Swelling and dissolution mechanisms of natural cellulose fibres [PDF]

, 2007
One of the limitations to the use of cellulose is the difficulty involved in the processing and fabrication because of the specific structure of the fibres. In most cases, cellulose cannot be used in its natural form. It has to be dissolved. The focus of

Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

Advanced Engineering Materials, EarlyView.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

Cellulose coating and chelation of antibacterial compounds for the protection of flax yarns against natural soil degradation. [PDF]

, 2017
Natural cellulosic fibres such as flax fibres present interesting mechanical properties as well as biodegradability, and by-products, such as short flax fibres, could be used to produce geotextiles to stabilise soils. Today, geotextiles are often made of
