Reverse evolution of fluorine and side chains in bisisoindigo‐based copolymers enabling electron mobility exceeding 7 cm2·V−1·s−1

open access: yesFlexMat, EarlyView.
Abstract We report the design and synthesis of a series of bisisoindigo‐based donor–acceptor (D–A) copolymers, P4F18, P4F10, P2F18, and P2F10. By reverse evolution of fluorine substitution and side‐chain structure, we effectively tuned the frontier molecular orbital energy levels, intermolecular interactions, molecular self‐assembly, and thus charge ...

Gendered Pathways to Work–Family Balance and Their Consequences: Insights From Dual‐Career Faculty Couples

open access: yesHuman Resource Development Quarterly, EarlyView.
ABSTRACT This study examines gendered work–family balance (WFB) experiences among dual‐career academic couples at U.S. research‐intensive universities. By comparing faculty couples who shared the same or similar professional and family contexts, the study explores how gendered demands, challenges, resources, and strategies shaped distinct WFB outcomes.

Turning Water to Wine: An Analysis of Texas Wine Industry Water Management

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT The Texas wine industry is expanding in scale and reputation during a period when sustainability concerns are increasingly visible and valuable to grape growers and wine producers in Texas. Most vineyard hectarage in Texas is in the High Plains and Hill Country American Viticultural Areas (AVAs), which rely on regional aquifers for water. With

Variable Rate Irrigation: A Long‐Term Simulated and Field Data Analyses of Irrigation Practices, Field Variability, Economic Feasibility and Profitability

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Long‐term economic analyses of variable rate irrigation (VRI) strategies were performed compared with uniform irrigation management (UIM) in a reference production field using the AquaCrop model. Five strategies to trigger irrigation were as follows: (Field Capacity‐VRI, Driest Soil Trigger‐VRI, Water Mining‐VRI, Conventional Uniform ...
