  1. 21. Application of magnetic nanoparticles and reactive filter materials for wastewater treatment

    Author : Ramnath Lakshmanan; Gunaratna Kuttuva Rajarao; Erik Dahlquist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reactive filter materials; magnetic nanoparticles; wastewater treatment process; nutrient reduction; sludge water content; toxicity of magnetic nanoparticles;

    Abstract : Lately sewage wastewater treatment processes (WWTP) are facing challenges due to strict regulations in quality of effluent standards and waste production. The reuse of wastewater treatment effluents is rapidly gaining attention as a means of achieving sustainable water supply. Therefore, new methods are required to achieve an efficient WWTP. READ MORE

  2. 22. Development of Protein-Functionalized Magnetic Iron Oxide Nanoparticles: Potential Application in Water Treatment

    Author : Chuka Okoli; Gunaratna Kuttuva Rajarao; M. Arturo López-Quintela; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The treatment of water to make it safe for human consumption is a problem of immense concern, both in developing and developed countries. However, the production of clean water with chemicals as coagulants has several drawbacks associated with cost, health risks and complexity in sludge management. READ MORE

  3. 23. Spectroscopic studies of biomolecules confined in self-assembled nanostructures

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The present thesis examines the effects of incorporating biomolecules into self-assembled nanostructures. This approach is exemplified by short DNA molecules in environments close to lipid bilayers and the immobilization of enzymes into mesoporous silica particles. READ MORE

  4. 24. Plasmonics with a Twist: from Single Particles to Metasurfaces

    Author : Robin Ogier; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; colloidal lithography; localized surface plasmons; circularly polarized light; metsurfaces; nanofabrication; chirality; optical trapping;

    Abstract : Nanophotonics deals with how electromagnetic fields can be confined and squeezed to orders of dimensions below the light wavelength. Plasmonics, one of the fields of nanophotonics, study collective free electron oscillations driven by light in metallic nanostructures and interfaces. READ MORE

  5. 25. Development of high-Tc SQUID magnetometers for on-scalp MEG

    Author : Minshu Xie; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanowire junctions; on-scalp MEG; Bicrystal grain boundary; magnetoencephalography; YBCO; magnetometers; high-Tc SQUIDs;

    Abstract : This thesis describes the development of high critical temperature superconducting quantum interference device (high-Tc SQUID) magnetometers based on bicrystal grain boundary and nanowire junctions for the potential use in on-scalp magnetoencephalography (MEG), which is a new generation MEG technique with reduced sensor-to-subject standoff distances.MEG is a method of mapping neural dynamics in the human brain by recording the magnetic fields produced by neural currents.
