  2. 21. Repurposing brownfields as urban greenspace with gentle remediation options: A circular outlook

    Author : Shaswati Chowdhury; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gentle Remediation Options GROs ; Ecosystem Services ES ; Urban Greenspaces UGSs ; Brownfields; Circular Economy CE ;

    Abstract : Circular Economy (CE) is regarded as an efficient strategy to address the challenges arising from the linear ‘take-make-use-dispose’ system of exploitation of resources. Urban land and soil are among the most exploited resources wherein brownfields, the potentially contaminated and currently obsolete land, can be considered the waste of the linear land use system.

  4. 22. Microscale Tools for Sample Preparation, Separation and Detection of Neuropeptides

    Author : Andreas Dahlin; Jonas Bergquist; Karin E. Markides; Robert T. Kennedy; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Neuropeptides; Microchip; Enhanced microdialysis; Poly dimethylsiloxane PDMS ; Electrospray ionization ESI ; Multidimensional separation; Electrochemical manipulation; Mass spectrometry MS ; Capillary electrophoresis CE ; Microdevice; Microfabrication; Micro total analysis system μ-TAS ; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Abstract : The analysis of low abundant biological molecules is often challenging due to their chemical properties, low concentration and limited sample volumes. Neuropeptides are one group of molecules that fits these criteria. Neuropeptides also play an important role in biological functions, which makes them extra interesting to analyze. READ MORE

  5. 23. Improved techniques for CE-MALDI-MS off-line coupling and MALDI-MS analysis of primarily hydrophobic proteins and peptides

    Author : Johan Jacksén; Åsa Emmer; Anna Karin/Minna Borg Karlsson/Hakkarainen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Capillary electrophoresis; Hydrophobic peptides; Matrix-Assisted Laser Desorption Ionization Mass Spectrometry; Prestructured target; Off-line interface; Silicon microcanal; Matrix; Protein cleavage digestion.; Kapillärelektrofores; Hydrofoba peptider; Matris-assisterad laserdesorptions-joniserings-masspektrometri; Strukturbelagd provplatta; Off-line interface; Mikrokanal i kisel; Matris; Proteinklyvning -spjälkning.; Analytical chemistry; Analytisk kemi;

    Abstract : Due to the hydrophobic nature of integral membrane proteins (IMP) they give rise to several difficulties concerning handling and analysis, which is not the case for the most water soluble proteins. New analysis methods are needed, where the insolubility problems of the hydrophobic proteins due to aggregation and adhesion are tackled. READ MORE

  6. 24. Towards single Ce ion detection in a bulk crystal for the development of a single-ion qubit readout scheme

    Author : Ying Yan; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2013:Yan; Ultra-violet laser spectroscopy; Single ion detection; Rare-earth-ion-doped crystals; Quantum computing; Laser stabilisation;

    Abstract : The work presented in this thesis was concerned with investigating the relevant spectroscopic properties of Ce ions randomly doped in an Y2SiO5 crystal at low temperatures (around 4 K), in order to develop a technique and an experimental set-up to detect the fluorescence photons emitted by a single Ce ion. The aim of the work was to determine whether a single Ce ion (referred to as the readout ion) can be used as a local probe to sense the quantum state of a neighbouring single-ion qubit via a state-selective interaction between the readout and qubit ion.

    Author : Joakim Romson; Åsa Emmer; Peter Dinér; Lukas Käll; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MALDI; Concentration plates; Alkyl ketene dimer; CE-MALDI-MS2; On-target digestion; Automation; Robot; Pieris napi; spermatophore; ESI-MS2; Osteopontin; MALDI; Koncentrationsprovplatta; alkylketenedimer; CE-MALDI-MS2; enzymklyvning på provplatta; Automatisering; Robot; Pieris napi; Spermatofor; ESI-MS2; Osteopontin; Kemi; Chemistry;

    Abstract : Protein analysis is important to understanding biological systems, but sample diversity necessitates a multitude of analysis techniques and methods. Challenges that are addressed include analysis of low abundance samples, fractionation to reduce sample complexity, and automation to reduce time and cost. READ MORE
