2. 1. Nanoparticles : Engineering, Assembly, and Biomedical Applications

   Author : Do Kyung Kim; KTH; []
   Keywords : nanoparticle; superparamagnetism; self assembly; ;

   Abstract : This thesis deals with novel aspects through Nanotechnologyof"bottom-up"and"top-down"strategies in combination with Biotechnology as aninterdisciplinary study. The feasibility of chemically tailoredsuperparamagnetic iron oxide nanoparticles (SPION) forin-vivobiomedical applications has beendemonstrated. READ MORE

4. 2. Multicomponent Clusters/Nanoparticles : An Investigation of Electronic and Geometric Properties by Photoelectron Spectroscopy

   Author : Chaofan Zhang; Olle Björneholm; Maxim Tchaplyguine; Svante Svensson; Gerd Ganteför; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Clusters; Nanoparticles; Alloy; Atmospheric chemistry; Alkali halide; Transition metals; X-ray Photoelectron spectroscopy; Polarizability; Core-shell; Sandwich structure; MAX-lab; BESSY II;

   Abstract : Clusters/nanoparticles are aggregates of a “small” number of building blocks, atoms or molecules, ranging from two up to millions of atoms. Two main groups of clusters have been studied using photoelectron spectroscopy based on synchrotron radiation. READ MORE

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

   Author : Narges Bayat; Susana Cristobal; Janeck James Scott-Fordsmand; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanoparticles; Nanotoxicology; Ultra-small nanoparticles; Biochemistry; biokemi;

   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

6. 4. Aerosol Synthesis and Characterization of Heterogeneous Bimetallic Nanoparticles

   Author : Markus Snellman; NanoLund: Centre for Nanoscience; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; core-shell; Janus nanoparticles; aerosol technology; Fysicumarkivet A:2023 Snellman; Nanopartiklar; kärna-skal; Januspartiklar; aerosolteknologi;

   Abstract : As the proverbial noose tightens around humanity’s resource spending, research is focused on utilizing materials to their fullest potential. Nanotechnology is the ultimate way to economize by splitting objects into smaller parts and dispersing the material properties over greater surface to volume ratios. READ MORE
