  1. 1. Hydrogel-based pH-sensors Development and characterisation of optical and electrical pH sensors based on stimuli-responsive hydrogels

    University dissertation from Sundsvall : Mid Sweden University

    Author : Krister Hammarling; Mittuniversitetet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogel; fiber optics; printed electronics; pH; sensor;

    Abstract : The ability to measure the chemical parameter pH is of high importance in many areas. With new government regulations and evolving markets, there is a strong motivation for improving such measurements and conducting research on new types of pH sensors and sensor materials. READ MORE

  2. 2. Complex disease genetics Utilising targeted sequencing and homogeneous ancestry

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Argyri Mathioudaki; Uppsala universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ankylosing spondylitis; breast cancer; targeted sequencing; Sweden; genetics; population stratification.; Molekylär genetik; Molecular Genetics;

    Abstract : The complex disease investigations presented in this thesis aimed to provide new information regarding underlying genetics by using targeted sequencing and ethnically homogeneous cohorts. This work moved past current methodologies and addressed data stratification issues, that might have been hindering new findings.

  3. 3. Soil-living archaea: Influence of pH, carbon and nitrogen on their abundance and activity

    University dissertation from Department of Biology, Lund University

    Author : Anna Sterngren; Lunds universitet.; Lund University.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Archaea; ammonia-oxidizing archaea; soil; AOA; AOB; root exudates; gross nitrification; qPCR; pH; carbon cycle; nitrogen cycle;

    Abstract : Popular Abstract in Swedish På 70-talet upptäckte man att en grupp mikroorganismer, som man tidigare katalogiserat som bakterier, bildade en helt egen grupp. Dessa kallades ärkebakterier och fick senare namnet arkéer. READ MORE

  4. 4. Vertical III-V/High-k Nanowire MOS Capacitors and Transistors

    University dissertation from Department of Electrical and Information Technology, Lund University

    Author : Jun Wu; Lunds universitet.; Lund University.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanowire; MOSFET; MOS capacitor; C-V; XPS; MOVPE; InGaAs; InAs; High-k; RF; Track-and-hold circuit;

    Abstract : Popular Abstract in English Since 1947 when the first transistor was invented, electronics was transited into an unprecedented era. Different from a resistor that only has two terminals with the applied voltage and flowing current always obeying Ohm's law, a transistor has the third terminal in between, called "gate", which is made by, for metal-oxide-semiconductor field effect transistors (MOSFETs), an oxide layer sandwiched between the metal electrode and the semiconductor channel.

  5. 5. Nanofiltration at elevated temperatures: Influence of the combined effects of temperature, salts, pH and cleaning

    University dissertation from Faculty of Engineering, LTH at Lund University

    Author : Mattias Nilsson; Lunds universitet.; Lund University.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elevated temperatures; Electroviscous friction; Energy; pH; Economics; Nanofiltration; Pre-treatment; Salt; Swelling; Membrane performance; Cleaning; Temperature;

    Abstract : The influence of temperature, salts, pH, and various pre-treatments and cleaning on the nanofiltration (NF) performance of thin-film polyamide (PA) composite membranes has been investigated. The change in membrane performance was correlated to membrane swelling or/and electroviscous friction. READ MORE
