  1. 1. Structural analysis of HZO thin film and electrode using X-ray diffraction

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Elliot Winsnes; [2024]
    Keywords : HZO; hafnia; hafnium dioxide; zirconium dioxide; ferroelectricity; ferroelectric; synchrotron radiation; X-ray diffraction; Physics and Astronomy;

    Abstract : Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. READ MORE

  3. 2. Developing a Test Method to Evaluate the Blackout Effect of Uncoated Curtains at Varying Angles

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Sara Muminovic; Christina Lindén; [2023]
    Keywords : Blackout effect; blackout curtain; uncoated woven curtains; angle interval; light transmission; light box; light diffuser; microscopic image analysis;

    Abstract : This study aimed to explore the integration of varying angles in small-scale measurements and assess the light transmission performance of uncoated curtains. A total of four curtains were evaluated: blackout curtain samples 1 and 2 had a weft satin structure, while daytime curtain samples 3 and 4 consisted of a twill structure. READ MORE

  4. 3. Control Aid Implementation -Modelling and simulation of triple extruder-

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Karl Langsér; [2023]
    Keywords : Machine Learning; Extruder; Modelling; Simulation; Extreme learning machine; Chemical engineering; Technology and Engineering;

    Abstract : In the production of their High Voltage Direct Current Cables (HVDC) and High Voltage Alternating Current Cables (HVAC), NKT uses triple extruders to create layers of insulation and semi-conduction. A model to predict the effect of extruder inputs on the cable’s insulation and semi-conducting layers has been created and trained to predict the extruder in discrete time. READ MORE

  5. 4. The Development and Testing of Low-Cost Heat Transfer Enhancements for Solar Dryers

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Hoda Mahmoodi; [2023]
    Keywords : Solar dryer; Bhutan; Drying rate; Solar absorber; Technology and Engineering;

    Abstract : In the mountainous regions of Bhutan and Nepal, post-harvest losses cause significant challenges for producers. Open air sun drying is usually used by farmers to preserve their produce. There are many disadvantages to this method. READ MORE

  6. 5. Impact of Organic Solvent Treatments on Physical and Sensorial Properties of Knitted Fabrics.

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Sara Isabel Zamora Lagos; [2023]
    Keywords : Innovation; Screen-printing; Knitted fabric; Polyester; Cotton; Organic Solvents; Cycle; Properties; Physical; Structure; Sensorial.;

    Abstract : Technologies that facilitate reusing and recycling printed textile products will contribute to achieving a circular textile industry. This project was done in collaboration with Vividye, a company developing a technology to create removable textile prints to be able to extend the lifespan of screen-printed textile products without affecting their quality.
