Chitin nanofibrils (NCh, ∼10 nm lateral size) were produced under conditions that less severe compared to those for other biomass-derived nanomaterials and used formulate high internal phase Pickering emulsions (HIPPEs). Pre-emulsification followed by continuous oil feeding facilitated a "scaffold" with elasticity, which arrested droplet mobility coarsening, achieving edible oil-in-water volume fraction as 88%. The stabilization ability of rodlike NCh originated from the restricted breakage...

Phase change materials (PCMs) enable passive thermal management by minimizing energy waste. However, a limitation of organic PCMs is their low conductivity, which leads to uneven phase transitions.

Direct ink writing (DIW) is a customizable platform to engineer complex constructs from biobased colloids. However, the latter usually display strong interactions with water and lack interparticle connectivity, limiting one-step processing into hierarchically porous structures. We overcome such challenges by using low-solid emulgel inks stabilized chitin nanofibrils (nanochitin, NCh). By complementary characterization platforms, we reveal NCh structuring spatially controlled...
