1. 1. Studies of Supported Catalysts for Environmental Applications: - Flow Reactor Measurements, Monte Carlo Simulations and High Throughput Screening

   Författare :Peter Thormählen; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; catalytic oxidation of carbon monoxide; supported heterogeneous catalysts; flow reactor measurements; high throughput screening; low temperature catalytic activity; cobalt oxide; platinum; temperature programmed methods; Monte Carlo simulations; environmental catalysis;

   Sammanfattning : The use of heterogeneous catalysts for environmental applications, primarily for reduction of harmful emissions from vehicles and stationary sources, has successively increased during the last three decades. Driven by emission regulations, research and development within this area attract large interest and resources, especially for automotive applications. LÄS MER

3. 2. Miniaturized cell and flow reactor for QCM-D measurements on fluids and soft matter

   Författare :Gabriel Ohlsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; soft matter materials; confined volume; Nanocell; QCM-D sensing; miniaturized flow reactor; lipid bilayer; thin films; liquid crystals;

   Sammanfattning : Thin soft matter films are frequently used in many technical applications, where phenomena taking place in the interfacial regions, control film properties and functionality. In order to optimize the latter there is a clear need of methods and tools for probing diverse physical properties of thin soft matter films confined in a nano-sized region. LÄS MER

5. 4. Fundamental Studies of Catalytic NOx Removal - Micro Kinetic Modelling, Monte Carlo Simulations and Flow Reactor Experiments

   Författare :Louise Olsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NO oxidation; Monte Carlo simulations; platinum oxide; kinetic modelling; NOx storage; barium oxide; environmental catalysis; NOx removal; platinum; flow reactor measurements;

   Sammanfattning : It is essential to decrease the CO2 emissions from vehicles, since CO2 is a greenhouse gas. One way to improve fuel economy and decrease CO2 emissions, is to run the engine with oxygen excess, so-called lean-burn operation. However, a major problem here is the reduction of the NOx in a lean atmosphere. LÄS MER

7. 5. Investigation of a Biofilm Reactor Model with Suspended Biomass

   Författare :Alma Masic; Matematik LTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wall attachment; suspended growth; substrate removal; reactor; biofilm; CSTR; mathematical model; MBBR; nitrification; optimization;

   Sammanfattning : Biofilms are compact, sessile microbial communities that attach to surfaces in aqueous environments. In wastewater treatment, they are especially important for removal of phosphorus and nitrogen, which, if released into a receiving water body, can cause severe eutrophication. LÄS MER
