  1. 1. Cellulose nanofibril materials with controlled structure : the influence of colloidal interactions

    Author : Andreas Fall; Lars Wågberg; Anna Finne Wistrand; Paul Gatenholm; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Colloidal stability; cellulose nanofibrils; nanofibers; nanostructured materials; biocomposite; DLVO; gel;

    Abstract : Nanoparticles are very interesting components. Due to their very large specific surface area they possess properties in between molecules and macroscopic materials. In addition, a material built up of hierarchically assembled nanoparticles could obtain unique properties, not possessed by the nanoparticles themself. READ MORE

  2. 2. Colloidal interactions and orientation of nanocellulose particles

    Author : Andreas Fall; Lars Wågberg; Magnus Norgren; Markus Biesalski; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NFC; CNC; CNF; MFC nanocellulose; colloidal stability; orientation;

    Abstract : Nanoparticles are very interesting building blocks. Their large surface-to-bulk ratio gives them different properties from those of larger particles. Controlling their assembly can greatly affect macroscopic material properties. READ MORE

  3. 3. Colloidal interactions and arrested dynamics of cellulose nanofibrils

    Author : Malin Nordenström; Lars Wågberg; Torbjörn Pettersson; Lars Göran Ödberg; Andreas Fall; Wim Thielemans; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cellulose nanofibrils; colloidal interactions; colloidal stability; arrested state; colloidal glass; colloidal gel; tracer diffusion; counterion; steric stabilization; redispersion; redispersion agent; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Over the past decades, concerns for the environment have increased and efforts to achieve a sustainable society have intensified. One particular challenge is to replace fossil-based plastics with biodegradable materials produced from renewable resources. READ MORE

  4. 4. Acidaemia at Birth: Risk factors, diagnosis and prognosis, with special reference to maternal fever in labour

    Author : Andreas Herbst; Lund Obstetrik och gynekologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; andrology; gynaecology; Obstetrics; outcome; risk factors; perinatal asphyxia; acidosis; Acidaemia; reproduction; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet;

    Abstract : Acidaemia at birth is a result of an impaired intrauterine gas exchange. Between 1988 and 1996, acid-base balance in cord artery blood pH was assessed in 23 016 of 27 064 newborns (85%). Obstetric risk factors for acidaemia (cord artery pH < 7.05) were identified in a case-control study. READ MORE

  5. 5. Aerosol Measurements as Applied for Exposure Characterization

    Author : Andreas Dahl; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railroad; indoor air; environment; occupational health; exposure; isocyanate; airborne particles; station; traffic;

    Abstract : It is important to decrease the burden of disease. This is in part achieved by decreasing risks. The aim of this thesis is to provide a methodology for the characterization of aerosol exposure, which may lead to negative health effects. READ MORE
