Sedimentology and Stratigraphy of a Matrix-Poor to Matrix-Rich Depositional Continuum in Proximal Basin Floor Strata, Upper Kaza Group, Windermere Supergroup, B.C., Canada.
Matrix-rich strata (20-70% mud matrix) have been increasingly recognized in deep-marine systems. These beds are thought to be deposited from mud-rich flows in a distal basin-floor setting; however they remain poorly understood, partly because details of lateral lithological changes are poorly …

Mechanical enhancement of woven composites with radially aligned carbon nanotubes (CNTs) : investigation of Mode I fracture toughness
… complexity and challenging failure modes. Matrix-rich regions at ply interfaces especially are susceptible to damage and matrix cracking, leading to delamination and a reduction of mechanical properties. Several manufacturing solutions such as stitching, z-pinning, and braiding have been …

On iso- and nonisothermal crack problems of a layered anisotropic elastic medium
… technique and the flexibility/stiffness matrix formulation, the current mixed boundary value problems are reduced to solving a set of simultaneous singular integral equations with Cauchy-type kernels. The crack·tip stress intensity factors are then defined in terms of the solution of the …

Catalysis and manufacturing of two-scale hierarchical nano- and microfiber advanced aerospace fiber-reinforced plastic composites
… vehicle structures. By reinforcing the weak matrix-rich regions between individual fibers and plies, the circumferential growth of aligned carbon nanotubes (A-CNTs) on carbon microfibers (CFs) enables new composites with improved strength, toughness, electrical and thermal properties. While …

An experimental investigation of the material response of graphite/polyphenylene sulfide
… included warping of unidirectional panels, dense matrix cracking in all multi-directional laminates, and local matrix rich and matrix poor regions. The predominately observed damage mechanism occurring as a result of applied mechanical load was delamination. Comments on the ability of each NDT …

Sedimentology and Stratigraphy of Glacial Lake Souris, North Dakota: effects of a glacial-lake outburst
… have been grouped into three lithofacies: 1) matrix-rich gravel, commonly with lignite, that generally occurs at the base of the outburst sediments; 2) matrix deficient gravel, generally without lignite, that occurs near the ground surface adjacent to the Souris spillway; and 3) sand, the most …

A Dual-Domain Peptide Strategy for Targeted Regenerative Repair
… regeneration through coordinated extracellular matrix targeting and immune modulation. The peptide construct incorporates a collagen-binding domain (CBD) to spatially localize bioactivity within matrix-rich tissues. Two alternative CBDs are investigated: a DMP1-derived acidic motif (CBD1: …

Petrology and petrography of samples from two Algoa Basin cores
… are carbonate cemented are relatively free from matrix, while those which are uncemented are matrix-rich. This latter situation can be ascribed to the breakdown, after burial, of the commonly occurring rock fragments which frequently constitute about one-third of the sandstones. The problem of …

The Use of Dynamic Fluid Flow Strategies for Bone Tissue Engineering Applications
… to stimulate the synthesis of an extracellular matrix rich in osteogenic and angiogenic factors that are envisioned to guide bone healing in vivo. Fluid flow, which exerts a hydrodynamic shear stress on adherent cells, has been identified as one of the strongest stimuli on bone cell behavior. It …

Manufacturing and fracture of hierarchical composite materials enhanced with aligned carbon nanotubes
… through-thickness properties that occur due to matrix-rich regions, including those found at interlaminar ply interfaces, that are prone to delamination and lead to overall reductions in mechanical properties. Existing technologies such as stitching, z-pinning, and braiding provide …

Development of multifunctional polymer composites with self-healing capability
… This Thesis aims to develop a thermoplastic matrix possessing self-healing properties using polyamide 6 (PA6), which is the most commonly utilized thermoplastic polymer in the production of thermoplastic composites. As there is a lack of systematic investigation on this particular research …
