1. Synthesis and characterization of a greener poly(vinyl acetate) adhesive
University essay from KTH/Fiber- och polymerteknologiAbstract : To produce a greener adhesive is always an issue of concern to the commercial market and global environment. The environmental request for producing greener and bio-based adhesives leads to an increased awareness of replacing fossil-based components in adhesives with bio-based alternatives. READ MORE

2. Reaction Mechanism between Chitosan and Cerium(VI) Ammonium Nitrate for Production of a Greener Poly(Vinyl Acetate) Adhesive
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : Poly(vinyl acetate) (PVAc) has a major application as an indoor wood adhesive. Low water stability is however, one of the greatest drawbacks of PVAc. By grafting PVAc from a chitosan (CS) backbone (CS-graft- PVAc) water stability of adhesive is increased while good mechanical and adhesive properties are retained. READ MORE

3. Polyvinylalcohol-carbazate (PVAC) inhibits bacteria growth
University essay from Uppsala universitet/Institutionen för kvinnors och barns hälsaAbstract : Abstract Introduction This study evaluated the effect of the polymer polyvinylalcohol-carbazate (PVAC) on the bacteria Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis and Pseudomonas aeruginosa. PVAC is a polymer with a carbazate moiety that neutralizes free aldehydes and has shown great promise in stabilizing erythrocytes during long term storage. READ MORE

4. Atomistic Modeling of Amorphous Energetic Materials
University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysikAbstract : A majority of research within the field of energetic materials have been centered around the stable crystalline phase, whilst there has been less about the amorphous phase and the implications of these types of material. In this study, Molecular Dynamics simulations with the General Amber Force Field (GAFF) is used to predict fundamental properties of the nitramine explosives HMX and CL-20 in the amorphous phase.

5. Diagonal compression of Cross-Laminated Timber
University essay from Luleå tekniska universitet/TräteknologiAbstract : Twelve blocks of Cross Laminated Timber (CLT) were built, tested and simulated. Three types of blocks with different laminate directions in the middle/second layers were used: 0/30/0, 0/45/0 and 0/90/0. Simulations with three-dimensional quadratic orthotropic linear elastic finite elements were conducted. READ MORE
