In many commercial cells, long tabs at both cell sides, leading to uniform potentials along the spiral direction of wound jelly rolls, are rarely seen because of their high manufacturing cost. More often, several metal strips are welded at discrete locations along both current collector foils. With this design, the difference of electrical potentials is easily built up along current collectors in the spiral direction. Hence, the design features of the tabs, such as number, location and size, can be crucial factors for spiral-shaped battery cells. This paper presents a Li-ion battery cell model having a 3-dimensional spiral mesh involving a wound jellyroll structure. Further results and analysis will be given regarding impacts of tab location, number, and size.

Presentation that discusses Open Access (OA) and Open Educational Resources (OER) in light of the iniquities in scholarly communication that were made more apparent by the COVID-19 pandemic. This presentation discusses how OA and OER can address social justice concerns, improve scholarly communication, and facilitate equitable educational planning.

Presentation for developing student motivation with an emphasis in bilingual education or ESL students. It was presented as part of the Education for Hispanic Dual-Language Institute held at W. H. Adamson High School in Dallas, Texas on October 14, 2017.

This presentation gives an overview of Open Access including its definition, basic assumptions, open access registries, technology and trends, technological structure, policy frameworks, challenges and opportunities. It then applies this to the need for developing countries' contributions to global knowledge production and creating institutional initiatives.
