1. Toxicity and biological impact of metal and metal oxide nanoparticles Focus on the vascular toxicity of ultra-small titanium dioxide nanoparticles

University dissertation from Stockholm. Department of Biochemistry and Biophysics, Stockholm University

Abstract. The application of nanoparticles (NPs) in different technologies has led to tremendous advancement in those fields. Moreover, there is growing interest in application of ultra-small NPs (USNPs) at 1-3 nm due to their distinct molecule like features. Parallel to these promises, there is a growing concern regarding their safety. READ MORE

2. Metal Particles – Hazard or Risk? Elaboration and Implementation of a Research Strategy from a Surface and Corrosion Perspective

University dissertation from Stockholm. KTH

Abstract. Do metal particles (including particles of pure metals, alloys, metal oxides and compounds) pose a hazard or risk to human health? In the light of this question, this thesis summarizes results from research conducted on metal particles, and describes the elaboration and implementation of an in vitro test methodology to study metal release from particles through corrosion and dissolution processes in synthetic biological media relevant for human exposure through inhalation/ingestion and dermal contact.Bioaccessible metals are defined as the pool of released metals from particles that potentially could be made available for absorption by humans or other organisms.

3. Metal Films for Printed Electronics Ink-substrate Interactions and Sintering

University dissertation from Sundsvall.

Mid Sweden University

Abstract. A new manufacturing paradigm may lower the cost and environmental impact of existing products, as well as enable completely new products. Large scale, roll-to-roll manufacturing of flexible electronics and other functionality has great potential. READ MORE

4. Thermal and Photon Stimulated Reactions on Metal Particles

University dissertation from Chalmers University of Technology

Abstract. The interaction between molecules and solid surfaces influence our daily lives in many ways. One important example is heterogeneous catalysis where surface reactions, for example, are used for production of chemicals and exhaust after-treatment. READ MORE

5. Colloidal synthesis of metal oxide nanocrystals and thin films

University dissertation from Institutionen för fysik, kemi och biologi

Abstract. A main driving force behind the recent years’ immense interest in nanoscience and nanotechnology is the possibility of achieving new material properties and functionalities within, e.g. material physics, biomedicine, sensor technology, chemical catalysis, energy storing systems, and so on.
