  1. 1. 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

  4. 3. Silicone obturators and the bacterial flora in symptomatic nasal septal perforations

    Författare :Anna Karin Hulterström; Anders Berglund; Diana Berggren; Åke Davidsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nasal mucosa; perforation; symptomatic; inflammation; Staphylococcus aureus; obturator treatment; medical silicone; wettability;

    Sammanfattning : Background A perforation in the nasal septum can cause symptoms such as bleeding, obstruction, crusts and pain, and can be a challenge to treat. Surgery is the treatment of choice, but disease, size of the perforation, or the patient’s wish may contradict surgery. LÄS MER

  5. 4. Materials and Devices for Stretchable Electronic Nerve Interfaces

    Författare :Samuel Lukas Lienemann; Klas Tybrandt; Magnus Berggren; Diego Ghezzi; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stretchable electronics; Nanowires; Peripheral nerve interfaces; Cuff electrodes;

    Sammanfattning : Within our body, there is a large network of nerves that facilitates communication between the brain and the body’s organs. This network is called our peripheral nervous system, consisting of soft and stretchable nerve bundles that gradually increase in their functional specificity as they split and branch out the closer they get to their target organ.

  7. 5. The missing links : Towards an Informed Substitution of Durable Water Repellent Chemicals for Textiles

    Författare :Steffen Schellenberger; Ian Cousins; Stefan Stolte; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Durable water repellents (DWRs) that provide liquid repellency to functional textiles are part of an ongoing global substitution process. The process of substitution was initiated after DWRs based on side-chain fluorinated polymers (long-chain SFPs) were identified to contribute to the diffuse release of long-chain perfluoroalkyl acids (PFAAs) to the environment.
