Anisotropic Shear Properties of Organic Interfaces in Bio‐composite Materials

open access: yesAdvanced Functional Materials, EarlyView.
A novel cantilever design enables direct probing of shear properties at single organic interfaces within biocomposite prismatic ultrastructures. By decoupling lateral and torsional shear responses, the method reveals isotropic behavior in Atrina vexillum and pronounced anisotropy in Unio pictorum.

A Termite‐Inspired Alternative to Cement

open access: yesAdvanced Functional Materials, EarlyView.
A termite‐inspired composite of clay, cellulose, and lignin forms a dense fibrous network with concrete‐like strength (32 MPa) and superior elasticity, processed at ambient temperature. Abstract Clay combined with organic materials is used by termites as a strong and durable construction material for their mounds with minimal environmental impact. Here,

Effect of particle size on the surface properties and morphology of ground flax [PDF]

open access: yes, 2013
Flax fibers were ground with a ball-mill and four fractions with different size ranges were collected by sieving. These were tested for water sorption, degree of polymerization (DP), copper number, hydroxyl number and analyzed by X-ray diffraction (XRD),

4D Mapping of ZIF Biocomposites for High Protein Loading and Tunable Release Profiles

open access: yesAdvanced Functional Materials, EarlyView.
Systematic four‐dimensional mapping of zeolitic imidazolate framework biocomposites reveals how precursor ratios, total concentration, and washing define crystalline phase, protein loading, and release kinetics. This comprehensive study identifies conditions yielding record loading (∼85%) and precise phase–property correlations.

Effect of fibre treatments on interfacial shear strength of hemp fibre reinforced polylactide and unsaturated polyester composites [PDF]

open access: yes, 2011
Surface treatment of hemp fibres was investigated as a means of improving interfacial shear strength (IFSS) of hemp fibre reinforced polylactide (PLA) and unsaturated polyester (UPE) composites. Fibres were treated with sodium hydroxide, acetic anhydride,
