  1. 21. Structure formation at solid/liquid interfaces : Understanding self-assembly and environmental challenges

    Författare :Shirin Nouhi; Adrian R. Rennie; Vassilios Kapaklis; Maja S. Hellsing; Ann Terry; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solid liquid interface; neutron scattering; colloidal particles; self-assembly; perfluoroalkyl substance; Moringa seed proteins; adsorption; lamellar disorder; thermal fluctuations.;

    Sammanfattning : The work described in the present dissertation has explored the structure of particles and molecules at solid/liquid interfaces, aiming to understand the physics of self-organizing systems and use this knowledge to address some environmental issues. Surface-sensitive neutron scattering techniques, such as reflectometry and grazing incidence small angle scattering, have been used as the primary tool to investigate structures in proximity to an interface.

  3. 22. Fewer kids not always by choice : the link between endocrine-disrupting chemicals and female reproductive health

    Författare :Richelle Duque Björvang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Fertility rates are declining from five children per woman in the 1950s to less than three children per woman in 2019. While this is partly due to women choosing to have fewer kids, there are growing evidence that endocrine-disrupting chemicals (EDCs) in the environment may play a role in this phenomenon. LÄS MER

  4. 23. Environmental Assessment of Alternative Durable Water Repellent Chemicals. First steps towards a holistic assessment

    Författare :Hanna Holmquist; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LCA; diffuse emissions; wax; silicones; risk assessment; DWR; PFAS; CAA; dendrimers;

    Sammanfattning : Durable water repellent (DWR) finishes are applied to textiles to impart water and in some cases oil repellency. Water (and oil) repellency can be an important contribution to a textile’s performance, for comfort or for the protection of human lives under extreme conditions. LÄS MER

  5. 24. Early life environmental exposures and children's growth : A longitudinal study evaluating prenatal exposure for endocrine disrupting chemicals and nutrition in relation to children's growth up to seven years of age

    Författare :Katherine Svensson; Carl-Gustaf Bornehag; Sverre Wikström; Chris Gennings; Alicja Wolk; Marie Löf; Karlstads universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endocrine disrupting chemicals; EDC; Nutrition; Pregnancy; Children; Growth; Birthweight; Body composition; Body Fat; BMI; Overweight; Public Health Science; Folkhälsovetenskap;

    Sammanfattning : Endocrine disrupting chemicals (EDCs) have the potential to disrupt the endocrine system in humans and animals with importance for health and development. Additionally, optimal nutrition during pregnancy is critical for fetal growth and pregnancy outcomes. LÄS MER

  7. 25. Occurrence and removal of organic micropollutants in drinking water : Analytical approaches for wide-scope screening of contaminants of emerging concern

    Författare :Rikard Tröger; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : With the rapidly expanding global population, demand for clean drinking water is increasing. However, the widespread use of synthetic chemicals makes it challenging to produce safe and clean drinking water. LÄS MER
