   Abstract : Due to climate change and plastic pollution, there is an increasing demand for bio-based materials with similar properties to those of common plastics yet biodegradable. In this respect, cellulose is a strong candidate that is already being refined on a large industrial scale, but the properties differ significantly from those of common plastics in terms of shapeability and water-resilience.

4. 12. Adhesion in the wheel-rail contact under contaminated conditions

   Author : Yi Zhu; Ulf Olofsson; Ines Lopez Arteaga; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesion; wheel-rail contact; contaminants; rough surfaces;

   Abstract : Railway vehicles require a certain level of adhesion between wheel and rail to operate efficiently, reliably, and economically. Different levels of adhesion are needed depending on the vehicle running conditions. READ MORE

5. 13. Adhesion-related interactions of Actinomyces and Streptococcus biofilm bacteria

   Author : Mirva Drobni; Nicklas Strömberg; Karl-Eric Magnusson; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biofilm; Actinomyces; Streptococcus; adhesion; Cariology; Cariologi;

   Abstract : Adhesion of bacteria is a key event in biofilm formation and is mediated by bacterial adhesins recognising host or bacterial partner receptors. In oral biofilm formation, primary Actinomyces and Streptococcus colonizers adhere to salivary pellicle proteins such as proline-rich proteins (PRPs) as well as to mucosal surfaces. READ MORE

6. 14. The Influence of Molecular Adhesion on Paper Strength

   Author : Malin Eriksson; Lars Wågberg; Orlando Rojas; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi;

   Abstract : This thesis deals with the influence of molecular adhesion on paper strength. By combining the use of high-resolution techniques and silica/cellulose surfaces, with various fibre–fibre and sheet testing techniques, new information regarding the molecular mechanisms responsible for paper strength has been obtained.

7. 15. Neisseria gonorrhoeae and Lactobacillus from initial adherence to effects on human cells

   Author : Katarina Vielfort; Helena Aro; Bernt Eric Uhlin; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neisseria gonorrhoeae; Lactobacillus; adhesion; cell cycle; DNA damage; Neutrophils; molekylärgenetik; Molecular Genetics;

   Abstract : The causative agent of gonorrhoea Neisseria gonorrhoeae (gonococcus) colonises the urogenital tract epithelia. The vaginal tract microbiota of healthy females is dominated by Lactobacillus species. In paper I, the ability of lactobacilli to protect cervical cells against gonococcal adherence was investigated.
