Could a magnetic sandwich make your electronic devices work more efficiently?

DOE/US Department of Energy

Researchers looking for materials that conduct electrons with near-zero resistance at normal operating temperature have found a promising candidate. The material, a layered "sandwich" of bismuth telluride and manganese bismuth telluride structure, exhibits the quantum anomalous Hall effect. In this effect, electrons with their spins all aligned in the same direction can travel along the edges of a material with almost no resistance.

Nuclear physics experiment helps identify conditions for a new astrophysical process

DOE/US Department of Energy

A new stellar process, the intermediate “i" process, has been proposed to explain new astronomical observations on nucleosynthesis. Scientists recently reported on the measurement of a nuclear reaction that affects the production of lanthanum in the i process. The measurement will help to improve scientific understanding of nucleosynthesis.

Department of Energy announces $6 million for research toward a more robust and reliable electric grid

DOE/US Department of Energy
Grant and Award Announcement

Two Department of Energy (DOE) offices have funded $6 million in research projects for an inaugural partnership to better prepare the nation for multiple disruptive power events and enable rapid response in a crisis for U.S. grid operators.

Simulating a critical point in quark gluon fluid

DOE/US Department of Energy

Scientists are conducting experiments in search of a critical point in the Quantum Chromodynamics phase diagram. The main signatures of this point involve changes in the number of particles produced in heavy ion collisions. Modeling these observables requires an extension of the standard fluid dynamic framework. Scientists have now developed an algorithm for performing simulations of a critical fluid and tested those simulations.

Drilling down to the details in cancer research

DOE/US Department of Energy

When an aggressive cancer launches an invasion on the human body, anything that can be done to slow down or better understand that fast-paced assault is going to be a bonus.

Tiny cavitation bubbles enhance energy conversion in fuel injectors’ jets

DOE/US Department of Energy

Scientists have a limited understanding of the effects of cavitation in microscopic devices. In this research, scientists took high-speed images of microscale cavitating fuel jets to understand the motion of liquid jets from high-pressure fuel injectors like those used in vehicle engines. Analysis of the results showed that cavitation enhances the energy conversion efficiency of the fuel injection.

DOE/US Department of Energy
Grant and Award Announcement

Funding of $5.65 million for 11 research projects in high energy density laboratory plasmas to better understand extreme environments was announced by the Department of Energy (DOE) today.

Smoother surfaces make for better particle accelerators

DOE/US Department of Energy

A new toolkit helps researchers build optimal superconducting radiofrequency (SRF) cavities that form the backbone of advanced particle accelerators. The cavities’ cleanliness, shape, and roughness of their inner surfaces contribute to their efficiency. In tests of the toolkit, scientists found that smoother cavities function more efficiently.

New mechanism explains rapid energy sharing across atomic semiconductor junctions

DOE/US Department of Energy

Understanding and controlling heat flow is critical for many applications, especially for electronics. As these devices become smaller, the interfaces between materials often become the bottleneck to removing heat. In this research, scientists uncovered a new mechanism for the transfer of energy across these interfaces that involves the coupling between electrons and atomic vibrations.

Lying in wait: MOF are traps for toxic gases

DOE/US Department of Energy

Metal organic frameworks (MOFs) show promise as a way to trap toxic molecules and mitigate their harmful effects. In this research, scientists studied how the structure of MOFs can be tuned to enhance and optimize trapping of nitrogen dioxide and sulfur dioxide.
