In-situ strain monitoring of concrete columns using multi-layer graphene-filled cementitious sensors
Self-sensing cementitious composites provide a promising solution for real-time structural performance assessment. In this study, 12 steel-reinforced concrete columns and 6 unconfined columns embedded with multi-layer graphene (MLGs) filled cement-based sensors (GCBS) were tested...

Dyella cornirhiza sp. nov., a Maize Rhizosphere Bacterium with Diverse Biosynthetic Potential
A novel bacterial strain, CR191T, was isolated from maize (Zea mays) rhizosphere soil. The strain is Gram-stain-negative, oxidase-positive, rod-shaped, non-motile, and aerobic. Phylogenetic analysis based on 16S rRNA gene sequences placed CR191T within the genus Dyella, with high...

Optimization and operation strategy for demand response in Park Energy Systems with Public Buildings
Abstract Public-building central air conditioning (CAC) systems provide substantial load flexibility because of their significant thermal inertia. However, existing optimization studies of park energy systems commonly represent them as conventional flexible loads, with insufficie...
