Recovery Of Degraded Lithium Ion Cathode Particles, James Kirtley
Recovery Of Degraded Lithium Ion Cathode Particles, James Kirtley
Undergraduate Research Conference at Missouri S&T
This project focuses on recovering the cathode materials of lithium ion batteries through atomic layer deposition (ALD) thin film coating. In industry, when a cathode material for a lithium ion battery are stored, it reacts with CO2 and moisture in the air creating Li2CO3 and LiOH on the particle surface. The harmful substances on the surfaces have a negative impact on battery performance and battery life. In this study, we found that when Li2Ni0.8Mn0.1Co0.1 (Ni-Rich NMC) is exposed to a high amount of moisture it degrades and the performance is reduced. For example, the discharge capacity of Degraded Ni-Rich NMC …
Effects Of Sleep Deprivation On Learning In Fruit Flies, Natalie Gardner
Effects Of Sleep Deprivation On Learning In Fruit Flies, Natalie Gardner
Undergraduate Research Conference at Missouri S&T
The fruit fly Drosophila Melanogaster is an optimal research specimen when observing the effects of sleep deprivation on spatial learning. A fly's sleep can be tracked using locomotion while it is undisturbed and while it undergoes sleep deprivation. To measure a fly's visuospatial awareness, a region at a comfortable 24 degrees Celsius, among the rest of the arena yielding an uncomfortable temperature ranging from 36-37 degrees Celsius, is fit with a specific visual cue that the fly is able to identify. This region, along with it's visual cue, is rotated around the arena every 3 minutes, and the amount of …
