1. Thermally Modified Timber : Novel Aspects of Bending Behaviour Towards Grading and Structural Applications
Sammanfattning : Thermally modified timber (TMT) has gained market share in Europe as an environmentally friendly and durable building material. Unfortunately, TMT products are currently prohibited for use in structural applications as there is insufficient data to estimate the loss in strength due to thermal modification. LÄS MER
2. Modified kraft pulping
Sammanfattning : .... LÄS MER
3. Hydrophobically Modified Polymers. Rheology and Molecular Associations
Sammanfattning : Structure- property relationships and thickening mechanism in aqueous solution of two hydrophobically modified polymers (HM-P) with different architecture have been investigated. The two polymers, hydrophobically modified ethyl hydroxyethyl cellulose (HM-EHEC) and hydrophobically modified polyethylene glycol (HM-PEG), are commonly used as associative thickeners in the paint industry.

4. Investigation of Modified Cellulose and Starch via Hydrolysis and Mass Spectrometry
Sammanfattning : Starches and celluloses can be chemically modified in order to affect their physiochemical properties. Modification of these carbohydrate polymers entails derivatising their free hydroxyl groups with functional groups. LÄS MER
5. Wettability of modified wood
Sammanfattning : Despite many excellent properties of wood which make it suitable for many applications, it suffers from a number of disadvantages limiting its use. For instance, modification is needed to reduce water sorption and to improve decay resistance, dimensional stability and weathering performance. LÄS MER
