  1. 1. Physicochemical and Biopharmaceutical Characterisation of Small Drug Molecules by Capillary Electrophoresis

    Författare :Eivor Örnskov; Staffan Folestad; Karin E. Markides; Morteza Khaledi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; capillary electrophoresis CE ; micellar electrokinetic chromatography MEKC ; drug; liposome; microemulsion; coating; pKa; lipophilicity; multivariate analysis; molecular descriptor; hierarchical analysis; passiv absorption; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Capillary Electrophoresis (CE) was explored as a means for physicochemical and biopharmaceutical characterisation of small drug molecules. Special attention was paid to the characterisation of acid-base and lipophilic properties of drug compounds by analysing their migration behaviour in different CE systems. LÄS MER

  3. 2. Subvalent Cluster Compounds and Synthesis in Alternative Reaction Media

    Författare :Josefin Åkerstedt; Lars Kloo; Mats Johnsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metal cluster; Zintl ion; metal-organic sandwich complex; ionic liquid; X-ray diffraction; spectroscopy; crystal structure; Inorganic Chemistry;

    Sammanfattning : With the aim of finding alternative reaction media for the synthesis of subvalent main group and transition metal cluster compounds, traditionally made through solid state reactions or in superacidic media, different alternative reaction media have been explored in this work. Room-temperature ionic liquids are amongst the more unconventional reaction media used. LÄS MER

  4. 3. Measuring Microbial Activity with an Electronic Tongue

    Författare :Charlotte Söderström; Anders Jonsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The electronic tongue is an electrochemical sensor that is composed of a sensor array of metal working electrodes, one Ag/ AgCl reference electrode, and an auxiliary electrode made of stainless steel. The working electrodes are non-selective with partly overlapping selectivity. LÄS MER

  5. 4. Thermoelectric Devices with Electronic and Ionic Conducting Polymers

    Författare :Zia Ullah; Xavier Crispin; Magnus Berggren; Marisol Martin-Gonzalez; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermoelectricity; conducting polymers; thermoelectric devices;

    Sammanfattning : The energy consumption in the world is continuously growing and the sources of energy are largely dominated by fossil fuels. However, the resources of oil, gas and coal are diminishing in capacity. Moreover the CO2 emissions arising from their combustion is a great concern because it induces climate changes that threaten our habitat. LÄS MER

  7. 5. Fungal Redox Enzymes Involved in the Oxidation of Organic Pollutants

    Författare :Enrique Terrazas; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Biokemisk teknik; Organic pollutants.; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; Biochemical technology; Laccase; Lignin peroxidase; Manganese peroxidase; Fusarium sp. strain BOL35; Biodegradation; Bjerkandera sp. strain BOL13; Bioteknik;

    Sammanfattning : This work describes the degradation of nonylphenol, toxaphene, phenanthrene, benzo[a]pyrene and dyes using fungi and their redox enzymes. Two fungi, Bjerkandera sp. strain BOL13 and Fusarium sp. strain BOL35 were isolated from different geographic area in Bolivia. LÄS MER
