Natural nacre, which consists of almost 95 vol% inorganic content (calcium carbonate) and 5 vol% elastic biopolymers, possesses a unique combination of remarkable strength and toughness, which is attributed to its hierarchical nano-/ microscale structure and precise inorganic–organic interface. Inspired by the intrinsic relationship between the structures and the mechanical properties lying in ...
In this work, different aspects on the re-use of wood based fibres have been studied, focusing on ink detachment of flexographic ink from model cellulose surfaces and changes in porous structure of kraft fibres following different treatments. New model systems for evaluation of ink detachment and ink-cellulose interactions were used. Ink detachment was studied using Impinging jet cell equipment...
Diatom frustules (the hard and porous cell wall of diatoms) are created under the control of biomolecules (silaffins, silacidins, and long-chain polyamines) at close to physiologic conditions. The mechanism of biosilica formation was traditionally based on the ability of zwitterionic water-soluble proteins to create macromolecular assemblies for silica polymerization. Recent discoveries of wate...
Cadmium chalcogenide quantum dots (QD’s) were synthesised using a single source approach while zinc oxide QD’s were obtained by a colloidal technique. In both situations the dots were surface capped with tri-octylphosphine oxide (TOPO) hence leading to nanodispersed systems in organic solvents such as toluene. The organically capped QD’s (CdSe, CdS and ZnO) were used as building-units to fabric...
