- Description:
- Since their introduction nearly a century ago, protein vaccines and therapeutics have revolutionized our ability to prevent and treat human disease. However, existing production processes for biopharmaceuticals are technically complex and rely on living cells, which necessitates highly centralized manufacturing in large-scale production facilities, specialized equipment, and cold-chain distribution. With...

The average properties of polymer materials with substantial specific interfacial area, e.g., ultrathin films, nanorods, and polymer nanocomposites, often deviate significantly from the bulk responses. Much of the past research has focused on systems in which free...

- Description:
- Molybdenum oxides and sulfides are earth-abundant materials known to catalyze a wide array of reactions, including dehydrogenation, hydrotreating, and higher alcohols synthesis. In particular, alkane and alcohol dehydrogenation are of interest given recent shifts in the energy landscape away from traditional petroleum feedstocks and towards natural gas and renewable energy...

- Description:
- Metal-organic frameworks are crystalline, nanoporous materials formed by metal nodes connected by organic ligands. MOFs represent an exciting approach to materials design where a material with desired properties can be made by choosing the compatible nodes, linkers and topologies independently. MOFs are highly porous and have high surface areas...

- Description:
- Protein-based biomaterials are widely used in biomedical applications and mechanical support because of their novel structural flexibility, biocompatibility and mechanical properties. Protein-based biomaterials outperform traditional synthetic materials in various environments as traditional materials lack the diverse chemical functionalities that proteins offer. Novel bioinspired techniques such as directed evolution offer the...

- Description:
- Conventional polymer networks are composed of strong, fixed covalent cross-links. The covalent cross-links render polymer networks with outstanding mechanical properties, heat stability, and chemical resistance; however, they also prevent polymer networks from being decross-linked or/and recycled into similar-value products at the end of their life, leading to environmental and economic...

- Description:
- Protein-protein interactions are ubiquitous in living systems, and mediate important cellular processes from decision making to immunity against pathogens. Furthermore, protein-protein interactions are key to many protein therapeutics, pathogen diagnostics, and numerous synthetic biology applications. As a result, there has been significant effort to develop methods to express potential protein...

- Efficient and sustainable utilization of global resources represents a grand but achievablechallenge. By leveraging biology, we can transform abundant, but recalcitrant resources like lignin to products ranging from fuel to medicine to polymers. Efforts to do so are expansive, but challenges remain, due in no small part to the difficulty...

- Description:
- Conventionally cross-linked polymers, which comprise the vast majority of commercial thermosets, cannot be decross-linked after curing or flow upon heating. Therefore, they cannot be effectively recycled into high-value products at end-of-life. Their lack of recyclability is due to the permanent cross-links, which restrict the flow of the chains in the...
