2. 1. Manufacturing and characterization of nanomaterials for low-temperature sintering and electronics thermal management applications

   Author : Abdelhafid Zehri; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-elements alloyed nanoparticles; sintering aid; PCM; phase change materials; graphene coating; heat spreader; graphene foam; nanofluids;

   Abstract : Nanotechnology is expected to have a significant impact on the long-term development within and across many disciplines. While offering potential improvements in energy efficiency and reduced energy and materials consumption, nanomaterials are at the centre of the cutting-edge technologies and sustainable manufacturing processes era with near half of the products in the next period of 10 years expected to embed nanoscale solutions.

4. 2. Experimental and Mathematical Study of Incompressible Fluid Flow through Ceramic Foam Filters

   Author : Shahin Akbarnejad; Ragnhild Elizabeth Aune; Pӓr Jönsson; Andreas Westermoen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Ceramic Foam Filters (CFFs) are widely used to filter solid particles and inclusions from molten metal in metal production, particularly in the aluminum industry. In general, the molten metal is poured on the top of a ceramic foam filter until it reaches a certain height, also known as metal head or gravity head. READ MORE

   Abstract : The objective of this doctoral thesis is to study three different innovative noise control techniques in ducts namely: acoustic metamaterials, porous absorbers and microperforates. There has been a lot of research done on all these three topics in the context of duct acoustics. READ MORE

7. 5. Avoiding slopping in top-blown BOS vessels

   Author : Mats Brämming; Göran Carlsson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

   Abstract : Slag formation plays a decisive role in all steelmaking processes. In top-blowing Basic Oxygen Steelmaking (BOS), i.e. in the LD process, an emulsion consisting of liquid slag, dispersed metal droplets and solid particles will, together with process gases, form an expanding foam.
