    Abstract : Today, the growing and aging population, and the rise of new global threats on human health puts an increasing demand on the healthcare system and calls for preventive actions. To make existing medical treatments more efficient and widely accessible and to prevent the emergence of new threats such as drug-resistant bacteria, improved diagnostic technologies are needed.

  2. 2. Structure-Property Relationships of Surfactants at Interfaces and Polyelectrolyte-Surfactant Aggregates

    Author : Mikael Kjellin; KTH; []
    Keywords : nonionic surfactant; sugar surfactant; poly ethylene oxide ; amide; ester; polyelectrolyte; SDS; hydrophobic surface; glass surface; mica; adsorption; aggregation; micelle size; surface forces; wetting; dynamic surface tension; NMR; TRFQ; SANS; SAXS; ;

    Abstract : The first part of this thesis is concerned with thestructure-property relationships in nonionic surfactantsystems. The main aim was to investigate how the surfactantstructure influences the adsorption at interfaces andinteractions between surfactant coated interfaces. READ MORE

  3. 3. Dispersion Engineering : Negative Refraction and Designed Surface Plasmons in Periodic Structures

    Author : Zhichao Ruan; Min Qiu; Henri Benisty; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photonic crystal; dispersion property; negative refraction; surface plasmon polariton; designed surface plasmon; negative index material; layer-KKR method; finite-difference time-domain method; plane wave method; subwavelength imaging; open cavity; enhanced transmission; slowing light; Photonics; Fotonik;

    Abstract : The dispersion property of periodic structures is a hot research topic in the last decade. By exploiting dispersion properties, one can manipulate the propagation of electromagnetic waves, and produce effects that do not exist in conventional materials. READ MORE

  4. 4. Surface reactivity of metal nanoparticles : - importance of surface active agents and biomolecules from a transformation, mobility and toxicity perspective

    Author : Sara Skoglund; Inger Odnevall Wallinder; Lars Österlund; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; metal nanoparticles; surfactants; metal release; characterization; size distribution; nanotoxicology; risk assessment; Kemi; Chemistry;

    Abstract : Metallic nanoparticles possess unique properties due to their size and are widely used in e.g. consumer products. From this follows a need to identify and assess potential risks of human and environmental exposure. READ MORE

  5. 5. Thermoset polymers and coatings subjected to high compressive loads

    Author : Daniel Ståhlberg; Mats Johansson; Gijsbertus de With; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymers; organic coating; thermoset; mechanical properties; compression; Surface engineering; Ytbehandlingsteknik;

    Abstract : This study describes the mechanical response of thermoset polymers under high compressive loads. The study is divided into two parts. The first part focuses on the behaviour of a powder coating when used in a clamping force joint and how the properties vary when the chemical and physical structure of the coating is changed.
