Multiscale characterization of carbon fiber-reinforced epoxy composites
… measured using acoustic emission. Additional characterizations of the epoxy mechanical properties, thermal properties, and degree of cure were also performed. The presence of oxygen and nitrogen on the fiber surface significantly increased adhesion to the matrix material, while the specific …

Unsupervised Signal Deconvolution for Multiscale Characterization of Tissue Heterogeneity
Characterizing complex tissues requires precise identification of distinctive cell types, cell-specific signatures, and subpopulation proportions. Tissue heterogeneity, arising from multiple cell types, is a major confounding factor in studying individual subpopulations and repopulation dynamics. …

Multiscale characterization of thermoacoustic response and fatigue failure of aerospace structures
Sustained hypersonic flight has presented a complex problem to researchers and structural designers in recent decades as it has been seen to induce failure of thin aerospace panels in modes that had not been previously accounted for. These new and unaccounted for failure modes are attributed to the …

Multiscale characterization of mechanical and fracture properties of cortical bone specimens
Bone is a hierarchical material with multiple length scales ranging from mineralized collagen fibrils at the nanoscale, single lamella at the sub microscale, lamellar structure at the microscale, osteons at the mesoscale to a whole bone at the macroscale. Several fracture testing methods are …

Multiscale characterization of mechanochemical reactions in mechanophore-crosslinked polymers under shear loading
Inspired by mechanotransduction, new strategies are employed to impart productive mechanochemical response to polymeric materials. These mechanoresponsive materials possess the ability to respond to an applied global force through a local chemical reaction. In synthetic polymers, mechanochemical …

Nano-Materials By Design and Their Applications in Infrastructure
… and physical laws. To achieve this goal multiscale characterization and modeling is needed to deliver our thorough application effectively. The main objective in this research is to implement multiscale characterization of the nano-micro-meso-macro properties of advanced polymeric and …

Multiscale Insights into Molecular Interfaces: STM Imaging and Ultrafast Laser-Induced Dynamics
This thesis explores the multiscale characterization of molecular self-assembly and ultrafast dynamics at interfaces by integrating high-resolution scanning tunneling microscopy (STM) with advanced spectroscopic and ultrafast laser techniques. Focusing on cyclopentadienyltricarbonylmolybdenum dimer …

Macro and nanocreep of self-consolidating concrete
… macro and nanoscale creep experiments used for a multiscale characterization of creep of SCC. Macrocreep experiments placed different SCC and normal vibrated concrete (NVC) mixes under sustained compressive and tensile stress to compare creep of SCC with NVC. Creep of SCC was compared with NVC …

Irradiation effects on geopolymer and additively manufactured 316H stainless steel and porosity in equine hoof wall
… irradiation conditions using 0.5 MeV H+ ions. Multiscale characterization showed AM SS exhibited higher initial dislocation densities, reduced microstrain at lower doses (0.6 dpa), and more stable mechanical behavior under irradiation than conventional SS. Microhardness testing revealed a …

MULTI-SCALE MECHANICS OF COMPOSITE SANDWICH STRUCTURES WITH BIOLOGICALLY INSPIRED FIBER REINFORCED FOAM CORES: A POTENTIAL TEMPLATE FOR DEVELOPING MULTIFUNCTIONAL STRUCTURES
This dissertation describes a novel multi-scale characterization and modeling approach for developing bio-inspired composite sandwich structures. The source of bio-inspiration was chosen to be Palmetto wood, a naturally occurring porous composite material with macrofiber reinforcement. …
