    Solid State Battery Database Instruction Manual
    (2026) Petracci, M. Florencia; Albertus, Paul
    Despite thousands of annual publications on battery devices, standard reporting practices are distinctly absent, resulting in a patchwork of reported data that is difficult to analyze. To address this, we constructed a database of research-level solid-state batteries with an ontology-informed data framework reflected in 167 columns and populated with 245 batteries resulting in over 40,000 data-points. This project’s significance is threefold: (1) Our variables include materials, components, fabrication, and cell testing, whose combination is essential to describe and properly assess a solid-state battery. (2) Our inclusion of “Not Applicable” and “Not Reported” values enable analysis of reporting practices and insights on ”missing data” in battery publications. (3) We present a structure for battery data with well-defined variables, facilitating formatted reporting. Key applications discussed include advanced search workflow employing numerical and categorical criteria for experiment design, streamlined visualization for various actors and utilizations, and a training set for AI paper-data extraction.

    Escaping History in the Gateway to the West
    (University of Maryland, 2026-06) Meggitt, Finn
    Escaping History in the Gateway to the West reflects upon contemporary narratives around the decline and condition of St. Louis. A region defined nationally by its decline, but the reasons cited by both locals and outsiders for the decline are a combination of vague, categorically natural historical processes. The piece uses an analysis of modern jobs, housing, and demographic data post-Great Recession, a history of the region’s racial politics, and a quantitative mapping of white flight and the spatialization of race in the St. Louis region from the Great Depression to the modern era to offer an answer to the region’s contemporary decline. The author argues the entire region, not just the urban core, post-pandemic has begun to experience a historically significant decline because of the region’s racial politics based on analysis which shows every city, suburb, and exurb in the region is experiencing white flight from the region. The region’s racial politics came to the national stage in 2014 after the murder of Michael Brown for a reason, the city has a unique politics and social structure because of its position as a city which is neither north nor south, while being the gateway to the west.

    Freight Commuters? Evaluating the Feasibility of Integrated Passenger-Freight Transportation Through a Station-Level Screening Framework on Maryland's MARC System
    (University of Maryland, 2026-06) Aghili, Sayed Homayoon
    Integrated Passenger–Freight Transportation (IPFT) has gained renewed attention as a strategy to improve rail system efficiency, reliability, and sustainability without extensive new right-of-way construction. However, feasibility and public benefit vary substantially across shared-use corridors, particularly at station nodes where operational, spatial, and land-use factors intersect. This study proposes and applies a station-level, GIS-based screening framework to evaluate IPFT feasibility along Maryland’s MARC Camden and Brunswick Lines, which operate in proximity to CSX freight corridors. Using a multi-criteria approach, stations are assessed across five dimensions: platform separation, track complexity, right-of-way flexibility, adjacent land-use compatibility, and accessibility. Network-based walking and driving service areas and point-of-interest data are used to capture station-area context and access conditions. Results reveal highly uneven IPFT feasibility across stations, with a limited subset exhibiting strong alignment across operational and spatial dimensions. The findings support a selective, pilot-oriented approach to passenger–freight integration and demonstrate the value of early-stage screening tools for future-ready rail planning. The study contributes a transparent and replicable framework that can inform corridor development, investment prioritization, and coordinated passenger–freight strategies.

    The Geography of School Communities: How Land Use and Neighborhood Form Shape Elementary Attendance Zones
    (University of Maryland, 2026-06) Bochynski, Michael
    School attendance zones are often treated as administrative boundaries, yet they contain distinct neighborhood histories, housing patterns, and socioeconomic conditions that shape the lived experiences of students and families. This article analyzes demographic and parcel level land use patterns across four elementary school attendance zones in Chillum, Maryland (Carole Highlands, Lewisdale, Ridgecrest, and Rosa L. Parks) to examine how built environment characteristics align with social vulnerability. Using area weighted allocation of Census indicators and parcel level land use classification, the analysis reveals substantial variation in poverty, linguistic isolation, housing typologies, and land use composition across zones. Carole Highlands exhibits the highest poverty rate and the most mixed residential–commercial environment, while Lewisdale is dominated by single family housing and has the lowest poverty rate. Ridgecrest and Rosa L. Parks fall between these extremes, each with unique built environment signatures. These findings highlight the importance of treating attendance zones as meaningful planning geographies and illustrate how spatial analysis can support community school planning under Maryland’s Blueprint for the Future. By integrating demographic and physical landscape data, the article offers a place based narrative that connects neighborhood form to educational equity and community well being.
