  1. 11. Diffusion in Thin Slits with Variable Aperture

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Helen Winberg; [2012]
    Keywords : ;

    Abstract : This project aims to evaluate and improve the design of an experimental setup for visualization and experimental verification of the Q-equivalent model.   The Q-equivalent model by Neretnieks (1979) is used (by SKB in Sweden) to assess mass transport of radionuclides from a broken copper canister at a repository for nuclear waste to water seeping in the host rock fractures, and the same model can be used to assess the mass transport of corrosive agents from the water to the canister.

  3. 12. Evaluation of Fullerene-Based Films Ability to Suppress Spontaneous Polymerization

    University essay from Institutionen för fysik

    Author : Merve Yesilbas; [2012]
    Keywords : fullerene; CdS; CdTe; HNO3; TPP; hydrogen plasma; Raman spectroscopy; spectroscopic ellipsometry; polymerization.;

    Abstract : The aim of the EU-FP7 Marie Curie project is ‘finding fullerene–coated surfaces with maximum photosensitizing activity.’ The effectiveness of fullerene as the singlet oxygen generator decreases in the case of fullerene is condensed to the bulk material form due to polymerization ability.

  4. 13. Aerosol light absorption measurement techniques : a comparison of methods from field data and laboratory experimentation

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Christine Walsh; [2012]
    Keywords : filter-based correction; difference method; in-situ techniques; filter-based instruments; absorption; physical geography; aerosol; Earth and Environmental Sciences;

    Abstract : Popular science Currently, there is a global drive to better understand the influences behind our changing climate. With each passing decade, the world has observed dramatic changes in weather patterns, seasonal temperatures, and our surrounding natural environments. READ MORE

  5. 14. Wet etching of optical thin films

    University essay from JTH, Kemiteknik

    Author : Curt Edström; [2010]
    Keywords : Thin film; Wet etching; Optical coating; Physical vapour deposition;

    Abstract : Evaluation of the wet etching properties of several different thin film oxidesgrown by physical vapour deposition was performed in this work. MgO, Al2O3,SiO2, TiO2, HfO2 ZrO2 and Y2O3 were coated on two types of substrates; Si andborosilicate glass and etching tests were performed in different etchingsolutions. READ MORE

  6. 15. Stabilizing factors in spatially structured food webs

    University essay from Teoretisk Biologi; Ekologi

    Author : Sara Gudmundson; [2009]
    Keywords : Dispersal; extinction risk; food web; metapopulation; noise; spatial distribution; stability; synchrony.;

    Abstract : Ecological models have problems showing the positive relationship between diversity and stability found in nature. Theory states that complex food webs have high extinction risks and low stability. However, persistent food webs found in nature are large and complex containing many interconnections between species. READ MORE
