4. 2. Coated Norway Spruce : Influence of Wood Characteristics on Water Sorption and Coating Durability

   Author : Tinh Sjökvist; Åsa Blom; Carsten Mai; Linnéuniversitetet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Heartwood; Sapwood; Wood extractives; Moisture content; Paint; Alkyd; Acrylic; Linseed oil; Calcimine paint; Mould; Fungi; Algae; Weathering; Forestry and Wood Technology; Skog och träteknik;

   Abstract : Wood used outdoors is often degraded and discoloured by microorganisms as a natural part of its life cycle, particularly when exposed to high levels of moisture for prolonged times. In this case, the application of a coating (i.e. paint) is an option for increasing the service life of the wood. READ MORE

5. 3. Non-ionic contrast media in acrylic bone cement

   Author : Fred Kjellson; Lund Ortopedi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; Kirurgi; ortopedi; traumatologi; Material technology; Materiallära; materialteknik; PMMA; Bone cement; particle size; contrast media; radiopacity; iohexol; iodixanol; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; orthopaedics; Surgery; medicinsk instrumentering;

   Abstract : Non-ionic, water-soluble, contrast media, iohexol and/or iodixanol, have been investigated for use in acrylic bone cement aimed for arthroplasty. Bone cement, containing the new particulate contrast media , was investigated for: quasi-static mechanical properties, water uptake properties, release of contrast media from the bone cement, biological responses from particulate bone cement, polymerisation reaction, polymerisation temperature, glass transition temperature, injectability and penetration into human cancellous bone, and radiopacity.

6. 4. Exploring strategies to improve volumetric hydrogen productivities of Caldicellulosiruptor species

   Author : Thitiwut Vongkampang; Teknisk mikrobiologi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Caldicellulosiruptor kronotskyensis; volumetric hydrogen productivity; non-diauxic; acrylic fibres; cell immobilization; chitosan; biofilm; c-di-GMP; cellobiose; xylose; consolidated bioprocessing; heat-treated wheat straw;

   Abstract : Ongoing consumption of fossil-based fuels generates a massive amount of greenhouse gases. This may lead to global warming that is currently threatening human society and wild animal habitats. Hydrogen is an energy carrier with the highest energy content per weight compared to other all fuels and no carbon dioxide is released when combusted. READ MORE

7. 5. Steric Stabilization of Polylactide particles achieved by Covalent 'grafting-from' with Hydrophilic Polymers

   Author : Robertus Wahyu Nayan Nugroho; Ann-Christine Albertsson; Karin Odelius; Anders Höglund; Mark Rutland; Martina Janstål; KTH; []
   Keywords : Steric stabilization; AFM; hydrophilicity; surface modification; poly lactide ; acrylamide; acrylic acid; maleic anhydride;

   Abstract : Despite numerous advantages of using particles in a wide range of applications, they have one drawback that is their tendency to agglomerate. One way to overcome this problem is to sterically  stabilize the particles by introducing polymeric  chains covalently attached to the surface. READ MORE
