Ultrastructural aspects of fibre development during the stone groundwood process: New insights into derived pulp properties

A study was performed on stone groundwood (SGW) pulps produced on a pilot scale. The behaviour of selected juvenile and mature Norway spruce wood samples was investigated...

Keywords: Delamination, fibre development, fibrillation, juvenile wood, mature wood, microfibril angle (MFA), S1 layer, S2 layer, scanning electron microscopy (SEM), stone groundwood (SGW), ultrastructure of the cell wall

Exploring Scots pine fibre development mechanisms during TMP processing: Impact of cell wall ultrastructure (morphological and topochemical) on negative behaviour

A study was carried out aiming at understanding the fundamental reasons for different fibre behaviour exhibited by Norway spruce and Scots pine causing large energy consumption differences during thermomechanical pulping (TMP)...

Keywords: cell wall ultrastructure, defibration, fibre development, glucomannan, immunogold-EM, lignin, Picea abies, Pinus sylvestris, scanning electron microscopy (SEM), shives, S1 layer, S2 layer, transmission electron microscopy (TEM), thermomechanical pulping (TMP)

A comprehensive analysis of the relation of cellulose microfibril orientation and lignin content in the S2 layer of different tissue types of spruce wood (Picea abies (L.) Karst.)

A possible relation between cellulose microfibril angle and lignin content in the S2 layer was investigated by X-ray diffraction and cellular UV microspectrophotometry on spruce tissues [Picea abies] with different structural features and chemical composition...

Keywords: Cell wall assembly, cellulose microfibril angle (MFA), lignin content, S2 layer, spruce
