  2. 1. Functional Polymer Electrolytes for Multidimensional All-Solid-State Lithium Batteries

    Author : Bing Sun; Daniel Brandell; Kristina Edström; Michel Armand; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer electrolyte; Li-battery; 3D-microbattery; Functionalization; Polyether; Polycarbonate; Copolymer; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : Pressing demands for high power and high energy densities in novel electrical energy storage units have caused reconsiderations regarding both the choice of battery chemistry and design. Practical concerns originating in the conventional use of flammable liquid electrolytes have renewed the interests of using solvent-free polymer electrolytes (SPEs) as solid ionic conductors for safer batteries.

  4. 2. In Vivo Accuracy and Precision in Prosthodontics

    Author : Robert Nedelcu; Andreas Thor; Ingela Nyström; Pontus Olsson; Per Vult von Steyern; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; accuracy; precision; in vivo; digital impression; intraoral scanner; polyether impression; implant impression; framework misfit; fully edentulous; Oral and Maxillofacial Surgery; Käkkirurgi; Oral and Maxillofacial Surgery; Käkkirurgi;

    Abstract : Background: There has been a dramatic increase in commercially available intraoral scanners (IOS) in the last decade, offering to replace indirect digitization of models (MOD) fabricated from impressions (IMPR). IOS has benefits of less patient discomfort and a faster workflow to fabricate fixed dental prosthesis (FDP), and implant-supported prostheses (IFD). READ MORE

  5. 3. On the Immune Regulation of Bone Response to Biomaterials

    Author : Ricardo Trindade; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomaterial; Immune System; Osseointegration; Foreign body reaction; Immune modulation; Titanium; Copper; Polyether ether ketone; PEEK;

    Abstract : Osseointegration is the biological basis for bone anchorage of oral implants, and revolu-tionized the replacement of lost teeth. It is also applied in bone anchored hearing aids and limb replacement in amputees. READ MORE

  6. 4. Polymer Ionic Materials: A Study of new Materials for Solid Polymer Fuel Cells and Rechargeable Polymer Batteries

    Author : Britta Mattsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PPO; polystyrene; neutron scattering; poly propylene oxide ; PEO; polymer electrolytes; poly vinylidene fluoride ; poly ethylene oxide ; luminescence; Raman spectroscopy; proton conducting polymer; poly styrene sulfonic acid ; PVDF;

    Abstract : Ion-containing polymeric materials are interesting for use in a wide variety of applications, where the flexible, yet mechanically stable, polymer matrix is essential. Intensive research is presently going on worldwide for applications as electrolytes in solid polymer batteries and fuel cells, where the ion-conducting polymer also serves as an electrode separator.

  7. 5. Antimicrobial Polymer Composites for Medical Applications

    Author : Peter Kaali; Sigbritt Karlsson; Ferruccio Doghieri; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; medical polymers; antimicrobial; body fluids; degradation; Polymer chemistry; Polymerkemi;

    Abstract : The current study and discuss the long-term properties of biomedical polymers in vitro and invivo and presents means to design and manufacture antimicrobial composites. Antimicrobialcomposites with reduced tendency for biofilm formation should lead to lower risk for medicaldevice associated infection. READ MORE
