Background Vat photopolymerization (VPP) is used often in 3D printing for its ability to achieve high precision, excellent surface finish, and its capability to create complex structures with minimal support needs. Applications requiring high fidelity are best suited with the VPP process. However, two main challenges persist in the current VPP process....

Supply chains provide a network describing how resources move from a source to delivery for consumption by the end user. Supply chains also involve the components involved in production and transportation of the commodities being moved in the supply chain. There is a need for modeling links in a supply chain to estimate supply and demand and to ensure...

Background Utility pipes are a crucial component of public health and safety infrastructure, and it is critical to conduct regular inspections to ensure functionality. Currently, most pipes are inspected by human operators, which can pose safety concerns as well as inaccuracy and limited accessibility. As an alternative, in-pipe robots are increasingly...

­Background Electrolytic reduction of metal carbonates in molten salts at elevated temperatures have attracted attention over the past decade as a new way of producing various materials such as carbon materials and metal oxides. These carbon materials can be in various forms including carbon nanotubes, nanofibers, aggregates, amorphous carbon,...

The Caribbean region is considered a coral disease hotspot, with over 20 documented diseases and syndromes affecting over 20 species of corals. One motile marine pathogen family, Vibrionaceae, which is responsible for 50% of coral diseases, is strongly thermodependent, thus warming sea-surface temperatures, driven by pollution and global climate change,...

DNA and RNA nanostructures, e.g., DNA Origami, have great potential in biological applications, including extracellular matrix scaffolds and delivery vehicles for drugs and gene therapies. While folding DNA origami under physiological conditions is plausible, significant challenges and limitations remain. For example, isothermal annealing of DNA origami...

Background Unmanned vehicles such as unmanned aerial vehicles (UAVs) can be used for performing surveillance, reconnaissance, and exploration tasks in a wide variety of environments for military and civilian applications. A UAV may be manually controlled by a remote user, or may operate in a semi-autonomous or fully autonomous manner. Such UAVs can...

Background In the vast realm of advanced manufacturing technologies, continuous fiber manufacturing (CFM) has the capacity to fabricate structures characterized by their intricate complexity, lightweight, and exceptional properties. Most of CFM is developed based on the extrusion process, such as fused deposition modeling (FDM) and direct ink writing...

Background Polyurethane (PU) is a widely used plastic material that has excellent physical and mechanical properties. However, PU is difficult to recycle due to its complex chemical structure, making the effective disposal of PU waste a pressing issue. Current methods for PU disposal include incineration, which can release harmful toxins into the environment,...

As coastal or nearshore environments experience rising sea levels, warming and acidification in addition to pollution from upland watersheds, coastal cities, and industrial development, ecosystems are significantly impacted. While this is happening on a global scale, monitoring as well as solutions and mitigations need to be enacted at the local level....
