    Sammanfattning : This thesis presents my mostly unpublished experimental work related to two major contributions with the design of: A high precision and versatile bulk average(or integral) AC-susceptometer and its application to investigations of exchange anisotropy in Co multilayers. A novel Local Susceptibility measurement technique exploiting the narrow gap in inductive ring-heads in magnetic recording technology. LÄS MER

  3. 3. Transport properties of Bi2Se3 Topological Insulator Nanoribbon-Superconductor hybrid junctions

    Författare :Ananthu Pullukattuthara Surendran; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bismuth selenide; surface states; Topological insulator; ac susceptibility; Josephson junctions; superconductivity; SQUID; andreev bound states;

    Sammanfattning : In recent years, topological superconductivity and Majorana zero-energy modes have attracted vast interest due to their potential for topologically protected quantum information processing. Hybrid devices involving a conventional s-wave superconductor (S) in proximity to a 3D Topological Insulator (TI) are expected to provide a platform for emulating and studying these phenomena.

  4. 4. Genetic susceptibility to breast and endometrial cancer

    Författare :Sara Wedrén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Hormones are central in the carcinogenic process in the breast and in the uterine epithelium. Individual genetically determined variation in the response to hormonal influence may alter susceptibility to breast and endometrial cancers. Many small studies of this hypothesis have generated inconclusive results. LÄS MER

  5. 5. Differential Magnetic Biosensor using HTS SQUID Gradiometer

    Författare :Sobhan Sepehri; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-Tc SQUID; magnetic bioassay; diagnostics; RCA; microfluidics; magnetic nanoparticle; point-of-care; rolling circle amplification; differential ac susceptibility; biosensor;

    Sammanfattning : A fundamental tool for containing an epidemic outbreak and mitigating its effects is early diagnostics. Currently, most of the diagnostic tests are performed by trained staff in centralized labs, which are expensive and time-consuming to establish and operate. Lack of access to such facilities could have devastating effects. LÄS MER
