4. 3. Detection of Bio-analytes with Streaming Current : From Fundamental Principles to Novel Applications

   Författare :Siddharth S. Sahu; Apurba Dev; Shi-Li Zhang; Michel Calame; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Streaming current; Electrokinetic biosensor; Size and Charge effects; membrane protein profiling of extracellular vesicles; sandwich immunoassay; charge-labelled antibodies; multiplexed detection; exosome heterogeneity;

   Sammanfattning : A biosensor based on streaming current is a new and relatively unexplored subject with significant potential. This thesis attempts to gain a deeper understanding of the governing principles, and then exploit them to further improve its performance as well as develop novel applications. LÄS MER

5. 4. Atomistic Modelling of Materials for Clean Energy Applications : hydrogen generation, hydrogen storage, and Li-ion battery

   Författare :Zhao Qian; Rajeev Ahuja; Börje Johansson; Antonio Ferreira da Silva; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Renewable energy; Materials science; Hydrogen production; Hydrogen storage; Li-ion battery; Density functional theory; SRA - Energy; SRA - Energi; SRA - E-Science SeRC ; SRA - E-vetenskap SeRC ;

   Sammanfattning : In this thesis, a number of clean-energy materials for hydrogen generation, hydrogen storage, and Li-ion battery energy storage applications have been investigated through state-of-the-art density functional theory.As an alternative fuel, hydrogen has been regarded as one of the promising clean energies with the advantage of abundance (generated through water splitting) and pollution-free emission if used in fuel cell systems.

7. 5. NMR studies of DNA structure and counterion behaviour

   Författare :Lorens van Dam; Gary Drobny; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical Chemistry; fysikalisk kemi;

   Sammanfattning : DNA is a polymer of nucleotides, each nucleotide consisting of a negatively charged phosphate group, a ribose sugar unit, and a purine or pyrimidine base. The secondary structure of DNA is commonly a double-helix with Watson-Crick paired bases. Several secondary structures, all with these features, are observed for DNA. LÄS MER
