1. 11. Ammonium and nitrate sorption by biochar

   University essay from SLU/Dept. of Soil and Environment

   Author : Yasser Alrhban; [2023]
   Keywords : biochar nitrogen; retention; dialysis; absorption; adsorption; ammonium; nitrate;

   Abstract : Biochar has recently drawn attention due to its ability to increase soil fertility, sequester carbon and its expected effect on reducing the leaching of elements from the soil, especially nitrogen. The possibility of using biochar as a soil amendment to reduce the amount of nitrogen leaching, and then reducing the quantities of nitrogen fertilizers used in agriculture to avoid the bad environmental effects has become a matter of great interest.

3. 12. Adjoint optimization of a liquid-cooled heat sink

   University essay from KTH/Teknisk mekanik

   Author : Roven Pinto; [2023]
   Keywords : Adjoint method; topology optimization; porosity; OpenFOAM;

   Abstract : Improving the design of flow channels in a liquid-cooled heat sink is critical for boosting the capabilities of electronic components as well as reducing energy usage by the pump. This work explores the use of topology optimization to minimize the pressure difference across a heat sink and consequently, the energy used to supply the liquid. READ MORE

4. 13. Bluegreengrey (BGG) solution for future climate and flood-resilient urban drainage network by enhancing the natural hydrological cycle

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Adnan Asif Rifat; [2023]
   Keywords : Bluegreengrey; Sustainable stormwater; Basement flooding; Urban flooding; Pipe Network; BGG; Climate change; Hydrology; Mike .; Technology and Engineering;

   Abstract : A loop of urbanization, increasing impervious surface in urban areas, increasing temperature, rainfall, surface runoff and flooding, and lack of new spaces have been adding challenges to urban drainage systems for decades. The climate change impacts are exposing the existing vulnerable conventional urban drainage systems to more challenges in the future. READ MORE

5. 14. Investigation of high temperature stability of additive manufactured austenitic stainless steels for space applications

   University essay from Luleå tekniska universitet/Materialvetenskap

   Author : Belén Alonso Rancurel; [2023]
   Keywords : austenitic stainless steel; additive manufacturing; high temperature corrosion; high temperature stability;

   Abstract : Additive manufacturing (AM) techniques are being studied for their application in the aerospace industry. Numerous benefits come from the already in shape final piece, which needs reduced amount of prime material for its production and can have its shape numerically optimized for weight reduction.

6. 15. Study of Porosity in Uncoated Cemented Carbide Tools During Titanium Alloy Machining.

   University essay from Lunds universitet/Industriell Produktion

   Author : Cornelis Botermans; [2023]
   Keywords : Technology and Engineering;

   Abstract : During high speed machining of titanium alloys both the tool and workpiece material diffuse into one another affecting the surface integrity of the cutting tool edge and leading to fracture. One proposed mechanism by which the tool integrity is compromised results from the possible formation of porosity in to subsurface of the tool substrate close to the tool cutting edge. READ MORE
