Description:Literature Seminar Abstract\n\nIon insertion into a host materi
 al is the elementary process by which many energy storage based devices ar
 e built upon. For example\, rechargeable Li-ion batteries function via a p
 rocess of Li ions inserting into and extracting out of a host material in 
 the battery. This process results in the generation of electrons which can
  then go on to do work\, such as powering mobile phones\, laptop computers
 \, and Bluetooth headphones. Improving efficiency of these host materials 
 has been an ongoing investigation\, as investment into sustainable energy 
 is on the forefront of many funding projects. However\, fundamental unders
 tanding of the mechanism of ion insertion into a host material is arguably
  equally as important if optimal efficiency is to be attained. This paper 
 presents a method by which direct imaging of lithiation into a single nano
 wire of host material (WO3) occurs. The authors are able to identify and m
 easure a lithiation front as well as a phase change in real time of a sing
 le nanowire. Yet the same data presented in the paper can be analyzed furt
 her to gain more fundamental understanding of the system presented. Furthe
 r analysis includes opportunity to explore particle-particle interface and
  how this can effect diffusion of lithium through the wire of interest\, a
 s well as a discussion on identifying potential pseudocapacitive behavior 
 intrinsic to certain materials. 4:00 pm
