1. 1. Investigating the triolein/aqueous interface and Thermomyces lanuginosa lipase activity

   University essay from Lunds universitet/Kemiska institutionen

   Author : Veronika Tolevska; [2018]
   Keywords : Spectroscopic ellipsometry; SAXS; lipase activity; interfacial activation; triolein aqueous interface; physical chemistry; fysikalisk kemi; Chemistry;

   Abstract : The triglyceride/ aqueous interface has an important role in many processes, e.g. lipase activity. Lipase is responsible for the degradation of triglycerides to smaller components, such as fatty acids. READ MORE

3. 2. Coke characterization on HZSM-5, Fe/ZSM-5, Ni/ZSM-5, and Fe-Ni/ZSM-5 from Catalytic Fast Pyrolysis of Biomass

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Isa Duman; [2018]
   Keywords : Biomass; Bio-Oil; Catalytic Fast Pyrolysis; Coke; ZSM-5; Biomassa; Bio-Olja; Katalytisk Pyrolys; Koks; ZSM-5;

   Abstract : The combustion of fossil fuels has for a long time been a problem from an environmental and sustainability point of view, especially when it comes to the emissions of atmospheric carbon dioxide. The environmental concern has for instance shifted the attention towards finding new sustainable alternatives for producing chemicals and fuels, as a substitute to today’s dependence on fossil based crude oil.

4. 3. Structure and reactivity of surface oxides on Cu(100)

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Benjamin Hagman; [2016]
   Keywords : Cu 100 ; STM; Missing row reconstruction; XPS; Reverse water-gas shift; Physics and Astronomy;

   Abstract : Adsorption of oxygen onto Cu(100) leads to formation of a well-ordered surface structure known as the `missing row' (MR) reconstruction. The aim of the work described in this thesis was to characterize the chemical properties of this MR structure, which serves as a well-defined analogue for oxidized copper surfaces used in catalysis for CO2 hydrogenation.

5. 4. The HPXPS Instrument at MAX-lab : a Powerful Tool for In Situ Catalysis Investigations

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

   Author : Niclas Johansson; [2012]
   Keywords : XPS; LEED; HPXPS; trilayer; FeO; Physics and Astronomy;

   Abstract : A new instrument for near ambient x-ray photoelectron spectroscopy investigations of surfaces has been installed at beamline I511 of the MAX-II electron storage ring at the MAX IV Laboratory. This high pressure x-ray photoelectron spectroscopy instrument is capable of surface chemistry investigations in near ambient pressures using x-ray photoelectron spectroscopy (XPS), a technique that traditionally is limited to ultrahigh vacuum.

6. 5. Characterization of an in situ chamber for catalytic studies using LIF.

   University essay from Lunds universitet/Fysiska institutionen

   Author : Jonas Evertsson; [2011]
   Keywords : Catalysts; aktivitetsmätning katalysatorer; reaktorkammare; katalytiska processer; Katalysatorer; catalytic processes; reactor chamber; activity measurements; Physics and Astronomy;

   Abstract : Populärvetenskaplig sammanfattning. Katalyskammare för aktivitetsmätning med laser. Katalysatorer är oumbärliga i såväl livsprocesser som industriella tillämpningar. Bilismen är ett exempel där katalysatorer används vid såväl bränsletillverkning som avgasrening. READ MORE
