Structural Dynamics of Complex Fluids Subjected to Planar Extensional Flow Studied Using In Situ X-ray Scattering

Description:

Complex fluids are ubiquitous, from natural materials to manufactured products. Understanding their behavior under flow is vital for engineering these materials. Extensional flow, despite being industrially relevant and often producing dominant impacts upon complex fluids, is an underserved topic compared to shear flow due to a lack of reliable apparatuses...

Engineering Scalable Microenvironments to Enhance Ex Vivo Megakaryocyte Production and Platelet Release

Description:

Currently, platelet transfusions, possessing profound clinical importance in the clotting of blood and healing of wounds, are entirely derived from human volunteer donors. This approach is limited by a 5-day shelf life, the potential risk of contamination, and differences in donor/recipient immunology. In vivo, platelets are formed when bone marrow...

Dynamic Chemistries in Non-linear Polymer Systems: From Applications for Sustainability to Fundamental Theories

Description:

Conventional polymer network materials, e.g., rubber tires, cannot be efficiently recycled for high-value applications because of their permanent network structures. Therefore, at the end of use, none or only a small fraction of the economic value can be recovered from these materials. Scrapped tires demonstrate well this issue along with...

The Effect of Reducible Metal Oxides on the Structure and Activity of Supported Vanadium Oxide Catalysts Prepared by Atomic Layer Deposition for Cyclohexane Oxidative Dehydrogenation

Description:

Supported vanadium oxide materials have been extensively studied for alkane oxidative dehydrogenation (ODH) reactions due to their high activity and selectivity. The catalytic activity of supported VOx materials is influenced by the surface coverage of VOx sites and hence the distribution of V=O, V-O-V, and V-O-S (S, support) bonds. The...

Continuum modeling of multidisperse and polydisperse granular materials in transient and developing flows

Description:

Segregation of polydisperse granular materials remains to be a challenging problem in many industrial processes. However, most studies have focused either on bidisperse (two different particle size species) materials, which are not representative of most real mixtures, or on polydisperse materials in an idealized simple geometry. Additionally, most studies have...

Pushing the Limits on Metal–Organic Frameworks as Catalyst Supports: Small Hydrocarbons Reactions over NU-1000-Supported Catalysts

Description:

Heterogeneous catalysts based on metal oxides are of significant interest for many industrial chemical reactions. These catalysts, however, often suffer from ill-defined structures that preclude better understanding of the surface phenomena. Thus, structurally well-defined catalysts have received growing attention by making it feasible to understand the kinetics and reaction mechanisms....
