the speed, direction, and mass of molecules in the scattered beam. The novel approach will help scientists understand combustion engines, air pollution, and other phenomena.

Haim Waisman: Then and Now / 2012 Early Career Award Winner

DOE/US Department of Energy

Haim Waisman develops computational models of the mechanics of materials. He focuses on fracture phenomena, such as ice breaking due to climate warming, infrastructure aging and deteriorating, energy extraction from rocks, and fractures in biomaterials such as bones.

Department of Energy announces $3.6 million for research traineeships to broaden and diversify nuclear physics

DOE/US Department of Energy
Grant and Award Announcement

Today, the U.S. Department of Energy (DOE) awarded more than $3.6 million with a focus on broadening and diversifying the nuclear and particle physics research communities through research traineeships for undergraduates from Historically Black Colleges and Universities (HBCUs) and other Minority Serving Institutions (MSIs). The goal of this program is to increase the recruitment and retention of students from groups under-represented in nuclear physics and to create new partnerships with HBCUs and MSIs. Only by accessing the broadest possible pool of potential physicists can the community produce the best possible science.

'Shining' light on the inner details and breakup of deuterons

DOE/US Department of Energy

Scientists have found a way to “see” inside deuterons, the simplest atomic nuclei, to better understand how particles called gluons are arranged within the deuteron. These collisions can also break the deuteron apart, giving insights into what holds the proton and neutron together. The research helps scientists understand how nuclei emerge from quarks and gluons, and how the masses of nuclei are dynamically generated by gluons.

Department of Energy announces $4.7 million for research and development partnership pilots

DOE/US Department of Energy
Grant and Award Announcement

Today, the U.S. Department of Energy (DOE) announced $4.7 million in funding for 35 new grants to colleges and universities that are under-represented in DOE’s foundational climate, Earth, and environmental science research investments. These grants will help provide technical assistance to build capacity and achieve the goal of broadening institutional participation in DOE’s science investments.

First atomic view of a quantum electronic device in operation

DOE/US Department of Energy

For the first time, researchers have used ultrafast electron diffraction to observe a quantum electronic device as it operates. Researchers observed atomic-level changes in the vanadium dioxide switch over millionths of a second, leading to the discovery of a short-lived intermediate state. The results may aid in the development of high-speed, high-efficiency quantum electronics and in the use of pulsed electric fields to create new engineered materials.
