  1. 6. Crystallinity of Sputtered TiO2 Thin Films: a Study of the Heating and Plasma Influence on the Growth

    University essay from

    Author : oussama ezzaher; [2023]
    Keywords : ;

    Abstract : AbstractHigh-Power Impulse Magnetron Sputtering (HIPIMS) of TiO2 thin films enhances their photocatalyticproperties compared to the films prepared by standard sputtering methods, especially when no substrateheating is employed. With no heating, the coatings present an amorphous structure that benefits from theionization of the sputtered flux granted by HiPIMS, with respect to their photocatalytic performance. READ MORE

  3. 7. Developing an ML-based model for RF tuning of the DTL machine at ESS

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Amin Hosseini Nejad; [2023]
    Keywords : Technology and Engineering;

    Abstract : The European Spallation Source (ESS) infrastructure is being constructed in Lund, and will be one of the most powerful research facilities of its type in the world. The ESS linear accelerator (linac) utilizes different accelerating sections where a wide variety of techniques should be employed to accelerate a beam of protons to 2 GeV kinetic energy through Radio Frequency (RF) cavities before being collided with a tungsten target for the final production of neutrons, through the process of spallation.

  4. 8. Design and implementation of an energy harvesting system in a prosthetic limb

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ódinn K. Rúnarsson; [2023]
    Keywords : Energy harvesting; Prosthetic limbs; Supercapacitors; Printed circuit boards; 3D printing; Energiinsamling; Lemmproteser; Superkondensatorer; Tryckta kretskort; 3D Utskrivning; Orkuöflun; Gervilimir; Ofurþéttar; Prentaðar rafrásir; Þrívíddarprentun;

    Abstract : Energy Harvesting, also known as power harvesting or ambient power, is the process of obtaining small amounts of power from secondary sources, such as vibrations, light, temperature variations and even radio-frequency emissions. These systems have been uncommon in personal and wearable electronics in the past, however they are slowly gaining traction. READ MORE

  5. 9. Frequency Stabilization in low Inertia Systems With Battery Power Injections

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Leif Lundin; [2023]
    Keywords : ;

    Abstract : The challenges for the power system of the future becomes increasingly larger when large amountsof renewable energy sources are integrated, and when conventional forms of power such asnuclear power are phased out. This results in a greater difficulty in quickly deploying FrequencyContainment Reserves in the event of of power balance disturbance, to stabilize frequency andvoltage. READ MORE

  6. 10. Production and analysis of novel disulfide variants of Subtilisin Carlsberg

    University essay from Linköpings universitet/Kemi

    Author : Anton Elfstrand; [2023]
    Keywords : Subtilisin Carlsberg; Disulfide; Protein Engineering; Kinetic Stability;

    Abstract : Protein engineering has been used to alter the stability of proteins for several decades withmuch success, one approach being to introduce two cysteine residues that together form adisulfide bridge. The disulfide bridge can increase the Gibbs free energy of the transitionstate, thus increasing energy difference between the folded state and the unfolding transitionstate, leading to increased kinetic stability of the protein.
