  1. 1. On the interactions of ions and odor molecules with nanomaterials in water and synthetic urine

    Författare :Isabelle Simonsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanomaterials; Surface chemistry; Ion specific effects; MOF synthesis; Odor control; Adsorption; Synthetic urine;

    Sammanfattning : Towards the quest of finding materials to be used as adsorbents in real systems, it is crucial to understand the underlying adsorption processesfully. In many applications, adsorption occurs in biological fluids containing a vast range of ions, organic molecules, and biomolecules. LÄS MER

  3. 2. Alkaline Urine Dehydration : how to dry source-separated human urine and recover nutrients?

    Författare :Prithvi Simha; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Human urine is a renewable resource from which water, nutrients and energy can be recovered and safely recycled. This thesis presents a novel on-site technology, called alkaline dehydration, for recovering nutrients from source-separated urine. LÄS MER

  4. 3. An insight into the metabolism of New Psychoactive Substances : Structural elucidation of urinary metabolites of synthetic cannabinoids and fentanyl analogues using synthesized reference standards

    Författare :Jakob Wallgren; Johan Dahlén; Peter Konradsson; Xiongyu Wu; Mogens Johannsen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : New Psychoactive Substances (NPS) is an umbrella term covering hundreds of substances across different drug groups. Many of these substances were originally developed for therapeutic use but have later appeared on the recreational drug market. LÄS MER

  5. 4. UV-based advanced oxidation process for nutrient stabilisation and organic micropollutant degradation in source-separated human urine

    Författare :Natnael Demissie; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Urine dehydration is one of the technological approach to recover nutrients in concentrated form from source separated urine. When drying fresh urine, nitrogen loss occurs due to hydrolysis of urea into ammonia unless methods to inactivate urease enzyme are employed. LÄS MER

  7. 5. Liquid Chromatography-Mass Spectrometry as a Tool for Drug Metabolite Identification in Biological Fluids : With Application to Ketobemidone

    Författare :Ingela Sundström; Per Andrén; Douglas Westerlund; Monika Johansson; Uppsala universitet; []
    Nyckelord :Analytical chemistry; LC-MS MS; accurate mass measurement; drug metabolites; microdialysate; brain; fluorinated stationary phase; phenylboronic acid; retention mechanism; Analytisk kemi;

    Sammanfattning : Electrospray ionization (ESI) mass spectrometry (MS) in combination with liquid chromatography (LC) is an excellent tool for the identification of drug metabolites. Utilizing this hyphenated technique in combination with proper sample pretreatment, the metabolic pathways of the analgesic drug ketobemidone were investigated in human urine and rat microdialysate from blood and brain.
