  1. 1. Hydrogen in nano-sized metals : Diffusion and hysteresis effects

    Author : Wen Huang; Björgvin Hjörvarsson; Max Wolff; Gavin Walker; Uppsala universitet; []
    Keywords : Hydrogen; diffusion; hysteresis; optical technique; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : Metal hydrides can be used as hydrogen storage materials for fuel cells and batteries, and as sensors for detecting hydrogen gas. The use of metal hydrides for hydrogen storage can be hindered by poor kinetics and low capacity. Moreover, poor sensitivity, long recovery and response time, limit the applications of metal hydrides as hydrogen sensors. READ MORE

  2. 2. Epidemiology and etiology of pancreatic cancer

    Author : Jiaqi Huang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : Pancreatic cancer is one of the most devastating malignancies with an extremely high fatality, resulting that its mortality rate almost equals to incidence rate. Although primary prevention is of upmost importance, the underlying etiology of this cancer remains largely unknown. READ MORE

  3. 3. EPR Studies of Ruthenium-Manganese Complexes as Biomimetic Models for Photosystem II - Approaching Artificial Photosynthesis

    Author : Ping Huang; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; WOC; bridging-mode modification; water oxidation; EPR; Ru-Mn complexes; PSII; Artificial Photosynthesis; D donor -S sensitizer -A acceptor molecular module; High Mn valence states.; Biochemistry; Metabolism; Biokemi; metabolism;

    Abstract : In natural photosynthesis, solar energy is converted to chemical energy by photosynthetic reaction centers. In green plants and algae, Photosystem II (PSII) and Photosystem I (PSI) absorb light and utilize the charge separation reactions to convert solar energy to chemical energy. READ MORE

  4. 4. Constitutive and TCDD-induced expression of Ah receptor responsive genes with special focus on the brain and pituitary

    Author : Ping Huang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : The 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD) and related substances are ubiquitous environmental pollutants causing a number of pathological alterations, the most severe being progressive anorexia and body weight loss. The effects on body weight homeostasis suggest a possible involvement of the nervous system and neuroendocrine areas including the pituitary gland. READ MORE

  5. 5. Analysis of NMR Spin-lattice Relaxation Dispersion on Complex Systems

    Author : Yang Huang; Per-Olof Westlund; Arnold Maliniak; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NMRD; relaxation theory; hydration; MD; FFC; PrxV; OEC complex; ZSM-5; BMIM [PF6; ]; fysikalisk kemi; Physical Chemistry;

    Abstract : This thesis focus on the analysis of spin-lattice NMRD relaxation profilesmeasured in various complex systems such as proteins, zeolites and ionicliquids. Proton, deuterium and fluoride T1-NMRD relaxation profiles wereobtained from a fast-field cycling (FFC) instrument. READ MORE
