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. 

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.

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.

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.

Splitting water using renewable electricity to produce green hydrogen is seen by many as essential for achieving net-zero carbon emissions. A group of scientists has recently demonstrated a new type of low-cost catalyst that could slash the cost and boost the efficiency of green hydrogen production through water splitting.
