Abstract:
This study employs 3D X-ray micro-computed tomography (micro-CT) imaging to quantitatively analyze rebar corrosion in reinforced concrete exposed to a chloride-induced environment. Chloride-induced corrosion is a critical issue in reinforced concrete structures, leading to structural deterioration and potential safety hazards. Through non-destructive micro-CT imaging, we investigate the spatial distribution and extent of corrosion damage within the concrete matrix and along the rebar interface. Our results provide detailed insights into the corrosion process, including the formation of corrosion products and their impact on concrete integrity. This research enhances our understanding of corrosion mechanisms in reinforced concrete and informs strategies for mitigating corrosion-induced deterioration in infrastructure systems.

Abstract:
This study investigates the enhanced mechanical and impact properties of engineered cementitious composites (ECC) reinforced with polypropylene (PP) fibers when subjected to elevated temperatures. Engineered cementitious composites offer improved ductility and strain-hardening behavior compared to traditional cementitious materials, making them promising for various structural applications. We examine the influence of PP fiber reinforcement on the performance of ECC under elevated temperatures, focusing on mechanical strength, toughness, and impact resistance. Through experimental analysis and characterization, we elucidate the effects of fiber content and temperature exposure on the microstructural and mechanical properties of ECC. The findings contribute to understanding the behavior of ECC reinforced with PP fibers in fire conditions, thereby informing the development of resilient and durable construction materials for high-temperature environments.

Abstract:
This study presents a novel approach for engineering muscle constructs by integrating multiple scales of materials and techniques. Specifically, we describe the fabrication of muscle constructs using a combination of polyethylene glycol (PEG) hydrogel micro-patterning on an electrospun polycaprolactone (PCL) matrix functionalized with gold nanoparticles (AuNPs). This multiscale approach allows for precise control over cellular organization and microenvironmental cues within the muscle constructs. We investigate the effects of PEG hydrogel micro-patterning and AuNP functionalization on cellular behavior, including proliferation, differentiation, and contractile function. Through comprehensive characterization, including microscopy, biochemical assays, and mechanical testing, we demonstrate the effectiveness of this approach in engineering muscle constructs with enhanced functionality. Our findings offer valuable insights into the design and optimization of multiscale-engineered muscle constructs for applications in regenerative medicine and tissue engineering.
