Compared to X-ray imaging, neutron fluxes are much lower, thus speed and spatial resolution cannot compete with X-ray imaging. However, neutron-matter interactions, especially with crystalline materials, offer unique contrast mechanisms. We have shown that neutron imaging is sensitive to the lithium-graphite structures of charged lithium-ion polymer batteries, even when imaging an intact, commercial battery. Processing raw neutron images into clean 3D volumes is challenging. First, the "sit still" requirement is violated when imaging a dynamic system; this problem is partially alleviated with a Greek golden ratio based angle order. Second, the inverse Radon transform requires [0,1] neutron-matter interactions, a poor assumption for thicker samples. Third, the large data volumes are challenging to reduce to a single scalar description of the complex sample. Butler is a co-PI on an instrument development team seeking a $20M neutron imaging beamline at the ORNL Spallation Neutron Source, thus solutions to these problems are welcomed</span><b><span style="font-size: 11pt; font-family: Calibri, sans-serif; "><o:p></o:p></span></b></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; text-align: justify; "><span style="color: rgb(31, 73, 125); "><o:p> </o:p></span></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 10.5pt; font-family: Consolas; "><span style="font-size: 11pt; font-family: Calibri, sans-serif; ">The access grid locations are as follow:<o:p></o:p></span></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 10.5pt; font-family: Consolas; "><span style="font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></span></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; line-height: 17px; "><u>Tulane:</u><span class="Apple-converted-space"> </span>AG room: 403 Stanley Thomas Hall<o:p></o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; line-height: 17px; "><u>University of Louisiana at Lafayette</u>: AG room: Abdalla Hall<o:p></o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; line-height: 17px; "><u>Southern University:</u> AG room: 218 Moore Hall<o:p></o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; line-height: 17px; "><u>UNO:</u><span class="Apple-converted-space"> </span>AG room: <span class="Apple-converted-space"> </span><span style="color: black; ">SC 2002</span><o:p></o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; line-height: 17px; "><u>LSU:</u><span class="Apple-converted-space"> </span>AG room: Johnston 338<o:p></o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; line-height: 17px; "><u>LATECH:</u><span class="Apple-converted-space"> </span>AG room: 234 Netken Hall<o:p></o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 10.5pt; font-family: Consolas; text-align: justify; "><span style="font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></span></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 10.5pt; font-family: Consolas; text-align: justify; "><span style="font-size: 11pt; font-family: Calibri, sans-serif; ">Please, distribute this email to your students and colleagues.<o:p></o:p></span></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; ">Kind Regards,<o:p></o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; ">Dentcho<o:p></o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; ">----<o:p></o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; ">Dentcho A.
