Novel Way to Boost the Performance of Solid-State Batteries
Written by AZoMMay 21 2021
Although solid-state batteries can pack plenty of energy into a compact space, their electrodes are not that good at making a contact with their electrolytes.

Liquid electrolytes spark energy by reaching all nooks and corners of an electrode, but liquids also tend to take up a lot of space without preserving energy and also fail in due time.
Now, scientists have identified a new way to allow solid electrolytes to make contact with electrodes that are composed of strategically arranged materials at the atomic level and the outcomes are supporting the drive toward more improved solid-state battery technologies.
Living Memory Home offers virtual and personal memorial space for mourners
When a loved one dies, memories of that person become particularly valuable in connecting the mourners with the deceased. A new Weill Cornell Medicine online application, called Living Memory Home, offers a virtual and personal memorial space that allows mourners to deposit their memories and feelings about their loss and honor their loved one.
Living Memory Home users are able to create a memorial space that they can personalize with photos and messages. They can customize a virtual cabin and choose an appropriate view. The curated set of questions prompt users to write memories and feelings about their loved one.

Nicole Xu, Ph.D., a U.S. Naval Research Laboratory (NRL) Postdoctoral Research Associate from the Laboratories for Computational Physics & Fluid Dynamics designs faster and more energy efficient underwater vehicles using bioinspired shark skin-like surfaces.
“Shark skin comprises arrays of teeth-like denticle structures, which contribute to fast and stealthy swimming by turbulent drag reduction,” Xu said. She began her NRL postdoctoral associateship in January 2021.
“Xu has demonstrated extraordinary motivation and initiative, as well as technical expertise in the area of unpiloted systems research,” said Jason Geder, an NRL aerospace engineer who is Xu’s mentor.
Xu’s goal is to test these bioinspired surfaces on hydrofoils in flow channels before implementing the skins onto unpiloted underwater vehicles (UUV), such as the NRL-developed WANDA UUV and other traditional underwater vehicles.
