  1. 21. Cross-linking and surface properties of EHEC and Starch -a QCM-D study

    Författare :Jesper Hedin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrogel; GMA; HM-EHEC; Starch; vicoelastic properties; Imidazole; QCM-D; SPR; EHEC;

    Sammanfattning : The increase of the green house gases and the crude oil price has resulted in a willingness to change the raw material in many industries from petroleum-based polymers to natural polymers. One such natural polymer is starch. Today, starch is used in the glue industry in wallpaper pastes. LÄS MER

  3. 22. Investigation of electrochemical properties and performance of stimulation/sensing electrodes for pacemaker applications

    Författare :Anna Norlin; Jinshan Pan; Dieter Scharnweber; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; pacemaker electrode; interfacial property; biomaterial; electrostimulation charge transfer mechanism; electrochemical impedance spectroscopy; transient processes; plasma electrolysis anodisation; porous niobium oxide; ruthenium oxide; nano-porous carbon; iridium oxide; titanium nitride; platinum; surface roughness; porous electrode; pacing impedance; electrode polarisation; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : People suffering from certain types of arrhythmia may benefit from the implantation of a cardiac pacemaker. Pacemakers artificially stimulate the heart by applying short electrical pulses to the cardiac tissue to restore and maintain a steady heart rhythm. By adjusting the pulse delivery rate the heart is stimulated to beat at desired pace. LÄS MER

  4. 23. Fundamentals of Interactions between Cellulose Materials and its Implications on Properties of Fibrous Networks

    Författare :Nadia Asta; Lars Wågberg; Scott Renneckar; KTH; []

    Sammanfattning : Fundamental research plays a pivotal role in the development of sustainable solutions that benefit both our environment and everyday lives. Cellulose, as an abundant and renewable resource, holds immense potential for sustainable applications. LÄS MER

  5. 24. Interphases in Polymer Blends

    Författare :Hans Eklind; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; morphology; interdiffusion; compatibilization; characterization; interfacial interaction; mobility; micromechanical transition; dynamic mechanical properties; interphase; polymer blend;

    Sammanfattning : The blending of polymers is a useful means of combining and improving the properties of already existing polymers in the development of new materials at reasonable cost. As most polymers are immiscible with each other, heterogeneous blends are often formed. The properties of such blends are strongly determined by the properties of the interphase. LÄS MER

  7. 25. Modelling electrical properties of composite materials

    Författare :Eva Mårtensson; KTH; []
    Nyckelord :;

    Sammanfattning : Composite field grading materials are used to avoid stressconcentrations in high voltage applications such as cableaccessories and generator or motor end windings. The compositematerials consist of an insulating matrix filled with suitableconducting or semi-conducting particles. Silicon carbide (SiC)powder is one such filler that is being employed. LÄS MER
