  1. 1. Competing phases of matter: Experimental spectroscopy study of the transition metal dichalcogenides Fe-doped TaS2 and Cu-intercalated TiSe2

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Christian Stefan Gruber; [2023]
    Keywords : Condensed matter physics; transition metal dichalcogenides; photoemission spectroscopy;

    Abstract : Syftet med denna avhandling är att bidra till forskningen av befintliga TMD:er (på Engelska transition metal dichalcogenide-TMD) som visar laddningstäthetsvågor och supraledning vid låga temperaturer (som 2H-TaS2). 2H-TaS2 är också känt för att visa supraledning vid 2K. READ MORE

  3. 2. Optical Emission Spectroscopy Pulse Distribution Analysis on Steel Production Samples : Accuracy, sample variation, spread in different samples and steel grades/routes

    University essay from KTH/Materialvetenskap

    Author : Paulo Urrea Molina; [2023]
    Keywords : ;

    Abstract : This thesis work aimed to contribute to the development of online characterization techniques for non-metallic inclusions in steelmaking. The study focused on assessing the precision and accuracy of the optical emission spectroscopy pulse distribution analysis (OES/PDA) technique using asreference light optical microscope (LOM) and scanning electron microscope(SEM).

  4. 3. Optic Fiber Communication in Commercial Vehicles : Testing of mechanical rigidity

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Vijay Adhithyan Venugopal Parasuraman; [2022]
    Keywords : EMI; LASER; LED; MOST; EMC; CDMA; ECU; CAB; POF; LISN; SDK; EEPROM; USB;

    Abstract : The backbone of this dissertation is a discussion of the adaptability of optical fiber modes of transmission. The technological boom in commercial vehicles tends to include more electronic components and more data flow. The traditional copper transmission is reliable but has drawbacks. READ MORE

  5. 4. Measuring the Pulse Duration and the Time-Dependent Polarisation State of Ultrashort Laser Pulses with the D-Scan Technique

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

    Author : Daniel Díaz Rivas; [2022]
    Keywords : pulse characterisation; ultrashort; laser; femtosecond; dispersion scan; polarisation; wave plate; temporal reconstruction; electric field reconstruction; time-dependent polarisation; polarisation gate; Physics and Astronomy;

    Abstract : Ultrashort laser pulses with time-dependent polarisation states have many applications, such as the generation of isolated attosecond pulses and the study of the optical chirality of molecules. In this project the polarisation gate, built from two quarter-wave plates of different orders, is thoroughly characterised in experiment and simulation. READ MORE

  6. 5. Lubricants for Hot Stamping of Aluminum: Evaluation of Tribological Behavior and Cleanability

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Barbara Maria Rodriguez Leal; [2021]
    Keywords : Tribology; High-temperature; Metal-forming; Aluminum;

    Abstract : Working at elevated temperature has its challenges due to the high level of complexity whenthe tribosystems operate under harsh conditions, commonly resulting in an increase on thefriction and thermal softening that goes into severe adhesion, severe abrasion and materialtransfer. Despite considerable research, there is a lack of research on tribology applied to hightemperature processes. READ MORE
