1. 1. Exploratory study of additively manufactured heat exchangers for aerospace applications

   University essay from

   Author : Siddharth Nadukkandy; [2023]
   Keywords : ;

   Abstract : Thermal management is a crucial part in the aviation industry. It is also essential that the components involved in aviation be light weight. One of the vital components of thermal management is heat exchangers. It has been observed that the optimization of the heat exchanger is approaching its saturation with traditional manufacturing.

3. 2. Study of Triply Periodic Minimal Surfaces for Heat Transfer Applications

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : María Xuan Celaya Granados; [2023]
   Keywords : ;

   Abstract : In the pursuit of enhancing heat exchanger efficiency, several heat transfer- enhancing strategies are employed. The traditional methods include surface vibrations, microchannels, and integration of vortex generators. Additionally, new solutions are being studied, taking advantage of other relevant improve- ments in the engineering field. READ MORE

4. 3. Multi-Scale Topology Optimization of Lattice Structures Using Machine Learning

   University essay from Uppsala universitet/Tillämpad mekanik

   Author : Julia Ibstedt; [2023]
   Keywords : Topology optimization; Multi-scale topology optimization; Machine learning; Gaussian process; Homogenization; Inverse homogenization; Anisotropic materials; Symmetry groups; Material property space; Topologioptimering; Flerskalig topologioptimering; Maskininlärning; Gaussian process; Homogenisering; Anisotropa material; Symmetrigrupper; Materialegenskapsrymd;

   Abstract : This thesis explores using multi-scale topology optimization (TO) by utilizing inverse homogenization to automate the adjustment of each unit-cell's geometry and placement in a lattice structure within a pressure vessel (the design domain) to achieve desired structural properties. The aim is to find the optimal material distribution within the design domain as well as desired material properties at each discretized element and use machine learning (ML) to map microstructures with corresponding prescribed effective properties.

5. 4. 3D Printing of Magnesium- and Manganese-Based Metal-Organic Frameworks for Gas Separation Applications

   University essay from Uppsala universitet/Nanoteknologi och funktionella material

   Author : Dhruva Deole; [2022]
   Keywords : 3D Printing; Additive Manufacturing; Metal-Organic Frameworks; Carbon Capture; Gas Separation;

   Abstract : Metal Organic Frameworks (MOFs) are a class of porous materials that are predominantly obtained as powders and have been investigated as a solid sorbent for gas separation or carbon capture applications from combustion exhaust gases. The manufacturing of products with MOFs to use them for real life applications is still a major problem. READ MORE

6. 5. Electrochemical Behavior of the High Entropy Oxide (Mg,Co,Ni,Zn)1-xLixO (x=0,35)

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Rasmus Sandström Kinnane; [2022]
   Keywords : high entropy oxides; lithium-ion battery; x-ray diffraction; scanning electron microscopy; cyclic voltammetry;

   Abstract : Today's society is currently developing lithium-ion batteries to eventually replace the use of fossil fuels. High entropy oxides is a new type of material to use as an anode in the lithium-ion battery. These high entropy oxides may consist of a few different transition metals including lithium and oxygen.
