   Author : Fredrik Öisjöen; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; YBCO; antigen.; magnetic nanoparticles; immunoassays; antibody; SQUID; High-Tc;

   Abstract : The development of a system for immunoassays using highly sensitive high-Tc superconducting quantum interference devices (SQUIDs) and magnetic nanoparticles (MNPs) is described in this thesis.High-Tc SQUIDs were fabricated using pulsed laser deposition and photolithography. READ MORE

4. 2. YBCO nanowires to study nanoscale ordering in High-Tc Superconductors

   Author : Riccardo Arpaia; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanoscale ordering; nanoSQUIDs; nanowires; High-Tc superconductors; ultrathin films; oxygen doping; nanowire-based single photon detectors;

   Abstract : We present the realization of YBa2Cu3O7-δ (YBCO) nanowires for both basic physics studies, which could help to elucidate the microscopic mechanisms of High critical Temperature Superconductors (HTS), and for novel applications.The first part of the thesis describes an improved nanopatterning procedure, based on e-beam lithography in combination with an amorphous carbon mask and a very gentle Ar+ ion etching.

5. 3. Fabrication and noise properties of high-Tc SQUIDs with multilayer superconducting flux transformers

   Author : Maxim Chukharkin Leonidovich; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; YBCO; High-Tc SQUIDs; SQIFs; ulf-NMR; SQUID magnetometers;

   Abstract : The thesis describes the development of highTc superconducting quantum interference devices (SQUIDs) with multilayer thin film flux transformers. High-Tc SQUID magnetometers are promising in various biomedical applications, including magnetoencephalography (MEG) and ultra-low field magnetic resonance imaging (ulf-MRI). READ MORE

6. 4. The impact of genetic, environmental and life-style factors on male reproductive function

   Author : Jonas Richthoff; Malmö Reproduktionsmedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; male reproductive function; testicular cancer; smoking; Medicin människa och djur ; Medicine human and vertebrates ; cryptorchidism; sperm concentration;

   Abstract : Recent studies have indicated a decline in sperm number in the western world during the past 50 years, sperm concentration changing from 113 to 66 millions per mL. Furthermore, significant geographical differences in male reproductive function have been observed. READ MORE

7. 5. Grain Boundary Structure of YBa2Cu3O7-δ High Tc Superconductors
