Hiding helium in helides in fusion reactors

Materials chosen for fusion reactors need to be able to withstand radiation damage and the effects of transmutation atoms such as helium. Previous work has suggested that nano-heterophases might offer greater radiation resistance and helium tolerance, but experimental evidence has been inconclusive. Researchers used the APS to probe further and settle the question.

The answer to low-temperature annealing is blowing in the electron wind

Seeking a different way to heal crystallographic defects, tested a low-temperature annealing technique utilizing electron wind force (EWF) to “push” defects out of materials. Evaluation showed that EWF is a viable, low-temperature way to reduce defects in degraded gallium nitride devices and partially recover electrical performance.

A Deeper Window into the Workings of Li-ion Battery Cathodes

A team of researchers has developed a new strategy for probing Li-ion battery workings at the microscopic level. Using the APS they were able to observe the dynamics of individual domains in the layered cathodes under charging and discharging.

Using fluid flow analysis to probe the microstructures of tooth enamel

Enamel, the hard outer coating of teeth, plays a critical role in protecting the underlying tooth structure from mechanical damage and decay. Researchers have employed a fluid mechanics method to characterize the microstructure of tooth enamel, paving the way for potential advancements in the development of ceramic materials.

Rejuvenating ether electrolytes for lithium-ion batteries

Using a specially designed electrolyte, a team of researchers has showed that it’s possible to achieve long-cycling graphite anode lithium-ion batteries with an ether-based solvent. Their findings could lead to batteries with high energy retention able to operate under extreme conditions.
