About the webinar

In this webinar, you’ll delve into the fascinating world of nanopolysaccharide-based gels for Direct Ink Writing (DIW). DIW inks possess specific properties, including shear-thinning behavior, high storage modulus, and high yield stress.

Nanopolysaccharides, such as wood-derived cellulose nanofibers (CNF) and crab-derived chitin nanofibers (ChNF), are particularly well-suited for this purpose. They readily form robust, water-based networks.

Dr. Bai and his team are at the forefront of research on nanopolysaccharide-based multiphase systems for DIW. Join this webinar to hear Dr. Bai present their work on:

  • Emulsion-Based Multiphase Inks: The team meticulously designed inks that enhance printability even at low solid content. These emulgel systems incorporate specific components to prevent shrinking and deformation after drying.
  • Skin-Bearing Architecture: Using the designed emulgel system, the team achieved a skin-bearing architecture through one-step DIW. This process involves spontaneous phase-separation during printing.
  • Robustness and Applications: The study demonstrates that DIW significantly improves the robustness of printed emulgel-based objects. These materials find practical applications, such as cell culturing, showcasing the efficiency and versatility of DIW in designing multifunctional materials.

About the speaker

Dr. Long Bai is currently a professor at Northeast Forestry University (NEFU), China, starting from 2021. He obtained his PhD degree in biomass material and engineering from NEFU at 2016, and then joined Prof. Orlando Rojas’s group as a postdoctoral research fellow at Aalto University (Finland) and The University of British Columbia (Canada).

His research mainly focuses on connecting fundamental and applied sciences using nanopolysaccharides-based multiphase systems to facilitate the widespread implementation of renewable, sustainable materials and processes under bioeconomy framework.

He has authored peer-review papers in journals of Chemical Reviews, Nature Sustainability, ACS Nano, Advanced Functional Materials, etc. He has received several grant funds supported by the National Natural Science Foundation of China, etc.
