  1. 1. Exploration of Graphene-like 2D Materials for Energy Management and Interface Enhancement Applications

    Författare :Ya Liu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Industrial Application; Graphene-like 2D materials; Interface Enhancement; Energy Management;

    Sammanfattning : Ever since the discovery of graphene in 2004, graphene-like 2D materials and their derivatives have attracted extensive investigations because of their exceptional physical and chemical properties. At present, the study of graphene-like 2D materials is at a stage where most of their outstanding physical and chemical properties have been discovered, but the technology for incorporating them into practical commercial products is rarely revealed.

    Nyckelord :HUMANIORA; HUMANITIES; Filosofi; Philosophy;

    Sammanfattning : Essay I explores brain machine interface (BMI) technologies. These make direct communication between the brain and a machine possible by means of electrical stimuli. This essay reviews the existing and emerging technologies in this field and offers an inquiry into the ethical problems that are likely to emerge. LÄS MER

  5. 4. Theoretical Study on Chemical Structures and Stability of Molecules in Metallic Junctions

    Författare :Wei Hu; Yi Luo; Lasse Jensen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SERS; IETS; Interface; Chemical Stability; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Sammanfattning : In this thesis, we focus on the structural identification of the interface using surface enhanced Raman spectroscopy (SERS) and inelastic electron tunnelling scattering (IETS). Two different molecular junctions, namely gold/ trans-1,2-bis (4-pyridyl) ethylene/gold junction and gold/4,4'-bipyridine/gold junctions in various conditions were studied and the corresponding configurations were determined.

  7. 5. Nanostructured surfaces created by the interactions of dendrimers and oppositely charged amphiphiles

    Författare :Marianna Yanez; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PAMAM; Surfactant; SDS; Lipid; Bilayer; Model Biomembrane; Nucleolipid; DLPA; DLPU; DNA; RNA; Neutron Reflectometry; Poly amidoamine ; Interface; Adsorption; Polyelectrolyte;

    Sammanfattning : The research described in this thesis aims to understand the interactions between cationic poly(amidoamine) (PAMAM) dendrimers and small oppositely charged amphiphiles at the solid-liquid and air-liquid interfaces in relation to the bulk solution behavior. There is high interest in PAMAM dendrimers because they are well-defined polymers with a hierarchical architecture which makes them promising materials as nanocapsules and gene vectors. LÄS MER
