  1. 1. Engineered nanomaterials in in vivo and in vitro models

    Författare :Laura Abariute; NanoLund: Centre for Nanoscience; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; III-V semiconductor nanowires; Nanoparticle exposure; Mouse exposure; Cell exposure; Nanotoxicology; Nanosafety; Fysicumarkivet A:2018:Abariute;

    Sammanfattning : Nanotechnology and engineered nanomaterials (ENM) empower existing technologies. One of the great examples are III-V semiconductor nanowires (NW), which have a broad application range. The occupational safety and hazard organizations draw attention to ENM, as their physical and chemical characteristics differ from the ones of bulk materials. LÄS MER

  3. 2. Too Enabling to Fail – Ethics and Practices in the Legitimation of Nanotechnology

    Författare :Nicholas Surber; Chalmers tekniska högskola; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; enabling technology; responsible research and innovation; legitimation crisis; applied ethics; risk sociology; political economy of research and innovation; research and innovation policy; nanotechnology; technoscientific capitalism; emerging technology;

    Sammanfattning : This thesis reads Beck’s Risk Society in the context of nanotechnology and the politicization of failure in the promise of enabling technologies. It aims to investigate how researchers and innovators legitimate nanotechnology in society. LÄS MER

  4. 3. Surface reactivity, stability, and mobility of metal nanoparticles in aqueous solutions : Influence of natural organic matter and implications on particle dispersion preparation

    Författare :Sulena Pradhan; Inger Odnevall Wallinder; Jonas Hedberg; Eva Blomberg; Emma Strömberg; Kerstin Forsberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanoparticles; freshwater; di-hydroxybenzoic acid; humic acid; copper; aluminium; manganese; dissolution; agglomeration; stability; complexation; Kemi; Chemistry;

    Sammanfattning : The growing development of nanotechnology has resulted in an increased use of nanoparticles (NPs) in various applications ranging from medicine, military, to daily consumer products. There is a concern that NPs can be dispersed into the environment in various ways, for example to air and water during manufacture, use, incineration or recycling of products and thus pose a risk to health and the environment.
