2. 1. Aerosol Metal Nanoparticles and their Role in Particle-Assisted Growth of III–V Nanowires

   Author : Robert Hallberg; NanoLund: Centre for Nanoscience; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aerosol formation; III–V semiconductor materials; catalyst particles; Palladium nanoparticles; Gold nanoparticles; Spark discharge generation; MOVPE; MOCVD; Transmission electron microscopy TEM ; Phase stability; Nanoparticle deposition; Nanoparticle generation; nanoparticles characterization; Nanowire NW ; Nanowire growth;

   Abstract : Semiconductor nanowires have properties that make them potentially useful for applications in future electronic, photovoltaic, and optoelectronic devices. A powerful nanowire fabrication technique is the use of a nanoparticle as a preferential nucleation site, from which a nanowire grows. READ MORE

4. 2. Nano- and Micro-sized Molecularly Imprinted Polymer Particles on Solid Surfaces

   Author : Tripta Kamra; Synkrotronljusfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Molecularly imprinted polymers (MIPs) are artificial receptors made by imprinting template molecules in a polymer matrix followed by their removal through washing to obtain a specific and selective template cavities. This property of the MIPs have made them a very efficient material for diverse applications such as chromatography, purification, drug sensing, etc. READ MORE

   Abstract : Solid oxide fuel cells (SOFCs) are considered as one of the most promising power generation technologies due to their high energy conversion efficiency, fuel flexibility and reduced pollution. There is a broad interest in reducing the operating temperature of SOFCs. READ MORE

6. 4. Chip-based magnetic levitation of superconducting microparticles

   Author : Martí Gutierrez Latorre; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Magnetically levitated superconductors are extremely isolated from the environment, their mechanical properties can be tuned magnetically, and can be coupled to quantum systems such as superconducting quantum circuits. As such, they are a promising experimental platform for the creation of massive spatial quantum states that would test quantum mechanics in a hitherto unexplored parameter regime. READ MORE

7. 5. Characterization of Multifunctional Nanomaterials for Electronics Thermal Management and Sintering Applications

   Author : Abdelhafid Zehri; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The science of manipulating materials at their nanoscale level is nowadays allowing endless possibilities to disrupt the current limitations on the conventional production processes and products. In electronics, the need for more capable thermal management strategies led to the exploration of advanced approaches and focus on new materials and allowed to push further the thermal dissipation capabilities of each generation of products.
