报告摘要1：

We demonstrateproteins as compatibilizers and eco-friendly dispersant of renewablenanoparticles, including cellulose nanofibrils and nanocrystals which promotecontact adhesion. Along with other nanoparticles based on chitin, a range ofpossibilities is unveiled to demonstrate the generic effect of theself-assembly of the particles toward high noncovalent adhesive shear strength.The adhesion develops following evaporation-induced self-assembly duringgel-to-solid transition, leading to multiscaled and ordered superstructuredlamellae. The reversible assembly of the adhesive is highlighted for itspotential in reducing damage in high-strength but brittle constructionelements. The results point to the role of the high axial aspect nanoparticles,ultimately acting as key component of systems similar to the bioadhesives foundin nature that utilize high order and hierarchical assemblies. A furtherextension of the work considered the interfacial interactions betweennanochitin and proteins (BSA, lysozyme in polymeric and amyloid forms), whichact as bio-cements with remarkable properties. The results are rationalized inthe context of current efforts to standardize the measurement of adhesivestrength and bond formation. Overall, the proposed biobased systems areexpected to expand current developments in the design of fully green,cost-effective, and aqueous-based adhesives.

报告摘要2：

Reducing theenvironmental impact of the chemical industry requires a shift towardrenewable, functional materials that align with circular economy principles andglobal sustainability goals. Forests and oceans offer abundant sources ofstructurally and chemically diverse biopolymer such as cellulose, chitosan,alginate, lignin, and tannins. These materials can be transformed intohigh-performance materials for advanced manufacturing and environmentalremediation. This seminar explores how such natural building blocks can bere-engineered for modern applications through three interconnected themes.:

The first focuses on theuse of biomaterials as functional crosslinkers for UV-curable hydrogels,enabling the development of 3D printable networks for biomedical applications.The second explores how surface-functionalized biobased nanoparticles canstabilize emulsions and enable novel liquid-in-liquid 3D printing strategies,generating conductive filaments and dynamic structures. The third highlightsthe use of bio-derived scaffolds for sorbent materials and aerogels capable ofwater harvesting and pollutant removal.

Together, these projectsdemonstrate a materials-by-design approach using renewable resources to replacefossil-based systems, while offering new pathways for responsive,reprocessable, and environmentally beneficial technologies.

报告摘要3：

Biomass materials possess inherent advantagesin the development of biomimetic materials and offer an essential pathway forachieving high-value utilization of biomass. However, the intrinsically complexstructure of biomass nanomaterials impedes precise structural manipulation,material performance optimization, and the further development of high-valueapplications. To address these challenges, we highlight recent advancements inbiomass technology through colloidal control, particularly by utilizinginterfacial confinement environments to manipulate biomass materials and enabledynamic, biomimetic functionalization precisely. This presentation will covertwo interfacial regulation strategies for biomass materials. The first involvesthe precise control of electrostatic assembly of nanocellulose and nanochitinat the aqueous two-phase interface, enabling the on-demand construction ofadvanced functions such as selective mass transfer, controllable sub-surfacemigration, and liquid-in-liquid 3D printing. Collectively, we establish amicrocapsule reactor system characterized by self-migration,self-initiation, and self-termination. In the second strategy, livingmicroorganisms are regulated at the water-oil interface to synthesizecellulose, leveraging the continuous mass transfer properties of the two-phasesystem to enable multiphase biomanufacturing. This approach facilitates theconvenient and efficient construction of multilayer hydrogels, porousmaterials, and core-shell microcapsule structures. Such dynamic biomimeticstrategies for biomass provide new theoretical directions and technicalpathways for developing green new material systems that combine high conversionefficiency with high added value.
