X-ray tomography helps reveal how solid state batteries charge, discharge

Science
Jan. 28 (UPI) -- With the help of X-ray tomography, scientists have for the first time observed the evolution of materials inside solid state batteries during the charging and discharging processes. The breakthrough observations -- detailed Thursday in the journal Nature Materials -- could help researchers develop more efficient solid state battery materials. Advertisement For their study, researchers used a complicated imaging technology called operando synchrotron X-ray computed microtomography to observe changes in a battery's electrode material at the interface between lithium and solid-state electrolytes. The unprecedented images showed the charge-discharge process causes voids to form at the interface, causing loss of contact between the lithium and solid-state electrolytes and trig...

‘Invisible’ words reveal common structure among famous stories

‘Invisible’ words reveal common structure among famous stories

Science
Aug. 7 (UPI) -- Storytelling requires a narrative arc, but the trajectory of a dramatic arc isn't always obvious. By tracing the abundance of "invisible" words -- pronouns, articles and other short words -- researchers were able to identify patterns shared by a diversity of stories, from Shakespeare to Spielberg, according to a study published Friday in Science Advances. Advertisement "Over the years, these 'invisible' words have been found to be related to a whole mess of psychological processes -- how people use small words like articles and pronouns tell us about a person's mental health, thinking style, their social status, and even how well they get along with other people," study lead author Ryan Boyd told UPI. "In many ways, it was a natural progression to look at what these words ...
