  2. 16. Multifunctional nanomaterials for diagnostic and therapeutic applications

    Author : Andrea Fornara; Mamoun Muhammed; Patrick Saulnier; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi;

    Abstract : In the past few years, the use of nanostructured materials in medical applications hasdramatically increased, both in the research phase and for clinical purposes, due to thepeculiar properties and the ability of such materials to interact at a similar scale withbiological entities. In this thesis, we developed tailored magnetic multifunctionalnanoparticles for diagnostic and therapeutic applications, such as detection ofbiomolecules, simultaneous enhanced magnetic resonance imaging (MRI), fluorescentvisualization and controlled drug release.

  4. 17. Engineering Nanofluids for Heat Transfer Applications

    Author : Nader Nikkam; Toprak Muhammet; Mamoun Muhammed; Yulong Ding; KTH; []
    Keywords : nanofluid; thermal conductivity; viscosity; heat transfer; heat transfer coefficient; HTC; SiC nanoparticles; Cu nanoparticles; mesoporous silica; CNT; microwave synthesis; Kemi; Chemistry;

    Abstract : Nanofluids (NFs) are nanotechnology-based colloidal dispersion prepared by dispersing nanoparticles (NPs) in conventional liquids, as the base liquid. These advanced fluids have displayed potential to enhance the performance of conventional heat transfer fluids. READ MORE

  5. 18. Environment-Sensitive Multifunctional Drug Delivery Systems

    Author : Jian Qin; Mamoun Muhammed; Marcus Textor; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Materials chemistry; Materialkemi;

    Abstract : Drug delivery systems (DDS) with multiple functionalities such as environment-sensitive drug release mechanisms and visualization agents have motivated the biomedical community as well as materials chemists for more than a decade. This dissertation is concerned with the development of nanoparticles for multifunctional DDS  to tackle several crucial challenges in these complex systems, including polymeric nanospheres which respond to temperature change, superparamagnetic iron oxide nanoparticles/polymeric composite for magnetic resonance imaging contrast agents and drug carriers, immunoresponse of nanomaterials and injectable magnetic field sensitive ferrogels.

  6. 19. Nano-EngineeredThermoelectric Materials for Waste Heat Recovery

    Author : Mohsin Saleemi; Muhammet Toprak; Mari-Ann Einarsrud; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Energy crisis and thermal management related issues have been highlighted in the modern century due to escalating demands for energy consumption and global warming from fossil fuels. Sustainable and alternative energy sources are an ever growing global concern. READ MORE

  7. 20. Fabrication and Photoelectrochemical Applications of II-VI Semiconductor Nanomaterials

    Author : Abhilash Sugunan; Muhammet Toprak; Mamoun Muhammed; Gerrit Boschloo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ZnO; nanowire arrays; photocatalysis; CdTe; CdSe; CdS; nanotetrapods; nanotetrahedrons; photoconduction; nano-gap electrodes; Type-II QDs; P3HT nanofibers; microwave synthesis.;

    Abstract : In this work we investigated fabrication of semiconductor nanomaterials and evaluated their potential for photo-chemical and photovoltaic applications. We investigated different II-VI semiconductor nanomaterial systems; (i) ZnO oriented nanowire arrays non-epitaxially grown from a substrate; and (ii) colloidal CdE (E=Te,Se,S) quantum structures synthesized by solution-based thermal decomposition of organo-metallic precursors.
