Biomaterials
The course introduces fundamental aspects associated with synthesis, properties, processing/fabrication and application of materials (cellulose, hemicellulose, lignin) derived from or associated with bio-entities. Included in the course are many relevant fundamental details that link factors such as bonding, structure and defects in fibres, processing parameters and microstructures (crystallinity and morphology of cellulose) to the properties and mechanics of biomaterials. The course focuses on biomaterials with broad applications beyond energy, optics, agricultural sector, chemical, pharmaceutical, medical or clinical uses.
The couse is offered only if a sufficient number of students is registered.
Elective for students in the 5th semester of the BSc in Sustainable Economy and Bioproduction, Bachelor in Biology and a mandatory coruse in the semesterpackage Biorefinary.
The course can be offered to single course students, but be aware of the course's prerequisites.
The course is base at campus Steinkjer, but may also be digital/online. Lectures may be in English.
The course provides the student with knowledge about:
Knowledge
- Broad knowledge and understanding of composition and properties of cellulose, hemicellulose, lignin and extractives
- Technologies used in feedstock fractionation
- Chemical reactions in the most important fractionation methods of plant biomass to its constituents
- Chemical characterization of lignocellulosic compounds using chemical methods.
- Knowledge of research and development work in fractionation of lignocellulosics.
- Recognize technical challenges used in manufacturing of different biomaterials and determine the optimal application considering composition and physicochemical properties of lignocellulosics
Skills
The course should enable the students to:
- Distinguish the special nature of plant-based fibres and assess how the properties affect their applicability
- Develop an ability to intercorrelate a structure and physicochemical properties of lignocellulosic materials
- Point out the main bottlenecks in modern applications of cellulose-based fibres, fibre components, hemicellulose, lignin, and extractives
- Choose correct analytical methods for assessing certain properties of lignocellulosic materials and their applications
- Develop experimental skills to fractionate lignocellulose to its main constituents (cellulose, hemicelluloses, lignin, extractives) and characterize their chemical structure by chromatography and spectroscopy.
General competence
After completion of the course the students should gain general competence in:
- the physical and chemical distinctions between natural fibres, regenerated fibres, and nanofibres
- the basic structures, properties and functions of common hemicelluloses and lignins and structure-property relationship to cellulose-based fibres
- master the morphology of the native cellulose microfibril and acknowledge how it affects nanocellulose preparation and properties
- the major obstacles and difficulties in cellulose dissolution and regeneration through basic laws of physical chemistry
- the main pathways to chemical modification of lignocellulosic materials and assessment of biomaterials’ quality using chemical analytical methods
- correlation of composition and physicochemical properties of lignin, hemicellulose, and extractives with the pathway to apply biomaterials in industry
