Investigation of ammonium polyphosphate dilution with ground eggshells and lignin through the study of natural fibre composite flammability

Fire and Materials, Volume 47, Issue 1, Page 28-50, January/February 2023., 2023
Summary The interactions of Calcium carbonate (e.g., eggshell powder) and Lignin with ammonium polyphosphate (APP) when used as fire retardants were investigated. Three mixing ratios ‐ 1:3, 1:1, and 3:1, were used with natural fibre reinforced composites containing a hemp mat and an epoxy matrix manufactured using a light resin transfer moulding (L‐RTM)

Moisture‐Dependent Vibrational Dynamics and Phonon Transport in Nanocellulose Materials

Advanced Materials, EarlyView.
Uptake of water in cellulose play an important role in modulating the structure and phonon transport. This study reports how moisture‐dependent structural modification relates to the vibrational dynamics and phonon transport and scattering of nanocellulose using inelastic neutron scattering and wide angle X‐ray scattering.
