  1. 1. Electrically Modified Quartz Crystal Microbalance to Study Surface Chemistry Using Plasma Electrons as Reducing Agents

    University essay from Linköpings universitet/Kemi

    Author : Pentti Niiranen; [2021]
    Keywords : Plasma enhanced chemical vapor deposition; PECVD; Quartz crystal microbalance; QCM;

    Abstract : Metallic films are important in various applications, such as electric devices where it can act as contacts. In electrical devices, the substrate typically consists of silicon dioxide (SiO2) which is a temperature-sensitive substrate. READ MORE

  3. 2. Electrical wiring of Shewanella oneidensis MR-1 with osmium polymers of different redox potentials

    University essay from Lunds universitet/Kemiska institutionen; Lunds universitet/Beräkningskemi

    Author : Laleh Tavakoli; [2021]
    Keywords : Analytical Chemistry; Bio-Analytical Chemistry; Electrochemistry; Bacteria; Osmium redox polymers; Shewanella Oneidensis MR-1; electrode; Microbial electrosynthesis; Electron transfer; Chemistry;

    Abstract : The results of studies have shown that the several applications such as microbial electrochemical system (MES), bio-electrochemical systems (BESs) and production of beneficial chemicals are due to electrochemical connection among electrodes and microorganisms. The following two factors are important in choosing the microbe mediated electrochemical biosensors: I) Binding of bacterial cells on the electrode, II) Efficient electron transfer (EET) between the electrode and the cells by a mediator.

  4. 3. Corrosion behavior of lead-free and dezincification resistant brass alloys in tap water

    University essay from KTH/Kemi

    Author : naza Alexis; [2021]
    Keywords : Corrosion; lead-free; brass; dezincification; electrochemistry; Korrosion; blyfri; mässing; avzinkning; elektrokemi;

    Abstract : Avzinkningshärdiga och blyfria mässingslegeringar används i stor utsträckning för att ersätta blyinnehållande mässingslegeringar som används för dricksvattensapplikationer. På grund av det begränsade antalet korrosionsstudier av dessa legeringar är syftet med denna studie att belysa hur vattensammansättning, temperatur och exponeringstid kan påverka legeringarnas korrosionsegenskaper.

  5. 4. Radial migration of stars, measured in N-body simulations

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Daniel Mikkola; [2017]
    Keywords : N-body; simulations; galaxies; radial migration; stars; Physics and Astronomy;

    Abstract : The purpose of Galactic archaeology is determining the history of the Milky Way (MW) Galaxy. To do this one uses observational data from stellar populations in terms of properties such as kinematics, chemistry, ages, and evolution. READ MORE

  6. 5. Evaluation of a UPLC-MS method using 18O-labelled water for the identification of hydrolytic degradants of drug substances

    University essay from Uppsala universitet/Avdelningen för analytisk farmaceutisk kemi

    Author : Viktor Kjellberg; [2015]
    Keywords : hydrolysis; degradation; degradants; 18O; 18O-water; liquid chromatography; mass spectrometry; analytical chemistry; structure eludication;

    Abstract : In this master’s thesis the hydrolytic degradation in 18O-water solutions of six drug substances has been studied. The aim was to develop a mass spectrometric method for easier identification of degradants, since hydrolysis in 18O-water will generate degradants with higher mass compared with hydrolysis in regular water.
