  1. 1. An evaluation of materials and processes suitable for manufacturing micro HASEL-actuators

    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Anna Lindgren; [2021]
    Keywords : HASEL-actuator; paraffin blend;

    Abstract : HASEL-actuators use dielectric liquids and compliant shells as their media. This type of actuatorwould suit the actuators used as fins for soft milli robots (SOMIRO). These robots are going tobe used in aquaponic crops for studying its impact on the environment to help the farmersimprove their crops. READ MORE

  3. 2. Black phosphorous sample preparation for ultrafast electron diffraction studies

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

    Author : Rebecca Ahrling; [2020]
    Keywords : Graphene; Black phosphorus; electron diffraction; 2D material; Technology and Engineering;

    Abstract : Since 2004 when mechanical exfoliation was first utilised to produce single layered samples of graphite, 2D materials have gained interest in the scientific community. With the prerequisite that the initial bulk material has a layered structure, these 2D materials have created an opportunity to examine materials on a very small scale as well as opening the possibility of creating smaller electrical components for industrial and commercial use, with well-known and documented parameters.

  4. 3. Angular dependence of the Raman active phonon modes of Black Phosphorus

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

    Author : Armand Dominguez; [2019]
    Keywords : Black Phosphorus; Raman Spectroscopy; Physics and Astronomy;

    Abstract : This Master’s project presents on the angular dependence of the intensity of the Raman active phonon modes of Black Phosphorus (BP), a layered 2D material with unique and attractive characteristics to the scientific and engineering community. Raman spectroscopy is an indispensable tool in quick and unobtrusive analysis of chemical structures. READ MORE

  5. 4. Investigation of magnetic order in nickel-5d transition metal systems

    University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Author : Konstantinos Papadopoulos; [2019]
    Keywords : muSR; muons; skyrmions; magnetism; transition; spin; rotation; relaxation; resonance; thin; films; transition; metals; MBE; sputtering; XRR; reflectivity; molecular; beam; epitaxy; x; ray; TRIUMF; double; perovskite; longitudinal; transverse; nickel; Ni; asymmetry; positron; depolarization; chiral; lattice; helical; DM; interaction;

    Abstract : Double perovskite materials exhibit alterations in magnetic order through manipulation oftheir crystal structure. Certain ultra thin metallic bilayers can create an exotic magnetic stateof confined spin textures called skyrmions. In both cases, new atomic arrangements leadto new electrical and magnetic properties. READ MORE

  6. 5. Investigation of Methods to Detect Defects in Thin Layered Materials

    University essay from Blekinge Tekniska Högskola/Avdelningen för maskinteknik

    Author : Husam M. Hassan & Ajaykumar S. Chinthalapndi; [2005]
    Keywords : Thin layered materials; NDT; Vibration based; Air coupled ultrasonic; Acoustic microscopy; Ultrasonic spectroscopy; Shearography; and;

    Abstract : Cost effective and reliable damage detection is critical for the utilization of thin layered materials and microstructures. This Thesis presents a brief overview of conventional NDT methods and the usage of unconventional NDT methods applicable to thin layered materials, and the conclusion of applicability of these methods for damage detection in thin layered materials.
